Outsourced SDR vs an AI Sales Agent: What Each One Costs
tl;dr
Outsourced SDR agencies commonly run three to fourteen thousand US a month. A fully loaded in-house SDR lands nearer ten to fourteen thousand once tools, management and ramp are counted. AI sales agents start around nine hundred and climb fast. All three are priced for a business with a sales budget, which is the actual problem if you are a small brand chasing independent stockists.
Three ways to buy sales capacity
Hire someone. Rent someone. Or buy software.
They are priced very differently and they fail very differently. Most comparisons only cover the first half of that.
| Option | Typical monthly cost | What you are buying |
|---|---|---|
| In-house SDR, fully loaded | $9,800 to $14,200 | Salary, benefits, tools, data, management, ramp |
| Onshore outsourced SDR | $7,000 to $10,000+ | A dedicated rep and the agency's process |
| Multi-channel SDR program | $4,000 to $8,000 | Email, phone and LinkedIn run for you |
| Nearshore or offshore SDR | $1,000 to $5,000 | A seat, usually with less category knowledge |
| AI SDR platforms | From ~$900, often far higher | Software that prospects and sends |
| Independent sales rep | 5 to 15% of net sales | Relationships, paid only on results |
The make-or-buy question is older than any of this
Williamson won a Nobel for the framework you are actually using here.
His argument: you do a thing in-house when the transaction needs assets and knowledge specific to you, and you buy it on the market when it does not.
So the real question is not what an SDR costs. It is how much of your selling depends on knowing your category, your buyers and your product specifically.
If the answer is most of it, outsourcing the judgement will disappoint you no matter what you pay.
What the outsourced number buys
A process, a data stack, and someone whose full-time job is your top of funnel. Genuinely valuable when your deal size supports it.
The honest comparison is not retainer against salary. It is cost per held meeting against your fully loaded internal cost per held meeting.
Where it goes wrong is incentives. An outsourced rep is measured on meetings booked, not on accounts that reorder in eight months.
If you sell into independent retail, a meeting is not the unit that matters. A shop that reorders is.
What the AI number buys, and the productivity paradox
The AI SDR category was built for B2B revenue teams. It prospects from a contact database, personalises at volume, sends, and books meetings.
Gartner expects AI agents to outnumber human sellers ten to one by 2028.
In the same forecast, fewer than forty percent of sellers will say those agents actually improved their productivity.
Sit with that for a second. Ten times the agents. Most sellers still saying it did not help.
Gartner's own read is that the wins go to organisations that fix data and workflow rather than bolt on a tool, and that sales teams given AI-enabled next best actions are 2.6 times more likely to hit commercial growth.
The thing that separates the two groups is not the model. It is whether a human is still making the call.
The question no pricing page answers
Who approves what goes out.
An outsourced SDR sends in your name. An autonomous AI SDR sends in your name.
In both cases the first time you see the email is usually after a prospect has replied to it. Or complained about it.
For a small brand, sender reputation and brand voice are the same asset. There is no second domain.
That makes approval before sending a structural question, not a preference. It is the thing worth checking hardest.
Which fits a consumer brand chasing stockists
None of them, honestly. Not as designed.
They were built for software companies with a sales budget, contract values in the thousands, and a definition of success that ends at a booked meeting.
Your unit is a shop that reorders. Your order values are in the hundreds. Your budget is not four thousand a month.
The shape that works is to do the breadth yourself, or with software that drafts and waits for your approval, keep spend near zero while you prove the model, and buy human capacity only for accounts where a person in the room changes the answer.
Synchronise sits deliberately at that end. Free tier, paid to A$249 a month, and no agent can send, post or spend without you approving it first.
Questions
- How much does an outsourced SDR cost?
- Most services run about three to fourteen thousand US a month. Multi-channel programs covering email, phone and LinkedIn sit around four to eight thousand, onshore dedicated reps seven to ten thousand and up, offshore seats from roughly one to two and a half thousand.
- Is outsourcing cheaper than hiring an SDR?
- Usually on total cost. A fully loaded in-house SDR runs roughly ten to fourteen thousand a month once salary, benefits, tools, data, management and ramp are counted. Run the comparison on cost per held meeting, not headline price.
- Can an AI sales agent replace an SDR?
- For the volume half of the job, largely yes. For the judgement half, only if a person still approves what goes out. Gartner expects agents to outnumber sellers ten to one by 2028 while fewer than forty percent of sellers report a productivity gain, which tells you the tool alone is not the thing that works.
- What is a fractional sales team?
- A part-time or shared sales resource split across several companies. Lower monthly cost than a dedicated hire, and correspondingly less focus on your category.
