# Duplicate invoice checks in Sage X3 for manufacturers

Sage X3 covers part of duplicate invoice checks on its own. Month-end volume hides duplicates. A bill sent twice in the last week is easy to approve twice.

## Why it matters for manufacturers

- Plants may receive the same invoice by email, post and portal. Each plant may then enter it.
- Recurring bills such as gas rental and maintenance contracts have the same amount each month, so a repeat looks normal.

## For manufacturers in Sage X3

- Direct invoices with no order go through Supplier BP invoices, where the Source document field holds the supplier's invoice reference. The help describes the same number check on Purchase invoices, so fill the field in every time.
- The Internal reference field on a purchase invoice takes a free number such as a counter number assigned when the invoice arrives. It sits beside the Supplier doc no. check.

## Rules that matter for manufacturers in Sage X3

- Sage X3 refers to the ABN per company or site. With several ABNs, run the GST report once per ABN, so a bill keyed into the wrong company lands in the wrong BAS.
- A valid tax invoice is the base for the GST credit. A bill with no tax invoice waits for the next BAS.
- Use Internal reference for your own counter number. It sits beside the supplier's number and does not replace it.

## What Sage X3 does on its own

On a purchase invoice you enter the supplier invoice number in the Supplier doc no. field (BPRVCR). X3 checks that the same number is not entered twice for the same invoicing supplier. The v12 help does not say whether it warns or blocks.

- Check is by number and supplier only.

The check is by supplier and number, not amount.

## Example

Example Tooling Supplies sends invoice T-5521 for $6,200 ex GST. The buyer enters it on a Purchase invoice with a purchase order. Accounts enters the same invoice on a Supplier BP invoice.

- Purchase invoice, Supplier doc no. T-5521: $6,200.00 (Accepted)
- Second purchase invoice, Supplier doc no. T-5521: $6,200.00 (Blocked, because the number exists for the same invoicing supplier)
- Supplier BP invoice, Source document T-5521: $6,200.00 (The help describes no same number check on this screen. Search BPRVCR first)

The Purchase invoice route stops the repeat. The Supplier BP invoice route relies on a search with Advanced Selection on BPRVCR.

## Common mistakes

- Leaving Supplier doc no. empty because the invoice has a purchase order. The check then has no number to test.
- Entering the supplier's number in Internal reference.
- Expecting the check to look at amount. It is by supplier and number only.

## Common questions

### Does Sage X3 check duplicate numbers on invoices with no order?

The same number check is documented on Purchase invoices. On Supplier BP invoices the Source document field records the supplier's invoice reference. Fill it in every time.

### Why do manufacturers get duplicate bills?

The same bill arrives through several routes and several people enter it. Month-end rush makes it worse. Agree one inbox and one person per supplier, then check supplier, amount and date.

### Is the supplier invoice number checked on Supplier BP invoices?

The same number check is described on Purchase invoices (field BPRVCR). The help for Supplier BP invoices says only that the Source document field records the invoice reference, so enter it every time.
