I looked into it or a similar company a while ago. It was being used by a large property management firm. It is a third party verifier. It is also offered by some property management software.
Payscore is an automated income verification service. It requires the applicants to log into their bank accounts through its service, and then it scrapes data from their accounts. The service aims to save time in verifying income.
The same information can be gotten by requiring several months of bank statements and pay stubs, and correlating the deposit dates with the payroll dates. You can also look at the YTD information on the pay stub to see if there was a significant gap in income.
If you require that an applicant use Payscore, you need to disclose it before the tenant pays an application fee or refund it if an applicant refuses. A bank may not cover an applicant's losses if they have shared their account login information. I don't want an applicant looking at me for recovery if something goes wrong. You also cannot be certain that a service will not scrape other, more sensitive data.
If it is the company that I remember, it is a small and still young startup. It has an impressive website. From the small number of employees, it was obvious that they could not have a deep cybersecurity team. If they do something deep, it is likely outsourced to yet another underlying service. After having the unpleasant experience of one of the underlying companies in a fintech service going kapooey some time ago, I'm cautious about exposing myself and any clients or tenants to the latest shiny fintech object.
If you yourself would share your own bank account login credentials with this service, then you have standing to use it with your applicants. What's good for the goose, and all. --181.214.xxx.xxx
