Two lines that feed each other. We develop software end to end for clients, and we build products we own and operate.
The products are the proof of the services.
Most development shops answer “can you actually build?” with case studies from clients who cannot be named. We would rather answer it with a system you can open: a multi-tenant billing platform carrying a double-entry ledger, built to our own standards and operated by us.
One pays for the other’s independence. Both are held to the same standard.
End-to-end software development and outsourcing. Architecture, implementation, and the unglamorous parts — migrations, observability, the failure modes — carried through to production rather than handed over at the demo. Delivered as a project, or as engineers embedded in your team.
Software we own and operate, not client work with our name on it. subinc — multi-tenant billing infrastructure — is the first, and it runs on the same standards we bring to an engagement.
Multi-tenant subscription billing, metering and revenue on one double-entry ledger, with the payment processor behind an adapter rather than wired through the product.
subinc is in private beta. We run it; it is not yet generally available.

The totals beside each column are summed from the postings above them, and the difference is subtracted, not typed. Nothing here is a screenshot of a good day.
The entries arrive whole, both sides at once — animating one column ahead of the other would put the books out of balance on every intermediate frame, which is the exact drift the claim denies.
Both results are computed live. The left column runs the real arithmetic and prints whatever it gets.
Not 0.3. Every addition carries the error forward, and an audit finds it months later.
Integers all the way through. Formatting happens once, at the edge.
Same 1999 minor units. A fixed divisor is a 100× error on yen and a 10× error on dinar — the kind that only surfaces once real money has moved.
Change it. The adapter swaps; the posting does not move, because there is only one of it.

Rendered from one constant, shared by every processor above.
A polished interface over a ledger that drifts is worse than nothing — it hides the problem until an audit finds it.
We show the mechanism doing its job. A figure on a page is one we can point at in the source that produced it.
Retries, replays, partial outages and currency edges are where the engineering lives, and where the cost of being wrong is real.
We avoid dependencies that are hard to leave, and prove a seam is real by replacing what sits behind it.
A short description of the problem is enough to start. We will tell you plainly whether it is something we should take on.
