Bookkeeping notes
What the books look like for Long Island businesses like these
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.
Professional offices and consultants
Invoices are matched to payments so open receivables are accurate, client retainers and expenses are kept apart, and owner pay is recorded the same way every month. Monthly reports show real profit after the owner's own costs.
General bookkeeping practice, not tax or legal advice.
Beyond the books
Beyond the books: fractional CFO support
Clean books answer what happened last month. Owners in Long Island who are hiring, borrowing or planning a bigger year usually need the next layer too: a cash forecast, a budget they can track, and a short monthly review of the numbers that matter.
It is planning and reporting on the books we keep, delivered at the size your business needs. It does not replace your CPA. Tax returns are a separate service (see /tax-preparation); we do not audit statements or give legal advice.
What that can include
- A rolling 13-week cash flow forecast, so a slow month is not a surprise
- Financial statements and a package built for a bank or lender
- Loan, line of credit and payoff scenarios
