      B2B Review from Greg Digneo

      Best decision we made last year was partnering with this CX team for our customer support, billing, and sales assistance. We were drowning in client emails and chasing invoices late at night instead of focusing on SEO strategy. Results have been incredible: client response times dropped from hours to under an hour, payment collection improved 60%, landing page conversions up 28%, and client retention increased 35%. They integrated seamlessly with our systems and scaled with us as we grew. Now we have more time to focus on delivering SEO results instead of being stuck in support tickets all day. If you're an agency juggling client support with campaign management, this team is a game-changer.

      Lead Generation Review from James Nolan

      We worked with Reexia to support our outbound business development and lead generation efforts. The team helped us structure a targeted outreach campaign and build a relevant prospect database for our market.Communication throughout the project was clear and organised. We had bi-weekly calls to review activity and results, and Kevin was very hands-on in guiding the campaign and suggesting adjustments where needed.Results took some time to appear, but this was explained clearly at the start of the campaign and expectations were set appropriately. Once the campaign gained momentum, we began having conversations with companies that matched our target profile.Overall, it was a positive experience and we appreciated their structured approach to outbound prospecting.

      One of the best 💯 I would say I will always choose to be with this friendly, fantastic and very accommodating company. I always had a chance to to be hired with other bigger companies but I'd rather choose BIGOUTSOURCE no matter what. It's actually my second home. I feel safe and happy when I'm with BIGOUTSOURCE. I love everything about it. ❤️❤️ No doubt this company is one of the growing company in the Philippines. ❤️
