Are you great at the expertise it takes to run your business but find it difficult to handle finances and other backend functions?

Corner Office is a full service company that provides implementation, training and consulting services on diverse accounting platforms for business owners and bookkeepers.

I knew I needed someone who understood the back end of running a business.

Some of the most crucial parts of a businesses is having correct bookkeeping, which leads to great optics into what is really going on in a business. Without these optics, a company runs blind, which is a big reason so many startups fail within the first two years. Diana and the Corner Office team did an amazing job from day one in ensuring the bookkeeping was properly kept up in QuickBooks, and thanks to that, we knew exactly when we could invest more into the business, and when we needed to slow down on spending. I’d highly recommend Diana and team for anyone who currently does not have full optics into their true finances!

I own a small service business that had been utilizing very basic QuickBooks.

My previous QB’s processor (Ex-Wife) up and quit and Diana, came to my rescue!! She knows her stuff, and is quick and competent, and explains things in a very user-friendly way. She had the patience to deal with my lack of QB knowledge and also assisted in accessing my expense and income accounts. Diana is quite fast at analyzing and proficient with customizing my QB’s. I would recommend her to all who need assistance with their accounting system!

I hired Diana four years ago to consult on problems related to MACH Energy’s use of QuickBooks Enterprise and to provide part-time bookkeeping services.

She has proved to be invaluable in this role. She manages the invoicing, sales tax calculation, A/R and A/P processes, involving over 1,500 invoices per year and payment of all the Company’s consultants and vendors. She does bank account reconciliations and other tasks needed for timely closing of the company’s books. And, when there is a QuickBooks question or issue, she’s on-call to answer or resolve it. I enjoy working with Diana and highly recommend her.

Working with Diana is a gas. But more importantly, she really makes things happen.

If Intuit only offered a PhD on the Quickbooks platform she would have one. I mean she knows this stuff inside and out. What she doesn’t know she comes to understand in the time it takes you to pose another question. Our business has been streamlined in a very compelling way in just a couple weeks of working with Diana. By utilizing reports she’s helped us create, I can rapidly understand the performance of our business on levels I hadn’t imagined. I actually know how much money we’re earning now. Imagine that.

Corner Office has been an essential part of our business.

When we started working with them, they were immediately able to make sense of all our various accounts, income streams and expenses, which was fairly complicated. Then they set up an organized, sustainable and manageable record keeping process for moving forward. It is such a relief! Also they are always accessible, responsive and on top of it. And best of all, Diana is a riot and a joy to work with!

Diana’s Corner Office is part of my team.

Her unequaled expertise with QuickBooks and vast bookkeeping knowledge has given me precious extra time to devote to the family business and my favorite hobby, golf. I thank her for making this aspect of my business extremely easy. I highly recommend her services to all small and medium size businesses.
