Every document Horizon213 issues carries a number that identifies it for good. It is what you quote on the phone, what your accountant files by, and what an inspector asks for.
Reading the number
FV-2026-00184 is three parts: what kind of document, which year, and which one
it is in that year.
The prefix tells you the type at a glance — FV a sales invoice, DV a
quotation, BL a delivery note, CS a counter sale, AST a fixed asset. You
will learn them faster than you expect, because you will be reading them aloud.
The year is the document's own year, not the current one. A January invoice still says the year it was issued in, forever.
The number arrives on confirmation, not before
A draft has no number. That is deliberate, and it is the same rule everywhere: an invoice gets its number when you confirm it, a receipt when you validate it, a delivery note when the goods actually go.
The reason is that a number is a promise. Once FV-2026-00184 exists, it is that
document and no other, and it will still be that document in five years. Handing
numbers to drafts that might be thrown away would break the promise on the first
change of mind.
So: take as long as you like over a draft. Nothing is committed until you confirm, and nothing is numbered either.
There are no gaps
Numbers run in sequence with nothing missing. This matters more in Algeria than it might elsewhere — a gap in an invoice sequence is the first thing anyone checking your books will ask about, because historically it meant a document had been removed.
Horizon213 cannot produce a gap, because it never removes anything. A cancelled document keeps its number and stays in the register saying Cancelled. A corrected one keeps its number too, with the correction beside it.
That is the same rule as corrections being reversals, seen from the outside: the sequence is intact because the history is.
What you cannot do
You cannot choose a number, skip one, or reuse one from a document that was cancelled. Every attempt to reserve a number "for later" ends in a gap somebody has to explain.
What you can do is record the other side's reference. A supplier's invoice carries their number as well as your own, and a quotation converted to an invoice keeps a link to the quotation it came from — so the paper trail works in both directions without anyone renumbering anything.
