How to Build an SDR Development Program for B2B Companies

An SDR development program for a B2B company is a managed path that a new rep walks through, with a gate at the end of each stage. Four stages cover the first 90 days: setup, practice, supervised outreach and independent work.

Four supports sit around those stages:

1. A curriculum built on the channels you actually sell through. For most B2B teams that means LinkedIn and email.
2. A quota that ramps from a pipeline target.
3. A manager who inspects real work every week.
4. Written criteria for promotion to account executive (AE).

Then comes one decision. You can build all of it in-house, split it with a partner, or hand execution to an outside team. Our own work is mostly email and LinkedIn, so those are the channels this program trains.

Most companies skip the path, which is a big reason outsourced SDR programs fail too. They hire a rep or an agency, hand over a login and a target, and wait. When nothing comes, they hire again.

One US founder came to my team after three agencies. He was about to move his ad budget into outbound, because that budget had never produced a positive return. In 60 days we emailed 70,000+ people and got 335 interested leads.

The lesson for anyone designing an SDR program: swapping the people does not fix a missing system. Drop a new SDR into a company with no stages, no gates and no handoff standard, and you are making the same bet with a payroll attached.

What does an SDR do in a B2B company, and what should the role own?

A sales development representative (SDR) does four things. An SDR finds the right people at the right companies, starts conversations with them, qualifies them, and hands a booked meeting to an AE. The output is a qualified opportunity. Closed revenue is the AE's number.

Booking a call and closing a sale are two different jobs, and each needs its own skills.

The role exists because prospecting and closing compete for the same hours. An AE who builds lists in the morning and writes proposals in the afternoon ends up doing neither well.

The handoff note is where the SDR's work becomes visible. The AE should be able to walk into the call without asking basic questions again. The note covers five things:

• who the person is
• what they decide
• what they actually replied
• which problem or trigger came up
• what they agreed the call is about

If the AE opens with "so, why are we talking?", the SDR has not finished the job.

What should the first 30, 60 and 90 days look like?

A Forrester best-practice report on seller onboarding from May 2025 identifies the tension. Companies want new reps selling on day one, and that rush can cost revenue. The report warns that letting an untrained rep loose on buyers can be a "disaster for the buyer, the brand, and the contract" (Forrester).

Gates solve this. Speed to field still matters, so every stage has a short time box. But a rep moves on when they pass the gate, and the calendar alone never moves them. One B2B tech client of ours started from zero qualified calls and reached 40+ a month within 90 days, so 90 days is a fair window for judging a ramp.

Two details make this table work.

The sending side warms up while the rep practices. New email accounts need at least 10 to 14 days of warm-up before they send to buyers, and that fits inside stage 2, so no time is lost.

Stage 3 runs at low volume on purpose. If a message flops on a small test, sending it to ten times as many people just flops louder, and costs more. That is why the manager reads every thread first, and why raising the volume is the last step.

How do you build the curriculum if your outbound runs on email and LinkedIn?

Train the work the rep will actually do on day 31. For most B2B teams, the first touch is LinkedIn and the email comes after it. By the time the email lands, the name is already familiar. If you want the full mechanics, this is how my team treats LinkedIn and email as one outbound sequence.

Titles. Before I build a list, I go through a client's past projects and find out who actually made each decision. Then I take generic titles like Assistant, Manager and Associate out of the search completely. Teach your rep that habit in week one and many list problems never appear.

Profile. About 90% of the LinkedIn headlines I see are generic. A rep's profile is a client-facing page, not a CV. Even a mediocre message lands better when the profile behind it looks credible than a polished one sent from an empty account. Buyers look the rep up before they reply, so module 3 comes before any live message.

Message. In a first message I sell the meeting, never the service. Put proof in too: who you helped and what changed for them, inside the message itself. Train both until the rep does them without thinking.

Sequence. Two messages do not make a sequence. For every sequence I plan at least 5 to 6 touches, best spread over both channels. Content on LinkedIn gets attention. Direct messages get deals.

Operating basics. I do not care which CRM a team uses, as long as no lead gets lost. Split the territory per rep and per account, so two reps never write to the same person.

The rep does not configure the email setup, but they should know that SPF, DKIM and DMARC (the records that prove to inbox providers your email really comes from you) must be in place before any volume goes out, because nothing else works without them.

How do you set the SDR quota ramp without guessing?

Start from the pipeline you need and work backwards to meetings. Here is a worked example. Swap in your own inputs.

The inputs: one AE needs 4 new outbound deals a quarter at an average deal of $50,000. I use that size as a middle case, since deals usually start at USD 10,000 and often reach six or seven figures. That is $200,000 in new revenue per AE per quarter. The steps below turn those 4 deals into meetings.

1. Deals to held meetings. At a 20% close rate on held meetings, 4 deals -> 20 held meetings a quarter. I use about 20% as a working benchmark for high-ticket B2B, and it varies by niche.
2. Held to booked. Some booked meetings never happen. Across our own funnels, about one booked meeting in five, sometimes one in four, never happens, so I plan for that drop. Taking one in five: 20 held -> 25 booked a quarter.
3. Booked to replies. Meetings usually come from 10% to 50% of replies. At 25%, 25 booked -> 100 replies.
4. Replies to people reached. A reply rate of about 1% is usual for us. So 100 replies -> 10,000 people a quarter, or about 3,300 a month.
5. Quota. 25 booked meetings a quarter -> about 8 a month for a fully ramped rep.

Sanity-check the result against a second rule. For 30 to 35 booked meetings a month, expect to contact 10,000+ people in that month, roughly 300 people per meeting. The example above needs about 400 per meeting (10,000 people for 25 meetings), so it is slightly more cautious than that ratio.

The close rate is the input that moves most, so take yours from your own CRM.

Volume changes the rates too. At thousands of emails a day, reply rates often fall to 0.5%. A small market with very specific, heavily personalized messages can reach 15% to 17%, with about 75% of repliers interested. Averages fall as volume rises. There is more on the revenue side in how many meetings you need to hit a revenue target.

Then ramp the quota to match the stages (for why ramps stall and reps leave, see SDR ramp and turnover):

Which numbers should the manager review, and how often?

Review each rep on activity, quality and outcome. Track three numbers for each, and check each on its own schedule. The dashboard itself is covered in SDR metrics.

Read the layers in order. If activity is low, coach habits. If activity is fine and quality is low, fix the list or the message. If both are fine and outcome lags, look at the offer and the handoff.

For the activity layer, I would rather a rep aim to start 50+ conversations a month than chase 10 booked calls. Conversations come first, and calls come out of them.

Judge the outcome layer slowly. In B2B, a sales cycle of 6, 9 or 12 months is common. A meeting booked in month two may close 4 or more months later. A program judged on month-one revenue gets cancelled while it is working.

What coaching system makes SDRs better?

Gallup's research covers 27 million employees in 2.5 million+ work units. Its estimate: the manager explains at least 70% of the difference in engagement between one business unit and the next (Gallup).

That measures engagement rather than quota, so treat it as a pointer to how much a manager matters. It does not prove that coaching lifts SDR output.

The same research estimates that about one in 10 people have high talent to manage. Another two in 10 can perform at a high level if the company invests in coaching and development plans for them.

So choose the SDR manager on purpose. Your best rep is not automatically the one in 10.

The manager's job here is inspection, feedback, and development planning. Every week, they open four things:

1. A random sample of 20 contacts from each rep's list, checked for title and fit.
2. The live sequence, read the way a buyer would read it.
3. Every reply thread from the week, including the ones the rep marked as dead.
4. Every handoff note, side by side with what the AE heard on the call.

Random feedback comes from managers who review whatever they happen to notice. Avoid it with one written development item per rep per week. Tie each item to a gate or to one of the review numbers, and check it the following week.

The rep's side of the deal matters as much. When I coach, I ask people to follow the instructions, because coaching someone their own way only gets them the results they already have. That applies to a new SDR too: run the sequence as written until Gate 3, then change it with the manager.

What does promotion from SDR to AE actually require?

Make the path visible from day one: SDR, then senior SDR, then AE.

• SDR: prospects inside a territory someone else designed.
• Senior SDR: owns a larger territory, shapes its list, and reviews a new rep's lists.
• AE: owns a pipeline and its forecast.

Time in seat can be a minimum, but it should never be the trigger for promotion. Use this table instead:

The last row is the easiest to skip. Before anyone takes calls on their own, I want them to know the pitfalls of a sales call, how this buyer decides, and where selling ends and closing begins.

A rep who has only listened to calls sees the 2 or 3 contracts that got signed. I see the 97 or 98 prospects who walked away, and supervised calls teach a rep to see them too. Give promotion candidates several supervised discovery calls with an AE in the room, and let that AE sign off, before the title changes.

Should you build, hybridize or outsource the SDR program?

Decide by what you already have in place.

Use these decision rules:

• No proven offer yet: do none of the three. Fix the offer and the proof first. My team does not take on companies starting from zero.
• A manager who has run outbound, and two or more reps planned: build. The stages and gates above are your program.
• AEs with spare call time, but nobody to run lists, sending and sequences: go hybrid.
• Conversations needed this quarter, with no one to manage reps: outsource execution and keep closing in-house. The system only works if someone has time to jump on the calls.

Whichever you pick, cheap lead generation shops that blast emails cannot rescue a business with broken foundations, and neither can a new hire. Ask any partner for the names of the people who would write your sequences, and check their LinkedIn profiles before you sign. I compare the two ownership models in more depth in bringing outbound in-house.

For the in-house and hybrid columns, SDR pay swings too much by country and seniority for one number to be honest. Price them from local salary data, plus the manager's hours and the tool stack, and compare the result with the sourced figures in what a B2B meeting costs and SDR cost by country.

To price the outsourced column, here is how my agency works. I run one, so weigh this part with that in mind. The fee starts from USD 3,000 (about EUR 2,500) per month and goes up to USD 10,000+ for more channels, markets or volume. Tools, domains, mailboxes and data are paid by the client directly, outside that fee.

We launch about 15 days after signing. From you we need one 60-minute Zoom call and a handful of emails.

You can leave with one month's notice, since there is no minimum term. Give it 3 months or more: a campaign needs feedback and iteration, and across the industry it takes about 6 months to run at full strength.

If you build in-house, start this week by writing the four gates on one page, before you post the job ad. Fix the program first. Then hire.
