What VyaparSetu does

Each of these is implemented and tested against the rule it encodes. Nothing here is a roadmap.

GST returns

Prepare, check and file GST returns from the books, with the rules the law sets.

GSTR-1
All sections, HSN summary and the documents-issued table, built from invoices in the books.
GSTR-3B
Derived from GSTR-1 and the saved GSTR-2B, with the statutory ITC set-off order (sections 49(5), 49A, 49B and Rule 88A), imports, ISD, reverse charge and reversals.
GSTR-2B reconciliation
Three-way match of the purchase register against GSTR-2B; every document classified and an IMS action recommended with a reason.
IMS decisions
Accept, reject or keep pending each supplier invoice; a person's decision is never overwritten by a re-run.
QRMP
Quarterly GSTR-1 and 3B with monthly PMT-06, IFF for months one and two, and state-wise due dates.
Composition scheme
CMP-08 and GSTR-4 dates, bill of supply, and screens that say plainly what a composition dealer must not file.
Proceed to file
SAVE → SUBMIT → FILE with EVC, as a state machine with server-side gates — a filed return refuses further action.
Filing guardrails
The three-year filing bar, the 30-day e-invoice window, GSTR-3B hard-locking and the portal's API-access grant are checked before anything is transmitted.
Return check
A filed GSTR-1 or 3B, read from the portal PDF or fetched through the GSP, compared against the books: what was left out, which customers' credit is blocked, by when it can still be put right, and what would be paid twice.

e-Invoicing and e-way bills

Register invoices with the IRP and move goods legally.

INV-01 and IRN
Every mandatory field checked before transmission; idempotent so a retry never becomes a second report.
Signed QR
The IRP's signed QR read directly — exact GSTINs, number, date, IRN and total — for the fast path into the books.
Cancellation
Within the 24-hour window; afterwards the product says to reverse with a credit note.
e-Way bills
Thresholds by state, validity by distance, Part A and Part B kept apart, the 180- and 360-day limits enforced.

Collections and receivables

Get paid: know who owes what, chase on WhatsApp, and record what arrives.

Receivables ageing
Buckets, DSO, credit limits and who to chase first, by money at risk.
Dunning ladder
Reminders that escalate in tone, start before the due date, pause on a promise to pay and end with a person.
WhatsApp, direct
Meta's Cloud API without a middleman, using approved templates.
Consent and opt-out
Opt-in recorded where it was captured; opt-out is absolute; one contact per debtor per day.
Promises to pay
A recorded promise pauses the ladder; one open promise per invoice.
Payments received
Cash, UPI, NEFT, cheque or a Razorpay link — matched to the invoice and posted to the ledger.
Payment rails
Razorpay payment links and virtual accounts on every reminder.
Section 43B(h) monitor
MSME supplier payments tracked against the 15/45-day deadline that decides tax deductibility.

Books and ledger

A correct set of books underneath everything, kept by the system.

Double-entry ledger
Journal entries, trial balance and fiscal periods; postings are never edited, only reversed.
Gapless numbering
Invoice series per financial year and GSTIN with no gaps.
Effective-dated GST rates
Every rate resolved against the document date; an abolished slab cannot be applied to a current invoice.
Hash-chained audit log
Every change recorded in an append-only chain that can be verified.
Inventory
Stock moves when documents are confirmed; weighted-average or FIFO valuation; reorder planning against cash.

Getting documents in

Bring what exists — bills, statements, another system's books — without retyping.

Zoho Books
Each business connects its own account; customers, items, invoices, bills, payments, journals and bank lines come across, then a nightly sync keeps them in step.
Tally
Import a Tally XML export from the web or the phone; vouchers become documents in the Inbox, deduplicated.
Spreadsheets
A sales or purchase register in Excel or CSV, mapped, validated and reviewed before posting.
Email intake
A private per-business address suppliers send bills to; unknown senders are held, not dropped.
Bank statements
Statement import with matching to open invoices.

Cash and planning

See what is coming and what can be afforded.

Cash forecast
Receivables, payables and learned running costs projected forward.
Reorder planning
What to reorder this week without creating a cash deficit, with lead times.
Quote comparison
A supplier quote against the previous six purchases.
Lender packet
The documents a lender asks for, and a readiness check before asking.

Ask, in your language

Ask the business a question and get an answer grounded in the books.

Voice and text
Ask on the web or the phone; the question is understood in the language it was asked in.
Eleven languages
Answered in English, Hindi, Bengali, Gujarati, Kannada, Malayalam, Marathi, Odia, Punjabi, Tamil or Telugu, and read aloud.
Grounded answers
Every rupee figure comes from a computed result; an unsourced number is refused rather than spoken.
Collect everything overdue
One instruction ranks the overdue book and sends every reminder that is due — after a person confirms.

Integrations

Connect the books to the tools already in use.

Zapier
Seven triggers (new invoice, invoice paid, new bill, new payment, new customer, new supplier, new promise), two actions (create customer, create invoice with GST computed), three searches — with ready-made setups for Google Sheets, Slack, Gmail, Google Calendar, Google Forms and Shopify.
API
The same per-business key works from anything that speaks HTTP; amounts in rupees, rates in percent.

Security and compliance

Built for data other people are entitled to rely on.

Row-level security
The database is the tenant boundary; one business cannot read another's rows even through a bug.
Mobile-OTP sign-in
The GST-registered mobile is the identity.
DPDP
Consent records, data-principal requests with a 90-day SLA, retention floors, legal holds and a breach register.
Credentials stay server-side
GSP keys, the WhatsApp token and payment secrets never reach a browser or a phone.

Languages: English, Hindi, Bengali, Gujarati, Kannada, Malayalam, Marathi, Odia, Punjabi, Tamil, Telugu. Platforms: Web and Android.
