Login, roles and panels
Authentication, permission levels, admin interfaces and the business rules underneath them.
Applications That Hold Real Work
Service 02
Logins, permissions, business rules, panels and integrations with systems that were never designed to be integrated with. This is where the harder half of our portfolio lives.
Multi-tenant is where most shops stop
Building something that works for one customer is ordinary. Building it so a second customer can use the same installation without ever seeing the first one's data is where the architecture starts to matter. We built ZapFlow that way — isolated data, numbers and rules per company, one codebase — and it is in the portfolio for exactly that reason.
Integrating what resists integration
Our invoicing platform talks to Brazilian municipal tax endpoints: a different schema in every city, inconsistent documentation, and services that go down without warning. The code that matters is not the happy path — it is what happens when a government server returns malformed XML at 4pm on a deadline.
What's included
Everything in this service
Multi-tenant when you need it
One installation serving many customers with isolated data — designed in from the start, not bolted on.
Third-party APIs
REST, SOAP, webhooks and the ones with no documentation at all. Including retries and graceful failure.
Scheduled and event-driven jobs
Recurring routines, queue workers and processes that run without anyone watching them.
Schema and reporting
Database design that still performs when the table is large, plus the reports people actually open.
Generation and processing
Invoices, contracts, exports and imports — the paperwork layer most projects discover late.
How it runs
From brief to handover
Step 01
Discovery in writing
We send a questionnaire about the process, the users and the rules. You answer in writing.
Step 02
Technical proposal
Approach, data model sketch, phases, price and timeline. Recorded video walkthrough included.
Step 03
Build in phases
Usable milestones rather than one big reveal at the end. You see it working as it grows.
Step 04
Handover
Code in your repository, plus a recorded walkthrough of how the system is put together.
Questions
Before you brief us
One to two months for something with login, a panel and real business rules. We scope each one specifically — any firm number before seeing the rules would be a guess.
PHP and MySQL, which is what our production experience is in. If your project genuinely needs a different stack, we will say so rather than learn it on your budget.
Often, yes — after a paid audit. We will not quote a price for changing code we have not read.
We can, on our own VPS, or deploy to yours. If it is ours, that sits in the monthly maintenance plan.
