Hi magsyardworks,
QuickBooks Online offers so many awesome tools that help you get your business bookkeeping done in a breeze. I know it's vital to ensure your customers are receiving accurate invoices, and I want to make sure you're able to get back on track with this. I'll offer some helpful troubleshooting tips that should get this resolved, and where to go for further assistance.
Emailing your invoices directly from the program is one of the best ways to save time. It's always a good idea to preview your invoice emails before sending them to your customer.
The first step is to check your account's settings. You may notice that you've turned on "Automatically apply credits". If your customer has any outstanding credits, this setting will automatically apply it towards their next invoice.
That may explain why you're seeing a different total when you email the invoice via QBO. You can double check on your settings by clicking the Gear icon > Account and Settings > Advanced > Automation. If you have this setting turned on and you want to turn it off, click the small pencil icon to make changes.
If you don't have this setting turned on and you're still running into issues with your emailed invoices, perhaps there's a browser-related problem causing discrepancies. Try clearing the cache and cookies in your browser to remove any stored Internet files that may have built up in the background of your browser. Here's how to do that: Clear cache and cookies to fix issues when using QuickBooks Online.
If the issue persists, try using an Incognito window in Google Chrome. This is a private browser that doesn't get impacted by cache and cookies. Here's how to do it: Browse in Private. You should also try using a different browser all together.
If you're still experiencing this issue after following these troubleshooting steps, please touch base with our tech support team directly so an agent can investigate this further for you.
Have a great day.
