How to handle Stripe subscriptions based on Currency?

I'm using the Stripe payment gateway for my SAAS app.

I have created a Product and multiple Plans are linked to it. Plans price is in USD.

I have created a new customer. Then I'm trying to subscribe to a Plan, but I'm getting the below error 

You cannot combine currencies on a single customer. This customer has had a subscription, coupon, or invoice item with currency inr

I have seen their documentation, it is not allowing me to change the Currency of the customer.

Is there anyway I can convert USD to the currency of the customer before subscribing?

My recommendation would be to, prior to attaching the subscription, retrieve the customer object for which you'd like to have a subscription attached, determine the currency of the customer, and create a new plan (in the currency) if necessary. To do this though, you'd probably want to use a currency conversion API from a third-party, as Stripe does not support that.

Example in Python:

plan_id = ...  # This would have been retrieved from your form, most likely  (eg. 'basic-plan')

usd_plan = stripe.Plan.retrieve(plan_id)

cus = stripe.Customer.retrieve()

if cus.currency is not 'usd':  # if the currency of the customer is not "usd"

  # create a new plan id for currency (eg. 'basic-plan-cad')
  plan_id = plan_id + '-' + cus.currency  # check if there is a 
  
  # use a 3rd party to get the currency
  amount_in_currency = amount * <API_CONVERSION_RATE>

  # check that the plan doesn't already exist and create it otherwise
  try:
    stripe.Plan.create(
      amount=amount_in_currency,
      interval=usd_plan.interval,
      product={
        "name": usd_plan.product
      },
      currency=cus.currency,
      id=plan_id
    )
  except Exception as e:  # this may fail if the plan already exists
    break

# create the subscription
sub = stripe.Subscription.create(
  customer="cus_xxx",
  items=[
    {
      "plan": plan_id,  # this will either be the `basic-plan` or `basic-plan-{currency}
    },
  ]
)
