Guided demo · sample data. This is a walkthrough of cbFinn, not a live account. Nothing here can be changed, and no one is emailed or charged.

Scene 1 of 10 · Introduction

Meet cbFinn

GST invoicing, payments, expenses and month-end, in one place.

Over the next few scenes you’ll follow one invoice from the moment it’s created to the day it’s paid, and then on to the month-end statement that goes to the CA. Every figure you’ll see is worked out by cbFinn, not typed in.

Scene 2 of 10 · Dashboard

The business, at a glance

Meera signs in to Demo Studio’s dashboard. Four numbers say where the money is: invoiced, received, outstanding and overdue. Drafts and cancelled invoices are never counted, so the figures are only real receivables.

  • Overdue invoices float to the top, with how many days late.
  • Due soon shows what should arrive next.
  • Recent payments, by mode: bank transfer, UPI, cheque.
  • Every status is a colour you learn once: sent, part paid, paid, overdue.

Scene 3 of 10 · Create

An invoice in under two minutes

Meera picks Northwind Retail, and cbFinn fills in their place of supply, payment terms and currency from the customer’s record. She adds three saved services, and the A4 preview on the right redraws from the same calculation the saved invoice will use, so what she sees is exactly what Northwind will get.

  • The invoice number is suggested from your own format.
  • Saved items bring their SAC code, unit, rate and GST rate.
  • Discounts per line, as a percentage or an amount.
  • Nothing is typed into a total: the server works every one out.

Scene 4 of 10 · GST

GST, worked out. Never by hand.

Demo Studio is in Maharashtra and Northwind is in Karnataka, so this is an inter-state supply and cbFinn charges IGST. Had Northwind been in Maharashtra, the same 18% would split into CGST and SGST. The total tax is worked out once and SGST is the remainder, so the two halves can never disagree with it, even by a paisa.

  • Place of supply is suggested from the customer, and can be changed per invoice.
  • GSTINs are checked for their format and check digit.
  • HSN/SAC on every line, and a rate-wise tax summary when rates are mixed.
  • Reverse charge is noted on the invoice. Round-off is your choice.
Customer in Karnataka: IGSTThe same invoice, customer in Maharashtra: CGST + SGSTSame tax, same total, either way

Every amount is held in whole paise, never as a floating-point number, and the calculation is tested against a real CA-issued invoice.

Northwind is in Karnataka, so the real invoice charges IGST. Next, it’s issued.

Scene 5 of 10 · Issue

The invoice your client actually receives

A draft can be changed freely. Issuing it makes it official: the number is taken from your sequence inside the same save, so a failed save can never leave a gap. The customer’s and your own details are copied onto the invoice, so editing an address next year never rewrites this one.

  • One template for the preview, the printout and the PDF.
  • A single A4 page, with the bank details and amount in words.
  • Issued invoices are never deleted: cancelling keeps them, with a reason.
  • Every action is recorded in the invoice’s activity.

Emailed, with the PDF and a way to pay

Send email opens with the recipient, subject and message already written. The PDF is generated fresh at that moment and attached, and cbFinn refuses to send an invoice email without it. Kavya receives a clean, branded email with the amount due and a Pay Now button.

  • Sent from your own business mailbox, not a no-reply address.
  • Pay Now is a Razorpay payment link for exactly the balance due.
  • CC your customer’s accounts team, or your own.
  • The invoice moves to Sent, and the send is logged.

Scene 8 of 10 · Expenses & reports

Money in, money out, and what’s left

Rohan, the accountant, logs the month’s spending with its receipts: rent, software, travel, the CA’s own fee. Reports then puts it next to what was actually received, for a cash-basis view of the month, with the GST summary your CA files from, split by rate into CGST, SGST and IGST.

  • Categories are yours to name. Receipts can be PDFs or photos.
  • Receipts are stored privately, never at a public link.
  • Net is cash basis: money received, minus money spent.
  • Filter any report by dates or by customer.

Scene 9 of 10 · Month-end

Month-end, sorted in one click

At the bottom of Reports, Meera picks the month and sends it. Her CA gets a proper Excel workbook, not a CSV: a Summary sheet, every payment received and every expense, in rupees with Indian digit grouping and a frozen header row, ready to work from.

  • Three sheets: Summary, Income and Expenses.
  • Download it yourself, or email it straight to your CA.
  • Your CA’s address lives in Settings, once.
  • Give your CA a Viewer sign-in to look at everything, change nothing.
