To create invoices that convert to cash, follow these simple recommendations to make each invoice a valuable tool for your business. 

Writing Tips for Invoices

Use invoicing to keep a detailed record of the products and services that you provide. There’s no such thing as too much information on an invoice because if you are looking for information weeks, months, or even years later, you will wish that you had all that detailed information. 


Your invoices should be sent either right before or directly after services/products are rendered. If you leave too much time between the product/service and billing for it, your invoice might get forgotten. Invoices should also include as much information as possible

Depending on your client agreement and invoicing software, you may be able to set up recurring invoicing that automatically sends invoices at the same time each month. This works really well for retainer clients and ongoing projects. They know when to expect it and you can keep your focus on your work. 

You have the power to determine the payment terms for your invoices. You can choose “due upon receipt” or 7, 14, or 30 days later (30 days later is referred to as net 30 in many bookkeeping and invoicing software). Be sure to declare on the invoice when the invoice is due and if there will be any late fees after x-amount of days.

When you start invoicing, you need to look at what information is on your invoice. Each piece of information serves the purpose to keep you and your client informed of the work completed and payment terms.
