    Kevin runs a metal roof installation business and has one subcontractor working for him. They work on household jobs only. They can install 50 square metres per day and Kevin charges an average of $45 per square metre (including materials).

    Income less than expected

    Joe has a metal roofing business with one employee. It has been a busy year due to storms in the local area. Joe worked 230 days in the year to fit in the extra work. On average he installed 50 square metres per day. He charges $60 per square metre for colour-coated steel and $50 per square metre for aluminium or zinc-coated steel.

    Joe's records show that he purchased 11,500 square metres of metal roofing. Two-thirds of the jobs completed used colour-coated steel.

    Using the benchmarks, Joe estimates income of $650,900 for the year.

    Joe's records show income of $575,000, which is less than he expected. He checks his quote book and finds several cash jobs which he has not included. This is an additional $75,000 in income.

    Joe recalculates his income for the year at $650,000, which is within the benchmarks. Joe is happy with his records but asks his bookkeeper for advice on keeping better records.
