How to set up a voucher series for automatic numbering in Smart Books

Create a voucher series so your vouchers get numbers like INV/0001 automatically, and check the format before you save.

Level: beginner · Updated 31 Oct 2026

Before you start

A voucher series decides how your vouchers are numbered in Aicountly Smart Books. For example, you can make all sales vouchers read INV-0001, INV-0002 and so on. This article shows you how to set one up and check how the numbers will look before you save.

Before you start

  • You are signed in to Smart Books and have opened your company.
  • You know which type of voucher the series is for, such as Sales or Payment.

Create a voucher series

  1. Open Masters and, under Company, select Voucher Series. You see the list of series you already have.
  2. Select Add Series. The Voucher Series form opens.
  3. In General Info, type a Series Name. This is required. Pick a name you will recognise later, such as "Sales 2026".
  4. Choose the Voucher Type the series belongs to. This is also required.
  5. If you want, choose a Default Bank. This is a bank account that goes with the series.
  6. Under Voucher Numbering, choose Automatic or Manual. With Automatic, Smart Books gives each voucher the next number. With Manual, you type the number yourself.
  7. If you chose Automatic, set Renumbering Frequency to None, Yearly, Half Yearly, Quarterly or Daily. This decides how often the count starts again from the starting number.
  8. Enter the Starting No., the number your first voucher should get. It must be 1 or more.
  9. In Series Format, fill in the parts you need: Prefix, Prefix separator, Min fixed length of numeric part, Padding character, Suffix and Suffix separator. The separator can be a dash, a slash, a space or none.
  10. Look at the Series Format box on the right. It shows an example of your first number, so you can fix anything that looks wrong.
  11. Select Save. You see "Series created" and go back to the list.

A worked example

Say you want sales vouchers to read INV/0001. Set the prefix to INV, the prefix separator to a slash, the minimum length to 4 and the padding character to 0. With a starting number of 1, the preview shows INV/0001. Adding a suffix such as 26 with a dash as the suffix separator makes it INV/0001-26.

Change or delete a series

On the list, select a series to open it. Change what you need and select Save; you see "Series updated". When you edit a series, a Status section appears with an Active setting. Choose No if you no longer want to use the series. To remove it completely, select Delete and confirm.

Find a series quickly

On the Voucher Series list you can filter by Voucher type and by Numbering (Auto or Manual). Select Clear filters to see everything again.

If something goes wrong

  • If you see "Series name is required", type a name in Series Name.
  • If you see "Voucher type is required", choose a Voucher Type.
  • If you do not see the Prefix and Suffix fields, ensure you have chosen Automatic under Voucher Numbering.
