TightShip Labs builds quiet watchdog apps for Shopify stores. Our first, LeakWatch, catches two leaks almost every store has: shipping labels that expire unused, and paid orders that never fully ship.
LeakWatch launches soon in the Shopify App Store. Until then, the guides below cover both fixes by hand.
Never lose money to a forgotten shipping label again.
$29/month · 14-day free trial · one flat plan
Neither shows up in Shopify's reports. Most stores find them the expensive way — a lost credit, or an angry customer.
Leak one
You buy a label, then the order gets cancelled, duplicated, or held — and the label sits there unused.
Shopify lets you void a label for credit only within 30 days of purchase. No warning at day 25, no flag at day 29 — on day 31, the money is gone.
LeakWatch flags every unused label while it can still be voided — and alerts you immediately if a labelled order is cancelled.
Leak two
An order gets paid, half of it ships, and the rest sits. Shopify's own reports can't see a partially fulfilled order's missing items.
Most stores find out from the customer — after the refund, the chargeback, and the one-star review.
LeakWatch's daily scan finds orders unfulfilled or partially fulfilled beyond your threshold, with the exact missing items and the dollar value unshipped.
Every open leak lives in one dashboard in your Shopify admin — order, age, and money at stake — with one-click links to the order.
Install it and it starts watching the same day. Nothing to configure, nothing to remember.
Every day, LeakWatch reads your labels and open orders, read-only — it can look, never change.
Label alerts escalate at 21, 25, and 28 days, while there's still time to void. Stuck orders surface once they pass your age threshold.
Findings arrive in one daily email. No repeats about the same problem, and resolved issues close themselves.
A watchdog shouldn't need watching. LeakWatch is deliberately small and quiet.
Labels and stuck orders, checked every day — nothing to configure or remember.
At 21 / 25 / 28 days, before the 30-day void window closes — plus an instant flag when a labelled order is cancelled.
The exact missing items on partially fulfilled orders, with the unshipped dollar value.
One daily email per escalation. No duplicates, no alert fatigue.
Every finding links straight to the order in your admin, so fixing it takes seconds.
LeakWatch can look, never touch — it never changes an order, voids a label, or contacts customers.
One saved label or one avoided refund a month and LeakWatch has paid for itself. $29/month, 14-day free trial — in the Shopify App Store at launch.
The same checks LeakWatch automates, step by step — useful whether or not you install the app.
Shipping labels
Unused labels are refundable — but only inside a 30-day window, and Shopify never warns you it's closing. Where to find them, and how to void them in time.
Read the guide →Fulfillment
The unfulfilled-orders view treats a half-shipped order as handled. Why partial orders slip through — and a weekly routine that catches them before your customers do.
Read the guide →Operations
A short weekly pass over labels, partial orders, and cancelled orders that catches nearly every fulfillment money leak — the manual version of what LeakWatch does daily.
Read the guide →Refunds go out, but the returned goods don't always come back — and short returns rarely get reconciled against the money that already left. RefundWatch will match every refund against what actually arrived, and flag the mismatches. Same approach as LeakWatch: a daily sweep, an exceptions inbox, one digest.
When you buy a shipping label through Shopify, the order doesn't always go out. It gets cancelled, duplicated, edited, or held — and the label you paid for sits unused. That money isn't lost yet: Shopify lets you void an unused label for a credit — but only within 30 days of purchase.
After day 30, the label can't be voided. The money is gone, with no way to appeal it.
Shopify does not warn you: no notification at day 25, no flag at day 29, no report listing unused labels by age. A label bought for an order cancelled the same afternoon quietly expires a month later — usually discovered, if at all, weeks after the window has closed.
A few things worth knowing:
There's no single screen for this, so do a regular pass: work through recent orders that were cancelled, duplicated, edited after label purchase, or held, and check each for a label that never shipped. Weekly is usually often enough — but check cancelled orders the same day, since an order leaving your working queues is exactly how its label gets forgotten.
The habit that works: whenever an order is cancelled, duplicated, or held, void its label in the same sitting. The window only hurts when the label outlives your memory of the order.
LeakWatch scans every purchased label daily and alerts you at 21, 25, and 28 days — plus immediately when a labelled order is cancelled — with a link straight to the order.
See LeakWatchMost stores watch their unfulfilled orders — the obvious queue: paid, not shipped, needs attention. The problem is what that queue leaves out: the partially fulfilled order.
Say an order has three items. Two ship today; the third waits on a restock, a transfer, or someone noticing it's missing. The moment the first shipment is created, the order becomes Partially fulfilled — and leaves the unfulfilled queue you were watching.
It doesn't land in any equivalent "still owed" queue — there's no default view listing partial orders with their missing items and wait times. The order looks handled. The customer is still owed a product they paid for.
Usually from the customer: a "where's the rest of my order?" email two or three weeks later — by which point the fix is a refund, an expedited reship at your cost, or a chargeback, plus the review. The item's value sat unshipped the whole time, and no dashboard said so.
Splitting a shipment isn't a mistake — multi-location inventory, backorders, and pre-orders all create partials on purpose. The failure is that nothing tracks the open remainder. A healthy partial has a plan and a date; a stuck one has neither — and in the order list, they look identical.
Weekly is the minimum cadence that works. The oldest-first sort matters more than the frequency: stuck orders are, by definition, the ones that have been waiting longest.
It finds paid orders unfulfilled or partially fulfilled beyond your threshold, with the exact missing items and unshipped dollar value — one digest, not one angry email at a time.
See LeakWatchFulfillment leaks are small, quiet, and cumulative: a label here, a half-shipped order there. None show up as a line item anyone reviews. A short weekly audit — the same three passes, in the same order — catches nearly all of them while they're still fixable.
The audit only works if it happens when nothing seems wrong — leaks are invisible precisely because the queues look fine. Same day, same time, same three passes: fifteen minutes a week, spent while every problem it finds is still cheap to fix.
Know the limits: the audit depends on someone remembering to run it, and a label bought the day after audit day ages nearly a full week before anyone looks. It's a good net. It isn't a watchdog.
Same checks — labels nearing their void deadline, partial orders going stale, cancelled orders with live labels — run every day, with findings in one email digest.
See LeakWatchLeakWatch is a Shopify application operated by TightShip Labs ("we", "us"). This policy explains what data the app accesses, why, and what we do with it.
When a merchant installs LeakWatch, Shopify grants the app read-only access to:
LeakWatch is read-only. The app cannot create, modify, or delete orders, fulfillments, products, or customer records, and it never initiates payments or shipments.
For each alert the app generates, we store a record containing the order reference, the type of issue detected, its severity, and when it was detected — so the app does not send duplicate alerts and can show resolved issues. We store your store's domain and the contact email used for alerts. We retain these records while the app is installed.
If enabled, LeakWatch sends email digests of newly detected issues to the store contact email (or an address you specify). Alert emails contain order references and issue summaries — the same information visible in the app's dashboard.
When LeakWatch is uninstalled, we delete your store's session data promptly and delete stored alert records within 30 days, except where retention is required by law. Shopify's mandatory privacy webhooks (customer data request and data erasure) are honored: LeakWatch does not store end-customer personal data beyond what appears in order records processed transiently for detection, and any erasure request routed to us is actioned within the timeframe Shopify requires.
Data is transmitted over encrypted connections (HTTPS/TLS) and stored in access-controlled systems. Access to production data is limited to the operator for support and maintenance.
Questions about this policy or your data: support@tightshiplabs.com.
We may update this policy as the app evolves; the current version will always be posted at this URL, and material changes will be noted with a new "last updated" date.
TightShip Labs builds small, focused apps for Shopify stores — no suites, no all-in-one platforms. Each app watches one kind of quiet money loss: the kind that never appears in a report and is usually discovered too late to fix.
Our first app, LeakWatch, watches fulfillment: labels that expire unused when Shopify's 30-day void window closes silently, and paid orders that ship halfway and then sit. It scans daily, reports in one digest, and is read-only by design — it finds problems and points; it never touches your orders, money, or customers.
The second, RefundWatch, is in development — the same watchdog pattern, pointed at the returns desk.
The philosophy is simple: small tools, honest claims, quiet inboxes. We'd rather an app do one job provably well than ten jobs approximately.
