Here's exactly what Posto uses from your Shopify store, what it never touches, where your data lives, and what happens if you leave.
Start 30 days freePosto uses your products, stock levels, and order quantities to forecast. It never reads who your customers are or how they paid. It only changes your store when you record stock arriving, and it only emails a supplier when you tell it to.
Your products, inventory levels, locations, and each order's date and quantities. That's what it needs to forecast demand.
Customer names, email addresses, shipping addresses, and payment details. None of it is read or stored.
Inventory counts, and only when you record stock received on a purchase order. Posto confirms the units and the location first. If you turn it on in Settings, Posto also updates the cost per item of the products you receive. Importing purchase orders never changes anything in Shopify.
Only when you choose to email them a purchase order, after you've reviewed the email. It carries your store's name, and replies go to your store's contact email.
No. You're billed through Shopify, on your regular Shopify bill, and you pick, change, or cancel your plan on Shopify's own plan page.
Posto runs on Railway for app hosting, Supabase for its database, and Postmark to send purchase order and alert emails. All three are US-based.
Yes. Your data is always yours. Export everything Posto stores for your store at any time, as one zip of spreadsheets with a README that explains each file. If you uninstall, Shopify cancels your subscription, and Posto deletes your store's data about 48 hours later. It keeps only a scrambled marker recording that your store has used its free trial.
Install Posto, bring your suppliers and costs over, and send your first purchase order. 30 days free, everything unlocked, no payment details.
