I contacted David with a project that I had already built and was having trouble with the web loops. David jumped in, made some changes and said it was good. The same day, I noticed it wasn't working and emailed David. He suggested we get back together. When I asked if it would be an additional charge since I had already been billed, he said yes, because it is for his time and expertise. Well, I question the expertise as I never had anything work from him, it didn't matter. Do NOT recommend.

David was engaged to help us with integrating Vista Suite (Aviation Workflow Software) and Quickbooks to replace an old integated software package. David helped us every step of the way and managed with process with Zapier as well as the other two software vendors. David was professional and knowledgeable. I recommend his services and capabilities highly.

David and his team provide an outstanding service. I have availed of their services multiple times now and willl be using again no doubt. Exceptional and trustworthy help and advice. If you need any help at all with Zapier then David is the man. Thaniks David and team. Outstanding as always.

Daviid is knowledgeable, helpful, and quick. I highly recommend him.

I had two companies trying to help me set up my Zap to no avail, but I contacted David, he hopped on the phone with me for 30 minutes and fixed the issue (which actually turned out to be more than we thought!). A pleasure to work with!

I cannot recommend David Mercer, owner of MercOlogy, enough! He made the intimidating process of integrating our lists and platforms feel simple and straightforward. David took the time to really understand our needs and challenges and worked closely with me to create workflows that solved these issues. If you’re like me and don’t know where to start, meeting with David will instantly put you at ease and give you hope for fully integrated lists. Truly a game-changer!
