The best B2B cold calling outsourcing companies solve different problems. Some manage your entire prospecting program. Others supply dedicated callers who follow your sales process. Choosing between them starts with knowing which responsibility you want to hand over.
If your business needs targeting, scripts, coaching, and campaign management, compare agencies on that complete scope. If you already have a sales leader and a working playbook, compare dedicated staffing options on candidate quality, working hours, and ongoing support.
We built this shortlist to help you decide: below, you’ll find seven providers, what each is best suited for, current pricing information where available, and the questions that matter before you commit.
How We Ranked These Cold Calling Companies
We selected these providers based on their published service scope, calling capabilities, pricing transparency, management responsibilities, and suitability for different B2B sales needs.
This is an editorial shortlist, not a performance ranking. The companies are presented from managed outbound services to dedicated staffing, so their position does not indicate superior results. We include Hire Overseas because we offer dedicated offshore callers, and we haven't independently tested every provider.
Compare the Best B2B Cold Calling Outsourcing Companies
Compare the responsibilities included in each proposal before comparing the price. A dedicated caller and a managed outbound department are different purchases.
Pricing reflects the pages reviewed, not a binding offer. Confirm scope, billing periods, contract terms, and exclusions in writing.
1. SalesRoads: Best for a Managed Calling Program With Coaching and Research
SalesRoads is best for businesses that want a provider to supply SDRs, prospect research, playbook development, and ongoing sales coaching.
What You Get
Its program combines dedicated SDRs with strategy, research, performance coaching, and optimization support. It includes calling and personalized email, plus CRM integration and a performance dashboard.
Consider this when your closers need opportunities, and your business needs operational support around the caller.
Pricing and What to Confirm
The two-SDR option costs $16,750 per four-week engagement, or $8,375 per rep. Confirm the current single-SDR starting price in your proposal. Four-week billing produces 13 periods over 52 weeks, so compare annual costs against calendar-month proposals.
SalesRoads advertises cancellation at any time with no long-term commitment. Confirm the notice and billing terms in your agreement.
Ask how qualification criteria become call instructions, who approves targeting changes, and how unsuccessful meetings are reviewed. The practical trade-off is paying for a broader support structure when you may already have some of that capability internally.
2. SalesHive: Best for Comparing US and Offshore Managed SDR Options
SalesHive is best for businesses comparing US-based and offshore SDR delivery within a managed outbound service.
What You Get
Its managed plans combine dedicated SDRs, a strategist, prospect data, tools, and reporting. The published options distinguish phone-only coverage from phone-and-email programs, with US-based and offshore team choices.
Keep your target audience and qualification requirements consistent when comparing team configurations and channels.
Pricing and What to Confirm
Current managed plans are custom quoted. Pricing depends on team location, channels, team size, and activity scope. Month-to-month and annual options are available, and the pricing page states there are no setup fees.
After launch, month-to-month cancellation requires written notice, with outreach and billing ending at the end of the next billing month. Confirm caller location, working hours, and CRM reporting. Quoted volumes are daily touches, so ask how many are calls.
3. Callbox: Best for Multilingual Prospecting Across Several Markets
Callbox is best for businesses that need coordinated prospecting in multiple languages, not a single English-language calling campaign.
What You Get
Its multilingual SDR offering brings research, phone prospecting, email, LinkedIn outreach, qualification, and campaign management into one program. Published language options include Spanish, Portuguese, Mandarin, Thai, Vietnamese, Filipino, and Bahasa. Confirm additional language availability when scoping your campaign.
The useful distinction is coordinated market coverage. If your expansion plan involves several countries, ask whether one management structure can maintain consistent qualification while adapting the conversation to each market.
Pricing and What to Confirm
Request a proposal specifying languages, caller capacity, markets, and channels. The multilingual service page does not provide a fixed package price.
Confirm actual availability for each language and calling window. Request separate reporting by market so stronger results in one country do not hide weak performance elsewhere. Your evaluation should include language-specific call samples and the handoff process for prospects who prefer to continue in that language.
4. Belkins: Best for Combining Calling With Broader Outreach
Belkins is best for businesses that want calling coordinated with other prospecting channels, including follow-up informed by engagement signals.
What You Get
Its service supports standalone cold calling and intent-based calling informed by email or LinkedIn engagement. Calling packages include a dedicated agent, manual lead research, tailored scripts, 24/7 reporting, appointment scheduling, and no-show recovery.
Evaluate how the channels work together if your prospects need several touches before accepting a conversation.
Pricing and What to Confirm
The calling page publishes an average starter price of $5,000, with a customized proposal. Confirm the billing period and scope.
The broader Growth retainer includes intent-based calling but excludes standard cold calling and voicemails. Growth Plus includes both. The small-business package excludes calling and is delivered through partnering agencies in the Belkins ecosystem. Confirm the package and delivery team before comparing quotes.
5. memoryBlue: Best for Technology Businesses Needing Managed SDR Capacity
memoryBlue is best for B2B technology and services businesses that want dedicated SDRs supported by an external management structure.
What You Get
For complex offers, use your evaluation to test how the assigned team learns the product and identifies a credible sales opportunity. Technical vocabulary alone does not establish useful qualification.
Pricing and What to Confirm
Pricing is customized, with retainer and performance-based engagement options described on the service page.
Ask where the SDR’s responsibility ends, and your account executive’s begins. Confirm data access and transfer rights in the agreement rather than assuming every record is automatically yours. The fit depends on whether you need externally managed prospecting capacity and can support the sales conversations that follow.
6. Martal Group: Best for Sales Support Beyond Initial Appointments
Martal Group is best for businesses evaluating outsourced sales support that may extend from lead generation into customer onboarding and account management.
What You Get
Tier 1 covers lead generation, including targeting and outbound calls. Tier 2 adds sales support through deal closure and customer onboarding. Tier 3 adds post-sale account management.
Consider these tiers when your sales gap continues after the first meeting.
Pricing and What to Confirm
Pricing is customized. Tier 1 outbound uses a flat monthly fee; Tiers 2 and 3 combine a monthly fee with sales commission. Confirm commission rates and payment triggers.
Ask Martal to confirm whether your proposal requires a three-month Tier 1 outbound pilot or a four-month Tier 2 or 3 pilot, and what cancellation terms apply afterward.
Confirm who can discuss pricing, negotiate terms, and make commitments to prospects. Broader sales support needs clear boundaries around commercial authority and customer ownership.
7. Hire Overseas: Best for Owning Your Outbound Function With a Dedicated Caller
What You Get
Your caller works exclusively for your company. We can match experience to your CRM and calling workflow, while your team sets the offer, qualification rules, and sales handoff. This suits businesses with someone ready to direct outbound execution.
Pricing and What to Confirm
Our dedicated cold callers typically cost 2,400-3,400 monthly, including talent, HR, payroll, and compliance. Quotes vary with seniority, tools, and working hours.
We offer month-to-month terms, a 14-day money-back guarantee, and a forever replacement policy. Scope list building, coaching, software, and campaign strategy explicitly when planning the role. Dedicated staffing still needs a clear sales owner inside your business.
How to Choose a B2B Cold Calling Company
Shortlist providers against the work your business needs done. These checks help you compare proposals without letting activity promises or a low headline price drive the decision.
Step 1: Assign Ownership Before Comparing Fees
Write down who will own targeting, contact data, script updates, coaching, and meeting acceptance. Then match those responsibilities to each proposal. A startup without an SDR manager may need campaign leadership, while an established sales team may mainly need another capable caller.
Step 2: Compare Cost per Qualified Meeting Held
Use a consistent calculation: total program cost divided by meetings held that satisfy your agreed criteria. Include setup fees, software, data, incentives, and internal management costs where applicable.
For example, a hypothetical $6,000 program producing 12 qualified meetings held costs $500 per meeting. Booking 20 meetings does not change that calculation if only 12 attend and qualify. Track accepted opportunities and eventual revenue alongside this metric.
Step 3: Read Appointment Guarantees Closely
When comparing pay-per-appointment vs retainer cold calling, define the billable outcome. Establish acceptable companies, job titles, business needs, exclusions, and attendance requirements. Confirm how you handle duplicates, cancellations, no-shows, and disputed meetings.
A guaranteed appointment count needs a contractual definition. It does not establish that those appointments will become sales-qualified opportunities or paying customers.
Step 4: Inspect the Workflow and Exit Terms
Request a demonstration of how calls, notes, follow-ups, and meetings enter your CRM. Confirm access to recordings, scripts, suppression records, and exports, including restrictions when the engagement ends.
Ask whether calls are human-led, AI-assisted, or conducted by an automated voice system. Review the proposed workflow against the rules in your target markets, and assign responsibility for calling permissions, opt-outs, recording, and complaints. Staffing compliance and outbound campaign compliance need separately defined responsibilities.
Build Your Outbound Team Around the Sales Conversations You Need
The best cold calling partner should close a specific gap in your sales operation. Choose a managed campaign when you need targeting, messaging, and daily management. Choose a dedicated caller when your team has a clear process and needs consistent execution. Compare both on qualified conversations, meetings held, and opportunities your sales team accepts.
A successful engagement should make outbound easier to manage. You should know who represents your business, how you qualify prospects, and what happens after someone expresses interest. Clear reporting and regular feedback help you improve targeting, strengthen messaging, and decide when to add capacity.
We build your search around those requirements. Tell us who you sell to, the objections your caller needs to handle, your budget, and the hours your buyers answer. We’ll find and vet candidates, then help you assess them directly. We handle recruiting, HR, payroll, and staffing compliance so you can focus on sales direction and performance.
