AOP+ is a print-on-demand company that integrates with Shopify, allowing customers to order products that are then sent to AOP+ for printing and fulfilment. With print-on-demand, customers only pay for what they sell, eliminating the risk of buying a large inventory. AOP+ does not have any minimum requirements and is one of the few print-on-demand services that prints everything in-house, rather than outsourcing the printing.
