A staffing invoice adjustment or credit/debit memo should change the forecast only when the current source shows the affected invoice, adjustment type, amount, and status. Preserve the gross invoice, the separate adjustment, and the expected net settlement bridge. Do not silently overwrite the original invoice amount or assume every portal adjustment changes cash in the same direction.
SAP Fieldglass documentation distinguishes tax adjustments from non-tax adjustments and notes that non-tax adjustments can be credits or debits. Its adjustment-only credit/debit memo specification ties the memo to a valid invoice identifier and adjustment reason. Those fields provide the lineage a forecast reviewer needs.
Preserve the gross-to-net bridge
| Source item | Receivable treatment | Cash treatment | | --- | --- | --- | | Issued staffing invoice | Keep the supported gross open amount | Forecast only from current timing evidence | | Credit adjustment | Reduce the supported settlement or source balance when posted | Do not treat the reduction as cash received | | Debit adjustment | Add the supported amount when posted | Do not assume the added amount shares the old timing | | Adjustment pending approval | Keep as a separate unresolved item | Leave its timing effect unassigned | | Net receipt and remittance | Reconcile invoice plus adjustments | Count the observed cash once |
The accounting report and portal may present different stages. A portal adjustment can be proposed or approved before the exported receivables source changes. Keep both states visible instead of forcing them to agree prematurely.
Capture the adjustment evidence
For each item, record the original invoice ID, adjustment or memo ID, reason, tax or non-tax classification, credit or debit direction, amount, currency, approval status, effective date, source retrieval date, owner, and next review date. If the change relates to a time sheet, expense, fee, or tax difference, keep that reason as supplied rather than inventing a category.
Do not infer a recurring adjustment percentage from prior invoices. Current work orders, rate cards, buyer configurations, taxes, or approval outcomes can differ. Use the observed record for the specific invoice.
The staffing VMS status guide helps separate submission, approval, payment pending, and paid. The supplier-funded MSP fee bridge covers a related but narrower fee deduction.
Update the collection assumption separately
A posted credit may reduce the open balance without creating cash. A debit may increase the balance without proving the buyer will pay the incremental amount in the same week. After the source changes, re-evaluate timing using the buyer's current approval and payment evidence.
When cash arrives net of an adjustment, reconcile the gross invoice, memo, and receipt to the remittance. If the difference remains unexplained, use the short-payment framework rather than forcing the invoice closed.
Decision rule
Keep the original staffing invoice and every adjustment linked. Update the supported open amount from posted evidence, treat credits as amount changes rather than receipts, and assign cash timing only after the adjusted invoice has current payment support.
