How can I change the invoice serial numbers in Wafeq?

When would you need to adjust invoice numbering?

• When starting to use the system and want to begin with a specific number.

• If you deleted an invoice and want to maintain a logical sequence.

• When switching from another system and need to continue a certain sequence.

• If the system is generating unexpected invoice numbers and you’d like to control them.

Ways to update invoice numbering in Wafeq

1. Change the invoice number during creation

When creating a new invoice, Wafeq will suggest a number automatically.
You can manually edit this number before saving.

Example: If the suggested number is 105, you can change it to 2024-001.

2. If an invoice was deleted and sequence was broken

Wafeq does not reuse an invoice number even if it was deleted.

To maintain your sequence:

• Simply enter the desired number manually when creating the next invoice.

• Or skip the missing number (deleted invoices do not appear in reports).

3. Adjust the default numbering pattern for future invoices

To change the sequence format going forward:

1. Go to “Sales” from the main menu.

2. Click “Sales Invoices”, then click “Create”.

3. In the top field labeled “Invoice Number”, manually enter your custom number (e.g., INV-2024-001).

4. Complete the invoice and save.

Wafeq will automatically suggest the next number using this pattern.

4. Check the current numbering pattern

To see your current numbering:

1. Go to “Sales Invoices” and click “Create”.

2. The suggested number reflects your current pattern.

3. If it’s not what you want, override it with your preferred sequence.

Notes

• Invoice numbers must be unique within the same company.

• Always ensure the next number doesn’t conflict with an existing invoice.

• It’s not recommended to change numbering sequences after starting tax reporting.
