In late July 2026, merchants in Brazil and Paraguay were advised to monitor how interest rates on card-machine installment transactions are calculated. These rates are variable, determined by sales history, the number of installments, and specific contractual terms with processors.

By August 2026, the focus shifted to a comparison of specific payment providers in Brazil. Companies such as Ton and PagBank were noted for offering competitive promotional rates, starting at approximately 0.57% for debit and single-installment credit transactions. Other providers, including Mercado Pago, InfinitePay, and SumUp, remain options depending on business needs such as revenue volume and settlement timelines.
