What it does

The GST month, from the files to the portal, and the arithmetic to back it.

fynxIQ builds the GSTR-1, holds your purchases against the GSTR-2B, drafts the GSTR-3B and hands the month to Tally. Then it spends most of its effort trying to prove the result wrong. What survives is a return you can defend line by line.

GSTR-1

Every table, named the way the portal names it.

Built from one ledger, and held against the offline tool’s own format rules before it is offered. Monthly or quarterly under QRMP, with the invoice furnishing facility in the first two months of a quarter.

Table 4A1 of 10

Registered buyers

One row per invoice, with items grouped by rate rather than by source line, which is what GSTR-1 expects and what most exports do not give you.

Bills from photos and PDFs

A bill book in the same return as the marketplaces.

The one kind of file read by a model, because no rule can read handwriting, and the one that has to earn its way in. The free plan reads 5 photographed bills a month.

Purchases and GSTR-2B

Which credit you can claim, bill by bill.

Since January 2022 credit can be taken only on invoices in your GSTR-2B (section 16(2)(aa), rule 36(4)). Each bill is matched on the supplier’s GSTIN and the bill number, and every document is told which side it is on.

Marketplace feesCommission and shipping invoices a marketplace raises on you are named by marketplace, so their credit is not lost.
GSTR-3B

A draft built from the documents, held against the portal’s own.

GSTR-3B is not output minus input. Its outward half is the month’s GSTR-1, its credit half is what the GSTR-2B makes available, with what the business reverses in between.

Set-off, in the order the Act fixes
1Integrated tax credit, first
2Central credit against central tax
3State credit against state tax
4Reverse charge, in cash
5TCS collected by marketplaces, against the cash that remains

Not in the draft: imports of services, interest and late fee, and credit from earlier months. The late fee has its own free calculator.

TCS statement

What each marketplace reported about you, before you file.

Every marketplace files a GSTR-8. Drop the portal’s TCS credit statement beside the month’s files, as Excel, and each operator’s figure is compared with your own, state by state; the PDF names no operator, so it checks the total. On real months every difference was accounted for.

Tally

The checked month, as Tally’s import file.

The books and the return become one set of figures. The sales files were tested by importing into a TallyPrime 7.1 company; import into a copy of yours the first time.

Staff, client by clientA staff member sees only assigned clients, enforced in the database reads rather than hidden on screen.
A link for the clientThey drop the month’s files without an account; what reaches you is the prepared return, never the files.
In and outImport clients from a spreadsheet, export everything as one zip, delete with seven days to change your mind.
The Month PackOne zip per client per month: the portal’s JSON, the GSTR-3B draft, the checks report, the fynxIQ Register and the Tally files once named, with every file’s SHA-256, so a copy found later can be checked against it.
The hard parts

Where marketplace exports mislead, and what we do about it.

None of these produces an error. Each produces a return that balances against itself and is wrong.

Across all of it

The parts that matter in month nine.

TraceEvery figure has an addressAny amount can be followed back to the file name and row number it came from.
HistoryA record of what you preparedTotals, counts and sources for every month, so a question three years on has an answer.
Any fileIt reads the file you actually haveA marketplace export, the GSTN offline template, or any sheet of your own, turned into one fynxIQ Register. A model only says which column is which; every figure is read by code and checked, and you confirm it.
Your languageIt asks in the language you readA genuinely ambiguous file gets a question with buttons, in any of fourteen languages, Hinglish included.
MapperOr with no model at allPoint the columns yourself, or copy your rows into the fynxIQ Register in Excel and drop it in. A mapping or a reading is kept for next month on Seller and above.
OperatorsOne GSTIN teaches it every stateSupply one TCS registration; the rest are derived from its PAN with a computed check digit.
Second opinionA reviewer, never a gateA model reads the findings back in plain language. It cannot clear a blocker or change a figure.
