Sequential numbering lets you assign consistent, sequential document numbers to income invoices and credit notes. Available in Open Beta for companies not connected to external accounting software.
What Gets Sequential Numbers
Income invoices
Income credit notes
Payment requests (UK customers only)
VAT receipts (UK customers only, when owners use payment requests)
Note: Sequential numbering only applies to income documents. Expense invoices and credit notes continue using your accounting system's or supplier's numbering.
Who Can Use This Feature
Available to companies not connected to external accounting software (Xero, QuickBooks Online, etc.) and not using API integrations for document creation. Only users with permission to edit company details can configure settings.
How to Enable Sequential Numbering
Navigate to Settings > Manage Companies > [Select Company]. Under Sequential Numbering, toggle Use sequential numbering for invoices and credit notes to Yes.
Configuring Your Number Sequence
Invoice Prefix and Next Number — e.g. prefix "INV-" with starting number "1" generates INV-1, INV-2, INV-3.
Credit Note Prefix and Next Number — e.g. prefix "CN-" with starting number "1" generates CN-1, CN-2, CN-3.
Number Padding — add leading zeros: No Padding (1, 2, 3), 2 digits (01, 02, 03), 3 digits (001, 002, 003), 4 digits (0001, 0002, 0003), or 5 digits (00001, 00002, 00003).
Share invoice and credit note numbering sequence — toggle to Yes to use one shared sequence for both document types (with separate prefixes still applied).
Prefix requirements: mandatory when setting a starting number, must be unique within the company, maximum 5 characters, special characters allowed. Starting numbers can be up to 8 digits. An Example column shows a preview of each setting.
UK Customers: Payment Requests and VAT Receipts
UK customers see additional fields to configure sequential numbering for payment requests and VAT receipts. Configure a unique prefix and starting number for each. VAT receipt numbers are generated automatically when payment is made against a payment request.
Important Considerations
Settings lock after first use — once you save and create your first document, the prefix and starting number for that document type are permanently locked. Plan your numbering structure before creating your first documents.
Sequential numbers appear throughout Re-Leased — including invoice lists, owner statements, financial reports, bank reconciliation, email correspondence, PDF exports, workflow approvals, and budget reports.
Existing documents — documents created before enabling sequential numbering continue showing their original system IDs. Only new documents receive sequential numbers.
Audit trail — the system records who configured sequential numbering settings and when.
Troubleshooting
Sequential Numbering option not visible — check your accounting connections under Settings > Company > Accounting. This feature is only available for companies not connected to external accounting software.
Can't change prefix or starting number — settings lock after the first document is created. Contact Re-Leased Support if you need to change your numbering structure.
Gaps in sequence — gaps can occur if documents are deleted. Sequential numbering ensures each number is used only once for audit compliance.
Numbers not showing in reports — ensure settings are saved and that new documents have been created after enabling the feature.
