How to Record Past Supplier Bills

Overview:

Recording past supplier bills allows businesses to establish outstanding Accounts Payable (AP) balances from transactions that were created before the cut-off date or go-live date. This process is commonly performed during system migration, opening balance setup, or when transferring records from a legacy accounting system.

Past supplier bills are typically recorded to reflect unpaid historical purchase transactions so that supplier balances, aging reports, and payment records remain accurate in the new system.

Depending on business requirements, past transactions may be recorded either as:

• Consolidated balances per supplier, or

• Itemized historical documents based on original bill references

When recording historical transactions, ensure that:

• The transaction date is earlier than the cut-off date or accounting start date

• Outstanding balances are verified against prior accounting records

• Related historical payments, credit notes, or debit notes are also considered to maintain accurate supplier balances

The Accounts Payable opening balance is derived from the net effect of:

• Past Supplier Bills

• Past Supplier Debit Notes

• Past Pay Bills

• Past Supplier Credit Notes

Only outstanding balances as of the cut-off date should be recorded.

Scenario:

Your company is migrating from a legacy accounting system to N3 AI Accounting for the January to December 2026 financial year. As part of the migration, the company needs to record all unpaid supplier bills dated before January 1, 2026, so that supplier balances and Accounts Payable reports remain accurate in the new system.

Some suppliers have a single outstanding balance, while others require individual historical bills to be recorded for tracking and reconciliation purposes.

Prerequisites:

• Supplier master records must already exist in the system.

• The financial year and opening balance period must already be configured.

• Outstanding supplier balances must be verified against the previous accounting records before migration.

Procedure:

1. Prepare the list of outstanding supplier bills from the legacy records or prior accounting system.

2. Verify that the bill balances represent unpaid amounts as of the cut-off date.

3. Review whether the bills will be recorded as:

• Consolidated balances per supplier, or

• Individual historical bill transactions

4. Confirm that the transaction dates of the past bills are earlier than the financial period start date or cut-off date.

5. In the navigation pane, go to Account Payable > Bills.

6. Click Add to create a new past supplier bill entry for each required supplier record.

7. Enter the document date first (must be earlier than the financial period start date or cut-off date). The system automatically changes or classifies the document as a past bill.

8. Select the supplier and applicable historical bill details, such as:

• Document Number

• Ref No.

• Description

• Balance

• Tax Code

Note:

If Tax/VAT details are entered for historical reference purposes, the VAT portion does not generate a separate posting to the VAT General Ledger account because only the outstanding payable balance contributes to the Accounts Payable opening balance.

9. Review the entered amounts carefully and Save the transaction.

10. Repeat the process for all remaining outstanding supplier bills.

11. After all entries are completed, review the reflected opening Accounts Payable balance in General Ledger > Opening Balances to verify that the recorded balances match the historical records.

Application (General Use Cases):

• Establish opening Accounts Payable balances during system migration

• Transfer outstanding supplier balances from a legacy accounting system

• Maintain supplier aging continuity after go-live

• Support historical balance reconciliation

• Help maintain continuity and accuracy of Accounts Payable reporting

• Retain reference to historical supplier bill records for audit and tracking purposes
