Maxime, I just had a long discussion with our Accountant. You are right. Product delivery location becomes the Second decision Point after partner jurisdiction. Third Point is tax properties of specific product. 1. Sell-able products: They have a customer from Quebec. This customer however comes to Ontario with their truck to pick up products. As a result they charge Ontario tax. It becomes customer responsibility to remit tax difference to Quebec government. Other Domestic Customers have products delivered TO their location. Tax is charged based on customer location. International Customers (to USA) are tax exempt. Also, this rule is product-specific. Products of our client are tax exempt. ERP have to be configured on product tax level. 2. Purchasable products: Domestic Suppliers deliver to client location. They all charge client tax (Ontario in this case). International Suppliers (from USA): Most Products our client is purchasing form US are NOT tax exempt. One Suppler is charging Ontario tax on invoice. They are registered with Ontario government and remit taxes them-selves. Another Supplier does not charge Ontario tax. As a result Ontario tax is charged at the border to the customs brokers. Broker later bills tax to the client. Conclusion: 1. It might be a good idea to document this logic somewhere, so when other people deploy and configure Canadian localization they can understand why thing set up this particular way. And they can change configuration to suite their needs. 2. For international suppliers consider charging tax exempt to province destination tax as a default. 3. Quebec seem to be made an exception on delivered to. You might want to add an explanation why. I can not devote more time to this issue today, I will have another look at the chart Monday, time permitting. So far it look good.
