My father once told me “life is about options” and to summarize his wordy anecdote the point is to not limit your options in any way by avoiding to do the simplest things.
So, stop keeping inaccurate books…seriously.
Having 100% accurate books paired with a billing system DOES matter and it with good books you drastically impair your businesses ability to recover these funds from your debtors. Don’t limit the options of your business because there is hidden potential in those unrecovered dollars.
If your accounting system is terrible you need start today to find something better. Every day that records go unkept means money you don’t know you have earned or money you can’t prove you have earned going into a black hole.
Accounting systems aren’t always as pricey as you think and in the long run you are better off paying to know where you stand than flying blind. You are better off keeping your options open because even the best collections solution can’t collect money you don’t know you are owed.
