The blank page is the hard part, so here is a week with the decisions already made. None of this needs a full day.
Day one — open the store
Identity check, bank details, and a store name you will still want in a year. The check is the gate on taking money, so starting it first means the rest of the week is not waiting on it.
Day two — three listings, not thirty
Three things you know well, photographed by a window, measured, described plainly. Three good listings teach you more than thirty rushed ones, because you will actually read the questions people ask about them.
Day three — set your delivery once
Build one delivery profile and point everything at it. Decide what you post, where you post it, and whether you offer collection. This is the part people leave until an order arrives, and then do badly in a hurry.
Day four — set your dispatch window and look at your calendar
48 hours is the default. If that is not true of your week, change it now rather than missing it later.
Day five — one small show
Twenty minutes, five items, no audience to speak of. The first show is not for selling; it is for finding out that the camera is fine, your light is not, and that you talk faster than you think.
Day six — rest, and let the listings sit
Buy-now listings run for 30 days. Nothing needs doing.
Day seven — read the numbers
Sell-through first: of what you put up, what sold. Then the questions people asked, which are a list of what your descriptions left out.
What a good first week looks like
One or two sales, a short show that did not fall over, and three things you now know to do differently. Not a profit.
Questions people ask
Should I wait until I have a lot of stock?
No. Five buy-now listings is the starter limit anyway, so the first week is sized for a small shelf by design.
What if nothing sells?
Then week one did its job cheaply. Sell-through on three items tells you about pricing or photographs, and both are fixable.
Do I need to go live at all?
No. Plenty of stores sell only through listings. The show is worth trying once so the choice is informed.
