This made me laugh so thank you, but in all seriousness, we started by working through the lifecycle of a customer from the top and push it to the end. The first part being, how do you meet and qualify a new client, to the last part where you're handling paystubs and invoicing clients.

There are a ton of things I wish we handled better, particularly on-boarding where although it's self-serve, it needs work, but we did figure it's better to launch and learn from more users before building more software.

The second thing was we used the product itself to onboard (vip.epihub.com/reserve), and again once we were users, we kept pushing until it worked well enough for us to train people on how to use our product.
