How Much Does AI Integration Cost in 2026?

Alessandro Afloarei·

AI integration costs range from €5,000 for a fixed-price 2-week sprint to €300,000+ for a 6-month agency engagement. For most B2B SaaS companies with a defined use case, a €5,000 sprint delivers a production-ready RAG pipeline, agent workflow, or LLM-powered feature in 2 weeks.

If you're a SaaS founder exploring AI features, the first question is usually "what's this going to cost me?" The answer depends entirely on who you hire, how the project is scoped, and whether you actually need what's being sold.

I've been building AI integrations for B2B SaaS products for the past few years. Here's what I've seen across the market — and what I charge.

The typical cost range

AI integration pricing falls into three buckets:

Agencies and consultancies: €50,000 – €300,000+ (industry averages from Clutch and Goodfirms consultancy data)

Large firms typically run 3–6 month engagements. They'll staff a team of 3–5 people, run discovery workshops, produce architecture documents, and eventually build something. The bulk of the cost goes to project management, coordination, and overhead. You're paying for the process, not just the code.

For enterprise companies with complex compliance requirements, this sometimes makes sense. For a 20-person SaaS company that needs a RAG pipeline, it almost never does.

Freelance AI engineers: €50 – €150/hour (Upwork average rates, 2024-2025)

Hourly freelancers can be effective, but the economics are tricky. A mid-level AI engineer at €100/hour working 4 weeks full-time costs €16,000. Senior engineers in Western Europe charge €120–€150/hour (based on 2024 StackOverflow Developer Survey and Honeypot EU Tech Salary Report), putting a month of work at €19,000–€24,000.

The problem isn't the rate — it's the scope creep. Hourly billing incentivizes exploration over shipping. I've seen "2 week" projects stretch to 3 months because there was no pressure to converge on a solution.

Fixed-price sprints: €5,000 per sprint

This is how I work. A 2-week sprint costs €5,000 and delivers one production-ready AI feature. RAG pipeline, agent workflow, LLM-powered classification — scoped, built, tested, and deployed.

The fixed price forces clarity. You and I agree on the deliverable before I write a line of code. If the scope you need is larger, I run two sprints back-to-back at €10K total — not a custom quote.

Why most projects are over-scoped

The biggest waste in AI integration isn't technical — it's organizational. Companies spend €100K+ because they skip the most important step: figuring out what they actually need.

Here's what I see repeatedly:

  • "We need an AI strategy" — No, you need one feature that solves a specific user problem.
  • "We want to build our own model" — No, you want to call an API and wrap it in good UX.
  • "We need a 6-month roadmap" — No, you need to ship something in 2 weeks and see if users care.

Most AI features in B2B SaaS are variations of a few patterns: retrieval-augmented generation (RAG), structured data extraction, classification, or workflow automation. These are well-understood problems. The engineering is straightforward when the scope is clear.

What you actually get for €5,000

In a 2-week sprint at €5,000 flat, I typically deliver:

  • Architecture and integration plan — How the AI feature fits into your existing stack
  • Implementation — Production code integrated into your codebase, not a separate prototype
  • Vector store / embeddings setup — If RAG is involved, this includes ingestion pipelines and search
  • Prompt engineering and testing — Optimized prompts with evaluation against real data
  • Deployment and monitoring — The feature ships to production with observability built in

What you don't get: a 40-page strategy document, weekly status meetings, or a Gantt chart. The deliverable is working software.

How to evaluate if you need AI integration

Before spending anything, ask yourself:

  1. Is there a specific user problem? "Our customers can't find answers in our docs" is a real problem. "We should add AI" is not.
  2. Do you have the data? RAG needs a corpus. Classification needs labeled examples. If your data is a mess, clean it up first.
  3. What's the business impact? If the feature doesn't reduce churn, increase activation, or unlock a new pricing tier, it might not be worth building yet.
  4. Can you maintain it? AI features need ongoing tuning. Make sure someone on your team can own it after delivery.

If you answered yes to all four, you're ready. If you're unsure about any of them, a 30-minute conversation can usually sort it out.

The bottom line

AI integration doesn't have to cost six figures. For most B2B SaaS companies, the right approach is a focused sprint that ships one feature and proves the value before committing to more.

The €5,000 question isn't "can we afford it?" — it's "do we know exactly what we want to build?" If you do, two weeks is enough.
