ProofUp is an AI tenant screening platform for property managers. It confirms income through bank and payroll links, matches IDs to live selfies, and flags forged files in under three minutes.
About ProofUp
What Is ProofUp
ProofUp is tenant screening software built for rental applicant screening, aimed at operators who are tired of trusting paper. The applicant gets a link, connects a bank or payroll account through Plaid, photographs a government ID and takes a live selfie. Documents are optional, and every file that does arrive gets read twice: once for how the file was built, once for what the page actually says.
The product exists because a forged pay stub now looks exactly like a real one. Modern PDF tools produce documents with correct year to date math and real employer names, and a leasing agent staring at a printout has no way to tell the difference. ProofUp moves the number that matters out of the document and into the account, then reports what it found with the evidence attached.
The limits are worth stating up front. ProofUp is built for portfolios over 500 units, prices by quote rather than a public rate card, and publishes no API documentation. Applications carrying a fraud signal or a name mismatch land in a review queue, so a person still has to open them.
Getting Started
- Request a demo from the ProofUp site. Sales runs a live screening with you, covering the Plaid connection, the ID match and a document scan.
- Connect your property management system and set which verdicts your team can approve without review.
- Send an applicant the screening link. They open it in any mobile browser, with no app and no account.
- Read the verdict in the dashboard. Every flag names the document, the reason and the attempt that triggered it.

Best for
The users, tasks, and scenarios where this tool fits best.
Users
- Mid-market and regional property managers
- Leasing teams with heavy application volume
- Landlords renting to gig workers and self-employed applicants
Tasks
- Confirming stated income
- Catching forged pay stubs and edited bank statements
- Matching an applicant to their ID
- Documenting an approval or an override
Scenarios
- An applicant submits a flawless pay stub that doesn't match the deposits in their account. The income check fails before anyone signs a lease.
- Peak leasing season brings 200 applications in a week. The team works from one dashboard instead of chasing callbacks.
- A freelancer has no traditional pay stubs. The payroll connection covers gig income, and uploaded files still get graded by source.
Key features
Income Verification at the Source
ProofUp connects to the applicant's bank or payroll account through Plaid and pulls income from the deposits themselves. There's no document in that path, which removes the most common place for a forgery to enter the process. Gig and non-traditional income is covered by the payroll integration, a gap that document-only screening leaves open.
Document Fraud Detection
Every uploaded file is read at the byte level. The structural pass looks for hidden data layers, edits made after the file was created, metadata that doesn't match the claimed bank or payroll provider, and signatures from known fake document generators. This is forged pay stub detection at the file level, not at the picture level. A second AI pass reads the page content and checks employer details, pay period continuity and figures that contradict the deposits underneath them. A forgery clean enough to survive one pass usually fails the other.
Identity Verification With a Live Selfie
The applicant photographs both sides of a government issued ID, then takes a live selfie, and Plaid compares the two in real time. A name and Social Security number on paper say nothing about who is standing at the showing. This check closes that gap and flags mismatched or synthetic identities before the application moves forward.
Five Verdicts Instead of One Score
Most screening reports reduce an application to a single number. ProofUp returns one of five verdicts: passes requirements, passes with caution, non-recurring income, needs review, or fails requirements. Two of them pass at medium risk, which lets a leasing team approve an applicant while flagging the file for a later sample review.
Evidence Quality Grading
The same income figure can reach you four ways, and they aren't equally trustworthy. ProofUp grades each one: a bank or payroll connection is strongest, a PDF downloaded from the payroll portal is strong, a print to PDF or re-saved file raises caution, and a scan or phone photo raises caution too. The report states which one you got, per document.
Audit Trail and Plain Language Flags
When an application fails, the dashboard shows which document was flagged, why it failed and which attempt triggered it. Each record keeps the verification method and the source behind it, and any override by a leasing agent is logged as well. That matters when a decision gets questioned months later, by an owner or by a lawyer.
Pros and cons
Pros
- Income figures come from the applicant's account, not from a file they control.
- Two independent document passes catch forgeries that a visual inspection or a single AI check would miss.
- Every verdict states its reason and the next step, so a leasing agent doesn't need to interpret a score.
- Applicants finish in any mobile browser, which cuts the drop-off that app installs create.
- Audit trail covers approvals and overrides, which helps in a dispute or a fair housing review.
Cons
- Pricing isn't published. You have to book a demo and negotiate a quote before you know the cost per application.
- No public API docs, so connecting it to a custom stack means asking sales for details.
- The strongest evidence depends on Plaid. Applicants who refuse to link an account fall back to documents, and the report says so.
- Needs review verdicts still require a human decision, so the tool reduces manual work rather than removing it.
- Built for portfolios over 500 units. A landlord with four doors will pay for checks they don't need.
Frequently asked questions
ProofUp screens rental applicants before a lease is signed. It confirms income, verifies identity and checks uploaded documents for tampering, then returns a verdict with the evidence behind it. Property managers use it in place of the income review they used to do by eye.
