Portfolio Systems LLC · Massachusetts

Custom software for property-management operations.

Portfolio Systems answers every tenant call and text in your voice, remembers every unit’s history, triages what tenants can fix themselves, schedules entry within the legal window, and closes every job with a confirmation tenants actually see.

The practice

We build the systems that run your buildings.

Portfolio Systems is a software company for property-management operations. We build the layer between your property-management system and the field — so the work gets done, the tenants stay informed, and nothing falls through.

Maintenance operations

The workflow between a tenant’s “my radiator is cold” and the work order marked done — dispatch, vendors, entry notices, and the confirmation that closes the loop.

The layer on top of Buildium

We integrate with the systems property managers already run — reading and writing tasks, work orders, vendors, and history through a sandbox-verified adapter.

Calls, leasing, and tenant communications

Every inbound line answered, every thread remembered, every legal notice computed to the hour and approved by a human before it goes out.

Custom software, built to fit

When the workflow does not fit a product, we build the product — tailored systems for billing, task management, and the operations your portfolio actually runs.

Flagship software

TenantOps — every call answered, every unit remembered.

TenantOps is our AI operations platform for property managers: it answers every tenant call and text, triages what tenants can fix themselves, schedules entry within the legal window, and closes every job with a confirmation tenants actually see. Built on top of Buildium, verified against a sandbox before it ever touches production.
