A more advantageous approach would be to provide various subscription tiers based on the volume of orders. For instance, a monthly fee of $15 or a yearly free of $150 could be established, with an fixed additional charge of $0.5 depending on the number of transaction per month. This subscription model would be ideal for small e-commerce businesses offering between 5 to 15 customizable products. For those wishing to include more products, an additional fee of $1 per customizable product per month could be applied. Regrettably, I was very enthusiastic about implementing your solution in my new Shopify store; however, I ultimately opted for your competitor, who provides a more advantageous subscription plan with equivalent services. Their offer is $19 per month for 100 transactions, with an additional charge of $0.60 for each extra order. I hope you will introduce a comparable option in the near future. Thank you.
