What we do differently
A system that invoices or keeps accounts cannot fail silently. These are the decisions we make by default.
Isolation that fails closed
Each company sees only its own data. If a query forgets to say which company it is asking about, it returns nothing. That is the difference between a visible error and a silent data leak.
Money is calculated on the server
Never in the browser. What the user sees is the result of a calculation done where nobody can modify it.
Charges that do not duplicate
Payment gateways resend notices when they are unsure. Our systems are built to receive the same notice twice without charging twice.
Encrypted credentials, logged access
Third-party keys are stored encrypted and every access is recorded. When something breaks, there is a trail to read.
Platforms we already operate
These are live products with paying customers. We can adapt them to your case or build you something new.
DarGratia — church accounting
Congregations record tithes and offerings, then owe a calculated remittance to their national council. The arithmetic is subtle and the money belongs to other people, so every required amount appears next to what was actually sent, with payment reference and dual signatures.
Medios Plano — drawing engine
A Python engine that reads an architectural plan into a structured model, resizes it without breaking construction geometry, and emits a dimensioned permit set with a material takeoff that reconciles with the drawings.
Frequently asked questions
Do you build from scratch or start from something?
Both. We have our own platforms — billing, CRM, church accounting — that we can adapt, and we also build from nothing when the problem does not resemble anything that exists.
How do you protect each client's data?
With tenant isolation at the data layer that fails closed: if a query does not say which company it belongs to, it returns nothing rather than everything. Credentials are stored encrypted and access is logged.
Do you accept card payments?
Yes. We integrate Stripe and other gateways. Amounts are calculated on the server, never in the browser, and payment webhooks are built so that receiving the same notice twice does not charge twice.
Does the system live on my server or yours?
Either. We can host it on our servers in Houston or deliver it on yours. In both cases the code and the data are yours.
Do you support it after delivery?
Yes. Most of our software clients stay with us years later, because a system in production needs someone who answers when something changes.
