Field-services back-office
SimpleAppBuilders platform configured and deployed for a 12-person HVAC operation. Jobs, dispatch, and invoicing in one place.
A 12-person HVAC outfit was running their day on three different tools — a spreadsheet for jobs, a separate SMS thread for dispatch, and QuickBooks for invoicing — with techs typing the same job number into all three. Errors were inevitable; closing out a job took twenty minutes of paperwork.
We stood up the SimpleAppBuilders multi-tenant platform configured for field services: a job board with status transitions, dispatch view for the office, mobile-friendly tech view for on-site updates, and an invoice generator that pulled directly from completed jobs. Deployed on AWS with Terraform-defined infrastructure and SSO through their existing Google Workspace.
Average job close-out dropped from twenty minutes to under three. Dispatch errors fell to roughly one a month. The office had a real-time view of where each tech was and what they were working on for the first time. Customer added a second crew without adding a back-office hire.
Stack & notes.

Notes
The platform's multi-tenant foundation means a second crew or a second business location is a configuration change, not a rebuild. The SAB team owns the deployment and the maintenance — Jayler Pitch holds the relationship.
