Supplywren: purchase orders and reorder for Shopify
For shops that buy what they sell from suppliers. Know what to reorder and why, send purchase orders, receive deliveries box by box, and keep Shopify's cost per item right.
What it does
- Reorder suggestions: how fast each product sells, the supplier's lead time plus your safety days, and how many days each order should cover. Then the supplier's minimum and case pack. Every suggestion shows those steps in plain words.
- Purchase orders: one click turns suggestions into a draft per supplier. Send it as a PDF, a CSV or an email draft, and the quantities show as Incoming on your products in Shopify.
- Receiving: receive as many deliveries as arrive, scan barcodes, record damaged units (kept out of stock), print shelf labels, and undo a delivery if you made a mistake.
- Invoice check: ordered vs invoiced vs received for every line, the credit to ask for, and missing units carried to a new purchase order.
- Landed and average cost: shipping, duties and fees spread over the order, averaged with the stock you have, and written to Shopify's Cost per item with a full cost history.
- Imports and locations: suppliers, supplier price lists and past purchase orders from CSV (matched by SKU or barcode), and reorder and receiving per location.
Coming from Stocky?
Shopify's Stocky app stopped working on August 31, 2026. Supplywren covers the receiving-and-reorder side it handled: purchase orders with partial receiving, supplier SKUs and case packs, Incoming stock, PO files and labels. It adds lead-time reorder math, the invoice check and landed cost. Import your Stocky purchase-order export on the Import page; suppliers are built from the names in it and from your products' Vendor field.
Plans
Free for 3 suppliers, 10 purchase orders a month and 1 location, with reorder suggestions, partial receiving, Incoming, PDF/CSV and imports. Starter is $9 a month (unlimited suppliers and purchase orders, shelf labels), Pro $19 (invoice check, back-order carry-over, landed and average cost, 3 locations) and Plus $29 (every location), or 2 months free yearly. 14-day free trial on paid plans. Billed by Shopify; a limit never stops you receiving an open order, and moving down a plan deletes nothing.
Private by design
Supplywren never stores a buyer's name, email or address; it asks Shopify to leave them out of the order data it receives, and keeps only how many of each product sold each day. No analytics, tracking or ads. Read the privacy policy and terms.
