Certified Public Accountant services for La Mesa's manufacturing and software sectors come through Jodienne E. Gresens, CPA, a sole-practitioner firm on 68th Street operating since 1984. The practice prepares sales and use tax returns under California Department of Tax and Fee Administration rules for product-based businesses, compliance work that dovetails with the commercial liability coverage structured by Business Choice Insurance Services. Service lines span personal and business income tax returns, California sales and property tax filings, quarterly payroll processing, and monthly bookkeeping reconciliation for small businesses across San Diego County. Industry-specific experience in manufacturing cost accounting covers raw material inventory valuation, work-in-process tracking, and cost-of-goods-sold calculations under both FIFO and weighted-average methods. Software company engagements require capitalization-versus-expense analysis under ASC 350-40 for internal-use software development costs, a technical distinction that often accompanies the IT infrastructure consulting provided by DSI Development. Highest-tier engagements involve multi-entity consolidated reporting with intercompany elimination entries, depreciation schedule reconciliation across MACRS and California-specific recovery periods, and Form 100S S-corporation apportionment calculations.
