According to the saying “better now than never,” any time during a fiscal year is suitable for introducing statistical inventory sampling. However, since the initial effort in the year of implementation is slightly higher than in subsequent years, it is advisable to begin in the first half of the fiscal year. It is also helpful, for example, to conduct a trial statistical inventory sampling early on to determine whether the quality of inventory records is sufficient or whether adjustments are still needed to ensure a successful implementation.
Many companies also schedule their annual inventory in the first half of the fiscal year, allowing them to begin preparations and execution of the statistical inventory sampling starting from the third fiscal quarter.
For example, if the fiscal year ends on December 31, the period from February (after the annual accounts) to May/June (before the summer break) is particularly well suited for introducing statistical inventory sampling and conducting a trial run. For other fiscal year-end dates, the ideal implementation period can be determined accordingly.
