API Integration

API integrations that keep your systems in sync.

We connect your CRM, ERP and other tools so data moves on its own instead of being typed twice, and recovers cleanly when something fails.

Follow one payment

One payment, through all your systems.

Step 1 of 4

It happens

A customer pays, and your payment provider sends the event.

  • It happens
  • It is checked
  • Systems update
  • Failures recover

Signs you need it

When copy and paste starts costing money.

  1. 01

    The same data is typed twice

    Sales, finance and operations each keep their own copy.

  2. 02

    Numbers do not match between systems

    Someone reconciles them by hand each month.

  3. 03

    An integration breaks quietly

    You find out when a customer complains.

  4. 04

    A partner wants API access

    And you have nothing safe to give them.

  5. 05

    No-code automations keep failing

    They have grown beyond what they were meant for.

What we build

Integrations, built to recover.

Anyone can connect two systems. The work is in what happens when one of them fails.

API Integration

System integrations

Connect the tools you already pay for, so data flows between them.

  • Two-way sync
  • Field mapping
  • No double entry

Which fits?

No-code tool or a custom integration?

How we work

From systems map to a safe launch.

Six steps, the same on every project. AI-assisted workflows speed up the build, an engineer reviews every change, and at each step there’s something you can check for yourself.

Security built in from the first sprint, not added at the end.

“Good software takes work off your plate. We build what you need, show you as we go, and tell you straight when something isn’t worth building.”
Ali Raza, Co Founder

  1. Step 01

    Discovery and scope

    We start with what you are really building, not just a list of features. Goals, users, limits and edge cases are agreed before anyone writes code.

    Scope agreed before we build

    A written scope and milestone plan for you to approve.

  2. Step 02

    Architecture and planning

    We map the system before the build: how the parts connect, where the data goes and which APIs it needs. Fewer surprises, and no big rewrites halfway through.

    A plan you can read

    The architecture and milestones, in plain words.

  3. Step 03

    Build in short sprints

    We work in short cycles with something usable at the end of each one. You see progress the whole way, so problems get fixed while they are small.

    Working software, not status reports

    Real features you can try at each milestone.

  4. Step 04

    Testing

    Every release is tested the way people will really use it. Integration bugs and slow spots show up before your users find them.

    Releases you can trust

    Test plans and automated checks on every release.

  5. Step 05

    Release

    Only stable builds go live. We release step by step, so a problem is caught early and can be rolled back quickly.

    You own what we build

    The code, cloud and app store accounts are yours.

  6. Step 06

    Handover or keep building

    Once it is live, you choose: a full handover with documentation, or we keep building with the same team and the same rhythm.

    We stay after launch

    Support and new features, or a documented handover.

Before you commit

Know what to build, what to buy and what to skip.

Show us your tools and we will map the simplest way to connect them.

Talk to the people who build it.

We map your systems, find where data gets typed twice, and tell you what to connect first and what to leave alone.

  1. 1

    Tell us about it

    A few lines on the form is enough.

  2. 2

    Talk it through

    What you are building, where it stands and what you need next.

  3. 3

    A clear next step

    Scoping, a trial sprint, or an honest “you don’t need us”.

Can you connect a system with no API? Often, yes, through file exports, database access or other routes. We check what is possible first.
