I can assist you in making the text in your invoice and quote descriptions displayed horizontally, Charltoncanvas.
I understand you have already expanded the description space to its maximum width, yet it still stacks vertically. That occurs when the Service Date and Product/Service fields are widened. To resolve this, we can adjust the width of the preceding spaces to fix the description column.
Please refer to the screenshot below for visual reference.

Finally, when your customer pays an invoice, you need to record that payment to balance your accounts.
