Case Study ยท Multi tenant field service SaaS
Purio
Purio is a vertical SaaS platform for water treatment dealers. Each dealer runs their entire operation in Purio: customers, equipment, recurring service, technicians, and billing, fully isolated from every other dealer on the platform.
The Challenge
Where it started.
Water treatment dealers juggle recurring salt and filter deliveries, equipment installs, service calls, and rentals. Most were running on spreadsheets, paper tickets, and generic tools that did not understand their business.
The goal was one platform built for how dealers actually work, that could serve many independent dealers securely from a single codebase.
What We Built
The platform.
Customer and equipment records
Every account, address, and installed system tracked with full service history.
Recurring service and routing
Scheduled deliveries and maintenance organized into technician routes.
Technician workflow
Mobile friendly job views for the people in the field.
Inventory
Stock levels for salt, filters, and parts.
Billing
Recurring and one time invoicing tied to the work performed.
Customer portal
End customers can view their service and account information.
Platform in Action
Real screens from Purio.
Route optimization
Build an optimized route set per location and split it across drivers in one pass.
Work orders
Every job moves from draft to scheduled, en route, completed and invoiced.
Recurring billing
Invoices, recurring charges, point of sale, collections and statements in one place.
Architecture and Security
- Multi tenant data model with strict per dealer isolation enforced at the database layer
- Role based access for owners, office staff, and technicians
- Server side business logic with validated inputs
- Responsive interface built for office and field use
The Outcome
Dealers get one system that understands their industry instead of stitching together generic tools.
The platform is built to onboard new dealers without custom work for each one.
