English Invoice Typing Service for GST Compliance

What a Standard Tax Invoice Contains

A GST-compliant tax invoice is more than just a bill. It serves as the primary document for claiming input tax credit (ITC) under Indian indirect tax rules. Every valid invoice must carry the supplier’s name, address, and GSTIN, as well as the recipient’s details if they are registered. A unique, consecutive invoice number, date of issue, and a clear description of goods or services, including quantity, unit, and taxable value, are mandatory. The document must break down tax into CGST, SGST/UTGST, or IGST depending on whether the supply is intra-state or inter-state. HSN codes for goods, the place of supply, and, where applicable, the e‑way bill number and transport details round out the prescribed format. Together these fields create a legal record that supports both commercial bookkeeping and GST audit trails.

Why Businesses Type Invoices for GST Compliance

Many businesses still receive paper purchase invoices, from local suppliers, transport vendors, or contractors, that never enter their digital accounts. For accurate input tax credit claims, every such invoice must be recorded with the supplier’s correct GSTIN, taxable value, and tax breakup. Typing these paper records into a structured digital format makes reconciliation with GSTR-2B easier and supports internal audit readiness. From our experience with business documents, companies also digitise paper invoices for centralised procurement records, vendor management, and backup copies before physical documents deteriorate. The typed record becomes searchable, editable, and shareable across departments, especially critical when the original is a single physical copy held at a branch office or warehouse.

AI-Powered Typing vs. E‑Invoice Generation: What Each Delivers

Lekhak’s AI typing converts a scanned paper invoice into a clean, editable DOCX file. The output faithfully types out every visible field, supplier and buyer GSTINs, line‑item descriptions, HSN codes, tax breakup, bank details, and transport particulars, preserving the structure of the original. This DOCX is not an e‑invoice for the Invoice Registration Portal (IRP). E‑invoice generation requires a machine‑readable JSON payload with a digital signature that only an IRP‑registered system can produce; it also mandates real‑time reporting to the GST Network. The typed DOCX is meant for your internal records, ITC reconciliation, audit files, and shared procurement workflows, not direct upload to the e‑invoice system. For businesses that still handle paper invoices from unregistered dealers or legacy suppliers, a good typed version is often the fastest way to get the data into their accounting software.

Key GST Invoice Fields You’ll Find Typed Out

The DOCX organises all fields into a straightforward table that mirrors the original invoice layout. Below are the most common fields we observe in documents we have processed, with placeholder tokens where specific identifiers appear in the actual output.

Field	Description	Example in Typed Output
Supplier GSTIN	GST Identification Number of the seller	[GSTIN]
Buyer GSTIN	GSTIN of the recipient (if registered)	[GSTIN] or "Unregistered"
Invoice Number	Unique serial number of the invoice	[INVOICE NO]
Invoice Date	Date of issue as printed on the document	[DATE OF ISSUE]
HSN Code	Harmonised System of Nomenclature code for goods	[HSN CODE]
Place of Supply	State or Union Territory where the supply is deemed to occur	[STATE]
IGST	Integrated GST amount for inter‑state supplies	[AMOUNT]
CGST / SGST	Central and State/UT GST amounts for intra‑state supplies	[AMOUNT]
Bank Details	Supplier’s bank account number and IFSC	[ACCOUNT NO], [IFSC]
Transport / E‑way Bill	Mode, vehicle number, and e‑way bill reference	[VEHICLE NO], [E-WAY BILL NO]

Line‑item rows repeat for each product or service, preserving quantity, unit, rate, and taxable value exactly as they appear. The DOCX remains fully editable so you can correct any OCR artefacts or add internal codes before saving the file.

Statutes and Rules Referenced on Invoices

GST invoices draw their mandatory content from the CGST Act, 2017 and the corresponding state acts, together with rules notified by the Central Board of Indirect Taxes and Customs. Section 31 of the CGST Act deals with tax invoices, while Rule 46 of the CGST Rules lists every field a compliant invoice must contain, from GSTINs and HSN codes to the place of supply and signature. The distinction between CGST‑SGST and IGST follows the Integrated GST Act, 2017, depending on whether the supply moves within one state or between states. For businesses above the prescribed turnover threshold, e‑invoicing under Notification No. 13/2020 – Central Tax adds mandatory IRP reporting. Separately, the e‑way bill framework under Rule 138 requires transport details for movement of goods above a specified value. This legal backdrop explains why invoices contain such a dense set of fields, each one exists for a specific compliance purpose.

How to Get a Duplicate Copy of an Original Invoice

When a paper invoice is lost, damaged, or illegible, the most reliable route is to request a duplicate from the supplier. A duplicate tax invoice, clearly marked as “Duplicate,” is permitted under GST rules and carries the same evidentiary value for ITC claims provided the original invoice number, date, and supplier details match. If the supplier is unresponsive or no longer in business, businesses often reconstruct the invoice from supporting records, purchase orders, goods receipt notes, lorry receipts, or payment vouchers, and get a typed version that captures all available data. Lekhak’s typing service can help create a clean DOCX from those reconstructed inputs, but the typed document alone cannot replace the original invoice for an ITC enquiry. In that situation you would still need to substantiate the transaction through other contemporaneous evidence as required by the tax authorities.

Frequently Asked Questions

What does Lekhak’s invoice typing service produce?

It gives you a clean, editable DOCX file that types out every visible field from a scanned paper invoice, supplier and buyer GSTINs, item descriptions, HSN codes, tax breakup, bank details, and transport information. The file is ready for accounting software or internal records.

Can the typed DOCX be used directly for a GST input tax credit claim?

The typed DOCX is a faithful reproduction for your records, not a replacement for the original invoice. For ITC claims you must retain the original or a valid duplicate, but a clear digitised copy makes matching with GSTR‑2B and internal reconciliation much easier.

Does Lekhak generate e‑invoices for the IRP?

No. The typing service outputs only a DOCX. An e‑invoice requires a digitally signed JSON generated through a GST Suvidha Provider or ERP system and reported to the Invoice Registration Portal; that is outside the scope of AI typing.

What file types can I upload for typing?

You can upload scanned PDFs, JPG, PNG, or WebP images. The platform handles multi‑page files; each page of the invoice is processed and typed out in sequence within the same DOCX.

How accurate is the AI on handwritten invoices?

From documents we have processed, the AI handles printed or clearly handwritten text well, but heavy cursive, faint ink, or overlapping stamps may cause minor errors. The DOCX is fully editable, so you can review and correct any fields before saving.

Does the service validate GSTINs or recalculate tax amounts?

No. The typing service reproduces what appears on the invoice exactly, it does not cross‑check GSTIN validity, re‑compute tax, or flag mismatches. You remain responsible for verifying the correctness of the original invoice data.

How long does invoice typing take?

Processing starts immediately after upload and the DOCX is ready to download within minutes. There is no queue or manual review step for the self‑serve typing flow.

Can I edit the typed DOCX after download?

Yes, the file is a standard Word document. You can adjust formatting, correct minor OCR artefacts, add internal reference numbers, or insert additional fields as your record‑keeping requires.

What if the paper invoice has multiple pages or line items?

The AI types every page and all line items into a single DOCX. Extensive line‑item tables are reproduced row by row, so you get a continuous, structured record of the complete invoice.

Is the invoicing data I upload stored by Lekhak?

You remain in control. Uploaded files are used solely to produce the DOCX and are not retained permanently. You can delete them from your account at any time after downloading the output.
