A successful eBay business has four numbers that actually matter: profit, profit margin, average sale price, and sell-through rate.
Everything else (listing count, "busy", 90-day revenue on the app) is a proxy. If you cannot name those four, you do not have a plan. You have a goal with no map.
Put them in the planner first
Matt plans monthly, not yearly. Hit enough months and the year happens.
His long-running monthly profit target: $4,000. He has hit that for a couple of years. He still leaves it there.
The other three inputs he used in the walkthrough:
- Margin 40%. What is left after fees, postage, cost of goods, and the boring expenses. Industry-standard for a part-time, single-car-garage store. If you do not know yours, that is the gap Flippedit fills.
- ASP $50. Below that, Australia Post and eBay fees eat the day. He shows later in the video what happens if you miss it.
- Sell-through 90% over 90 days. Under 30 days on an item is fast. 30–60 is acceptable. Past that, the store size starts running away from the sales.
The right-hand side of the planner is the job: how many items, how much to list per day, how much revenue you need. Change one input on the left and the job changes.
