Product/Purchase orders

Commit cost, connected.

Raise purchase orders against the budget with your supplier terms applied automatically, so every order goes out consistent and correctly coded. Commit cost that updates the cost report instantly, and match supplier invoices back to the PO.

Centralised terms and suppliers, so every purchase order goes out the same.

01 · Raise

Raise the PO against the budget.

Every purchase order is written against a budget line item and cost code, so the money is coded the moment it’s committed, not reconciled weeks later. No loose orders, no uncoded spend.
