This explains why one of the major tier 1 suppliers has an absolutely horrendous workflow in processing financial data. We do a lot of business with them and when processing invoices sent to them, almost every division outside of Germany accepts invoices by email, but for one of the central German plants, they only accept invoices by mail to a foreign PO Box, so we're effectively giving a discount due to international shipping per each shipment/invoice can get high. As far as I can tell this seems more like an IT issue rather than a financial one (very large firms are geniuses in pushing out which vendors to pay, but if this was a universal case then every international plant would only accept invoices by mail)
