Month-End Close Checklist for B2B Payments

Take a consistent snapshot

Set the close date and note the reporting time zones. Export the open invoice list, transaction and funding reports, credits, and unresolved exceptions for the same period. Record which system provided each export and who checked it.

Reconcile what changed during the month

• Tie invoice payments and credits back to the buyer and source references.
• Match gateway settlements and bank deposits, then list deposits in transit separately.
• Carry forward unexplained adjustments and unpaid balances with an owner and expected resolution date.

Retain the evidence for a later question

Keep a summary of totals, documented adjustments, and signed-off exceptions alongside the exports. Preserve the cutoff and allocation method. If an item is resolved after close, record the resolution date and supporting transaction in the next reporting cycle according to your team’s procedures.
