GGS Advisory is a bookkeeping and small business CFO firm right here in the East Valley. We help Mesa business owners keep clean books and know their numbers. You focus on your work and your family. We watch the money.
Mesa is the third largest city in Arizona, and it runs on small business. From downtown Main Street to Dobson Ranch, Las Sendas, Red Mountain, Superstition Springs, and Eastmark, thousands of owners keep this city moving. That is exactly who we built this page for.
Home-based businesses
You sell online, coach, consult, or create from your home office. We keep your books clean and tax ready, so tax time is not scary.
Contractors and home services
You serve homes from Dobson Ranch to Las Sendas and out toward Red Mountain. We track every job, so you know which jobs make money and which ones eat it.
Realtors and agents
Commission checks jump up and down. We smooth out the picture, so you always know where you stand and what to set aside for taxes.
Shops, salons, and studios
You run a storefront near Superstition Springs, downtown Mesa, or the Fiesta District. We handle the daily money mess, so you can take care of your customers.
What We Do
Three ways we make your money life easier.
Step 1
Monthly bookkeeping
We record everything, match it to your bank, and send you a simple report every month. You always know what came in, what went out, and what is left.
Step 2
CFO advice
We hop on a call and read your numbers together. You leave with a plan for cash, pricing, and profit. It is like having a big company CFO, sized for your business.
Anytime
Catch-up and cleanup
Books behind? QuickBooks a mess? We fix it and get you caught up fast. Then we keep it clean going forward.
We are based right here in the East Valley. We know Mesa and how local business runs. Your books, reports, and check-ins are always a text or a quick call away.
You text a person, not a ticket.
No call centers and no support queues. You text Erick, and Erick texts back. It is that simple.
Trusted with big events.
We run event accounting behind the WM Phoenix Open, an event that welcomes more than 700,000 guests. If we can keep those numbers straight, we can keep yours straight.
Big firm training, small business pricing.
Our founder trained in tax at KPMG, one of the largest accounting firms in the world. You get that skill without the big firm bill.
