What MCC 7379 covers
Merchant Category Code 7379 is the ISO 18245 identifier used by the card networks for computer maintenance, repair & services (nec). Acquirers, issuers and regulators use this code to set interchange, scheme fees, fraud rules and reporting categories for every transaction your business processes.
IT support, computer repair and managed services. Choosing the right MCC is critical: an incorrect code can lead to higher interchange, surcharges, or, in regulated categories, declined transactions and account holds.
This MCC covers computer maintenance, repair, and miscellaneous computer services not elsewhere classified, including IT support, computer repair shops, and managed IT services providers. Transaction sizes vary greatly, from small, one-off repair fees (£50-£200) to larger, recurring monthly retainers for managed services (£500+).
Frequency for repair services is infrequent, while managed services offer predictable recurring revenue.
Chargebacks are generally low but can occur due to perceived poor service, unresolved technical issues, or billing disputes for recurring services. 'Services not rendered' or 'services not as described' are common reasons.
Cardflo's adaptable payment gateway supports both one-off and recurring payment models, coupled with robust dispute management tools, making it well-suited for the varied transaction patterns and occasional service-related disputes in this MCC.

Common questions
What specific documentation is crucial when defending a 'services not as described' chargeback for computer repair?
For 'services not as described' chargebacks in computer repair, critical documentation includes signed work orders detailing the requested and performed repairs, diagnostic reports, before-and-after photos or video (if applicable), itemised invoices, and proof of customer pick-up or delivery.
Any communication with the customer acknowledging satisfaction or problem resolution is also highly valuable.
How can merchants in MCC 7379 ensure PCI DSS compliance for on-site payment collection?
For on-site payment collection, merchants should use PCI-compliant point-of-sale (POS) terminals that encrypt card data at the point of interaction (P2PE devices) or secure mobile payment applications.
Using a Cardflo-integrated terminal or virtual terminal ensures that sensitive card data never touches the merchant's uncertified systems, significantly reducing the scope and burden of PCI DSS compliance.
Are there specific interchange rates for small-ticket repair services in this MCC?
Small-ticket repair services might benefit from lower interchange rates on certain debit card transactions, especially within the EU due to regulated interchange caps (0. 2% for debit, 0.
3% for credit consumer cards). For non-regulated regions, specific small-ticket interchange categories might exist depending on the scheme and card type, which Cardflo's intelligent routing aims to leverage for cost optimisation.
