# Existing Client > Existing Client means any individual or entity presently availing services or products, or has availed within the past two-years from [Organization Name]. **Term:** Existing Client **Last updated:** 2026-07-29 ## Definition ## What Existing Client Means in a Contract An Existing Client clause identifies which individuals or organizations count as customers who already have, or recently had, a commercial relationship with the contracting party. This distinction matters because many agreements treat existing clients differently from prospective or new clients, particularly regarding commission structures, referral fees, restrictive covenants, and pricing terms. The definition acts as a boundary line that determines who falls inside or outside the scope of specific contractual protections or obligations. The concept is especially common in [supply of services agreements](https://www.genieai.co/en-us/template-type/supply-of-services-agreement), agency arrangements, and consultancy contracts, where the parties need clarity on whether a customer relationship predates a new agreement or arises because of it. Without a clear definition, disputes can arise over whether a commission is owed, whether a non-solicitation clause applies, or whether a discount properly applies to a given customer. ## How Existing Client Is Defined or Measured Most definitions of Existing Client combine two elements: a qualifying activity (receiving services or products) and a time window during which that activity must have occurred. The sample wording above uses a two-year look-back period, meaning anyone who received services within the past two years, or who currently receives them, qualifies. Other contracts use shorter or longer windows, such as six months or five years, depending on the nature of the industry and the sales cycle involved. Some agreements measure the relationship by transaction volume or invoice history rather than mere elapsed time, requiring proof of at least one completed purchase or signed statement of work. Others tie the definition to whether the client appears on a specific list maintained and updated by one of the parties, sometimes attached as a schedule to the contract. This list-based approach reduces ambiguity but requires diligent record-keeping and periodic updates. - Time-based definitions: activity within a stated number of months or years - Transaction-based definitions: at least one completed sale or engagement - List-based definitions: named clients on an agreed schedule or database ## Where Existing Client Appears in Agreements The term surfaces most frequently in sales and marketing contracts, referral agreements, and agency or distribution arrangements, where commissions or fees depend on whether a customer was already known to the business before a new intermediary got involved. It also appears in [managed services agreements](https://www.genieai.co/en-us/template-type/managed-services-agreement) and [cloud services agreements](https://www.genieai.co/en-us/template-type/cloud-services-agreement), where renewal pricing, grandfathering clauses, or loyalty discounts may hinge on client tenure. Non-solicitation and non-compete clauses often reference Existing Client to carve out permissible business activity, allowing a departing employee or contractor to continue serving clients they brought to the business independently of their employment, while restricting solicitation of clients acquired through the employer. Industries such as [consultancy](https://www.genieai.co/industry/consultancy) and [finance](https://www.genieai.co/industry/finance), where relationships are long-standing and referral-driven, rely heavily on precise Existing Client definitions to avoid disputes when personnel move between firms. ## Why the Exact Wording Matters Ambiguity in the definition of Existing Client can create significant financial consequences. If a commission agreement fails to specify the look-back period clearly, a dispute may arise over whether a customer who last purchased three years ago still counts as existing, potentially affecting whether a sales representative is entitled to payment. Similarly, vague wording in a non-solicitation clause could unintentionally allow a former employee to poach recently acquired clients by arguing they fall outside a narrowly drawn definition. Courts interpreting these clauses under the law governing the contract will generally hold parties to the plain meaning of the words used, so any gap in the definition is unlikely to be filled favorably for the party seeking to rely on it. Precise wording protects both the business granting client access and the individual or entity relying on the definition to determine their rights and restrictions. ## Drafting Considerations When drafting an Existing Client clause, parties should specify the exact time period, the qualifying activity (purchase, subscription, ongoing service), and whether the definition is static or updated periodically. It is also wise to clarify how disputes about client status will be resolved, for example by reference to invoicing records or a maintained client list attached to the agreement. Drafters should consider cross-referencing this definition consistently throughout the contract, particularly in commission, confidentiality, and restrictive covenant sections, to avoid inconsistent interpretations. Industries with long sales cycles, such as [real estate](https://www.genieai.co/industry/real-estate) or [insurance](https://www.genieai.co/industry/insurance), may benefit from longer look-back periods, while fast-moving sectors like [technology](https://www.genieai.co/industry/technology) may prefer shorter windows to reflect rapid client turnover. ## Context ### Relevant circumstances - When managing and targeting marketing operations for the [Organization Name] - During the review or termination of current business contracts and relationships ### Relevant sectors - Consultancy - Finance ## Relevant contract types - [Supply of services agreement](https://www.genieai.co/en-us/template-type/supply-of-services-agreement) - [Managed Services Agreement](https://www.genieai.co/en-us/template-type/managed-services-agreement) - [Cloud Services Agreement](https://www.genieai.co/en-us/template-type/cloud-services-agreement) --- This is the Markdown representation of [https://www.genieai.co/en-us/define/existing-client](https://www.genieai.co/en-us/define/existing-client), provided for AI agents and crawlers.
