How to Convert GST Invoices into Tally – Manual vs Automation

Manual GST invoice entry into Tally Prime is one of the most time-consuming tasks for Indian accountants. A typical CA firm processing 500 invoices per month spends approximately 40-50 hours on data entry alone.

The Manual Process

Traditionally, accountants follow these steps: open each PDF invoice, read party name, GST number, item details, tax amounts, then manually create purchase/sales vouchers in Tally. For a single invoice with 5 items, this takes 3-5 minutes.

The AI Automation Advantage

With LekhaFlow, you simply upload the PDF batch. The AI reads all invoices simultaneously, extracts GST numbers, item-wise bifurcation, and tax amounts, then generates ready-to-import Tally XML. What took 3 hours now takes 3 minutes.

Cost Comparison

At ₹15,000/month staff cost, manual entry costs ₹3.75 per invoice. LekhaFlow brings this down to under ₹0.10 per invoice at scale — a 97% cost reduction.
