What they charge

Pricing models used by the 24 of 24 sdr agencies that disclose pricing:

  • Custom monthly retainer for outsourced sales development, sold in tiered team-size packages by number of BDRs (Start = 1 BDR, Grow = 2 BDRs, Scale = 3 BDRs). The engagement appears to be a done-for-you outsourced SDR/BDR program rather than pay-per-lead or pay-per-appointment pricing.
  • Custom monthly retainer tied to dedicated SDR capacity and campaign scope, rather than per-lead or per-appointment pricing. Leadium explicitly describes pricing as a monthly retainer that includes research, data, messaging, infrastructure, and reporting, with month-to-month engagements and optional pilot starts.
  • Custom outsourced sales engagements with a hybrid structure: recurring monthly billing for dedicated sales team/services, plus in some cases performance-based billing tied to held appointments; also a one-time optional data fee for lead-list building.
  • Custom quote overall, with a mix of fixed-fee consulting/project packages, lead-volume-based data services, salary-percentage recruiting fees, and recurring retainer/subscription engagements for broader SDR / GTM programs. AltiSales also appears to sell larger ongoing programs such as retainer-based SDR/GTM engagements, but public pages do not publish those retainer amounts.
  • Custom quote with flexible engagement structures: retainer-based, outcome-based, or hybrid. MarketStar also explicitly supports performance pricing models including base + commission, base + bonus, and pay-for-performance tied to metrics such as closed revenue, SQOs, or MQLs.
  • Custom-quoted B2B lead generation / outsourced SDR engagement with a monthly-style managed-service structure, backed by an SQL/performance guarantee; likely hybrid retainer + performance guarantee rather than pure pay-per-lead, because MarketJoy says it offers flat rates on plans, guarantees SQL delivery, and continues working at no cost if results are missed.
  • Custom-quoted monthly outbound lead generation / sales outsourcing engagement, with a stated month-to-month contract structure for its outbound package. Public evidence points to recurring service engagements rather than fixed self-serve pricing, and Clutch reviews show many engagements landing in project-spend bands.
  • Custom-quoted monthly outsourced SDR / appointment-setting service for B2B outbound prospecting. Evidence supports a retainer-style engagement rather than published package pricing: a Clutch client described a 5-month engagement totaling about $32,000 for end-to-end outbound SDR work, implying an ongoing monthly service model.
  • Custom-quoted monthly retainer for outsourced SDR / appointment-setting programs, with publicly listed starting pricing for 4-week engagements. SalesRoads sells at least two named service lines—Full SDR Appointment Setting and Market Research Lead Generation—both starting at the same 4-week retainer price. Third-party listings also indicate a 3-month pilot followed by month-to-month billing.
  • Custom-quoted monthly retainer for outsourced SDR / lead generation packages (Fractional SDR, Full-Service SDR, and Growth), with prepaid monthly billing. Engagements are package-based rather than published per-lead or per-appointment pricing.
  • Custom-quoted monthly retainer for outsourced SDR / sales development services, typically sold as dedicated SDR or FTE resources with meeting-booking / pipeline-development deliverables; also offers a "Try + Hire" model where clients can convert consultants to employees during an engagement.
  • Custom-quoted outsourced SDR / appointment-setting engagements. The evidence points to a monthly service model for fully managed outbound SDR programs, plus a flexible staffing-style "Hire SDRs" offer; Whistle itself says pricing varies by scope depending on whether you hire SDRs, run full-service outbound, or need RevOps support.
  • Custom-quoted outsourced SDR / lead-generation engagement that appears to be sold as a managed service, likely monthly retainer and/or scoped project work rather than fixed public packages. The company markets dedicated lead researchers and SDRs embedded into the client's sales process, with no public self-serve pricing.
  • Custom-quoted outsourced SDR / sales development engagement, primarily sold as a monthly retainer or project-based program. Operatix describes programs as tailored to business goals, SDR resource requirements, target regions, sales-cycle length, deal value, and desired pipeline; third-party directory/category sources also classify the firm under monthly retainer / project-based billing.
  • Flat monthly retainer priced by dedicated staffing level (half-time or full-time specialist), sold as outsourced revenue-team capacity rather than pay-per-lead. EBQ’s own site says projects are billed based on how many half-time/full-time employees you partner with, and many engagements include a Revenue/Business Consultant, a project manager per service, and tool access.
  • Flat-rate monthly retainer for outsourced SDR / sales development services, sold in tiered packages. Engagements can be phone-only or phone+email, with US-based or Philippines-based SDR options; SalesHive also describes the service as an all-in managed program rather than pay-per-meeting.
  • Hybrid custom pricing. Martal sells managed B2B lead generation / sales outsourcing as a monthly flat-fee subscription after a 3-month pilot, and it also sells an AI sales platform in tiered plans with pricing gated behind quote requests.
  • Hybrid custom quote model with multiple engagement types: (1) performance-based pay-per-held-qualified-meeting under "Demand Held," (2) dedicated outsourced FTE/BDR capacity under "Demand FTE," and (3) event-based/virtual lunch meeting programs under "Demand 'n' Lunch." DemandZEN also charges a one-time onboarding fee across plans.
  • Hybrid monthly retainer with packaged service tiers. Public evidence shows fixed monthly packages for outbound sales-team augmentation and separate fixed monthly inbound/SEO packages, with custom quotes for needs outside listed tiers.
  • Hybrid pricing across multiple offers: (1) monthly retainer for fully managed prospecting / outsourced BDR services, (2) per-account SaaS-style subscriptions for AI digital outreach sold monthly or annually, often with a one-time onboarding/setup fee, and (3) per-event / per-data-package pricing for add-ons like webinars and data.
  • Hybrid pricing: a one-time GTM setup fee plus a monthly platform/managed-execution retainer, with optional at-cost SDR staffing and a variable pay-per-held-meeting commission. CIENCE also markets month-to-month service with custom ROI-based per-meeting fees.
  • Hybrid/custom outbound sales prospecting pricing. Public evidence shows (1) a flat monthly retainer for a managed outbound prospecting program / monthly retained per agent model, and (2) a newer pay-per-lead / pay-for-performance option with onboarding and program-management costs still applying.
  • Multiple models depending on service line: (1) performance-based recruitment billed as 1.5% of salary per month for 12 months, with billing stopping if the hire leaves; (2) month-to-month monthly retainers for legacy/outbound services such as cold email, LinkedIn outbound, sales management, and full-suite SDR services; and (3) custom/fractional leadership engagements with flexible scope, typically 3-6 months.
  • Primarily hourly, delivered as an outsourced outbound sales / lead generation engagement; third-party comparisons also describe it as an hourly or project-based retainer. The agency site itself does not publish prices and appears to have been redirected to MarketStar after acquisition.
