Your supplier is probably on Shopify too. So why are you emailing them a PDF?

Millions of stores run on Shopify - and a growing share of them are wholesalers, makers and distributors selling to other businesses. Which means there’s a decent chance the supplier you restock from runs their operation on the same platform you do. And yet the purchase order that travels between you is a PDF in an email, exactly the way it would have been faxed in 1995.

The round trip a PO makes today

Follow one order from end to end and count the manual steps:

You build the PO - products, quantities, costs - and email it as a PDF.
Someone on their side re-types it into their system. For a Shopify-based supplier, that means keying your lines into an order by hand, matching your SKUs to theirs from memory.
Confirmation happens by email, if it happens. So does every follow-up: “did you get our order?”, “when does it ship?”, “was the blue one substituted?”
They ship, and the tracking number lives in an email thread, not on the order.
You receive, checking cartons against a PDF and typing quantities back into your own system.

Every hop is a place where a digit gets transposed, a line gets missed, or a day gets lost waiting on a reply. Neither side is doing anything wrong - the medium is the problem. Two structured systems are talking to each other through a document designed for printing.

What connected purchasing changes for the buyer

With Stockroom Network, you and a supplier who both run Stockroom connect once - and the PO stops being a document and becomes data:

You order exactly the way you already do. Build the PO, mark it ordered. Instead of landing in an inbox, it lands in your supplier’s Stockroom with every line matched to their catalog by the supplier SKUs you already keep.
The status moves itself. When they fulfill, their shipped quantities and tracking flow back onto your PO and walk it through ordered, partial and received - no typing, no chasing.
Your costs stay current. A connected supplier can publish the prices they charge you, so the costs behind your margins and reorder planning stop being a stale spreadsheet.

What it changes for your supplier

The supplier’s side of a PDF purchase order is quietly worse than the buyer’s - they’re the ones doing the re-keying. Connected, that work disappears:

Orders arrive structured, matched to their products, with quantities and requested dates already in place - not as an attachment to interpret.
One click creates the order in their store. Or automatically, if they turn that on - how incoming orders are handled is always the supplier’s setting, not the buyer’s.
Fulfillment is the update. Shipping the order is what tells the buyer it shipped - the confirmation emails write themselves out of the process.
It costs them nothing. Stockroom is free, so accepting a connection doesn’t mean buying software to please a customer.

If you’re a supplier holding a PO from a Stockroom store right now, there’s a page for you.

What crosses the connection - and what never does

Connecting two businesses’ systems should make both of them nervous until the boundaries are explicit. So they’re explicit:

Both sides approve the connection before anything crosses. The buyer consents when inviting; the supplier consents when accepting.
What crosses is exactly the purchase orders the buyer sends that supplier - lines, quantities, the buyer’s costs on those orders - plus the buyer’s business contact details so the supplier can set them up as a customer.
Nothing else does. Not the buyer’s sales or stock levels, not their other suppliers, not either store’s customer data. The supplier’s own costs never cross in any direction - only the prices they choose to publish.
Either side can disconnect at any time, immediately. Orders already shared stay where they are, because they’re that side’s business records.

If your supplier isn’t on Shopify (yet)

Nothing breaks. The PDF-and-email flow keeps working exactly as it does today - the network is additive, not a requirement. Stockroom even gives you a hint about which of your suppliers look like they’re on Shopify, so you know who’s worth inviting first.

But the next time you email a PO and picture someone on the other end re-typing it into the same platform you just exported it from - that’s the fax machine talking. There’s a better wire.
