What MCC 1771 covers
Merchant Category Code 1771 is the ISO 18245 identifier used by the card networks for concrete work contractors. Acquirers, issuers and regulators use this code to set interchange, scheme fees, fraud rules and reporting categories for every transaction your business processes.
Foundations, slabs, driveways and concrete construction. Choosing the right MCC is critical: an incorrect code can lead to higher interchange, surcharges, or, in regulated categories, declined transactions and account holds.
MCC 1771 includes concrete contractors specialising in foundations, slabs, driveways, and other concrete construction.
These businesses typically serve both residential and commercial sectors, with ticket sizes varying greatly depending on the project scale, from small domestic patios (hundreds) to large commercial foundations (tens of thousands or more).
Transaction frequency is generally low to medium, often tied to project phases (deposit, interim payments, final payment). Chargebacks are not common in this MCC.
When they occur, they typically relate to disputes over the quality of work (e. g. , cracking, incorrect grading) or failure to complete the project as contracted. The majority of payments are likely card-not-present, taken over the phone, or via online invoicing.
This MCC does not fall under any specific scheme programmes. Visa and Mastercard use standard B2B/consumer transaction categorisation.
Cardflo provides these merchants with secure and flexible payment solutions, including APIs for integrating payment forms on their websites for deposits, or virtual terminals for remote payment processing via phone.
Concrete contractors should optimise acceptance for project-based payments, favouring e-invoicing for deposits and interim stages, and mobile POS for on-site final payments.
Given varying ticket sizes, from hundreds to tens of thousands, ensure your payment gateway supports flexible transaction limits and robust 3DS2 for high-value CNP transactions. Lower transaction frequency suggests focusing on customer communication to prevent disputes over work quality.
Acquirers generally view this MCC as low-risk, so expect competitive rates and minimal reserve requirements, but be prepared to evidence work completion to protect against chargebacks.
Acquirer and acquirer assessment stance.
Low-risk standard board. This industry generally carries a low fraud risk.
Standard underwriting and pricing models apply. Reserves are seldom imposed, given the nature of the service.
Dispute and chargeback profile.
The most likely chargeback reason codes for concrete work are 13.1 / 4853 (services not as described) or 13.3 / 4855 (non-receipt of goods or services).
These typically occur when a client alleges the quality of concrete work (e. g. , cracking, incorrect grading) is substandard, or the project was unfinished.
To defeat these, provide signed contracts detailing scope, change orders, photographic evidence of completed work, daily logs, client sign-offs at project milestones, and any communication correcting client expectations.

Common questions
What are the most common chargeback issues for concrete contractors and how can they be prevented?
Common issues include 'Services Not Provided' (Reason Code 4855 / 13.3) or 'Defective Merchandise/Services' (Reason Code 4834 / 13.1) if the concrete subsequently fails. Prevention involves clear contracts, detailed specifications, photographic evidence of site preparation and finished work, and client sign-off upon project completion.
Ensuring proper ground preparation and materials also technically mitigates service quality issues.
For large concrete pour projects, what is the safest way to accept large-value payments?
For substantial payments related to large concrete projects, encouraging bank transfers reduces card processing fees and provides finality of payment. If cards are preferred, using a 3D Secure authenticated payment link or virtual terminal for remote collection helps transfer liability for fraud to the issuer.
Ensure funds are cleared before commencing work in full.
How can I provide digital invoices and payment options to my clients in MCC 1771?
Digital invoices incorporating direct payment links are highly effective. These links allow clients to pay using their preferred card or digital wallet securely online.
Cardflo's payment link solution can be integrated into your invoicing software or used as a standalone tool, offering a professional and convenient payment experience.
How can I best handle progressive payments for large concrete projects to mitigate dispute risk and transaction fees?
For large concrete projects, structure your payment schedule into clear, milestone-based invoices through your e-invoicing system. Ensure each invoice clearly itemises the work completed for that stage and ties back to the original signed contract.
Utilise Level 2/3 data if available, to provide acquirers with enhanced transaction details, which can sometimes reduce interchange costs. Mandate client sign-off on completed milestones before invoicing for the next, providing a strong defence against 'services not as described' chargebacks.
For high-value transactions, always implement 3DS2 to shift liability for fraudulent non-authenticated disputes.
What specific operational evidence should I collect for concrete jobs to defend against chargebacks claiming poor workmanship or non-completion?
To defend against disputes asserting poor workmanship or non-completion, maintain thorough project documentation. This should include detailed contracts specifying the scope of work, materials, and quality standards.
Critically, capture high-resolution, timestamped photographs or video of the site before, during, and after key stages of concrete pouring and curing. Obtain client sign-offs or completion certificates upon project milestones and final completion.
Retain all communication logs, including emails or messages, addressing client concerns or approving variations. This comprehensive evidence package proves service delivery and conformance to agreed standards.
