Best outsourced SDR companies and SDR outsourcing firms, priced per outcome

The twelve, compared

Scope first, price second. Seven providers below publish a numeric price for at least part of their service. Five require a quote on the pages reviewed. A published platform or channel-entry price is not a complete staffed SDR budget. Amounts use the vendors' dollar notation; confirm currency, tax and current terms in writing. Source review: 9 September 2026.

SDR outsourcing pricing: what outsourced SDR companies cost in 2026

Outsourced SDR cost depends on what you are buying: a software seat, a single-channel campaign, SDR as a service (a dedicated or fractional rep billed per month or per four weeks) or a managed programme. On their own pages, read on 24 September 2026: ReplyLead publishes infrastructure from $2,023 a month plus an agreed share of closed revenue; Cleverly's LinkedIn service starts at $397 a month; AiSDR's platform runs $250, $900 or $2,500 a month; OutreachBloom's cold email starts at $2,400 a month; CIENCE charges $7,499 in the first month ($5,000 setup, $2,000 strategy and $499 platform) with SDR capacity priced separately; Belkins' average starter price is from $5,000; and SalesRoads charges $11,950 per four weeks for one dedicated SDR, about $12,946 a month. SalesHive, Martal Group, memoryBlue, Callbox and MarketStar quote on request.

SDR as a service: what a dedicated rep costs

ReplyLead does not sell SDR seats: it runs the outbound itself, on infrastructure from $2,023 a month plus a share of closed revenue. SalesRoads publishes one example of SDR as a service: $11,950 per four weeks for one dedicated SDR and $16,750 for two. Four-week billing means 13 invoices a year, $155,350 for one SDR at the listed rate; SalesRoads says a dedicated SDR team launches in 15 business days and recommends its 12-week go-to-market lab before making any decisions. CIENCE lists SDR rates from $1,500 (Level 1, offshore) to $6,500 (Level 3, US), with no billing period stated beside them, and SalesHive and Martal Group quote SDR programmes on request. Convert every option to cost per held, qualified meeting with the quote decoder above.

Outsourced SDR vs in-house SDR: which fits your team?

Outsourcing changes who runs the work; it does not remove the need for an owner on your side. In-house hiring gives direct management of the role but adds recruiting, ramp and ongoing coaching. Compare the same channels, productive capacity and qualification standard.

If the ICP is still unsettled or your team cannot follow up promptly, buying more meetings may magnify that bottleneck. Use the SDR cost calculator with your own assumptions and compare the job-by-job outsourced scope.

How to choose an outsourced SDR company

Build a shortlist around the work you need done, then request comparable evidence. The fit suggestions in the provider profiles are scope-based editorial judgments, not verified performance awards. If you are still choosing between SDR staffing and other delivery models, the B2B lead generation company comparison maps 14 providers to six models first.

1. Define the buyer and meeting. Put target accounts, geography, personas, exclusions and acceptance criteria in the brief.
2. Choose the operating scope. Separate platform access, a single-channel campaign, managed SDR work and full-cycle sales.
3. Normalize the budget. Request setup, billing cadence, minimum term, usage, commissions and internal time over one shared evaluation period.
4. Name the account team. Ask about dedicated versus shared capacity, manager coverage and replacement arrangements.
5. Inspect relevant evidence. Ask for a comparable client reference and a redacted report showing denominators, dates, held meetings and accepted opportunities.
6. Document channel access. Establish approval rights, infrastructure responsibilities and how brand or account issues are handled.
7. Map the handoff. Decide who handles replies, reschedules, CRM entry, follow-up and qualification disputes.
8. Set a review window. Allow for ramp and your sales cycle. Review held-meeting quality and opportunity progression before scaling spend.
9. Agree the exit. Calculate notice-period exposure and specify data, assets and account access after the engagement.

Evidence and comparison method

What our operating data can establish

ReplyLead's published cold-email dataset covers 429,763 sends across 115 campaigns and seven client programs. In the subset of 81 campaigns that contacted at least 500 leads, the median campaign reply rate was 2.12% per contacted lead. Reply counts include automated replies; this is not a positive-reply, meeting or close rate. Read the linked methodology and limitations before using it as context.

Our separately reported client case studies describe individual engagements. They are first-party evidence, not independent audits or forecasts for your campaign. Neither dataset establishes competitors' conversion rates, required email volume or internal costs.

How this comparison was produced

Scoring model this page uses: we do not assign point scores or a best-overall rank. Each provider is described on the same published facts: service model, displayed price or quote status, stated buying constraint, and the official source with its check date. Fit labels are editorial. A dedicated SDR seat, a retainer appointment-setting programme and a revenue-share outbound programme are different purchases. For the revenue-share / no-retainer model, see also no-retainer lead generation agencies.

We reviewed the twelve linked official pages on 9 September 2026. The table records published starting prices, billing units and scope boundaries. "Custom quote" refers to the cited page reviewed, not proof that no price exists elsewhere. We did not purchase or test the competing services, audit their customer results or independently verify their delivery claims. Vendor terms can change; use a written proposal for a purchase decision.

ReplyLead publishes this comparison and sells the service. ReplyLead is the publisher and a provider on the list. Research and drafting used automated assistance to organize source material and check arithmetic. The fit assessments are editorial interpretations of the published scopes. The quote example is illustrative and the checklist is an unvalidated decision aid; neither is a provider rating. Learn about ReplyLead and its founder and our editorial standards.

What would change a shortlist?

A reference from your market, a clear sample report and a complete scope can strengthen a candidate. An unclear meeting definition, material unquoted fees or a delivery model you cannot support should prompt more diligence. Published price alone, a vendor's testimonial count or a high checklist total does not resolve those questions.

When this comparison does not apply

• You want software, not a service. AiSDR is the one platform here; compare self-serve tools on their own terms.
• You need closing or account management. MarketStar, memoryBlue and Martal Group's upper tiers extend beyond SDR work; compare them with the sales outsourcing guide.
• You would rather hire in-house. Model the in-house cost first with the SDR cost calculator.
• You buy outside the US. The figures are the US-dollar prices on each provider's page; confirm currency and tax.
• You are reading this months from now. SalesRoads moved its entry price from $9,950 to $11,950 between July and September 2026. Re-check every provider's own page before you sign.

In short: we did not buy or test these services; every provider fact comes from the provider's own published pages on the dates shown.

Where to go next

For what the SDR function looks like as a system rather than seats, see outsourced sales development; for the model landscape one level up - inside sales, full-cycle, management - see sales outsourcing. For the job-by-job scope of what an agency takes on, and an eight-outcome tool that will sometimes tell you not to outsource at all, see done-for-you outbound. For what the category charges generally and the full tier table, see what a cold email agency costs. For the commercial models side by side, see pay per appointment versus retainer and pay per lead agencies, who operates lead generation with no retainer. For the underlying research and everything these datasets deliberately do not report, see cold email benchmarks. If you sell software rather than services, the same choice narrowed to that market is on outbound agency for B2B SaaS. And because every provider on this page is ultimately judged on whether their mail arrives, it is worth knowing which inboxes you are sending to: we classified 9,058,780 business domains by receiving provider in who actually receives B2B email. Our own terms are on pricing.
