Invoice Number Sequence — PHP Composer Package (gap-free, year reset, PDO store, audit report)

Gap-free document numbering for PHP 8.1+: invoice, credit-note and order numbers with year/quarter/month/day reset, atomic counter stores (in-memory, JSON file, PDO with row locking), takeover of an existing number range, and a gap-and-duplicate audit report. No runtime dependencies.

Install

composer require numberkit/document-sequence-pro
