We are a Shopify store selling products that are weighed. A customer order 2 pounds of an item at say 2.99 per pound, when we go to pick the item it might be a little under or over on weight which affects the actual price. Up to this point we have been using auto capture with Shopify payments and has been fine. The question is is there a way to 1) authorize the credit card use for a larger amount to allow for items that go over weight 2) when item has been picked we edit the order to show the actual amount of weight and price 3) we then adjust the order total to reflect this.
I suppose this would also be needed if an item were needed to be substituted.
