In completing this arduous task on behalf of our dear friends at Revenue Canada, we also discovered a substantial number of carriers who have ceased to exist. Along with those who have moved, amalgamated with another entity, flat out changed their name, provided an incorrect business number, and a host of other time consuming and troublesome inconveniences. The only saving grace to this ridiculous exercise, is that with better record keeping now in place, next years filings should be somewhat less time consuming . We have also installed a new wrinkle to our payables process, any invoice received without a current business number displayed is returned to the supplier.
