Every document.
Numbered correctly.

Configurable numbering for every document type — invoice prefixes per fiscal year, PO sequences per branch, GRN numbers per warehouse, SO numbers per business unit. Statutory-compliant, gap-free, audit-ready.

Configurable Patterns

Prefix. Sequence. Format.

Define numbering patterns per document type and per organizational scope. Invoice prefix INV/2026/, PO sequence per branch, GRN per warehouse. Common patterns templated; custom patterns supported.

  • Patterns per doc type: invoice, PO, GRN, SO, etc.
  • Scope: per company / branch / warehouse / business unit
  • Prefix + sequence + fiscal year placeholders
  • Zero-padded numbers (INV-00001 vs INV-1)
  • Year-end auto-reset (next FY starts at 1)
  • Multi-format support: INV/2026-27/00042 etc.
Statutory Compliance
Statutory Compliance

Statutory Compliance

GST-compliant. Gap-free.

GST law mandates unique, sequential, gap-free invoice numbers per GSTIN per fiscal year. Engine enforces this absolutely — no skipped numbers, no duplicates, no rollover gaps. Auditor-ready.

  • Gap-free sequential numbering enforced
  • Per-GSTIN uniqueness per fiscal year
  • Cancellation preserves number (no reuse)
  • Audit log of every number allocation
  • Reservation + commit for transactional safety
  • GSTR-1 ready output
Lifecycle Management

Lifecycle Management

Open. Lock. Roll over.

Manage active and historical series. Lock old series at year-end. Roll over to new year automatically. Override sequence if migrating from a legacy ERP with existing numbers.

  • Open / active series per scope
  • Lock at fiscal year-end
  • Auto-rollover to next FY
  • Override start sequence for migration
  • Number gap report + reconciliation
  • Bulk regeneration in dry-run mode

Per-Doc Series

Separate number series per document type — invoices, POs, GRNs, SOs, DCs, credit notes, debit notes. Each with its own pattern and sequence.

Drill in

Multi-scope

Scope numbering per company, branch, warehouse, business unit, or any combination. Group structure with 5 entities? Each can have its own invoice prefix.

Drill in

Fiscal Year Reset

Series automatically resets at fiscal year boundary. Last invoice of FY 25-26 was INV/25-26/8429; first of FY 26-27 is INV/26-27/00001.

Drill in

Gap-free Enforcement

GST law mandates gap-free sequential numbering. Engine reserves numbers atomically; rollback on transaction failure releases the reservation cleanly.

Drill in

Cancellation Handling

Cancelled invoices retain their numbers (per GST law). Cancellation is marked; number is never reused. GSTR-1 reflects cancellation correctly.

Drill in

Pattern Templates

Pre-built patterns for common Indian formats: INV/YY-YY/NNNN, PO/CO/YYYY/NN, GRN/WH/MM/YYYY/NNN. Customize without code.

Drill in

Allocation Audit

Every number allocation logged with timestamp, user, source transaction. GST auditor can trace any invoice number to its origin.

Drill in

Migration Support

Importing from legacy ERP? Set the starting sequence to match. New numbers start where the old ones left off — no overlap, no gap, no confusion.

Drill in

Gap Report

Reports show any gaps or anomalies. If a number is missing, the report shows why (cancellation, system event) — and provides the audit log.

Integrations

Works with everything else.

Every Number Series action flows into the other modules — no manual data re-entry, no reconciliation pain.
