Off-the-shelf software is available immediately so the shopkeeper can benefit straight away from the money spent on the software.
Off-the-shelf software is tried and tested and therefore is less likely to have bugs and errors than custom made software.
Development costs are shared by all the people / businesses that buy it so it cost much less than commissioning custom made software.
