What is an SDR?
SDR is the sales development person who makes initial contact and qualifies opportunities before advancing them to the next sales stage. At an agency, your job may include researching companies, understanding interest in the service and arranging a conversation with the person responsible for closing. The design of the role changes depending on the size of the team and the process adopted.

Why does role matter to an agency?
A marketing service usually requires a needs assessment before a proposal. The SDR helps to separate contacts that match the profile served from those who do not yet have an identified need or interest in talking. By combining qualifying questions and recording responses, the agency reduces reliance on individual memory when moving to the closer.
In small teams, one person can prospect and also lead meetings; in others, the functions are divided. The important thing is to define who is responsible for the next contact and what information needs to be available so that the potential customer does not have to repeat the entire conversation.
How can you measure activity and quality of qualification?
A simple measure is the proportion of qualified contacts who arrive at the meeting. If, in a period, 20 qualified contacts generated eight meetings held, the calculation is eight divided by 20, or 40%. Record the date and definition used for qualified and also track reasons for absence or postponement.
This example is not a universal goal nor does it demonstrate that the team generated eight sales. Volume, adequacy of contacts and quality of the handoff need to be analyzed together. To compare time periods, use consistent criteria and examine whether customers' decision cycles are similar.
What errors harm the SDR's work?
A frequent mistake is to count any response as a ready opportunity, even when there is no interest or suitability for the service. Another is to schedule a meeting without recording what motivated the contact, who participated in the decision and what was agreed. This makes it difficult to prepare who will lead the next conversation.
It is also worth avoiding goals that encourage insistence on uninterested contacts. Review messages and the origin of lists, respect contact preferences and evaluate the rules applicable to the channel. Results depend on the offer, market and execution, in addition to the work of a single function.
How does Zenit OS support this business routine?
In lead management, the team can track contacts and their information; the calendar helps you organize meetings. The meeting filters by SDR and the schedule board offer query points for management, as long as the data is filled in correctly. ZenitProspect also offers conversation management and outbound messaging via WhatsApp for agencies with access to the module.
Access varies depending on plan, permissions and configuration. Before adopting a measure, agree on its definition with the people recording the data and check how it appears in available reports.

Frequently asked questions
Are SDR and closer the same function?
In split processes, the SDR generally qualifies and forwards, while the closer conducts the negotiation. A small team can combine both responsibilities.
Does a scheduled meeting equate to a sale?
A scheduled meeting does not yet represent a sale. Scheduling is a previous step; meetings held, proposals and closing must be evaluated separately.
Does every lead need to go to a meeting?
The team must verify interest and suitability for the offer before forwarding the contact to the next stage.
Does Zenit OS guarantee SDR productivity?
The tool supports the organization of work; results depend on the quality of data, process and execution.
