➔

2. Identify Debit & Credit Ledgers

➔

3. Input in TallyPrime

➔

4. Audit & Reconcile Reports

1. Verify authorization and underlying source document (invoice, challan, advice, or receipt).
2. Identify the applicable accounts or inventory items affected by the gst purchases, urd & reverse charge (rcm) transaction.
3. Apply appropriate accounting rules, tax slabs, or inventory valuation parameters.

5. Verify arithmetical balance, GST/TDS tax calculations, and bill-wise reference allocations.
6. Accept and save the entry; verify report reflections in Trial Balance, Stock Summary, or Day Book.

6. Accounting Logic & Journal Entry

Representative Transaction Double-Entry Standard

"Procured inventory goods worth ₹2,00,000 with 18% IGST from inter-state supplier in Delhi."

Identified Accounts: Purchases A/c | Input IGST A/c (Asset ITC) | Supplier Creditor A/c
Applied Rule: Debit purchases and eligible Input Tax Credit (ITC); Credit supplier liability.

Particulars	Debit (₹)	Credit (₹)
Purchases A/c	₹2,00,000
Input IGST A/c (18%)	₹36,000
To Supplier A/c		₹2,36,000

(Being inter-state purchase invoice recorded with full ITC entitlement.)

Why This Logic Works: The primary account is debited to recognize asset addition or operating expense; the bank account is credited to reflect the reduction in liquid funds.
