FAQ Q193: Why is the sales tax (VAT) not added to the price quoted to the clients?
The sales tax should be included in the prices you set up in Pricing Manager. If you use Planyo for invoicing, the sales tax will be listed on the invoice separately. If you don't use the invoices in Planyo, the sales tax setting is not used.
If you don't want to include prices with tax into Pricing Manager because you prefer working with net prices, simply include a rule at the end of your pricing manager which will always add the tax (rule Always true with values like +8% if the tax is 8%). This way the prices you enter will be without tax for easy modifications but you'll still comply with the way prices work in planyo.
