Mary and her staff have been wonderful. My husband and I own a franchise, and we have a very busy life, but Mary and her team have done a phenomenal job of keeping us happy and organized. Life can get very hectic, but she is always helping us save and her Profit & Loss statements are like liquid gold. Thanks Mary! We absolutely would be scrambling without Mary and staff. It took us a good 6 months to get the flow of things from our end, but once we did, this turned into the perfect business marriage (if you will). Mary and team have done an excellent job staying on top of us. Thank you so much for helping us with our franchise. Thank you, thank you! I HIGHLY recommend! read more

I never even had an opportunity to use Mary's bookkeeping, so I can't speak to her services. My experience was in setting up my practice to work with Mary. My first clue was when she quoted me an hourly rate of $75/hour, but then wanted to charge me $350/month without ever having SEEN my books or my needs. She said she's been doing this a "long time" and could "tell" it would be 5-7 hours per month of work. That being said, what if it was 5? Or less than 5? Would I get a refund? No response. But I'm in need, so I still said ok. After dozens of emails back and forth, I provided her with passwords for my business accounts, credit cards, and Quick books portable file. I set her up with everything she needed to start my work. The second clue she gave me was asking me (again) which accounts were which (letting me know she couldn't handle complex law firm accounts). She also asked me repeatedly for things I had previously sent her in the same email string. When I responded to her that everything had been provided she emailed me back immediately and stated, "We have decided we are too busy to handle your books." Period. Mind you, by this time, I have told my current bookkeeper that I'm going with someone new. Oy-Vey! After receiving ALL my client's private information in my QB file, my usernames, passwords, statements, etc. and me firing my other bookkeeper, I'll have to change everything now and there's nothing I can do to retrieve my QB portable file. To say I was disappointed is a complete understatement. She's definitely not as organized as she claims to be. I definitely don't see how she has this many 5 star ratings. ??? UPDATE: just read her reply comment on my post. Takes no responsibility for her role in what happened. Just puts it back on me. Whatever Mary. You can't even be honest that you said you were "too busy". *eye roll*. Clearly I dodged a bullet reading your other 1 star reviews. read more

Great bookkeeping service and always responsive. Goes above and beyond as a vendor. Been using her and her team for years.

I have worked with Mary at Mary's bookkeeping for several years now. Mary and her team are very efficient, thorough, and are priced very fairly. I highly recommend Mary's bookkeeping to any business, large or small, or anywhere in between. read more

Always an enjoyable and professional experience working with Mary, Jeff, and the entire team. We've been using them for bookkeeping services for several years now and they honestly feel like part of our own in-house bookkeeping team with the level of trust, respect, and goodwill they continue to share with us. As we've grown they have adapted and catered to our changing needs seamlessly. Phone conversations and in person meetings are always super helpful and friendly. Highly recommend! read more

I have a small boutique college counseling service in Tustin and have been working with Mary's Bookkeeping for about 14 years (possibly longer). Whenever I've dropped the ball by getting in 1099 information late, or W9s, or..., they get me moving in the right direction and I can devote my time to business not bookkeeping. If I need an answer on QuickBooks, they return my call right away and tolerate my ignorance: that's invaluable. read more

We are a Medical Office in Beverly Hills, and we have been working with Mary and her staff for a few years now. There's not one negative comment we can say. They are always available, on top of things, and reliable. Communication is easy and clear at all times! read more

In our latest correspondence, Mary accused me of "slander," however it cannot be slander when what I have said is true and can be backed up with evidence. Then she proceeded to threaten to have her friends leave bad fake reviews for my business here on Yelp. Ironically, that would be actual slander (or libel since it would be written), and there are legal ramifications for that. Actually emailing me and having it in writing that she intends on having "friends" leave fake reviews for my business is a SERIOUS claim. I don't owe this person anything. She has shown malicious intent toward me and my business, and I am not taking this lightly. All reviews for my business on Yelp or elsewhere will be closely monitored. It is very easy to trace reviews to determine their validity, and appropriate action will be taken if false claims are discovered. read more

My husband and I own a couple Nekter Juice Bars and wanted someone to take over our books completely. We were with a large firm before hand who let things slip through the cracks and I am a very detailed person. With my business background, I considered doing them myself, yet we wanted to spend our time focusing on sales and marketing. We looked at 3 people before going with her and are very happy that we made the right decision. Mary has been doing our books for 6 months now and she is amazing. Everything from paying our bills to doing our P/L's for we have her do everything for us. I didn't think I could meet someone MORE detailed than me, but I did. She is a big part of our business for having her allows us to focus on other areas of the business. Mary and her husband Jeff (an accountant) knows their stuff. read more

Mary's Bookkeeping has been a huge help to me. I started an online business and wasn't sure where to begin. I hired them back in January of this year. They have been so patient in teaching me and helping me get all my bookkeeping in order and understand the financials. They pay my bills on time and saved me a lot of headaches. I have read some of the reviews on here but I have had nothing but a pleasant interaction with her and the staff. I am also a very easy flexible person to work with so I am sure that helps. read more

I run a small construction and real estate company. We needed help cleaning up the books and getting them up to date weekly so we could know were our project budgets were at more often. I called Mary's based on her good reviews on Yelp and am happy to say I have not been disappointed. Her staff is skilled, professional, and diligent at their job. I'm now able to click into quickbooks myself anytime and see a much more accurate picture of my jobs, which is what I was looking for. Thanks! read more

I have my own Skin Care Business in Irvine and I have been "trying" to do my own bookkeeping for years. My business has grown a lot this year that I do not have the time to do my own bookkeeping. I am so glad Mary is now doing all my bookkeeping, now I don't have to worry about doing anything wrong!!! I am very pleased with how professional she and her assistant Erika are when returning phone calls and emails. Mary, also does my merchant account and has saved me a lot of money on credit card transaction fees. I highly recommend Mary's Bookkeeping.....Thank you Mary and Erika!!!! read more

We found Mary on Yelp and we are SO glad that we did! We cannot say enough how easy to work with she and her husband Jeff were throughout the entire experience. The project that I came to them with was not a typical book keeping project and I had actually been turned down by at least 8-10 other accounting firms that were very rigid in what they were willing to take on. I must say, it turned out to be a blessing in disguise because from the initial meeting with Mary through the completion she made the experience a piece of cake. I cannot thank them enough and we are absolutely going to be using their services going forward! read more

I love working with Mary.... Always efficient & friendly knowledgeable staff. I've worked with Mary for the past 4 years & I will continue to bring my business here! :) read more

I had the opportunity to be introduced to Mary a couple years back, and ever since all of my bookkeeping needs have been met. She is beyond professional and very organized. I love that she has her office in her home. It gives our meetings a more relaxed feel. I have recommended Mary's Bookkeeping to many people and I will continue to do so. I have no regrets with putting my business in her hands. Thanks Mary! read more

I've had the pleasure of working with Mary and her staff for over two years now. She is the bookkeeper of my employer, and has been for four+ years. I'm not a business owner, but as an employee, I couldn't ask for a better bookkeeper. Mary and Erika are always helpful and knowledgeable, by phone or by email, and never hesitate to answer any questions-regardless if they have answered them a time or two in the past. They are easily accessible, and have speedy turnaround times. Payroll is a breeze with Mary's Bookkeeping, and I've never had an issue. It is incredibly convenient to not deal with payroll in-office. One of the best things about working with Mary is that she really cares. When she asks how you are doing, she means it. She cares about her community, she cares about the environment, she cares about animal welfare, and she cares about equality. Coupled with someone that not only knows how to do their job, but does it tremendously well, and you have a recipe for happy clients! read more

I manage a small video store in southern Orange County. Mary has been great helping us stay afloat during hard times.

As an independent contractor with multiple accounts I needed someone to completely take over my personal bookkeeping. After interviewing several companies and meeting with Mary in person, her agency was my choice. She always responds right away to e-mails or calls, sends me monthly, detailed financial statements, and her rates are fair. It is well worth it to me to have a professional like Mary keep my books so I can focus my time and energy on other things. read more

I have a small part-time home-based business and bookkeeping is something that I just don't have much time to dedicate to nor is it something I enjoy doing. I've been working with Mary's Bookkeeping for a few months now and I'm very pleased with her service. She is very organized and makes it easy for me to "step back" and focus on the aspects of my business. Because I'm such a small business, she was very flexible about her rates and really assessed my needs (quarterly bookkeeping instead of monthly) to help save me some money and is overall just a pleasure to work with! read more

I have had many bookkeepers come and go. They screwed up my books, or could not provide me with the level of financial detail reports that I required as a President and Managing Partner of a successful mid-size law firm. Mary's Bookkeeping has been a Godsend. They came in, cleaned up the mess left by my prior bookkeeper, got all of books in order, assumed responsibility for my payroll and provided me the level of detail I needed to manage my firm and make a profit! They provide excellent bookkeeping services. read more

I run a promotional advertising business. I am constantly busy so I have very little time to do my books. But every since I'd hired Mary's Bookkeeping it really takes a load off my back. They are professional... they do their job without with me having to remind them. It's like have your own accounting department but without the full time staff. Very professional! read more

Mary and her staff are extremely detailed and dedicated to helping your business. I have often felt as though she treats my bookkeeping as if it were for her own business. To me, that says everything. I was nervous to hand over my bookkeeping to anyone, but she has definetly exceeded my expectations. Highly recommend!!! read more
