What MCC 8911 covers
Merchant Category Code 8911 is the ISO 18245 identifier used by the card networks for architectural, engineering & surveying services. Acquirers, issuers and regulators use this code to set interchange, scheme fees, fraud rules and reporting categories for every transaction your business processes.
Architects, engineers and surveyors. Choosing the right MCC is critical: an incorrect code can lead to higher interchange, surcharges, or, in regulated categories, declined transactions and account holds.
Merchants in MCC 8911 encompass architectural, engineering, and surveying services, predominantly B2B or B2G professional service providers. Ticket sizes vary widely, from smaller consulting fees to substantial project-based payments, with billing often milestone-driven rather than high-frequency.
These services typically involve complex contracts and deliverables.
Chargebacks are infrequent but can occur due to disputes over service quality, project delays, or perceived non-delivery of agreed-upon designs or reports. Scheme rules generally treat these as standard professional service transactions, without specific high-risk monitoring programmes.
Most payments are card-not-present.
Cardflo supports these professional services organisations with robust B2B payment acceptance, including features for partial payments or staged billing, crucial for project-based work, and flexible MID structures to accommodate various service lines.
Configure acceptance to accommodate the project-based, often high-value nature of architectural, engineering, and surveying services, focusing on multi-acquirer routing to optimise for commercial card interchange rates. Given stable client relationships, prioritise secure CNP processing with 3DS2 for substantial upfront fees or milestone payments.
The low dispute rate means reserve expectations are generally minimal. Ensure your payment system can easily integrate with invoicing software, offering detailed descriptions for transactions, which aids in dispute resolution and client reconciliation.
Acquirer and acquirer assessment stance.
Low-risk standard board. These businesses typically have established client relationships and contractual agreements, leading to stable payment flows and low chargeback ratios.
Reserve requirements are generally not necessary.
Dispute and chargeback profile.
Likely reason codes include 13.1 / 4853 (services not as described) and 10.4 / 4834 (fraudulent transaction, if identity theft occurs). 'Services not as described' often stems from disagreements over deliverables, project delays, or perceived quality issues.
Counter with signed contracts outlining scope, change orders, progress reports, communication records, and evidence of service delivery (e. g. , plans, reports). 'Fraudulent transaction' requires robust 3DS2, IP logging, and KYC checks if new clients are involved.

Common questions
What specific B2B payment features are beneficial for project-based services like engineering?
For project-based services, the ability to accept partial payments or milestone-based billing is crucial. Cardflo’s payment gateway supports customisable payment schedules and invoicing integration, allowing merchants to charge clients as project phases are completed, rather than requiring full upfront payment or manual invoicing.
Are there particular considerations for cross-border payments for these professional services?
Cross-border transactions for architectural or engineering services often involve larger sums. Merchants should use acquirers that offer competitive FX rates and support local payment methods in the client's region to minimise conversion costs and maximise approval rates.
Cardflo's multi-currency processing and international acquiring network can address these needs.
How can these merchants mitigate disputes related to service quality or project delays?
Detailed contracts, clear scope of work documentation, and consistent client communication are key. Electronically stored evidence of project milestones, client approvals, and correspondence can be invaluable during a chargeback dispute.
Proactive communication about potential delays can also prevent 'services not delivered' disputes.
For large-scale engineering projects with milestone payments, what is the best strategy to secure payments and minimise friction for B2B clients?
For large-scale engineering projects with milestone payments, implement a tokenisation strategy, allowing clients to securely store card details for future payments without re-entering them. This reduces friction for subsequent milestone billing.
Combine this with 3DS2 for initial payments to confirm cardholder identity, especially for new clients or high-value transactions. Consider offering BACS direct debits or A2A payments for very large sums, as these often have lower processing fees and are preferred by many corporate clients.
Clearly itemise invoices for each milestone payment.
How should an architectural firm handle payment disputes related to changes in project scope or perceived delays by the client?
Payment disputes related to project scope changes or delays require robust documentation. Ensure every alteration to the original project scope is formally documented via a signed change order, clearly detailing additional costs and revised timelines.
Maintain comprehensive records of all communications, meetings, and client approvals throughout the project lifecycle. When a dispute arises, present the original contract, all signed change orders, evidence of work completed as per agreement, and communication logs.
This structured evidence is crucial to demonstrate that services were rendered as agreed, or that changes were approved by the client.
