FRC—First Contact Resolution, or “once & done” —is a widely used metric in customer relationship management systems. It is designed to measure an organization’s ability to resolve a customer’s request on the first contact. As such, it reflects both operational performance and the perceived quality of the experience.
Behind this common definition, several calculation methods coexist. They are based on different data sources and analytical approaches: CRM data, contact information, telephone records, customer surveys, or internal evaluations. Here is a structured overview.
Summary
"Once & Done," also known as First Contact Resolution (FCR), is emerging as one of the key KPIs for modern customer experience . This metric measures a company’s ability to resolve a request on the first contact, without follow-ups or additional interactions. Beyond being a simple operational metric, it reflects the organizational maturity of customer relations: process quality, agent autonomy, access to data, and omnichannel efficiency.
Against a backdrop of cost pressures and rising customer expectations, “Once & Done” is becoming a strategic asset. It simultaneously improves customer satisfaction, reduces contact volumes, and optimizes the financial performance of customer service centers. The challenge is no longer just to respond quickly, but to resolve issues permanently.

1. Supervisor/Quality Report
First method for calculating the FCR: internal assessment through quality assurance systems.
In this case, the “once & done” process is based on an analysis of call recordings or quality checks conducted by supervisors. The evaluator reviews the interaction (call, email, chat, etc.) and determines whether it has been fully processed. The implicit statement is as follows:
“I assess that the interaction has been fully processed.”
If the interaction meets the criteria defined in the quality matrix (response provided, steps taken, information shared, no further action required), it is recorded as resolved on the first contact.
The FCR is then calculated by aggregating all the valuations performed over a given period (every month, for example).
This approach makes it possible to ensure compliance with best practices and to align the FRC with internal data processing standards. It is based on a shared framework defining what constitutes a complete data processing operation.

2. Customer Statement
Second method: data collection through satisfaction surveys.
The customer is interviewed immediately after their interaction. The question can take various forms:
- "Was your issue resolved during this interaction?"
- "Do you think you'll need to contact customer service again about this request?"
The FRC therefore represents the proportion of customers who report that their request was resolved on the first try.
This approach is based on the customer’s perception. It does not directly measure the actual number of follow-up contacts, but rather the intention or sentiment expressed. It can be incorporated into post-contact surveys and analyzed in conjunction with other indicators, such as overall satisfaction or perceived effort.
Customer feedback thus makes it possible to incorporate the customer’s voice into the “once & done” measurement process, regardless of IT system constraints. This method is widely adopted because it is easy to implement.
3. Calculating First Call Resolution (FCR) over the Phone
Third option: FRC focused on the telephone channel.
In this configuration, the analysis focuses solely on calls. The rule is generally phrased as follows:“
” “The customer has not contacted the company by phone within X days of their initial call.”
Data from telephony tools makes it possible to identify consecutive calls from the same customer over a given period. If no new calls are detected within the defined time window, the initial contact is considered resolved.
Telephone FRC has historically been one of the most widespread forms of “once & done.” It serves as an operational metric for managing teams in a call center environment, particularly when the telephone is the primary channel.
The duration of the observation window used (for example, 7, 10, or 15 days) should be specified, as it directly influences the measured result. It is also possible to calculate the FCR on a cumulative basis: the percentage of customers who did not call back within 7, 10, or 15 days.
4. Omnichannel First Contact Resolution (FCR) Calculation
Fourth option: FRC Contact with an omnichannel approach.
Here, the analysis isn't limited to a single channel. The rule is:"
" "The customer has not contacted the company again through any channel within X days of their initial contact."
This approach involves consolidating all customer contact channels: phone, email, mail, digital forms, messaging, and so on. The goal is to track the customer’s overall behavior after their initial contact.
The calculation is based on identifying an initial contact, followed by the potential detection of a new contact associated with the same customer within the defined time period. If there is no follow-up contact, the contact is counted as “once & done.”
This approach makes it possible to integrate cross-channel customer journeys and avoid a view limited to a single channel. However, it requires the ability to track all of a customer's interactions.
5. FRC Calculation Based on a Single Customer Request
Fifth approach: the FRC based on the concept of a request or case file.
Under this approach, a case is considered “once & done” if the customer has contacted the CRC only once regarding a single request. The wording is as follows:
“The customer has contacted the CRC only once regarding the same request.”
The calculation is based primarily on the cases or files recorded in the CRM. Each request is identified, tracked, and closed. If only one contact is associated with the request, it is considered resolved upon the first contact.
This method emphasizes case management and the quality of reason coding. It relies on the ability to correctly link different contacts to the same request and to distinguish between separate requests from the same client.
As a first step, if the “cases” or “files” field is not filled in the CRM, the “once & done” metric can be calculated based on the customer contact reasons entered by the advisor.
"Once & Done" is an indicator that must be explicitly defined
There is no single definition of “once & done.” Depending on the organization, it can be measured:
- based on an internal evaluation
- through the customer declaration
- only on the phone
- in an omnichannel approach
- or at the CRM query level
Each method corresponds to a specific scope, a specific data source, and a distinct analytical approach. To ensure the indicator is easy to understand, it is essential to specify the definition used, the time frame applied (if applicable), and the systems used for the calculation.
The FRC remains a key KPI for managing customer relationships. Its relevance depends on the clarity of its definition, the consistency of its tracking over time, and alignment among operations, quality, and marketing teams regarding what “resolved on the first contact” actually entails.
A metric that is difficult to compare across companies
While the term “once & done” is widely used, the way it is calculated varies significantly from one organization to another. Several factors may differ:
- the selected observation period (7 days, 15 days, 30 days, etc.)
- whether or not to take into account hot transfers between advisors
- whether or not to include channel changes
- choosing between a behavioral or self-report measure
- the scope of the analysis (contact, case, specific channel)
The goal, therefore, is less about finding an external benchmark and more about ensuring consistent measurement over time. When tracked using a fixed definition, the “once & done” metric becomes an indicator of progress. It allows us to assess the impact of the actions we’ve implemented: improving scripts, expanding the knowledge base, training teams, streamlining processes, or optimizing customer journeys.
