# How much does custom business software cost in 2026?

At C-Esium, a complete custom internal software starts from AED 200,000 excluding VAT, and a focused project from AED 40,000 (from €50,000 and €10,000 for clients in France). Beyond that there is no price grid: the budget depends on your size and daily users, your sites and business units, your current tools and the scope. The exact price is set after the assessment in a firm quote, paid in milestones, and you own the software at the end of the project.

Custom business software has no list price: it has a scope. This guide gives you C-Esium’s price references for clients in the UAE and in France, what pushes the bill up or down, and a method to compare it honestly with a SaaS subscription over five years.

## How much does custom business software cost at C-Esium?

A complete internal software starts from **AED 200,000** excluding VAT (**€50,000** for clients in France). Beyond that there is no price grid, and that is deliberate: two companies of the same size can have very different needs. A company of about fifteen people can, from AED 200,000, bring its key operations together in a single tool. A company with several business units, hundreds of daily users and data scattered across many tools will need a much larger budget.

That is why the price is set after the assessment, once your situation is known. During a half-day workshop, on site or by video, we follow the real journey of a case, list your tools and your data, then quote a written scope.

On timing: a V1 on a focused first scope (for example, from customer request to invoice) is delivered in **1 to 2 months**. Software covering the whole company takes **from 6 months to more than a year**, delivered in batches. AI is built in from the V1.

## Can you start with a smaller budget?

Yes. To start smaller: a focused project, from AED 40,000 — a single module as a V1, an AI connector on your current tools, automations between your tools or a mobile app for field teams. It can later grow into a complete internal software. For clients in France, a focused project starts from €10,000 excluding VAT.

A single module (CRM, scheduling or quotes and invoicing) is delivered in 1 to 2 months. The ownership rules are the same as for a complete software: you own the code. Here too, the exact price is set after the assessment, in a firm quote. Details are on the [focused project](https://c-esium.com/en/focused-project/) page.

## What makes the price vary?

| Factor | Why it matters | The question to ask yourself |
| --- | --- | --- |
| Company size and daily users | More people using the tool every day means more roles, permissions, training and higher reliability requirements | How many people will use the tool every day, and in which roles? |
| Sites, branches and business units | Each entity adds its own rules, approval flows and the need for a consolidated view | Do all your branches or business units work the same way? |
| Current tools and scattered data | Data spread across spreadsheets and software needs migration, cleaning, de-duplication and integrations | How many tools and files hold your data today? |
| Scope | Each process covered adds screens, business rules and tests | Do you start with one journey (customer request → invoice) or with the whole company? |
| Depth of the software | Business rules, automations, dashboards: the more the tool frames the work, the more there is to build | Which rules should the tool apply instead of your teams? |
| Integrations | Accounting, payroll, telephony and SMS, technical software: each connection must be designed and tested | Which tools stay in place? |
| AI features | The V1 includes dictated reports, a copilot and MCP access; smart quoting or team allocation proposed by AI are later developments | Which decisions should the AI prepare for you? |
| Regulatory constraints | Health data or specific invoicing requirements can add a hosting arrangement or an integration to the scope | Does your activity handle sensitive data or follow specific invoicing rules? |

## How is a project paid for?

-   **In milestones**: kick-off, mock-ups, screen approval, delivery. You pay for what you see progress.
-   **In batches**: a useful V1 quickly, then successive batches following the roadmap set at scoping.
-   **No licence**: no per-user subscription, no royalty on the code assigned to you.
-   **Optional maintenance**: a monthly package, if you want C-Esium to maintain your software after delivery.

The first contact is a 30-minute call. For a qualified project, the first call and the half-day assessment workshop — on site or by video — are free: nothing is invoiced before the project starts. For a first order of magnitude based on the size of your company, use the [online estimate](https://c-esium.com/en/contact/#estimate): it does not replace the assessment.

## Over 5 years, is it more expensive than a SaaS subscription?

Compare full costs, on the same scope and over the same period. The method fits in two formulas:

-   **SaaS cost over 5 years** = sum of the annual subscriptions (users × monthly price × 12, with the annual increase) + set-up and configuration + paid modules and connectors + cost of workarounds (re-keying, parallel spreadsheets).
-   **Custom software cost over 5 years** = build + 5 × (hosting + maintenance + further developments) + cost of the remaining workarounds.

**Worked example — entirely hypothetical.** The values below are neither vendor prices nor C-Esium rates: replace them with your own.

| Variable (assumption) | Value used |
| --- | --- |
| Users | 40 |
| SaaS subscription per user per month | AED 300 |
| Annual subscription increase | 5% |
| SaaS set-up and configuration | AED 80,000 |
| Paid modules and connectors | AED 12,000 per year |
| Custom software build | AED 450,000 |

SaaS side: 40 × 300 × 12 = AED 144,000 in year one. With a 5% increase each year, the subscriptions add up to about **AED 795,700** over 5 years. Adding set-up (AED 80,000) and connectors (AED 60,000), the direct cost reaches about **AED 935,700**.

Custom side: AED 450,000 to build. Custom software stays cheaper over 5 years as long as hosting, maintenance and further developments cost less than (935,700 − 450,000) ÷ 5 ≈ **AED 97,100 per year**. That is the threshold to compare with the real amounts in your quote.

Run the same calculation with **15 users**: the subscriptions fall to about AED 298,400, or AED 438,400 with set-up and connectors. That is less than the build alone: here, SaaS wins.

What the calculation does not show:

-   **Re-keying.** Cost it at the fully loaded hourly rate: in our assumption, 10 hours a week at AED 150 an hour over 47 weeks comes to about AED 70,500 a year, or more than AED 350,000 over 5 years. Do not assume custom software removes all of it; measure it during the assessment.
-   **After five years.** The subscription goes on; owned software stays yours, with only its running costs.
-   **Your team’s time.** A custom project needs an in-house lead and regular approvals. It is a real cost, and a condition of success.
-   **The accounting treatment.** Whether the build is an expense or an asset is decided with your accountant. See [rent or own your business software](https://c-esium.com/en/guides/rent-or-own-your-business-software/).

## Firm quote or price range: what difference does it make?

A range (“between AED 300,000 and AED 550,000”) leaves the uncertainty on your side. A firm quote commits the provider to a price for a written scope.

At C-Esium, the firm quote is delivered at the end of scoping, with the map of your current process, the friction quantified in time, the target scope, the integrations and a phased roadmap. It is possible because the assessment follows the real journey of a case, from the first call to the invoice.

A firm quote does not freeze your project: any request outside the written scope is simply quoted separately, before work starts. Be wary of a firm price given without scoping: either the scope is vague, or the safety margin is in the price.

## How do you read a quote for custom software?

Before signing, check that the quote answers these questions:

1.  **Scope**: is it described in processes and screens, not only in development days?
2.  **Integrations**: are they listed one by one, with the direction of each data flow?
3.  **Data migration**: is it included and priced?
4.  **Payment milestones**: do they match deliverables you can see and approve?
5.  **Acceptance**: who approves each batch, and against which criteria?
6.  **Ownership**: is the assignment of rights to the project code, the data and the documentation written into the contract?
7.  **Recurring costs**: are hosting, maintenance and further developments priced, or at least described?
8.  **Training**: are training and support for your teams planned?
9.  **Exclusions**: is what is not included written down in black and white?

## When is custom software not the right option?

Custom software is not always the right answer. Choose off-the-shelf software instead if:

-   your processes are standard and a SaaS for your sector already covers them;
-   your budget is below AED 40,000 (€10,000 in France); if it is below AED 200,000 and you want the whole company covered, start instead with a focused project on the process that costs you the most time;
-   your team is small and the 5-year calculation favours SaaS, as in the 15-user example;
-   nobody in-house can lead the project: without an internal lead, a tool, however good, is not adopted.

## Frequently asked questions

### What is the minimum budget for custom business software with C-Esium?

A complete internal software from C-Esium starts from AED 200,000 excluding VAT (€50,000 for clients in France): a company of about fifteen people can, from AED 200,000, bring its key operations together in a single tool. To start smaller, a focused project starts from AED 40,000 (€10,000 in France). The final amount is set in a firm quote after the assessment.

### Does the price depend on the number of users?

Yes, but not as a licence: C-Esium charges no per-user licence. The number of people who use the software every day affects the roles and permissions to design, the training, the support for your teams and the reliability required.

### How is a custom software project paid for?

At C-Esium, payment is spread over the project milestones: kick-off, mock-ups, screen approval, delivery. A V1 on a focused scope is delivered in 1 to 2 months, and maintenance is optional, as a monthly package.

### Is custom software cheaper than a SaaS subscription over 5 years?

It depends mainly on the number of users, the cost of setting up the SaaS and the time lost re-keying data. With many users and specific processes, custom software can become competitive over 5 years; with a small team and standard processes, SaaS is usually cheaper. Run the calculation with your own figures.
