How Much Does a Custom ERP Cost? Real Prices, Cost Drivers and a 3-Year View

Ask ten software companies what an ERP costs and you'll hear numbers from a few thousand dollars to several hundred thousand. They're not all wrong: "ERP" can mean a stock-and-invoicing system for one shop or a system that runs manufacturing, payroll and accounting for a group of companies.

This guide shows what actually drives the price, gives our real starting prices, explains the running costs people forget, and shows how to compare a custom system with a ready-made ERP subscription over three years. If you haven't yet decided between building and buying, start with our custom ERP development overview.

The short answer: our prices

These are Q Studio's starting prices in USD. Each project gets a written scope and a fixed price before any payment, paid in milestones (usually 30% / 40% / 30%) after you see each stage working.

"Starts at" means the price for a clear, moderate version of that scope. The rest of this article explains what pushes a project above it.

What drives the cost of an ERP

1. Number of modules, and how they connect

Each module (sales, inventory, purchasing, POS, HR, accounting, projects) adds screens, rules and reports. The connections cost as much as the modules: when a POS sale must reduce stock, post revenue and update a customer balance, every step has to stay correct when something is cancelled, returned or edited.

2. Roles, permissions and approvals

Two roles (admin and staff) is simple. Six roles, branch-level visibility, discount limits per role and three-step purchase approvals is a lot more logic and a lot more testing. It's also the part you most regret getting wrong, so it's worth paying for.

3. Integrations

Every external system is its own small project: an e-invoicing platform, a payment gateway, your online store, WhatsApp Business Platform, a bank file format, or an accounting system you're keeping. Price depends on whether the other side has a good API, and on how much you need to move in each direction.

4. E-invoicing

If your system issues tax invoices in Saudi Arabia (ZATCA) or Egypt (the Tax Authority's e-invoice and e-receipt systems), compliance is a defined part of the scope. Connecting through a certified e-invoicing provider's API is usually faster and cheaper to build than integrating directly with the tax platform, but adds a provider fee. See ERP development in Saudi Arabia and in Egypt.

5. Data migration

Moving 300 clean items from one spreadsheet takes hours. Moving 8,000 items with three names each, customers duplicated across branches, and opening balances nobody trusts takes days of cleaning and checking. We look at a sample of your data before quoting so this is priced, not guessed.

6. Branches and warehouses

Multiple locations add transfers between them, stock per location, branch-level reports and permissions. It's a common requirement and a real cost driver.

7. Offline POS

A cashier screen that works only online is a normal web app. One that keeps selling when the internet drops, then syncs without double-counting stock, is a harder design. Decide early whether your shops actually need it. More on this in POS system development.

8. Reports

A dashboard and a handful of standard reports (sales by branch, stock levels, overdue invoices) are quick. Dozens of custom financial reports, each with its own filters and exports, add up.

A phased plan: how full ERPs get built and paid for

We don't quote a full ERP as one large fixed number, because nobody can scope every module accurately on day one. Instead:

1. Phase 1: the module that hurts most, often inventory or sales and invoicing. Priced on our tiers (from $1,500 for one focused module).
2. Phase 2: the modules that connect to it, such as purchasing and POS. Quoted once Phase 1 is live and you know what you actually need.
3. Later phases: HR and payroll, projects, manufacturing, portals, mobile apps for field staff.

Each phase has its own written scope and fixed price. You can stop after any phase and still own a working system, and the code, database and accounts are in your name from day one.

Running costs people forget

The build is one cost. Running the system is another, smaller one that continues:

Because everything is in your name, there's no license fee to us for using your own system.

Comparing with a ready-made ERP subscription

Ready-made ERPs (Odoo, Zoho, SAP Business One and others) usually charge per user per month, often with higher plans for advanced features, plus implementation or customization fees if a partner sets it up for you. Prices change, so check each vendor's current pricing page rather than any figure in an article, including this one. Odoo, for example, lists its plans per user per month and ties some features, such as external API access, to specific plans.

A subscription isn't "worse": it includes updates, hosting and a product many companies already use. The point is to compare like with like.

A 3-year way of thinking

Put both options in one table for three years:

Run it with your real headcount, including the drivers, cashiers, technicians and branch staff who need only light access. For a small office team with standard processes, the subscription is often the cheaper route. For dozens of users who each need only one or two screens, the result can change, so do the sum rather than assume. Our custom ERP vs Odoo guide goes through the non-financial side too.

How to cut the cost without cutting corners

• Start with one module. Get it live and used, then decide what's next with real experience.
• Keep what works. If your accounting software is fine, keep it and integrate with it instead of rebuilding accounting.
• Clean your data before migration. An afternoon merging duplicate items saves paid days later.
• Use standard reports first. Add custom reports once people use the system and know what they're missing.
• Skip offline mode unless you really need it.
• Write clear requirements. How to write app requirements shows how; clearer scope means a tighter quote.
• Test a clickable prototype ($500) if you're unsure, before committing to the build.

FAQ

Why do ERP quotes vary so much between companies?

Different scopes, team sizes and overheads. One quote may include a single module, another a full suite with on-site consultants and training. Ask each company for a written list of modules, roles, integrations and data migration included, then compare those, not the totals.

Can I get a fixed price for a full ERP?

Per phase, yes. We give a fixed price for each phase based on a written scope. A single fixed price for every module up front usually means the quote either padded the unknowns or will grow later.

Is e-invoicing included in the price?

Only if it's in the scope. If your system issues tax invoices in Saudi Arabia or Egypt, we include it from the start and state whether we connect directly or through a provider, since that changes both build and running costs.

What happens to the cost if we add users later?

On your own system, extra users mainly add a little hosting load. With a per-user subscription, each new user adds to the monthly bill. That difference grows as you hire.

Do we pay a yearly license to Q Studio?

No. You own the code and accounts. You pay the hosting and service providers directly, and pay us only for work you ask for after the included bug-fix window.

How long until we see something working?

A first working preview within 72 hours of starting, then milestones every few days. One focused module is typically live in about 3 weeks.
