Common questions
Are there specific interchange rates for B2B card transactions in this MCC?
Yes, B2B card transactions, especially with commercial or corporate cards, often qualify for lower interchange rates compared to consumer cards.
Merchants should ensure their payment processor supports Level 2/3 data capture, which helps in qualifying for these optimised rates by providing additional transaction information to the card schemes.
What are common reasons for chargebacks in testing laboratories?
Chargebacks in this sector are often related to 'services not as described' or 'cancelled services'. This could include disputes over the accuracy or reliability of test results, a lack of communication regarding delays, or reports not being delivered within agreed timescales.
Clear service agreements and robust communication with clients are paramount.
How can 3D Secure be applied effectively for B2B transactions in this MCC?
While B2B transactions might seem less risky for fraud, 3D Secure (3DS) can still be beneficial for liability shift. However, friction can be an issue.
Cardflo recommends implementing a 'smart 3DS' strategy, selectively applying 3DS based on transaction value, historical customer behaviour, and other fraud signals, rather than on every transaction.
