Proper

Proper (proper.ai) is an AI-powered, full-service property-management accounting and bookkeeping provider serving property managers, asset managers, and real estate developers. Rather than shipping software, Proper delivers a trained accounting team supported by automation to handle accounts payable, accounts receivable, bank reconciliations, month-end close, and financial reporting, integrating with existing property-management systems such as AppFolio, Buildium, and RentManager. Founded in the property-management space in 2017, the company is backed by QED Investors, Redpoint Ventures, MetaProp, Expa, and Bling Capital. As of this enrichment pass Proper exposes no public API, developer portal, SDK, or machine-readable developer surface; this profile is maintained as a company record.

Proper is profiled on the APIs.io network. Tagged areas include Company, PropTech, Property Management, Accounting, and Bookkeeping.

Proper’s developer surface includes engineering blog and 3 more developer resources.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/proper: open an issue to ask a question, or submit a pull request to add artifacts.
