Data Integrity Policy

CRITICAL: Do not tamper with the date and time settings of your computer while using Calcuin. Our mathematical verification engine uses system timestamps to maintain ledger consistency. Manually changing your system clock can lead to severe data corruption in your saved invoices and miscalculations in the CRM Ledger.

Troubleshooting: Data Import

If your old CSV files aren't importing correctly, ensure they are formatted with standard UTF-8 encoding. Our bulk-processor requires specific column headers as defined in the Advance Biller module.
