We connect the systems you use through APIs so data flows between them automatically — without manual re-entry and without the risk that one system shows something different from another.
Integration that lets you enter data once, not in three systems at once
API System Integration
We connect the systems you use through APIs so data flows between them automatically — without manual re-entry and without the risk that one system shows something different from another.
You have an online store, an accounting system, and a wholesale platform — and you copy every order by hand from one to the next. Stock levels in the store don't match stock levels at the wholesaler, because the update arrives late, or gets forgotten entirely in the rush of other tasks.
Systems that were supposed to make work easier end up creating extra work: patching over the fact that they don't talk to each other. Someone on the team spends part of the day copying data between screens instead of doing the work where they actually add value.
The worst outcome isn't a missing internal report — it's a customer who orders a product shown as available in the store, even though it's been out of stock at the wholesaler for a week, because nobody manually updated the count.
API integration connects the systems you use so data flows between them automatically — an order from the store reaches accounting and the warehouse without your involvement, and product stock updates everywhere at once.
Before integrating, we map out exactly what data needs to flow, and in which direction, between the systems — we don't connect everything to everything "just in case," since that raises the risk of errors and makes maintenance harder. We build integrations with error handling — when one of the systems is temporarily unavailable, data doesn't get lost, it waits to sync again.
What we don't do: we don't launch an integration without testing it on real data — sample test cases don't reveal the edge cases that only show up in day-to-day work.
What You Get
- Data entered onceVisible automatically across every connected system, without manual re-entry and the errors it produces.
- Consistent stock levelsAccurate in the store and at the wholesaler at the same moment, so a customer never orders something that's no longer there.
- Team time reclaimedHours previously spent on repetitive data entry go toward work that actually needs a person.
- Connection documentationWritten in a way the next developer can understand, in case the integration needs to be extended later without our involvement.
We've built integrations between online stores, accounting systems, and wholesale platforms with varying degrees of API maturity — on a call we'll show you examples of completed integrations and walk through how the data-flow mapping worked.
Scope and Pricing
Scope covers analysing the systems to be connected and mapping the data flow between them, building or configuring the API connection, handling errors and edge cases, testing on real data, and documenting the connection.
- Analysis of the systems and agreement on what data needs to be synced.
- Integration architecture design.
- Building or configuring the connection.
- Testing on real data and launch with monitoring of the first syncs.
Price depends on the number of systems integrated, the availability and quality of each one's API documentation, the complexity of the mapped data, and the sync frequency. You get a full quote after analysing the systems you want to connect. You pay after each stage is accepted, so you see a working connection before paying for the next step.
Our Guarantees
Testing on real data before launch. We also check what happens when one of the systems is temporarily unavailable, before the integration goes live in production.
Documentation the next developer can understand. The integration isn't a black box known only to us — you can hand it to any team.
Error handling as standard, not an add-on. When one of the systems is unavailable, data waits to sync again instead of getting lost.
Integration code in a repository on your account, wherever technically possible. You have visibility into the solution, not just into its behaviour.
Availability
Integration time depends mainly on the quality of the API available on the connected systems' side — linking two systems with well-documented APIs takes less time than integrating with an older system that has no official API. We set a realistic schedule after the analysis.
Order Your System Integration
Write to us with a list of the systems you want to connect, and a description of the data that should flow between them. We'll run the analysis and propose a scope and quote.
What You Lose by Waiting
Every additional week of manual data entry is another chance for an error to reach a customer as an outdated stock level, before anyone notices.
In Short
Integration designed from mapping the real data flow, not connecting everything to everything · error and edge-case handling built in · testing on real data before launch · documentation the next developer can understand · sync frequency matched to your actual needs.
Frequently Asked Questions
What happens if one of the systems goes down during a sync?
We build integrations to handle this — data waits to sync again once the system is back up, instead of getting lost. This is one of the things we test before launch.
Will you integrate systems that don't have an official API?
In many cases, yes, though it requires a different technical approach and usually more time — during the analysis stage we check what integration options exist for the specific systems.
How often will the systems sync?
We set the frequency, real-time or periodic sync, during the analysis stage, depending on how critical up-to-date data is in your case.
How many systems can be connected in a single integration?
There's no fixed limit — the number of connected systems affects complexity and price, which is why we establish during analysis which connections are actually needed.
What happens to the integration if we switch one of the systems in the future?
The connection documentation makes it easier to update the integration when a system changes — the scope of work depends on how different the new system's API is from the previous one.
