Perhaps I can follow up on that idea. Canada Post currently is the only organization allowed to deliver mail under 500 grams. This has come up repeatedly in terms of invoicing companies B2B, and invoicing their membership. Out west it's very common to do electronic invoicing, especially for business. The Chamber of Commerce in Calgary does e-invoicing for all the membership dues. At the organization I used to work for, with 6,000 members, we used to e-invoice.
Is that something your organization does?
