I will build an invoicing, billing and subscription system


Over deze dienst
Still tracking invoices and subscriptions in spreadsheets, or using tools that don't quite fit?
Billing is one part of your product you can't afford to get wrong. A miscalculated tax line or broken proration doesn't just cost money it costs customer trust. This needs real billing logic, not just code.
With production experience building invoicing and subscription modules for enterprise platforms, I handle the edge cases tutorials skip proration, failed payments, multi-currency, compliance-ready reporting.
What I'll build:
- Automated invoice generation (one-time & recurring) with PDF export
- Two-way invoicing system if required (sales vs. purchase invoice)
- Subscription billing plans, upgrades/downgrades with proration, trials, auto-renewals
- Payment gateway integration (Stripe, PayPal, JazzCash, EasyPaisa, Safepay)
- Multi-tenant support for isolated client billing
- Revenue & tax reports or all other required reports exportable to Excel/PDF
You'll get a fully functional system connected to your database, secure backend logic, documented code, and sandbox testing before go-live.
Message me first if integrating into an existing app or for specific tax/compliance needs.

Veelgestelde vragen
Is this suitable for B2B or B2C businesses?
Both, I build the billing logic around your actual business model, whether that's enterprise client invoicing or consumer subscription billing.

Yes, I can connect this to an existing MongoDB/SQL database and Node.js/Express backend or build the full stack from scratch.
Which payment gateways do you support?
Stripe and PayPal internationally, plus JazzCash, EasyPaisa, and Safepay for Pakistan-based businesses.

Yes, this can be added as a custom extra message me with your region's requirements first so I can scope it accurately.
What happens if a customer's payment fails?
The Premium package includes automatic retry logic and reminder notifications (dunning) so failed payments don't silently churn a customer.
