A weekend bookkeeper works Saturday-Sunday shifts. In this part-time position, you track spending and receipts for a company, handle invoicing, create financial statements, reconcile expenses and income, and perform accounting tasks using spreadsheets or bookkeeping software such as Intuit Quickbooks. Your responsibilities vary depending on the needs of your clients or employer. If you work for a business, you may perform the bookkeeping tasks for the entire previous week on the weekend. If you work for a company that operates on Saturday and Sunday, you perform daily bookkeeping duties for those two days.
