How to Edit Voucher Sequence and Reference Numbers (Customer and Supplier Vouchers)

The system allows you to control the voucher reference number sequence (customer vouchers and supplier vouchers), while ensuring:

• No number repetition

• No impact on previous vouchers

• Change applies only to new vouchers

Important Note:
By default, vouchers share a single unified sequence under the PYT prefix, which is what this article explains.
You can now separate the reference number by voucher type by switching on the option to separate the voucher reference number by type, under Settings → General Settings → Voucher Settings: payment vouchers get their own prefix and their own sequence, and receipt vouchers get their own prefix and their own sequence too. For the steps, see how to separate receipt and payment voucher reference numbers in Qoyod.
Unless you switch that option on, the unified sequence keeps working as described below.

First: Who has permission to modify the voucher sequence?

Voucher numbering settings can be modified by:

• Any user with permission to view general settings

Second: Path to access voucher numbering settings

Settings → General Settings → “Voucher Settings” from the top options

Third: Explanation of voucher reference number components

The voucher reference number consists of two parts:

• Identifier Number:
  A code indicating the document type
  Example: PYT

• Sequence Number Start:
  The number from which voucher numbering begins
  Example: 1

Practical Example:

If you enter:

• Identifier Number: PYT

• Sequence Number Start: 1

The numbering will be as follows:

• PYT 1

• PYT 2

• PYT 3
  And so on, automatically.

Fourth: Enable or disable the ability to edit the reference number

Within voucher settings you can:

• Make voucher numbering editable

• Or make it non-editable

What does this mean?

• When enabling the “non-editable” option:

  • Vouchers are numbered automatically

  • The number cannot be edited manually

• When enabling the “editable” option:

  • The user can, when creating a voucher

  • Edit the reference number manually

⚠️ Note:
Even with manual editing, the system does not allow duplicate voucher numbers.

Fifth: Saving changes

• Any modification to:

  • Identifier Number

  • Sequence Number

  • Editability

• Will not be applied until you click the Save button

And it will be applied immediately to new vouchers only.

Sixth: Impact of modification on vouchers

• Modification:

  • Does not affect old vouchers

  • Applies only to new vouchers

• Cannot create two vouchers with the same reference number

• This setting does not affect:

  • Invoices

  • Or any other documents

Seventh: Viewing all vouchers

To review all customer and supplier vouchers on one page:

• Go to Sales

• Then Customer Vouchers

• Then select All Vouchers from the top options
