Sold Works gives your sold originals a gallery of their own. Each original sits in your store with a stock of 1. When a buyer pays and the stock reaches 0, the work moves into the gallery by itself, newest first, with a small red dot and a line like "48 works collected". You don't move it to a "Sold" category or rename it.
Most artists leave sold pieces in the shop under "Out of stock", or delete them. This keeps the shop for what's for sale and the record of what's gone.
Works show on a soft mat so paintings of any shape sit whole, or in a masonry layout with their own proportions. Sold works never show a price. You can change the heading, the line under it and the count wording, choose how many works show and pick a font. While nothing is sold, the gallery stays hidden on your site.
The free plan shows up to 12 sold works with the count and a small credit link. Premium shows up to 60, can keep to one category (only Originals, not prints), adds an "Available now" row with prices and a "Commission a piece like this" button, lets you write "Collected" or "In a private collection" instead of "Sold", adds linen and charcoal themes, and removes the credit link.
