Have you Considered RUBS?

Implementing a Ratio Utility Billing System or RUBS billing system is an excellent way to boost net operating income. It's a method of calculating a resident's utility bill based on occupancy, apartment square footage, number of beds, or some combination of factors.

Using RUBS to bill residents for water, gas and/or electricity expenses has several advantages including:

  • Requires no capital investment to get started
  • Enables owners to recoup a large portion of the overall utility expense
  • Can be implemented quickly
  • Immediately improves cash flow.


RUBS vs. Submetering

Many existing apartments have a utility configuration that does not support the installation of submetering equipment. For example, hi-rise apartment complexes and older condominium units can have multiple pipes supplying water to a single unit. This situation makes it cost prohibitive to install water meters to measure consumption because each unit could potentially require more than one water meter.

In these cases, RUBS is an excellent alternative for the owner or condo association to recover appropriate utility costs and increase cash flow at the property.


Learn how to Calculate a RUBS Water Bill

If you'd like to learn how a RUBS water bill is calculated, read this article on our blog. It includes two videos that show you how the calculations are made and what you need to do to implement RUBS.

It also includes a free spreadsheet you can use to calculate a RUBS water/sewer bill for up to ten (10) units.

Measurably Reduce Billing Operations Costs

AmCoBi helps municipal water utilities lower their billing operations costs and expand customer services. Our program will reduce your organization's workload, simplify the billing process, and ensure that your customers receive outstanding support.

In contrast to the operations requirements of providing a safe and reliable water supply, or administering wastewater treatment services, water billing is a function that can effectively be outsourced. The savings are substantial and it frees up staff members to focus on more mission critical duties.

Lower operational costs can also result in more affordable water prices for your customers.

Meeting Customer Payment Expectations

It used to be that providing a return envelope with a payment stub was enough to get customers to send in a paper check. Now, customers want to pay in the mail, with their smartphones, online, on the phone, and sometimes in cash.

Offering multiple payment options can be expensive. It usually requires utilities to deploy multiple systems that they then have to maintain and support. If the online payment options are expensive, customers won't use them and the utility misses out on the efficiencies and cost savings these solutions deliver.

AmCoBi's ePay service is a one-stop-shop. It offers a full range of flexible, electronic payment options via phone, mobile device, or online. ACH payments from a checking or savings account are free! Credit and debit card service fees are some of the lowest available.

As an example, here are some of the ancillary services we provide our clients:

  • Offline, pay-in-cash options
