If you’re running an accounting business, at this stage your customers would be evaluating different potential service providers. They might need resources like pricing guides (so they know what ballpark rates are), how to evaluate the landscape of accounting services (i.e. whether to hire a solo accountant, an agency, etc.), or how to choose an accountant.
As a software engineer myself, I can tell you that building funnels from an application standpoint takes massive amounts of work. There's a great deal of coding and integration that's required here. From email systems to landing page implementations to credit card processing APIs, and everything in between, so many platforms need to "talk," that it takes the bar too high for the average marketer.
