Some other sample invoice where all you need to enter is a description of work and amount billed. You have to manually add lines and tax to calculate total. Marketing banner in the footer of this invoice allows you to advertise other services your company provides.
It does not get any easier than this. A simple invoice is ideal for small businesses or individuals who want simplicity and flexibility. Enter a service description, calculate the total, and you’re done. If you don’t need to charge tax, just set the tax rate to zero percent.
