We help small businesses turn their QuickBooks accounting from a burden to an advantage.


We are the experts that take bookkeeping off your plate and off your mind, freeing business owners from the worry, and allowing them to shift their focus and energies on their business.

The data from accurate financials brings advantages in making wise decisions in navigating your business.

Accounting is about compliance and has a historical bent to it. Yet you wouldn’t drive down the road at 75 mph looking backward. We offer Advisory Services to look ahead. Using accurate financial data to plan and achieve growth and success.

Excellence is a core value for us. This excellence in our client service and support is reflected in our client reviews, referrals, and was recognized when we were awarded the ‘2019 Winner of the San Diego Award Program – Bookkeeping Services’.

It is an honor to be entrusted with our client’s financials.

Bookkeeping you can rely upon

Whether or not you use Quickbooks, you need to have a system for categorizing expenses — not only so you can see what’s actually happening — but so you can capture all of the savings now available to business owners (if only they knew about them).

The right advice, at the right time

It doesn’t help to have your accountant tell you that you are running in the red — after you’ve buried yourself in debt. Or that a particular product/service category is booming — after you’ve finished your sales cycle. Let us point you where you need to go.

We have struggled for years needing help here and there from someone. We got so lucky finding Luis! He is so knowledgable and so helpful. He is the easiest person to work with and he does it with a smile on his face. He responds quickly and helps us work through any issues we are experiencing.


Luis is incredibly hardworking and intelligent with the work he does! I found him from the Quickbooks ProAdvisor and feel very fortunate. He's helped on the bookkeeping for both with our cannabis business and our other business. Not having a lot of time is a common issue for most business owners and Luis helped ease the stress of that by taking on the tedious yet important tasks that I didn't have time for. His expertise, demeanor and willingness to help in any way are the reason we're keeping him! Find a bookkeeper than you can trust like Luis.


I am very new to getting organized on Quickbooks online, and Luis's training sections helped me A LOT! He patiently answered all my questions and also gave me a very detail walk through to QBO and I am very confident to work on my own books now! Thank you Luis!

Luis is a very nice, relaxed, professional. He took the time to understand my business and the challenges i was having trying to do my own books. He was responsive to my needs and very accommodating for scheduling. Very fast turn around time, especially for the time of season! As a small business owner, making sense of the books is a very troublesome task and time consuming! From here on out, ill leave it to Luis!

On point expertise and responsiveness! Luis helped my business with a time sensitive issue required to move forward with construction bonding. I explained the situation and he turned around in just a few hours, something we had been tooling around for multiple days trying to fix. Highly recommend him for your accounting needs. Sincerely,

Mario DeMatteo

Luis was so helpful in getting my horribly organized books all caught up and in working order. He is a Quickbooks wizard. I will definitely be using him for all my bookkeeping needs. Serrano Bookkeeping is also very affordable.

Doc Elliott

Luis was extremely helpful in getting my business finances set up in QuickBooks and in educating me on the basics of financial bookkeeping. I would highly recommend him and plan on using his services in the future.
