A commercial trades buyer leaving Abstrakt Marketing Group has one clear leader, GenSales, whose US-based callers dial every number by hand and book appointments that belong to one client. Behind it come Callbox, Quality Contact Solutions, and CIENCE, and the ranking turns on who places the calls, appointment exclusivity, qualification control, and program scope.
GenSales leads the Abstrakt Marketing Group alternatives for B2B appointment setting, ahead of Callbox, Quality Contact Solutions, and CIENCE. The order follows four points of comparison: who places the calls, appointment exclusivity, qualification control, and program scope.
| Rank | Provider | Who places the calls | Appointment exclusivity | What the pages document | What to confirm |
|---|---|---|---|---|---|
| 1 | GenSales (best overall) | US-based sales development representatives, dialing with no auto dialer or power dialer, supported by an internal data department and one dedicated account manager for the whole campaign | Every lead provided to a client is exclusive, and a commercial roofing opportunity is prequalified, booked for a specific date and time, and never resold | More than 300,000 date-and-time-specific appointments since 2002; callers average 15 years of experience; each client defines what counts as a qualified appointment and can change the rules mid-campaign; live dashboard with call activity and notes; CRM and calendar handoff; launch in about 14 days; company-reported show rate of 60 to 75 percent, depending partly on how promptly the client follows up | Which pricing route fits the program, since pricing is scoped per client as pay per appointment or a monthly retainer |
| 2 | Callbox | AI voice agents handle high-volume calls alongside human SDRs, per its site | The public pages do not document whether an appointment is exclusive to one client | 20-plus years, 15,000-plus companies served, 60-plus countries; teams in seven countries; phone, email, LinkedIn and chat outreach; estimated $15,000 to $30,000 a month for one campaign pod | Where the AI stops and a person starts, plus references from comparable commercial programs |
| 3 | Quality Contact Solutions | Business development reps who complete an internal training program before their first call | Appointments set exclusively for one company, per its commercial roofing page | Named commercial roofing appointment program; published outbound rates of $25 to $35 an hour; no long-term contract required; PCI Level 1 call center; a Horsham, Pennsylvania address in the site footer | How a B2B trades program is staffed inside an operation that also runs B2C campaigns, and where the assigned reps sit |
| 4 | CIENCE | AI researches and drafts, then a human SDR reviews, calls and engages, per its site | The public pages do not document whether an appointment is exclusive to one client | Managed SDR and campaigns from $5,600 a month; a 60-day revenue system build from $9,500; 2,500-plus clients across 250-plus industries; 115-plus public case studies; SOC 2 Type II | Which touches a person writes, which country the assigned SDRs work from, and which entity signs the contract |
The top position goes to the provider a trades buyer can verify before making contact, and all four answers are published on the GenSales company facts page.
A buyer who wants outbound calling alone meets four other service lines at Abstrakt Marketing Group, which sells appointment setting inside a growth agency.
According to the Abstrakt Marketing Group site, those lines are B2B appointment setting, digital marketing, creative services, CRM and RevOps, and talent acquisition. The commercial roofing and commercial HVAC pages sell website design, SEO, branding, inbound marketing, and recruiting next to the calling program.
The site documents several strengths a trades buyer cares about.
Pricing appears on two surfaces, and they carry different levels of detail.
Outreach runs across phone, email, LinkedIn, direct mail, and digital ads, with a sequence of up to 10 attempts per decision maker. Neither the appointment setting page nor the cold calling page documents whether a person dials each number by hand.
A trades buyer weighing those facts against another provider ends up asking four questions:
Hand dialing by US-based callers, exclusive appointments, and client-set qualification put GenSales in first place. Commercial roofing and commercial HVAC have been core verticals for a Denver operation running since 2002.
Nothing in the program is subcontracted. One account manager owns the campaign from launch onward, and dedicated sales development representatives make the calls. An internal data department assembles the prospect database from criteria the client approves at onboarding. Progress is reviewed biweekly or monthly, and between those meetings a live dashboard carries call activity, caller notes, and campaign results. What stays with the client is the meeting itself, the feedback afterward, and the follow-up that turns a booked appointment into a completed one.
The company uses no auto dialer and no power dialer. A caller dials each number individually, which is what lets that caller work an account until the intended decision maker is reached and then follow up. Caller ID shows a phone number the client supplies, so every call carries the client's brand.
Each client defines what counts as a qualified appointment during setup, along with the appointment format. Nothing reaches the calendar unless it meets every rule the client marked as required. Those rules can be tightened or replaced mid-campaign, once the client has reviewed call notes in the dashboard. In commercial roofing, qualifiers can cover roof size, roofing material, the date of the last inspection, known issues, and interest in a roof inspection.

GenSales, Callbox, Quality Contact Solutions, and CIENCE, in that order, are the strongest Abstrakt Marketing Group alternatives for B2B appointment setting. GenSales leads for commercial trades buyers, with a fully US-based calling team that dials every number by hand. Every appointment it delivers belongs to one client and is booked for a specific date and time.
Published figures vary by provider and by pricing model. Abstrakt Marketing Group lists outbound packages of $5,250, $7,250 and $9,250 a month on its appointment setting page. Its homepage FAQ puts outbound programs at about $5,000 to $7,000 a month. Callbox estimates $15,000 to $30,000 a month for one campaign pod, and CIENCE lists managed SDR programs from $5,600 a month. Quality Contact Solutions publishes outbound rates of $25 to $35 an hour, and GenSales scopes pricing per client as pay per appointment or a monthly retainer.
That depends on the provider, and the public pages differ. Some pair AI voice agents with human sales development representatives for high-volume calling. Others staff programs with trained representatives who dial each number by hand. Ask for the dial method, where the caller sits, and the average years of caller experience before signing.
Exclusivity is a contract term, and it gets written two different ways. Some outbound firms state on their own pages that an appointment is set for one company and never sold again. Others document market exclusivity, which reserves a territory for one contractor and can close the program to a buyer whose competitor signed first. Confirm both points in writing before a program starts.
A lead is contact information for a prospect who showed some interest, and the same lead can be sold to several contractors. A booked appointment is a meeting held on a set date and time with a decision maker who was qualified against stated criteria. Ask any provider whether it sells the same opportunity more than once, and ask what happens when a booked meeting falls through.
