Vacation Rental Management Software
I am currently earning the majority of my income from managing two vacation rental properties.  When I first started in the business in 2008, there were no good, online tools for managing my business, so I built my own.  Since that time, the websites which offer the primary marketing channels for homes like mine have included a system on their backend, and while it meets many basic needs, it also lacks in many ways, especially when it comes to managing multiple properties in one profile.  I'm in the process of commercializing my software.

Rental Management Software
I own 8 rental properties and managing and keeping up with those is a lot of work.  Most landlords use a combination of manila folders, scanned documents, word, excel, email, and an accounting system (manual or electronic) to manage their businesses. It's a lot to manage and many folks have some custom needs.  My goal will be to provide one online management tool that greatly simplifies this process and centralizes information.  For those that want it, the software may also have its own accounting module (final determination on software module is pending, see more on accounting software below).

Payment Processing System w/ Invoicing  (Virtual Terminal w invoicing)
Paypal and PaySimple (along with several others) offer ways to send and receive money and varying levels of invoicing.  Each has nice features.  I had systems prototyped in 2005, but got sidetracked. My goal is to build a stand alone system similar to those but addressing specific needs of small businesses...and while that is nothing novel, I want to modularize that system in such a way that it can be seamlessly integrated into other small business software applications of mine and others very quickly (like the rental management packages above and the accounting software and pet sitting software below) so that it is contained within the same software framework and it looks and feels like a part and parcel of the independent program.

Accounting Software
Quickbooks and Quicken own the small business accounting market.  In ~2003 my needs for flexible, small business accounting software were skyrocketing, and I found Quickbooks to be expensive (constant upgrades), cumbersome, and bloated.  At that time, I wrote web based accounting software from scratch, and  I've been using that software in various versions since 2004. 

Pet Sitting Software
There are plenty of pet sitting software solutions out there.  I have an associate who has a pet sitting business and is currently using one of the web based industry solutions.  I am planning on building a solution for them, and the intention would be to have them market it and sell it to others once we've built it as we'd like it.  It's a competitive field, so it would take good marketing on the site, but that's all part of capitalism.

Litigation Publication Software
This project has a very personal, and special place in my heart.  This project was inspired by a contracting vendor who I had a longstanding relationship with who didn't treat me well when we discovered some major flaws in their finished work years down the road. I invested a lot of money in a lawsuit that I had to drop due to economic futility from their  'vigorous' defense of utter nonsense.  I am really looking forward to the day I can share the Technological Art I've created with their video taped testimonies....this one is personal.
