Which name should I provide on a dealer account form? Company name or trading name?
Congrats for contacting your suppliers and receiving dealer account forms! It sounds like you're well on your way to getting this supplier signed.
If they haven't specified whether they want your company name or trading name, you can just enter your company name then follow that with T/A (trading as), then your trading name.
That way you give them both and make it clear which is your company name and which is your trading name.
