How it works

Every inbound document.
Read, extracted, synced.

01
Any source, any format

Scanner. Inbox. Fax. Portal download. Vendor invoices, contractor COIs, compliance notices, inspection reports — Mailroom catches everything the moment it lands.

02
Data extracted, no re-entry

Vendor name, invoice amount, COI expiration dates, policy numbers, violation codes — pulled automatically. Handwritten or typed. Every field your team would otherwise enter manually.

03
Synced, filed, and forwarded.

Data posts to Buildium, AppFolio, or your accounting tools. Vendor invoices land ready to approve. COI expirations hit your calendar. Violation notices become tracked tasks. You get your evening back.

Get back 40+ hours of admin every month
and stop worrying about compliance gaps.

If you're doing this yourself, it's stealing your nights and weekends.
If you're paying someone else to do it, it's costing you $3,000–$5,000/month in salary.
Either way, it's unsustainable.

What people are saying

Other property managers got
their hours back. So can you.

★★★★★

"I was maxed out at 120 units doing everything myself. Mailroom freed up 15 hours a week — I've added 80 more units in six months without hiring anyone."

DK
David Kim
Owner · Metro Property Services
★★★★★

"Our office manager was spending 10+ hours a week just entering vendor invoices into Buildium. Mailroom cut that to zero. We redeployed her to tenant retention instead."

SC
Sarah Chen
Portfolio Manager · Crestview Property Management (450 units)
★★★★★

"We nearly got hit with a $15K fine because a housing violation notice sat in a pile for three weeks. Now every notice is flagged the day it arrives. That alone pays for Mailroom."

FAQ

The questions you're
probably thinking right now.

What types of documents does Mailroom handle — and how accurate is extraction?
Mailroom handles vendor invoices, Certificates of Insurance (COIs), housing violation notices, inspection reports, lease documents, and permit paperwork — whether they arrive typed, printed, scanned, photographed, or handwritten. Extraction is 99% accurate across document types. Every field shows a confidence score, and anything uncertain is automatically flagged for one-click human review — so nothing gets posted to your system with bad data. Every extraction decision is logged with a full chain of custody, so you always know what was read, when, and with what confidence.
What tools does Mailroom integrate with?
Mailroom integrates with 100+ tools — including Buildium, AppFolio, QuickBooks, Xero, Google Workspace, and more. If you don't see your tool on the list, you can request it. Our team is always adding new integrations, and customer requests go straight to the top of the queue.
What if Mailroom extracts something wrong?
Mailroom flags low-confidence extractions for one-click human review before syncing to your PM system. You stay in control, and accuracy improves over time as it learns your vendors and document formats.
How long does setup take?
About 10 minutes. Connect your property email inbox, point your scanner to a Mailroom address, and link your Buildium or AppFolio account. Tomorrow's documents start handling themselves.
Do contractors need to change how they send COIs?
No. Vendors and contractors keep sending invoices, COIs, and documents the same way — email, fax, mail, portal upload. Mailroom catches everything automatically.
Is Mailroom right for smaller portfolios?
Yes. Even if you're managing 20–30 units, vendor invoices still need to be entered, COIs still expire, and compliance notices still land in your inbox. The difference is that at a smaller portfolio size, you're the one doing all of it personally — which makes Mailroom more valuable, not less. Many of our users started with a small portfolio and found that eliminating the admin burden was exactly what let them grow.
Is my document data safe?
Documents are encrypted in transit and at rest. Role-based access controls mean only the right people see the right documents. Full audit log on every action. We're built toward SOC 2 Type II.
Where do my documents go — and who controls that?
You do. Mailroom stores every document and lets you set rules for how they're organized — by property, vendor, document type, or any folder structure you already use. Documents land exactly where you want them, automatically.
Can I customize how Mailroom handles my documents?
Yes. You set the rules — which documents go where, what triggers an alert, and what gets flagged for review. Mailroom follows your workflow, not the other way around.
Your back office, automated.

Tomorrow's documents
handle themselves.
