Purchase Invoice
Recording purchase bills and booking input tax credit.
Purchase Entry
Go to Vouchers → Purchase. The entry is identical to a Sales Invoice with roles reversed: the party is your supplier, stock increases, and input GST (CGST+SGST or IGST) is booked to your Input Tax Credit ledgers.
Enter the supplier's invoice number in the Reference Number field. This is used in GST reports to cross-check with GSTR-2A.
Input Tax Credit Ledgers
AccountManager posts GST automatically to ledgers named Input CGST, Input SGST and Input IGST — these ledgers sit under Current Assets → Duties & Taxes. At the end of the month, offset them against your Output GST ledgers when filing returns.
