Predictable Revenue is considered canon for B2B/enterprise sales https://www.amazon.com/Predictable-Revenue-Business-Practice...

But not sure how applicable to agencies it is so YMMV.

Wow, thanks, I am glad that you found this useful. I wanted to edit some stuff and make it a bit more readable but the update form is a little crummy.

If there are any points I can clarify further let me know, thi s is a really off-the-cuff sketch and I had fun doing it and wouldn't mind digging a little deeper on some ares.

I am currently a developer in charge of growth at photoeditorsdk.com and about to crank on our inbound marketing. Although a very different market from your's we've had success with cold-emailing as detailed in [Predictable Revenue](https://www.amazon.com/Predictable-Revenue-Business-Practice...). The biggest boost came from preparing industry specific sales pitches & demos.

Cheers

Don't advertise, do lead-generation & sales.
