Business in San Marcos
San Marcos had 94,833 residents at the 2020 Census and is a college town and an employment center for North County. The city's 2021 financial report lists the San Marcos Unified School District, California State University San Marcos and Palomar College as its largest employers, followed by Hunter Industries, United Parcel Service, Kaiser Permanente's medical group, Costco and Lusardi Construction.
Scalesight CPA's business address is in San Marcos, at 212 Ivory Gull Way, so this is home ground for us. The companies we meet here include contractors and trades that grew with North County housing, health and wellness practices, logistics and distribution businesses, and professional firms serving the area around CSUSM and North City.
Construction is a good example of why the books matter. Lusardi Construction is on the city's top employer list, and smaller general contractors, subcontractors and builders work throughout San Marcos and the neighboring cities. Their profit depends on job costing, retention receivable, percentage-of-completion revenue and the right accounting method for tax, all of which are easier to manage when the CPA preparing the return also sees the monthly numbers.

San Marcos CPA questions
Is Scalesight CPA located in San Marcos?
Yes. Our business address is 212 Ivory Gull Way, San Marcos, CA 92078, and you can call or text (619) 737-0268. Most work is delivered through secure online tools and scheduled video meetings, so clients across North County and the rest of the county are served the same way.

Yes. We set up job cost tracking, work in progress schedules and retention receivable so you can see margin by job, and we review whether your accounting method for tax still fits as revenue grows.
Do you work with health and wellness practices?
Yes. Clinics and practices need clean revenue reporting, payroll for providers, entity planning and often a multi-owner structure. We handle the books, the tax returns and the planning around owner pay.
