Firstly congratulations to Pinksheep (1st) and Quikfire (2nd), As well as wining 3rd place in the KashFlow invoice design competition I am now a featured KashFlow API developer (you can find me on the KashFlow site here).
This is what KashFlow had to say about my design
This invoice stands out immediately with the business logo and colours a clear part of the design element. The distinct box style they use clearly shows what the customer is being invoiced for, the rate for the service and the total price. Our favourite element? The range of payment options detailed at the bottom of the invoice.
