Great to work with

"I make and sell surf boards, working with Alethea has always been super smooth and she’s always very helpful and quick to respond. With my business there’s tons of paper work with expenses, sales and tax prep and she’s always been super good at giving me reports when I need them and help t me be ready for tax season early if not on time!"


Great customer service, very knowledgeable

"I came to Ten Key about a year ago and still am shocked the amazing impact they made on my business. I was struggling with organizing back of the house I’ve always had a creative mind but could never organize and utilize the tools needed to run a business. Right away they responded and set up a meeting to go over my paperwork, and I felt like we already were family. Comfortable space to ask questions and trust them with this information. They offered to come in and show my team and I how we can upkeep our accounting softwares. Thanks to them I’ve been more confident running my business and feel now I can focus on my business!! Would recommend to anyone who was in the same place I was a year ago."

Organized, professional, and reliable

"We could not be more impressed with Ten Key Accounting! Alethea has saved us time and money with her knowledge and skills. She keeps track of our thousands of inventory items and many transactions each day. Alethea's attention to detail has allowed us to spend more time on growing our business and not on our books."
