Getting references after a company closes, quality inspector here

I worry a reference will only confirm dates of employment. Any experience at all would help. I have one former client who liked my work. How do you ask politely?

Keep everything in writing and save the confirmation numbers. It made the follow-up calls so much easier.

Thanks for writing this out. I went through something close to it last year, and it settled down once I kept a simple log of every call and form.
