i have not seen an option for paying or selling/purchasing on credit/ to pay later when making a sale or receiving an item/ purchasing. I have only seen two blank options named Description, promise and details. You can design them to make payment, sell/ purchase on credit, add tax edit option, add discount option

I am waiting for you to make adjustments to the most vital features so that i can pay the USD 20 for installation of the V4.0.0 since I already purchased the license. Right now is V4.0.0 ready for installation ?

i love the black and blue very much!!
