how to handle partial shipments and partial invoices

TL;DR

Partial fulfillment is normal: track PO lines by remaining open quantity, match each partial invoice against cumulative receipts, and close PO lines only when fully received and billed. Keep a running ledger per PO line so the fifth partial invoice still matches correctly.

Steps

1. Maintain open quantity per PO line: ordered minus received. Expected: A live ledger.

2. Match each partial invoice against cumulative receipts for its lines. Expected: Correct partial matching.

3. Update open quantities after each match. Expected: The ledger stays current.

4. Close PO lines when received and billed quantities agree. Expected: Clean PO hygiene.

5. Flag invoices that exceed remaining open quantity. Expected: Overbilling caught on partials too.

When to use

• Split deliveries
• Progress billing
• Blanket order releases

When not to use

• Single complete shipments
• Service contracts
• Non-PO invoices

Compatibility

ERP-agnostic.

Root cause

POs describe a total commitment fulfilled over time. Matching must be cumulative and line-level, or later partials match against already-consumed quantities.

Edge cases

• Final partials often include adjustments; expect variance on the last one
• Substitutions across lines need buyer approval before matching
• Retainage on progress billing is a separate hold, not a mismatch
