Vendor comparison

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

Source review: 9 September 2026 // Published by ReplyLead // Editorial standards

The short answer: an outsourced SDR company handles an agreed part of prospecting, outreach, qualification and meeting booking. The right choice depends on which work you need to transfer. Compare twelve providers below, including staffed services, channel specialists and an AI platform. Use their published prices as starting points, then compare the full cost per held, qualified meeting under the same assumptions.

Publisher disclosure. ReplyLead sells outbound services and appears in this comparison. This is research into vendor-published offers, not hands-on testing of twelve providers or an independent ranking of their results. Order is not a performance ranking. Fit assessments are our analysis of the stated scope; confirm delivery evidence and written terms before buying.

Turn a quote into a cost per outcome

Enter a monthly fee, expected held qualified meetings and your own sales assumptions. The calculator shows fee-only cost per meeting and revenue coverage. It does not infer meetings from email volume or predict a provider’s results.

The quote you have been given

Monthly fee quoted $5,000Recurring fee only. Add setup, usage and variable fees to your total-cost comparison.

Expected held qualified meetings a month 15Use meetings actually attended and accepted. Convert booked meetings using your own show and acceptance rates.

Your first-year contract value $25,000Revenue per new customer, not gross profit or immediate cash received.

Your close rate on held qualified meetings 20%Use a comparable cohort and allow for your sales cycle; this is an assumption.

Monthly outbound emails for the ReplyLead reference 25,000An independent input, used only to look up ReplyLead’s published infrastructure tier.

$333Fee-only cost per held qualified meeting

1.3%Close rate needed for first-year revenue to cover this monthly fee only

25,000Monthly outbound emails, as you entered them

$2,023ReplyLead infrastructure tier for that volume: 40% of the entered fee. Revenue share is additional.

Check the arithmetic. Fee-only cost per held meeting = $5,000 / 15 = $333. Revenue-coverage close rate = $5,000 / (15 × $25,000) = 1.3%. The entered close rate would associate $75,000 in first-year contract revenue with this month’s meeting cohort, if those assumptions hold. This is not monthly cash receipts. Separately, 25,000 emails falls in ReplyLead’s $2,023 infrastructure tier: 40% of the entered fee. See the pricing model and all seven tiers.

Use the right denominator and cost base. Revenue coverage is not profit break-even: it excludes setup, sales labour, gross margin, churn, collections and any commission or revenue share. The ReplyLead tier is a separate price reference, not another vendor’s internal cost, margin or required sending volume. Phone-led programs may not need it at all. Email volume does not establish a meeting commitment.

A quote that looks like $333 per meeting can cost $500 per held meeting

Illustrative example, not a vendor forecast: a $5,000 monthly retainer promises 15 booked meetings. At an assumed 80% show rate, 12 are held. Assuming all 12 meet your qualification criteria, fee-only cost is $5,000 ÷ 12 = $417 per held meeting, rounded. Over three months, a $3,000 setup fee plus $15,000 in retainers divided by 36 held meetings is $500 each. If some held meetings are rejected, accepted-meeting cost rises further.

Compare offers over the same delivery period. A fee of $9,950 every four weeks annualizes to $129,350 over 52 weeks, versus $119,400 for twelve calendar-month invoices at the same nominal fee. This is billing arithmetic, not a statement about a provider’s minimum contract. For revenue share, add the agreed share of attributable revenue over that same period before deciding which proposal costs less.

The twelve, compared

Scope first, price second. Seven providers below publish a numeric price for at least part of their offer. 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.

Check the evidence before signing

Use these five checks on every shortlisted provider, including ReplyLead. Score the evidence in your written proposal: 1 = missing, 3 = partial, 5 = clear and complete; use 2 or 4 for intermediate cases. These equal-weight scores organize follow-up questions. They do not measure service quality or predict ROI. A custom quote can score as well as a public price, and a retainer can score as well as revenue share.

Substantial documentation is missing

Collect the missing scope and terms before making a decision. This score describes the evidence you have, not the competence of the provider.

All three bands are listed because JavaScript is not running. Add your five scores and read the band your total falls in.

One check that does not fit a slider: ask who will actually staff your account — named people, not a pool — and what happens to that team if the provider is acquired or restructures. This category consolidates regularly, and an account team can change without your input mid-contract. Get continuity in writing alongside the qualification bar.

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.

On a small screen, swipe the table sideways to compare all columns.

Decision	Outsourced service	In-house team
Time to productive outreach	Ask for setup, training and launch milestones; vendor availability and your inputs determine ramp.	Include recruiting, onboarding, tool setup and learning your market.
Total cost	Setup + recurring and variable fees + internal management and closing time.	Compensation + hiring + benefits + tools/data + management + ramp and vacancy costs.
Control and learning	Specify approval rights, reporting access, experiment history and handover.	You manage priorities directly; retain usable documentation when people leave.
Capacity changes	Check notice periods, minimum commitments and how staffing changes affect continuity.	Hiring and utilization determine how much capacity is productive.
When to consider it	Defined offer and ICP, enough reachable buyers, a clear scope to transfer and someone to handle sales calls.	Sustained workload and the management capacity to recruit, coach and retain the role.

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.

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

Provider by provider

Each profile separates the published offer from our interpretation of where it may fit. No provider is awarded a performance score.

ReplyLead

Published offer: Managed cold email; your team closes. $2,023–$44,090/month infrastructure, plus negotiated revenue share. Seven volume tiers; the share, attribution window and exit terms need a written agreement.

When to consider it: Consider when you have a proven B2B offer, capacity to take meetings and margins that can support revenue share.

Tradeoff: The infrastructure fee remains when no deals close. A successful campaign can cost more in total than a fixed retainer; model the share over your sales cycle.

Ask before signing: What revenue is attributable, for how long, and what happens to fees, domains and campaign data after termination?

ReplyLead: official offer and scope · reviewed 9 September 2026.

CIENCE

Published offer: GTM setup and managed growth; SDR capacity separate. $7,499 first month for setup + strategy + platform; SDR costs additional. $5,000 setup + $2,000/month strategy + $499/month platform. SDR capacity, onboarding and meeting fees are separate.

When to consider it: Consider when you need the operating system and campaign management as well as a route to additional SDR capacity.

Tradeoff: The core package is not an all-in staffed SDR quote. Combining its components with staffing changes both startup and ongoing cost.

Ask before signing: Itemize SDR level, region, onboarding, meeting fees and credit usage alongside the core plan.

CIENCE: official offer and scope · reviewed 9 September 2026.

Belkins

Published offer: Managed appointment setting. From $5,000/month. Published starter references 1,500 leads/month and 100 guaranteed appointments/year; scope is customized.

When to consider it: Consider for a managed appointment-setting brief where you want to agree audience, outreach channels and qualification up front.

Tradeoff: An annual appointment figure is not a monthly delivery commitment. The starter price does not establish the cost of your exact market or scope.

Ask before signing: Which appointments count, how are no-shows or rejected meetings treated, and when must the annual volume be delivered?

Belkins: official offer and scope · reviewed 9 September 2026.

Cleverly

Published offer: LinkedIn lead generation at the cited entry price. From $397/month for LinkedIn lead generation. This entry price is channel-specific; request a separate scope for a broader SDR service.

When to consider it: Consider a LinkedIn-focused test when your buyers use that channel and you can handle conversations and follow-up.

Tradeoff: A LinkedIn campaign is not equivalent to a dedicated SDR running calls, email, qualification and booking. Compare responsibilities before comparing fees.

Ask before signing: Who works replies and qualifies prospects, which account is used, and what additional channels or staffing cost extra?

Cleverly: official offer and scope · reviewed 9 September 2026.

OutreachBloom

Published offer: Managed cold-email outreach. From $2,400/month. The cited starting price is for cold email; confirm list, infrastructure, reply-handling and booking scope in your quote.

When to consider it: Consider for an email-led campaign when you want a managed service with a visible starting budget.

Tradeoff: A channel-specific package does not tell you whether calling or LinkedIn is needed for your market, or whether your target volume fits the entry scope.

Ask before signing: What monthly capacity, qualification definition, excluded work and cancellation terms apply to this quote?

OutreachBloom: official offer and scope · reviewed 9 September 2026.

SalesHive

Published offer: Managed sales development; US and offshore options. Custom quote on the reviewed pricing page. Phone-only and phone + email options; monthly or annual plans. Published cancellation notice runs through the end of the next billing month.

When to consider it: Consider when calling is central and you want to compare staffing location, channel mix and managed delivery.

Tradeoff: A monthly plan can still leave a notice-period liability. Platform-only access and a fully managed program are different purchases.

Ask before signing: Which delivery team and channels are included, and what is the final invoice date if notice is given on a specific day?

SalesHive: official offer and scope · reviewed 9 September 2026.

Martal Group

Published offer: Outsourced sales development; broader sales options. Custom quote. Tier 1A outbound: flat monthly fee, three-month pilot. Higher sales tiers show a four-month pilot and fee + commission.

When to consider it: Consider when you want to choose between prospecting support and a broader sales role rather than assume every package ends at booking.

Tradeoff: Pilot duration and commission exposure depend on tier. A production-funnel example is not your contracted delivery promise.

Ask before signing: Which tier owns discovery and later follow-up, and what minimum pilot spend and commission survive the pilot?

Martal Group: official offer and scope · reviewed 9 September 2026.

SalesRoads

Published offer: Outsourced SDR and appointment setting. From $9,950 per four weeks. Four-week billing is not calendar-month billing; confirm onboarding, minimum commitment and cancellation.

When to consider it: Consider for a staffed SDR brief when you need a published starting point to assess budget before scoping delivery.

Tradeoff: A four-week price understates the annualized budget if it is multiplied by twelve. Staffing and account scope still require a proposal.

Ask before signing: What does each four-week period include, when does paid delivery begin, and how many periods are committed?

SalesRoads: official offer and scope · reviewed 9 September 2026.

AiSDR

Published offer: AI sales platform with optional managed services. Solo $250, Explore $900, Scale $2,500/month. Explore and Scale show quarterly commitments. Managed Explore: +$149/campaign; fully managed Scale: +$2,500/month.

When to consider it: Consider when you want to operate an AI-assisted outbound workflow or explicitly add management to a platform subscription.

Tradeoff: The entry subscription is not a like-for-like staffed SDR service. Management, capacity and contract duration change the effective price.

Ask before signing: Who approves targeting and messaging, handles exceptions and replies, and owns qualification under the selected plan?

AiSDR: official offer and scope · reviewed 9 September 2026.

memoryBlue

Published offer: Sales development and broader integrated sales services. Custom quote; no fixed figure on the cited services page. Scope can extend beyond SDR work; ask for an itemized proposal and delivery responsibilities.

When to consider it: Consider when the brief includes sales development alongside needs such as sales talent, training or broader sales support.

Tradeoff: A broad services menu does not establish how much dedicated prospecting time your account receives. Separate the SDR deliverable from adjacent work.

Ask before signing: What team allocation, manager involvement, ramp milestones and handoff standards are committed to your account?

memoryBlue: official offer and scope · reviewed 9 September 2026.

Callbox

Published offer: Managed multichannel B2B lead generation. Custom quote; no fixed figure on the cited page. Confirm channel mix, target-account coverage, delivery definition and subscription scope.

When to consider it: Consider when you want a coordinated multichannel campaign rather than an email-only or software-only purchase.

Tradeoff: Aggregate lead volume can conceal differences in channel contribution and qualification. Require one reporting definition across the channels you buy.

Ask before signing: Can reporting separate sourced contacts, responses, accepted leads, booked meetings and held meetings by channel?

Callbox: official offer and scope · reviewed 9 September 2026.

MarketStar

Published offer: Sales outsourcing across broader revenue functions. Custom quote; no fixed figure on the cited page. Scope can include sales, partner/channel and customer-growth functions; isolate the SDR component.

When to consider it: Consider for a broader enterprise outsourcing brief involving multiple revenue functions or a larger operating model.

Tradeoff: A wide outsourcing scope can make a simple per-meeting comparison misleading. Evaluate governance, implementation and the parts your team still owns.

Ask before signing: What is the SDR-specific cost and service level, and how does it connect to the other outsourced functions?

MarketStar: official offer and scope · reviewed 9 September 2026.

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

We reviewed the twelve linked official offer 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 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.

Common questions

What does an outsourced SDR company actually do?

It handles an agreed part of targeting, prospecting, outreach, qualification and meeting booking. Some offers are software or single-channel campaigns; others include staffed multichannel delivery. Your proposal should name who handles replies, CRM entry, reschedules and sales follow-up.

How much do outsourced SDR companies cost?

The cited offers range from a $250/month AiSDR platform tier and $397/month Cleverly LinkedIn service to staffed and managed programs with larger or custom fees. These are different scopes. Examples include Belkins from $5,000/month and SalesRoads from $9,950 per four weeks. Add setup, usage, staffing and variable fees before comparing.

Is outsourcing cheaper than hiring an SDR?

It depends on scope, utilization, ramp and management needs. Compare the full outsourced contract plus your internal time against compensation, benefits, hiring, tools, data and management for an in-house role over the same period.

Does a low price mean a worse program?

Price alone does not establish delivery quality. A low entry price may cover a channel or platform rather than a staffed function. Check scope, relevant evidence, qualification and the complete contract cost.

Which outsourced SDR company is best for enterprise?

MarketStar is worth investigating for a broader enterprise sales-outsourcing brief. For other scope combinations, investigate memoryBlue, Martal and the managed SDR providers in the table. Published scope supports a shortlist, not a claim that one provider delivers the best results.

Which SDR outsourcing companies publish prices?

On the pages reviewed on 9 September 2026, ReplyLead, CIENCE, Belkins, Cleverly, OutreachBloom, SalesRoads and AiSDR publish a numeric price for at least part of an offer. SalesHive, Martal, memoryBlue, Callbox and MarketStar require a scoped quote on the cited pages. Entry prices do not necessarily cover the complete service.

Why is ReplyLead first on this list?

ReplyLead publishes this comparison and is a commercial participant. The order is not a performance ranking. We have not hands-on tested the other providers. Apply the same evidence, cost and contract checks to our proposal as to every alternative.

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.
