These are the pros and cons of selling spreadsheets. The real beauty in this idea is that you could do the work once and there is no limit to how much you can earn, especially with effective use of the internet and other mass communication tools.
On the other hand, to hire and permanently maintain a team in charge of creating the right spreadsheet solutions for your business would be very costly. Added with the costs of regular spreadsheet-generating program purchases, the costs involved by forming and keeping a well-trained team of spreadsheet designers in your company can generate considerable financial losses to the business you are running, especially when you are the owner of a struggling micro-business. To eliminate the problems behind spreadsheet designing, the best option is to purchase high-quality ready-made spreadsheet solutions from a specialized, reliable provider.
You can build a reputation as an expert spreadsheet developer. This certainly doesn't hurt the resume. Using Excelville.com to sell spreadsheets allows you to set up a profile with your work, biography, and other info that certainly makes for good conversation material during interviews.
