Features
Everything between the work and the money.
Invoices, GST, documents, payments, expenses and month-end, built around one rule: no figure reaches an invoice unless cbFinn worked it out.
Invoicing
Invoices in a couple of minutes
Customers and items are saved once, so an invoice is mostly choosing, not typing.
- Customers with their GSTIN, PAN, billing and shipping address, payment terms, currency and place of supply.
- A catalogue of goods and services with HSN/SAC, unit, rate and GST rate.
- Discounts per line, as a percentage or an amount. Round-off to the rupee if you like.
- Tax invoices and proforma invoices, drafts, and Duplicate for repeat work.
- Your numbering format (prefix, financial year, sequence), reset each financial year.
- Payment terms from due on receipt to 90 days, with the due date worked out.

Tax that’s right to the paise
cbFinn works GST out the same way every time, and makes no legal judgement on your behalf: where one is needed, it’s a setting, marked for your CA.
- IGST, or CGST + SGST, decided by comparing your state with the place of supply. Override it per invoice.
- SGST is the total tax minus CGST, so the halves always add up to it exactly.
- Every amount held in whole paise, never floating point, and tested against a real CA-issued invoice.
- GSTINs checked for their format and check digit. Unregistered customers work too.
- A rate-wise tax summary on the invoice whenever rates are mixed.
- Reverse charge noted on the invoice; amounts in words in lakh and crore.

Documents
The preview is the PDF
One A4 template serves the live preview, the printout and the PDF, so there are no surprises between what you check and what your client opens.
- Your logo, GSTIN, bank details and terms on every invoice.
- Signed with an uploaded signature image, or a note that it’s digitally issued.
- Print, or download a true A4 PDF.
- Issued invoices are locked: never deleted, only cancelled with a reason, and the number is never reused.
- Your details and your customer’s are copied onto the invoice, so later edits never rewrite it.
Sending & payments
Sent properly, paid visibly
Email the invoice in a click, give your client an easy way to pay, and always know what’s still due.
- Emailed with the PDF attached, from your own business mailbox, with CCs. It won’t send without the PDF.
- A Pay Now button: a Razorpay payment link for exactly the balance due.
- Record payments by bank transfer, UPI, cash, cheque or card, with a reference, in full or in part.
- Statuses that follow the money: Draft, Issued, Sent, Partially Paid, Paid, Overdue, Cancelled.
- Remove a payment recorded by mistake, and the balance is restored.
- A Payments list of everything received, across every invoice.

Security
How cbFinn protects your data
Every rule is checked by the server on every request. Hiding a button is never what protects your data.
-
Passwords
Stored only as one-way hashes. New passwords need at least 10 characters, and the first sign-in forces a change.
-
Signing in
A failed sign-in never reveals whether an account exists, and deactivated users can’t sign in.
-
Sessions
A new session at every sign-in, an HttpOnly, SameSite cookie (Secure over HTTPS), and automatic sign-out after inactivity.
-
Every change
Each form carries a security token that’s checked before anything is saved.
-
Roles
Owner, Accountant and Viewer, checked by the server on every page and every action.
-
Audit trail
Who did what and when, from which IP address and browser.
-
Receipts
Checked by their content, not just their name, stored away from the public web, and shown only to people who are signed in.
-
Invoice records
Numbers never skipped or reused; issued invoices never deleted; details copied onto each invoice when it’s saved.
-
Email
Mailbox passwords live in the server’s configuration, never in the database or the browser.
-
Payments
Pay Now opens Razorpay’s own payment page, so card and UPI details never reach cbFinn.
