Merchant Account for a Marketing Agency: Retainers, Ad Spend and Disputes

An agency file is underwritten as a prepaid, intangible, high-ticket service, often paid by a business abroad. The underwriter wants a signed agreement, an invoice per charge and acknowledged monthly reporting. Client ad budgets collected through the agency's MID and paid on to the platforms read as transaction laundering; keep them off the MID. An agency outside the US adds entity, director and bank account with the IBO package.

A merchant account for a marketing agency is underwritten as a high-risk service file: the card is charged before the work is done, the deliverable has no tracking number, the ticket is a retainer or a project fee in the thousands, and the payer is often a company abroad. The underwriter wants an agreement, invoices and monthly reporting that make every charge provable, and a MID that carries the agency's own fees only; client ad budgets passed through the agency's MID read as transaction laundering. An agency outside the US adds the US entity, principal and bank account with an IBO package on the IBO package.

How underwriters read a marketing agency file

Agencies are underwritten as high-risk services for the same structural reason as coaching and consulting: the acquirer settles a charge for work not yet delivered, and if the engagement stops the cardholder disputes it and the acquirer recovers the money from the merchant. Five things make an agency file heavier; beyond them, the reviewer reads the website, the agreement template, processing statements where they exist, and the refund and cancellation terms.

• Ticket size. A retainer or a project fee is thousands of dollars in one card-not-present charge; a single dispute is a large share of the month's volume.
• Business cardholders. A company card is disputed by a finance team reconciling statements against invoices, and each dispute carries a retainer or a project fee.
• Cross-border clients. A high share of cards issued outside the US raises the fraud and dispute expectation; acquirers typically price or cap it and ask where your clients are.
• Intangible deliverables. A campaign, a set of creatives or a report has no courier scan; the file has to show how delivery is recorded and accepted.
• Keyed charges. A retainer keyed into a virtual terminal is a mail order or telephone order transaction with no cardholder-entered data; a payment link the client completes reads better, and applications ask what share is keyed.

Retainers, project fees, commissions and ad budgets: four billing lines

An agency rarely has one revenue line. Each reads differently on a statement, and the last one should not be on the statement at all. Present them separately in the application, each with its agreement clause and invoice format.

Why client ad spend charged through the agency's MID reads as transaction laundering

Agencies that manage client ad accounts often charge the client's card for the monthly media budget, then pay the platforms from their own account. On a statement it shows as volume that is not the agency's revenue, tickets that move with the client's budget rather than the fee, unspent budget coming back as refunds, a gross margin near zero and a handful of cardholders. Transaction laundering is processing the sales of an undisclosed business through another merchant's account; the transaction laundering guide on this blog covers the general case. Media pass-through is its close relative: the MID collects money for a purchase the client makes from a third party, and an underwriter cannot tell the two apart from the statement. The card schemes treat undisclosed aggregation and processing on behalf of others as violations; the consequences run from a request for information to a reserve to termination.

The contract and reporting proof that answers a service dispute

The disputes an agency meets are "services not rendered" and "not as described", plus "cancelled recurring" when a retainer keeps being charged after the client says it stopped. In representment the agency assembles a file an issuer analyst can read quickly: it ties the charge to an agreement, the agreement to a delivery, and the delivery to the client's acknowledgement. An underwriter typically asks for the agreement template and a sample report before the MID opens.

• The signed agreement. Scope, deliverables, term, fee, payment schedule, cancellation notice, treatment of prepaid fees on early termination, and an acceptance procedure, signed electronically with a timestamp and the signer's email.
• A card authorisation on file. For a retainer charged to a stored card, a written consent naming the amount, the frequency and how to cancel; it is the first thing a "cancelled recurring" dispute tests.
• An invoice per charge. Same amount, same date, same period, with the invoice number in the charge data where the gateway allows it.
• Monthly reporting the client received. Screenshots, creatives, published pages, dashboards, timesheets: dated, sent to the client's address, with the reply recorded.
• The approval trail. Kick-off notes, creative approvals, change requests, accepted meeting invitations, project management and shared-drive logs.
• Support history. The client wrote and you answered, or never raised a problem before the dispute.

Two limits. The stack exists only if the agency records it from the first invoice; an approval email cannot be reconstructed later. And no one can promise the outcome: the issuer decides each case, and a company card carries dispute rights like a consumer card. What the clauses are worth in your client's jurisdiction is for a professional; IBOCore gives no legal advice on contracts and does not manage chargebacks.

Descriptor, receipts and cancellation terms: the controls an underwriter checks

Once the agreement and the reporting exist, the remaining disputes come from recognition and cancellation: a finance team sees a charge from a name that does not match the invoice, or a client who asked to stop sees one more retainer charge. Both are avoidable; an underwriter checks the checkout and the terms for these controls.

• Descriptor. The agency's name as it appears on the agreement and the invoice, with the support phone number or website in the descriptor field; the billing descriptor guide on this blog covers the fields.
• Receipts. An emailed receipt for every charge naming the period and the invoice number, sent to the finance contact, not only the marketing contact.
• Cancellation. A written notice period, one cancellation channel and a confirmation email naming the last charge; the final charge after notice is the one clients dispute.
• Refunds. A pro-rata rule for unused retainer time, applied the same way every time; a client refunded the same day has no reason to call the issuer.
• Support. A staffed support email under the agency name with a response time you keep; the customer support requirements guide on this blog covers the floor.
• One name to the client. Website, agreement, invoice, receipt and descriptor carry the same agency name; on the merchant application it sits in the DBA field next to the legal entity name.

Where the IBO package fits, next to coaching and consulting

What an agency outside the US usually cannot produce is the other half of the file: a US entity, a US-resident principal the acquirer can underwrite and a US bank account for settlements. An IBO package supplies it. An IBO (Independent Business Operator) is a real, KYC-verified US resident who acts as the nominee director of a fresh US LLC or C-Corp; every IBOCore director has zero criminal record, a credit score of 650 or more, and serves one merchant only. The package arrives the same day the payment confirms with:

• The US entity with its EIN, incorporated in the director's home state, never a Wyoming shell.
• The complete director and business documentation: government ID, proof of address, articles, operating agreement, EIN letter.
• A business bank account at Bluebanc or Relay with full operational access: inbound and outbound wires, debit card, no minimum balance.
• A professional email on the company domain and a dedicated US residential proxy.
• Director collaboration on verification calls and signatures, with zero interference in the business.
• 24/7 support in a private Telegram group with an account manager.

The IBO package costs $999 setup, then $2,999 per month from 30 days after delivery, whatever the vertical or the billing model. The setup fee is paid in USDT or USDC on ERC20 or TRC20; acquirer onboarding then typically takes 3 to 10 business days, on the acquirer's timeline. Two add-ons fit here: the document template pack ($499, one-time: service agreement, invoice, refund policy and terms of service templates) and merchant account consulting ($899 per month). The state filing and the EIN show the director as the principal. At the time of writing, under FinCEN's interim final rule of March 2025, domestic companies and US persons are exempt from beneficial ownership reporting, while companies formed under foreign law that register in a US state remain subject to it; verify current FinCEN guidance and let a professional decide what applies to you, as IBOCore gives no legal or tax advice.

Questions merchants ask

Can I charge my clients' ad budgets to their card and pay the platforms myself?

Not through a MID underwritten for agency fees. Media pass-through is money collected for a purchase the client makes from a third party, and on a statement it reads as transaction laundering. The clean arrangement is the client's own ad account, funded by the client's own card, with the agency as manager. If managing budgets is central to your offer, disclose it and let the acquirer price it.

Is a monthly retainer subscription billing?

It depends on how the charge happens. A retainer invoiced each month and paid on that invoice, or a defined engagement billed in a fixed number of instalments, is service billing on the IBO package. A card stored on file and charged automatically until the client cancels is recurring billing.

Do business clients paying with a company card still charge back?

Yes. A company card carries dispute rights, and each dispute is a retainer or a project fee, so one dispute matters more on an agency MID. The person disputing is often in finance, reacting to a descriptor they do not recognise or to a charge after a cancellation. The same stack answers them: agreement, card authorisation, invoice, reporting and approval trail. No one can promise the outcome; you control whether the file exists when the dispute lands.

High-risk MID metrics acquirers watch

Once live, your chargeback ratio (CB ratio) is chargebacks divided by transactions; Visa VDMP and Mastercard ECP programs trigger when you breach network thresholds. Rolling reserves (often 10% for 180 days) protect the acquirer against future disputes. MATCH (Terminated Merchant File) is the industry blacklist after a forced termination. MCC (Merchant Category Code) must reflect your real vertical; miscoding is a scheme violation.

• Representment: fighting a chargeback with delivery proof and logs.
• RDR / Ethoca alerts: pre-chargeback refund tools that protect your CB ratio.
• Statement descriptor: keep it recognizable to cut "friendly fraud" disputes.
• Processing cap: volume limit until the acquirer trusts your history.

MID stacking without structure

Spreading volume across many MIDs without separate entities looks like ratio gaming or transaction laundering to risk teams. The durable pattern is one IBO package per MID, clean descriptors, honest MCC, and reserves treated as a cost of doing high-risk volume.

FAQ: quick answers

How fast can I get an IBO package on IBOCore?

Available inventory ships the same day after payment. You receive Articles, EIN letter, registered agent details, bank onboarding pack and signer contact through your merchant dashboard. Processor onboarding typically follows over the next one to two weeks.
