You’re evaluating Outbound Sales Pro and Belkins side by side to find your next outbound sales partner, well past the stage of casually Googling appointment-setting agencies. You’ve read a Belkins review or two, and now you’re asking a sharper question: Is Belkins worth it against Outbound Sales Pro for a team your size?
This Outbound Sales Pro vs Belkins comparison gives you four things: a side-by-side snapshot table, a transparent pricing breakdown, a week-by-week onboarding walkthrough, and a straight answer on which agency fits your team. Belkins does not publish its rates, so every price in this piece is labeled as either confirmed or estimated. You get no hidden numbers and no guessing games, just a fair look at both sides.
Key Takeaways
- Belkins runs a large, standardized operation with a proven track record, but it costs more and locks you in longer: Estimates put its full-service retainers between $5,000 and $14,800-plus a month, with a commonly cited contract minimum of 3 to 6 months.
- Outbound Sales Pro runs a leaner, US-based model on a six-month standard engagement with a built-in evidence point before renewal: Pricing starts between $6,499 -$11,999/mo for a six-month term, with at least two dedicated SDRs staffed on your account and a day-90 check-in against agreed KPI benchmarks.
- The biggest difference between the two agencies is how each one defines a “qualified meeting” in the contract: Belkins guarantees a meeting count that you help define, while Outbound Sales Pro reports weekly against its own held-and-qualified standard, tracked across reply quality, conversation-to-meeting rate, and held rate.

We’ll walk through it line by line and show you exactly where Outbound Sales Pro compares.
What Is Belkins and What Do They Do?
Belkins is a large-scale B2B appointment-setting and lead generation agency founded in 2017. It runs omnichannel outreach across email, LinkedIn, and cold and intent-based calling, backed by manual lead research, ICP and TAM mapping, and its own email deliverability infrastructure. The company has grown into a sizable operation, with 201 to 500 employees spread across offices on multiple continents.
Belkins tends to work best with mid-market to enterprise B2B companies that already have an established product, a longer sales cycle, and a higher average contract value. It holds hundreds of published client reviews across G2 and Clutch, which is part of why it shows up in nearly every Belkins review search you run. You can also read our own Belkins review for more background before the comparison starts.
What is Outbound Sales Pro and What Do They Do?
Outbound Sales Pro is a US-based outsourced SDR and appointment-setting partner. Instead of running a large, standardized bench like Belkins, we staff each account with a smaller, dedicated team of at least two SDRs built around your ideal customer profile and a held-meeting target. The retainer is scoped at the proposal stage instead of sold off a published volume tier, starting at $11,999 a month for a minimum six-month contract.
The model is built to hand qualified meetings straight to your closing team, stopping short of running the deal through to a signed contract. That makes it a fit for companies that already have account executives but lack a dedicated top-of-funnel function. It’s exactly what buyers mean when they search for “an outbound agency that hands off to my own reps”.
OSP reports weekly on reply quality, conversation-to-meeting rate, held rate, and cost per meeting. We hold a 5.0 out of 5 rating on G2.

Belkins does not publish a public rate card, so every dollar figure in its row is pulled from third-party reviews and comparison sites rather than from Belkins itself. Outbound Sales Pro’s starting figure is directional too, since your final retainer gets scoped once we know your ICP, channel mix, and meeting target. Treat both numbers as a starting point for your own conversation, since neither one is a locked-in quote yet.
This table gives you the headline differences, but the decision usually comes down to two things: what you will actually pay per qualified meeting, and what happens if you need to walk away.

Belkins and Outbound Sales Pro run a similar multi-channel mix on paper: email, LinkedIn, and calling. Belkins adds account-based marketing and CRM consulting as extra services, while OSP builds its own email deliverability infrastructure directly into the core program. The channels look alike from a distance, but the team behind them does not.
Belkins pairs a dedicated account manager and SDR pod with a much larger shared bench of 201 to 500 employees behind the scenes. Outbound Sales Pro runs a smaller, dedicated US-based team instead, so the same people who learn your product stay on your account. Neither structure is wrong, but they suit different buyers.
On contract length, multiple third-party reviews cite a 3 to 6 month minimum for Belkins, though Belkins itself does not publish this figure, and it can vary by tier. Outbound Sales Pro runs a six-month standard engagement with no annual lock-in, built around a day-90 check-in where you and your account team review results against KPI benchmarks agreed at kickoff. That checkpoint is the part most buyers do not think to ask about until they are already stuck in a contract.
Belkins’ guarantee structure ties to a meeting count, but you are the one who defines what counts as qualified inside that agreement. Outbound Sales Pro reports weekly against a held-and-qualified standard it defines and applies the same way every week. That weekly cadence is what turns “trust us” into something you can actually check.

Note: Belkins does not publish pricing. Every figure above is drawn from third-party reviews and comparison sites and should be checked against a current Belkins proposal before you budget around it.
Belkins does not publish its pricing, so every number in this table comes from third-party reviews and comparison sites, since Belkins itself has no public rate card to pull from. Its own pricing page lists four tiers, for small businesses, growth, growth plus, and enterprise, each tied to a yearly appointment volume instead of a dollar figure. That structure makes getting Belkins pricing without a sales call nearly impossible, since every tier needs a conversation with their sales team before a number shows up.
Outbound Sales Pro’s retainer generally starts at $11,999 a month, staffed with at least two dedicated SDRs on your account from day one. That figure is shaped by your ICP, channel mix, and held-meeting target, so it gets confirmed once we understand your goals rather than pulled from a fixed published tier. Either way, what you pay per qualified meeting matters more than the monthly sticker price alone.
Cost per held, qualified meeting is the number that actually decides value here. A lower retainer with a weak qualification standard can end up costing more per booked opportunity than a higher one with a strict definition of “qualified.” That is the core Belkins cost per meeting question, and it applies just as much when you run the same math on Outbound Sales Pro or any other agency.
This is also the section to bookmark if you are running a broader appointment setting agency pricing comparison, since it is built around the same principle: cost per meeting is what counts, more than cost per month. Whether you are pricing out Belkins, Outbound Sales Pro, or another option entirely, that one framework holds up in any cost to outsource SDR 2026 comparison you run. Our own Cost Per Meeting framework walks through the full math if you want to run your own numbers.

Belkins runs a broader initial buildout, including a sales audit and an addressable market calculation, before outreach goes live. Third-party reviews cite 4 to 6 weeks before a Belkins campaign reaches full implementation, with meaningful results typically showing up in the 60 to 90 day range. That is a thorough process, but it is also a longer runway before you see your first meeting.
Outbound Sales Pro runs a shorter, more concentrated alignment period instead. Your dedicated team gets briefed on your ICP, messaging, and qualification criteria, then starts booking meetings directly onto your closers’ calendars, with weekly reporting from day one. A longer buildout is not automatically a red flag, since it can reflect a more careful process, so weigh it against how fast you actually need pipeline.
Who Should Choose Belkins vs Who Should Choose Outbound Sales Pro
Belkins is a reasonable choice if you run an established, larger B2B company with a bigger budget and you want a large, standardized operation with a long track record. You should be comfortable committing to a multi-month term for a fully managed, multi-channel program if you go this route. That trade-off works well for buyers who value scale and a proven playbook over flexibility.
Outbound Sales Pro is one of the best Belkins alternatives for SMEs, built for growing B2B and SaaS teams that already have in-house account executives and just need a dedicated top-of-funnel function. If you have been searching for Belkins alternatives for growing sales teams, this handoff model, paired with a US-based team of at least two dedicated SDRs and weekly reporting, is usually why teams land here. You get a six-month minimum contract built around a day-90 review, plus clear visibility into held-meeting quality over raw activity counts.
The clearest distinction comes down to buying motion. A company assembling a full-cycle outsourced program at scale likely leans toward Belkins, while a company that already has closers and just needs its top-of-funnel handled is the clearer fit for Outbound Sales Pro. If you’re still asking which appointment setting agency has the best meeting quality, look at how each one defines “qualified” in its contract before you compare sticker prices.
Choose Belkins if:
- You run an established, larger B2B company with a bigger budget and want the largest standardized operation available.
- You’re comfortable committing to a fully managed, multi-channel program for a multi-month term. Belkins’ commonly cited 3 to 6 month terms fit that model.
- You want a large shared bench of SDRs behind your account, backed by a long track record and hundreds of published reviews.
- Your sales cycle is long and your average contract value is high enough to absorb a bigger monthly retainer.
Choose Outbound Sales Pro if:
- You already have in-house account executives and just need qualified meetings handed off to them.
- You want a dedicated, US-based team of at least two SDRs on your account instead of a rotating shared bench.
- You want a defined checkpoint built into your term. Outbound Sales Pro’s six-month minimum contract includes a day-90 review and agreed KPI benchmarks.
- You want weekly visibility into held, qualified meetings, tracked against reply quality, conversation-to-meeting rate, and cost per meeting.

FAQs About Belkins and Outbound Sales Pro
Belkins is a B2B lead generation and appointment-setting agency founded in 2017. It runs omnichannel outreach across email, LinkedIn, and cold and intent-based calling, plus manual lead research, ICP and TAM mapping, and its own email deliverability tooling. If you’ve read a Belkins review that only covers pricing, this is the fuller picture of what the service includes.
Belkins does not publish its pricing, but third-party estimates put entry-level engagements around $2,000 to $5,000 a month and full-service retainers between $5,000 and $14,800 or more a month. Figures vary by source, tier, and contract length, so treat any number you see, including these, as a starting point rather than a quote. Confirm the exact figure directly with Belkins before you budget around it.
Belkins holds roughly 4.7 out of 5 on G2, based on 93 reviews, and about 4.9 out of 5 on Clutch, based on 233 reviews. It also has reviews on Capterra and TrustRadius. Review counts and scores can shift over time, so it is worth checking the live pages before you cite them in your own vendor comparison.
Belkins does not publish a contract minimum, but multiple third-party reviews commonly cite a 3- to 6-month term, and the exact length can vary by tier. Its own pricing page lists volume-based tiers instead of contract lengths, so you will need to confirm the term directly during a sales call. Ask this question early, since it affects how much risk you are taking on before results show up.
Belkins’ agreements typically guarantee a meeting count, with the buyer defining the qualification criteria that count toward that number. This means the Belkins qualified meeting definition is something you negotiate into your own contract rather than something set for you. Get that definition in writing before you sign, since a vague standard is the most common source of dispute later.
Outbound Sales Pro is one of the best Belkins alternatives for SMEs, built for growing B2B and SaaS teams, with a retainer starting at $6,499 – $11,999 a month for a six-month contract, at least two dedicated SDRs staffed on your account, and weekly reporting on held, qualified meetings. It is one of the more direct comparisons if you want a defined checkpoint built into your term rather than a guaranteed count alone. Book a demo to compare it against your own Belkins proposal side by side.
Belkins can be worth it if you have an established product, a bigger budget, and you want a large, standardized operation with a long track record. It tends to be a heavier commitment for a smaller, faster-growing team that needs more flexibility. Whether Belkins is worth it for you personally comes down to how much you value scale versus a shorter, checkpoint-based engagement.
Third-party reviews cite 4 to 6 weeks for a Belkins campaign to reach full implementation, with meaningful results typically emerging in the 60 to 90 day range. Outbound Sales Pro runs a shorter alignment period before meetings start landing on your closers’ calendars, with weekly reporting from day one. Either way, plan your internal resourcing in terms of weeks rather than days.
Outbound Sales Pro’s retainer starts at $6,499 – $11,999 a month for a six-month contract, staffed with at least two dedicated SDRs on your account. Pricing is shaped by your ICP, channel mix, and held-meeting target, and the term is built around a day-90 check-in with KPI benchmarks agreed at kickoff. Reporting happens weekly, covering reply quality, conversation-to-meeting rate, held rate, and cost per meeting.
In a Belkins vs Outbound Sales Pro comparison for teams with their own closers, Outbound Sales Pro is built specifically to hand qualified meetings off to a client’s existing sales team, which makes it a closer fit if you already have account executives in place. Belkins can run a similar handoff, but it is more often sized for larger, full-cycle programs. If your top-of-funnel function is the piece you are missing, that difference is usually the deciding factor.
