I am in the middle of developing an app. I'm having some trouble trying to decide the best usage for two features in particular. I know what both of these words mean, but I am becoming increasingly confused and irritated the more I try to find a good-fitting word for both features that is not only easily understood by your average Joe, but also doesn't sound too weird or out of place.
The reason I am becoming confused is because I was originally using the word Expense to allow you to enter things like Grocery Shopping items, utility bills, petrol, lunch, dinners, etc.
But then I wanted to make things a little easier. I wanted to separate necessities, or things that we really need from things that we want - or just simply one-off purchases. So then I introduced the word Purchase. So now I have a menu that looks like this:
You click on New Purchase if you've just bought something and want to record it (this is a budgeting app). You click on New Expense if you have things to pay for like bills, petrol etc on a regular basis.
I'm not sure anymore. I've confused the heck out of myself and now I need some help.
Which word would best describe the feature: "I just purchased something and need a record the details of this transaction" (Please don't suggest using the actual word Transaction. That word is literally everywhere else.)? And which word would best describe this feature: "I have some bills and/or items that I buy on a regular basis, and I want to record the details of these future transactions."?
Remember: I'm trying to keep them separate. I know I could just use one word for both features, but due to many minor differences in each feature it could be confusing to others and I like a nice and clean interface.
