System integration and APIs for business

We connect the software you already use, so data entered once reaches every place it is needed.

The problem

The same data in several places

When systems don't talk to each other, someone has to bridge them by hand: exporting, copying and pasting. That costs time and causes errors.

  • The same data typed into several programs
  • Spreadsheet exports and manual imports
  • No single place with up-to-date data
  • Retyping errors
  • Reports stitched together from several sources

The solution

What we integrate

You don't always need to replace a system. Often it is enough to connect what the company already has.

  • Software integrations via API
  • Data exchange between databases
  • Scheduled or event-driven synchronisation
  • File imports and exports
  • E-mail notifications and reports
  • Dashboards combining several data sources
  • Changes to existing software

Approach

How we approach integration

An integration runs in the background, so it has to be predictable. That is why we start with a data-flow map, not with code.

  • First the map: where data comes from, where it goes and who changes it
  • Error handling and an event log — you know what happened and when
  • Secure storage of access keys
  • Staged roll-out, tested before it touches production data

Process

How we work together

  1. Conversation and scope which systems, which data, how often
  2. Data-flow map one source of truth for each piece of information
  3. Connection and tests the integration runs on test data first
  4. Go-live in stages, with results checked
  5. Maintenance monitoring and further work if you want it

Technology

What we use

  • API integrations
  • PostgreSQL and SQLite databases
  • Python and Node.js
  • Automatic reports and e-mail notifications
  • Monitoring and backups

What it costs

Scope and price depend on the number of systems and whether they offer an API. Smaller automations start at PLN 290; larger projects are quoted once we know the scope. STTELLA hosting — from PLN 29 a month.

FAQ

Frequently asked questions

What if our software has no API?

We look for another way to exchange data, e.g. files or the database — as long as it can be done safely. If it can't, we say so.

Will the integration disrupt our work?

We roll it out in stages and test it on test data before it touches production data.

Who maintains the integration afterwards?

We can maintain and monitor it. STTELLA hosting starts at PLN 29 a month.

Do we need to replace our current systems?

Usually not. We work with existing systems and use what you already have instead of replacing everything.
