Payroll, supplies and equipment financing are tracked monthly. We work from your accounting records and never need patient clinical information. ### Contractors and trades Materials, subcontractors and labor are coded to the job, so each job's margin is visible before the next bid. Deposits and progress billings are recorded as they happen, and 1099 details for subcontractors are collected up front. General bookkeeping practice, not tax or legal advice. Beyond the books ## More than books: planning and cash Records tell you where the money went. A business in Westchester County that is growing, carrying debt or running tight on cash also needs to know where it is going, and when a slow month will hurt. Fractional CFO support is a few hours a month of senior financial attention instead of a full-time hire. It sits on top of your monthly books. For tax returns, audits or legal questions we work alongside your CPA or attorney, and we are not a CPA firm. ### What that can include - Pricing and margin review by job, product or customer - Seasonal cash planning for the slow months - Hiring and equipment decisions modeled before you commit [What a fractional CFO does →](/bookkeeping/guides/what-is-a-fractional-cfo) State filings ## What the state expects from businesses in Westchester County, New York Recurring state report Biennial Statement, filed with New York Department of State, every two years.
