The sales industry is known for using a variety of acronyms in their day-to-day communications. So much so that it can be quite confusing. Further complicating matters, there are abbreviations for different sales job titles too, which can mean different things in different companies and verticals.

If you are struggling to know who’s who in sales organizations and what responsibilities each of them holds, here’s a list of inside sales role acronyms, grouped by job type, including what they mean and what each does.

Lead Qualification Sales Job Titles

There are two types of roles in the lead qualification category. Those that focus their efforts primarily on inbound leads and those that focus on identifying and qualifying outbound leads. They do not close deals. These lead qualification positions are solely responsible for creating and qualifying new sales opportunities to hand off to closers. Doing so allows deal closers to focus their efforts on creating revenue.

These sales jobs are qualifiers that contact their prospects through a variety of channels including email, social media, and phone calls. Their success is often measured based on metrics such as the quantity of emails and phone calls. The number of qualified leads passed to closers and appointments set with these leads may also be tracked to evaluate their success. To optimize call volume and efficiency, dialers and automated CRM activity logging are often used.

Inbound Sales Roles

Sales Team RolesInbound qualifiers focus their efforts on inbound leads. Their lead sources include web form submissions, downloads of marketing content such as e-books and white papers, plus those from webinars and trade shows. These sales roles also handle inbound calls from marketing ads. Having customer intent data handy can improve results for these reps by providing them with valuable intel. The following are their most common job titles:

ISR – Inbound Sales Rep

LDR – Lead Development Rep

LRR – Lead Response Rep

MQR – Marketing Qualification Rep

MRR – Market Response Rep

Outbound Sales Roles

When communicating with these leads, personalization really improves results. They are often known by the following names:

ADR – Account Development Rep

SDR – Sales Development Rep

BDR – Business Development Rep

Sales Closer Roles

Sales closers are quota-carrying reps who receive hot prospects from lead qualification reps and work them until they close the deal. It is often recommended that closers stay in touch with new customers, after the close, throughout the setup and launch process to ensure a smooth transition.

AE – Account Executive (a.k.a. closer or salesperson)

SE – Sales Executive

ISR – Inside Sales Rep

Management of Current Customers

Like those in the lead qualification reps, there are two types of reps under “management of current customers”. One of these sales roles focuses solely on retention while the other grows accounts through cross-selling and up-selling.

Retention

These reps launch new clients and assist them with their ongoing requirements to promote satisfaction and success to ensure renewals. Their goal is to help their customers get more value from their product through hands-on help, education, and training. They are identified by the following titles:

CSR – Customer Success Rep

CSM – Customer Success Manager

CSE – Customer Success Executive

CSE – Customer Support Executive

Happiness Hero

Retention and growth

These reps carry a quota.  They perform all the retention processes and pursue cross-sell/up-sell opportunities to grow their accounts. They do so through a variety of methods such as email, phone calls, web presentations, and social media. Below are the most common titles for this position:

AM – Account Manager

AR – Account Rep

One thing all these reps must do is communicate effectively with their prospects and customers. A best practice to sharpen their pitch is to routinely listen to their own call recordings and those of other successful team members. Tracking metrics is also an excellent practice to ensure they’re on track to hit their numbers. Of course increased efficiency is necessary for success in all these roles. Sales process automation is a great way for these reps to accomplish this.

Although this list is extensive, there is an ever-growing variety of creative titles assigned to inside sales roles.
