Custom Invoice & Billing System
Your pricing model is unique. Your billing system should be too.
QuickBooks, FreshBooks, and Stripe Billing work great for simple pricing. But if your business has usage-based pricing, tiered plans, complex discount structures, multi-currency requirements, or hybrid billing models, you're constantly fighting your billing tool.
A custom billing system handles your exact pricing model — whether that's consumption-based, milestone billing, retainer-plus-overage, or something entirely unique. Automated invoice generation, payment processing, revenue recognition, and the specific reports your finance team needs.
We build billing systems for SaaS companies with complex pricing tiers, professional services firms with project-based billing, and any business whose revenue model doesn't fit neatly into off-the-shelf invoicing templates.
What You Get
Your Pricing Model
Usage-based, tiered, per-seat, milestone, hybrid — built for your exact pricing structure, not a generic template.

Automated invoice generation on your schedule. Handle prorations, upgrades, downgrades, and mid-cycle changes.
Payment Processing
Stripe, Square, or direct bank integration. Automated payment collection, retry logic, and dunning management.
Multi-Currency

Revenue Reporting
MRR, ARR, churn, revenue by product/client/region — the specific metrics your finance team needs for forecasting.
Accounting Integration
Sync with QuickBooks, Xero, or your accounting system. Automated journal entries, tax calculations, and reconciliation.
When Custom Billing Makes Sense
If you send simple invoices for fixed amounts, FreshBooks or QuickBooks is fine. Custom billing systems are for businesses with pricing complexity that off-the-shelf tools can't model.
Signs you need custom billing: your finance team manually calculates invoices before entering them in your billing tool, you're losing revenue due to billing errors, your pricing model has changed but your billing system hasn't kept up, or you need billing data that feeds directly into your product.
Common Pricing Models We Build For
Usage-based billing (API calls, storage, compute time), tiered pricing with overage charges, per-seat licensing with volume discounts, milestone-based project billing, retainer plus hourly overage, and hybrid models that combine multiple pricing dimensions.
The most common scenario we see: a SaaS company starts with simple per-seat pricing, then evolves to usage-based or hybrid pricing as they grow — and discovers their billing tool can't handle the new model.
Integration With Your Revenue Stack
A custom billing system sits at the center of your revenue stack. It connects to your product (for usage data), your CRM (for contract terms), your accounting system (for revenue recognition), and your payment processor (for collections).
This integration eliminates the manual data transfer that causes billing errors, delayed invoices, and revenue recognition issues. When a customer upgrades in your product, the billing system knows immediately.
