I always hated the business side of being in business. After a hard day’s work, we would retire to our home office to do billing, write checks and fill in the books. Truth be told, Lois did the bookkeeping for the most part. No computers in 1979, so those tasks were done by hand.
Today, of course, there are several very good bookkeeping computer programs, but for the small PHVAC shops, many still find themselves working after work just to keep up.
