Am I Overcomplicating Loyalty Points?

I am the marketing department - we're looking to set up a receipt upload system where people can earn points by DMing our Instagram, their receipts being verified, and points being awarded.

So far, me and GPT have spat out this solution:
1. Customer sends receipt to DM
2. I verify info and upload into a Sheet filled w/customer points data
3. Zapier scans this and sends it to Klaviyo
4. Klaviyo sends confirmation emails, alongside regular emails for pop-up notices and deals, etc

We're a cultivation brand, no dispensary P.O.S. Am I overcomplicating this setup? It's my first time doing this as we're a small brand, and other brands' loyalty points are either vertically integrated because they own the dispensary or seem to be custom solutions.
