With custom payment types added in POS, along with cash being accepted as a payment method, there does not seem to be analytics/a report to see each staff members breakdown of payment accepted, for example two staff members on a shift, how much cash did each take using their codes. Thank you for your feedback.
There are a number of reports in Shopify designed for Retail POS sales. Unfortunately, none of them show the payment method(s) used by the customer.
Our Report Toaster app can help. We have a number of pre-built Retail reports which can be customized as you need. Please feel free to take a look and reach out to support if you need help customizing.
