Collect

Every way your customers pay, in one place

Online or at the counter, in full or in parts. Each payment is matched to its invoice and posted to the books on its own.

Payment links on invoices

Add a UPI, card and netbanking link to any invoice through your own Razorpay account.

Checked with the gateway

An invoice is marked paid only after Razorpay confirms the payment, never on the customer's word.

Cash, cheque and bank too

Record offline payments against one invoice or spread across several.

Part-payments and advances

Partial payments keep the balance open; overpayments become credit for the next bill.

Receipts sent for you

Every payment emails the customer a receipt with the amount and what is still due.

Refunds that reverse cleanly

Reverse a payment and the invoice reopens with a matching ledger entry.

Reminders

Reminders that go out without you

Set the schedule once. Each overdue invoice moves through it step by step, and stops the moment it is paid.

  1. 01

    Invoice sent

    The customer gets the invoice and a payment link by WhatsApp or email.

  2. 02

    First reminder

    A few days past due, a polite email goes out with the amount and the link.

  3. 03

    Second reminder

    If it's still open, the next step follows, and you get an in-app alert.

  4. 04

    Final reminder

    The last step goes out; the party shows up on your overdue list for a call.

Reminder emails go out once per step, never twice in a day. Payments through a link stop the schedule straight away.

Receivables

Know who owes you, and since when

Ageing, statements and credit limits come from the same invoices and payments, so the number your CA sees is the number you see.

On every customer's account

  • A statement of invoices, payments and credit notes for any date range
  • Outstanding split into ageing buckets: current, 30, 60, 90 and 90+ days
  • Payment terms and a credit limit that blocks over-limit bills
  • Available credit from advances and overpayments
  • Notes and a timeline of every invoice, payment and note

Send

Send it the way your customer prefers

  • WhatsApp

    Share the invoice and its payment link in the chat your customer already uses.

  • Email

    Branded invoice emails from your business name, with open tracking.

  • Customer portal

    A private link where customers see their invoices and statement, and pay online.

  • Recurring auto-charge

    Monthly or weekly invoices go out with a fresh payment link each cycle.

Payables

And the other side: what you owe

Supplier bills, payments and advances sit on the same books, with supplier ageing to plan what to pay this week.

  • Supplier ageing

    See what's due to each supplier, bucketed by age, before you plan payments.

  • Advances to suppliers

    Prepayments are held as supplier advances and set off against the next bill.

  • Bills matched first

    Bills are checked against the PO and goods received, so you pay only for what arrived.

Questions

Questions about payments

Something not covered here? Call or WhatsApp us and you'll speak to the people who build the product.

Create a payment link on the invoice and send it with the invoice by WhatsApp or email. The customer pays by UPI, card or netbanking through Razorpay, and once the gateway confirms the payment the invoice is marked paid.

Yes. Payment links run on your own Razorpay account, so settlements go to your bank account on Razorpay's schedule. We never hold your money.

Yes. Record any payment against one or more invoices. Part-payments leave the balance open, and extra money becomes credit the customer can use later.

Overdue invoices move through a reminder schedule you set, for example 3, 7 and 14 days. At each step the customer gets an email and you get an in-app alert, once per step, so nobody is chased twice in a day.

Yes. Give the customer a credit limit. A new invoice is blocked when their outstanding plus the new bill would cross it.

Reverse the payment and the invoice opens again, with a matching entry in the ledger, so the books stay right.
