Invoice renumbering

This discussion explores the process of renumbering invoices, receipts, and payments within TallyPrime, particularly for a Canadian client. The user successfully implemented a system for renumbering payments and receipts using acronyms (e.g., CAN1, CAN2). While sales invoices generally shouldn't be renumbered due to customer and legal requirements, purchases, receipts, and payments can be adjusted. The key lies in mastering Tally's 'Alter' function to input custom commands for renumbering.
