NOTE
Workflow Demonstration & Illustrative Case Study: This article demonstrates how bookkeepers can select basic vs. full GST invoice fields in AccuRaik. The scenarios and values below are examples; no measured product accuracy or time savings are claimed.

📋 Case Study Snapshot

Persona Independent Bookkeepers & Accounting Practitioners
The Challenge Some bookkeeping tasks need only basic invoice totals, while GST filing requires complete party GSTINs, taxable value, and tax splits. A single fixed template adds review bloat.
Solution Approach Use AccuRaik's Choose Individual Fields interface to toggle between a 4-field minimal set and an extensive 19-field GST-oriented profile.
Demonstrated Outcome Two clearly scoped extraction configurations with focused review and dependable TallyPrime handoff.

Why One Invoice Template Does Not Fit Every Bookkeeping Task

A bookkeeper might prepare a simple expense summary for a small business, then process tax invoices for a GST-registered client. The first task may only require the invoice number, date, party and total amount. The second may require seller and buyer GSTIN, place of supply, taxable value, CGST, SGST, IGST, cess and other adjustments.

Capturing every possible field for every invoice can clutter the output; capturing too few can force rework.

AccuRaik lets users search and choose individual fields grouped under Invoice, Party, Amounts & Tax, More Details, Status, Seller Bank Details and Item Details. That makes the extraction request adaptable to the purpose of the accounting task. The tool still requires users to check that extracted values match the source invoice.


Scenario A 4 Core Fields

Basic Invoice Capture for Expense Register

Designed for quick invoice identification, petty cash logs, and basic expense tallying without complex tax calculations.

Selected Fields:
Invoice No Invoice Date Party Name Total Amount
Illustrative Output (Example):
Invoice No: SOS-1042
Invoice Date: 2026-10-12
Party Name: Sunrise Office Supplies
Total Amount: ₹5,900
Review Focus: Supplier identity, invoice number characters, duplicate candidate checks, and document authenticity.
Scenario B 19 Selected Fields

Full GST-Oriented Invoice Extraction

Designed for input tax credit (ITC) reconciliation, state-wise GST audits, and structured TallyPrime purchase voucher entry.

Selected Fields:
Invoice No Invoice Date Type Seller Name Seller GSTIN Buyer Name Buyer GSTIN Place of Supply Taxable Amount CGST SGST IGST Cess Total Tax Discount Freight Round Off Total Amount HSN / SAC
Illustrative Output (Example):
Invoice No: EBS-2026-078
Taxable Amount: ₹10,000
CGST: ₹900 | SGST: ₹900 | IGST: ₹0
Total Tax: ₹1,800
Total Amount: ₹11,800
Review Focus: Supplier vs Buyer GSTIN, tax split accuracy, arithmetic reconciliation, and ledger mapping.

Side-by-Side Comparison: What Changes?

The same source invoice can be processed under either configuration depending on your client’s operating requirements:

Criteria Basic Capture (Scenario A) Full GST Extraction (Scenario B)
Fields Selected 4 core fields 19 structured fields
Primary Objective Document registry, petty cash, initial receipt triage GST return reconciliation, ITC audit & Tally posting
Review Overhead Minimal (identity and gross amount only) Detailed (tax components, math reconciliation)
Accounting Readiness Requires tax ledger additions before voucher creation Ready for automated Tally XML voucher generation

End-to-End Workflow for Bookkeepers

Follow these seven practical steps to establish a dependable document pipeline:

  1. Define the downstream purpose: Decide whether the document is for a basic register, a GST-oriented purchase review, a sales review or voucher preparation. Do not choose fields solely because they are available; choose them because the next accounting step needs them.
  2. Choose the appropriate fields: Use the search box or field sections to select the basic or detailed configuration. For repeat clients, document the chosen fields in your operating procedure.
  3. Process representative documents: Test digital PDFs, scanned bills and phone images that are supported by your product version. Include supplier variations and invoices with tax splits, discounts or multiple pages.
  4. Review extracted data against the source: Inspect the selected fields side-by-side and correct OCR mistakes. For basic capture, focus on identity and total. For GST capture, also inspect GSTINs, tax types, rates, item details and the arithmetic of invoice totals.
  5. Apply accounting controls: Check duplicate invoice candidates, party identity and ledger classification. If preparing vouchers, verify debit/credit treatment and the selected tax ledgers. A correct extraction is only one step toward a correct accounting entry.
  6. Export or prepare for Tally: Use the export or Tally-oriented process supported by the current AccuRaik version. Confirm the file structure, ledger mapping and target company. If a connector is used, verify the posted voucher in TallyPrime rather than relying on a transfer notification.
  7. Track review status: Where relevant, include Review Status, In Tally and Source File among the selected fields to support traceability. These fields help document the workflow; the actual accounting system remains the source of truth for posted records.

What Can Go Wrong? (6 Pitfalls to Avoid)

1. Wrong party identified A document can display seller, buyer, ship-to and bill-to names. Verify the extracted role before mapping the ledger.
2. GSTIN characters misread OCR may confuse O/0 or I/1. Format checks flag syntax but do not prove an active GST registration.
3. CGST/SGST confused with IGST Preserve the tax labels shown on source bills and review place-of-supply context before posting vouchers.
4. Discount or freight omitted If these adjustments affect the gross total, include them in selected fields to prevent math discrepancies.
5. Multi-line tax groups flattened If an invoice contains items at different GST rates, select item fields and test if line-item tax relationships are preserved.
6. Basic output treated as full voucher A 4-field record lacks the tax context needed for final ledger postings. Never post without complete accounting classification.

How to Measure a Real Pilot

Run a controlled test with two groups of comparable invoices: one using the minimal selection and one using the detailed GST selection. Record the exact fields selected, invoice types, document quality, extraction corrections and time required for accountant approval.

Suggested Pilot Metrics to Capture:

  • Field accuracy: Exact matches divided by checked fields, reported separately for invoice number, date, GSTIN, tax components and totals.
  • Completion rate: Proportion of documents with all required selected fields captured or explicitly marked unavailable.
  • Review time: Minutes spent checking and correcting each invoice.
  • Exception rate: Percentage of invoices requiring manual intervention, with reasons.
  • Posting verification: Approved voucher count versus records actually present and correct in TallyPrime.
  • Configuration effort: Time needed to change selected fields between the two workflows.

Why This Matters for Accounting Practices

Selective extraction helps bookkeepers align the output with the task: a compact register for one client and detailed tax fields for another. It can make review requirements clearer and prevent irrelevant fields from dominating the workflow. It does not replace reconciliation, accounting classification, GST interpretation or human approval.
