For founders running multiple products and price tiers through a single Stripe account, where one bad webhook means duplicate charges, missed onboarding, and a Monday morning you can't afford. Built once, monitored continuously, reviewed quarterly.
This tier is built for a specific shape of company. If you're not in the left column yet, the $199 standard tier ships the same core, faster.
event.id with persistent dedupe storage so a Stripe retry never double-fires onboarding, never double-grants seats, never double-charges credits.if (mode === "subscription") sprawl.You're not buying a slide deck. Each phase has a concrete artifact you can point at.
We walk your Stripe dashboard, list every product, every price, every plan. I leave with a written tier map: which products fire which emails, which inboxes get notified, which events you currently care about and which you should. You leave with a fixed scope and start date.
I implement the multi-tier handler in your stack, wire the idempotency store (Postgres / Redis / KV — whichever you already run), set up Resend or your existing email provider with branched templates, and stand up the founder-routing inboxes. PRs land in branches, not main.
Real $1 charges through every product and price, refunded after. You watch each event return 200 in your logs, watch each branched email land in the right inbox, watch each retry get deduped on event.id. We sign off in writing.
Alert channels are live. The 30-day tier-change window starts. The retainer covers on-call. Every 90 days we run an architecture review against the previous quarter's real webhook traffic and produce a written punch-list.
event.idThe standard tier is a single-file webhook with sig verification, one tier mapping, customer + founder email, and a 7-day support window. It's right for a solo founder shipping their first paid plan.
Enterprise is the architecture work that single file points to: a real idempotency store, branched email, multi-inbox routing, subscription lifecycle handling, alerting, and an ongoing relationship. Different problem, different price.
On-call coverage for webhook failures, Stripe API deprecation patches, schema drift on your side (you add a new product, rename a price, split a plan), routine tuning, and quarterly architecture reviews. It does not buy unlimited net-new feature work; large new builds quote separately.
Default: Next.js / Hono / Express on Vercel, Cloudflare Workers, or Render, with Postgres, Redis, or Upstash KV as the idempotency store. Resend for email by default; Postmark and SendGrid swap cleanly. If you're on something exotic (Phoenix, Rails, Django, Go), send the framework and I'll tell you in 30 minutes whether it's a fit.
Stripe will retry an event up to 3 days. Same event.id, same payload, multiple deliveries. Naive handlers double-grant entitlements, double-send onboarding email, double-credit the wrong account. Storing seen event.id values with a TTL is the cheapest correct dedupe; it goes in front of every handler in this build.
Within the first 30 days after launch, changes to the tier map (new product, renamed plan, split tier, new email copy variant, new founder inbox) are included. Past 30 days, those changes are covered under the monthly retainer at normal cadence.
A 90-minute working session every quarter where we read the last quarter's webhook traffic together: failure rates by event type, slow handlers, dead code paths, new products you've shipped since, and whether the dedupe store is sized correctly. You leave with a written punch-list of what to clean up next quarter and what to leave alone.
Standard NDAs and mutual NDAs, yes. Vendor security questionnaires, yes, within reason. SOC2 / HIPAA / PCI-grade audits, no — this is a single-operator engagement and I'd rather tell you that up front than fake my way through a SIG Lite.
The retainer has a 3-month minimum after setup. After that it's month-to-month with 30 days' notice. The codebase is yours; you keep everything I wrote, including the dedupe store schema, the tier map, and the alerting config.
