On app.invoicing.co I use line item taxes, not per invoice tax, and previously each line item would already have the tax applied (not labor items). Now I have to manually pick the tax for each item.
If I edit the item on the Products page, the correct tax is set there.
For a while every line I entered would already have the tax applied correctly. Now I manually set tax on each item, save the invoice, create a new invoice, and the same item has blank tax again.
Yes, I think my settings have the correct Line Item tax rate enabled, and at one point it was doing exactly what I expected, not sure if it was based on last used behavior, ie last time I added that product with tax, so next time it will have tax. So that every time I added an item the tax was already applied on that line, it gets tedious when you have several items on an invoice… some get missed and the invoice gets sent with wrong tax collection.
