Payments-first property management software
More doors should mean more than more management fees.
Your rent roll already moves through payments. DoorStax runs the property, and qualifying payment volume can become a second revenue line.

My Earnings
Between Money Out and Reports, there’s a page called Earnings.
It shows what qualifying rent payments earn you. This month, and projected for the year.

Switching
How painful is switching?
DoorStax replaces your current system. Moving over takes three steps.

Import
Export a CSV from your current system, whether it is Buildium, AppFolio, Rent Manager or something else. DoorStax maps the columns, and you review the data before anything is imported.
Open your merchant account
Set up your merchant account in your company’s name, with our help, before you process payments.
Invite your tenants
Each tenant gets an email and adds a bank account or card once.
Timing depends on your portfolio and on your merchant account approval, so we do not quote a number of days.
Try it on your own portfolio.
No card required.
Questions before you switch
Who actually holds the money?
You do. Rent settles directly to your bank from your own Kadima Payments merchant account. DoorStax never holds, pools or transmits your funds.
Who is the merchant of record?
You are. The merchant account is opened with Kadima Payments in your company’s name. DoorStax is a payment technology provider, not the merchant of record.
How does the Earnings page work?
You hold the merchant account, and qualifying rent payment volume can generate earnings for your company. Your Earnings page shows this month’s figure and the projection for the year. Every figure on this page is an illustration, not a quote and not a promise.
Do I have to replace my current system?
Yes. DoorStax replaces your current system rather than adding to it. Moving from Buildium or AppFolio starts with a CSV export, and the migration tool maps your properties, units and tenants.
How quickly can we launch?
Launch is three steps. Start free for 14 days with no card and import your properties, units and tenants from a CSV export. Set up your merchant account in your company’s name, with our help, before you process payments. Then each tenant adds a bank account or card once. Timing depends on your portfolio and on your merchant account approval, so we do not quote a number of days.
What happens to my owners?
Owners are paid from the same ledger as everything else. Payouts and owner statements come from one place, and you review and approve each payout.
Is DoorStax available on mobile?
Yes. The DoorStax mobile app is live on Google Play, with a manager side and a tenant side. On iPhone it is available by invitation only at the moment. Tenants can also pay in the tenant portal.
What does DoorStax cost?
$1 per unit per month, with a $100 monthly minimum. No percentage of rent, no per-building fees and no setup costs. That is the software price; payment processing is priced on your merchant account. Start free for 14 days, no card.
Is any amount guaranteed?
No. What you can generate depends on your portfolio. The estimator on this page is an illustration, not a quote and not a promise.
