Custom ERP development, with a build-or-buy test first

- Custom ERP
A custom ERP makes sense when the process that earns the money fits no package and the business will outgrow spreadsheets within a year. We say so when a package or ZMOS is the better answer; when custom is right, we build it in stages you can run from the first one.
- Build-or-buy decision in the first call
- Written scope, timeline and cost before work starts
- Code, data and documentation in your name
- One month of free support after launch
When custom is worth it
Custom pays off when the process is close to the cash register and no package fits it.
- Your order-to-cash or quote-to-job flow has rules a package cannot express
- Two or more systems must stay in sync and nobody owns the join
- A legacy tool runs a key process and cannot be maintained
- You need a customer or partner portal on your own data
If stock, BOMs, jobs and cost are the problem, ZMOS may already be the answer at a fraction of the cost; we will tell you.
What drives the cost
- Modules
Each area (sales, stock, production, finance) is scoped as its own stage with its own screens and rules.
- Integrations
Accounting, e-commerce, payments, courier and banking APIs; each adds design, error handling and testing.
- Data migration
Clean lists shorten everything; messy history is the commonest overrun.
- Roles and approvals
Every role and approval path is a screen and a rule to test.
- Reporting
Dashboards per role, and the exports your accountant needs.
How an ERP build runs
Stages ship working software; you run stage one while stage two is built.
- Discovery
The process as it is, the people, the numbers that matter.
- Scope
Modules, screens, rules, integrations and data, written down with a price.
- Build in stages
Demos every stage; the first stage goes live early.
- Migrate and train
Data imported and checked; users trained on their own screens.
- Support
One free month, then optional monthly support.
Our stack, and why
Node.js, PostgreSQL and a web front end for custom builds; Zoho Creator when a low-code app is enough; ZMOS when the shape is a manufacturing shop.
- Hosted where you choose; code in your repository
- Documentation and handover included
- The estimator on the pricing page gives typical hours
Questions
How much does a custom ERP cost?
It depends on modules, integrations and data. We quote a fixed price per stage after a discovery call; the estimator on our pricing page shows typical hours for custom software. Custom builds start from the hundreds of hours.
Should we buy an ERP instead?
Often yes. If a package or ZMOS covers 80 % of the process and the remaining 20 % can live in a custom add-on, that is cheaper and faster. We say so in the first call.
Tell us the workflow that breaks
We reply within 6 hours with questions or times for a call, then a written proposal with scope, timeline and cost.
