ClearSale

ClearSale is a company that provides fraud-prevention and chargeback-protection services to e-commerce merchants. Founded in Brazil in 2001 and now operating internationally, it screens online transactions to identify and stop fraudulent orders while letting legitimate ones through. Its defining approach is to combine automated machine-learning analysis with human review: the system scores incoming orders against historical data and flags suspicious ones, but rather than automatically declining everything that looks risky, ClearSale routes flagged orders to human fraud analysts for a closer look. The idea behind this hybrid model is that fully automated systems reject many genuine customers along with the fraudsters, and human review recovers a large share of those good orders that an algorithm alone would have turned away. ClearSale became part of Experian, the credit and data services group.

For an online merchant, ClearSale sits in the checkout flow as a decision layer. When a customer places an order, the order is assessed and a decision — approve, decline, or investigate — is returned, often before the purchase completes, so the merchant can fulfill good orders and stop bad ones. The service integrates with common e-commerce platforms and shopping carts through plugins and an API. A central part of its offer is a chargeback guarantee: on transactions ClearSale approves, if an approved order later turns out to be fraudulent and results in a chargeback, ClearSale covers the cost. That shifts a portion of fraud risk from the merchant to the provider, which is a meaningful promise in a category where merchants usually bear chargeback losses themselves.

ClearSale operates in the broader category of e-commerce fraud prevention, where the core tension is between blocking fraud and approving genuine customers. Tighten the filters too much and you decline real buyers, losing revenue and annoying customers (so-called false declines); loosen them too much and fraud and chargebacks rise. ClearSale's pitch is built around resolving that tension: its hybrid of machine scoring plus human analyst review is meant to approve more legitimate orders than a purely automated system would, while still catching fraud. The chargeback guarantee aligns the provider's incentives with the merchant's, since ClearSale absorbs the cost of fraud on orders it wrongly approved. This is a factual description of the company's model, not an endorsement or a claim about specific performance figures, which vary by merchant and are not stated here.

Within the merchant's stack, ClearSale is one option among several fraud-prevention and chargeback-protection providers, and the right choice depends on a business's order volume, risk profile, margins, and tolerance for false declines versus fraud losses. The practical reasons a merchant considers a service like this are concrete: reducing chargeback costs and the penalties that come with high chargeback rates, cutting the manual review burden on its own team, recovering revenue lost to over-aggressive auto-declines, and transferring some fraud risk via a guarantee. The trade-offs are the cost of the service and the dependence on an external decision layer in the checkout flow. As with any vendor, the sensible approach is to evaluate fit against the business's own numbers rather than assume any single provider is best for every merchant.

Using a service like ClearSale well means treating it as one part of a deliberate fraud strategy rather than a set-and-forget switch. Be clear about what you are optimizing: a merchant losing good customers to false declines has a different problem from one bleeding revenue to fraud and chargebacks, and the configuration should reflect which matters more for your margins and volume. Integrate the decision layer cleanly into checkout so it adds protection without adding friction for genuine buyers, and monitor its performance — approval rates, declines, chargebacks, and the customer experience — rather than assuming the system is tuned correctly out of the box. Where a chargeback guarantee is offered, understand exactly what it covers and what it excludes, since the value of that promise depends on its terms.

The failure modes are the same ones the category exists to address, plus a few of management. Over-blocking still loses real customers if the system is tuned too aggressively; under-blocking still lets fraud through; and a merchant that adopts a tool but never reviews its outcomes can drift into either ditch without noticing. Relying on the guarantee without reading its terms can leave gaps uncovered. The discipline is to choose a provider that fits your specific risk and volume, configure it to your real priorities, integrate it smoothly, and keep watching the numbers — approvals, declines, chargebacks, and customer friction together — so the service genuinely reduces fraud and false declines rather than quietly trading one problem for another. No fabricated performance figures are claimed here; evaluate any provider against your own data.
