Is this Mushak 6.3 generator free?

Yes. It is free, there is no sign-up, and it runs entirely in your browser. Nothing you type is uploaded or stored.

Is a document from this tool an official NBR form?

No. It is a generated document laid out from the publicly published structure of the Mushak 6.3 challan. It is not certified by NBR, not filed with anyone, and should be checked with your VAT consultant before you issue it to a buyer.

Can I use it to issue real tax invoices?

You can print it and use it as a working document, but understand what it does not do: it does not allocate or protect your challan sequence, it does not keep your sales register, and it does not remember anything between visits. Those are the parts an audit turns on.

How does it calculate VAT and supplementary duty?

Line value is quantity times unit price, excluding tax. Supplementary duty is applied to that value first, and VAT is charged on the SD-inclusive figure, which is the statutory order. Reversing the two understates the VAT base.

Does it save my data?

No. There is no server, no account and no storage. Closing the tab discards everything, so print or save as PDF before you navigate away.

Is BizRP approved by NBR?

No, and this site does not claim it is. BizRP keeps the Mushak 6.3 and 6.1 registers, allocates challan numbers in an unbroken sequence, and computes the Mushak 9.1 figure. Filing is done by a person on vat.gov.bd.

The short answer

This tool lays out a Bangladesh Mushak 6.3 VAT tax invoice from the fields the form requires: supplier and buyer with both BINs, the challan number and date, each line with supplementary duty applied before VAT, the totals, the amount in words and the declaration. It prints, so you can save it as a PDF.

This is a generated document, not a certified NBR form. Nothing here is filed with or approved by NBR. Verify the layout and every figure with your VAT consultant before you issue it to a buyer.

What this produces, and what it does not

The tool lays out the information a Mushak 6.3 tax invoice carries: the supplier block, the buyer block, the challan header, the line items with supplementary duty applied before VAT, the totals and the amount in words, and the declaration. It renders to print, so you can save it as a PDF from your browser.

It is also not a numbering system. It will happily print whatever challan number you type, and the sequence is the part an audit actually turns on. If you are issuing invoices regularly, the sequence belongs in a system that allocates it, not in a browser tool.

Where your data goes

Nowhere. The tool runs entirely in your browser. There is no account, no upload, no server call, and nothing is stored between visits. Close the tab and the data is gone, which also means you should print or save before you navigate away.

That matters here specifically: filling a tax invoice means typing a real customer's name, address and BIN, and an online tool that quietly collects those is a genuine problem rather than a theoretical one.

How to fill each field

The full field-by-field reference, including a worked example and the error each field most often attracts, is on the Mushak 6.3 explainer. The short version is below.

Blocks of the Mushak 6.3 challan and what each requires
Block	Fields	The one thing to get right
Supplier	3	The legal name and BIN exactly as registered, not a trading name.
Buyer	3	A correct BIN when the buyer is registered. A wrong one costs them their input-tax claim.
Challan header	3	The next number in an unbroken sequence, and the real date of supply.
Line items	8	The rate the supply actually carries, and a price entered exclusive of tax.
Declaration	3	Words and figures that agree, and a named person rather than an anonymous signature block.

The mistakes this tool cannot save you from

The layout is the easy part. These are the failures that actually cost money, and most of them are about the sequence and the counterparty rather than the document in front of you.

A gap in the challan sequence. Auditors read a gap as a suppressed sale, and the burden of explaining it is yours.
A wrong or lapsed buyer BIN. The buyer loses the input-tax claim and comes back to you for a reissue you may no longer be able to make cleanly.
The wrong rate on a truncated-base service, in either direction.
Supplementary duty applied after VAT instead of before it, which understates the VAT base.
A VAT-inclusive figure typed into a field the form treats as exclusive.
Issuing the challan days after the supply, so the document date and the movement of goods disagree.
Line totals that do not reconcile to the column totals.
Discarding challans before the retention period is up.

Keep every challan you issue for 5 years, together with the register it lands in and the return it rolls into.

Doing this at volume

A generator is the right tool for an occasional invoice or for checking what the document should contain. It is the wrong tool once you are issuing daily, because the three things that matter at volume are the ones a form cannot do: allocate the number, keep the register, and produce a period figure that reconciles.

What BizRP does here

At the counter, BizRP allocates a gapless Mushak 6.3 number from an operator-configured series inside the transaction that completes the sale, so a sale cannot reach completed without one, a rollback returns the number rather than burning it, and a void keeps its number and is marked voided. Credit sales land in the same register carrying their sales invoice number from a separate sequence, not from that series, and cancelling a credit invoice does not currently mark its register rows voided. Every line of both channels lands with its taxable value, VAT rate and VAT amount, and the period exports as CSV in NBR column order. Two limits to know: supplementary duty is recorded as zero on every row today, so a business levying SD cannot rely on this register for it, and the buyer's BIN is captured at the counter but not yet on credit sales.

BizRP does not file returns. It produces the registers and the return figure; a person signs in to vat.gov.bd and submits.

BizRP is not enlisted with NBR as VAT software, and nothing on this site should be read as claiming that it is. What it does is keep the registers and compute the figures that a filing is built from.
