Stocky alternatives: an honest migration guide.

If you run inventory on Stocky, you have a deadline: Shopify has confirmed that the app stops working after August 31, 2026. Search interest in a Stocky alternative is spiking for a simple reason — thousands of stores built their reordering habits inside an app that is about to disappear, and most of the advice out there is either a sales page wearing a helpful hat, or a shrug.

This guide tries to be neither. We build in this space (more on exactly where we fit — and where we honestly don't yet — near the end), but the bulk of what follows is vendor-neutral: the precise timeline, what you lose, what to export before it's gone forever, a 20-minute framework for choosing a replacement, and a reorder-point formula you can run in a spreadsheet this afternoon while you decide.

Two details in that table deserve a second look. First, the API shutdown means the blast radius is bigger than the app itself — if your accountant's tooling, a custom report, or a Zapier flow reads from Stocky, it dies the same day. Second, the feature removals already started a year ago: if your min/max forecasting quietly stopped updating in mid-2025, that wasn't you.

Stocky was never glamorous, but it quietly did a lot. When it goes, this is what leaves with it:

• Demand forecasting and reorder suggestions — the math that told you what to buy and when.
• Purchase orders — creating, sending, receiving, and the paper trail of all of it.
• Supplier management — contacts, terms, and which products come from whom.
• Stocktakes — structured counts with variance history.
• Low-stock reporting tuned for POS-heavy, multi-location retail.

There's also a quieter loss: context. Years of purchase orders and stocktake history encode how your store actually behaves — which suppliers run late, which seasons spike, which products you chronically under-order. None of that migrates anywhere automatically.

Whatever you migrate to, future-you needs the raw material. Export while the app still opens:

• Purchase order history — export to CSV, including received quantities and dates.
• Stocktake history — your variance record is your shrinkage story.
• Inventory reports you actually reference — save the views, not just the raw data.
• Product cost data — verify costs live in Shopify (or your files), not only in Stocky.
• Your current reorder settings — screenshot or note the min/max values you trusted, even though the feature already stopped updating.

One warning that surprises almost everyone: supplier records can't be exported from Stocky at all. If your supplier contacts, terms, and product-supplier mappings live only there, rebuild them now — from invoices and email threads — while it's a chore instead of an emergency.

A deadline is a bad reason to panic — and a very good reason to choose deliberately.

The deadline is August 31; it's late July as we publish this. Six weeks is comfortable — if the order is right. Working backward:

• This week — run the export checklist above and rebuild supplier records. Data first; every later step depends on it.
• By August 7 — shortlist two replacements with the framework below, and start a trial of your front-runner on your real catalog.
• August 8–22 — run the new tool in parallel: let it recommend, compare its numbers against your own judgment (and the reorder-point math below), wire up integrations.
• August 23–29 — cut over while Stocky still works, so you can double-check against it instead of against your memory of it.
• August 31 — the shutdown should feel like a formality, because you left a week of slack for the surprise every migration has.

Before comparing logos, write down answers to six questions. They'll eliminate most options faster than any feature grid:

• What did you actually use in Stocky? If it was 90% reorder suggestions, don't buy an ERP to replace it.
• Do you need purchase orders as documents (sent to suppliers, received against), or just reorder math?
• How many locations — and do transfers between them matter to you?
• What must it integrate with beyond Shopify — accounting, 3PL, POS?
• How does the pricing scale — flat per-store, or metered in a way that spikes exactly when you grow?
• Does it only tell you what's wrong, or can it take the next step for you — and if it acts, can you approve each action before it happens?

A note on the first row, because it's Shopify's own recommendation: the built-in inventory features have quietly improved — counts, adjustments, transfers, and basic restock signals live in the admin now, and for a single-location store with forgiving suppliers that may honestly be enough. What you won't find there is Stocky's planning layer: demand-based suggestions, supplier records, and purchase orders as first-class documents. Free is a real price advantage; just be clear about which of your Stocky habits it doesn't cover before you commit to it.

And if your Stocky usage was heavy on purchase-order paperwork, a dedicated inventory app is genuinely the safer landing today — that category has spent years on exactly that workflow. The interesting question is what you pair the paperwork with.

Lumnya is your store’s digital workforce for Shopify: a customer-facing AI out front, and a back office of specialist agents behind it. One of those specialists — the Inventory Forecaster — is live today in private beta. It watches stock across your whole catalog on a schedule, flags products as critical or low the moment they cross thresholds you control, and opens priority-ranked reorder recommendations with the reasoning attached. Nothing executes silently: every action is confirm-gated and logged, and what you approve or reject is remembered, so the recommendations start from your preferences instead of from zero.

And here's the honest part: Lumnya does not do purchase orders or supplier records yet, and velocity-based stockout projections are in the works rather than in your hands. If you need a full PO workflow on September 1, pair a dedicated inventory app with us — or just use the dedicated app and come back when our roster covers you. We'd rather earn the switch than talk you into it early. If continuously watched inventory inside one accountable system sounds like the direction you want, the waitlist is open.

Migration takes weeks; your bestseller doesn't wait. This formula bridges the gap — it's the boring version of what Stocky's suggestions were doing for you:

Reorder point = (average daily sales × supplier lead time in days) + safety stock. For safety stock, a practical start is the gap between your busiest recent week and an average one: (peak daily sales − average daily sales) × lead time. When stock for a product touches its reorder point, you order.

Illustrative numbers, real method. Recompute the averages monthly — a reorder point set in July and never touched is how January stockouts happen. If a supplier's lead time swings, use its worst recent value rather than its average; safety stock exists for the bad month, not the typical one. This is also, frankly, a good test for any Stocky alternative you evaluate: if you can't see numbers like these behind its suggestions, you're being asked to trust a black box.

• Waiting for August. Every week of delay converts slack into pressure, and pressure into whatever tool had the best ad that day.
• Exporting data but not decisions. Write down why your min/max values were what they were — numbers without their reasoning don't transfer.
• Buying for the store you might become. An ERP because a second warehouse is possible next year is a complexity tax paid on a maybe.
• Forgetting the API blast radius. List everything that reads from Stocky — reports, spreadsheets, automations — and migrate those connections too.
• Skipping the parallel run. A forecast you never compared against your own instinct isn't a tool you chose; it's a black box you moved into.

However you land: export early, choose deliberately, and keep a reorder point running in the gap. The stores that come out of this migration stronger won't be the ones that picked fastest — they'll be the ones that knew exactly what they needed before anyone's pricing page told them.
