Keep business and personal activity separate
Use dedicated business bank and credit-card accounts whenever practical. When personal and business transactions are mixed, bookkeeping becomes slower and it is easier to miss income, misclassify expenses, or create unsupported owner-loan and equity balances.
Core records to organize
- Bank and credit-card statements, along with records identifying the business purpose of transactions.
- Sales reports, payment-processor reports, Forms 1099, invoices, and other records supporting gross receipts.
- Receipts and invoices for significant expenses, equipment, repairs, supplies, insurance, and professional fees.
- Mileage or vehicle-use records when a vehicle deduction is claimed.
- Payroll reports, Forms W-2 and 1099, contractor information, and payroll tax filings.
- Purchase documents for equipment, vehicles, furniture, and other assets, including financing records.
- Loan statements and documents showing new borrowing, repayments, and owner contributions.
Do not wait until tax season to clean everything up
Monthly reconciliation lets you find duplicate transactions, missing deposits, uncategorized expenses, unusual balances, and payroll differences while the information is still fresh. Clean books also make tax projections and business decisions more reliable.
