Invoice factoring vs merchant cash advance is a choice between two fast forms of business funding repaid from different money: factoring advances cash against invoices already issued to other businesses, while a merchant cash advance (MCA) provides a lump sum in exchange for a share of sales the business has yet to make. Both are priced as a fee rather than as interest, and on FundBetter's programs both can fund in as little as 24 to 48 hours for factoring and 24 hours for an MCA.
The simplest test is who pays the money back: with factoring, your customer; with an MCA, your business, out of its own future sales. For lines of credit and term loans, see FundBetter's guide to line of credit vs short-term loan vs merchant cash advance.
Receivables versus future sales
Factoring starts with work that is finished and billed. FundBetter describes eligible invoices as completed work billed to businesses or government agencies, with clear terms and no dispute, and says progress bills, retainage and consumer invoices are harder to advance. Because repayment comes from the customer, approval leans on the credit of the customers who owe you.
An MCA starts with sales that have not happened yet, so underwriting looks at the business's own sales. FundBetter says card and deposit volume matter more than credit score and that advances are sized against monthly sales volume.
That difference shapes fit. FundBetter puts it directly: "Factoring is built for B2B receivables, and a merchant cash advance suits card-paying customers better." A distributor billing on Net 30 carries a ledger a factor may be able to advance against, while a restaurant or salon paid at the register may have few receivables but steady card volume.
In the Federal Reserve Banks' 2026 Report on Employer Firms, drawn from the 2025 Small Business Credit Survey, 8 percent of employer firms applied for a merchant cash advance in the prior 12 months and 3 percent sought factoring, against 26 percent that applied for a loan.
| Feature | Invoice factoring | Merchant cash advance |
|---|---|---|
| What is advanced against | Completed invoices to business or government customers | A share of future card sales |
| Whose credit carries the most weight | Mainly your customers' | Your sales and deposit history, along with your own credit |
| How much | Up to 90 percent of invoice value, with the rest held in reserve | Sized against monthly sales volume |
| Who pays it back | Your customer, by paying the invoice | Your business, from future sales |
| How it is priced | A discount fee, roughly 1 to 3 percent for the first 30 days, then an increment per additional period | A factor rate, commonly 1.1 to 1.5, fixed when you sign |
| If payments slow | The fee keeps accruing while the invoice is unpaid | The total stays the same; on a true holdback the payoff takes longer |
| Built for | Businesses that bill other businesses | Businesses paid by card at the point of sale |
How each one is repaid
Once an invoice is factored, the business largely steps out of repayment. FundBetter says most arrangements are notified, so the customer is told to pay a new account. When the customer pays, the reserve comes back minus the fee, and a late payment raises the fee because it accrues while the invoice stays open. If the customer never pays, recourse terms let the invoice be charged back after an agreed period, commonly 90 days, while non-recourse usually covers only customer insolvency.
An MCA is repaid by the business itself. FundBetter describes a holdback, often somewhere between 5 and 20 percent of card sales, taken automatically with remittances usually daily or weekly. With a true holdback, a slow sales day produces a smaller payment. Some advances instead collect a fixed daily or weekly bank debit that does not move with sales, so ask which structure an offer uses and whether it includes a reconciliation provision, which FundBetter says not every agreement has.
Under either structure the total is fixed on day one by the factor rate, so a slow stretch on a true holdback lengthens the term without raising what you owe.
What each costs on roughly $100,000 of funding
FundBetter itself calls the advance "the most expensive product on our shelf" and adds that "if you bill other businesses, invoice factoring is cheaper still."
Imagine a hypothetical wholesale food distributor that needs about $100,000 for a seasonal inventory order, could qualify for either product (including, for this comparison, enough card sales to qualify for an MCA), and has $110,000 in open Net 30 invoices to grocery and restaurant customers.
On the factoring side, FundBetter allows an advance of up to 90 percent, which on $110,000 puts $99,000 in the account, slightly less than the $100,000 target, and holds $11,000 in reserve. Assume 2 percent for the first 30 days and, since FundBetter does not fix the size of later increments, a hypothetical 1 percent per additional 15 days. If customers pay on day 30, the fee is $2,200 and $8,800 of the reserve comes back; on day 45, the fee is $3,300. As a simple annualized cost illustration on the cash advanced, $2,200 for 30 days on $99,000 is 2.22 percent, or about 27 percent a year (2.22 percent times 365, divided by 30). That excludes any setup, wire, lockbox or minimum volume fees, which FundBetter lists as possible.
On the MCA side, take a $100,000 advance at a factor rate of 1.25. The total repaid is $125,000, so the cost is $25,000, fixed at signing. Collected over 52 weekly payments of about $2,403.85, assuming equal weekly payments and no origination or other fees, that is a weekly periodic rate of 0.87833 percent and a nominal APR of 45.67 percent, calculated from the weekly cash flows on a declining balance. Over 26 weeks, at about $4,807.69 a week, the same $25,000 works out to a nominal APR of 89.90 percent, because the cost is fixed while the time shrinks.
Dollar totals mislead here: the $2,200 buys about a month of cash on one batch of invoices, while the $25,000 covers a balance repaid over a year. The annualized figures are built differently, so treat them as a rough guide rather than equivalent APRs. The factoring figure annualizes one fee against the cash advanced, while the MCA figures come from the timing of every weekly payment. On these assumptions, with no other fees, the factoring illustration comes to about 27 percent, against about 46 percent for the MCA over 52 weeks or about 90 percent over 26. A faster-paying customer or a higher first-period fee would raise the factoring figure, and a standardized comparison of two real offers would model the timing of all their cash flows. FundBetter's merchant cash advance calculator runs this conversion on an offer you are weighing.
Factoring while you still carry an MCA
FundBetter lists an existing advance among the situations where a second MCA does not fit, since a second holdback would squeeze payroll. Factoring draws on a different source of repayment, but the existing advance can still get in the way.
The sticking point is the claim on receivables. An MCA agreement may give the funder a security interest in receivables, often made public through a UCC financing statement filed with the state. FundBetter says any invoice already pledged to another lender can't be factored until that claim is released. An MCA funder whose agreement covers receivables would need to resolve its claim to the factor's satisfaction, through a release, subordination or carve-out.
This can sometimes be worked out, though nothing is guaranteed. The advance may be paid off from the first factoring advance in exchange for a release of the filing, which may cost the full remaining balance, since the MCA total was fixed on day one, unless the contract offers a prepayment discount. Alternatively, the MCA funder may agree in writing to subordinate its claim or release the specific invoices being factored. Some MCA agreements may also limit selling receivables or taking on more financing, so read yours closely and disclose the advance at the start of a factoring application.
Choose Between Factoring and an MCA with FundBetter
FundBetter is a national small business lender and funding marketplace, founded in 2018 and based in Miami. It may fund directly or connect a business with third-party lenders and funding partners, depending on which is the better fit, with funding from $5,000 to $5 million across eight products. Factoring is assessed differently from the other products: the weight sits on your B2B invoices and the credit quality of the customers behind them rather than on your own financial profile alone. FundBetter's factoring criteria start at six or more months in business and center on eligible B2B or government invoices and a creditworthy customer base. Invoice eligibility, concentration and any existing liens on receivables also affect what can be funded. The merchant cash advance program sits higher, at six or more months in business, $15,000 or more in monthly card sales, and a personal credit score of 520 or above. Those are FundBetter's criteria rather than general lending requirements, and they vary by product. Checking your options uses a soft inquiry that does not affect your credit score; a hard inquiry happens later, with your permission, only on certain offers.
A business with open invoices to creditworthy commercial customers can start with invoice factoring. A business paid mainly by card can review the merchant cash advance terms and run any offer through the calculator first.
