Purchase order to invoice

Keep the purchase order, proof and approval ready before invoicing.

A purchase order may authorise the route, but it does not by itself prove the service, record acceptance or satisfy the buyer's submission instructions. Stellvia is being built to prepare those supplier-side facts before accounting.

Supplier-side readiness

Five distinct facts carry the route forward.

Keep the live instruction, completed-service evidence, authorised acceptance, prescribed package and submission acknowledgement connected without treating any one of them as a substitute for the others.

  1. 01

    Live instruction

    confirm the buyer, supplier, scope, order reference, value or limits and applicable service period from the retained source.

  2. 02

    Service evidence

    retain the records that demonstrate what was delivered, where, when and by whom.

  3. 03

    Authorised acceptance

    distinguish a buyer decision from delivery evidence or an informal acknowledgement.

  4. 04

    Prescribed package

    prepare the required references, forms, supporting documents and current versions.

  5. 05

    Submission state

    keep the required portal or channel, submission event and acknowledgement distinct from invoice issue.

Primary sources

What published evidence shows.

Official and enterprise guidance shows that service entry, supplier rules, invoice particulars and submission routes can remain separate requirements. These sources explain external processes; they are not customer evidence or proof of Stellvia's product operation.

Stellvia is not purchasing software. Its proposed role begins with the supplier's verified sources and prepares the route after work and before accounting; it does not issue purchase orders, approve on a buyer's behalf or guarantee invoice acceptance.
