Calculating Tax for a specific product type

We are building an app where we provide an optional service to the consumer.

  • This service is paid for by the consumer at checkout.
  • This service is built as a product with variable pricing.
  • This service is taxable is some jurisdictions.

We have the correct tax code(s) for our specific service/product.

Question(s)

  • How can we use Shopify Tax to calculate our service product correctly and apply the tax amount to the total tax paid by the consumer?
  • Would the Merchant remit those taxes or would we as the service provider be able to collect the Tax Paid and remit on behalf of the Merchant?
  • Can we apply the same logic with a Merchant who is using AvaTax vs Shopify Tax?
