To properly identify which general ledger accounts are affected when an invoice is produced, 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.
Use the City or ZIP search field to specify a location.
Select Find a ProAdvisor.
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:
Use the available text box to introduce yourself. Be sure to include details about which services you're looking for.
Enter your appropriate info in the Your name, Your email, and Your phone number (optional) fields.
Select Send message.
