Software Development: frequently asked questions
What is ERP software and does my business need it?
+
ERP (Enterprise Resource Planning) software connects departments such as inventory, purchase, sales, accounts and HR in one system, so everyone works from the same data. If your team relies on several spreadsheets, separate tools or manual registers to run daily operations, a custom ERP usually saves time and reduces errors.
What is the difference between ERP and CRM software?
+
ERP software manages internal operations such as stock, purchase, accounts and HR. CRM software manages customers and sales: leads, follow-ups, quotations and support. Many businesses start with one and add the other later; we can build both as one connected system.
Why choose custom ERP or CRM software instead of a ready-made product?
+
Ready-made products force you to change your process to fit the software and often charge per user every month. Custom software follows your exact workflow, includes only the features you need, and you own the source code once the project is settled.
Can you migrate data from Excel or our existing software?
+
Yes. We import customers, products, stock, ledgers and other records from Excel, CSV or your existing system during setup, and verify the data with your team before going live.
Will the software work on mobile phones?
+
Yes. All our software is responsive and works in the browser on desktop, tablet and mobile. Where field staff need offline access, GPS or camera features, we also build a companion Android and iOS app.
How long does it take to build custom software?
+
It depends on the number of modules and integrations. A focused system is typically delivered in a few weeks, while a multi-module ERP is planned in milestones. You receive a timeline with the written scope before the project starts.
Is our business data secure?
+
Yes. Systems use role-based access, encrypted passwords, activity logs and regular backups, and are hosted on secure servers. Your data and source code belong to you.
Do you provide support after the software goes live?
+
Every project includes a one-month warranty for bug fixes. After that, you can choose a maintenance plan covering monitoring, backups, security updates and small changes.
