Accounts and GST

The books are done when the invoice is.

Every invoice, bill, payment, receipt and expense in SDU One posts its own voucher. GST returns are built from the same documents, so what you file matches what you billed.

Books

Double entry, without the data entry.

A ready chart of accounts, grouped the way Tally groups it. Sales, purchases, receipts, payments and payroll post themselves; you add expenses, contra entries and journals by hand when you need to.

Vouchers are never edited - a mistake is reversed, so the trail stays clean
Opening balances on the day you start
Lock the books up to a date once the month is closed

SDU One journals: receipts, sales and purchase vouchers with number, date, narration, reference, amount and status

Bank

Bank reconciliation in minutes.

Import the bank statement as a file. SDU One matches lines to vouchers by amount and date, and leaves you only the ones it could not place - usually a bank charge or interest to record.

Balance per books, per statement and the difference explained
Match, unmatch and record what is missing
Duplicate lines skipped on re-import

SDU One bank reconciliation: balance per books, balance per statement, unmatched statement lines and vouchers not yet on the statement

GST

GSTR-1 and GSTR-3B from what you billed.

Every month shows its invoices, outward tax, input credit and due dates. GSTR-1 is grouped into B2B, B2C, credit notes, HSN summary and documents issued; GSTR-3B sets off the credit for you. Mark a month filed with its reference and it stays locked.

GSTR-1 as portal JSON or Excel
GSTR-2B imported and matched against your bills
E-invoice details ready for the portal, IRN recorded on the invoice
Reverse charge handled

SDU One GST returns by month: invoices, outward taxable value, output tax, bills, input credit, GSTR-1 and GSTR-3B due dates and filing status
