If you’ve never hired a sales development rep, here’s the part nobody mentions when they pitch you on getting one.
An SDR sits at the front of your sales process. They don’t close deals. Their whole job is to find people worth talking to and get them to agree to a conversation. They build the list, figure out who’s actually a fit, dig up something relevant about each one, write the email or make the call, follow up four or five times, and when somebody finally says “sure, let’s talk,” they hand that meeting off to an account executive. The AE is the closer. The SDR is the one grinding all day to get the AE someone to close.
That handoff is the entire model. SDR fills the top of the funnel, AE works the bottom. It’s a good model. The problem is what the top of that funnel actually costs.
Where the time really goes
People picture an SDR on the phone all day, charming their way into meetings. That’s not the job. A rep who’s doing it right spends maybe a third of their day actually talking to prospects. The other two thirds is research and admin, and it’s brutal.
Pull a list. Check whether each company is even a fit. Find the right person inside it, then find their email, then check the email is real so you don’t torch your domain. Read the company’s recent news so the message isn’t generic filler that gets deleted in two seconds. Write something that sounds like a human wrote it to a human. Log all of it in the CRM. Then do the follow-ups, because almost nobody replies the first time.
Do that properly and one good touch, the kind that actually earns a reply, takes ten, fifteen, twenty minutes. So a rep doing real work tops out around ten or fifteen of those in a day. Not a hundred. Ten. The rest of the day got eaten by the work nobody sees.
The part nobody adds up
Now the money. A typical SDR runs somewhere around $55K to $65K in base, and closer to $80K to $90K all in once you count commission. That’s before you add payroll taxes and benefits, before the tools they need to do the job, before the three to five months of ramp where you’re paying full freight for someone who isn’t productive yet, and before the manager who has to coach them.
Stack all of that up honestly and you’re north of $90K in year one for one seat.
And SDRs don’t stick around. Average tenure in the role is about a year, maybe a year and a half. So right about the time they get good, they leave for an AE job somewhere, and you start the ramp over from zero.
So here’s what you’re really buying: someone who costs you ninety grand and up, spends two thirds of their time on work that isn’t selling, maxes out at ten or fifteen real touches a day, and is probably gone in eighteen months. I’m not knocking SDRs. I’ve hired them. I’ve been one. I’m saying we ask a person to spend most of their day doing something a person should never be doing.
Almost none of that grind is human work
Look at that list again. Finding companies. Finding contacts. Verifying emails. Reading public information. Drafting a first version. Logging it. Spacing out the follow-ups. None of that is human work. There’s no judgment in it, no relationship, no charm. It’s just volume and patience, which is exactly what people are worst at and machines are best at.
So I stopped paying people to do it. I build systems that handle the grind. The list, the research, the personalization, the qualification, the follow-up cadence, all of it gets done before a rep ever sits down. The rep opens a queue that’s already built, already researched, with a draft that’s actually about that specific account, and they spend their time on the only part that needs a human.
With one client, AccuTrain, per-rep output went from about ten personalized touches a day to over a hundred. Same people. They just stopped doing the part a machine does better. The system doesn’t ramp for four months, doesn’t take PTO, doesn’t burn out, and doesn’t quit in the fall to go be an AE.
That’s the cost savings, and it’s not subtle. You get the output of a small SDR team without the salary stack, the turnover, or the management overhead. You still need a human for the human part, the actual conversations, the read on a deal, the relationship. That’s where your money should go. That’s the part worth paying a person for.
An SDR is a person doing a system’s job. Pay the person to be human. Let the system do the grind.
