API integration and automation so your programs talk to each other.
Your web shop, accounting software, bank, CRM and courier each work fine on their own - and someone spends hours every week copying data between them. We connect them through their APIs, automate the steps in between, and make sure nothing gets lost when one of them has a bad day.
- Keep the tools you have - we connect them instead of replacing them.
- Orders, invoices, payments and stock move on their own, without retyping.
- If one system is down, nothing is lost: the work waits and goes through later.
- Every connection is monitored, and a person hears about problems first.
Connect the tools you already have
Most companies do not need new software as much as they need their existing software to stop being islands. An order arrives in the web shop, someone types it into accounting, someone else books the courier, and at the end of the month someone matches the bank statement by hand. Every manual step costs time and adds typos.
We build the connections in between: small, typed services that read from one system and write to another through their APIs - including the old ones whose documentation is a PDF from 2014. Every connection has timeouts, retries and a safe place for work that cannot be finished yet, so a slow courier API or a maintenance window at the bank never loses an order.
Typical jobs: web shop to accounting and warehouse, e-invoicing, payment and bank reconciliation, CRM and newsletter sync, courier labels and tracking, and a public API so partners can integrate with you. When the real problem is that the data lives in spreadsheets, a custom ERP is the better fix - we will tell you which one it is.
How it works
From copy-paste to “it just happens”
Three moments from a small company’s week - before and after its programs were connected.
-
An order arrives and a person copies it into accounting, the courier’s site and the warehouse sheet. Hours every week - and a typo now and then.
-
The same order flows from the shop to accounting, the warehouse and the courier in seconds. The invoice and the shipping label make themselves.
-
The courier’s system is offline for an hour. Orders wait safely in line and go out the moment it is back - and someone gets a message, just in case.
In practice
Illustrative scenarios - the kind of work we take on, not client case studies.
Shop, warehouse and accounting that agree
- The problem
- An online shop sells from a warehouse whose stock lives in an older ERP. Stock moves by nightly CSV export, so popular items oversell during the day, and every invoice is retyped into the accounting software by hand.
- What we build
- A small integration service between the three. Orders from the shop go into a queue; a worker reserves stock through the ERP’s API and posts the invoice to accounting. Stock changes flow back every few minutes instead of every night, failed calls retry, and anything stuck raises an alert.

Bank statements matched automatically
- The problem
- Every month someone spends two days matching bank statements against open invoices, line by line.
- What we build
- Payments are pulled from the bank every day and matched to invoices by amount, reference and customer. Only the doubtful ones land on a person’s list, with the likely match suggested.

Retiring a fragile nightly script
- The problem
- A reporting pipeline is one script on one server, pulling data from three online tools. When a source renames a field or times out, the report is silently wrong and nobody notices until Monday.
- What we build
- A pipeline with checks on every source, safe re-runs that never duplicate rows, and a history of every run. A failure alerts the right person with the failing record attached; re-running a day is one command.

What you get
- A map of your systems and data flows: what to connect first, and why
- Connections built on each system’s official API - or carefully around it when there is none
- Retries, a waiting line for failed work, and no duplicates when something arrives twice
- A dashboard of every connection: what went through, what is waiting, what failed
- Alerts that reach a person before a customer notices
- A documented public API, if partners need to connect to you

Questions people ask
Your question is not on the list? Ask us directly - we reply within two working days.
Ask a questionHow much does an integration cost?
A single connection between two systems with good APIs is a small project; a web of five systems with old software in the middle is a bigger one. After a 30-minute intro call we send a written plan with a fixed price per connection. Systems without usable documentation get a short technical check before we quote the rest.
Our software is old - can you still connect it?
Usually, yes. If there is no API, there is often a database, a file export or an import folder we can work with safely. We check what is possible before promising anything.
What happens if one of the systems is down?
The work waits in a queue and is retried automatically; nothing is lost and nothing is sent twice. If a system stays down, a person on your side gets a message.
Do you work with e-invoicing systems?
Yes. We connect accounting and ERP software to e-invoicing platforms and to the formats your market requires, and test the whole flow end to end before it goes live. Requirements differ by country, so we check yours during planning.
Integration or a new system - how do we decide?
If each of your tools does its job well and the pain is the copying in between, connect them. If the tools themselves are the problem - or the data lives in spreadsheets - a custom system is the better investment. We will tell you which one we think it is, and why.
Tell us which programs need to talk.
List the tools you use and where data gets retyped. We reply within two working days with a link to a 30-minute intro call, then send a plan and a fixed-scope estimate.
