How to Invoice a Property Management Company
A property management company needs one invoice per property or unit, referencing their work order or PO number, itemized task by task with photos, with damage-related items separated from routine maintenance so costs can be allocated between owner and tenant deposit. Have a W-9 and certificate of insurance on file before the first job, invoice the day work is complete, and expect net 15–30 terms rather than payment on the day.
Property managers are the best B2B customer a trade can have
Steady work, no marketing, and a manager with dozens of properties to send your way. The trade-off is that they pay on their process, not yours — and almost every payment delay in this relationship is really just a paperwork problem you can head off ahead of time.
Get these on file before the first job
- W-9 — you cannot be set up as a vendor without it
- Certificate of insurance — usually naming them as additional insured
- Trade license where the work requires it
- Your W-9 email on file with their accounting contact
A vendor missing any of these usually doesn’t get paid slowly — they don’t get paid at all until it’s fixed.
One invoice per property, always
They code costs to properties and owners, so a combined invoice covering four units is just work you’ve handed back to them. And it lands in the pile of things to deal with later.
Reference their number, not just yours
Put their work order, PO, or job number at the top of the invoice, not just your own. That’s how it gets matched to an approval — an unmatched invoice can sit indefinitely without anyone ever consciously deciding to delay it.
Separate damage from routine
Routine maintenance is an owner expense. Damage may be a tenant deposit deduction. Two labeled sections with separate subtotals let the manager allocate it in seconds, and an invoice that’s easy to allocate tends to get approved the same day it arrives.
Invoice the day you finish
The work is fresh, the manager still remembers authorizing it, and there’s nothing to verify. Wait a week and your invoice is competing with month-end, and now someone has to reconstruct what happened.
Photos attached, not on request
Every item that could get questioned should already have a photo attached to the invoice. “I’ll send photos if you need them” just adds a round trip, and every round trip costs you a payment cycle.
Chase gently, and ask the manager first
Late payment is almost always an unclicked approval, not a refusal. One polite message to the property manager fixes most of it. Go straight to accounting instead and you might solve the one invoice — but it can cost you the next twelve jobs.
Frequently asked questions
Why can't I send one invoice for several properties?
Because property managers code every cost to a specific property and often to a specific owner's account. A combined invoice makes them do the splitting themselves, which is exactly the work that pushes your invoice to the bottom of the pile.
What paperwork do I need before the first job?
A W-9 and a certificate of insurance naming them as additional insured, plus your license where required. A vendor missing any of these can't be paid at all in most systems, no matter how good the work was.
How fast do property managers actually pay?
Net 15 to net 30 is typical, and the clock starts when the invoice is approved, not when you sent it. Approval is fast when the invoice is itemized, referenced to a work order, and arrives while the job is fresh — which is entirely within your control.
Should I chase a late invoice with the property manager or the accounting department?
Ask the property manager first, once, politely — usually it's an approval that never got clicked, not a refusal. Going straight to accounting over a manager's head is how a good recurring relationship quietly stops sending work.
