Add it once. Create texts, images and videos yourself or have them made. Publish to every channel and see what sells.
Every product starts as one record: photo, name, brand, EAN, price. You can add it by phone photo, upload a CSV, pull it from a connected marketplace or from Afterbuy. From here everything else is built on that record, so nothing is entered twice.
Free tier, no card. The first listing is free, so is the second.
