Where ordering goes wrong

Most order mistakes happen after you've decided what to buy: a quantity copied wrong, a case pack forgotten, a minimum missed, or an email that never got a reply.

Then the delivery arrives in pieces, and someone has to remember what's still coming. Shopify's admin can create purchase orders, but it can't email them to your supplier, and your suppliers' lead times, minimums, and case packs aren't used when an order is worked out.

Posto keeps the whole order in one place, from the recommendation to the last box received.

From recommendation to received

1

Draft

Pick the products to reorder, and Posto groups them into one draft per supplier, with quantities rounded to each supplier's minimum and case pack. Change anything you like.

2

Send

Review the email and send it with the PDF attached. Posto fills in the expected arrival date from the supplier's lead time. If something changes, edit or cancel the order and email the update.

3

Receive

Record what arrived, all at once or line by line, at the location you choose, and Posto adds those units to your Shopify stock. Over-deliveries are recorded with a warning, and partial deliveries stay open until everything arrives or you close the order short.

Orders that run late show up as overdue.Stock on order counts in every recommendation.Past orders import from a spreadsheet or Stocky export.

Questions about purchase orders

How is this different from Shopify's built-in purchase orders?+

Shopify's purchase orders record and receive orders well. Shopify's own migration guide says you can't email one to your supplier (you download the PDF and send it yourself), supplier lead times, minimums, and case packs aren't used in purchase order calculations, and cost per item stays fixed when stock arrives. Posto emails the order, rounds it to each supplier's rules, and works out a landed cost per unit. Our Posto vs. Shopify purchase orders comparison covers where each fits.

Who does the email come from?+

It carries your store's name, and when your supplier replies, the reply goes to your store's contact email.

Can I change an order after I've sent it?+

Yes. Edit or cancel a sent order and email the update to your supplier from Posto.

Does Posto see the purchase orders I made in Shopify?+

No. Posto keeps its own purchase orders. Pick one place for orders so you don't track the same order twice.

When does receiving change my Shopify stock?+

Only when you record stock received. Posto confirms the units and the location first, and only the units that arrived are added.
