You’ve created your invoice, and now you need to send it to your customer for payment. Using MS Word, you can save the invoice as a PDF file then attach it to an email prior to sending. Smartsheet is a spreadsheet-inspired work management tool with robust collaboration and communication features. Its Google Docs integration and pre-built invoice tracking templates make it even easier to manage customer information, create, send and track multiple invoices at once, and quickly organize the details. Saving time saves your business money. An invoice is essentially a bill for goods or services, and the quicker it goes out the sooner you get paid. Include any taxes or shipping fees to reach the grand total. Depending on the size and scope of your business, you may not need invoice software to manage invoicing, especially since digital invoices can be stored in the cloud. Including a customer or sales number on your invoices can make them easier to track and help you stay organized. Columns allow you to include a service description, quantity or hours and pay rate. If you need to include sales tax, simply adjust the tax field to meet specific state requirements.
