Short answer: In 2026, an ERP system custom-built for your business typically costs between €900 and €9,000, depending on its scope. The three biggest cost drivers are the number of modules you need, the integrations with your existing software and the licensing model you choose (perpetual licence with source code, or a monthly subscription).
In this article, we explain why that range is so wide, how each module affects the price and what to watch out for when you request a quote. If you haven't yet worked out what ERP is and when your business needs one, start with our article What Is ERP Software?
ERP software price ranges
| Scope | Best for | What's included | Price range |
|---|---|---|---|
| Mini ERP | Small businesses that want to move away from Excel and paper slips | 2-3 core modules (e.g. inventory, purchasing, basic reporting), user permissions, admin panel | €900 – €2,200 |
| Standard ERP | SMEs that want to bring several departments into one system | Inventory, purchasing, sales, finance, task management, department-based permissions, reporting | €2,200 – €4,500 |
| Comprehensive ERP | Businesses with multiple branches or warehouses, or with production | Everything in Standard, plus production, multiple warehouses and branches, accounting and e-invoicing integrations, B2B or e-commerce connections, custom workflows | €4,500 – €9,000 |
These are one-time development costs. We cover ongoing costs such as hosting, maintenance and support separately below.
5 factors that determine the price
1. Number and scope of modules
What drives the cost of an ERP the most is which business processes move into the system. The most requested modules:
- Inventory: product records, stock-in and stock-out slips, stock counts, waste and loss, low-stock alerts
- Purchasing: suppliers, purchase requests and purchase orders
- Sales: quotes, orders and customer management
- Finance: income and expenses, customer and supplier accounts, collections and payments
- Operations and task management: tracking work across departments
- Production: bills of materials, work orders, production planning
- Reporting: summary dashboards and detailed reports for managers
Each module can look simple on its own. The real work is connecting them: making sure a purchase order is reflected correctly in inventory, and a sale correctly in finance.
2. Integrations
An ERP is rarely the only software in a company. What adds value is its ability to talk to other systems:
- Accounting software such as Logo, Mikro or Netsis, or any other system with an API
- E-invoicing providers
- E-commerce sites and marketplaces
- B2B dealer portals
- Payment and shipping services
Each integration brings a different workload depending on what the other side offers. We explain how integrations work in detail in What Is ERP Integration?
3. Users and permissions
A system used by a single manager doesn't cost the same as one where the kitchen, warehouse, sales and accounting teams each see their own screens. Department and role-based permissions make sure every user only sees the screens relevant to their work, but they require additional development.
4. Licensing model: perpetual licence or monthly subscription?
| Perpetual licence + source code | Monthly subscription | |
|---|---|---|
| Upfront cost | Higher | Lower |
| Source code | Yours | Stays with the provider |
| Freedom to change the system | Full | Changes go through the provider |
| Updates | Depend on the maintenance agreement | Usually included in the monthly fee |
| Best for | Companies that see their ERP as a long-term business asset | Companies that want to start quickly with a low upfront cost |
An ERP is a system a business uses for years. That's why a perpetual licence usually works out better in the long run.
5. Data migration
If your product lists, customer and supplier accounts and stock data live in Excel or an old program, they need to be moved cleanly into the new system. How well organised that data is directly affects how long this takes and how much it costs.
Off-the-shelf or custom ERP?
There are off-the-shelf ERP packages available for a licence fee or a monthly subscription. For many businesses with standard accounting and inventory needs, a ready-made package can be a sensible place to start.
A custom ERP is usually the better choice when:
- The way your business works doesn't fit the mould of off-the-shelf packages
- You wouldn't use most of a package's modules, yet it still can't cover a few of your specific needs
- Per-user licence fees turn into a significant cost as your headcount grows
- You want to develop the system further around your own needs in the future
You'll find the full comparison in our article Off-the-Shelf ERP vs Custom ERP.
Ongoing costs
The development fee is a one-time cost. But keeping the system running involves some ongoing costs:
- Hosting: We host our projects on EG678 Cloud infrastructure.
- Maintenance and support: security updates, backups, bug fixes and technical support
- Third-party fees: for services such as e-invoicing providers, which charge their own fees
When you request a quote, always ask whether these items are included.
How long does an ERP project take?
Timelines depend on scope: a mini ERP usually takes 4-6 weeks, a standard ERP 2-3 months and a comprehensive ERP 3-6 months.
The process usually goes like this:
- Analysis: Each department's processes, the modules needed and the integrations are defined.
- Design: The screens each department will use are designed.
- Development and integrations: The modules are built and connections to other systems are set up.
- Data migration and testing: Existing data is imported and the system is tested with real users.
- Training and go-live: The team gets used to the system, and the old way of working is retired.
The most time-consuming stage of an ERP project is usually the analysis. The better the analysis, the faster and smoother development goes.
A real example: a mini ERP for a hotel
The mini ERP we built for a hotel in Şile, Istanbul, which also runs a restaurant and a bar, is a good example of a system designed around actual needs. In this system:
- Kitchen, bar and reception stock is tracked separately for each department.
- Stock-in and stock-out slips, stock counts and loss records are all handled in the system.
- Purchasing, suppliers and income and expenses are managed from a single panel.
- Tasks are assigned and tracked across departments.
- Each user only sees the screens for their own department.
As a result, information that used to be scattered across Excel files is now in one system. For details, see our hotel mini ERP project page.
7 questions to ask when requesting a quote
- Which modules are included in the price? How much does it cost to add a module later?
- Which integrations are included? Can the system integrate with the accounting software I use?
- Is it a perpetual licence or a monthly subscription? Will I own the source code?
- Is migrating my existing data included in the price?
- What will I pay each month for hosting, maintenance and support?
- Are there extra charges as the number of users grows?
- Will my team be trained, and how many months of free support are included after delivery?
Frequently asked questions
How much does ERP software cost?
An ERP system custom-built for your business typically costs between €900 and €9,000 in 2026, depending on its scope. The number of modules, integrations and the licensing model are the main cost drivers.
What is a mini ERP?
A mini ERP is a leaner system that includes only the few core modules a business actually needs (e.g. inventory, purchasing, finance), rather than every module of a large ERP package. For small businesses, it's quicker to set up and more affordable.
Can I use an ERP with my existing accounting software?
Yes. Most accounting software supports integration. You can keep using your current program while we set up the ERP to work alongside it.
Will I get the source code?
With the perpetual licence model, we deliver the system together with its source code.
Should I buy an off-the-shelf ERP or have a custom one built?
If your processes are standard, an off-the-shelf package may be enough. If the way you work is specific, if you need to connect several systems, or if per-user licence fees keep rising, a custom ERP makes more sense.
Do you work with companies in Kosovo and Europe?
Yes. Through our Kosovo company, EG Software LLC in Pristina, we sign contracts and invoice in euros. See our Kosovo page.
Conclusion
ERP software prices vary widely because every business has different processes, departments and software. To get an accurate quote, first decide which processes you want to move into the system, then compare modules, integrations, licensing models and monthly costs.
