What this check is
A £120 order reads very differently as three payments of £40. Splitting the price into installments lowers the perceived barrier at the point of decision, and the wallets that offer it also shorten checkout.
How to implement it
Enable the installment provider for the markets where it is available, turn on the price-breakdown message on the product page and in the cart, and confirm the widget uses the store currency. Test both the widget and the actual payment so the promise and the checkout agree.
How to verify it
Open a product above the provider’s minimum in each supported market and confirm the installment amount recalculates with currency and quantity, then complete a test order choosing the installment method.
