Customer-Centric Sales Management System

I’m building a focused sales management tool whose single priority is strengthening customer relationships. The heart of the platform will be a clean, searchable record of every customer’s purchase history, organised by product so I can instantly see who bought what, how often, and when.

Here’s what I need from you:

• A straightforward interface to add, edit and view customers.
• A robust backend—SQL, Firebase, or another scalable store—that lets me attach multiple product purchases to a single customer profile.
• Smart filters and a quick search so I can pull up “all customers who purchased Product X” in seconds.
• Import / export options (CSV or similar) for bulk data moves and offline analysis.
• Clear, well-commented code and a brief README so future tweaks are easy.

No extra reporting modules or complex forecasting dashboards—just a reliable CRM core that keeps purchase history front and centre, indexed by product. If that sounds like your sort of build, let’s talk details and timelines.
