I'm trying to set up Sage for my new business, and it won't let me continue without an HST #. I'm still waiting for my incorp docs to finalize and don't yet have the number. Does anyone know how hard it is to add a GST # later, if I indicate that I don't need an HST during start up? I want to get going with my chart of accounts, but don't want to cause myself grief down the road.
