One of the oldest tricks in retail happens right after a customer pays cash and walks out the door: a staff member opens the POS, voids or deletes the invoice, pockets the cash, and leaves you with unexplained inventory shortages at the end of the month.

5 Warning Signs Your Current POS Is Costing You Money

  1. Completed invoices can be deleted or edited without the owner’s approval.
  2. Document numbers have mysterious gaps (e.g., Invoice #0041 jumps to #0043).
  3. Voided items don’t automatically put the exact 15-digit IMEI back into available branch stock.
  4. You only discover voided transactions at the end of the day—or not at all.
  5. Once a record is voided or deleted, you can no longer view what items and discounts were originally on it.

How FoneShop’s Admin-Approved Void Workflow Works

We designed FoneShop so that your cashiers can work fast while your revenue stays completely protected:

  • Gap-Free Document Numbers: Every Sales Invoice (INV-), Official Receipt (OR-), and Void Document (VOID-) is numbered sequentially with zero gaps.
  • Request → Admin Approval: If a legitimate mistake happens at the counter, the cashier submits a Void Request with a mandatory reason. The Admin receives an instant notification badge and can review the full invoice before approving or rejecting the void.
  • Automatic Stock & IMEI Restoration: The moment an Admin approves a void, FoneShop automatically returns the exact product quantities and 15-digit IMEIs back to branch stock and updates customer balances.
  • Permanent Audit History: Even after a transaction is voided, the original invoice and receipts are preserved in FoneShop’s Voided & Deleted Record Viewer so you always have a complete paper trail.
