Using a Client's Credit Card for Facebook Ads: The Agency Guide
Every agency hits this question by month two: should you put your client's Facebook ads on their credit card, or float the spend on yours and invoice it back? Each side has a real case. Get the structure wrong and you either lose tens of thousands in points, expose yourself to client chargebacks, or trigger a Meta restriction that takes down both accounts. Here's the playbook.

The two models: pass-through vs float-and-invoice
Pass-through means the client's card lives on their ad account, Meta charges them directly, you never touch the money. Float-and-invoice means your agency's card pays Meta, then you invoice the client for spend plus your management fee. Pass-through is simpler legally and avoids cashflow risk. Float-and-invoice gives you the points (potentially $20-100K/year on a real agency book), full visibility into billing, and lets you negotiate better rates with Meta reps who see consolidated volume — but it puts the spend on your balance sheet until invoices clear.
The correct Business Manager structure for pass-through
Client owns their own Business Manager. They create an Ad Account, add their credit card to it, and grant your agency Business Manager Partner access with the 'Advertise' role on that ad account only. You manage campaigns; they own the asset and the billing. Critical: do NOT add your agency as the ad account owner, and do NOT add the client's card to an ad account your agency owns. Cross-ownership of card and account is what triggers Meta's 'unauthorized use of payment method' restriction.
When float-and-invoice is worth the risk
Float makes sense when (1) your agency has >60 days of operating cash to cover a full ad cycle if a client pays late, (2) your management contract includes a retainer or upfront ad-budget deposit, (3) your monthly volume per client exceeds $5K — below that, the points don't justify the cashflow drag. At $30K/month per client across 10 clients, floating earns roughly $24K/year in points on an Amex Business Gold or Chase Ink stack. At $3K/month per client, the same model earns $2,400/year and isn't worth one late-paying client wiping out a month of cash.
Contract clauses that protect the agency when floating
Three clauses are non-negotiable: (1) net-7 or net-14 payment terms with explicit late fees and the right to pause ads on missed payment, (2) an upfront ad-spend deposit equal to one billing cycle held against the account, (3) explicit acknowledgment that the agency is the merchant of record for Meta charges and that the client waives chargeback rights for documented ad spend. Without #3, a single bad-faith client can file a $50K chargeback on your business card and freeze your entire stack while it's investigated.
The tax treatment matters more than people think
Float-and-invoice means the full ad spend flows through your P&L: it's revenue on the invoice and expense on the card. This inflates gross revenue (useful for valuation, problematic for tax brackets in some jurisdictions). Pass-through keeps ad spend off your books entirely — your revenue is just the management fee. Talk to your accountant before defaulting to either model; the right answer depends on your entity type, country, and growth-vs-margin priorities.
The hybrid model most established agencies actually run
By year two, most agencies converge on a hybrid: pass-through for new clients (under 6 months, under $10K/month spend, no deposit), float-and-invoice for established clients (proven payment history, signed long-term contracts, deposit on file). This caps cashflow risk on unknown clients while capturing points on the predictable bulk of the book. It's also the structure that scales cleanest past 20 clients without your accounting team revolting.
Takeaway
Default to pass-through (client's card, client's Business Manager, you have Partner access) unless you have the cash, contracts, and volume to float responsibly. The points are real and worth chasing — but only on top of solid contracts and clients who actually pay on time.
