Case File 020: The Unapplied Cash Mystery — When Payments Don’t Count

Filed under: A/R Illusions & Misapplied Money

The client was puzzled. “We got paid. Why does the invoice still show open?” Detective Debit squinted at the A/R Aging Summary, her bowl of pumpkin ice cream was melting.

Figgy, her ever-watchful canine shadow, stirred from her nap as the scent of mystery thickened.

There it was: a payment sitting quietly in the ledger… but not linked to anything. “Unapplied cash,” she muttered. “The ghost of bookkeeping past. Like a turkey wandering through the ledger with no destination.”

The Clues

  • Payments recorded but not linked to specific invoices

  • A/R Aging Summary showing open balances that shouldn’t exist

  • Duplicate follow-ups sent to clients who already paid

  • Income reports that don’t match cash flow

The Twist

This isn’t a missing payment—it’s a missing connection. When payments are entered without being applied to an invoice, QuickBooks holds them in limbo. They don’t reduce A/R, they don’t close the invoice, and they don’t show up where they should. It’s like paying a bill and forgetting to tell the system.

Detective Debit’s fix? Match every payment to its rightful invoice. And if the invoice is missing? Time to investigate what really happened.

The Takeaway

Always apply payments to open invoices—not just to the customer. Review your Unapplied Cash Payment Income report regularly, and don’t let payments float in the void. Clean books require clean links.
