Invoice Numbering Configuration

LiteWork automatically numbers your invoices and quotes using a prefix and auto-incrementing sequence. You can customise the prefix, starting number, and padding to match your business’s numbering style.

How It Works

Each new document gets the next available number in the sequence. For example, with prefix “INV-” and 3-digit padding starting at 1:

INV-001, INV-002, INV-003, ...

Invoices and quotes have separate sequences, so invoice INV-001 and quote QT-001 can coexist without conflict.

Configuration Options

Go to LiteWork Settings → Document Settings to configure numbering:

Invoice Numbering

  • Prefix: The text before the number (e.g., “INV-“, “INV.”, “#”). Can be any string.
  • Starting Number: The number to begin from (e.g., 1, 100, 1000). Useful if you’re continuing from a previous system.
  • Padding: How many digits to display. With 3-digit padding, invoice 1 becomes “001”. With no padding, it’s just “1”.

Quote Numbering

Quotes have their own independent prefix, starting number, and padding. Common prefixes include “QT-“, “Q-“, or “EST-“.

Examples

Prefix Start Padding Result
INV- 1 3 digits INV-001, INV-002, INV-003
# 100 None #100, #101, #102
LW- 1000 4 digits LW-1000, LW-1001, LW-1002
QT- 1 2 digits QT-01, QT-02, QT-03

Manual Overrides

When creating a new document, the number is pre-filled from the sequence. You can change it manually before saving — but be mindful of duplicates. LiteWork will warn you if the number already exists.

📝 Note: Once saved, an invoice number cannot be changed. The number becomes part of the document’s identity and audit trail.

Switching from Another System

If you’re migrating from another invoicing tool and want to continue your existing number sequence, set the starting number to the next number after your last invoice. For example, if your last invoice was #247, set the starting number to 248.
