As a certified Rent Manager partner, SimpleSUB makes water submetering simple: clamp-on submeters bill each unit for the water it actually used, and the charges push straight to your Rent Manager tenant ledgers in one click.
One water bill. No idea where it went.
If your property runs on a master meter, you know exactly what last month's water bill was. You don't know how much of it was Unit 101 versus Unit 102, or which unit has a toilet that's been running for three days.
So the owner either eats the bill as an operating expense or splits it by a formula tenants don't trust. Either way, the people using the most water have no reason to use less.
You can see that the property used water. You can't see where.
From the pipe to the tenant ledger in three steps.
SimpleSUB measures each unit and builds the bills. One click posts them to Rent Manager. Nobody retypes a charge.
Submeter clamps on in 5 minutes
Two zip-ties on the outside of the existing pipe. No cutting, no water shutoff, no plumber. Press the button and it connects over cellular on its own, so there's no Wi-Fi, gateway or IT work.
Split your bill by unit-level usage
Enter the property's water bill. SimpleSUB splits it across units by the water each one actually used, from automated daily reads that are 100% within ±5%.
Tenant charges via
Review the bills and push them to Rent Manager in one click. Each tenant's water charge posts directly to their ledger next to rent, and they pay it the way they already pay you.
Set it up once. Push charges every month.
No third-party billing service, no middleman, no spreadsheet in the middle. SimpleSUB does the measuring and the math. Water charges post straight to your Rent Manager tenant ledgers.
Match units via Rent Manager API
