An Alpha Repricer Alternative for OnBuy

Alpha Repricer markets itself on Amazon repricing speed, and for sellers fighting over a fast-moving Amazon Buy Box that is a reasonable thing to optimise for.

OnBuy is a smaller and slower-moving marketplace, and the sellers who do well on it tend not to be the ones who react fastest - they are the ones who never accidentally sell below cost while reacting. That shifts what a repricer needs to get right.

Margin control first

Re-Pricer is built around not losing money:

• Hard floors and ceilings per SKU. Your price moves inside a band you set, and never outside it.
• Fees in the calculation. OnBuy's category commission and VAT are part of the floor, so the minimum is a genuine profit minimum.
• Delivered price comparison. Item plus shipping, because a cheaper item with dearer delivery is not actually cheaper.
• Out-of-stock repricing. Recover margin automatically when a competitor's stock runs out.
• Competitor visibility. See who you are up against on a listing and where your delivered price sits against theirs.

Prices are checked as often as every 10 minutes on the 10,000-listing plan and above, hourly on the entry plan. That is fast enough for OnBuy, and the honest reason it is not faster is that the marketplace does not require it.

The practical difference

If you sell on Amazon, keep an Amazon repricer. If you sell on OnBuy, you need something connected to OnBuy. The two are not really competing for the same slot.

The quickest way to settle it is to run both for a week. Connect your OnBuy API key, import your catalogue, set a floor and a ceiling on your top twenty listings, and watch what happens to your position over a few trading days. Re-Pricer starts at £34.95/month with a 7-day free trial, and setup takes under a minute.
