Any suggestions for a more appropriate platform?

I run a travel-based small business (Japan Craft Tours), and Shopify makes it shockingly difficult to send balance invoices to customers who’ve already paid a deposit.

I spent 3 hours trying to:

  • Create draft orders for final payments (I only need 7)
  • Copy checkout links without triggering emails
  • Send invoices via Flodesk because Shopify Email won’t let me send to a single customer
  • Build workaround pages just to hide long, ugly invoice links

All because Shopify:

  • Doesn’t allow manual access to invoice URLs
  • Doesn’t let us email individual customers
  • Doesn’t support basic segmentation unless you’re on Plus

I love what I’ve built, but Shopify is clearly optimized for physical products — not real-world, multi-step service models like tours, coaching, classes, etc.

Please fix this.
