What is monthly bookkeeping?

Monthly bookkeeping means recording every transaction, reconciling every bank and credit card account, and closing the books once a month so your financial reports are accurate and current. It's the ongoing work that keeps a business ready for tax time, loans and day-to-day decisions.

Monthly bookkeeping is the core of what Momentum Bookkeeping does. Each month Jennifer records and categorizes your income and expenses, reconciles your bank and credit card accounts, and closes the month with reports you can read.

You work with the same person every month. Jennifer learns how your business runs, notices when something looks off, and tells you in plain language instead of leaving it for your CPA to find in April.

Monthly Bookkeeping questions

How is monthly bookkeeping priced?

You get one monthly price after a free consultation, billed month to month with no long-term contract. The price depends on how many accounts and transactions you have and how complex the books are. Extra work outside the agreed scope is billed at an hourly rate.

What do you need from me each month?

Access to your bank and credit card accounts, receipts or notes for anything that needs explaining, and answers to a few questions when a transaction isn't clear.

Do I need a bookkeeper if I already have a CPA?

Usually, yes. A bookkeeper keeps the day-to-day records accurate all year. Your CPA focuses on tax strategy and filing. Clean monthly books make your CPA's work faster.
