The challenge
The client had a customer-facing booking site and a back-office operating system. Both were useful on their own, but neither understood the other. Bookings drifted from jobs, jobs drifted from invoices, and staff had to close the gaps manually.
The booking flow needed to account for service type, recurring schedules, prices, technician availability, addresses, add-ons, payment choices, and exceptions. It also had to create a traceable result when an external system did not respond as expected.
What ScalarWP built
ScalarWP extended Fluent Forms Pro into an orchestration layer rather than replacing the tools the team already used. The delivery included dynamic and subscription-aware pricing, a real-time technician-calendar view, a signed Simpro webhook receiver, and admin controls for pricing and van records.
When a customer completed a booking, the integration created the matching Simpro job, created either a Stripe subscription or one-off charge, and placed the appointment against the appropriate technician schedule. A self-service backplane gave the operations team control of the data they need day to day without waiting for a developer.
The work also covered the 36-form build, mapping the Simpro tenant, launch migration, and practical runbooks for the client’s team.
The outcome
- Bookings, jobs, payments, and scheduled work now move together through one connected flow.
- The build included a 40-module custom plugin, three admin panels, seven REST endpoints, and an HMAC-signed webhook receiver.
- The client can manage core pricing and operational records directly.
- Failure states are visible and auditable instead of becoming silent data drift.
What ScalarWP delivered
- A custom WordPress integration plugin with 40 modules.
- 36 Fluent Forms booking flows, mapped to the client’s service and pricing rules.
- Dynamic pricing, recurring-service logic, and real-time technician-calendar checks.
- Simpro job creation, Stripe payment orchestration, and signed webhook handling.
- Three admin panels, launch migration, and client runbooks.
Why it mattered
For a field-services business, a booking is the start of a chain of operational commitments. ScalarWP made the WordPress site fit the client’s real process: capture the right details once, create the right records downstream, and give the team a reliable place to intervene when an outside system needs attention.
