This one seems pretty obvious, but you would be shocked at how many small business owners don’t properly track invoices and customer payments. If you’re not keeping proper records that you can make sense of at a glance, it could be months before you realize you have outstanding invoices. You could be collecting payments late, or missing some altogether. Make sure you’re properly tracking all payments due and recording when each invoice is paid, how long customers generally take to pay, and which customers you’ve had difficulties collecting payments from in the past.
