Create and manage numbering series

A series gives one kind of document its numbers for one branch and one fiscal year. This article is the administrator's view: how to create a series, what each field does and what to check. The effect on invoices and receipts is in the Accounting knowledge base.

The Document numbering screen

Open Document numbering (menu Document Numbers). The list shows, for each series: Module code, Description, Start date, Prefix, Suffix, Body length, Fill up char, Start no, End no, Branch, Last document (the latest number given) and Status. Filter by Branch, Description, Module code, Prefix or Suffix.

Add a series

  1. Open the form
    Who
    Administrator
    Where
    Document numbering > Add
    What changes
    The form opens with the Start date, End date and Suffix filled from the active fiscal year (Fiscal years: create, activate and prepare the next one). Change them when you prepare next year's series.
  2. Choose the module
    Where
    Module
    What changes
    The kind of document the series numbers (sales invoice, receipt, return, journal and so on). Choosing it fills Prefix with its code and a dash.
  3. Name and period
    Where
    Name, Start date, End date
    Needs
    A name of up to 50 characters. Both dates inside the fiscal year the series is for, the start not after the end.
  4. Shape the number
    Where
    Prefix, Suffix, Body length, Fill up char ?, Fill up char
    What changes
    The number printed is prefix, the counter padded to the body length, and suffix. Doc total length shows the total and cannot be edited. Choosing the body length fills End no with the largest number that fits.
    Needs
    Prefix and suffix up to 6 characters each. Body length 1 to 7. The total of prefix, body and suffix at most 20.
  5. Set the counter
    Where
    Start no, End no, Current no
    What changes
    Current no is where the counter starts (use the start number for a new series).
    Needs
    Start below end; current not below start and below end.
  6. Choose the branch
    Where
    Branch
    What changes
    The branch the series serves. It is switched off when the company is not branch based.
  7. Switch on
    Where
    Active, Default
    What changes
    Only an active series is offered. Default matters for the journal voucher series: it marks the one the automatic depreciation journals use. Tick it on one journal series, no other kind needs it.
  8. Save
    What changes
    "Document saved successfully". The series is ready for the branch.

One series per kind, per branch, per year

Give every branch a series for every kind of document it uses, and give every new year its own: a different suffix or prefix, because two series cannot share a module, prefix, suffix, body length and fill character. A series that has run out or whose dates have ended stops the first document after it.

Change, switch off, delete

  • Edit changes the form. Do not use it to move the counter: Current no on an existing series does not change the number the next document gets (see below). To restart or skip numbers, add a new series.
  • Deactivate or Activate from the row, or select rows and use Activate all or Deactivate all.
  • Delete is offered only while the series is unused (its counter is still at its start number), and Delete all is offered for several. In this release the delete is refused with a general error even for an unused series: switch the series off instead.

Common questions

How do I restart numbering, or skip some numbers?

Add a new series that starts where you want. Changing Current no on a saved series does not change the next number.

A branch has no Add button on the sales screens.

It has no active series for that kind of document with dates inside the active fiscal year. Add one (A document number is missing, repeats or stops).

I made a series by mistake. Can I delete it?

In this release the delete is refused. Deactivate the series instead.

Can two branches use the same prefix?

Not with the same suffix and the same body length: the screen refuses a second series of the same shape, whatever its branch. Give each branch its own prefix, for example SB- for Head Office and SB2- for the second branch (Branches).

My clerks pick the wrong series from the Add list.

The list shows each series' Name in capital letters. Give every series a name that says what it is for, such as the branch and the year, and switch off the series nobody should use.

What do I enter for Start no and Current no in next year's series?

The start number you want the year to begin at, normally 1, and the same number for Current no. A new series counts from Current no.
