One of the most important things to remember when selling your handmade products at a craft fair is to record each and every sale that you make. It can be challenging to do this accurately around the chaos of customers and market noise, so a good way of doing this is to print out a inventory template before you go and tape it to your stall table right next to where you take payment.
Before you attend the craft fair, make a full inventory list of each product you are taking with you. It's a good idea to list multiples as seperate lines as this way you can just tick / cross of the line for each sale rather than update a quantity number. Alternatively, you can write in each sale as it occurs, however this approach is often a little more time consuming.
Once you return home, do a quick inventory stocktake to see if any loss has occurred and then update your actual inventory spreadsheet (or better yet, your handmade inventory management software like Craftybase).
