Custom Software Pricing in 2026: How Much Should You Budget?
LALucien Arbieu16 min read
Before even contacting an agency or a developer, one question almost always comes up first: how much does custom software cost? And it makes perfect sense to ask it first. It’s hard to move a project forward, convince management, or prioritize features without having a ballpark figure in mind.
The problem is that the honest answer usually starts with « it depends. » Custom software isn’t a product with a price tag on the shelf. It’s a project, and its cost varies based on what it needs to do, for how many users, at what level of quality, and with which integrations. Two projects that look similar on paper can end up with budgets that differ by a factor of four.
Yet « it depends » doesn’t help you budget. This article has one simple goal: to give you real price ranges, concrete budget examples, the factors that actually drive costs up, and a method for estimating your project before you even request a quote. By the end, you should be able to put a credible number on your idea.
How Much Does Custom Software Cost in 2026?
To cut straight to the point: custom software typically costs between €10,000 and €250,000, and sometimes considerably more. That’s a wide range, but it makes sense once you break it down.
A simple automation — one that merely connects tools or generates documents — can be handled for €3,000 to €4,000. A small internal tool designed to solve a specific problem starts at around €10,000 and goes up to €40,000. A SaaS MVP or a business application, with real functional logic and a back office, starts at around €20,000 and can reach €120,000 depending on scope. And a complex platform — with multiple roles, heavy integrations, advanced security, or artificial intelligence — regularly exceeds €150,000, and can reach €400,000 or more.
The table below provides a quick overview by project type. It’s the most useful reference to keep in mind before any cost estimation.

+ 1 to 3 months
Internal assistant, document search, scoring
These ranges are not fixed prices, but starting points. The rest of this article explains where the variation comes from, and more importantly, how to position your own project within this table.
Why Do Prices Vary So Much?
The gap is so wide because custom software isn’t measured in lines of code, but in complexity. And complexity hides in places you don’t always anticipate at the start of a project.
Functional scope is the first lever. An application that simply displays data costs far less than one that routes data between multiple roles, with validation steps, business rules, and edge cases. A « simple » workflow on paper quickly becomes a succession of scenarios to handle, and each of those scenarios represents time spent on design, development, and testing.
The number of users and roles also carries significant weight. A tool for a single team doesn’t have the same constraints as an application that must distinguish between an administrator, a manager, an operator, and an end customer. Each role adds permissions, specific screens, and an access control logic that must be designed and secured.
Then come integrations. Connecting your software to a CRM, an ERP, Stripe, a business API, or a single sign-on (SSO) system requires technical work that is often underestimated. An integration isn’t a simple plug-in: you have to handle data formats, errors, third-party service outages, and synchronization over time.
Security and compliance add another layer. Two-factor authentication, activity logs, granular permissions, audits, and backups are not optional extras for critical software. The more sensitive your data, the more this foundation costs — but it’s also what protects your business.
Data volume and real-time requirements also matter. Managing a thousand records is nothing like managing several million rows, large files, high-performance search, or instant updates. Beyond a certain threshold, the architecture itself changes, and the budget follows.
Artificial intelligence, finally, has become a cost factor in its own right. An internal assistant, intelligent document search, automatic classification, or document recognition (OCR) adds a technical layer that typically costs between €15,000 and €80,000 depending on the ambition.
On top of all this comes a more discreet but decisive variable: the expected level of quality. An MVP designed to test an idea doesn’t need the same robustness as a mission-critical product used daily by hundreds of people, or software subject to regulatory requirements. The higher the standard, the more time spent on testing, documentation, and reliability.
It’s the accumulation of these factors — not any single one — that explains why two projects « of the same type » can show very different budgets.

Rather than thinking in terms of a total price, it’s more accurate to think in phases. A software project almost always breaks down the same way: a scoping phase, a design phase, development itself, testing, deployment, and then maintenance. The budget is the sum of these phases, not just the « development » line item.
A very simple formula allows you to put a first number on the table:
Budget = number of project days × average daily rate × risk margin.
Let’s take a concrete example to make this tangible. Imagine a mid-sized business application. The project might break down as follows: around ten days of scoping, approximately eight days of UX/UI design, around forty-five days of development, ten days of quality assurance, five days of deployment, and eight days of project management. That comes to 86 working days.
At an average daily rate of €650, that amounts to €55,900 excluding VAT. Adding a 15% risk margin — a prudent figure for any software project — brings the realistic budget to approximately €64,285 excluding VAT.
That margin isn’t a superfluous comfort. It absorbs unforeseen events, user feedback, scope adjustments, and edge cases that only surface once development is underway. A quote with no risk margin is rarely a quote that holds to the end.
Four Concrete Budget Examples
Price ranges make much more sense when tied to real projects. Here are four typical cases, from the simplest to the most ambitious.
An internal tool for an SME. Budget between €15,000 and €40,000. This type of application typically includes authentication, simple roles, one or two business forms, a tracking dashboard, Excel exports, and a few email notifications. It’s a worthwhile investment because it replaces a shared spreadsheet or a manual process with a reliable, structured tool.
A B2B SaaS MVP. The budget most often falls between €30,000 and €90,000. It typically includes sign-up, subscription management via Stripe, a client portal, a dashboard, a back office, transactional emails, and basic analytics. The goal isn’t to cover everything, but to bring a credible first version to market — one capable of generating revenue and learning quickly. If that’s your situation, the article on SaaS development pricing in 2026 goes into greater detail.
A business application with integrations. Here the budget climbs to between €90,000 and €180,000. These are projects with multiple roles, validation workflows, a connection to an ERP or CRM, document management, reporting, activity logs, and granular access control. The complexity doesn’t come from any single spectacular feature, but from the chain of numerous business rules.
A complex platform. Beyond that, we’re talking €180,000 to €400,000 and more. These platforms include multi-tenant architecture, a single sign-on system, a public API, a rules engine, bulk imports, monitoring, high availability, and enhanced security. These are products built to last and to handle strong growth.
Positioning your idea against these four examples already gives you a far more reliable range than a number pulled from thin air.
Freelancer, Agency, or In-House Team: Which Should You Choose?
The cost of software depends not only on what it does, but also on who builds it. And each option has its own economic logic.
An existing SaaS product may be sufficient if your need is standard. It’s fast and inexpensive upfront, but you remain dependent on the tool’s limitations and recurring license fees that add up as your headcount grows. No-code, on the other hand, is excellent for testing an idea quickly, but quickly shows its technical limits once the project needs to handle complexity or high data volumes.
Custom development becomes relevant when the tool touches the core of your business. At that point, the choice comes down to a freelancer, an agency, or in-house hiring. The table below summarizes the trade-offs.
Option
Advantage
Limitation
Indicative budget
Existing SaaS
Fast, low initial cost
Inflexible, recurring licenses
€20 to €200 / user / month
No-code
Ideal for testing quickly
Technical limits, scalability
€1,000 to €30,000
Freelancer
Flexible, lower upfront cost
Risk of single-person dependency
€400 to €900 / day
Agency
Full team, methodology, continuity
Variable cost depending on agency size
€10,000 to €250,000+
In-house team
Full control
Long recruitment, high fixed cost
Salaries + management + lead time
For daily rate benchmarks, the market provides useful reference points. The median developer rate is around €535 per day, a fullstack profile around €530, React or Python specialists around €540, a DevOps profile around €605, and AI expertise around €760 per day according to the TJMetre 2026 benchmark.
A freelancer remains the most cost-effective option for a well-scoped project of reasonable size. Among agencies, the spread is significant: a small firm can start at around €10,000 to €20,000, whereas a large agency, with its overhead, rarely starts below €40,000.
Between the two, a more recent model has emerged: the freelancer-structured agency. The idea is to deliver what makes an agency valuable — a team, a methodology, and continuity over time — without the financial weight of a large organization. You get the rigor and multidisciplinary expertise of an agency, with a cost base closer to that of a freelancer. That’s PeakLab’s positioning.
In-house hiring only becomes cost-effective over the long term, once past the recruitment lead time and the fixed cost of a team. If you’re undecided, a fractional CTO can also help you make the call without hiring immediately.
Hidden Costs to Anticipate
Software doesn’t only cost money on the day it’s delivered. A significant portion of the real budget plays out after go-live, and that’s where many projects get caught off guard.
Maintenance is the first line item. It’s corrective first — handling bugs, dependency updates, and security patches. Then it’s evolutionary, because software that gets used always generates new requests. In practice, budget for annual maintenance of around 10 to 25% of the project’s initial cost.
Hosting is the second line item. A small project can be hosted for €50 to €500 per month. A growing SaaS, with more traffic and data, runs closer to €500 to €3,000 per month. And a mission-critical product, heavy on AI or high data volumes, regularly exceeds €3,000 per month. The topic deserves its own dedicated article: what budget to plan for maintaining a SaaS.
On top of that come third-party tools: email sending, SMS, payment, analytics, monitoring. Taken individually they seem minor, but their cumulative cost adds up. Security also represents a recurring cost, between audits, updates, and backups. Finally, documentation and knowledge transfer — often overlooked — prevent you from becoming locked into a vendor the day you want to switch.
One last hidden cost appears on no quote: technical debt. A project that’s poorly scoped upfront gets paid for later, in the form of slower and more expensive development. That’s why solid upfront scoping isn’t an expense — it’s a saving.
How to Reduce Costs Without Sacrificing Quality
Reducing a software budget doesn’t mean cutting corners on quality. It means making smart choices at the right time.
The most powerful lever is prioritization. Most projects want to do everything in the first version, when in fact a large portion of features can wait. Identifying the truly essential core and deferring the rest can cut the initial budget in half without reducing the value delivered.
The MVP approach follows the same logic: deliver a useful, limited version first, put it in users’ hands, then invest in what proves genuinely important. This approach avoids paying for features no one will use. That’s the whole point of a well-executed MVP and POC approach.
Choosing a standard tech stack rather than an exotic one also reduces costs, both in development and in future hiring. Similarly, reusing proven building blocks for authentication, payment, or email rather than rebuilding everything from scratch saves valuable time.
Finally, serious upfront scoping remains the most cost-effective investment of all. Every ambiguity resolved before development begins is a cost overrun avoided during development.
How to Calculate the ROI of Your Software
Custom software isn’t an expense — it’s an investment. And like any investment, it’s judged by its return. The right question therefore isn’t just « how much does it cost, » but « how much does it generate. »
Let’s take a simple example. Imagine a team of 10 people losing 30 minutes a day on a repetitive manual task: re-entering data, running exports, performing checks. Over 220 working days, that amounts to 1,100 hours lost per year.
At a fully loaded hourly cost of €45, those hours represent a loss of €49,500 per year. If the software that automates this task costs €80,000, the return on investment is reached in approximately 19 months. After that point, the tool costs nothing — it saves money.
And this calculation only accounts for time saved. It doesn’t measure errors avoided, team satisfaction, or opportunities seized more quickly. Thinking in terms of ROI — not just price — completely changes the way you look at a software budget.
The Checklist Before Requesting a Quote
Before contacting an agency or a freelancer, clarifying a few points upfront will save you time, money, and improve the accuracy of the quotes you receive:
The specific business problem the software must solve, and for whom.
The users and roles involved (administrator, manager, operator, customer).
The features that are truly essential in the first version, separated from those that can wait.
The existing tools the software will need to connect to (CRM, ERP, payment, others).
The expected level of security and compliance based on data sensitivity.
A rough budget range and a realistic target date.
How you will measure the project’s success once it launches.
The clearer these elements are, the more reliable and comparable the quotes you receive will be.
In Summary
The price of custom software is anything but arbitrary. It follows from a scope, a number of users and roles, integrations, a level of security, and a quality standard. Once those elements are defined, the ranges become readable: around €10,000 to €40,000 for an internal tool, €20,000 to €120,000 for an MVP or business application, and above €150,000 for a complex platform.
The most costly mistake isn’t spending too much — it’s scoping poorly. A project that’s well prepared, prioritized, and estimated methodically almost always costs less than one launched in the fog. And by thinking in terms of return on investment rather than simple expenditure, good software ends up paying for itself.
