Stripe checkout, Resend emails, and Postgres records in one Next.js repo.
Toolbound Stack gives you a working checkout, signed webhook, buyer delivery email, onboarding email, and purchase records so your first agent session can focus on the product.
Stripe Checkout handles the one-time founder licence purchase flow.
The webhook verifies Stripe signatures before a purchase is recorded.
Resend sends buyer delivery and onboarding emails after payment.
Postgres stores purchases and release metadata for fulfilment.
Payment flow
Stripe covers checkout, signed webhooks, and purchase records.
The stack centres on the moment money changes hands: checkout creation, signed webhook verification, purchase records, delivery state, and buyer email. That gives your agent a working payment path to preserve while it builds the product-specific parts.
Checkout session creation for the one-time product licence.
Webhook verification before a purchase is treated as paid.
Postgres records for purchase and release delivery state.
Setup checks that flag missing payment configuration before launch.
Email flow
Resend sends the buyer emails after Stripe confirms payment.
New SaaS builders often leave emails until the last minute, then discover confirmation, onboarding, and support handoff messages are part of the product. Toolbound keeps that layer in one place so an agent can extend it safely.
Buyer delivery and onboarding templates are included.
Support and internal seller alerts have a documented path.
Agent-added email events can reuse the same provider and conventions.
Secrets stay in local env or deployment secret stores, not pasted into chat.
FAQ
Common questions
Can I take one-time payments?
Yes. Toolbound is currently packaged around a one-time founder licence flow, with Stripe Checkout and webhook verification included.
Can I change it to subscriptions later?
Yes, but that is a product customisation task. The existing billing docs and commercial flow notes give your agent a safer starting point.
Can an agent send emails through Resend?
Yes, if you wire the product event deliberately. The stack documents the email provider and keeps API keys in environment secrets.
