Bookkeeping notes
What the books look like for Greenwich businesses like these
Medical and health practices
Insurance payments, patient payments and write-offs are reconciled separately, so receivables are never guessed. Payroll, supplies and equipment financing are tracked monthly. We work from your accounting records and never need patient clinical information.
General bookkeeping practice, not tax or legal advice.
Beyond the books
From records to decisions
Records tell you where the money went. A business in Greenwich 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.
Think of it as part-time finance leadership: forecasting, budgeting and a monthly conversation about the numbers. It depends on the bookkeeping underneath. Tax filings, audits and legal advice stay with your CPA or attorney.
What that can include
- Seasonal cash planning for the slow months
- Pricing and margin review by job, product or customer
- A rolling 13-week cash flow forecast, so a slow month is not a surprise
