How much does custom software cost in 2026? The short answer
Custom software development by a Hungarian team in 2026 typically costs 1.5–50 million HUF (€3,800–125,000 / $4,000–135,000): an internal business app runs €3,800–12,500, a customer portal €7,500–20,000, a mobile app €3,800–25,000, a custom CRM €30,000–125,000, and a full ERP €38,000–125,000+. Agency rates are €38–70 per hour; timelines run from 4 weeks to 12 months.
That is the short answer — the honest longer one starts with the fact that “how much does software cost”has no single correct number, just as “how much does a house cost” doesn't. What does exist is something more useful: price ranges by project type, so you know before requesting proposals whether your idea is a €5k, €20k or €60k undertaking. This article gives you exactly that: a price table for six project types, the five factors that move the price within each band, real 2026 hourly rates (Hungary vs Western Europe, the US and offshore), and the methods that genuinely cut costs.

delivery time depending on project type
The numbers below are based on our own pricing and on proposals we have seen across the Hungarian market in 2025–2026 (converted at roughly 395 HUF/EUR and 365 HUF/USD). They are not list prices — every project is different — but they are precise enough to flag the two suspicious extremes: the unrealistically cheap quote that ends in a half-finished system, and the overpriced one.
Price table: cost by project type
These six categories cover the vast majority of custom development requests we see from SMEs. Prices are for a complete, delivered system — specification, testing and training included.
| Project type | Price range (2026) | Timeline | What you get |
|---|---|---|---|
| Internal business app | €3,800–12,500 | 4–10 weeks | Work orders, registries, approval workflows — replacing the spreadsheet chaos |
| System integration | €3,800–15,000 | 3–8 weeks | Connecting two existing systems: e-commerce–inventory, CRM–invoicing, tax authority APIs |
| Customer / partner portal | €7,500–20,000 | 8–14 weeks | Self-service login for clients: order tracking, documents, online transactions |
| Mobile app | €3,800–25,000 | 2–6 months | iOS + Android from one codebase, with its own backend and admin panel |
| Custom CRM | €30,000–125,000 | 3–6 months | A system built around your actual sales process, with integrations |
| Custom ERP | €38,000–125,000+ | 6–12 months | Full business management: inventory, production, finance, HR in one system |
A few notes on the table. The internal business app is the most common entry project: digitising one concrete process (work orders, asset tracking, leave management). It stays cheap because integrations are few and the design is functional. System integrationpricing depends almost entirely on the quality of the two endpoints' APIs — a well-documented invoicing connection takes weeks, while mapping a 15-year-old, undocumented legacy ERP can eat weeks before a line of integration code is written.
The two big-ticket items are CRM and ERP. At the €30,000 end, a custom CRM means a focused system with a handful of modules; above €75,000 you are usually looking at heavy integration work (telephony, invoicing, e-commerce, marketing automation) and a complex permission model. For ERP, never compare build prices alone — compare the 5-year total cost of ownership including licensing, operations and extensions.
For mobile apps, the bottom of the band is a simple app connected to an existing backend; the top is a full product with its own backend, payments and push notifications. Technology choice (cross-platform vs native) is a major cost factor too — see our mobile app development cost breakdown.
The 5 factors that actually drive the price
Why does one customer portal cost €7,500 and another €20,000? It is not the agency's mood. Five factors each have the power to move the price by 30–100% — when comparing proposals, these are the questions to ask about what the price includes.
1. Scope: how many features and processes
The strongest factor. An “order management module” can be 5 screens (list, details, status change, search, export) or 25 (quote-to-order, partial shipments, credit notes, courier integration…). Rule of thumb: each well-defined feature module of medium complexity costs €750–2,000. Scope should not be cut — it should be prioritised, which is what the MVP section below is about.
2. Integrations: what the system must talk to
Every external connection — invoicing platforms, tax authority reporting, e-commerce, banking APIs, telephony, ERP — typically adds €750–3,800 depending on API quality. Four integrations can easily double an otherwise simple system. The good news: experienced teams have proven, reusable modules for common endpoints, which is one of the quiet advantages of hiring a team that already ships regulated integrations (in our case, Hungarian NAV real-time invoicing, GDPR and NIS2 compliance come as standard).
3. User count and permission levels
It is not the number of users that raises the price — it is the roles. If agents, team leads, finance and external partners each see and approve different things, the number of screens and test cases multiplies. A two-level permission model (admin + user) is baseline; a four-to-five role system with approval chains adds 20–40% to the build.
4. Design and user experience
For internal tools, a clean, functional UI built on a proven component system is enough — and fast. For customer-facing products (portals, mobile apps), design is a branding and conversion issue: budget €1,300–5,000 for a proper UX phase with prototyping and testing. This is not a luxury — customers simply won't use a portal that fights them.
5. Support, operations, warranty
Handover is not the end of the story. Annually, expect 15–20% of the build cost for maintenance: hosting, security patches, bug fixes, minor changes. This is the most common trap in proposal comparison: one price includes a 12-month warranty and an SLA, the other invoices every post-launch fix separately. Always compare 5-year total cost, never the project price alone.
Hourly rates in 2026: Hungary vs Western Europe, US and offshore
Rates are the second most frequent question after price — and the most frequently misread number. Here is the 2026 landscape from a Central European vantage point:
| Who builds it | Hourly rate (2026) | When it makes sense | The risk |
|---|---|---|---|
| Hungarian freelancer | €23–45 | Small, well-scoped task; you have in-house technical capacity to take over the work | One person = bus factor. Illness, overcommitment, disappearance — and nobody reviews the code |
| Hungarian agency | €38–70 | Business-critical systems needing design, testing, warranty and multi-year operations | Higher rate — in exchange for a team, continuity and contractual accountability |
| Western European agency | €90–160 | When your client contractually requires a local vendor | The same technology at 2–3× the price; the gap is wage levels, not quality |
| US agency | $120–250 | US-market products needing same-timezone, on-site collaboration | The highest total cost; senior talent often subcontracted anyway |
| Offshore (Asia) | $20–40 | High-volume, precisely specified, non-time-critical work | Timezone gaps, communication friction, rework — effective cost often lands at nearshore levels |
Two lessons follow. First: a low hourly rate is not a low project cost. A €30/hour developer who needs twice the hours ends up more expensive than a €55/hour senior — and the difference bites hardest not at delivery, but two years later at the first major change request. Second: on a fixed-price project the rate is only an internal calculation figure; what protects you is the fixed scope, the milestones and the warranty.
The Hungary–Western Europe price gap is structural, not a currency blip — which is why a growing share of German, Austrian and Dutch companies build from Budapest. We dissected the numbers in Hungary vs Western Europe development pricing.
How to reduce the cost: MVP and phasing
The good news: within the bands above, the final figure is largely in your hands. Not through haggling — that buys you lower quality — but through structuring the project intelligently. Four methods that demonstrably work:
- Start with an MVP. Instead of the full vision, build the 3–5 features that 80% of daily work depends on. That is typically 30–40% of the full-scope budget and yields a live system in 6–10 weeks — which then tells you what is actually needed. Full methodology in our MVP development guide.
- Phase the project. Instead of one €60,000 CRM project, run three €15,000–25,000 phases, each ending with a working, usable system. Risk drops with it: if phase one misses expectations, two-thirds of the budget is still in your pocket.
- Build on proven components. Authentication, permissions, payments, invoicing integrations — none of this should be written from scratch. An experienced team assembles proven building blocks and spends custom development time only on what is genuinely unique to your process: a 20–35% cost difference for the same outcome.
- Arrive with a precise process description.Not a technical specification — that is the developer's job — but a clear account of who does what, in what order, today, and what should change. Every ambiguity resolved mid-development costs roughly twice as much as one settled up front.
Where you should not save: testing, data migration and training. These three are the usual casualties of price negotiations — and then the first month after go-live reveals that the customer database migrated badly and nobody can use the new system.
Summary and frequently asked questions
How much does a simple custom application cost?
A well-scoped internal business app — work orders, inventory records, approval workflows — built by a Hungarian team runs €3,800–12,500 ($4,000–13,500) and ships in 4–10 weeks. The price stays low because there are few integrations, one or two user roles, and the design is functional rather than brand-driven.
What are software development hourly rates in Hungary in 2026?
Hungarian freelance developers charge €23–45 per hour, established Hungarian agencies €38–70 per hour. For comparison, Western European agencies bill €90–160 and US agencies $120–250 for the same technology stack. On fixed-price projects, though, the total cost and accountability matter more than the rate.
How much does a custom CRM cost?
A custom CRM built in Hungary costs 12–50 million HUF (€30,000–125,000 / $33,000–135,000) with a 3–6 month timeline. The lower band covers a focused system with a few modules; the upper band reflects heavy integration work (telephony, invoicing, e-commerce, marketing automation) and complex permission structures.
Why are custom software price ranges so wide?
Because five factors drive the price, and each can multiply it: feature scope, number of integrations, user roles and permission levels, design ambition, and the expected level of support and operations. Two systems that look similar on the surface can differ in price by a factor of five for these reasons.
How long does custom software take to build?
A small internal app or integration takes 4–10 weeks, a customer portal 8–14 weeks, a mobile app 2–6 months, a custom CRM 3–6 months, and a full ERP 6–12 months. Delays usually come from the client side — late content, decisions, and testing feedback — rather than from development itself.
What annual maintenance cost should I budget for?
As a rule of thumb, 15–20% of the build cost per year. That covers hosting, security updates, bug fixes and minor changes. For a €25,000 system, that means €4,000–5,000 annually. Any vendor promising zero maintenance either isn't operating the system or will invoice you later.
Is off-the-shelf software cheaper than custom?
In the short term, almost always. Over 3–5 years the picture often flips: SaaS fees grow per seat and force your processes into the tool's mold, while custom software is a one-time investment built around your workflow with no per-user licensing. The tipping point is typically 10–20 users plus at least one core process the boxed product can't follow.
How can I reduce custom development costs?
Four proven levers: start with an MVP (30–40% of the full-scope budget covers about 80% of daily work), split the project into phases that each ship a working system, let the team build on proven pre-built components, and arrive with a precise process description — vague specifications are the most expensive line item in any project.
