Confirm workshop attendance before ordering materials

Ask them to let you know as soon as possible if their plans change. If you have already ordered materials, you might have one extra set, which you could offer to someone else or keep for a future session. If the withdrawal happens before your order deadline, you can adjust the quantity. Make it clear when you first ask for confirmation that you need to know about any changes promptly because you are committing to a specific number of supply sets.

Give at least one week if possible, especially if people need to rearrange other commitments to attend. State a clear day and time when confirmations must be in, and explain that this is the cut-off for ordering materials. If your workshop is on a Saturday, asking for confirmation by the previous Friday gives you the weekend to place an order. Shorter notice works if everyone already knows about the workshop and just needs to give a final yes or no.

Only if you can afford the waste or will definitely use spare sets later. Ordering exactly the number confirmed avoids spending money on unused materials. If someone asks to join after you have ordered, explain that materials are already purchased for confirmed participants only. You can offer them a place at a future workshop instead. Some organisers add one spare set as a safety margin, but make clear during confirmation that late joiners cannot be accommodated.

Send a brief reminder message to those specific people, stating that you need their answer by end of day or you will assume they are not attending. Explain that you are ordering materials and cannot include them unless they confirm. If they still do not reply, leave them out of your count. You can mention in your reminder that if they later want to attend, you may not have materials for them. This usually prompts a quick response.

Treat maybe as a no for ordering purposes unless they give a firm yes by your deadline. Send them a direct message explaining that you need a definite answer to order the right quantity of materials. Let them know that if they confirm yes and then cannot come, you will have an unused set, so you need genuine commitment. Most people will either commit or decline when they understand the practical consequence. A probably is not enough to spend money on supplies.

You can, and a deposit often encourages firm commitment because people have a financial stake. Explain when you ask for confirmation that a small deposit holds their place and covers the cost of their material set. Agree a date by which the deposit must be paid, and state clearly whether it is refundable if they cancel before your ordering deadline. Collecting money adds extra coordination, so only do this if no-shows or late cancellations have been a problem before.

Move your confirmation deadline earlier so you have time to count responses and place the order. For example, if the supplier needs three days and you want to order on Tuesday, ask for confirmations by the previous Friday. Explain the timeline in your initial message so people understand why you need their answer sooner. Always build in a small buffer in case the supplier or delivery is delayed. Never wait until the last possible moment to order.

If people pay or commit once for all sessions, get one confirmation covering the whole series and order materials for everyone at the start. If each session is independent, confirm attendance before each one and order materials accordingly. For a series where people might drop out, consider asking for session-by-session confirmation if materials are expensive, but this creates more coordination work. Make clear at the outset whether signing up means committing to all sessions or just one at a time.
