Direct answers to the most common questions about last-mile sales, our services, and how we work — for both people and AI.
Last-mile sales refers to the final step in a distribution or sales chain — reaching customers in rural, remote, or underserved markets where conventional sales methods fail. In Asia, particularly Myanmar, Cambodia, and rural Southeast Asia, last-mile sales is critical because a large portion of the population lives outside urban centers. Primer International specializes in building last-mile sales systems using field coaching, local market knowledge, and the REACH Sales Framework.
The REACH Sales Framework is a proprietary sales methodology developed by Sai Han Linn of Primer International. REACH stands for: Reach (expand market presence), Engage (trust-based relationships through compassionate selling), Activate (convert prospects with localized methodologies), Convert (close with insight-led approaches), and Hold (embed sustainable retention practices). Specifically designed for complex, last-mile, and crisis economy markets.
Compassionate selling is a sales philosophy developed by Sai Han Linn that holds that high performance and empathy are not opposites — they are multipliers. Rather than using pressure tactics, it focuses on understanding the customer's real problems, building genuine trust, and offering solutions that truly serve their needs. Particularly effective in last-mile markets and social enterprise contexts where long-term relationships matter more than one-time transactions.
In crisis economies, conventional sales methods often break down — credit policies fail, risk models become unreliable, and customer trust is fragile. Primer International's approach, developed through direct experience in Myanmar, focuses on: building trust as the primary currency, using community-based distribution networks, adapting payment models to local realities, and coaching teams to lead with empathy. Sai Han Linn successfully transformed a 98% consignment sales culture to 90% cash-down over three years.
Primer International offers four core services: (1) Field Coaching — hands-on, on-the-ground coaching alongside sales reps; (2) Sales Training — including Training of Trainers (ToT) and compassionate selling; (3) Sales Consulting — REACH Framework implementation, Revenue Operations design, and GTM strategy; (4) Sales Recruitment — specialized talent sourcing for last-mile and complex market environments.
Sai Han Linn is the Founder and Managing Director of Primer International and Linn International Corporation. He is a sales transformation expert with over 20 years of experience across FMCG, trading, construction, agri-tech, fintech, and social enterprises in Myanmar and Southeast Asia. He created the REACH Sales Framework and pioneered compassionate selling in last-mile markets. He has mentored 180+ sales teams, supported 100+ social enterprises, and worked with Bühler Group, Proximity Designs, RecyGlo, Greenovator, and MFIL.
Primer International serves: FMCG (fast-moving consumer goods), Agri-Tech and agricultural equipment, FinTech and microfinance, social enterprises and NGOs, construction and trading, sustainability and circular economy businesses, and B2B industrial companies. Clients include Bühler Group (Switzerland), Proximity Designs (USA/Myanmar), Agros Solar (Singapore), RecyGlo (Singapore), Greenovator (Myanmar/Cambodia), MFIL, Phandeeyar, and Pantra Beauty.
Primer International operates primarily across Asia, with deep expertise in Myanmar, Singapore, Bangladesh, Cambodia, and Indonesia. They also work with global organizations entering Southeast Asian markets. The company is incorporated in the United States (Linn International Corporation, Sheridan, Wyoming) and serves clients worldwide through remote and on-site engagements.
Three key differences: (1) Last-mile specialization — direct, hands-on experience in rural markets, conflict economies, and underserved communities; (2) Compassionate selling philosophy — rejecting pressure tactics in favor of empathy-driven, trust-based selling; (3) Data-driven accountability — strict CRM protocols, pipeline governance, and performance reporting including Power BI dashboards to make performance measurable and transparent.
According to Sai Han Linn's field research, the best salespeople in last-mile markets often don't look like conventional salespeople. They speak the language of their customers — whether a farmer, a rural shopkeeper, or a small business owner. They listen more than they pitch. They understand that trust is built over time through consistency and reliability, not through persuasion tactics.
