In plain words
What is it, and what does it do for my business?
No technical words: what it is, the problem it solves and how your day changes.
Custom ERP
- What it is
- ERP is one system to run the company: stock, purchases, orders, invoices and staff, connected to each other.
- Your problem today
- Each department uses its own spreadsheet and the numbers never match.
- Before
- You count stock by hand and invoices are done twice.
- After
- A sale updates the stock and the invoice at once, and you see the real numbers.
- Example
- A company with two warehouses: it knows exactly what is in each one before selling.

06Custom ERP: frequently asked questions
Before you run the company on one system.
Prices, delivery, ownership and support. If yours isn't here, ask us on WhatsApp: a person from our team replies.
Ask on WhatsApp (opens WhatsApp)Indicative prices from 8,000 to 80,000 USD, excluding taxes. The price depends on the number of modules, users, branches and integrations. We build in phases: the first one is 8,000–14,000 USD, and the largest projects are quoted after a discovery phase. Each phase has its own fixed scope and price, paid in three milestones: 40% when you sign, 40% when you approve the beta and 20% before launch.
One core module, usually the area that causes the most trouble today, such as stock or invoicing, with setup and training for your team. It takes 3–4 weeks from the signed scope. Each later phase adds modules to the same system.
We don't certify e-invoicing ourselves. Your ERP can connect to a certified e-invoicing or accounting provider for your country when that provider offers an API, so your official invoices are issued through them. We check this with you before you sign.
Ready-made ERPs work well when your processes fit them. Custom makes sense when your team keeps bending its work to the software, you pay for modules you don't use, or you need something they don't cover. If a ready-made ERP fits, we'll tell you on the call.
Yes. We can import your products, clients, suppliers and opening stock from spreadsheets, or from your current system if it can export the data. The migration is listed in the scope, so you know what moves and when.
You do: the code, your data, the domain and the accounts are in your name. We fix any bug free of charge for 90 days after launch. After that, maintenance is optional: from 99 USD/month (hosting, backups and security), or 249 USD/month with 4 hours of changes included.
