Documents over data
An invoice is a document a human will read and decide whether to pay. We design every PDF like it could be framed.
№ 002/About
We make a quiet,
careful invoicing tool.
Built by Asad Mahmood. Multi-currency, seven templates including POS and clinic receipts, the calculations done right.
The story
Inbill started as a side project to fix one specific frustration: every invoicing tool I tried was either built for accountants who already speak debit-credit, or for venture-funded SaaS that wanted to be a "platform". Nothing in the middle for a person doing quiet, good work.
So this is the middle. A tool small enough that one person can hold the whole thing in their head, careful enough that the numbers always add up, and honest enough that you can read the source if you want to.
"Software you can hold in your head."
Three principles
we won't bend.
02
Numbers are the product
Tabular figures, real math, audit-grade totals. The number on screen is the number that prints, every time.
03
No upsell anxiety
Free until you outgrow it. One paid plan, one price. No per-client fees, no template lock-ins, no "talk to sales".
