Cash Posting
Cash posting, also called cash application, is the process of recording an incoming payment and applying it to the correct invoice(s) and customer account. In factoring and asset-based lending it is the step that turns a raw bank deposit into an accurate, invoice-level update of what has been collected and what is still outstanding.
What is cash posting?
Cash posting (or cash application) is the act of matching money received to the open receivables it pays down. A payment arrives by check, ACH, or wire, and someone has to decide which account debtor sent it, which invoice or invoices it covers, and how much of each invoice is now satisfied. Until a payment is posted, the ledger overstates what is still owed and the collateral position is out of date.
In commercial lending the stakes are higher than in ordinary corporate accounts receivable. Posted cash drives the availability calculation, the reserve release back to the client, and the figures that feed each borrowing base certificate. Misposted cash can inflate availability or hide a slow-paying debtor.
How cash posting works
A typical flow runs in a few steps:
- Capture the payment and its remittance detail (the breakdown of which invoices the payer intends to cover).
- Identify the paying account debtor and tie the funds to the right client.
- Match the amount to one or more open invoices.
- Post the application, release or adjust the related reserve, and update the aging.
Where funds land through a lockbox, the bank file supplies the deposit data but rarely resolves the matching by itself. Remittance advice often arrives separately, by email or portal, so the deposit and its explanation must be reunited before anything can post cleanly.
Why cash posting is hard
The difficulty is rarely the easy case of one payment for one invoice. The hard cases dominate:
- Lump-sum payments. A single check or ACH settles dozens of invoices with no clean per-invoice split.
- Partial payments. The amount does not equal any invoice total, leaving an open balance that must be tracked.
- Short pays. The debtor deducts for a dispute, discount, or chargeback, and the gap has to be coded rather than left dangling.
- Vague or missing references. No invoice number, a stale purchase-order number, or a debtor name that does not match the system spelling.
- Unapplied cash. Funds that cannot be matched sit in suspense, distorting both the aging and the picture of true collections.
Each unresolved item is a small data-quality problem that compounds. Left alone, unapplied cash and miscoded short pays drift into the next period and corrupt downstream metrics such as days sales outstanding and dilution.
Relation to reconciliation
Cash posting and reconciliation are adjacent but distinct. Posting applies each payment to invoices in real time; reconciliation periodically confirms that the sum of posted activity agrees with the bank, the borrowing base, and the client's own ledger. Clean posting makes accounts receivable reconciliation fast; sloppy posting forces the reconciliation step to chase suspense balances and undo errors after the fact.
Accurate, timely cash posting is also a quiet control against fraud and over-advance: it surfaces payments that do not correspond to any verified invoice and keeps eligible collateral honest.
Automating cash posting
Because most of the work is pattern matching across messy inputs, cash posting is a strong candidate for automation. Zolvo helps lenders and factors match remittances to invoices and keep reconciliation current, reducing the volume of unapplied cash that has to be worked by hand.
