We help accounting firms ship the AI tools they build, safely.
We bring software engineering to the AI tools accounting firms build for themselves, and we make a desktop app that takes document work off your plate.
The gap between a working prototype and a tool you can ship
You’ve built an Excel add-in, an agent, or a bookkeeping automation. It’s about 80% done and works well in your hands. What remains is the hardest part: making it reliable and secure enough to put in front of the whole firm or even clients, so you can vouch for what happens to their data when something goes wrong. That production engineering is the work we do.
Engineering judgment and accounting context
Production-grade engineering
The error handling, data handling, authentication, and reliability that separate a prototype from something you can put in front of the whole firm or even clients.
Accounting-native context
We understand W-2s, trial balances, and client confidentiality, so our reviews land in your world rather than a generic security checklist.
A clear verdict
Every engagement has a fixed scope and a fixed price, and ends with a plain answer on whether a tool is ready for clients.
Two ways we work with you
Services for the tools you build
We review, harden, and extend the AI tools your firm has already built, from a one-time readiness check to an ongoing engineering partnership.

More about AnnuitYour data stays yours
Documents deleted on a fixed schedule
We delete the documents you work on from our servers after 24 hours. Documents your clients send wait for you, and we delete them fourteen days after you save them or the request ends. We keep a record of which documents passed through, never the documents themselves, until you delete the client.
Never used for training
Nothing you share with us is ever used to train AI models, ours or anyone else’s.
Never sold or shared for marketing
We do not sell your data or share it with competitors or marketers. The only outside parties that touch it are the service providers that run Annuit for you, listed in our Privacy Policy.
