Overview
Subscription businesses need billing logic that handles plan changes, proration, trials, coupons, usage-based components, invoicing, tax calculation and revenue reporting. We build subscription billing systems — or integrate and extend billing platforms — for SaaS, media and consumer subscription businesses, connected to payment processing and accounting.
Common use cases
- SaaS billingSeat-based and usage-based SaaS plans.
- Media subscriptionsConsumer subscriptions with trials and bundles.
- Usage-based APIsMetered billing for API products.
- B2B invoicingContract-based invoicing with payment terms.

Frequently asked questions
Build billing or use a billing platform?
Billing platforms suit standard models; custom billing suits unusual pricing, complex contracts or scale economics. Hybrid approaches are common.
Can you support usage-based pricing?
Yes, with high-volume metering pipelines and transparent usage reporting for customers.
Do you process payments directly?
No. Shivacha builds the software; payments are processed by licensed acquirers, PSPs and banks that you contract with. Our platforms integrate and orchestrate those providers.
Can you help reduce payment failures?
Yes, through smart routing, retries, network tokenisation, local payment methods and analytics on decline reasons — all subject to your provider agreements.
