Signs you need this now.
Off-the-shelf subscription tools break down fast once you need custom plan logic, usage-based tiers, or proration rules that don't match the billing platform's assumptions. Most revenue loss in subscription businesses isn't from churn decisions — it's from failed card payments and broken renewal logic that nobody is watching closely enough to catch.
Failed card payments quietly churn customers who never meant to cancel
A card expires or a bank declines a renewal, and the subscription just silently lapses with no retry or recovery flow. The customer finds out weeks later when they try to log in and can't.
Proration math is wrong on plan upgrades and downgrades
A mid-cycle plan change either overcharges or undercharges because the proration logic wasn't built to handle it correctly, and support has to manually issue credits. It happens often enough that finance stopped trusting the numbers in the billing dashboard.
The billing platform can't handle a plan structure that isn't standard tiers
Usage-based pricing, seat-based billing with mid-cycle seat changes, or hybrid plans don't fit cleanly into the off-the-shelf subscription tool's model. Workarounds pile up until the billing system is more fragile than the product it's charging for.
What you get.
Custom plan and proration engine
Billing logic built around your actual pricing model — tiers, usage, seats, or hybrids — with proration calculated correctly for upgrades, downgrades, and mid-cycle changes.
Automated dunning and payment recovery
A retry sequence with configurable timing and customer notifications that recovers failed renewal payments before they turn into involuntary churn.
Full subscription lifecycle management
Trials, upgrades, downgrades, pauses, cancellations, and reactivations all handled with consistent billing state, so support isn't manually patching accounts.
Invoice generation and tax-ready line items
Invoices generated automatically per billing cycle with line-item detail suitable for accounting and tax reporting, not just a lump-sum charge.
Revenue and churn reporting
MRR, churn, and expansion revenue calculated from actual subscription events instead of estimated from a spreadsheet export.
Webhook-driven sync to your app and CRM
Subscription status changes propagate automatically to your product access logic and CRM, so a canceled plan actually revokes access without a manual step.
Four steps, no mystery.
Quick scoping call
A short call (or async over WhatsApp) to understand what you're working with and what "done" actually looks like for you.
Fixed scope, no surprises
A clear written plan of what's included and how long it takes, before any work starts.
The actual work
Progress you can see, not a black box. You get updates as milestones land, not just a status report at the end.

Frequently asked.
Both are possible — this can extend Stripe Billing with custom logic Stripe doesn't natively support, or be built as an independent billing engine if your pricing model needs more control than any off-the-shelf platform gives you.
