Architecture Takeaway:

Generic SaaS ERP giants (SAP, Oracle NetSuite) force fast-growing companies into rigid workflows, exorbitant per-user seat taxes, and endless paid consulting hours. Our custom modular ERP architecture utilizes index-tuned relational schemas, role-based access control (RBAC), and automated event queues to mirror your exact manufacturing, warehouse, and accounting processes without recurring licensing penalties.

COMMON QUESTIONS

FAQ

Everything you need to know about custom ERP engineering.

What modules does a custom ERP system typically include?

Common ERP modules include: multi-warehouse inventory management, purchase orders, HR attendance & payroll calculation, multi-currency invoicing, P&L reporting, and sales CRM pipelines. We build only the modules your business actually operates with.

How long does it take to engineer and deploy a custom ERP?

A core 2–3 module ERP takes 8–14 weeks. Full enterprise-grade systems with 6+ modules take 16–24 weeks. We deliver in 2-week agile sprints, allowing your staff to use completed modules while others are being coded.

How do you handle data migration from our existing Excel sheets or legacy ERP?

We build automated ETL migration scripts that extract, clean, sanitize, and import all existing inventory catalogs, vendor details, customer accounts, and historical financial ledgers with zero data loss.

Where is the custom ERP hosted and is our business data secure?

Your ERP is deployed to your dedicated AWS or VPS server. All records reside in encrypted relational databases behind private subnets with automated daily off-site backups that only your leadership team controls.
