FAQ
What's the difference between a CRM and an ERP — which do I need?
A CRM (Customer Relationship Management) is focused on your sales and customer side: leads, deals, client communication, and revenue tracking. An ERP (Enterprise Resource Planning) covers the operational side: inventory, procurement, HR, payroll, and finance. Most growing businesses need both — and
Can you migrate my existing data from spreadsheets or another system?
Yes. If you have structured data in Excel, Google Sheets, or another platform, I can import it into the new system as part of the project. Send me a sample of your current data format when you message me and I'll confirm how cleanly it maps across.
How do user roles and permissions work?
I implement role-based access control (RBAC) from the start. Common roles are Admin (full access), Manager (can view and edit, can't delete or configure), and Staff (can view and add, can't edit others' records). I'll build your specific roles based on how your team is structured — these aren't fixe
Can the ERP/CRM handle multiple locations or branches?
Yes. Multi-location support (separate inventory per branch, consolidated group reporting, branch-level user accounts) is available in the Premium package or as an add-on. This is common for retail chains, franchise businesses, and companies with warehouses in multiple cities.
Will the reports export to PDF and Excel?
Yes, standard in all packages. Common exports include inventory reports, sales reports, invoice PDFs (ready to send to clients), employee attendance summaries, and purchase order documents. If you need a specific report format, tell me during scoping.
Can you add more features after delivery?
Yes — most ERP clients come back for phase 2 features after launch. I offer post-delivery feature additions at a per-feature or monthly retainer rate. Because you own the codebase and I wrote it cleanly, adding features is fast and straightforward. No rework required.
How long does a full ERP take to build?
The Premium package (Full ERP Suite) has a 25-day delivery window. For larger, more complex systems — multi-company, advanced payroll, complex reporting — I'll quote a custom timeline. The key is a clear scope before we start: a well-scoped ERP builds faster than a vague one that changes mid-project
