I would focus 80% of my efforts on sales/marketing. Given my background specifically in sales I would recommend the following books specifically:

Selling to big companies - jill conrad
Adanced selling strategies - brian tracy
Question based selling - tom freese
Ultimate marketing plan - dan kennedy
Influence - cialdini
Effective executive - drucker
3G Way - fransisco de melho
True Power & Daily Work Routine Management - Falconi

By no means exhaustive, and there are a ton more, but these have helped me immensely. Best of luck.

Excellent Question! I would start with The E-Myth by Michael Gerber. Quick read and helps you frame your mindset for Small Business success, which is very different than large organizational approaches. For folks coming from a large organization/corporate background, it is very helpful. Best, Graham

Great responses above, but I'd also be doing some calls w/ experienced folks who sell products similar to your company's products. Sales is a contact sport and often the best teacher is experience. Same is true for leading a sales team. Doing your best to find "safe" practice w/ some trusted advisors may be a helpful complement to these books. Good luck!

Great question & I'm glad you asked it so I could receive the responses as well as I'm hoping to finalize a purchase agreement on a B2B company this week. I'm also trying to find books on how to incentive employees so that performance maintains and exceeds its current levels if you hear of any! I just bought "How I raised myself from failure to success in selling" by Frank Bettger and so far I am enjoying it.

Effective human / mission leadership precedes any domain specific skill set IMO. I recommend The Advantage by Patrick Lencioni. No need to apply verbatim. Focus on understanding and applying the principles. It's is pretty much a leadership manual.

And there is "Raving Fans: A Revolutionary Approach to Customer Service", the counter intuitive quick read classic by Kenneth Blanchard. Repeat business is the key to successful B2B return on sales investment and that is what this book is about.

Love all the suggestions. Thanks everyone!
