Stripe SaaS billing source kits for Node apps
Buy six Stripe billing source kits as one Node SaaS bundle.
The Stripe SaaS Billing Toolkit bundle packages the live AgentLaunchOps source kits for team seats, usage alerts, MRR reporting, invoice tax metadata, cancel-save flows, and metered API access into one $79 Gumroad checkout.
Included Paid Kits
The bundle checkout is the fastest path when you need more than two workflows. Individual Gumroad checkouts stay available below when you only need one focused source kit.
$29
Stripe Team Seat Kit
Map subscription quantity to team seat limits, signed invites, active-subscription checks, and webhook syncing.
$29
Stripe Usage Alerts Kit
Track usage thresholds, queue warning events, summarize billing limits, and sync usage invoices from Stripe.
$29
Stripe MRR Analytics Kit
Calculate MRR, ARR, churn, paid invoices, refunds, and subscription revenue snapshots from webhook events.
$29
Stripe Invoice Tax Kit
Collect invoice metadata and tax IDs, verify invoice webhooks, sync invoice state, and render receipt data.
$29
Stripe Cancel Save Kit
Capture cancellation reasons, present save offers, confirm cancellations, and report save-rate analytics.

Metered API Launch Kit
Issue API keys, enforce monthly quotas, log usage, expose protected routes, and connect access to checkout events.
Adapt-It-Yourself Source
The bundle delivers compact source packages for developers who already have an app, database plan, and Stripe account. The code is meant to be read, tested, and adapted into your billing layer.
npm run verify:manifest
npm test
npm run smoke:buyer
The delivered source kits include setup notes, source files, tests, buyer smoke checks, and checksum manifests.
Choosing A Kit
Seats
Choose the team-seat kit when your pricing is tied to users, invites, and subscription quantity.
Usage
Choose usage alerts or metered API when your product needs quota warnings, usage logs, or key-based access.
Revenue Ops
Choose MRR analytics, invoice tax, or cancel-save when your billing workflow needs reporting or retention helpers.
Billing Workflow Matrix
| Workflow | Best Fit | Included Focus | Checkout |
|---|---|---|---|
| Team seats | B2B SaaS plans where subscription quantity controls user access. | Seat limits, signed invites, active-subscription checks, and webhook syncing. | Stripe Team Seat Kit |
| Usage warnings | Apps that need quota warnings before users hit billing or plan limits. | Threshold rules, alert queues, usage summaries, and invoice event sync. | Stripe Usage Alerts Kit |
| Revenue reporting | Small teams that need a source-level MRR snapshot without wiring a full analytics stack. | MRR, ARR, churn, paid invoice, refund, and subscription revenue calculations. | Stripe MRR Analytics Kit |
| Invoice tax metadata | SaaS apps that need invoice-ready checkout data and receipt rendering. | Tax ID collection, invoice webhooks, invoice state sync, and escaped receipt HTML. | Stripe Invoice Tax Kit |
| Cancel-save flow | Subscription products that want a structured retention step before cancellation. | Reason capture, save offers, cancellation confirmation, and save-rate analytics. | Stripe Cancel Save Kit |
| Metered API access | API products that sell access by key, quota, and usage history. | API key issuance, monthly quotas, protected routes, usage logs, and checkout hooks. | Metered API Launch Kit |
The table is a buying guide, not a hosted integration promise: the bundle and individual checkouts deliver source code to adapt into your own app.
Bundle Checkout
Buy the complete Stripe SaaS Billing Toolkit bundle when you want all six workflows in one purchase, or use the table above to buy a single kit for a narrower integration job.
Questions Before Buying
Are these Stripe billing kits a single hosted service?
No. They are paid source kits for Node developers who want focused reference code, tests, setup notes, and buyer smoke checks to adapt inside their own application.
Which Stripe billing kit should I buy first?
Choose based on the workflow you need now: seats for team billing, usage alerts or metered API for quota-based products, and MRR analytics, invoice tax, or cancel-save for revenue operations.
Can I buy the kits separately?
Yes. The $79 bundle is available when you want all six, and each published kit has its own Gumroad checkout when you only need one Stripe billing workflow.
