Amazon specialists.
Jones & Cosman is one of a small number of Canadian accounting firms that hold Official Amazon Service Provider status. That means Amazon has vetted us as qualified experts for their seller community.
We have been serving e-commerce sellers since 2012. We're sellers ourselves, and we understand how your business works from the inside.
Whether you sell from Canada or into Canada as a non-resident, see how our Amazon seller accounting brings bookkeeping, tax, and GST/HST under one roof.
