QBO suppliers can only have one currency, and unless we edit the supplier name there is no way to identify what currency the supplier is set up as in Dext. If the transaction currency chosen doesn't match the supplier currency, QBO will do an automatic conversion when it publishes which then requires manual fixing.

If Dext would just display this currency (and also identify if a different one is chosen!) it would reduce the currency errors.

Setting a supplier rule doesn't totally fix it given the currency can be over-written, and often we will have multiple versions of a supplier in different currencies, and Dext will inevitably pick the wrong version (e.g. Starbucks - CAD vs Starbucks - USD).
