The survey is historically conducted by mail. It is possible to respond by internet since 2013, initially via a fillable PDF questionnaire, and then from the ESA 2018 collected in 2019, via an online questionnaire proposed by Coltrane, the internet-based data collection system developped by Insee.
The annual data on the year N is collected in several waves between February and June of the year N+1 in order to take account of businesses' different financial year end dates.
