David has been nothing short of amazing to work with. He helped us integrate our reservations system with QuickBooks Online, an area I am not knowledgeable in, and his expertise made the process smooth. He has been extremely knowledgeable, patient, and helpful, always troubleshooting any roadblocks we’ve encountered along the way. David is professional, reliable, and consistently delivers great work. I would highly recommend him to anyone looking for support in this area.

Working with David and Mercology was a great decision! Not only did he save me time and frustration, he was a pleasure to work with. He made sure to fully understand what it was I was looking for, even bringing things up I didn't think of. He also took the time to explain everything to me and made sure everything was functioning the way that it should. I would definitely recommend David and Mercology, and will be using them exclusively for all of my zapier automations in the future.

David is a valuable asset to any business needing expertise in automating work flow processes. Aside from his technical expertise, he has a very strong work ethic and actually becomes a member of your team. He is quick to understand business goals, current architecture and configuring quick solutions. I highly recommend his services!

If you need help with anything related to Zapier, big or small, go directly to David for expert tech and super nice service.

I love working with David Mercer - he is so easy to talk to. I explain what I need and he takes care of the rest! He is very attentive whenever I've requested something and I have never had any issues with his work. Looking forward to working together again in the future!

David was helpful and made it right to the point.
