Custom ERP software that runs your operations in one place
Rinaztec builds custom ERP software for small and mid-sized businesses that are running operations across spreadsheets and disconnected tools. We build it in phases, starting with the module that hurts most, such as inventory, orders, production or job tracking, so you see value in weeks rather than waiting a year. A first ERP module starts from $15,000 and takes 6 to 10 weeks.

What is a custom ERP?
An ERP (enterprise resource planning) system connects the core parts of a business, such as sales, inventory, purchasing, production, jobs and finance, into one source of truth. A custom ERP is built around your own processes instead of forcing your team into a large generic platform, and it can be delivered one module at a time.
ERP modules we build
Inventory and stock control
Real-time stock levels, locations, reorder points and supplier purchasing.
Orders, quotes and invoicing
From quote to order to invoice without re-typing data, connected to your accounting software.
Production and job tracking
Track jobs through each stage of your workshop or production line and show customers their progress.
Scheduling and resources
Plan people, machines and vehicles and see capacity at a glance.
Reporting and dashboards
Margins, throughput and cash flow from live data rather than month-end spreadsheets.

How much does custom ERP development cost?
Custom ERP is best built in phases. A first module starts from $15,000 and takes 6 to 10 weeks; later modules are quoted individually. This keeps risk low, spreads the cost, and means you get a return from the first phase before committing to the next.

Custom ERP Development questions, answered
Is custom ERP only for large companies?
No. Phased custom ERP suits small and mid-sized businesses well, because you only build the modules you need, in the order you need them.
Should we choose custom ERP or an off-the-shelf system?
Off-the-shelf ERP works when your processes are standard. Custom ERP is worth it when your operations are your competitive edge, or when a generic system needs so much customisation that you end up paying for both.
Can a custom ERP connect to Xero, QuickBooks or Shopify?
Yes. We integrate with accounting, e-commerce, shipping and payment platforms through their APIs.
How long does a custom ERP take?
The first module usually goes live in 6 to 10 weeks. A full ERP is built over several phases.
