Accounts Payable

OBM Shared Services processes invoice payments for more than 25 state agencies. The Accounts Payable team is focused on providing exceptional service to agency and supplier partners. The goal is to stage all invoices for payment within three days of receipt of a valid invoice. A Service Charter between OSS and state agency partners defines the responsibilities and commitments necessary of both partners in order to meet the service level commitments to our customers. Key responsibilities include:

  • Both parties recognize the interdependencies between one another and the need to work together in order to meet or exceed expectations.
  • Both parties understand they cannot be expected to achieve stated performance targets if the other party fails to perform their defined responsibilities.

OBM Shared Services measures success using nine Key Performance Indicators (KPIs). Quality and performance are measured daily and made available to agency partners. The results of these quality measurements are used to improve the OSS service delivery framework, processes, and the overall customer experience.

Agency Partners: OSS Standard Processes

Standardization is a key component of an efficient and effective shared services environment. In order to provide world-class service to State of Ohio suppliers, it is imperative that invoices are processed in a consistent manner. This is even more important when suppliers are providing goods or services to multiple state agencies. OBM Shared Services worked in conjunction with our agency partners to define and thoroughly document our standard processes. These processes are available to our agency partners via an online, searchable repository called "The Source" at:
