Company profile

researched Aug 2026

Proper (Proper Technologies, Inc.) is an outsourced property accounting provider that positions itself as a service rather than a software product, describing itself as an external accounting team supported by internally built AI tooling. The company performs bookkeeping and accounting work for property management operators across a range of asset classes, including single-family and multifamily residential, homeowner associations, commercial property (healthcare, industrial, office, retail and storage), co-ops, mobile home communities, short-term rentals and student housing.

Proper's accountants work inside the property management systems its clients already use, with the company listing support for platforms such as AppFolio, Buildium, Entrata, MRI, NetSuite, PropertyWare, QuickBooks Desktop and Online, RealPage, RentManager, Resman, and Yardi Breeze and Voyager, as well as clients operating without dedicated software. Engagements are supported by a dedicated onboarding and support team, and the company states that flexible contracts are offered with no onboarding fees. Proper markets cost reductions of up to 30-50% versus in-house property accounting.

Business model

Proper sells an ongoing outsourced accounting service staffed by its own accountants and augmented with proprietary AI tooling, working within clients' existing property management software rather than requiring migration to a new platform.

Pricing is billed per unit, or per square foot for commercial portfolios, on a month-to-month basis, with flexible contracts and no onboarding fees.

Traction

The company publishes a customer testimonial from Michael Johnson, President of PMI Commonwealth, citing time savings from using the service.
