Automatic tax rate for each product line

Automatic tax rate for each product line

Helo,

i bought today 30 days professional Zoho Invoices subscription to migrate our invoicing system but i discovered something incredible. If i make invoice with 15 products lines for example i must for every line choose the tax rate. We are selling only 20% TVA products, it's crazy do say to my collaborators "listen everybody, from today you must make hundreds clicks to check the tva rate for all product. If you forget some, you must make a Credit note and recreate a new invoice to correct this mistake". They will laugh and forget about the soft. 

It's just unreal, maybe somebody knows how to make this default tax rate? We are using a simple NCH invoicing product and there is no such of problems. 


If there is no solution i hope Zoho will refound me :))


Thanks
