How much does custom ERP software cost? 2026 pricing guide

July 3, 2026

"How much will it cost me?" is the first question anyone considering custom management software asks — and the hardest one to find clear answers to online. This guide gives you concrete price ranges and the factors behind them, so you can approach a quote request well prepared.

The factors that drive the price

Two ERP systems can differ in cost by a factor of three. The difference almost always comes down to:

• Number of features: inventory, orders, invoicing, CRM, reporting — every module adds development days.
• Integrations: connecting the system to what you already use (accounting, e-commerce, couriers, suppliers) is the most underestimated item.
• Users and permissions: software for 3 people is simpler than software for 50 with roles and approvals.
• Data migration: importing years of history from Excel or a legacy system takes dedicated work.
• Where it runs: office only, cloud, mobile?

Indicative price ranges

Based on the projects we deliver, these are realistic starting points:

• Automation and integration of existing systems: from €1,500 — the cheapest entry point, often with the fastest payback.
• Custom ERP (inventory, orders, customers): from €2,500 for a first working module.
• Custom e-commerce integrated with suppliers and payments: from €3,500.
• Mobile app for iOS/Android: from €4,000.

A complete project with several modules and integrations can reach €10,000–30,000. The good news: you don't need to start with everything.

Custom or off-the-shelf?

Off-the-shelf software costs less upfront (€50–300/month subscriptions) but forces you to adapt your processes to the software, not the other way around. Custom pays off when your processes are a competitive advantage, when licence fees multiplied by users and years exceed the cost of development, or when packaged software simply doesn't do what you need.

How to keep costs down

• Start with an MVP: the module that solves today's most expensive problem. The rest comes in phases.
• Clear priorities: a "must have / nice to have / later" list written before the quote saves days of analysis.
• Reuse what works: if your accounting software is fine, we integrate it — we don't rewrite it.

Bottom line

The right price depends on your specific case, but be wary of quotes given without any analysis — and of anyone who can't at least give you a range. If you want a concrete number for your project, tell us what you need: the quote is free and without obligation.
