Outsourced SDR for Partner-Sourced Pipeline: SDRs Who Call as Your Partner
Short answer: An outsourced SDR is a sales development rep you contract from an SDR agency instead of hiring in-house. But Forecastable’s SDRs work differently, because they call as your partner, under the partner’s name and with its approval, inside partner GTM motions. So the pipeline they create counts as partner-sourced. Every Partner-Sourced Pipeline program includes a real human SDR making about 1,000 cold calls a month. Still, we’re not a generic SDR agency. If you want cold calls in your own name, hire one of those.
What is an outsourced SDR?
An outsourced SDR is a sales development representative supplied by an outside firm. The firm hires, trains and manages the rep. Then the rep researches accounts, runs outreach by phone, email and LinkedIn and books meetings for your closers. So you get the output without carrying the headcount.
You’ll hear the same idea under other names:
- SDR agency: a firm that supplies a team of SDRs.
- SDR as a service: sales development sold as a monthly service, not a hire.
- Outsourced BDR: the same role under a different title. Some companies use BDR for outbound and SDR for inbound, but many use the terms loosely.
- Outsourced sales development: renting the whole function, including process, tools and management.
The appeal is speed. In fact, The Bridge Group’s 2025 SDR Metrics Report, a survey of 351 B2B companies, puts average SDR ramp at 3.0 months. It also puts average tenure at 1.9 years. And only 60% of SDRs hit quota, the lowest in the study’s history. So an in-house hire takes a quarter to ramp and may leave within two years.
Why outsource SDRs for partner pipeline?
Most outsourced SDRs call as you. That’s fine for cold outbound, but cold starts behind. According to Gartner’s B2B buying journey research, buyers spend only 17% of their buying time meeting potential suppliers. As I put it earlier this year, the other 83% is shaped by people like consultants, advisors and integrators. Those people are your partners. So a stranger’s call starts at a disadvantage. And calling as you breaks the moment you want partner-sourced pipeline.
Here’s the rule I give teams: if your SDR team books it, it isn’t partner-sourced. That holds even when the account list came from your partner data. After all, your partner didn’t open the door, so most programs won’t credit it. But run the same outreach with the partner, under the partner relationship, and it counts. If the terms are new, here’s how partner-sourced and partner-influenced pipeline differ.
Why your partner managers can’t be the SDRs
So who makes those calls today? Usually, nobody. That’s because partner managers are in the relationship business, not list building. Lists, calls and follow-up aren’t their job, and they shouldn’t be. The same gap shows up with Crossbeam overlaps, which is why we built an account-mapping service.
Meanwhile, your own channel SDRs can chase partners for intros. Still, the meetings they book usually land as sales-sourced. And partners rarely run the campaigns they’re handed. That’s why an independent third party works. We sit in between, run the outreach as the partner, and give every side full visibility. So build SDR coverage into your channel partner program design from day one.
How do partner SDRs compare with an SDR agency?
Here’s how the three common options stack up:

| In-house SDR | Traditional SDR agency | Partner SDR (Forecastable) | |
|---|---|---|---|
| Who the buyer hears from | You | You | Your partner, often alongside you |
| Time to first calls | A hire, plus about 3 months to ramp | Depends on the agency | A working motion about two weeks after the workshop |
| Target list | Built by your team | Built or bought by the agency | Accounts where a partner has a customer, a deal or a reason |
| Pipeline credit | Sales-sourced | Sales-sourced | Partner-sourced, per each platform’s attribution policy |
| Who often pays | You | You | Often your partners, through MDF and co-funding |
How do Forecastable’s SDRs work?
Our SDRs are real people, not AI, and they work inside the motion, not beside it. Here’s what that means:
- Calling as the partner: they call under the partner’s name, with its approval.
- Selective, not volume: they call the contacts where a call counts, not thousands of companies a month.
- Backed by a team: a campaign operations specialist runs the email and LinkedIn side, and real people handle every reply, never AI agents.
How far does one SDR go?
Every Partner-Sourced Pipeline program includes one SDR, and one SDR makes about 1,000 cold calls a month. A GTM motion is a priced, workshopped campaign run with one partner or several. Most programs run three to five of them. So in the workshop, we decide together which motions get SDR calling first.
Need more calling than that? Add a second SDR for $10,000 a month. That doubles your calls to about 2,000 a month.
What does an outsourced SDR’s month look like?
We size SDR capacity on industry averages, not on top-performer numbers. So the plan holds up when real calendars and real voicemail boxes get involved.
Here’s the default month for one SDR, from our published pricing:
| Measure | One SDR, one month |
|---|---|
| Calls | About 1,000 |
| Priority contacts | 100, each with up to five tries |
| Other contacts | 500, each with one call plus a live voicemail |
| Contacts reached | About 600 |
| Live conversations | About 91 |
The math rests on industry averages. For example, about 1 in 10 dials reaches a live conversation. So up to five tries reaches about 4 in 10 contacts. Those are illustrative planning figures, not a quote or a promise of results.
What we measure
We capture every data point the SDR creates. Here’s what you see, partner by partner:
- Calls and live conversations, by motion.
- Meetings booked and meetings accepted.
- SQOs created from each motion.
- Pipeline, by partner and by quarter.
- Cost per SQO, so every dollar competes on the same number.
And you don’t log into anything to see it. Instead, you connect through the Forecastable MCP in Claude, ChatGPT or Microsoft 365 Copilot. Eva, our AI partner ops agent, watches the data in the background.
Where do SDRs fit in Forecastable’s programs?
SDRs only work inside Partner-Sourced Pipeline, our done-for-you program for enterprises with large ecosystems. Every motion there runs on email, LinkedIn and calls. They’re also the engine behind our partner-sourced demand generation work.
By contrast, our other work doesn’t use SDRs. Accelerate My Partner Program runs alongside your partner managers, with no SDR included. Similarly, fully run webinars and field events are handled by a campaign operations specialist, not an SDR.
If you’re mainly shopping for booked meetings, read how we run appointment setting through partners. This page is about the SDR team behind it.
How should you evaluate an outsourced SDR provider?
Whoever you hire, ask five questions. They’re the same ones we hold our own SDR work to.
- Where does the target list come from? Generic lists get generic messages. We start from the accounts a partner already knows, then change the message per account.
- Which domain does the email send from? Cold email from your primary domain puts that domain at risk. So good providers buy and warm separate domains, and we do too.
- Who answers the replies? At Forecastable, people do. AI audits the work, but it doesn’t run your follow-up.
- What counts as success? Ask for meetings accepted and SQOs, not dials. I treat the SQO as the real trigger, because sales has reviewed it and logged it as a real opportunity.
- Who gets the credit? If the SDR calls as you, the pipeline is sales-sourced, even when the list came from partner data.
When is an outsourced SDR from Forecastable the wrong fit?
I’d rather say it up front. Hire a traditional SDR agency instead if any of these are true:
- You want SDRs calling as your company: our SDRs call as your partners, so without a partner in the motion, we don’t make the call.
- You want to manage the reps yourself: we run the SDR inside our motions, end to end.
- You don’t have B2B partners yet: we work only with B2B partners, such as resellers, VARs, distributors, OEMs, technology and ISV partners, agencies and consultancies, SIs, GSIs and other implementation partners, MSPs, hyperscalers, and the list goes on.
- Your story isn’t proven: use us to scale what already works through partners, not to test a brand-new pitch.
How much does an outsourced SDR cost with Forecastable?
Our SDRs come inside the Partner-Sourced Pipeline program. It starts at $50,000 a quarter, and that activates a dedicated team: a campaign operations specialist, one SDR and the platform, with Eva and full MCP access. It’s the floor, not a cap.
| Item | Price |
|---|---|
| Partner-Sourced Pipeline program, one SDR included | From $50,000 a quarter |
| GTM motion (planning price) | About $12,500 each, so four fill the $50,000 |
| Second SDR | $10,000 a month |
| Enrichment | Always its own line |
We contract a quarter at a time, with no long-term lock-in.
Partners fund programs, not tools. So programs are often funded by partners through market development funds (MDF) or co-funding. Partners can cover all or part of a program, so it could cost you $0. Our MDF guide covers how that works.

Frequently asked questions
What is SDR as a service?
It’s sales development sold as a monthly service instead of a hire. A provider supplies the SDRs, tools and management. With Forecastable, the SDR comes inside a partner program and calls as your partner.
What’s the difference between an outsourced SDR and an outsourced BDR?
Mostly the title. Some companies use BDR for outbound and SDR for inbound follow-up, but many outsourced providers use the two interchangeably.
Is an outsourced SDR cheaper than hiring one?
Compare cost per SQO, not salary. After all, an in-house hire takes about three months to ramp, per The Bridge Group, before you see real output. An outsourced SDR starts sooner, and partner funding can cover part of the cost.
Do I get my own SDR?
Yes. Each Partner-Sourced Pipeline program includes one SDR making about 1,000 cold calls a month across your GTM motions. With three to five motions, we prioritize which ones get calls, or you add a second SDR.
Who handles replies to the outreach?
Real people on our campaign operations team handle every reply and follow-up. AI audits and reports on the work, and you see all of it through the Forecastable MCP.
How many calls does an SDR make a month?
We plan on about 1,000 calls a month per SDR. On industry averages, about 1 in 10 dials reaches a live conversation.
Can I add more SDRs?
Yes. A second SDR is $10,000 a month and doubles your calls to about 2,000 a month.
Are SDRs included in Accelerate My Partner Program?
No. SDRs are only in Partner-Sourced Pipeline. Accelerate, webinars and events don’t include an SDR.
What’s the bottom line?
An outsourced SDR who calls as you builds sales-sourced pipeline. But an outsourced SDR who calls as your partner builds partner-sourced pipeline. As a B2B partnerships agency, we run that second kind, with real human SDRs on the phones. And when you need the first kind, we’ll tell you.
Forecastable is an independent third-party professional services company. Our evaluations of other vendors are based on publicly-available information as of November 2026 and our own client experience.
