You can track expenses as a self-employed person the same way that other small business owners do—either manually, or by using accounting software.There are many benefits to using an accounting software solution like LZ Books, such as automatically separating personal and small business transactions, and auto-categorizing business expenses into tax-ready categories, which can help you maximize tax deductions. There are also invoicing features, like the ability to customize and send unlimited pay-enabled invoices to clients; and other accounting features such as income tracking and trends, to help you run your business more easily.
