For some treatments, for example, I need a fleece mask. Now I have to go through everything every day and remove it from my stock list as a consumer (and hope I don't forget anything.) Wouldn't it be useful to link your services to the option of your consumption? For example Service: neck-lift Consumption: 1 Neck lift veil When you then pay for that care, the mask is automatically removed from your stock. Hopefully I have some followers!! Bye!
