How to choose a GST invoice tool for MFDs: 9 checks before you trust one

A good tool runs hard validation checks on the finished set, and refuses to hand anything over if even one fails: every invoice numbered, dated and signed, the registrar's Excel sheet matching the PDFs exactly, no duplicates, the ZIP containing only what the registrar accepts. This matters because one bad file can get your whole upload rejected, and every rejection eats into the 7th to 15th window. MFD Office runs 12 such checks on every KFIN package and 8 on every CAMS package, and it is all or nothing: if any check fails, no package is produced and you are told exactly what went wrong.

The registrar has already computed your taxable amount and the CGST, SGST or IGST split. Any tool that retypes or recomputes those figures can introduce a mismatch, and a mismatch between your invoice and the registrar's records is exactly what gets uploads bounced. MFD Office takes every amount straight from the file KFIN or CAMS gave you and never retypes a figure, so a mismatch can never come from us.

Some months your brokerage report has negative rows, where commission was taken back. Under GST those need a credit note, not a tax invoice, and a tool that quietly turns them into invoices is producing documents that are wrong. MFD Office detects clawback rows, keeps them out of the upload package, tells you which rows they were, and points you to a step-by-step credit note guide.

The upload window is usually the 7th to the 15th of the month, and missing it delays the GST on that month's brokerage. A tool built around this work should know the calendar. MFD Office emails every active account a reminder on the 7th, the 12th and the 14th, so the window cannot slip past you.

Your brokerage file shows your entire earnings book, so it should not sit on someone's server. But your finished invoices are tax records you may need years later, so they should not vanish either. Be careful with slogans here: "we store nothing" and "your invoices are available for 12 months" cannot both be true, so ask for the specific answer for each kind of file. With MFD Office, your brokerage files are deleted right after your run, while your finished invoices stay safely in your account for whenever you need them.

You are handing over an image of your signature, which is exactly the kind of thing you do not want lying around as a plain file. Also read the vendor's terms: some make you carry all responsibility for how that signature image is used. MFD Office stores your signature encrypted at rest, decrypts it only for the seconds a run needs it, and wipes the decrypted copy with the run's working files.

You are buying this tool for your business, so you should get a GST tax invoice with the seller's GSTIN and be able to claim the input credit. It is also a simple honesty test: a vendor selling GST invoicing who cannot invoice you properly has told you something. MFD Office issues a GST tax invoice for every purchase, available in your Billing tab.

You are trusting this product with signed tax documents, so you deserve to know whose name is on it, in which city, and whether they understand the work. If a website names no company, no place and no person, ask why. MFD Office is run by FundsPundit, a mutual fund distribution business in Chennai. We file this same GST every month for our own ARN, and support is answered by people who do this work themselves.

A sample screenshot proves nothing. The only real test is your own registrar file going in and your own signed invoice coming out. MFD Office has a free preview where you upload your own KFIN or CAMS file and see one of your real invoices, with no signup and no card.
