Guide
If you sell on eBay around a full-time job, your biggest disadvantage is not price — it is attention. Full-time competitors adjust prices throughout the day while you are at work, asleep, or with family, and the listing sitting one dollar too high quietly loses the sale. You do not need to babysit prices to compete, though. Automated repricing with a hard floor handles the adjusting for you: it beats the lowest competitor in the moments you cannot, and it never drops below the minimum you set. This guide shows how a part-time seller with under 100 listings gets most of the upside on the free or Starter plan.
A part-time seller and a full-time seller can list the identical item at the identical price. The difference shows up over the next eight hours: when a competitor drops their price at 11am, the full-timer responds by noon and the part-timer responds at 6pm — after losing a day of being the cheapest comparable listing. Multiply that across a week and a modest inventory and it is a real number of missed sales. Repricing software closes that gap by reacting on your behalf around the clock. You are effectively present in the market even when you are not at your screen, and a hard floor guarantees nothing ever sells below the price you would have accepted yourself.
Suppose you carry 25 active listings averaging a $12 profit per sale, and being consistently first on price would win you just two extra sales per week. That is roughly $24 a week, or about $100 a month, in recovered profit — from sales you were already losing to slow manual repricing. The free plan covers exactly that 25-listing scenario at no cost, so the recovered profit is pure upside. If you grow to 100 listings, the Starter plan is $29/mo; at the same $12 average profit you only need about three extra sales in the entire month to cover it, and active repricing typically wins far more than that. The point is that the math favors automation well before you go full-time.
The whole appeal for a busy seller is that the setup is front-loaded and the running is hands-off. You connect your eBay account, import your listings, and set a hard floor on each one — the lowest price that still clears your cost, shipping, eBay's fee, and the margin you want. From then on the repricer beats the lowest comparable competitor automatically and stops at your floor every time. There is nothing to check daily. You can revisit floors when your costs change or when you add inventory, but the day-to-day price chasing — the part that does not fit around a job — is simply gone.
Stay on the free plan while you are at or under 25 active listings; it covers the core benefit at no cost and is the right way to learn the floor-first workflow. Move to Starter when your active count climbs past 25 and the extra sales clearly cover $29/mo — which, as the example above shows, happens quickly. You generally do not need Pro's 15-minute cycle or AI aggressiveness tuning as a part-timer; those matter most for high-volume or fast-moving inventories. Upgrade for listing capacity first, speed second, and only when the inventory actually justifies it.

Do I need to watch prices at all once it's set up?
No. After you set a hard floor on each listing, repricing runs on its own — it beats the lowest comparable competitor and stops at your floor automatically. You only revisit floors when your costs change or you add new inventory.
Is the free plan really enough for a part-time seller?
For many, yes. The free plan covers 25 active listings repriced multiple times daily, which captures the core benefit of staying competitive while you're at work. You upgrade only when your listing count grows past 25.
Will hands-off repricing accidentally sell my items too cheap?
No. The hard floor is the safeguard — Undercut never prices any listing below the floor you set, so automation can only ever win sales at or above your minimum acceptable price. It never races to the bottom.
I have a day job — how long does setup take?
Setup is a one-time job: connect eBay, import listings, and set a floor on each. For a small inventory that's a short evening's work, and there's nothing to maintain daily afterward. The 14-day trial needs no card to start.
When should I move from free to Starter?
Upgrade when your active listings pass 25 or when the extra sales clearly cover the $29/mo Starter cost. At a typical $12 profit per sale, roughly three extra sales a month covers it, and active repricing usually wins more than that.
