Tesla Model Y Pricing Model

by

In today’s crowded used‐EV market, it can be nearly impossible to sift through hundreds of messy web pages and figure out what really drives a Tesla Model Y’s price.

Automate Amazon

Tracking and categorizing financial transactions can be tedious, especially when it comes to Amazon orders.

Amazon is so broad that a credit card charge could be for a digital or physical product, a whole foods purchase. The … Read more

Some tax-time automation

Most wealth is created by businesses making real products, but wealth can still accumulate from appreciating assets (real estate, land, gold, internet domain names, etc).
