Bookkeeping and financials for a auto repair shop
Marketing decisions get made badly when the books are behind. Owners look at the bank balance, see money, and assume the month worked. Then a parts invoice clears and the picture changes. Clean books give you the four numbers that govern a shop: gross profit split between parts and labor, effective labor rate, average repair order, and car count. With those current you can answer the only marketing question that matters, which is what a booked repair order costs you by channel.
Categorization is where most shop books go wrong. Ad spend, tools, sublet and shop supplies land in one bucket, and by March nobody can tell what the Google campaign returned.
Two weeks in, working means a P&L you can read in one sitting and a cost per repair order you can defend. Most owners find at least one recurring charge they forgot they were paying, and one channel quietly costing double what they assumed.
