Many entrepreneurs overlook cash deductions, which could mean lower success rates for your bottom line. Little things such as tips to bell people on a business trip, extra baggage charges…even cash spent in tips jars at fast food restaurants can really add up. Keep an old-fashioned purse- or pocket-size notepad with you at all times for these small expenditures. There are great apps for your smartphone that will allow you to keep notes, etc., as well. You will be surprised at the deductions you have been allowing to slip through your system.
