Between a rent-to-own portfolio of 20+ active deals, an automated trading operation, and general real estate investing, my books are never simple. Diana and the team at DLI keep it all straight. She's systems-driven and detail-oriented, the kind of bookkeeper who builds a process for everything instead of just reacting. She's proactive too, she catches things before they're an issue instead of waiting for you to ask. That matters when you're juggling multiple entities and need someone you can trust to flag things before they become problems. If you're looking for a bookkeeper who treats your business like it's hers, work with Diana.
If we could give 100 stars to Diana and her DLI Team we would! Diana was recommended to us at a very difficult time in our business, we were completely lost as to where to start and what to do next with our situation. Diana and her team completely took the wheel and got us in to an amazing place. They work very hard to make sure you and your business are running at full speed and you are completely set up for success. Diana is very straight forward and to the point, there is never any question or confusion as to what she needs from you every step of the way which is fantastic. She will always take the time to explain everything to you so you understand what is happening, why it is happening and what you need to do moving forward. Her and her team of hard workers are always there to hold you accountable for your business and keep you on track. I honestly do not know what would have done or where we would be without Diana and DLI Business Services. I would recommend them to anyone no question!
