System integrations
System integrations that make your tools talk
We connect the systems you already run so data flows from one to the other on its own. No more exports, no more retyping, and no flimsy middleware layer that breaks every other week.
- Real native integrations, not flimsy middleware
- Fixed price agreed up front
- You own 100% of the code
In short
A system integration lets your tools exchange data with each other, so you never export, copy or retype anything again. We connect your existing systems through APIs, webhooks and, where it matters, genuine native integrations: for an e-commerce scale-up we connected 6+ data sources (Shopify, Amazon, bol.com, Google Analytics, Meta Ads) and normalised everything into one live source of truth. For Simply we built a native Salesforce integration in Apex with oAuth and certificates, not a hemmed-in iframe. The full source code is and stays yours and the price is agreed before we start.
What gets in the way
Most companies run on ten tools that don't know each other exist. The webshop has no idea what the warehouse knows, the CRM has no idea what the bookkeeping knows, and the gap gets bridged with exports, copy-paste and a spreadsheet someone updates in the evening. That doesn't just burn hours, it breeds errors: two systems that say slightly different things, and nobody sure which number is real. A system integration fixes that by letting the tools talk to each other directly. Data flows from source to destination on its own, at the right moment and in the right shape, so nothing gets entered twice. We're honest about how we build it. Sometimes a light webhook connection does the job. But when it really has to be right, we build a genuine native integration: for Simply, a Salesforce app in Apex with oAuth and certificates, rather than a flimsy middleware layer that falls over on every update. For an e-commerce scale-up, we pulled 6+ scattered data sources together into one live source of truth. Either way the outcome is the same: one place where the numbers add up, and no manual work in between. We think along with you: we listen first to what you want to achieve now and where you are heading, then choose the technology to match, for the most scalable and powerful result that is cost-efficient at the same time.
You export and paste data between systems
The same dance every week: export from one system, import into the next, or just retype it. It eats hours, and an error slips in at every step. An integration does this automatically, in the background, without anyone having to touch it.
Your tools never agree with each other
The webshop says X, the CRM says Y, finance says something else again. Every source has its own IDs, currencies and definitions, so nothing lines up. Without normalisation you keep guessing which number is the truth. We map everything to one shared model.
The same data gets entered twice
Creating a customer in the CRM and in billing. Retyping an order from the marketplace into the warehouse. Work that should happen once, properly, not twice, half-right. An integration makes sure a single entry lands everywhere it needs to.
An off-the-shelf connection keeps falling over
Standard Zapier or plug-in connections work until an API changes, a rate limit is hit or an edge case shows up. Then your process stalls and nobody knows why. We build connections with retry logic and monitoring, so you notice when something hiccups before it hurts.
What we build
How we help
API and webhook connections between your tools
We link your systems through REST and GraphQL APIs and webhooks, so an event in one system instantly triggers an action in another. A new order, a status change, a payment: it flows through to where it belongs in real time, instead of in an overnight batch.
Native integrations when it really has to be right
Sometimes a light connection isn't enough. Then we build a genuine native integration, with permissions, oAuth, certificates and external credentials. It runs inside your existing software as a full part of the system, not a hemmed-in iframe you have to copy data out of.
Multiple sources brought together into one truth
We connect your data sources, from webshop and marketplaces to analytics and ad platforms, normalise orders, fees, stock and customer data into one shared model, and feed it into a central KPI engine. Scattered figures become one live source of truth.
Normalisation, validation and data quality
The hard part of integrating isn't the connection, it's the data that runs through it. We deduplicate, validate, absorb API outages with retry logic and watch the health of every source. That's how you tell a real change apart from a technical gap, instead of guessing.
Monitoring so you notice when something hiccups
A connection that quietly fails is worse than no connection. We build in source-health monitoring and alerts, so you get a heads-up when a feed slows down or an API hits a limit, before the wrong numbers end up in a report somewhere.

Our approach
From idea to working software in four phases
Every project runs through the same four phases, so you always know what's happening, what comes next and what it costs — from first call to live software, usually in weeks rather than months.
- 01 Phase 1 Free intake
Understand & analyse
Everything starts with a good conversation. We map your goals, processes and the bottlenecks worth solving — no sales pitch, just an honest read on where the biggest win sits.
- 02 Phase 2 Free blueprint
Blueprint & quote
We turn the analysis into a blueprint: a clear plan showing exactly which steps we'll take and why, paired with one fixed quote. You know up front precisely what we build, what it costs and when it's done — no open ends, no hourly billing, no surprises afterwards. And getting that blueprint is completely free, no obligation.
- 03 Phase 3 Prototype in days
Build, test & deploy
Then we build, in short iterations. You see a working prototype in days and a finished product in weeks. We work on a modern, AI-native and secure stack — with data protection and GDPR in mind from day one.
- 04 Phase 4 100% your code
Implement & optimise
We launch, hand over the full codebase and keep improving on your terms. You get 100% ownership of the code we write — no lock-in, no licensing games. Hosting and maintenance are optional, never required.
What you always get
Fixed price
Agreed up front, never an open end.

Frequently asked questions
What does it cost to have a system integration built?
It depends on how many systems are involved and how clean their APIs are, but you always get a fixed price agreed up front. No open-ended hourly billing. We first look at which systems you want connected and what exactly needs to flow, and then we name a price for what you actually need. Want a ballpark for your situation? Book a call and we'll work it out concretely.
Can you connect to system X that we use?
Almost always. If the system has an API or webhooks, we connect through REST or GraphQL. If it doesn't, we find another route: an export-import bridge, a database connection or a middleware layer. For Simply we even built a native app inside Salesforce itself. Which approach fits best is something we decide once we look at your systems.
What's the difference between your integration and Zapier or a plug-in?
Off-the-shelf tools like Zapier are fine for simple, predictable flows. They just break the moment an API changes, a limit is hit or an edge case shows up, and then your process stalls with no clear reason why. We build connections with normalisation, validation, retry logic and monitoring underneath, so the data adds up and you notice when something hiccups. For Simply it went as far as building a genuine native Salesforce integration in Apex instead of a flimsy middleware layer.
How do you keep data reliable across multiple sources?
That's exactly the hard part, and where most of the work goes. At the e-commerce scale-up we connected 6+ sources that never agreed with each other: different IDs, currencies and definitions of revenue. We normalise everything to one shared model, deduplicate, validate and absorb API outages with retry logic. With source-health monitoring we separate a real change from a technical gap, instead of guessing.
What if a source or API goes down temporarily?
We build for that. Connections get retry logic, so a temporary outage doesn't lose data, and historical recalculation, so figures that arrive late (like marketplace settlements or refunds) still land in the right place. Source-health monitoring flags it when a feed slows or stalls, before the wrong numbers end up in a report.
Who owns the integration code?
You do. The full source code is and stays yours, with documentation and a clean handover. No vendor lock-in: you can continue with your own team or another party at any moment. We keep nothing behind a lock, not even the logic of your integrations.
