Order & Invoice Processing for Promotional-Products and B2B Shops
Exception Handling No. 1

A missing PO number needs a traceable correction process.

This page gives an overview of order intake, invoices and queries. A missing purchase order reference is checked with the client. Document status, the permitted correction procedure and approval are reviewed before a change; posted documents are not silently overwritten. Order-to-Cash explains the full process.

A missing PO number needs a traceable correction process.
Example workflow

Delivery is correct. The invoice lacks its purchase reference.

An order is complete, but the recipient cannot assign the invoice. Check the required reference when the order arrives. If a correction is needed later, keep it connected to the order and original document instead of creating an unrelated second invoice.

  1. 1

    Check complete inputs

    Review invoice recipient, purchase reference and agreed terms together. Resolve missing data before creating the document.

  2. 2

    Match document and service

    Compare lines and quantities with the confirmed service. Keep partial transactions traceable to the full order.

  3. 3

    Complete the correction

    Document the agreed correction process and inform the responsible recipient. Keep the original transaction accessible.

Scope of services

Five document types, one system.

The commercial processing of a promotional-products shop is form-driven and repeats daily. That is exactly why, at PROWERB, it's set up as a standard process — not as exception handling.

01Order intake & confirmationEvery shop order is accepted, checked against inventory and confirmed. Changes and cancellations are handled within the same process.
02Invoice →Invoicing from the same system that also manages orders and dispatch — with the order reference from the customer's procurement system on the document.
03Invoice correction →Missing or subsequently supplied PO numbers are added as a standard notification process, and the invoice is reissued corrected.
04Credit noteCredit note requests — for example due to returns or quantity discrepancies — are booked against the original document and remain fully traceable.
05Catalog order filesBulk orders arrive as a standardized file, are imported, checked and booked as individual orders — one transmission channel for many line items.
Five document types, one system.
Process

From the shop order to the closed document.

The steps connect order status, goods handling and documents. Errors and change requests are clarified with the responsible party before completion.

  1. 01

    01 · Order intake

    Order from the customer shop or via a catalog order file — with automatic inventory check in the ERP.

  2. 02

    02 · Confirmation

    Order confirmation sent to the orderer. Changes and cancellations run through the same process, not a second ticket.

  3. 03

    03 · Fulfillment

    Picking, packing, dispatch from our own warehouse — every movement booked in real time.

  4. 04

    04 · Invoice

    Invoicing with PO reference, consistent with the order and delivery, because all three come from the same data set.

  5. 05

    05 · Correction & credit note

    Invoice corrections and credit notes as standard notification processes — against the original document, with no search effort.

What this shows

Connected from order to document.

The visual orders recurring process steps. The important part is continuous booking without a manual handover.

System operations

Shared references enable reconciliation.

Order, stock movement and document are reconciled through shared references. Missing data or conflicting quantities enter an exception process with a responsible owner. Customer systems and accounting may be involved; data exchange and acknowledgements are agreed accordingly.

Proven

For us, ongoing operation is the normal case, not an afterthought.

Order and invoice processing is rarely spectacular — and that's exactly how it should be measured: by accounts that run cleanly for years.

Full operation of the promotional-products shop with several thousand transactions — strongly form- and standard-process-driven, including catalog order files as bulk submissions and many document corrections. The most frequent: adding the PO number.

FAQ

Frequently asked questions about order and invoice processing.

Why are PO numbers missing from invoices in the first place?

Because the order reference in the customer's procurement system is often only generated after the shop order is placed. PROWERB handles the follow-up submission as a standard process: the PO number is added and the invoice is reissued corrected.

Can orders still be changed or cancelled after intake?

Yes. Changes and cancellations are documented standard transactions and are handled within the same order — depending on how far picking has progressed.

How do bulk orders work?

Via catalog order files: a standardized file that is imported, checked and booked as individual orders. This is the usual route when many line items arrive at once.

Does PROWERB connect to our procurement system or ERP?

The MEP platform connects existing shops, ERP and WMS systems. The transmission channels range from structured file exchange to direct integration, depending on the customer — the right approach is defined during onboarding.

Who is the dedicated contact for commercial exception handling?

Account management operates on three levels: key account management as the strategic point of contact, campaign steering for campaigns, and the fulfillment team for operational matters, IT and dispatching. Commercial exception handling lands wherever the document is managed.
