Ive used Printhouse.io for 2 years before they listed in the shopify app store. I love them. once its all set up and uploaded images are connected to store products (this is time consuming and requires adding extra 1.5" borders for each image file for stretched canvas), its virtually no touch ordering unless you want to do manual ordering. Ive talked with their customer service several times and each time they were quick to reply, knowledgeable and professional. The products are Excellent quality. the True Glicee canvas prints are worth it for my visual art prints. Decent pricing. The white label branding choices are great. Shipping is included in pricing which is a bonus, Printed in the USA another bonus and their ship times are fair. I definitely recommend them if you want white label high quality canvas prints for your art. This is all they do so they are good at it, unlike cheap do it all print stores selling tshirts and mugs using cheap non archival inks and cheap canvas. the only complaint is the time to set up all your file in the proper sizing.
