Bookkeeping and financials for a appliance repair company
Most appliance repair owners know their revenue and guess at everything else: margin per appliance type, what warranty work nets after the second trip, parts cost as a share of revenue, which tech's jobs are profitable. Those numbers decide whether to keep taking warranty claims at $55, whether the flat-rate book is priced right, and whether the third van pays for itself.
The mistake is doing the books once a year for the tax return, with parts, fuel and marketing lumped together. Working at two weeks: two months reconciled and a one-page report you can read in a minute.
