Nothing is final until the agreement is signed and payment is made. Prices on the website are indicative; the proposal and agreement confirm the final price. Subscription eligibility is subject to Terrapin Software's terms and conditions.

Free plans

Free plans (for example, 2 users at one location on free apps and the Billing free plan) need no proposal or payment. You accept the terms and conditions when your account is set up. When you add users, locations or features beyond the free plan, the paid steps above apply.

Paying

  • Subscriptions are annual and paid in advance against the proforma invoice.
  • Pay by bank transfer, UPI or the payment link shared with the proforma invoice. Payment details are on the proforma invoice only; Terrapin never asks for card numbers, passwords or OTPs over chat or phone.
  • GST is charged in addition to the fees.
  • Third-party usage (WhatsApp, SMS, email, voice, AI, gateway and courier fees) is billed at actuals, separately.

Adding users, locations or products

Need more users, another location or another product during the year? Tell your Terrapin contact. We confirm the change and the amount, then issue a new sales order, proforma invoice, receipt and tax invoice for it.

Renewal

Before your subscription ends, we send a renewal proposal. Once you accept it, the same documents follow: sales order, proforma invoice, payment receipt and tax invoice, so there is no break in service.
