3. Document and file receipts
Keep copies of all invoices sent, all cash receipts (cash, check, and credit card deposits) and all cash payments (cash, check, credit card statements). Start a vendors file, sorted alphabetically, (Staples under “S”, Costco under "C,"etc.) for easy access. Create a payroll file sorted by payroll date and a bank statement file sorted by month. A common habit is to toss all paper receipts into a box and try to decipher them at tax time, but unless you have a small volume of transactions, it's better to have separate files for assorted receipts kept organized as they come in. Many accounting software systems let you scan paper receipts and avoid physical files altogether.
