Lenders size an agency's line on its own fee income and on receivables net of the media and production it still owes vendors, not on gross billings. The ledger mixes the agency's fees with pass-through costs it bills to clients and owes to publishers. A lender typically advances 80% to 90% of eligible receivables but reserves against the unpaid media payables tied to them, and caps any one client, commonly at 20% to 25% of eligible receivables. That cap bites hard in agencies, where a few clients are often most of the billings. With no hard assets, the line leans on retainer income, client contracts and the founders' guarantees.

Gross billings are not revenue
Suppose an agency invoices a client 1,000 for a month's campaign. Of that, 800 is media bought from publishers, broadcasters or ad platforms, 50 is production from outside vendors, and 150 is the agency's own fee. The agency's accounts receivable show 1,000. Its revenue, in the sense a lender cares about, is 150. The other 850 is money in transit from the client to someone else.
A lender reads every agency's books with that split in mind. It wants to know how the agency earns its 150: monthly retainers, project fees billed on milestones, commissions or markups on media, or performance fees tied to results. And it wants to know how the 850 moves: who pays the media vendor, when, and whether the agency owes that vendor even if the client never pays.
That last point turns on the contract. Some media agreements make the agency liable only once the client has paid it; others make the agency liable regardless. Many digital ad platforms charge the agency's card as spend accrues, and extend monthly invoicing only to agencies they have approved for credit. A lender will read those terms, because they decide whether a client's failure costs the agency its fee or its fee plus the media.
The media float, in plain numbers
Using the same 1,000 campaign, here is how three common arrangements look to the agency's cash and to its line.
| Arrangement | When the agency pays the 800 of media | When the client pays the 1,000 | What the line sees |
|---|---|---|---|
| Platform charges the agency as spend accrues | While the campaign runs, before the client is billed | After the campaign, on the client's terms | A 1,000 receivable the agency has already funded; it supports borrowing in full at the advance rate |
| Publisher bills the agency after the run | After the publisher's invoice falls due | Often later than that, on the client's terms | A 1,000 receivable, less a reserve for the 800 still owed to the publisher |
| Client prepays media | From the client's prepayment | Before the campaign | No receivable; the prepayment is a liability until the media is bought |
The pattern is the point. A line against agency receivables can fund media the agency has already paid for, and it can bridge the gap when clients pay later than publishers must be paid. What it will not do is let the agency borrow against the media portion of an invoice and spend the proceeds on payroll while the media bill is still outstanding. Lenders prevent that with a reserve against media payables, explained in availability reserves, or by netting unpaid media out of eligible receivables.
Before any lender asks, know how much media you owe, to whom and when, against which client invoices.
What counts in the borrowing base
The general rules in eligible vs ineligible receivables apply, with a few that matter more for agencies:
- Invoices more than 90 days past invoice are typically ineligible. Large consumer brands that impose long payment terms push invoices toward that line even when they always pay.
- Media that has run but is not yet billed, often because the agency is waiting for the publisher's proof of delivery, is not a receivable until the client invoice goes out.
- Credits, make-goods and billing adjustments reduce what clients actually pay. Lenders measure them as dilution and lower the advance rate if they run high.
- Client prepayments and deposits are liabilities, not assets, and some lenders require them to be held apart.
- Clients above the concentration cap. The excess over the cap, commonly 20% to 25% of eligible receivables, is ineligible.
Concentration is the agency lender's central issue. Many agencies earn most of their fees from a handful of clients, and one client's media can make up most of the receivables in a heavy month. A lender may accept a higher cap for a large, creditworthy client, but only case by case, and it will read that client's contract: its term, the notice period to terminate, and whether the agency is agency of record or one of several on a roster. Losing a client in an agency review can take out a large part of the borrowing base and the fee income in the same stroke; see customer concentration and debt.
Which lender, and how the line is sized
Most independent agencies borrow from banks on a cash-flow line, sized to the agency's net fee income and tested for debt service coverage; conventional banks commonly look for at least 1.25x. The receivables formula sits behind it as a ceiling. Agencies that buy large volumes of media, where the float between paying publishers and collecting from clients is the real need, are more likely to use an asset-based lender whose line tracks the receivables week by week. The trade-offs are in asset-based vs cash-flow lines.
| Agency profile | What drives the line | What the lender watches |
|---|---|---|
| Retainer-based creative or brand agency | Net fee income and coverage | Retainer renewals, client tenure, founder dependence |
| Digital performance agency buying ad spend | The media float between platform charges and client payment | How much spend runs on the agency's card and how fast clients pay |
| Media-buying agency with large pass-through | Receivables net of media payables | Media payables aging, vendor liability terms, concentration |
| Project-based production or events agency | Milestone billings and deposits | Deposits taken versus costs committed before the event or shoot |
Seasonality shapes the request. Agencies with retail and consumer clients see media spend peak in the holiday season, with collections arriving in the new year, just as many clients reset budgets. A line sized for an average month may run out in the one month that matters; see seasonal lines of credit.
Covenants, reporting and controls
Expect a monthly borrowing base certificate with the client aging, and, for agencies with meaningful pass-through, a media payables aging alongside it. Asset-based lenders add periodic field exams that test whether media invoices were paid on time. Covenants typically include debt service coverage, limits on distributions and on other borrowing, and notice to the lender when a significant client gives notice. Some lenders also require client media funds to sit in a separate account, which protects the agency as much as the lender.
What trips agencies up
- Spending media money. An agency that uses a client's media payment to meet payroll, planning to pay the publisher from next month's collections, is borrowing from its vendors. It works until a client leaves and the media bill comes due with no cash behind it.
- Revenue reported gross. Financial statements that count pass-through media as revenue make the agency look larger and its margins look thin. Lenders restate to net fee income; presenting it that way from the start avoids confusion.
- Ad spend on the owner's card. Running platform spend through a personal or corporate card hides a real payable from the balance sheet and the lender.
- A client review. An agency that loses its largest account in a review can lose its coverage and its borrowing base together. Lenders ask when each major contract was last competed.
- Founder-held relationships. If clients stay because of one person, the lender asks what happens without them, and may ask for key-person insurance.
- Cash advances to cover a slow client. A merchant cash advance taken while waiting for a large invoice is expensive, usually breaks the line's covenants, and rarely solves a timing problem a properly sized line would have.
The documents follow Transparent's line of credit checklist: an AR aging by client with days outstanding, the AP aging (which, for an agency, shows the media payables), the balance sheet, the P&L and a year-to-date P&L through last month-end, and a debt schedule showing existing liens, plus bank statements and two to three years of business tax returns where available. For an agency, add revenue by client, split between fees and pass-through, and the principal client contracts. Transparent's book of 1,800+ lenders includes 235 that write asset-based lending and lines. Buyers of an agency should also read financing a marketing agency acquisition and SBA lending to advertising agencies.
Common questions
- Will a lender count the media portion of our receivables?
- Yes, if the agency has already paid the media, since the receivable then replaces cash the agency spent. If the media bill is still unpaid, lenders reserve against it or net it out, so the media portion supports little or no borrowing.
- Our largest client is most of our billings. Can we still get a line?
- Usually, but the line will be smaller than the receivables suggest, because the excess over the single-client cap, commonly 20% to 25% of eligible receivables, is ineligible. Some lenders raise the cap for large, creditworthy clients case by case.
- Should our financial statements show revenue gross or net?
- Lenders analyze agencies on net fee income, so present both: gross billings for scale and net revenue for performance. Follow your accountant on how the statements are prepared, and show the lender the reconciliation.
- Can the line fund ad spend on digital platforms?
- It can bridge the time between paying a platform and collecting from the client, once the client invoice is out. On a borrowing base line, it cannot fund spend for campaigns that have not been invoiced, or for clients the lender has excluded.
- Do we need a separate bank account for client media funds?
- Some lenders require one, and it is good practice regardless. Keeping client media money apart makes it much harder to spend it on the agency's own costs by accident.
