With the arrival of Black Friday, companies of all sizes need to prepare for the increase in transaction volume and more demanding consumer behavior. To assist in this preparation, iugu has compiled practical guidelines that contribute to a more secure, efficient operation with a higher conversion rate.
Among the key recommendations is the importance of notifying the Payment Service Provider (PSP), e-commerce platform, and suppliers in advance about the expected increase in sales volume, and whether this volume will exceed traditional operation levels. This communication prevents transaction peaks from being misinterpreted as fraud attempts and resulting in unwarranted blockages. “A common mistake is failing to notify the acquirer about the volume increase. When the system identifies an unexpected peak, it may interpret it as suspicious behavior and block operations. A simple prior communication already minimizes this,”, explains Fabricio Divitiis, Commercial Superintendent at iugu.
Another essential point is ensuring agile technical support, with teams prepared to respond quickly in case of any unforeseen events. During high-demand periods, minutes of downtime can lead to significant losses in sales and reputation. It is also important to review payment method configurations, checking whether installment rules, interest rates, and promotions are up to date, and to test the entire customer journey—from checkout to confirmation—to identify failures and/or opportunities to increase revenue before the access peak.
Personalizing the purchasing journey also makes a difference. Having a proprietary domain checkout and a secure environment builds trust and reduces exposure to fraud, increasing the conversion rate. Furthermore, it is recommended to analyze and activate all payment methods relevant to your business, such as credit cards, bank slips, Pix, and digital wallets, to cater to different consumer profiles and enhance closing opportunities.
Still focused on boosting sales, Black Friday can be an opportunity to secure continuous revenue. Subscription campaigns with strategic discounts help retain customers and keep cash flow circulating throughout the year. For example, offers like “First 3 months with 50% OFF” can aid in revenue predictability even after the sales peak.
Attention to documentation and organization with operational partners is also crucial. Ensuring that registrations and contracts are up to date prevents delays in payment releases. The use of automated commission transfer solutions, such as payment splits, allows for the distribution of amounts among different operational areas, such as influencers, affiliates, or business partners, ensuring speed and accuracy.
Finally, it is essential to reinforce internal security: reviewing administrative access, resetting passwords, and adopting two-factor authentication help protect data and transactions. And, of course, keeping Pix enabled and tested ensures a fast and secure payment method for the event.
“Planning, testing, and security are the keywords for Black Friday. The more prepared the financial technology is, the greater the potential for sales and customer retention post-event,” concludes Divitiis.
