The project I am talking about is an online/offline payment solutions for Australia merchant. BPAY and PostBillPay is very popular to merchant in Australia. After this patch done, I will expand the project bigger and that would effect a lot of product of our company. This is including accept credit card and all will need PCI Compliance. None of Thai Banking doing this or very few.
This time, I will need to patching the invoice generator to fix the bug on the first of August. All the tests are good and believe tomorrow test will be good. I was on this problem for about 2 months already. The first month I have to fix the logic of wrong fee calculation and that was fixed. Now is the patch for the new invoice that will display the correct amount of fee that charge to clients.
Sometimes, working on financial stuff is too scared for wrong things happen, but after fix and test for many times that could make us confident for the results. Tomorrow too, I am very confident it would pass very easy.
