System integration

Let your business systems work together automatically

Website, CRM, calendar, email and accounting: most businesses already use these systems, but they often don't talk to each other. Connecting your business systems lets information flow automatically, without anyone having to enter the same data twice.

Recognizable signs of disconnected systems

  • The same customer data gets typed into multiple places by hand
  • Information in one system no longer matches another system
  • Someone regularly exports and imports files between tools
  • There's no accurate overview because data is spread across systems
  • New employees have to learn several disconnected systems

How we build an integration

We start with an inventory: which systems are the source of data, which systems need to receive it, and who owns which piece of data. That prevents two systems from disagreeing about what the "truth" is.

Then we define the trigger (what starts the sync: a new record, a change, a fixed schedule), the direction of the sync (one-way, or do changes need to flow back too), and how fields from one system are translated into the other (mapping and validation).

Reliability, explained in plain language

An integration that works once is not the same as one that keeps running reliably for months. So we build with a few fixed principles: accidentally triggering the same action twice should never create a duplicate record, errors are logged so you can trace them, and a failure triggers a retry instead of data silently disappearing.

We avoid unnecessary jargon in the documentation you receive: you don't need to know what an API is to understand what the integration does and what happens if something goes wrong.

API, webhook, or standard connector

Some systems offer a ready-made connector that makes integration fast and stable. Other systems have their own API that we connect to directly, or work with webhooks that push data automatically when something happens. Which route fits best depends on what the systems involved support, and we determine that per integration.

Handover and maintenance

On delivery you get documentation explaining what the integration does, what data flows through it, and what to do if something changes (for example a new field in your CRM). For ongoing maintenance, for instance when a connected system rolls out an update that affects the integration, a retainer is available.

Privacy, access and data minimization

  • Only the data functionally needed for the integration flows through, not entire datasets by default
  • The integration runs in your own accounts and systems, not with Manuless
  • Every integration is designed in line with GDPR
  • Credentials and API keys are never hardcoded
  • Access to each system is limited to what the integration actually needs
We first investigate whether your existing systems are suitable and connectable before promising anything. Not every system can be integrated, and we'll tell you honestly when that's the case.
FAQ

Questions about system integration

Can you connect any system?

Not guaranteed. We first investigate whether your existing systems are suitable and connectable, for example via an API, webhook, or a standard connector. Some systems, often older or closed ones, offer that only partially or not at all. We check this during the intake, before promising anything.

What's the difference between an API integration and a webhook?

A webhook pushes data immediately when something happens, for example a new form submission. An API integration actively fetches or sends data on request, for example a daily list of new customers. Which approach fits best depends on how the systems involved work and how quickly data needs to flow.

What happens if an integration fails?

Every integration includes error handling: if a system has an outage or is temporarily unreachable, data isn't lost, it's held, retried, or flagged for review. This is logged so you can see what happened.

What does connecting systems cost?

That depends on the number of systems, the complexity of the data flows, and whether it's a one-way or two-way sync. You get a fixed price after the intake, before anything is built.
