As per the post:
One of my jobs before owning a Mobile Home Park was Quality Assurance for Computer Software Programs (finding bugs in Computer Software).
I am in total agreement with @jo13nathan
"…Keep it cheap and keep it simple"
Computer Software is created by imperfect people (we all are) who make mistakes.
My Husband and I own 2 Mobile Home Parks.
We use Excel and Word to track payments and create monthly Invoices.
I like that Excel and Word are “tried and tested” software packages where you can keep your data on your own computer.
Personally, I am not a fan of computer software that “hosts” your data on their server.
What if you decide to leave them and go to another computer software program? Will you be able to export your data off the old software package and import it into the new software package?
We wish you the very best!
