No new login, no portal, nothing installed on the merchant's theme. What a customer can change: edit the address, change the quantity, swap a variant, add or remove an item, or cancel the order outright. An order Tacey cannot safely edit is refused up front, in the UI, rather than guessed at. Beyond editing, Tacey runs post-purchase upsells on the same order-status surface, and sends pre-ship reminder emails before the merchant's edit window closes. Every edit is written to a permanent record: what changed, what it cost, and who asked for it, on every plan from the first order. Separately, a merchant can combine two already-paid orders from the same customer into one, before they ship, from the app's admin. This is Order Merge: a merchant-initiated action, distinct from the customer-facing editing above, and it never touches either original order's captured payment. Money never moves without an explicit confirmation. There is no setting that turns automatic charges or refunds on by default. Tacey is built by ONDUTYOPS LLC. Founder: Odera Joseph Echendu. Solo founder, no VC. Live on the Shopify App Store. ### What Tacey is NOT Not a fraud product. Not an AI agent. Not a 40-app operations toolkit. Not an analytics platform. Not a helpdesk. Not a subscription manager. Four jobs, one customer surface. ## How Order Editing Works When a customer places a Shopify order, the merchant sets an edit window (a number of minutes, counted from the moment Shopify marks the order processed). Until that window closes, the order-status page Shopify already emails the customer carries an editing surface: the customer can fix a wrong shipping address, change the quantity of a line item, swap a variant, add or remove an item, or cancel the order outright. Fulfillment waits. Tacey holds the order back from the merchant's warehouse until the edit window closes, so a picker never works from an order that is still changeable underneath them. The moment the window closes, the hold releases and the order fulfills normally, whether or not the customer touched anything. The moment the window closes, editing is over. There is no override, no grace period, and no path for the customer to request a change after that point through Tacey. The order is locked exactly when the merchant's warehouse becomes free to pick it. ## Orders Tacey Refuses To Edit An order that cannot be safely edited is refused up front, in the UI, with a stated reason, never guessed at, and never silently dropped. Six order classes are permanently ineligible, checked once per order: 1. **Paid with Shop Pay Installments**: the payment plan cannot be safely re-split by an edit. 2. **Created by another app**: the order did not originate from the store's own web checkout, so Tacey does not assume authority to change it. 3. **A local-delivery order**: local delivery logistics are not compatible with a mid-flight address or item change. 4. **Payment still pending**: an order Shopify has not yet confirmed as paid cannot be edited. 5. **Placed in a different currency than the store's**: a currency mismatch on the order makes a money-safe edit unreliable. 6. **Placed before 2019**: orders that old predate data guarantees Tacey depends on to edit safely. A merchant can also name specific order tags to block from editing entirely, an escape hatch for orders they want to handle by hand regardless of what Tacey would otherwise allow. And once an order's edit window has closed, it is refused for that reason alone, independent of the six classes above. None of these six classes is about whether Tacey trusts the customer. They are about whether an edit can be made to that order without creating a mismatch between what Shopify's systems believe happened and what actually did. ## Order Merge Two orders from the same customer, placed separately and both already paid, can end up needing to ship together, such as a customer who checked out twice by mistake, or added a second order before the first one shipped. From the app's admin, a merchant can combine two such orders into one before either ships. Merging never moves money. Both orders have already been paid in full before a merge tool ever runs, so the merged order collects no new charge, and the order being absorbed is cancelled without a refund: its payment stays exactly where it already was. This is a deliberate design choice, not a platform requirement, because a merge that refunded one order and recharged the other would ask the customer to be charged twice for something they already paid for once. The surviving order keeps its own order number; nothing about the merge creates a third order. Both order records stay visible in Shopify exactly as they were, and every merge is written to the same permanent record Tacey keeps for every edit: which two orders were involved, what moved to the surviving order, and that no payment changed hands. Order Merge is a merchant-admin action, not a customer-facing feature. It does not appear on the order-status page a customer sees, and it does not gate on plan: it is available on every plan, at no additional cost. Two orders cannot be merged when: they belong to different customers, they are priced in different presentment currencies, either has already been partially fulfilled, either has an active return in progress, or either has already been merged once before. A merge tool that hit one of these refuses the pair up front, with the reason stated, rather than attempting a merge it cannot safely complete. Full detail: https://tacey.app/order-merge ## Address Validation Every order's shipping address is checked against a real-time address verification service immediately after the order is placed, never during checkout, so a validation call can never add friction or cost a sale. If the validation provider is unreachable or slow, the order proceeds untouched and is marked "not checked": Tacey never substitutes a guess for a real result, and it never marks an address verified when it could not actually verify it. This is a deliberate fail-open design. A bad minute at a vendor must never hold up a merchant's order. Merchants can scope validation by country: check every order (the default), check only an allowed list of countries, or check every country except a blocked list. Where a shipment's country cannot be determined, or where the merchant's setting is unrecognized, Tacey validates anyway. The failure direction for a broken setting is always "check it," never "silently stop checking," because the second is invisible to the merchant. Validation never blocks a purchase and never blocks fulfillment on its own. What it produces is a record and, when the merchant has address editing turned on, a reason for the customer to be shown the edit surface. Validation and editing are two of Tacey's four jobs, and neither gates the other: a merchant can run address validation with editing turned off, or run editing with validation off. ## The Edit Record Every edit Tacey makes to a live order is written to a permanent record, whether the edit succeeded, failed, or is still unconfirmed: what the order was before, what it became after, what money moved, who asked for the edit (the customer, the merchant, or Tacey itself), and whether the change has been independently confirmed against Shopify's own state. The write happens after the edit attempt, unconditionally, not only on success, so a failed or partial edit is just as visible in the record as a clean one. This is the single mechanism that makes an edit trustworthy after the fact: a merchant reconciling their books can answer "what actually happened to this order" without re-deriving it from Shopify's raw order history. The record is exportable to CSV and JSON on every plan, from the first order. ## Post-Purchase Upsells Tacey can offer an additional item on the same order-status page a customer uses to edit their order, inside the same edit window. Because the item rides on the original order rather than becoming a second purchase, it does not add a second shipping charge. ## Pre-Ship Reminders Tacey sends reminder emails to the customer before the merchant's edit window closes, so a customer who wants to fix or change something has a real chance to notice before the order locks and ships. ## Boundaries: What Tacey Does Not Do - Tacey does NOT run at checkout. Zero conversion impact, zero checkout-flow changes. - Tacey does NOT move money automatically. A refund or an extra charge always needs an explicit confirmation; no money control defaults on. - Tacey does NOT edit an order after its window has closed, and does NOT edit any of the six permanently ineligible order classes. - Tacey does NOT block or delay fulfillment beyond the merchant's own edit window. - Tacey does NOT mark an address verified when the validation provider could not be reached. It is marked "not checked" instead. - Tacey is NOT a fraud-detection product, an AI order agent, a 40-app operations toolkit, an analytics platform, a helpdesk, or a subscription manager. - Tacey does NOT gate any feature behind a higher-priced plan. Plans differ by order volume only. - Tacey does NOT offer a perpetual free tier. Every plan is a paid plan with a 14-day free trial. - Order Merge does NOT create a third order, and does NOT move money. The surviving order keeps its own id; the absorbed order is cancelled with no refund and its original payment is never touched. ## Security & Privacy Tacey is a Shopify embedded app and is fully GDPR compliant. A shopper's right-to-erasure request is honored end to end: their address and order-edit records are deleted or redacted from Tacey's systems. On uninstall, a merchant's data is retained only through the short window Shopify gives a merchant to reinstall and keep their settings, then fully deleted once Shopify confirms the uninstall is final. Tacey does not sell merchant or customer data to third parties. ## Glossary - **Edit window**: the length of time, set by the merchant, during which a customer can change their own order on the order-status page. Fulfillment waits for it to close. - **The record / reconciliation ledger**: the permanent row written for every edit: before, after, money moved, who asked, whether it was independently confirmed. - **Not checked**: the state an address is marked in when the validation provider could not be reached. Distinct from, and never converted into, "verified." - **Fail open**: validation never blocks or delays an order; a provider outage always resolves in the order's favor. - **Refused**: the up-front, stated decision that a specific order cannot be edited, shown in the UI rather than failing silently or guessing. - **Order-status page**: the Shopify page a customer already receives by email after ordering. Tacey's entire customer-facing editing, upsell and reminder surface lives here; there is no separate portal. - **Order Merge**: a merchant-admin action combining two already-paid orders from the same customer into one before they ship. No new charge, no refund, no third order. Distinct from customer-facing editing. ## Pricing, Full Detail One product, six sizes.

No. Nothing runs during checkout. Every check happens after payment, on the order Shopify has already confirmed, so there is no path by which Tacey can cost you a sale. ### What happens if the address service is down? The order goes through untouched and is marked as not checked. We fail open: a bad minute at a validation provider must never hold up an order. It is never marked verified when we could not verify it. ### Where exactly can customers edit an order? On the thank you page Shopify shows right after checkout, and on the order status page it emails them afterwards. Tacey appears on both. There is no new login, no portal, and nothing for you to install on your theme. ### Can a customer change something after it ships? No. The window you set closes before fulfillment, and once your warehouse can pick the order it is locked. Nothing changes underneath a picker. ### Does money move on its own? Never. A refund or an extra charge always needs an explicit confirmation, and no money control is switched on by default. ### What if I do not want customers editing orders? Turn editing off and keep address validation and reminders. The four jobs are independent. ### Which countries can you validate? Validation runs through Geocodio for the US and Canada, and Google's Address Validation API for Mexico and international addresses. Where an address cannot be checked it is marked not checked rather than guessed. ### Do the upsells cost my customer extra shipping? Not when the item rides on the original order. That is the point of offering it inside the edit window rather than as a second purchase. ### How does the fulfillment hold work? Tacey holds the order until the edit window closes, then releases it. Your warehouse sees a normal order, just slightly later. ### Which languages do you support? Every screen your customer sees is available in 21 languages, and it follows the language Shopify already knows they are browsing in. ### How does billing work? Through Shopify, on your existing app bill, monthly. Change or cancel the plan yourself at any time. ### Is there a free plan? No. Every plan has a 14-day free trial instead, and you are not asked for anything to start it that Shopify has not already got. ### What happens when I go over my order count? Address checking pauses and we tell you well before it does. Your orders and your customers' edits carry on as normal. ### Do I get fewer features on the cheapest plan? No. Starter is the same product as High Volume. The only difference is how many orders a month you can send through it. ### How do you count a month? From the moment you subscribed, rolling forward, not from the 1st. Annual plans get the same monthly count, not a yearly one. ### Can I change plans? Yes, through Shopify's own billing. An upgrade applies as soon as Shopify confirms it, and your new count applies from that moment. ### What happens to my data if I uninstall? Your record stays available while the app is installed. After you uninstall, Shopify tells us to erase your data and we do. ## Free Tools (browser-based, no install required) Tacey publishes 7 free tools at https://tacey.app/tools. - [Address Type Detector](https://tacey.app/tools/address-type-detector) - [Address Validator](https://tacey.app/tools/address-validator) - [Shopify Theme Detector](https://tacey.app/tools/shopify-theme-detector) - [Shopify App Stack Detector](https://tacey.app/tools/shopify-app-stack-detector) - [Shopify Sales Activity Estimator](https://tacey.app/tools/shopify-sales-estimator) - [Shopify Agentic Readiness Audit](https://tacey.app/tools/agentic-readiness-audit) - [Universal Product Lookup](https://tacey.app/tools/universal-product-lookup) ## Comparison Pages Tacey publishes 3 head-to-head comparison pages comparing Tacey to other approaches to Shopify order editing. ### Tacey vs Triom.

After approving a plan change on Shopify's own pricing page, you could sometimes land on a broken page instead of back inside Tacey. You are now always returned to your dashboard, with your new plan applied. ### Tacey now speaks all of its supported languages correctly - **Released**: September 1, 2026 | **Category**: bugfix - **URL**: https://tacey.app/changelog/tacey-now-speaks-all-of-its-supported-languages-correctly-2026-09-01 If your Shopify admin is set to a language other than English, several things could quietly go wrong: a few screens stayed in English behind the scenes, a small number of regional languages fell ba... If your Shopify admin is set to a language other than English, several things could quietly go wrong: a few screens stayed in English behind the scenes, a small number of regional languages fell back to English instead of showing your actual language, and choosing a language yourself in Tacey could get overwritten by your store's own setting the next time you signed in. All of this is now fixed. The language you choose is the language you keep, everywhere in the app, and it now starts correctly in every language Tacey supports from the moment you install it. ### Opening Tacey in your own language now translates the whole page - **Released**: September 1, 2026 | **Category**: bugfix - **URL**: https://tacey.app/changelog/opening-tacey-in-your-own-language-now-translates-the-whole-page-2026-09-01 The "Orders" link in the left hand navigation used to stay in English no matter what language you had selected, while everything else on the page translated.

The "Orders" link in the left hand navigation used to stay in English no matter what language you had selected, while everything else on the page translated. It now translates along with everything else. The language switcher itself also moved: it now sits at the top of the page next to the page title, instead of running the full width of the screen. ### The Orders page now shows an honest empty state - **Released**: September 1, 2026 | **Category**: bugfix - **URL**: https://tacey.app/changelog/the-orders-page-now-shows-an-honest-empty-state-2026-09-01 A store with no orders yet was being shown sample rows on the Orders page that were never real orders. It now shows a plain, clearly labelled empty state until you have real orders to see. A store with no orders yet was being shown sample rows on the Orders page that were never real orders.

The three summary numbers on your dashboard, addresses verified, corrections made, and reshipping avoided, used to stack in a single column even on a wide screen. They now line up side by side on larger screens, and only stack when the screen is genuinely narrow. The reshipping figure also now shows in your store's own currency instead of always showing US dollars. ### Clicking Tacey's name in your Shopify sidebar now opens Tacey - **Released**: September 1, 2026 | **Category**: bugfix - **URL**: https://tacey.app/changelog/clicking-taceys-name-in-your-shopify-sidebar-now-opens-tacey-2026-09-01 Clicking the app's own name in your Shopify admin sidebar could sometimes show a blank placeholder page instead of Tacey. It now always opens straight into your dashboard. Clicking the app's own name in your Shopify admin sidebar could sometimes show a blank placeholder page instead of Tacey. It now always opens straight into your dashboard. ### Refreshed welcome screen - **Released**: May 4, 2026 | **Category**: improvement - **URL**: https://tacey.app/changelog/refreshed-welcome-screen-may-2026 The first thing you see after installing Tacey is now a proper introduction, 2-minute video, step-by-step explanation, and a tour of the 24+ tools. Pricing moved to the final step. We heard from a few merchants that the old welcome jumped straight to plan pricing before showing any value, this fixes that. The new welcome flow walks through what Tacey reads, decides, and acts on automatically, plus the full Toolkit before you ever pick a plan. ### Choose any sensitivity mode on any plan - **Released**: May 4, 2026 | **Category**: improvement - **URL**: https://tacey.app/changelog/sensitivity-modes-on-every-plan Conservative, Balanced, and Aggressive sensitivity are now available to every Tacey merchant, Scout included. Sensitivity is a preference, not a tier. Switch modes anytime from Settings → Agent Configuration. We removed the upgrade gate because picking how strict the agent is shouldn't depend on what plan you're on, it should depend on your store. ### Bulk actions run in the background - **Released**: May 4, 2026 | **Category**: feature - **URL**: https://tacey.app/changelog/bulk-actions-background-progress-bar Hold, release, dismiss, evaluate, approve, or contact 50+ orders at once with a live progress bar. Leave the page, Tacey keeps working. Big batches no longer time out, and you don't have to keep the tab open until the last order is done. Applies across Order Watch, Observed orders, and the Escalation Queue. ### Re-run any past order through the latest AI - **Released**: May 4, 2026 | **Category**: feature - **URL**: https://tacey.app/changelog/decision-replay-v2-rerun Decision Replay now actually re-runs a past order through Tacey's current decision engine, fresh confidence + reasoning, side-by-side against the original. Available on Commander. Open any flagged or resolved order in Decision Replay, click 'Re-run with current AI', and you'll see what the agent would decide today. ### Search rule templates by what you want them to do - **Released**: May 4, 2026 | **Category**: feature - **URL**: https://tacey.app/changelog/rule-template-search-by-intent Type what you want, 'hold high-value first orders', 'flag PO box addresses', 'auto-pass repeat customers', and Tacey ranks the closest templates from your library. No more scrolling categories looking for the right starting point. The library has a search bar at the top now. ### See similar past escalations alongside a new one - **Released**: May 4, 2026 | **Category**: feature - **URL**: https://tacey.app/changelog/similar-past-escalations-panel When you open a flagged order, a new 'Show similar' panel surfaces the three most similar escalations from your last 90 days. Helps you spot recurring patterns and reuse the decision you made last time on a near-identical order. ### Per-tool settings on Page Content Audit and AVS Cross-Reference - **Released**: May 3, 2026 | **Category**: feature - **URL**: https://tacey.app/changelog/page-content-audit-avs-settings-tabs Two more Toolkit cards picked up Settings tabs, tune thresholds for content quality and decide how partial AVS matches should be surfaced. Page Content Audit lets you tune the thresholds for 'title too short' and 'thin body'. AVS Cross-Reference lets you decide how partial matches should resolve (PASS, REVIEW, or DECLINE). Every change to AVS settings is recorded in your shop audit log. ### Live shipping status now visible alongside Tacey decisions - **Released**: May 3, 2026 | **Category**: feature - **URL**: https://tacey.app/changelog/live-fulfillment-status-in-queues Order Watch and the Escalation Queue now show Shopify's live fulfillment status (Fulfilled, Partially fulfilled, On hold, etc.) right next to Tacey's decision badge. If your warehouse already shipped an escalated order, or Shopify itself put a fulfillment on hold, you'll see that without leaving the queue. Updates in real time as fulfillments move through their lifecycle. ### Clearer settings audit log - **Released**: May 2, 2026 | **Category**: improvement - **URL**: https://tacey.app/changelog/settings-audit-log-readable Every Event Explorer settings row now spells out exactly what changed, with units. New 'Who' column shows which member of your team made the change. Before: cryptic rows like '0 → 24' with the generic message 'A setting was changed by the merchant.' Now: 'Hold window, hours: 0 hours → 24 hours', 'Storefront language: English → Dutch'. Per-staff name attribution coming next; for now the column shows the shop owner for in-Tacey changes, 'Shopify (system sync)' for Shopify-driven changes, and 'Tacey support team' for changes our team makes on your behalf. ### Faster, more reliable behind the scenes - **Released**: May 1, 2026 | **Category**: behind-the-scenes - **URL**: https://tacey.app/changelog/behind-the-scenes-may-2026-perf Quietly shipped the foundation for richer in-app analytics, faster diagnosis, and real-time alerting on slow AI inference. You won't see anything new on the surface, but reports load with more accurate data, page-speed regressions get caught faster, and any background processing hiccup now alerts our on-call team in real time. The same hook drives a smarter alert when our AI takes longer than usual on a decision, so we catch slow inference before it reaches your dashboards. ### Tacey is live on the Shopify App Store - **Released**: May 1, 2026 | **Category**: feature - **URL**: https://tacey.app/changelog/live-on-shopify-app-store Tacey is now publicly listed at apps.shopify.com/tacey. Anyone can install it from a search. Approved 2026-05-02. We are happy to announce that Shopify has now approved! You can now search Tacey and install it safely on your Shopify app store! ### Smarter language matching - **Released**: April 30, 2026 | **Category**: improvement - **URL**: https://tacey.app/changelog/smarter-language-matching When you change Tacey's display language, marketing emails from us automatically switch to match, instantly, no waiting for the next page load. We added the same automatic match for time zones, so reminders arrive at sensible local hours. ### Customer reply addresses, fixed - **Released**: April 30, 2026 | **Category**: bugfix - **URL**: https://tacey.app/changelog/customer-reply-routing-fix Replies to address-fix emails now reliably reach you, the merchant, never our support team by mistake. Previously a small percentage of replies on one email type were misrouted; now the entire customer-email surface routes back to your inbox of choice (the address you set in Settings → Notifications). ### Intel Hub v2, 12 cards for customer intelligence - **Released**: April 24, 2026 | **Category**: feature - **URL**: https://tacey.app/changelog/intel-hub-v2-12-cards A new Intel Hub takes Tacey beyond order validation into customer-level insights: spend tiers (RFM), cohort analysis, win-back segments, marketing consent reports, and more. 12 new dashboards: Repeat Flagged Customers, Loyalty Segment Export, Win-Back Segments, Marketing Consent Report, Customer Spend Tiers (RFM, Platinum/Gold/Silver/Bronze), Cohort Analysis, Duplicate Customer Finder (deterministic + AI-assisted), Abandoned Cart Recovery (with Shopify-coexistence detection), Checkout Abandonment Report, Customer Notes Bulk Annotator, Address Quality Score per Store, and Repeat Flagger. ### Catalog Health, 9 bulk tools for product hygiene - **Released**: April 21, 2026 | **Category**: feature - **URL**: https://tacey.app/changelog/catalog-health-9-bulk-tools A new tab inside the Toolkit covering the most common SKU-level cleanup tasks: dedup products, fix missing publication channels, dead-stock detection, lifecycle changes, inventory transfers. Find duplicate products, find products missing publication channels, find dead stock, run lifecycle changes (active/draft/archived) in bulk, adjust inventory in bulk, transfer inventory between locations, normalize variant option names, bulk-update metafields, and a unified history tab showing every bulk action with row counts and timestamps. ### Discount Intelligence, 11 cards - **Released**: April 19, 2026 | **Category**: feature - **URL**: https://tacey.app/changelog/discount-intelligence-11-cards A new Toolkit section for merchants running heavy promotions: discount overview, hygiene cleanup, gift-card balance, A/B comparison, stacking detection, fraud detection on discount abuse, and more. 11 cards: discount overview dashboard, hygiene cleanup, gift-card balance report, A/B comparison, stacking detection, expiry manager, automatic-discount toggle, fraud detection on discount abuse, settings, manual gift-card issuance, and a discount creator that walks you through making a new code. ### Onboarding wizard now suggests sensitivity - **Released**: April 17, 2026 | **Category**: improvement - **URL**: https://tacey.app/changelog/onboarding-sensitivity-suggestion The setup wizard analyzes your store's recent order pattern and recommends a starting sensitivity level (Conservative / Balanced / Aggressive). You can still pick anything; the suggestion is just a smarter default based on what your store looks like. ### Better customer fix-page emails - **Released**: April 15, 2026 | **Category**: improvement - **URL**: https://tacey.app/changelog/personalized-fix-email-subjects Subject lines on customer fix-page emails are now generated per-order using the customer's name, your store name, and the specific address issue.
