AI Software Development Cost: What You'll Actually Pay in 2026
Date Published
AI-assisted custom software from Globaprom costs €1,500 to €25,000 as a fixed price, depending on project size, against $100–200 per hour with no ceiling at a traditional agency. A workflow automation sits at the low end. A full multilingual platform sits at the top.
That range is wide because "AI software development" covers everything from a single automated form to a customer-facing platform in five languages. This article breaks the number down by project size, shows the traditional-agency math it replaces, and explains what pushes a quote up or down. It also covers the part most pricing pages skip: why the cheapest AI-generated quote is sometimes the most expensive one, once you count what happens after launch. For the bigger picture of what AI-assisted development is and where it differs from unreviewed vibe coding, see our hub on vibe coding and AI-assisted development for business.
Why AI-Assisted Development Changed the Cost Structure
Custom software used to cost what it cost because of typing time. An engineer wrote every line, so the price scaled with hours, and hours scaled with the size of the codebase. AI coding tools broke that link. A senior engineer can now direct an AI model to generate most of a feature's code in minutes, then spend their own time on the part that still needs a human: architecture decisions, review, testing, and the judgment calls a model cannot make.
That is a change in build time, not a change in what gets built. The specification still has to be right. The code still has to be read, tested, and secured before it touches a customer or a payment. What compresses is the distance between "we understand what you need" and "here is a working, reviewed application," from months down to weeks.
This is the distinction the vibe coding hub is explicit about: speed comes from the AI generation step, not from skipping the engineering around it. A quote that is cheap because nobody reviewed the code is a different product from a quote that is cheap because AI compressed the writing while a senior engineer still checked every line. The rest of this article prices the second kind, because it is the only kind you can run a business on.
What Custom Software Costs, By Project Size
Globaprom quotes three fixed-price packages. Every one includes scoping, human review of all generated code, deployment, documentation, and full code ownership: you get the repository, not a subscription.
Workflow Automation: €1,500–4,000. This covers a single automated process end to end: document assembly, data re-keying between two systems, an approval chain, a scheduled report. It includes up to two system integrations plus error handling, retries, logging, and monitoring. Typical delivery is 2–3 weeks from an approved scope.
Custom Web App: €4,000–12,000. This is the tier for the tool your team currently forces into spreadsheets or an almost-right SaaS product: a booking system, a quoting tool, a client portal, an internal dashboard. It includes a full web application with authentication and role-based permissions, a responsive interface plus an admin area, and up to two integrations with your existing systems. Typical delivery is 3–6 weeks.
Multilingual Platform: €9,000–25,000. This tier adds everything a customer- or partner-facing product needs to run in more than one language: localized interfaces, a translation pipeline connected to professional translators, and multi-currency, locale-aware dates and formats. Typical delivery is 5–8 weeks.
Most projects fit inside one of these three bands. If yours sits between them or goes beyond the top one, the packages still work as a calibration point: describe what you need and request a fixed-price quote for the exact figure.
What a Traditional Agency Would Charge for the Same Build
Traditional agencies bill $100–200 per hour against an open-ended scope. A modest custom web app, the kind Globaprom quotes at €4,000–12,000, typically runs 300 to 600 hours of agency time once discovery, build, QA, and revisions are counted. At $150 an hour, the middle of that band, that is $45,000 to $90,000, plus the schedule risk of an hourly clock that keeps running through every misunderstanding and revision.
The gap is not a discount on quality. It is a different cost structure. AI-assisted development removes hours from the typing part of the job and keeps them in the parts that protect you: scoping, review, testing, and security. A fixed price also moves the delivery risk off your budget. If a build runs long, that is Globaprom's problem to absorb, not an extra line on your invoice.
What Actually Moves Your Price Up or Down
Three factors explain most of the difference between a quote at the bottom of a package range and one at the top:
Integrations. Every system your software has to talk to, an ERP, a CRM, a carrier network, a payment gateway, adds scope. A clean, documented API costs far less to connect than a legacy format like EDI or a manual file drop.
Localization. Extra languages add content and testing work, not new architecture, because Globaprom builds every project i18n-first from day one. That makes each additional language a linear cost rather than the retrofit project it becomes on a codebase that was never built to support it.
Compliance. GDPR data handling, PCI DSS scope on anything that touches payments, and audit-trail requirements are all buildable. Each one gets scoped and priced explicitly upfront rather than discovered halfway through the build, which is where compliance work gets expensive on any project, AI-assisted or not.
User roles, data migration volume, and offline-first mobile requirements move the number too. None of it is hidden: it shows up in the written scope you approve before any code gets generated, which is the same scoping discipline described in full in how we scope, build, and review.
Why the Cheapest AI-Generated Quote Can Cost More Later
Not every low quote in this market is the same kind of low. A vendor that lets an AI model generate an application and ships it without review can undercut any of the figures above, because they skipped the part of the job that costs money: reading the code.
That gap shows up later, not on delivery day. Veracode's 2025 GenAI Code Security Report found that 45% of AI-generated code samples contained known security vulnerabilities (Veracode, 2025). In a reviewed build, an engineer catches an exposed API key or a missing validation check before launch. In an unreviewed one, it ships, and the fix arrives as an incident instead of a line comment. Our guide on is AI-generated code safe walks through the specific vulnerability classes this stat covers.
Unreviewed code also gets more expensive to touch over time, not less. CISQ's 2022 report on the cost of poor software quality put the annual cost of bad code in the US at $2.41 trillion, driven largely by the extra time it takes to fix, extend, or secure software nobody fully understands (CISQ, 2022). A codebase with no human author who can explain it behaves the same way at any size: every new feature becomes a negotiation with code nobody trusts.
This is the same line the vibe coding hub draws between pure vibe coding and AI-assisted development, and it is worth restating in cost terms: the AI-generation step is not where the risk sits. The review step is where the cost of that risk gets removed, and it is the one step a rock-bottom quote is most likely to have skipped. We cover exactly what that review step catches, and why it changes the economics, in human review of AI-generated code.
Frequently Asked Questions About AI Software Development Cost
How much does AI software development cost?
Globaprom's fixed-price packages run €1,500 to €25,000, depending on project size: workflow automations at the low end, full multilingual platforms at the top. A traditional agency billing $100–200 per hour for comparable scope typically lands well above that range once discovery, build, and revisions are counted.
Is a fixed price actually final, or does it grow with revisions?
It is final against the scope you approved. If you change the scope mid-project, the change gets quoted explicitly and you decide before any extra cost is incurred. The original number never grows silently, which is the point of fixing it in the first place.
What's included in the price, besides the code?
Every package includes scoping, human review of all generated code, deployment, documentation, and full code ownership. You receive the repository and can move maintenance in-house at any time, with no license fees or dependency on us to keep it running.
Why is AI-assisted development cheaper than a traditional agency?
Because AI generates most of the code in minutes instead of hours, engineers spend their time on review, testing, and architecture instead of typing. The build compresses from months to weeks, so the price reflects weeks of engineering, not months of billed hours.
Does a lower price mean lower quality?
Not with a reviewed build: the price drops because AI compresses writing time, not because review gets skipped. It does mean lower quality when a vendor skips the review step entirely, which is the gap between AI-assisted development and unreviewed vibe coding.
How do I get an exact number for my project?
Tell us what you need built. After a short scoping call, you receive a written scope, one fixed price, and a delivery date measured in weeks. The quote itself is free and carries no obligation.
