I wrote for them too. My book was published last May.

I made a similar workflow to you. I wrote using vim and markdown, then used pandoc to convert to HTML. I then wrote some scripts to mangle the HTML to something more compatible with Packt's system (adds some class names and the like).

Regarding sales, they send me royalty statements for each quarter about 3 months after the quarter's end. For example, my book was released in May. I didn't get my first statement until the end of September. My last statement is dated Dec 31st, and it covers July-September 2019.

You can also setup an Amazon author account and get Amazon sales numbers much more quickly. Just go to https://authorcentral.amazon.com/ and create an account. You'll then have to verify that you're the author of your book, but it's pretty straight forward.

I had already set up an author-central account on amazon.co.uk but it seems like sales info (looks like it's US-only) is only available if you also sign up for an author-central account on amazon.com
