House Accounts for POS

Lilya: House Accounts for POS lets regular customers buy on account in Shopify POS and pay later. You give a customer a credit limit; staff sell on account with the Charge to account tile. The sale becomes an unpaid Shopify order with Net 30 payment terms (or the customer's own terms) and an optional PO number, and it is refused if it would take the customer over their limit.

The app shows each customer's balance, credit limit, and overdue amount in POS and in the admin, ages open orders (0–30, 31–60, 61–90, and over 90 days), and prints or emails customer statements.

Shopify stays the record of every sale and payment. The balance is always the sum of the customer's unpaid orders in Shopify: when you collect a payment on an order, the balance goes down. The app never records payments itself.
