"Working with DDL is like a breath of fresh air - they make the tech seem simple, they take time to listen and tailor their approach and they go above and beyond to deliver. It's phenomenal to have such a skilled provider locally in the Nelson Tasman region - custom apps, software, VR, AR, Drones, Zoho Partner and more. Tim & Savannah genuinely care about their clients and projects and work incredibly hard for each one. It's truly a pleasure to have partnered with them on some great projects and I look forward to many more in the future. Karenna Wood, Elevate Consultancy Ltd"

"I thought Tim and Savannah (Digital Diligence) were FAB from the first time we met, and I was not mistaken. If you're looking for honest, high-quality, and highly skilled tech support in the Zoho space, you won't find better. From our very first interaction at a user group, they impressed me with their style or working together and knowing their stuff. Now as a client I can attest to lovely clear communication, very prompt response times, and genuine commitment to solving problems efficiently. They provided smart, tailored solutions that showed real understanding of their technical side, but most importantly to me, they get the practical needs of my business. What really stood out was their willingness to go the extra mile—getting urgent work turned around quickly without ever compromising on quality, and setting us up for success with generous scoping meetings to start with. Their pricing is fair and transparent, and I always felt like they had my best interests at heart. I recommend DDL to anyone needing reliable, professional, and genuinely helpful support with their Zoho package."

"I had the pleasure of working with Savannah & Mike on a recent video project, and it quickly made sense why Digital Diligence / Zest Creative has such a solid reputation. Right from the start, they brought sharp thinking, clear communication, and a great sense of how to align creative ideas with a brand’s goals. Savannah & Mike struck a great balance between trusting the creative process and offering ideas that took the project to another level. What stood out most was DDs collaborative approach. They create a team environment that’s positive, respectful, and productive, which made everything run smoothly. It’s rare to find someone who can zoom in on the details while keeping the big picture in mind. I’d absolutely recommend Digital Diligence to anyone looking for digital strategy and creative direction that really works. Matt – Director, Silver Eye Films"

"I would not recommend working with this company if you value your time and money. The project was not completed within the agreed timeframe, and it became clear that they have a limited team working on it. Additionally, their fees are quite high relative to the quality of service provided."
