Purchase orders
A PO is the spend check you already have.
In short
Purchases → Purchase Orders records what you intend to buy. There is no multi-step approval matrix. Convert to bill when the supplier invoice arrives — that conversion locks the PO so it cannot be quietly edited.

FAQ
Common questions
Can I set a £5,000 approval limit?

Is there an approval inbox?
No.
Which plan includes POs?
Business and above.
Can I still change a billed PO?
