How AI Invoice Extraction and Tally XML Import Works
Manually re-keying vendor invoices into Tally is one of the largest sources of data-entry error in Indian accounting practice — mismatched GSTINs, wrong tax heads, and transposed amounts routinely cause GSTR-2B/purchase register mismatches later. This tool uses OCR and structured-data extraction to read PDF and scanned invoices and identify the fields Tally needs: supplier/buyer GSTIN, invoice number and date, line-item descriptions, HSN/SAC codes, taxable value, and the CGST/SGST/IGST tax split.
The extracted data is mapped to Tally's native XML voucher import format — the same schema Tally Prime uses for its Import Data feature — including the correct voucher type (Purchase or Sales), ledger names matched against your existing chart of accounts where possible, and GST classification consistent with Rule 46 requirements so the resulting voucher is filing-ready, not just bookkeeping-ready.
Because GST compliance depends on the invoice fields being captured correctly (see the GST Invoice Compliance Checker for Rule 46 validation), this tool cross-checks extracted invoices for missing mandatory fields — HSN code, GSTIN, place of supply — before generating the XML, so obviously defective source invoices are flagged rather than silently imported.
The output XML can be imported directly via Gateway of Tally → Import Data → Vouchers in Tally Prime, avoiding manual entry entirely for high-volume purchase and sales invoice processing. A direct API push to Tally (skipping the manual XML import step) is planned as a subsequent phase of this tool.
Worked Example: Batch Processing 50 Purchase Invoices
An accounting team receives 50 vendor PDF invoices for a month, previously requiring roughly 4 hours of manual Tally entry.
Frequently Asked Questions (FAQs)
Does this tool push data directly into Tally Prime automatically?
Currently it generates an XML file in Tally's standard voucher import format, which you import via Gateway of Tally → Import Data → Vouchers. Direct API-based push to Tally without the manual import step is planned as a future phase.
What invoice formats are supported?
Both digitally generated PDF invoices and scanned/photographed invoices are supported, using OCR for the latter. Extraction accuracy is generally higher for digital PDFs with selectable text than for low-resolution scans.
Does it validate GST compliance of the source invoice?
Yes — before generating the XML, the tool checks for mandatory Rule 46 fields (GSTIN, HSN code, place of supply, invoice serial number) and flags invoices with missing fields for manual review rather than silently producing an incomplete voucher.
How does it decide which Tally ledger to map an expense to?
It attempts to match extracted vendor names and item descriptions against your existing Tally chart of accounts (where supplied); unmatched items are mapped to a default suspense/review ledger so nothing is misclassified silently.
Can it handle both purchase and sales invoices?
Yes, the tool generates the correct voucher type — Purchase voucher for vendor bills and Sales voucher for outward invoices — based on whether your GSTIN appears as the buyer or the seller on the extracted invoice.
