Built by ActiveEngine
Field Invoice is a product of ActiveEngine, a technology studio that designs and builds focused software tools for small businesses and tradespeople. We build things that solve one problem exceptionally well — no bloat, no unnecessary complexity.
Why we built this
Most invoicing tools are built for accountants, not for someone finishing a job at 5pm and needing to bill a client before driving home. Field Invoice exists for that moment — fast, professional, and out of the way.
