FAQ
What happens if I need to add more pages or fields after development starts?
Any additional pages, database modules, or interface layouts outside of our initial project scope discussion will be billed as an extra gig add-on. Please ensure all your data fields are finalized during our onboarding chat.
Can I connect multiple barcode scanners or different printer models later?
Each package includes integration for exactly one specific barcode scanner and one printer model. If you use different models across multiple branches or need specialized hardware syncs like digital scales, it will require an additional custom charge.
Who pays for the SMS, WhatsApp, or Payment Gateway API fees?
The client is entirely responsible for setting up and paying for all third-party subscription costs (such as Twilio, Stripe transaction fees, or WhatsApp Business API accounts). I only handle the secure code integration into your web application.
Do I need to be accountant / from accounting background to use and maintain this system?
Not at all. While the system runs a professional double-entry engine with a Chart of Accounts (COA), the interface is designed for non-accountants. It uses a guided workflow that automates the complex math, so you can manage your own books accurately without hiring a professional.
Can this custom business management software run completely offline?
Yes, absolutely! Because this is a lightweight, raw PHP and MySQL web application, it can be deployed directly on a local server or office LAN environment. It functions smoothly offline, keeping your operational data private and secure.
What do you need from me to start building my custom CRM/ERP software?
Please share your exact operational workflow, an outline of the modules you need (like stock or purchases), and any current data formatting rules. I will then map the custom relational MySQL schemas and functional PHP logic to fit your business.
Do you use frameworks like Laravel or WordPress for development?
No. I build your custom CRM or business tool from scratch using pure, functional PHP and MySQL. This zero-dependency approach ensures your web application experiences zero bloat, runs at blazing-fast execution speeds, and remains ultra-portable.
How do you ensure data security in my custom web application?
Security is embedded at the code level. I implement strict session management, Admin role constraints, device lock restrictions, and secure inputs to protect your custom PHP and MySQL database structures from internal leaks or malicious exploits.
