Bookkeeping notes
What the books look like for Boston businesses like these
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.
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
Books show last month. Planning looks ahead
Clean books answer what happened last month. Owners in Boston 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.
The idea is simple: finance help on a part-time basis, built on current books. We coordinate with your CPA or attorney for anything that needs a license, such as tax returns, attest work or legal questions.
What that can include
- A rolling 13-week cash flow forecast, so a slow month is not a surprise
- Hiring and equipment decisions modeled before you commit
- A one-page dashboard of the five or six numbers you steer by
