Separate agency media spend from client pass-through billing

Media platforms, agency cards, and client invoices operate on different calendars. The reconciliation should follow each campaign without treating timing as earned margin.

A usable agency media-spend pass-throughs file identifies the entity, period, currency, source systems, cutoff, preparer, and reviewer. Those details sound routine. They are also what let someone reopen the file next month without relying on memory.

Export every in-scope record before filtering. Save the report name, filters, extraction time, row count, and amount total. Compare that population with the prior open-item list and note any account, location, channel, or job that is missing.

Work from the saved source population, then investigate exceptions. Do not edit the original export to make the schedule tie.

Collect the client authorization, platform export, vendor invoice, campaign ledger, client billing, and payment proof. Assign each item a short reference and capture its source, date, amount, currency, status, and owner. Label a missing record as missing. A guess, an estimate, or an unapproved chat screenshot does not replace it.

Start with the last reviewed balance or status. Show additions, applications, releases, refunds, transfers, and corrections on separate lines. Tie the result to the current ledger or operating report. Gross movement often exposes two offsetting mistakes that a net total hides.

Use plain labels: missing record, timing difference, amount mismatch, duplicate, stale item, or judgment question. Add an owner, requested action, due date, age, and known financial effect. Close the item only when the stated evidence or approval arrives. If it remains open at cutoff, carry it forward visibly.

The preparer can compare observable fields, check arithmetic, and draft a focused question. The preparer should not decide principal-agent presentation, markup, and contract interpretation. Send that question to the agency finance owner with the evidence reference, the amount involved, and the response date needed. Save the answer in the workpaper rather than leaving it in a private message.

Reperform large entries, manual adjustments, old exceptions, and records whose status changed. Trace some items from source to schedule and others from schedule back to source. A repeated mismatch may point to a weak written procedure, a stale mapping, or a missing system feed. Record what you observed without guessing at the cause.

The final packet should include the untouched exports, reconciliation, evidence index, exception queue, approval record, and a short status note. State what tied, what did not, who owns the next action, and which decisions remain open. That is enough for the reviewer to continue the work without reconstructing it.
