Integration Development

When your CRM doesn't talk to your ERP, your e-commerce platform doesn't sync with your warehouse, or your team is manually copying data between systems — that's lost time and lost money. We build integrations that eliminate the gap.

What we integrate

  • CRM integrations — HubSpot, Salesforce, Pipedrive, and custom CRM systems connected to the rest of your stack
  • CSI Helsinki — As an official integration partner, we build specialised integrations for law firms using CSI Helsinki's practice management platform
  • E-commerce integrations — Connect your online store with inventory, accounting, fulfilment, and marketing tools
  • ERP & accounting — Sync data between your operational systems and financial tools automatically
  • Custom API integrations — If it has an API, we can connect it. We build reliable, documented integrations between any two systems

No-code or custom code — choose what fits

Not every integration needs to be custom-built. Sometimes Make, Zapier, or n8n is the right answer — it's faster to set up, easier for your team to manage, and perfectly sufficient for the job.

We'll always recommend the simplest solution that genuinely solves your problem. If that's a no-code platform, we'll configure it, document it, and train your team to own it. If you need precision and reliability that only custom code can provide, we build that too.

Official CSI Helsinki partner

We are proud to be an official integration partner for CSI Helsinki — the leading practice management system for law firms in Finland. This means we have deep knowledge of CSI Helsinki's API and architecture, and we've built production integrations connecting it with document management systems, CRM platforms, time tracking tools, and accounting software.
