Billing and subscriptions recurring billing and subscription management

Recurring billing looks simple until you add upgrades mid-cycle, usage charges, credit notes and failed mandates. We build billing that handles those cases correctly, issues GST compliant invoices and tells finance exactly what is owed and why.

Modules

Modules we build into your Billing and subscriptions

Start with the modules that matter most and add the rest in later releases.

Plans and pricing
Flat, tiered, per seat and usage pricing, add-ons, coupons and price changes with grandfathering rules.
Subscription lifecycle
Trials, upgrades, downgrades, pauses and cancellations, with proration worked out the same way every time.
Usage metering
Collects usage events from your product, rates them against the plan and shows customers a running bill.
Invoicing and GST
Tax invoices with GSTIN, place of supply and HSN or SAC codes, e-invoicing through the IRP where your turnover requires it.
Mandates and collections
UPI Autopay, e-NACH and card mandates, with the pre-debit notices RBI rules ask for and smart retries on failure.
Dunning and credit control
Reminders by email and WhatsApp, grace periods, service suspension rules and credit notes.
Revenue reports
MRR, churn, deferred revenue and ageing, reconciled with what actually landed in the bank.

AI built in

Where AI saves time in this system

  • Churn risk signals

    Flags accounts with falling usage, repeated payment failures or support complaints so someone can reach out.

  • Billing query answers

    Explains a customer's invoice line by line from the billing record, and hands over to finance when it cannot.

  • Reconciliation matching

    Matches gateway settlements and bank credits to invoices and lists the ones that need a person.

  • Pricing analysis

    Shows how a proposed price change would affect existing customers before you publish it.

Build, buy or both

If your pricing is a handful of plans and you collect by card or UPI, Razorpay Subscriptions, Stripe Billing or Zoho Subscriptions will do the job for a fraction of the cost of building. Custom or hybrid pays off when pricing is your product (usage, contracts with commitments, partner revenue share), when you bill across many entities and GSTINs, or when finance spends days reconciling. We usually keep the gateway's mandate handling and build the rating, invoicing and reporting around it.

Questions

Billing and subscriptions: common questions

Can we keep Razorpay or Stripe?

Yes, and in most cases you should. They handle card storage and mandate rules well. We build the billing logic on top.

Do you handle GST e-invoicing?

Yes. B2B invoices can be registered with the IRP directly or through your GSP, and the IRN and QR code are printed on the invoice.

How do you sync with our accounts?

Invoices, receipts and credit notes post to Tally or Zoho Books as vouchers, so your accountant works in the tool they know.
