Hello there, @NathanH.


Let's perform some troubleshooting steps so you can save a bill successfully.


There are times that the browser keeps either too many or outdated Internet files that may cause websites, like QBO, to act weirdly. To isolate this, let's try logging into your QuickBooks account using a private browser. 


To use a private browser, here's how:  


  • Google Chrome: Ctrl + Shift + N
  • Mozilla Firefox: Ctrl + Shift + P
  • Internet Explorer: Ctrl + Shift + P
  • Safari: Command + Shift + N

Once logged in, go back and try to save a bill again to double check. For your reference, you can check out this article for further guidance: How to Enter and Pay Bills.


If it works, we'll need to clear your browser's cache to optimize the browser's performance and your QBO experience.


If you get the same result, let's try using a different browser, then try to save a bill from there.


Please feel free to get back to us if you have any other questions. We're always here to help.

Re: Unable to load[removed]439/purchsales/save status: 400

Hi there,

I had the same error message when trying to change sales tax on an invoice and then click save, it did not allow me to do it. Somehow I figured out, here is what worked for me hope it works for you.


I open the invoice and then BEFORE change the sales tax amount, I clicked on an empty row amount as if I was going to add an amount, then I went to change the sales tax amount, and then I clicked save and could save successfully.


Hope this helps... :)

Thanks for looping in, Paloma.

Welcome to the Community!


Good to hear that everything is working fine on your end. I appreciate the details you've provided and for trying to resolve the issue.


The information you posted will definitely help other customers who may have the same concern. However, allow me to provide the step-by-step process in creating new invoices to better isolate the issue.


To create an invoice:


  1. Select the Plus icon (+) on the Toolbar.
  2. Under Customers, choose Invoice.


  3. Select the name of the Customer from the drop-down list and enter or verify customer information.
  4. Select the Terms for the invoice from the drop-down list. The terms indicate when you expect payment for the invoice.
  5. Verify the Invoice date and the Due date. By default, the Due date is set 30 days after the Invoice date, but you can change either date as needed.
  6. Select the item or service being billed for from the drop-down list in the Product/Service column, and enter information about the item, including the Amount and any Tax.
  7. Specify any applicable Sales Tax Rate or Discount in the appropriate fields.
  8. Select Save and send to create and preview an email to send the invoice to your customer, or Save and share to create a link to the invoice you can email or text to your customer. Alternatively, you can select Save and new to save your work and start a new invoice, or Save and close to save the invoice and close the screen. You can select Save at any time to save your work without leaving the invoice.
