Are Firestore updates charged the same cost as writes?

According to Firestore documentation, it is possible to update a single field without updating the entire document:

def update_create_if_missing():
db = firestore.Client()
city_ref = db.collection(u'cities').document(u'BJ')

city_ref.update({
    u'capital': True
}, firestore.CreateIfMissingOption(True))

Are Firestore updates charged as writes?

Is there an option such as "update if different" instead of the current one which is updating if missing?

I have built quite a heavy price comparison application with more than 1 million products (each product is a document in Firestore) updated on a daily basis. It would be quite expensive if I had to pay 1.000.000 writes per day on top of the Firestore reads.

Is there any alternative I could explore?

To add to Doug's answer, Firestore considers document creations, updates and even deletes as billable write events. Read up more on their official documentation here.

Firestore document updates are not different than writes. Any operation that changes a document is considered a write.
