Voucher Numbering, Invoice Series, Prefixes and Duplicate Control in TallyPrime

Voucher numbering is both an operational and audit control. A well-designed numbering method should be easy for users to follow, unique where required and stable across periods or branches.

Common approaches

• Automatic numbering for controlled sequencing
• Manual numbering where external document numbers must be preserved
• Prefix or suffix series for branch, period or document type

Duplicate risk

Manual numbering and imported data deserve special attention because duplicate or conflicting numbers can make reconciliation and document tracing difficult.

Before changing a live series

Review current numbering, existing documents and statutory requirements before altering a voucher type used in production.
