Booking flow reliability pilot
Stop double-bookings before adding more integrations.
SignalMend repairs one broken booking path or builds one bounded vertical slice around a clear source of availability, atomic reservation, explicit failure states, and repeatable notification evidence.
$149 booking-path repair · $399 bounded booking slice · starts after funding and access
Good first-pilot signals
- Two visitors can reserve the same slot during simultaneous requests.
- The calendar shows availability that the booking handler cannot safely commit.
- The interface says booked before storage or notification handoff succeeds.
- Retries create duplicate bookings, emails, or follow-up actions.
Included
- One booking form and one agreed availability source
- Server-side validation and atomic slot reservation
- One idempotent confirmation-notification path
- Concurrent, stale-slot, invalid-input, and retry checks
- Deployment notes, rollback path, and concise handoff
Not included
- A complete multi-provider booking marketplace or open-ended rebuild
- Calendar, payment, CRM, or SMS integrations outside the written milestone
- Guaranteed inbox placement or delivery timing across third-party mail providers
- Unapproved production data, credential sharing, or regulated-data work
- Changes before scope, funding, access, backup, and acceptance gates
Acceptance
A repair is complete only when the evidence is repeatable.
- 01A valid request for an open slot creates exactly one booking and a visible receipt.
- 02Two simultaneous requests for the same slot produce one accepted booking and one explicit unavailable result.
- 03Repeating the agreed request does not create a duplicate booking or notification.
- 04Invalid or stale-slot requests fail visibly without partial records.
- 05The agreed notification provider accepts the correct template and returns recorded receipt evidence; inbox placement is not claimed.
Relevant evidence
Live booking and operations system
Slovak Together is a live self-initiated booking implementation with public availability, duplicate protection, an idempotent fail-closed notification outbox, and operational health monitoring. It is implementation evidence, not client work, a multilingual-mail claim, or a commercial result.
Fixed scope before work begins
Lock one booking path before adding calendars and payments.
Send the current URL or stack, what a visitor does, what happens now, and the exact accepted result. You will get a written fit decision, exclusions, access list, fixed price, and acceptance checks before any production change.
