This guide examines five real Singapore-based telemarketing agencies that run B2B appointment-setting and lead-qualification campaigns, covering their dialing infrastructure, CRM integrations, and how they measure SQLs — not vanity call volumes.
Singapore B2B buyers pick up the phone less than they did five years ago, but outbound telemarketing still books more qualified meetings than cold email when the list, script, and dialer are engineered correctly. The five agencies below operate from Singapore, work within PDPA boundaries, and plug into common CRMs like HubSpot and Salesforce. They differ in scale, pricing model, and whether they also send a person on-site.
1. SalesWorks
SalesWorks has run outbound sales and telemarketing from Singapore since 2001, with regional teams across Southeast Asia. It does not just sit at a desk — its telemarketers book meetings that its field force takes over in person. That hybrid model works for logistics companies, industrial equipment distributors, and B2B SaaS firms that sell to procurement teams who still want a face-to-face demo.
Their Singapore desk uses predictive dialers with local phone numbers, and each campaign runs with strict do-not-call (DNC) checks. Reporting is not clickbait — you get daily CSAT on calls, connect rates, and meeting confirmation counts. SalesWorks also hardcodes A/B-tested scripts per vertical, and they will train agents on your product for two weeks before the first call goes out.
2. Telemarketing Asia
Telemarketing Asia is a local Singapore call centre that positions itself as a no-nonsense telemarketing provider for B2B appointment setting. It avoids running huge offshore fleets, so your calls stay inside Singapore’s jurisdiction. Agents are bilingual in English and Mandarin, which matters when calling Singapore’s SME owners or regional HQ procurement offices.
They run list cleaning before the campaign starts, removing numbers registered with the PDPA DNC registry. You get end-of-day call recordings and a live dashboard showing talk time, rejection reasons, and scheduled meeting counts. Their hourly rate includes a one-week trial period, which is useful if you want to validate messaging before committing to a full retainer. This agency is a good fit for companies that need a small, compliant Singapore desk rather than a pan-Asian blitz.
3. Exceed Asia
Exceed Asia covers both telemarketing and field sales, but their lead generation practice stands apart because they push for revenue-based accountability. They will agree on a cost per sales-qualified lead (SQL), not just cost per call. Their agents use Salesforce or Pipedrive to log every interaction, and your team sees the staged pipeline in near real-time.
For B2B tech firms selling into Singapore’s finance and logistics sectors, Exceed Asia builds territory maps so telemarketers only target accounts that match your ICP. Their script library includes objection-handling flows for common procurement questions around pricing and implementation timelines. They also minimise wasted demo slots — a meeting is only counted as an SQL if the decision-maker confirms attendance within 24 hours.
4. Callbox
Callbox operates a Singapore-facing B2B lead generation desk backed by their proprietary MarketIntel database. While the company started in the US, their Southeast Asia operation runs campaigns for Singapore-based firms targeting both local and regional buyers. Their model is multi-channel: telemarketing, email sequences, and LinkedIn touches woven into one outreach flow.
The telemarketing component is supported by an internal CRM that scores leads based on verbal interest, budget, and buying timeline. Callbox prices per appointment or qualified lead, and their team will integrate with your existing Salesforce or HubSpot setup via API. They are strongest for B2B SaaS and professional services firms that want a bigger outreach volume than a tiny local call centre can handle.
5. TDCX
TDCX is the heavyweight on this list. While they are known as a CX outsourcer, their B2B telesales and lead qualification unit operates from Singapore with AI-assisted dialers and multilingual teams supporting over 10 languages. If you need a few thousand calls per week without building an in-house team, TDCX gives you enterprise-grade telephony, compliance layers, and workforce management.
Their B2B unit sets appointments for technology clients, financial institutions, and e-commerce platforms. They track conversion at every stage — from the first call to meeting sign-off — and their reporting integrates with Power BI dashboards. Because TDCX handles volume, they are not the right pick for ultra-niche campaigns needing three calls a day. They are the answer for scale.
Agency Comparison Table
| Agency | Key Feature | Best For |
|---|---|---|
| SalesWorks | Hybrid telemarketing + field sales force | B2B deals that need in-person follow-through after a booked meeting |
| Telemarketing Asia | Singapore-only call desk, PDPA-compliant with local bilingual agents | Tightly controlled campaigns targeting Singapore SMEs and HQ procurement |
| Exceed Asia | Revenue-based pricing with Salesforce/Pipedrive pipeline tracking | Companies that want cost per SQL, not cost per call |
| Callbox | Multi-channel outreach with MarketIntel database and API integrations | B2B SaaS firms scaling lead volume across regional accounts |

Each agency works differently, so match the contract structure to your risk tolerance. Telemarketing Asia and Exceed Asia are better for small, compliant, and metric-clean campaigns. SalesWorks bridges phone outreach with field sales. Callbox and TDCX give you volume when you need the pipeline filled fast.
