Customer paid
Stripe confirms the checkout or invoice payment.
Stop paid customers from getting stuck after Stripe checkout
SendPromptly helps small SaaS teams detect when a Stripe payment, checkout, or subscription event succeeded but the customer still did not receive credits, access, or the correct app state.
The support fire you want to avoid
A customer pays via Stripe. Your app processes the webhook. The customer still has no access and no credits. Three hours later, a support ticket arrives. You spend an hour tracing logs, checking queue workers, and wondering if it is safe to run anything again.
⚠️
App did not update
Credits, access, or subscription state never changed.
📩
Support ticket arrives
Paid customer reports a broken experience.
🔍
Manual investigation
Founder or engineer traces logs, checks queues, and wonders what is safe to run.
The recovery workflow
SendPromptly tracks receipt and result separately. If the result is missing or failed, an incident opens automatically — so your team can repair it without guessing.
1
Stripe sends event
Your app receives and verifies the Stripe webhook.
2
App reports receipt
One API call tells SendPromptly the event was accepted.
3
App applies effect
Credits, access, or subscription state is updated.
4
App reports result
Success or failure is confirmed with one API call.
5
Incident + replay
Missing or failed result opens an incident. Reprocess sends a signed callback to your repair endpoint.
What SendPromptly catches
These are the specific Stripe failure types SendPromptly is built to detect before your customers report them.
Missing credits after invoice.paid
Stripe confirmed the payment. Your app did not add the credits. Common in usage-credit SaaS, AI credit products, and prepaid API billing.
Missing access after checkout.session.completed
The customer paid, but the app did not unlock the feature, plan, workspace, or account. The most common post-payment support failure.
Subscription-state drift
Stripe and your local app state no longer agree after a renewal, plan change, or recovered failed payment.
Silent background job failures
Your webhook returned 200. The queued job ran. But the business effect never completed. SendPromptly catches this because it waits for your result, not just your receipt.
Why Stripe logs are not enough
Stripe shows delivery. SendPromptly tracks fulfillment. These are not the same thing.
Stripe confirms delivery, not fulfillment
Stripe logs show that your endpoint returned 200. They do not show whether your app granted access, added credits, or updated subscription state.
A 200 response means receipt, not effect
Best practice is to accept Stripe events quickly and process asynchronously. That means the effect happens after the 200 — outside Stripe's view entirely.
Your app owns the business effect
Stripe owns the payment. You own what happens after. SendPromptly instruments that gap and gives your team visibility and a safe way to repair it.
Built for small SaaS teams
SendPromptly is designed for 1–3 engineer teams with custom Stripe fulfillment logic who cannot afford to build internal incident tooling from scratch.

What teams say
Small SaaS teams using SendPromptly to protect paid customer experiences.
Alicia Park
Founder, CometCart
We stopped manually tracing Stripe logs every time a customer reported missing credits. SendPromptly opens the incident for us.
Marcus Young
CTO, FitLedger
The integration was two HTTP calls in our webhook handler. We caught our first real incident within the week.
Priya Iyer
Lead Engineer, RelayOps
Reprocess is the piece we were missing. Safe replay with a signed callback we control.
Start with one Stripe flow
Instrument the payment path that already causes support pain. Add two API calls and get incident detection in an afternoon.
