Each show day
1. Monitor stock levels (especially after day 1)
Be sure to keep an inventory of how much stock you have sold each day, and what you have remaining. Reassess at the end of each day if you have sold more than you expected and if you think you're going to run out of product, hopefully you're in a position to order more in. Or be prepapred with a back-up plan to take orders and offer delivery after the show.
2. The three minute staff debrief
3. Make a copy of sales leads (back them up)
4. Monitor and post to social media
5. Check your float
Ensure you have enough change.
