Manually repricing costs you twice: the time you spend doing it, and the sales that slip away while your prices sit stale. See both numbers.
Manual repricing labor cost
$757.75/mo
7.0 hours/week of your own time spent opening listings and typing new prices in — not selling, not sourcing.
Your price-exposure window: 24.0 hr — the average stretch between your checks where a competitor can undercut you and you won't know until you look again.
Every price-sensitive sale that happens inside that window goes to whoever is cheapest at that moment — not necessarily you, even if you were the lowest an hour ago.
Undercut re-checks and reprices automatically as often as every 15 minutes, shrinking your exposure window by 99% — with a hard floor so faster never means cheaper than you can afford.
Sellers who reprice manually almost always underestimate what it's costing them, because the labor time is the only part that's visible. You can feel the minutes you spend opening listings and retyping prices. You can't feel the sale that went to a competitor at 9:40pm because your last price check was at 8am.
That second cost compounds with volume: the more listings you run and the more competitive the category, the wider your real exposure window gets relative to how often you can realistically check it by hand. It's the same problem Undercut exists to close — competitor tracking and repricing on a fixed automated cadence, with a hard price floor so speed never costs you margin.
Undercut watches every listing and reprices on a fixed schedule — as fast as every 15 minutes — floor-protected the whole time. Start free, no card.

What is "repricing lag"?
The gap between when a competitor changes their price and when you notice and react to it. If you check listings once a day, your lag can be up to 24 hours — during which any price-sensitive buyer goes to whoever is cheapest right now, not whoever was cheapest at your last check.
Is manual repricing actually that expensive?
It has two costs, and most sellers only feel one of them. The visible one is your time — minutes per listing, per check, adding up over a week. The invisible one is the sales lost during your exposure window, which never shows up as a line item because you never see the sale you didn't get.
How often do I need to reprice to stay competitive?
It depends on the category. Commodity items in high-competition categories can see price changes many times a day; slower categories move less. The safer default is to shrink the window as much as you reasonably can — checking once a day leaves a much wider opening than checking hourly.
Does faster repricing mean racing to the bottom?
Only without a floor. Undercut reprices fast but never below the per-item minimum you set — speed closes the exposure window, the floor protects the margin. Neither works without the other.
