Web apps
API development and integration
We build APIs and integrations that connect your website, apps, CRM, payments and back-office systems, so data moves on its own and stays correct everywhere. No more copying orders, leads or stock numbers by hand.

- Best for
- Businesses whose systems do not talk to each other, and products that need an API for apps or partners.
- Price
- Fixed quote after one call
- Progress
- A preview link every week
- Node.js
- NestJS
- PostgreSQL
- Stripe
- Postman
Sound familiar?
You are in the right place if
- Leads from the website are typed into the CRM by hand.
- Your app needs a back end, and the website and app keep getting out of step.
- A partner wants to connect to your system and you have no API to offer.
- An integration breaks quietly and nobody notices until a customer complains.
What you get
Everything included
Delivered together and tested before launch.
- 01
Integration map
Which systems hold which data, what should sync and in which direction.
- 02
Secure APIs
REST or GraphQL APIs with authentication, rate limits and clear documentation.
- 03
Connections to your tools
CRMs, payment gateways, couriers, accounting, email and messaging platforms.
- 04
Webhooks and queues
Events handled reliably, with retries so a short outage does not lose data.
- 05
Monitoring
Alerts when an integration fails, and logs that show what happened.
How it works
4 steps, one fixed price
A single integration can take days to a few weeks. A full API for an app is planned with the app itself.
- 1
Map
We map the data, the systems and the rules for each sync.
- 2
Design the API
Endpoints and data formats agreed and documented before code.
- 3
Build and test
Built against test accounts, with automated tests on every sync.
- 4
Launch and monitor
Switched on in stages, watched closely in the first weeks.
Pricing
A fixed quote, so you know the full cost up front
Each integration or API gets a fixed quote once the data map is agreed.

- 01Number of systems and data types
- 02Quality of the other systems' APIs
- 03Volume of data and how real time it must be
- 04Security and audit requirements
Is it right for you
An honest answer before you spend anything
A good fit
- Businesses whose systems do not talk to each other, and products that need an API for apps or partners.
Probably not the right fit
- If the two systems already offer a ready-made connector, use it. We will tell you if one exists.
- If a no-code tool like Zapier or Make can do it reliably, that may be cheaper. See our workflow automation service.
REST or GraphQL?
REST is simpler and widely supported, and fits most integrations. GraphQL suits apps that need flexible data from many sources. We recommend per project.
Can you work with our old system?
Usually. If it has an API, we use it. If not, we look at database access, file exports or other safe options.
How do you keep data secure?
Encrypted connections, access keys with the least permissions needed, and logs of every request.
Will you document the API?
Yes. You get clear documentation your team or partners can use.
Want your systems to talk to each other?
Tell us what you need. After a 30-minute call, you get a fixed quote for the whole project.
