How Much Does Custom Software Cost in 2026?
Honest pricing ranges for custom web apps, AI agents, and automation projects in 2026. What drives the number up, what to ask for in a quote, and which red flags to avoid.
"How much will it cost" is usually the first question on a discovery call. The honest answer is "it depends on three or four specific things", but that answer is useless without numbers. So here are the actual numbers we work with in 2026, from a senior-led studio that ships fixed-price projects every month.
The short answer
| Project type | Price (EUR) | Timeline |
|---|---|---|
| Simple automation (one workflow, one integration) | 5,000 to 12,000 | 1 to 2 weeks |
| AI chatbot with knowledge base | 6,000 to 15,000 | 2 to 4 weeks |
| Custom web application (dashboard, portal) | 15,000 to 50,000 | 2 to 4 weeks |
| Multi-channel e-commerce automation | 15,000 to 45,000 | 3 to 5 weeks |
| Production AI agent (autonomous multi-step) | 20,000 to 60,000 | 3 to 5 weeks |
| Custom SaaS or MVP closed beta | 30,000 to 80,000 | 3 to 6 weeks |
| Consulting workshop plus written roadmap | 1,500 to 3,000 | 1 week |
These are real ranges for a small specialized studio. Enterprise agencies (Accenture, Deloitte) charge 5 to 10 times more for the same work, mostly to cover their own overhead. Offshore shops often charge 30 to 50 percent less, but failure rates tend to be higher due to communication and project management gaps.
What actually drives the price up
Number of integrations
Every external system your software has to talk to (CRM, payment gateway, shipping API, ERP, accounting tool) adds a few days of integration work and a few weeks of edge case handling later. A standalone tool is 30 to 40 percent cheaper than one that talks to 5 other platforms.
This is the single biggest cost driver and the one most clients underestimate.
AI features
AI features (natural language understanding, document analysis, recommendation engines, agents) cost more than rule-based features because they need prompt engineering, evaluation harnesses, and retry logic for when the model has a bad day. A chatbot that answers 20 FAQs is 6,000 EUR. A chatbot that reads your CRM, qualifies leads, books meetings, and handles 5 languages is 15,000 EUR plus. Same "chatbot" label, very different scope.
The upside: AI features often deliver 5 to 10x the value of the rule-based alternative. The downside: they cost more upfront and the running cost is non-zero (API spend on Anthropic or OpenAI).
Custom UI versus internal admin panel
A polished customer-facing portal with brand colors, animations, and mobile responsiveness takes longer than an internal admin panel only your operations team will see. Both work. The internal tool is often where the actual money lives. Design polish on the customer-facing product is real value but it is a separate cost line.
Edge case handling
This is where most quotes lie. A vendor that gives you a 5,000 EUR price for "e-commerce inventory sync across 3 channels" has not thought about partial fulfillment, backorders, currency conversion, or marketplace-specific compliance. The first edge case will break the system and the second one will make the client switch it off.
We pad our quotes for edge case handling because we have shipped enough to know they exist. A quote that does not feel cheap looks expensive until week three of production, when the cheap one starts breaking.
What you should actually get for the money
A good fixed-price proposal includes:
- Problem statement (proves the team listened to you).
- Proposed solution (what they will build).
- Technical approach (stack, architecture, hosting).
- Milestones with dates, not just "4 to 6 weeks".
- Fixed price with payment schedule (30 percent upfront, 40 percent at midpoint milestone, 30 percent at delivery is common).
- What is included post-launch (30 days of support is the realistic floor).
- What is explicitly NOT included (the most important section, because it prevents arguments later).
- Source code ownership clause (you own everything; no lock-in).
If a proposal is just a number and a vague timeline, keep looking.
How to get the most value
Start with one process
Do not automate everything at once. Pick the one task that wastes the most hours, automate it, measure the time saved over a month, then expand. This is the difference between "this paid for itself in three months" and "we spent 40,000 EUR on a system nobody uses".
MVP first, polish later
A working tool that saves 10 hours a week is worth more than a perfect tool that launches three months late. Get the ugly version into production, then refine.
Fixed price, not hourly
Ask for fixed-price quotes. Hourly billing creates the wrong incentives: the slower the team works, the more they earn. Fixed price aligns interests: the team makes margin by shipping fast and well.
We do not bill hourly. We will turn down clients who insist on it. Not as a power move, but because hourly engagements predictably go over budget and end with both sides annoyed.
Ask about ROI
A 10,000 EUR project that saves 3,000 EUR a month pays for itself in about three and a half months. A project that saves under 500 EUR a month at this price probably is not worth doing yet. Run the math before you sign.
Red flags in vendor quotes
- "It depends" with no follow-up questions. They are not listening; they are stalling.
- 500 EUR quoted for a full custom web app. Either they are outsourcing to low-rate contractors or they have catastrophically underestimated the scope. Both end badly.
- 80,000 EUR plus for a simple dashboard. You are paying for a brand name, not better quality.
- No fixed-price option. They want open-ended billing because they cannot estimate, or because they have learned that "time and materials" produces higher revenue.
- No timeline commitment. Scope will creep indefinitely.
- They jump to tech stack on the first call without asking about your business. They are selling Next.js plus React not solving your problem.
Three questions worth asking on the first call
Three questions worth asking any vendor:
- "Show me 2 to 3 projects similar to what I need." If they cannot, they will be learning on your project.
- "Who specifically will write the code?" Some agencies pitch senior engineers and staff you with juniors. Get a name and a LinkedIn.
- "What is your post-launch support?" If the answer is "we can do that as a separate engagement", you have learned something important.
A 15 or 30-minute discovery call should leave you with a rough price range, a rough timeline, and an honest read on whether this vendor has actually shipped your kind of project. No commitment.
