Custom billing software
Custom billing software built around how your business charges customers.
We don't sell a billing app. We build billing and invoicing systems for businesses whose pricing, approvals or integrations don't fit ready-made tools — GST invoicing, subscription billing and payment collection, connected to the rest of your operations.
What we build
GST invoicing
Tax invoices generated from your data with the GST details your business needs on them, exported as branded PDFs.
Subscription & recurring billing
Plans, billing cycles and renewals handled by the system instead of a calendar reminder.
Payment gateway integration
Collect payments online through a payment provider and reconcile them against invoices.
Billing dashboards
Outstanding, paid and overdue at a glance, with the reports your accountant asks for.
Quotations to invoices
Turn an approved quotation into an invoice without re-entering the line items.
Integration with your systems
Billing connected to your CRM, product or operations tools through their APIs.
Proof, not promises
Built on a workflow we use ourselves
Our own studio admin generates quotations and invoices as PDFs from structured line items — the same pattern we extend into full billing systems with customers, payments and recurring schedules for clients.
How it works
No black box.
You see progress every week and approve every step. The full five-stage process is on the home page.
- 01
Map how you bill today
Pricing rules, approvals, tax handling and where the data comes from — before anything is designed.
- 02
Scope & fixed quote
A written scope covering invoices, payments, roles and integrations, with a fixed price.
- 03
Build & test with real cases
Weekly staging links, tested against your actual billing scenarios and edge cases.
- 04
Go live & support
Migration of existing customers and balances where needed, then optional ongoing support.
Pricing
A fixed quote before any work begins.
Billing systems are scoped per project under our High-End tier. We confirm your tax, payment and integration requirements in discovery, then quote a fixed price against a written scope. Please confirm compliance requirements with your CA — we build to the rules you specify.
FAQ
Common questions
Should we build custom billing software or buy a ready-made tool?
If a ready-made billing app fits your pricing and workflow, it's usually cheaper — and we'll say so. Custom billing makes sense when your pricing rules, integrations or approval steps don't fit, or when billing needs to live inside your own product.
Do you sell a billing product?
No. We build billing systems for individual businesses, designed around their workflow.
Can it generate GST invoices?
Yes — GST invoicing is part of what we build. Tax rules and invoice requirements should be confirmed with your CA during discovery so the system matches your obligations.
Can customers pay online?
Yes. We integrate payment gateways so customers can pay invoices or subscriptions online, with payments matched back to the right invoice.
