• Input benchmark – roof guttering

    Businesses in this industry install roof guttering. Other services may include the repair and maintenance of roof gutters.

    These input benchmarks have been developed in consultation with the Metal Roofing and Cladding Association of Australia.

    They represent the industry norm and apply to roof guttering installers who work directly with household customers and are responsible for purchasing their own materials.

    These benchmarks are current as at April 2015.

    Input benchmark example

    Example

    Mark has a roof guttering business with one employee. He does household work only, including extensions and replacement of old guttering.

    Mark installs both aluminium or zinc coated steel and colour coated steel guttering and charges an average of $50 per metre. To be competitive with other businesses in his area, Mark offers discounts for customers paying in cash.

    Mark uses his bank statements to record income. His records show income of $255,000 for the year. This is less than the benchmarks, so Mark decides to review his records.

    Purchase statements from his suppliers show that Mark purchased 11,000 metres of guttering. Using the benchmarks, he estimates his income should be around $550,000.

    Mark checks his diary and finds several cash jobs which he has not recorded. This is an additional $250,000 in income.

    Recalculating his figures, Mark has income of $505,000 for the year. This is within the benchmarks and accounts for cash discounts offered to some friends. Mark is confident that he has recorded all income for the year. However, he asks his bookkeeper for advice on how to keep better records so that he has all the information he needs for his next business activity statement.
