As a contractor, should I enter zero invoices to customers so that I can track expense even if they are not being billed for services like with maintenance agreements?

Depending on which version of QuickBooks you have, you can use job costing to track your expenses and then you can match them to invoices. If you want someone certified with quickbooks to help with your books my contact info is on my website aas-nc.com

To properly identify if you should be entering zero invoices for customers in a particular scenario, I'd recommend working with an accounting professional.

If you're in need of one, there's an awesome tool on our website called Find a ProAdvisor. All ProAdvisors listed there are QuickBooks-certified and able to provide helpful insights for driving your business's success.

Here's how it works:
 

1. Go to our Find a ProAdvisor page.
2. Use the City or ZIP search field to specify a location.
3. Select Find a ProAdvisor.
4. Browse through your results and find one that works best for the business. You can click on each ProAdvisor's profile to learn more information about them.
   
   

Once you've found an accountant, they can be contacted through their Send a message form:
 

1. Use the available text box to introduce yourself. Be sure to include details about which services you're looking for.
   
   
    
2. Enter your appropriate info in the Your name, Your email, and Your phone number (optional) fields.
   
   
    
3. Hit Send message.
   
   

You'll also be able to find many detailed resources about using QuickBooks in our help article archives.

If there's any additional questions, I'm just a post away. Have a lovely Tuesday!
