Step 1

Set up your business

Tell PaarDarshi who you are once. Your GSTIN, address, bank and UPI details, logo and invoice preferences go on every invoice automatically, and issued invoices keep a snapshot, so later changes never alter them.

GST registration. Your GSTIN is checked for format and check digit; your PAN is filled in from it.
Invoice numbering. A prefix, the financial year and a sequence, e.g. WPS/26-27/0001. Numbers are given only when an invoice is issued, so they never skip.
Payment details. Bank account and UPI ID are printed on invoices, with a UPI QR code that has the amount filled in.
Team. Invite colleagues with the right role; your accountant gets read-only access plus exports.

WePDF Solutions did this

Invoice numbers: WPS/26-27/0001 onwards
Payment terms: 15 days
Exports: LUT ARN AD360426004512K, so overseas invoices carry no IGST
Team: Aditi Rao (Owner), Karthik Menon (Admin), CA Lakshmi Iyer (Accountant), Fatima Siddiqui (Staff)

Your turn: sign up, then the setup wizard takes about three minutes. You can finish it later.

Step 2

Add customers and services

Save each customer with their GST treatment and each service with its SAC code, rate and GST. After that, an invoice is a few clicks: pick the customer, pick the services.

GSTIN lookup. Type a customer's GSTIN and fetch their registered name and address; cancelled registrations are flagged.
Place of supply comes from the customer's state, which decides CGST + SGST (same state) or IGST (another state).
Overseas clients get their country and currency; SEZ units are marked so their supplies are zero-rated.
WhatsApp consent is recorded per customer before any WhatsApp message is sent.

WePDF Solutions did this

12 customers: 6 GST-registered businesses, 3 overseas clients (United Arab Emirates, United Kingdom, United States), 1 SEZ unit and 2 individuals. 4 agreed to WhatsApp messages.

Your turn: add your top three customers and the services you bill most.

Add a customer

Step 3

Create and issue invoices

Pick the customer and services; quantities, discounts and GST are calculated as you type by the same engine that prints the PDF. Save a draft, or issue it: issuing assigns the number and locks the invoice, as GST rules expect.

Step 6

Follow up automatically

Reminders go out on schedule (here: 3 days before the due date, then 1, 7, 15 days after), by email and WhatsApp, and stop the moment an invoice is paid. The dashboard shows what is due, overdue and how long each customer takes to pay.

WePDF Solutions did this

190 reminders sent automatically, 5 by the team. Outstanding today: ₹19,01,788.74, of which ₹10,84,597.00 overdue on 8 invoices.

Step 7

Bill clients abroad

Invoice overseas clients in their currency with the INR exchange rate. Under a Letter of Undertaking the export is zero-rated (no IGST) and the invoice carries the required declaration. When the money arrives, record what the bank credited in INR and the FIRA that proves it.

Step 8

Close the month

Everything you invoiced and collected is already in PaarDarshi, so month-end is downloads, not data entry: the GSTR-1 file for the GST portal, a Tally file for your accountant, and reports for you.

WePDF Solutions: invoiced and collected by month (INR)

* Current month, to date. Collections include TDS deducted by customers.

GSTR-1 for Oct 2026

Section	Docs	Taxable value	Tax

B2C small (7), net of credit notes	1	₹5,42,700.00	₹97,686.00

Plus the HSN/SAC summary and documents issued. Download the JSON, review it in the GST offline tool and file. PaarDarshi prepares the file; you stay in control of filing.

GSTR-1 JSON: B2B, B2C, exports, credit notes, HSN summary and documents issued, monthly or quarterly.
Tally XML: customer ledgers plus sales, credit note and receipt vouchers (TDS split out), in your ledger names.
Reports: sales, payments, outstanding, ageing, GST summary, TDS by quarter, exports and FIRA, CSV exports.
e-Invoicing (above the turnover limit): the IRP file per invoice or in bulk; the IRN and QR print on the invoice.

Your turn: invite your accountant; they can download GSTR-1 and Tally files themselves.
