Tables & field types — Auto-number fields: invoice and order numbers that mind themselves

An Auto number field gives every record a permanent sequential number — perfect for invoices, orders, tickets, and quotes. Choose a starting number when you create the field (say 1000); existing records are numbered immediately, oldest first, and every new record takes the next number automatically no matter how it arrives: typed into the grid, imported, created by an automation, the API, a connector, or the AI. The numbers are read-only by design — nobody can edit, reuse, or accidentally clear one — and they sort and filter like any other number. Records imported with their own numbers keep them.
