Assisted Checkout vs Autobuy Bots

Why speed matters on new listings

An underpriced listing can only be bought once, and the first completed checkout wins. Most of the time between the listing going live and your payment is yours: noticing the alert, judging the photos, filling in details. Measure it before you pick a tool:

• For your next 10 alerts, note when each arrived, when you reached payment, and whether the item was already gone
• Note the slowest step: noticing, judging or filling in checkout

If judging is slowest, tighter buying rules help more than software. If checkout is slowest, that is the step assisted checkout removes. Getting alerts at all: new listing alerts for Vinted, OLX and Allegro Lokalnie.

What an autobuy bot does

An autobuy bot watches for listings that match a rule and completes the purchase without waiting for you. To do that it needs a way to act as you (a logged-in session or your login details) and a payment method it can use on its own.

What it does well is speed: it never sleeps or hesitates. What it gives up is the check between "matches" and "paid". Anything fitting your rule's wording gets bought: a wrong size in the right category, damage visible only in the fifth photo, a listing titled "box only".

What assisted checkout does

Assisted checkout splits the job at the payment step: software does the mechanical part in your own session, you judge and pay.

Decision rule: if a tool can finish an order while your phone is locked, treat it as an autobuy bot, whatever the vendor calls it.

Who controls payment

With a bot, your rule is the last check before money leaves. With assisted checkout, you are.

Keeping the pay button costs you items that go while you can't respond; a bot costs you unwanted items. Don't count on sending a bad private buy back: OLX's Terms say consumer-protection rules do not apply between consumers.

Passwords, cards and session security

A tool that buys has to act as you. One running on a vendor's servers needs a way to log in as you, and a bot usually needs a payment method too; a breach there exposes both. A tool in your own browser session only uses the session you opened. Before you connect a buying tool, get written answers:

• Do you ask for my marketplace password, and where is it stored?
• Do you store my card, or do I pay only in the marketplace's own checkout?
• Can the tool act while my browser is closed?
• How do I cut off its access in one step?

What marketplace terms say: no exemption for in-session tools

Control and security are reasons to prefer assisted checkout, not a permission. These clauses, checked 13 September 2026, apply whoever presses pay:

eBay's ban covers "any automated means", so pressing pay yourself doesn't replace eBay's permission. We couldn't read Allegro's current terms, so we make no claim about Allegro or Allegro Lokalnie.

Vinted's updated Terms take effect on 5 October 2026 in Germany and France and on 8 October 2026 in the UK and Poland. Value Added Resource (September 2026) reports the UK bot rules unchanged; reread the live terms after 8 October. Vinted clause by clause: are Vinted bots allowed. All marketplaces: marketplace automation rules.

Decision rule: if a vendor says its tool is fine "because you press pay", ask which clause of the marketplace's terms says so.

Rules and limits that stop bad buys

With either approach the rule is the first filter; with a bot it is the only one. Write limits that fail closed:

• Maximum as a total: listing price plus buyer fee plus delivery to you
• Minimum profit after the fees where you will resell
• Exact sizes, models or storage, not just a category
• Required photos: labels, flaws, a phone screen switched on
• A daily spend cap, and a pause after any bad buy until you know why the rule let it through

Setting each number from your own log: how to set buying rules as a reseller. In reva, rules drive alerts; you confirm and pay, and reva acts only where the marketplace allows.

Screenshots and audit trails

When software acts in your account, keep a record: to check the rule behaved as written, to settle disputes about what a listing showed, and to explain your activity if a marketplace asks. Per purchase, keep:

• The listing link and the listing as the tool saw it: title, price, photos, condition
• The rule that matched, and the time
• The checkout screen before payment, showing the total
• The order confirmation
• Anything the tool did besides checkout: messages, offers, favourites

That last line matters on Vinted, whose external-tools clause names "adding Items to favourite". Decision rule: if a tool can't show you what it did, don't let it act in your account.

Which approach fits which reseller

• You buy on eBay or Grailed: no automated ordering without the marketplace's permission. Use alerts and buy by hand.
• You can respond within minutes most of the day: assisted checkout where the marketplace allows it, otherwise alerts and manual checkout.
• You can't check your phone for hours: a bot tempts, but it spends unreviewed under the same terms. Accept missed deals, or source when you can respond.
• You buy few, expensive items (phones, designer pieces): keep the pay step yours; one wrong buy costs more than one missed deal.
• You're new to a category: alerts only, until your log shows the rule rarely lets a bad item through.
