3 · Purchase orders and confirmation

Who acts: the supplier. Starts with: a purchase order (PO) arriving in the supplier's queue. Ends with: the supplier committing to all of it, part of it, or none of it.

One PO per supplier

Issuing a request creates one purchase order for each supplier in the plan. Each PO is its own contract, with its own lines, total, delivery or pickup, and payment method. A request for five suppliers produces five POs that move independently.

Confirming

The supplier checks stock and prices, then answers line by line:

Answer for a line	Meaning
In full	Will supply the quantity ordered at the price ordered
Part only	Can supply fewer
Later date	Can supply it, but not by the date needed
Substitute	Proposes an equivalent product, with its price
Can't supply	Drops the line

The supplier also confirms the delivery window or pickup point. By default the supplier has 4 hours to confirm; a late confirmation is flagged to platform staff.

Statuses you will see

PO issued → Awaiting confirmation → one of:

Outcome	Status	What happens next
Everything as ordered	Confirmed	On to payment
Some lines changed	Partially confirmed with Correction proposed	The buyer answers the correction before the order moves on
Nothing can be supplied	Rejected	The buyer sources those lines elsewhere

Before the supplier confirms, the buyer can still cancel the PO.

Why changes become a correction

The buyer ordered something specific. If the supplier can only offer something different, the buyer decides whether to take it. So every difference — quantity, price, date, substitute — is collected into one correction. The buyer accepts, counters or rejects it, and only then does the PO move on as a new version.
