AI agent integrations: what actually connects to what in a Finnish SME
Integrations are 80% of the work
The AI part of an AI agent is often the easy part. The hard part is connecting it to the tools that actually run your business. Below is a plain-language field guide, based on real Finnish SME stacks.
Tier 1: plug and play
These have modern REST APIs, official SDKs, and OAuth. An agent connects to them in hours, not days.
- Email & calendar: Gmail, Google Calendar, Outlook, Microsoft 365
- CRM: HubSpot, Pipedrive, Salesforce
- Chat & docs: Slack, Teams, Notion, Google Docs
- E-commerce: Shopify, WooCommerce, Stripe
- International accounting: Xero, QuickBooks
If your stack is mostly Tier 1, integration cost stays low.

Tier 2: Finnish essentials
These have proper APIs but require more auth setup, sometimes rate limits, and often need a Finnish-speaking partner to navigate the docs.
- Procountor: full API, good docs, needs a partner account
- Netvisor: API access, some endpoints paid extras
- Visma / Fivaldi: API works, but scoping differs by module
- Fennoa: modern API, straightforward
Plan an extra week of setup versus Tier 1. Costs go up €500 to €1,500 per integration.
Tier 3: possible with workarounds
- Older on-premise ERP (Passeli, older Fivaldi): often needs a nightly export to CSV that the agent reads
- Bank statements: usually via PSD2 aggregators like Enable Banking, not direct
- Old scheduling systems: often need an email-triggered workflow instead of a real API
- Booking software without APIs: agent works on the export, not live
Tier 4: don't try (yet)
- Any Windows program without any way to export data
- Systems where credentials must be entered every session with a hardware token and no service account
- Systems whose vendor forbids automated access in the terms of service
::: callout The one question that saves a lot of money
Before commissioning an agent, ask each tool vendor two things: "Do you have an API?" and "Can we get a service account or app token that doesn't require a human to log in?" If the answer to either is no, tell us before the quote.

What "integration" actually costs
A single Tier 1 integration is usually rolled into the base agent price. Each additional Tier 2 integration adds €500 - €1,500. Tier 3 workarounds add €1,000 - €3,000 depending on how ugly the source system is.
Two real examples
Small consulting firm
- Gmail (Tier 1) + HubSpot (Tier 1) + Notion (Tier 1) + Xero (Tier 1)
- Total integration cost: rolled into base €3,200 build
- Agent handles: inbox triage, meeting notes, invoice drafting
Small e-commerce brand
- Shopify (Tier 1) + Klaviyo (Tier 1) + Procountor (Tier 2) + Posti API (Tier 2)
- Total integration cost: €3,500 base + €1,800 for two Tier 2 systems = €5,300 build
- Agent handles: order questions, refund processing, invoice sync to accounting
The step you can take today
Make a list of every tool your team logs into during a week. Note the vendor. Send it in when you request a quote. That single list cuts one full round of back-and-forth from the process.

Frequently asked questions
Which systems does an AI agent connect to easily?
Tools with a modern API and authentication: Gmail, Outlook, Slack, Notion, HubSpot, Pipedrive, Shopify, WooCommerce and Stripe. With these, connecting is hours of work rather than weeks. The trouble starts only where a system has no API at all.
What if we use Finnish accounting software?
Most Finnish packages do have an API, but it is narrower than the international tools and the documentation is thinner. Connecting works, but it is a piece of work rather than a ready-made link. Settle this before the agent price is fixed.
What does an integration really cost?
Connecting to an existing API is typically a small share of the project. A system with no API costs several times more, because data has to move by workaround and the result is more fragile. If one of your systems falls in that category, consider scoping the agent around it.
