A short discussion with Ms. Katrina of Pottery Barn regarding of their billing process. Which are the following: 1. They only received SOA excel and pdf files from Chin(WS Singapore) 2. Check the validate the excel file if the data is correct based on the what they ordered and received. 3. They will send the file to finance to also validate for billing. 
Basically there's no any data integration will happen here this is more on their internal process betwee merchandising and finance department.
