API integrations: measure success instead of guessing
Without a pre-defined metric, you can't tell afterwards whether an API integration was worthwhile. Which numbers work, which ones mislead, and when to collect them.
The success of API integrations can only be measured if the baseline value was recorded beforehand — two weeks of tracking is enough. Useful metrics are processing time per transaction, percentage of cases that go through without intervention, and external response time. Team satisfaction in the first two weeks is not a useful benchmark.
01 — Measurement
How you measure success
- Define the one number beforehand. Without a baseline value, nothing can be proven afterward. Two weeks of tracking is enough for a reliable reference point.
- Processing time per case. The most direct metric: How long does the affected process take today, how long afterward.
- Percentage of cases that complete without intervention. This ratio typically rises significantly in the first weeks when refinements are made — it's the best early indicator.
- External response time. How quickly does someone who inquires receive an initial binding answer.
- What you should not measure: Team satisfaction in the first two weeks. Every transition feels worse initially than it actually is.
02 — Calculation
How to calculate it
Four numbers are enough: How often does the process occur? How long does it take? What does an hour cost internally? And what does the solution cost — one-time plus operation over three years?
An example: A process that occurs twice a week and takes 40 minutes each time ties up around 69 hours per year. At an internal hourly rate of 45 euros, that's roughly 3,100 euros per year locked in there. If a solution reduces this effort by two-thirds, it often pays for itself — depending on the actual quote — within one to two years. We'll give you the exact figure for your case after the initial meeting.
This calculation is deliberately conservative: it only accounts for the time saved, not the errors avoided or the orders that come through due to faster response. In practice, the benefit is usually higher — but you shouldn't count on it before you've measured it.
03 — Context
What experience shows
The most expensive part of an integration is never the normal case, but what happens when a system doesn't respond.
04 — Questions
Frequently asked questions
Is an interface more secure than a manual export?
Significantly, because human errors during export and import are eliminated and every exchange is logged. A manual export leaves no trace if something was overlooked.
What happens during an outage?
The connection remembers what hasn't been transferred yet, tries again, and reports after multiple failed attempts. Data isn't lost, it arrives delayed.
Can multiple systems be connected simultaneously?
Yes, that's actually the more common case — for example, shop, inventory management, and accounting together. Each connection is planned and tested individually, even if everything works together in the end.
What does maintenance cost during operation?
As long as none of the connected systems changes fundamentally, ongoing effort is low — monitoring reports itself when something doesn't fit.
Who maintains it later?
You receive code and documentation. We deliberately build with widely used technologies so that switching is possible.
What if our legacy system has no interface?
Then there are usually workarounds: database access, automated file exchange, in exceptional cases surface automation. All are more fragile than a real interface. We'll honestly tell you how stable such a solution will be before you decide.
How often is data synchronized?
From immediately to nightly — depending on what's technically necessary. Immediate synchronization isn't always better: for systems with post-processing, a nightly run is often the more stable choice.

Let's talk briefly about whether this makes sense for you.
A twenty-minute conversation is usually enough to clarify whether a project makes sense. If not, we'll say so — that's cheaper for both sides than an offer nobody needs.
