Agency pass-through or reimbursable costs should not enter an accounts receivable forecast before the client invoice is issued. The cost may be billable and operationally important, but it remains billing backlog until a posted invoice creates an open customer balance.
Separate cost, billable item, and receivable
Intuit documents a workflow for marking expenses billable and adding them to a customer invoice. It also describes delayed charges as non-posting transactions that can be added to an invoice later. Both sources support the same boundary: the upstream billing record is not yet open AR.
| Stage | What the record supports | Forecast treatment | | --- | --- | --- | | Agency incurs cost | Cash outflow or payable evidence may exist | Keep outside customer AR. | | Cost is marked billable or held as a delayed charge | Future client billing is expected | Put in a billing-readiness queue. | | Client invoice is issued | A posted receivable exists | Reconcile the open balance into AR. | | Client payment is recorded | Receipt evidence exists | Reduce AR and handle cash cutoff separately. |
The billable-expenses guide provides the broader professional-services boundary. This page focuses on agency pass-through items and the handoff into an invoice.
Build a billing-readiness control
For each reimbursable item, preserve the client, source vendor or cost record, service or campaign period, amount, contractual billing basis supplied by the business, approval status, invoice owner, and target billing date. Do not treat the target date as a collection date.
Before moving the amount into AR, confirm that the cost was included once on an issued invoice. Link the source item to the invoice ID and reconcile the invoiced amount. If several costs are bundled into one invoice, preserve the many-to-one relationship. If a cost remains unbilled, keep it out of the open-invoice total.
The agency invoice-approval guide can help classify approval or milestone blockers before issuance.
Avoid margin and cash confusion
Reimbursement changes several views differently. The agency may already have paid the vendor, may expect to bill the client, and may later collect the invoice. Those events should not be collapsed into one date. An AR collections forecast addresses the last event only after an invoice exists; it does not replace a complete cash forecast or profitability view.
Do not assume every pass-through cost is reimbursable, apply a markup, or state a collection date without source evidence. Those depend on the actual client agreement and billing record.
Decision rule
Keep reimbursable agency costs in billing backlog until they appear once on a posted client invoice. Then forecast the reconciled open balance from invoice-level timing evidence.
