Custom Web Application vs Excel Spreadsheets: When Should Your SME Upgrade?
Direct Answer Summary
Upgrade to a custom web application as soon as your Excel spreadsheets slow down, cause input errors, lack role-based access control, or fail to support real-time multi-user collaboration.

Excel is great for starting out, but as your company grows, spreadsheet limits quickly turn into operational bottlenecks.
1. Bottlenecks of shared spreadsheets
Formula corruption, data loss, and zero access logging.
2. Benefits of a custom web application
Centralized PostgreSQL database with Row Level Security, instant multi-device access, and automated workflow triggers.
