Automotive transaction infrastructure

The transaction layer for automotive service.

JackRelay turns service requests into canonical offerings, pricing, quotes, availability, and appointments — one connection layer between repair shops and the software and AI agents that send them customers.

See how it works For repair shops
  1. Request Front brake noise 2019 Honda Accord · customer or AI agent
  2. Service intent Brake pad replacement resolved · canonical service
  3. Shop & offering Harbor Auto · Broad St. front brake pads · 75 min
  4. Price Starting at $189 shop-set price policy
  5. Availability Tomorrow · 10:30 AM platform-managed slots
  6. Appointment Confirmed · 10:30 AM Harbor Auto notified

One canonical path — from a request in any language to a confirmed appointment.

Every new booking surface shouldn’t mean rebuilding how your shop runs.

Customers, apps, and AI assistants all ask for service differently. JackRelay gives them one canonical vocabulary — and executes each transaction the way your shop actually operates.

01Service intent

A request arrives in natural language — from a customer, a booking surface, or an AI agent. JackRelay resolves it into a canonical service intent, without pretending to diagnose uncertain symptoms.

02Shop

The intent is matched to shops and locations that offer the service, serve the customer’s area, and can actually work on that vehicle.

03Offering

Every shop publishes its canonical offering: the service, its duration, and the vehicles it fits — versioned and shared across every demand source.

04Price & quote

Prices stay canonical — exact, starting-at, range, or quote-required. When a job needs eyes on it first, JackRelay opens a quote request instead of guessing.

05Availability

Slots come from authoritative sources only: platform-managed capacity or verified vendor availability. An empty calendar is never sold as open time.

06Appointment

The booking lands in the shop’s real workflow — direct confirmation where capacity exists, or a request the shop accepts. A request is never falsely confirmed.

For repair shops

Your shop. Your terms. One canonical layer.

The repair shop is the customer. Publish once, and every surface that sends you customers transacts against the same services, prices, and availability.

  • Publish services once. Canonical names, prices, and durations your whole business shares — not per-marketplace re-entry.
  • Bookings and quote requests in one place. Direct confirmation where capacity exists, request confirmation where you want it.
  • You keep control of scheduling. Hours, buffers, capacity, and quote rules stay yours — the transaction layer respects them.
  • Connect shop software when it’s real. Vendor connections activate with official contracts — and you keep running natively until then.

Native JackRelay workflow

Runs natively. No third-party software required.

A shop can go from empty to fully bookable on JackRelay alone. Services, pricing, durations, hours, scheduling rules, and capacity are first-class platform configuration — not a fallback mode.

Native bookings are confirmed against capacity enforced by the database itself: concurrent requests cannot oversell a slot, and a crash can’t silently lose one.

Connection architecture

Provider-neutral by design.

JackRelay routes every transaction through one canonical layer — and executes it wherever your shop actually operates.

JackRelay canonical layer

Native platform

active

Services, pricing, hours, and capacity configured directly in JackRelay. Implemented and tested against real PostgreSQL.

Request confirmation

active

Bookings arrive as requests your shop accepts or declines. A request is never presented as confirmed.

Vendor connection

requires official contract

Connect shop-management software once an official, verified integration exists. Until then, nothing is advertised as connected.

Redirect

provider-dependent

Approved external booking links where a provider contract allows — validated, never blind.

Vendor paths activate only with official contracts and a verified sandbox end-to-end. Provider state is product data — never a marketing claim.

Developers

One canonical interface. Every execution path behind it.

Build against service intents, offerings, quotes, and appointments — never against vendor tenant IDs, credentials, or payload formats. Those stay behind the router.

BookMyJack

The shop-facing application of JackRelay.

BookMyJack is where shops run on the platform: configure services and scheduling, review booking and quote requests, and follow every appointment through its state. It is a product surface of JackRelay — the same canonical data, in the shop’s hands.

  • Configure services, pricing, and durations
  • Accept or decline booking requests
  • Answer quote requests
  • Track appointments and connection health

Security

Boundaries that stay boundaries.

JackRelay is built as transaction infrastructure: authorization, isolation, and conservative semantics are part of the product, not an add-on.

Shop-scoped authorization
Signed shop principals with membership-checked scope; appointment reads require the shop principal or an appointment-scoped capability.
Tenant isolation
A shop cannot read or touch another shop’s connections, credentials, appointments, quotes, or capacity — proven by multi-tenant tests.
Credentials in a vault
API keys and tokens are encrypted at rest behind a vault boundary; responses and logs never echo secrets.
Canonical identifiers only
Agents see shop, offering, quote, and appointment IDs. Vendor tenant IDs and credentials never leave the platform.
Conservative booking semantics
Requests are never falsely confirmed. Ambiguous writes go to reconciliation — never to silent success.
Capacity enforced by the database
Native slots are reserved atomically; competing processes cannot oversell a shop, and crashes can’t silently consume capacity.

Production hardening — identity provider, managed secrets, rate limits, and audit events — is in progress and will be stated here when it ships.

Put your shop on the transaction layer.

Configure once, publish once. Your services, prices, and availability become one canonical interface for every surface that sends you customers.
