In most B2B companies, the decision comes to the same place, where referrals and inbound marketing aren’t enough anymore, and somebody offers outbound. But what to choose then is the tough part? Should you build an outbound team yourself by hiring SDRs, or should you outsource that process to a specialized team? Both options are possible. But both may also be a waste of six months and a good sum of money.
Here is how to approach it.
The US-based SDR will make a salary range of $70,000 - $95,000 annually, depending on seniority level and location. But it is just the beginning. Add up the commissions, payroll taxes, benefits, and software licensing seats for each SDR, and your fully-loaded cost of an SDR goes far beyond the basic number.
Ramp period comes next. The average SDR usually needs 3 to 6 months to become fully ramped up. It means that during this period he or she learns your product, target customers, objections and tools. Meanwhile, you pay full salary for the SDR, but results come gradually.
And turnover makes the situation even more difficult. SDR tenure periods are relatively short, so each resignation initiates the ramp period again. So, if your SDR resigned after nine months, you could have only 3-4 months of his full productivity.
All of this does not mean that building an in-house sales development team is a bad idea. But it shows that it should not be compared to agency fee versus salary. It should be compared to the fully-loaded cost of one productive seat versus the same productivity of an external team.
The hiring of the representative is the overt aspect. The outbound process relies on infrastructure, which somebody needs to construct and maintain.
The final one is the one which gets skipped most frequently by teams. Founders think that the SDR should take care of that, but SDRs usually get hired for writing emails, making calls, and scheduling meetings, and not fixing DNS issues. Since there is no one owning the technical deliverability aspect, it gets overlooked and your response rates go down.
Outsourced outbound is usually priced in one of two ways.
Retainers are the most common. Monthly fees commonly run from about $3,000 to $15,000, depending on volume, channels, and whether list building, copywriting and strategy are included. The lower end often covers email only at a set monthly contact volume. The upper end tends to add more channels, dedicated staff and deeper account research.
Pay-per-meeting models also exist. You pay a set fee for each qualified meeting booked, sometimes alongside a smaller base fee. This shifts risk toward the provider, but it puts a lot of weight on how "qualified" is defined.
An experienced B2B cold email agency typically arrives with its own infrastructure: domains, warmed inboxes, data sources and a sequencer already running. That is a large part of what you are paying for. You skip the hiring cycle and most of the setup, and campaigns can often go live within weeks instead of months.
When you compare options, set these fees against the fully loaded, ramp-adjusted cost of an in-house seat, not against base salary alone.

Outsource when:
Many companies do both in sequence: outsource to find what works, then bring the proven playbook in-house once the numbers justify a full team.
If you go the outsourced route, get clear answers to these before you sign.
Who owns the domains and inboxes? Some providers send from domains they own, so the sending history leaves with them when the contract ends. Others set up domains in your name that you keep. Know which model you are buying.
How are meetings counted? Ask for the exact definition of a qualified meeting. Does it have to match your ICP on company size, industry and job title? Does a no-show count? What happens if the prospect turns out to be a poor fit?
What does the ramp look like? Ask how long domain setup and warm-up take, when the first campaign goes live, and what results are realistic in month one versus month three.
It is also worth asking how they source data, how they handle opt-outs, and how they keep outreach focused on business contacts in their professional role. Specific, confident answers are a good sign the partner takes deliverability and compliance seriously.
There is no universal answer, but the right one usually becomes clear once you put real numbers next to your situation. Run through these five questions:
Mostly yes points toward building in-house. Mostly no points toward outsourcing first, learning what works, and revisiting the decision once you have proof.
