I've gotten a lot of questions about how I invoice for tee parties. Now, let me preface this: you are NOT wrong if you prefer to invoice differently. This is what what works best for ME.
I have invoiced several different ways over the 5 years that I've been hosting tee parties.
• In the beginning: I posted the shirts to FB, people commented on the photo of the shirt they wanted with their size, shirt color, shirt style and email address. I would type out all of the orders on a word doc and then email an invoice via shopify. This would take HOURS
• Change 2: I posted the shirts to FB, people commented on the photo of the shirt they wanted with their size, shirt color, shirt style and email address. I would type out all of the orders in an excel doc and then email an invoice via shopify. This took less time because of the ability to filter and group the orders, but it still took a long time having to chase down email addresses & then resending invoices if they went to the customers spam folder, etc
• Change 3: I posted the shirts to FB, people commented on the photo of the shirt they wanted with their size, shirt color & shirt style. I would type out all of the orders in an excel doc and then create a collection in Shopify (I would name it whatever the party date was), then each order was entered in Shopify as a product. This was much more efficient. Customers knew exactly where they needed to go to find their order and pay their invoice, there was no chasing down email addresses or searching through spam.
• Change 4: I used the Infinity Options app in Shopify and posted all of our shirts there. I would unlock the site on Thursday and then relock it on Friday. Customers were able to select their shirt size, color, style, etc and check out immediately. Our sales plummeted FAST. Because customers were able to check out on their own, they were no longer engaging on our FB group, so our organic reach dropped quick... and if people don't SEE reminders of upcoming parties and sales then they forget, which translates to not ordering.
• Change 5: we went back to Change 3. It took about 3 months for our reach to get back to where it was before we made the change to all orders being placed directly through shopify.
I made a video that walks through how I post invoices for tee parties & our VIP group on our shopify website. It is very important that you remember you HAVE to make code changes to your website so the product details will display on your printed orders. If you don't make that change, then when you print the order form only the name of the customer will be displayed on the order form. I paid a developer to do it because I didn't want to mess with it. It took him about 30 minutes to do, cost me about $100 and was WELL WORTH IT!
