Does PDF Duplicate Review give a GST invoice in India?

Whether PDF Duplicate Review issues an India GST invoice is not verified yet. Foreign-billed tools usually don't, in which case a registered business reclaims GST via reverse charge; confirm the vendor's billing before you buy.

Is PDF Duplicate Review good for Indian small businesses?

It suits accountants, CAs and office admins deduplicating folders of PDF invoices or statements before archiving. It bills in a foreign currency, so expect the card forex markup on every charge. It is not the right pick for folders of scanned or image-only PDFs, since there is no OCR or visual comparison.

Does PDF Duplicate Review have a free plan?

PDF Duplicate Review lists a free plan, but check the official pricing page for current usage limits before choosing it.

FindThatSoftware verdictEditorial ruling

Shortlist it if you are clearing out a folder of PDF invoices, contracts or statements and want proof of which files are exact copies before you delete anything, without uploading client documents to a web service. Try the free 10-file batch first on a sample of your real files, because scanned PDFs, password-protected files and anything over 500 pages are reported for attention rather than compared.

Read the full verdict

Before paying, note that the price is set in euros with tax included; the checkout we saw from India showed a rupee total with GST broken out as a line inside it, and the vendor does not say whether you get a GST invoice with your GSTIN on it. The product is days old (version 1.0.0, no store reviews yet) and the Chrome Web Store listing names an individual developer in the Netherlands while the website names a Georgian company as owner, which the vendor says is a verification step in progress. The obvious alternative is a free desktop duplicate finder that hashes files, which covers exact copies well; this tool's extra is the separate same-text match and the CSV audit trail.

In short

PDF Duplicate Review is listed under E-signature & Documents, reviewed for Indian buyers. All-in it runs about ₹4,570 one-time for a GST-registered business (€49 one-time sticker plus about 3.5% card forex). FindThatSoftware rates it best for accountants, CAs and office admins deduplicating folders of PDF invoices or statements before archiving; a poor fit for folders of scanned or image-only PDFs, since there is no OCR or visual comparison.

The rupee price a business actually pays, after the card forex markup, with GST shown both ways.

True India price

Registered business, one-time

₹4,570

PDF Duplicate Review is priced one-time at €49. For a registered business that lands around ₹4,570 once the roughly 3.5% card forex markup is added, GST reclaimed. Without reclaim, about ₹5,393.

Sticker price: €49
Card forex markup: about 3.5% over mid-market
GST: 18%, reclaimable if registered
Registered one-time: ₹4,570
If you can't reclaim GST: ₹5,393

Try first: Has a free plan, so you can start without a card.
Watch for: Pro is a one-time charge for version 1 set in euros with tax included, sold through a hosted Dodo Payments checkout; from India that checkout displayed the price in rupees with a separate GST line, so the rupee amount depends on the exchange rate.
More
The vendor says version 1 has no recurring fee, but future major versions and unlimited support are not promised. A full refund can be requested by email within 14 days, and it deactivates the licence.

Indicative, not a bill. The exchange rate is a single mid-market reference, not a live feed, and GST-registered businesses may reclaim input credit. Confirm current pricing on the vendor site.

Who PDF Duplicate Review fits

What it is, what you gain, what you give up, and who should look elsewhere.

What is PDF Duplicate Review?

PDF Duplicate Review is a Chrome extension from Kastovia Holdings LLC, a small software and automation company registered in Tbilisi, Georgia in June 2026. You pick PDFs or a folder, and it groups files two ways: byte-identical copies found by a SHA-256 hash, and files whose page count and normalized extracted text match page by page. The vendor says all reading and comparison happens inside the extension, nothing is uploaded, and source files are never deleted, renamed or rewritten; you get a CSV report listing candidate groups, the match basis, skipped files and errors. The free version handles up to 10 PDFs per batch, and a one-time Pro licence for version 1 raises that to 250 PDFs across up to three browser installs, with an online licence check before each larger batch. It has hard per-file and per-batch limits (20 MiB and 500 pages per PDF, 200 MiB per batch) and no OCR or image comparison, so scanned PDFs are flagged for attention rather than matched.

What you gain, and what you give up.

The case for

The vendor says PDFs, filenames, extracted text and hashes stay on your device and are never uploaded
Keeps exact byte copies and text-only matches as clearly separate results, so a text match is not mistaken for proof
Free tier needs no account, and Pro is a one-time payment for version 1 with a 14-day refund window

The catch

Very new: the company was registered in June 2026, the extension is version 1.0.0 with no Chrome Web Store ratings yet
Ownership is split across two names: the website and terms name Kastovia Holdings LLC in Georgia, while the Chrome Web Store lists an individual trader with a Netherlands address, which the vendor says is pending Google verification
Priced in euros with tax included and no stated GST invoice; the Indian checkout we saw showed a rupee total with GST broken out, but nothing confirms a GSTIN-bearing invoice
No OCR, no image comparison, no near-duplicate matching, and Pro needs an internet licence check before every batch over 10 files

Best for

Accountants, CAs and office admins deduplicating folders of PDF invoices or statements before archiving
Legal and records teams that need a CSV record of which files were exact copies versus text-only matches
Anyone who cannot upload confidential PDFs to an online duplicate checker

Who should avoid it

Folders of scanned or image-only PDFs, since there is no OCR or visual comparison
Large document stores of thousands of files, since even Pro caps a batch at 250 PDFs and 200 MiB
Teams wanting automatic cleanup, since the tool only reports and never deletes or merges
