The honest answer
Custom AI development costs anywhere from a few thousand euros to tens of thousands, depending on what you're building. That's a wide range because "AI development" is a wide category — the same way "construction" covers both a garden shed and a hospital.
Here's how we break it down at DK Studio, based on 14+ products we've built since September 2025.
Pricing by project type
| Project Type | Typical Range | Timeline | Examples |
|---|---|---|---|
| Single AI Agent | Low thousands | 3-7 days | Email processor, lead scorer, content generator |
| Agentic Workflow | Mid thousands | 1-2 weeks | Multi-step operations pipeline, automated reporting system |
| MVP / Web App | Mid to upper thousands | 2-4 weeks | SaaS platform, client portal, marketplace |
| Complex Multi-Agent System | Upper thousands to low tens | 3-6 weeks | Enterprise dashboard with OCR, multi-source data pipeline, decision engine |
What drives the cost up
- Number of integrations — Each external system (CRM, ERP, payment processor, email provider) adds complexity. Connecting to 2 systems is straightforward. Connecting to 10 with data flowing between them requires careful architecture.
- Decision complexity — A workflow that follows simple rules is quick to build. A system that needs to interpret documents, make judgment calls, or handle 20 different edge cases requires more engineering.
- Data volume — Processing 100 records per day is different from processing 100,000. High-volume systems need optimization, queue management, and monitoring.
- Compliance requirements — Healthcare, finance, or legal applications may need audit trails, data encryption, access controls, and compliance documentation.
- User interface — If the system needs a dashboard, admin panel, or client-facing portal, that adds frontend development time.
What drives the cost down
- Clear scope — The more precisely you can define what the system should do, the faster we can build it. Vague requirements cause iteration cycles that add time and cost.
- Standard integrations — If your tools have good APIs (Slack, Google Workspace, HubSpot, Stripe), integration is fast. Legacy systems with no API add cost.
- Starting small — Build one workflow first. Prove the ROI. Then expand. This is almost always cheaper than trying to automate everything at once.
DK Studio vs other options
| Option | Upfront Cost | Ongoing Cost | You Own the Code? |
|---|---|---|---|
| DK Studio | Fixed project fee | Hosting only | Yes, 100% |
| Enterprise vendor (UiPath, etc.) | High implementation fee | Annual licensing (6 figures+) | No — vendor platform |
| Freelancer | Hourly (variable) | Maintenance hourly | Usually, but quality varies |
| In-house team | Salaries (very high) | Salaries (ongoing) | Yes |

How to think about ROI
The question isn't "can I afford AI development?" It's "can I afford not to?"
If your team spends 20 hours per week on a process that an agentic workflow can handle, that's 20 hours of salary, benefits, and opportunity cost — every single week. Most of our projects pay for themselves within 1-3 months through time savings alone.
