We are a bit different, but, we print on demand. We also do custom work utilizing a GTX Pro DTG machine. I havent a good answer for you honestly. Square is a terrible platform for businesses like us. Printavo integrates but the cost of square and printavo is ridiculous. Most other 3rd part design tools want your customer to pay through them.
From my investigations, you'll have to shopify and third party it. Or fulfillment like t-springs. I think they use INKSOFT.
However, we own two brick and mortar stores, and we utilize square for mainly inventory and walk in sales. I do have a category and named it custom prints since we have three methods of fulfilling orders. We DTG, DTF, and Heat Transfer. We don't have the facilities to screen print or I would.
Invoices are the worst thing about square. Takes two hours to get a 500 item invoice or estimate together. Would be better if they had an import from excel like they do purchase orders. If I had 500 line items in an invoice, Say 10 different colors of a hoodie, and all those colors had 7 variations (Sizes) thats 70 line items. Lets add tshirts and long sleeves and maybe a few crew necks. Crew necks get discounts and hoodies get a different discount, I have to manually into each line item and select the correct discount. So time consuming. Anyways, I got off the topic and started to vent.
There are great third party integrations out there like printavo, but if I am using sqaure as an base for inventory control and they are accepting the payment, there is no way to deplete.
Also, lets say I want to fulfil an artist or designers art on a shirt. He comes to us and asks if we can print and fulfil. We can, here is what we do. I overlay the art on a png (Say Crew neck) like a mock up. Customer gives me t shirts hoodies and crew necks to place his art on. I make a separate item and use options. Colors, style, size. and then create the item. Problem is that's about 150 variations. I give him the link, he shares it, his customers click it which re directs to our online squares store, they pay, and then we deliver.
Would be nice for square to give us an option to for a customer to choose a design and drag it over another picture(Design on a crewneck) and /or give us a design tool for customers to use. That would make life so much easier.
The way it is now, it is too time consuming. 300 a month for Printavo, but then you have to manually keep track of your inventory. Or use sanmar's integration and just give a 7-10 day lead time.
If you come up with a solution, I would lave to hear it as well.
