Stocky alternative for average unit cost: keeping weighted average cost after Stocky

Updated 28 October 2026 · By Senoussi, developer of True COGS at Nexus Logic Systems

28 October 2026: about a month left to export. Shopify promised read-only access to Stocky for at least 90 days after 31 August 2026, which reaches 29 November 2026. Shopify has not named a closing date, so download your completed purchase order reports, your stocktake history and your historical cost data now. What to export.

Short answer

Stocky stopped on 31 August 2026, and with it the average unit cost it recalculated on every received purchase order. Shopify's own inventory tools keep one fixed Cost per item and Shopify recommends a third-party app for weighted-average costing. Export your completed purchase orders and historical cost data while Shopify's read-only window lasts (at least 90 days after 31 August, so until at least 29 November 2026), then move to an app that recalculates the average on each delivery. True COGS does this and can import your Stocky purchase orders with their original dates.

What Stocky's average unit cost did

Stocky defined average unit cost as the average cost of your current stock and updated it every time you received a purchase order, weighting the current average and the received landed cost by quantity. Shopify's example: 30 units at $10.00 plus 15 received at $8.00 gives $9.33. With automatic syncing turned on, Stocky overwrote Shopify's Cost per item with that average (Shopify Help).

What Shopify offers now

Stocky is no longer available as of August 31, 2026. It was delisted from the Shopify App Store on February 2, 2026, so you can't reinstall Stocky.
Shopify's built-in inventory does not calculate weighted-average costing; each variant's cost stays fixed when you receive a purchase order or transfer.
For weighted-average costing or landed cost allocation, Shopify points to a third-party inventory app.
Historical purchase orders can't be imported into Shopify, and suppliers can't be exported from Stocky.

All five points are from Shopify's guide Migrating from Stocky to Shopify inventory management.

Stocky alternatives, by the job Stocky did

Stocky did several jobs: purchase orders, stock counts, reorder suggestions, and the average unit cost. Since 31 August Shopify's admin does most of the first three; the average cost is the job it leaves to apps. No single app below does everything Stocky did, so choose by the job you miss most.

Disclosure: this page is published by Nexus Logic Systems, the developer of True COGS. The other rows come from each app's Shopify App Store listing and help pages, read on 21 October 2026, and can change.

Option	Purchase orders	Stock counts	Forecasting	Average cost written to Cost per item	Landed cost	Price
Shopify admin (built in)	Yes: create, receive	Yes	Sidekick suggestions	No: one fixed cost per variant	Cost adjustments on the transfer, not in Cost per item	Included
Prediko	Yes	Yes (stock take)	Yes	Daily sync: last price, weighted average or FIFO; off by default	Not stated	From $49/month
Landara	Yes	Yes (25 lines on Free)	Not stated	FIFO; average on paid plans; writing to Cost per item not stated	Yes: freight, duty and FX, read from invoices	Free plan; from $49/month
True COGS (ours)	Receives Shopify's purchase orders; does not create them	No	No	Yes, on each receipt: weighted average, FIFO on paid plans	Yes, on paid plans	Free up to 25 variants; from $29/month

If you miss Stocky's counts and reorder tools, Shopify's admin may now be enough on its own, with an app beside it for the cost. If you miss the average unit cost, you need an app that recalculates it on each delivery and writes it to Cost per item, because Shopify's own reports read that field.

Export before the read-only window closes

Shopify gives read-only access to export your data for at least 90 days after 31 August 2026. Ninety days after 31 August is 29 November 2026. Shopify calls that a minimum, so don't wait for it.

Export all completed purchase order reports as CSV files. These carry what you paid, by date, and they are what rebuilds your cost history.
Export your historical cost data from Stocky's reports.
Export your stocktake history. Shopify lists it with the purchase orders and cost data as records to keep.
Write down your suppliers by hand; Shopify says they can't be exported.
Keep the files somewhere other than your downloads folder. Your accountant may need them for this year's closing stock.

Moving your costs to True COGS

Install True COGS. It takes a snapshot of the Cost per item you have today.
Import your Stocky purchase order CSVs. Each line goes in with its original date, so your cost history starts where Stocky's did, not on the day you installed.
From then on, receive purchase orders in Shopify as usual. Each one updates the weighted average for the units received and writes it to Cost per item, the job Stocky's sync used to do. This works on the free plan for up to 25 variants with a cost on record.
If you paid freight or duty, add it to the delivery so it is part of the cost (paid plans; see landed cost per unit).

What True COGS does not replace

True COGS replaces the costing part of Stocky: average cost on receipt, cost history and stock value at cost. It is not a full replacement for Stocky's stock-control tools such as stocktakes. If you used those, keep a stock-control app beside it; True COGS works on whatever Shopify receives.

Questions merchants ask

What are the alternatives to Stocky?

For purchase orders, stock counts and transfers, Shopify's own admin now covers most of what Stocky did. For the average unit cost, which Shopify does not calculate, you need an app: True COGS writes the weighted average to Cost per item on each delivery; Prediko can sync last price, weighted average or FIFO once a day; Landara costs sales by FIFO with landed cost.

When did Stocky shut down?

Shopify says Stocky is no longer available as of August 31, 2026, with read-only access to export data for at least 90 days after that date.

Can I still export my Stocky data?

Yes, during the read-only window: at least 90 days after 31 August 2026, which is at least until 29 November 2026. Export completed purchase order reports as CSV and your historical cost data.

Does Shopify replace Stocky's average unit cost?

No. Shopify's guide says its built-in system does not calculate weighted-average costing and recommends a third-party inventory app.

Can I import Stocky purchase orders into Shopify?

Shopify says historical purchase orders can't be imported into Shopify. True COGS can import the CSV exports as dated cost history.

What is the best replacement for Stocky's average unit cost?

An app that recalculates the average on every received purchase order and writes it to Cost per item. True COGS does that and imports Stocky purchase orders with their dates. See how the options compare.
