Build a business bookkeeping and cash-flow operating system

Use dedicated business accounts and payment methods, document owner contributions and draws, and define categories that match how the company earns and spends. Save invoices, receipts, contracts, payroll records, tax documents, and financing agreements in a consistent system.

A chart of accounts should be detailed enough to make decisions without becoming impossible to maintain. Separate revenue streams, direct costs, operating expenses, assets, liabilities, and equity. Reconcile bank, card, payment-processor, loan, and payroll activity rather than assuming imported transactions are correct.

The income statement shows revenue, expenses, and profit over a period. The balance sheet shows assets, liabilities, and equity at a point in time. A cash-flow view explains why cash changed through operations, investing, financing, owner activity, and timing.

A sale can increase profit before cash is collected. A loan can increase cash without creating revenue. Buying equipment can reduce cash while creating an asset. Paying loan principal reduces cash and liability but is not the same as an operating expense. These distinctions prevent the bank balance from becoming the only report.

Build a rolling thirteen-week forecast beginning with available cash and listing expected customer receipts, payroll, taxes, inventory, debt service, rent, subscriptions, owner pay, and other obligations by week. Use conservative collection dates and update actuals weekly.

Track accounts receivable, accounts payable, inventory, customer concentration, gross margin, operating margin, and runway. The purpose is not perfect prediction; it is seeing a shortfall early enough to collect, negotiate, reduce, finance, or delay responsibly.
