HOW-TO

How to stop paying a vendor bill twice in NetSuite

Short answer

Before you enter a vendor bill in NetSuite, search the vendor's bills for the same number or amount. Use one reference format and check the bill payment batch for repeats.

Last checked

Duplicate payment is when the same supplier invoice is entered or paid more than once. It often happens when an invoice arrives by two routes.

Before you start

  • Reference No. filled on every bill

The NetSuite way

Where to find it: Transactions > Payables > Enter Bills > Reference No.

  1. Enter the supplier invoice number in Reference No.
  2. If it matches another bill for the same vendor, NetSuite may show a warning on save. Click Cancel to enter a different number or OK to save.
  3. Run a saved search on Vendor Bill by Vendor and Reference No. to find repeats.

Limits in NetSuite

  • The Reference No. warning can be bypassed with OK.
  • Warn and Block (Setup > Accounting > Preferences > Accounting Preferences, Items/Transactions subtab) stops the save on a repeated document number for vendor bills. It works on the document number.

The Pulsify way

  1. Forward the supplier's invoice to Pulsify.
  2. Pulsify compares the invoice number with punctuation and case ignored, plus the same vendor, invoice date or tax ID.
  3. It checks other Pulsify documents and active bills in NetSuite.
  4. A possible duplicate is flagged. Open the match, then reject or approve anyway.

What Pulsify does not do here

  • Pulsify flags. You decide.
  • A duplicate with a quite different invoice number may not be found.

Common mistakes

  • Leaving Reference No. blank, so there is no invoice number to compare.
  • Clicking OK on the warning without opening the first bill.

Common questions

Does NetSuite warn about a repeated invoice number?

It may. If the Reference No. matches another bill for the same vendor, NetSuite may show a warning on save. Click Cancel to enter a different number or OK to save.

Can NetSuite block a duplicate bill?

Yes. Set Duplicate Number Warnings to Warn and Block at Setup > Accounting > Preferences > Accounting Preferences, on the Items/Transactions subtab. NetSuite then makes the user change the document number before a vendor bill can be saved. The Reference No. warning alone can be bypassed.

How do I find repeats that are already saved?

Run a saved search on Vendor Bill by Vendor and Reference No. Any vendor and number that appears twice needs a look.

What does Pulsify check?

The invoice number with punctuation and case ignored, plus the same supplier, invoice date or tax ID.
