CountyOne ®

CountyOne is Avenity’s Revenue Management suite

CountyOne contains three applications: RevenueOne, CashOne, and the CountyOne Taxpayer Portal.  Together, they provide the tax processing and cashiering functionality required by Virginia’s Directors of Finance, Treasurers, and Commissioners of the Revenue.



RevenueOne: Virginia’s Best Revenue Management System

RevenueOne is our revenue management system designed and developed specifically for localities in the Commonwealth of Virginia based on Virginia state code (Title 58.1).   In addition to handling all of the basic tax processing functions, RevenueOne provides many advanced features.  These features include: taxpayer centric approach to eleven Virginia tax types; a common user interface across tax types; integrated workflow; a full collections and enforcement module; support for field and desk audits; a complete history and audit trail; an integrated accounting sub-ledger; a user-friendly custom reporting tool; automated valuation using common data sources (NADA, Vessel Valuation, etc.); configurable payment plans; multi-district support for Real Estate lighting, sewer, and other special-purpose districts.  All of these features are tied together with business-savvy workflow and automating wizards to make RevenueOne the most powerful and easiest-to-use system in Virginia.


CashOne: Our Customizable Cashiering System

CashOne is our cashiering system built to work seamlessly with RevenueOne.  Like RevenueOne, CashOne is designed to integrate with the application infrastructures that are prevalent throughout the Commonwealth. In addition to seamless integration with RevenueOne, CashOne can unite all locality-specific payments including utilities, parking tickets, and miscellaneous fees.  CashOne handles payment processing, balancing, reporting, reconciliation, and deposits.

CountyOne Taxpayer Portal: Taxpayer Self-Service

The CountyOne Taxpayer Portal provides a public user interface for taxpayer self-service.  Taxpayers create and manage their user accounts and passwords and add tax accounts to their user accounts. Taxpayers can then file tax returns, pay taxes, and submit changes such as address changes to CountyOne for immediate processing.  The portal uses responsive design, and can be used on mobile devices as well as standard PC browsers.

CountyOne is different—it is the next generation of tax processing

CountyOne understands the business needs of Finance Directors, Commissioners of the Revenue, and Treasurers, and helps users across offices improve productivity, improve effectiveness, and promote inter-office collaboration to maximize the locality’s revenues.  For example, a change in situs for a vehicle requires one step: tell CountyOne about the change.  CountyOne will then handle the rest of the business process through adjustment, abatement, or supplemental billing, and any other related processing.
