Customer paid
Stripe or Shopify confirms the payment or order.
Payment succeeded. Customer still has no access. Now what?
SendPromptly catches paid-but-not-applied incidents across Stripe and Shopify — missing access, credits, or app state — and gives your team a safe way to fix them fast. No more 11 PM log traces. No more risky manual database edits.
The support fire you want to avoid
A customer pays. 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 hours later.
Manual investigation

How SendPromptly works
SendPromptly monitors whether the business effect your customer paid for actually happened — and opens an incident automatically when it did not.
1
Payment event fires
Your app receives and verifies a Stripe or Shopify webhook.
2
App accepts the work
One signal tells SendPromptly the event was durably accepted.
3
App applies effect
Credits, access, or subscription state is updated.
4
Outcome reported
Success or failure confirmed. Missing or failed — incident opens automatically.
5
Safe repair
Your team clicks Reprocess. A signed callback triggers your idempotent repair endpoint.
What SendPromptly catches
The paid-but-not-applied failures that create urgent support work — caught before your customers report them.
Missing access after checkout
Customer paid and Stripe confirmed the checkout. Your app never unlocked the feature, plan, or workspace. The most common post-payment support failure for SaaS teams.
Missing credits after invoice payment
Stripe confirmed the payment. Your app did not add the credits. Common in usage-credit SaaS, AI credit products, and prepaid API billing.
Silent background job failures
Your webhook returned 200 and the queue accepted the job — but the business effect never completed. SendPromptly catches this because it waits for the outcome, not just the receipt.
Shopify orders paid but never fulfilled in your app
An orders/paid webhook came in but your app never applied the business effect. SendPromptly monitors Shopify flows the same way it monitors Stripe — same incident model, same repair workflow.
Why payment logs are not enough
Stripe and Shopify show delivery. SendPromptly tracks fulfillment. These are not the same thing.
Delivery ≠ fulfillment
Payment logs show that your endpoint returned 200. They do not show whether your app granted access, added credits, or updated subscription state.
A 200 means receipt, not effect
Best practice is to accept payment events quickly and process asynchronously. That means the effect happens after the 200 — outside the payment provider's view entirely.
Your app owns the business effect
Stripe and Shopify own the payment. You own what happens after. SendPromptly instruments that gap and gives your team visibility and a safe way to repair it.
Security, privacy, and operational foundation
SendPromptly is designed to handle payment incident data safely — without becoming a liability.
🔐 Metadata-first storage
By default SendPromptly stores only identifiers — event type, effect type, your internal reference, and status. Full payload snapshots are opt-in and encrypted at rest. You control what we hold.
🔏 Signed repair callbacks
Every reprocess callback is HMAC-SHA256 signed with a project-scoped secret. Your repair endpoint verifies the signature and timestamp before acting. Replayed or stale callbacks are rejected automatically.
🛡️ Idempotency by design
SendPromptly deduplicates on provider event ID so duplicate webhooks never create duplicate incidents. Reprocess assigns a unique replay_id so your repair handler can run safely more than once.
🔑 Project-scoped API keys
API keys are scoped to a single project. The dashboard shows the plaintext key once; only the hash is stored. Rotate keys without downtime by generating a new key before revoking the old one.
📋 Full audit trail
Every state transition, reprocess attempt, and operator action is logged with actor and timestamp. The audit log is retained after incident resolution — useful for postmortems and customer support.
⏱️ Configurable data retention
Event metadata is retained for 12 months. Encrypted payload snapshots, if enabled, are purged after 30 days by default. You are not accumulating raw payment data you do not need.
Built for small SaaS teams
Designed for 1–3 engineer teams with custom Stripe or Shopify fulfillment logic who cannot afford to build internal incident tooling from scratch. More payment providers are coming.

What teams say
Small SaaS teams using SendPromptly to protect paid customer experiences.
We had three incidents in our first month where Stripe confirmed payment but our credit grant job failed silently. Before SendPromptly we found out days later through a support ticket. Now we get an email within 30 minutes and fix the customer before they notice anything is wrong.
Days-later support tickets → 30-minute repair
Alicia Park
Founder, CometCart
Two HTTP calls in our existing Stripe handler. Took an afternoon to wire up. We caught our first real incident — a webhook timeout that silently left a paying user locked out after upgrading — within the first week of going live.
First silent incident caught within one week
Marcus Young
CTO, FitLedger
The thing I didn't expect to value was the audit trail. When a customer reports a billing issue now, I pull up the incident, see every attempt, and show them exactly what happened and when. Support resolution went from an hour of log tracing to under five minutes.
Support resolution: 60 min of log tracing → under 5
