How on earth can I design an invoce that allows a narrative detail of services offered?

Consider having an additional app with an engagement letter feature to explain your offer in more detail and options to choose from, if any.

Hi 1231 4571 9921 612H, you can edit the width of the columns by going to the Cog > Custom form styles > Edit > Content > Click the middle section of the invoice template > Edit labels and widths > Toggle the slider. You may also wish to remove some of the columns by unticking the checkbox beside the column heading, to allow for more space for each column. 👩‍💻
