Payment Facilitator (PayFac) vs Merchant Account
What a payment facilitator is, how PayFacs like Stripe and Square differ from a merchant account, plus costs, payout holds and when to switch.
A payment facilitator (PayFac) is a company that holds one master merchant account with an acquiring bank and signs up many smaller businesses underneath it as sub-merchants. Stripe, Square and PayPal are the best-known examples. A traditional merchant account, by contrast, gives your business its own merchant ID and its own contract with an acquirer after full underwriting. The PayFac route is faster and simpler; the merchant account route usually costs less at higher volume and gives you more control.
If you have ever opened a Stripe account in ten minutes and taken a card payment the same day, you have used a payment facilitator. This guide explains how the model works, what you give up for that speed, how pricing compares, and the signals that it is time to move to a dedicated merchant account. For the broader terminology, see our explainer on merchant accounts vs payment processors.
How the payment facilitator model works
Card payments involve the cardholder's bank (issuer), the card network, an acquiring bank and the merchant. Acquirers are responsible for the merchants they sign up, so historically every business had to be individually underwritten. The PayFac model, which the card networks formalized in the 2010s, lets a registered facilitator take on that role for many small merchants:
- The PayFac registers with Visa and Mastercard through a sponsoring acquirer and holds a master merchant account.
- You sign the PayFac's sub-merchant terms online and pass its automated identity and business checks.
- Your card payments are processed under the PayFac's master account.
- The PayFac collects the funds, deducts its fees and pays out to your bank account.
- The PayFac monitors your activity and carries the risk if you generate chargebacks or fraud you cannot cover.
The $1 million threshold
Card networks expect sub-merchants that grow large to have a direct relationship with the acquirer. Mastercard set its sub-merchant threshold at $1 million in annual Mastercard volume, as Digital Transactions reported, and acquirer agreements commonly cite about $1 million for Visa and Mastercard. In practice, your PayFac handles this transition, often by having you accept additional terms with its partner bank. Most small businesses never reach it.
Payment facilitator vs merchant account compared
| Factor | Payment facilitator (Stripe, Square, PayPal) | Dedicated merchant account (via bank or ISO) |
|---|---|---|
| Approval time | Minutes to a day | Several days to a few weeks |
| Underwriting | Light at sign-up, ongoing automated monitoring | Full up front: statements, financials, owner credit |
| Pricing | Flat rate, e.g. 2.9% + 30 cents online | Interchange-plus or tiered, often lower at volume |
| Monthly fees | Usually none on basic plans | Often statement, PCI, gateway or minimum fees |
| Contract | Month to month | Sometimes multi-year with early termination fees |
| Fund holds | More likely after sudden changes in activity | Risk assessed at approval; reserves set up front |
| Merchant ID | Shared master account | Your own MID |
| Best for | New, small, variable-volume and online businesses | Established businesses with steady, larger volume |
What does each option really cost?
Flat-rate PayFac pricing bundles interchange, network assessments and the provider's margin into one number. At the time of writing, Stripe lists 2.9% plus 30 cents for standard online US card payments; our Stripe fees guide and Square invoice fees guide break down the variations for in-person, international and invoice payments.
Merchant accounts more often use interchange-plus pricing: you pay the actual interchange (which varies by card type) plus a fixed markup, for example interchange plus 0.3% and 10 cents. Average interchange on consumer credit cards is often below 2%, so the total can undercut a flat rate, especially if many customers use debit cards, which carry low interchange for large issuers.
Worked example: $50,000 a month in card payments
Illustrative figures for a business processing $50,000 a month across 500 transactions (average ticket $100):
| Cost item | PayFac flat rate (2.9% + $0.30) | Merchant account (interchange + 0.30% + $0.10) |
|---|---|---|
| Percentage fees | $1,450 | Interchange about $900 (assumed 1.8% blend) + markup $150 |
| Per-transaction fees | $150 | $50 |
| Monthly and PCI fees | $0 | $40 (assumed) |
| Total monthly cost | $1,600 (3.2% effective) | $1,140 (2.28% effective) |
| Annual difference | About $5,520 in favor of the merchant account in this example | |
Change the assumptions and the gap shrinks or grows. A business with $5,000 a month in volume would save perhaps a few hundred dollars a year at most, which rarely justifies extra fees, a contract and more paperwork. Always compare using your real statements; our processing fees explainer shows how to calculate your effective rate.
Pros and cons of using a payment facilitator
Advantages
- Instant onboarding. Start accepting payments the day you start your business.
- Built-in tools. Payment links, invoices, subscriptions, a virtual terminal and card readers in one dashboard.
- Predictable pricing. One rate is easy to quote into your prices.
- No long contract. Leave whenever you want.
Disadvantages
- Higher cost at volume. You pay the same flat rate on cheap debit transactions as on premium rewards cards.
- Risk of sudden holds. Because underwriting happens after the fact, a large first invoice or a spike in sales can trigger a payout pause.
- Less support. You are one of millions of accounts.
- Restricted industries. Many PayFacs prohibit or restrict businesses considered risky; those businesses need a high-risk merchant account instead.
How to avoid payout holds with a PayFac
- Describe your business accurately at sign-up, including typical ticket size and delivery timelines.
- Warn your provider before big jobs. If you usually invoice $800 and suddenly bill $25,000, tell support first.
- Keep documentation. Signed contracts, detailed invoices, proof of delivery and client communication answer most risk reviews.
- Keep chargebacks low. Clear descriptors and refund policies help; see our guide on handling chargebacks.
- Use ACH for large B2B invoices. Bank payments cost less and are less likely to trigger card-risk rules.
When to move to a merchant account
Signs that a dedicated merchant account is worth quoting:
- Steady card volume in the hundreds of thousands of dollars a year or more.
- A high share of debit or business cards where interchange-plus pricing saves the most.
- Repeated holds or reserves from your PayFac despite a clean record.
- A need for a dedicated account manager, custom funding schedules or specific industry support.
Get at least two interchange-plus quotes, read the contract for early termination and monthly minimum fees, and confirm PCI compliance requirements; our PCI compliance guide explains the questionnaires you may be asked to complete. If you want to cut costs without switching, a cash discount program can offset fees on card payments.
PayFac vs ISO vs aggregator: the terms explained
Processor sales pages use these words loosely, so here is how they usually differ:
| Model | Who holds the merchant relationship | Your merchant ID | Typical example |
|---|---|---|---|
| Payment facilitator | The PayFac, under its sponsoring acquirer | Sub-merchant under the PayFac's master account | Stripe, Square, PayPal for small sellers |
| Independent sales organization (ISO) | The acquirer; the ISO sells and services the account | Your own MID | Local merchant services reseller |
| Direct acquirer relationship | The acquiring bank or processor | Your own MID | Large retailers and high-volume merchants |
| Marketplace or merchant of record | The platform sells to the customer itself and pays you | None; the platform is the merchant | App stores, some digital product platforms |
The merchant of record model is worth knowing if you sell digital products internationally: the platform, not you, is the seller on the card statement and usually handles sales tax or VAT, in exchange for a higher fee.
Should your own business become a payment facilitator?
Software companies that serve other businesses, such as booking tools for salons or invoicing platforms for contractors, sometimes consider becoming a PayFac to earn revenue on their users' payments. Full registration means taking on underwriting, risk monitoring, chargeback liability, demanding PCI compliance obligations and a contract with a sponsoring acquirer, which requires significant capital and staff. Most smaller platforms instead use an embedded payments product, such as Stripe Connect or similar offerings, which lets them add payments to their software and share revenue without becoming the registered facilitator. For an ordinary service business, none of this is necessary; you simply choose between being a sub-merchant or having your own merchant account.
Questions to ask before you sign with any provider
- What is my effective rate at my real card mix, including monthly fees?
- How fast are payouts, and what triggers a hold or reserve?
- Is there a contract term, early termination fee or equipment lease?
- How are chargebacks handled, and what does each one cost?
- Can I export transactions to my accounting software for bank reconciliation?
- Does the provider support invoice payment links, ACH and recurring billing?
Where your invoices fit in
Whichever model you use, the invoice is the document that links a payment to a job. Put your payment link or bank details on every invoice, use clear invoice numbers that match the payment reference, and keep copies; they are the first thing a PayFac asks for during a risk review and the first thing you need in a dispute.

Frequently asked questions
Is Stripe a payment facilitator?
Yes. Stripe, Square and PayPal work on the payment facilitator model for most small businesses: they hold a master merchant relationship with acquiring banks and onboard you as a sub-merchant under it. That is why you can sign up in minutes without a separate merchant account application. Larger businesses can sometimes negotiate custom pricing or different structures with these providers, but the default small-business setup is a sub-merchant account under the provider's master account.
What is the difference between a PayFac and an ISO?
An ISO (independent sales organization) resells merchant accounts on behalf of an acquiring bank. Each business still gets its own merchant ID and its own agreement with the acquirer, after underwriting. A payment facilitator instead signs up businesses as sub-merchants under its own master merchant account, handles underwriting itself and often pays out funds directly. ISOs usually take longer to approve you but can offer custom pricing; PayFacs are faster and simpler but use standardized pricing.
Why did my payment facilitator freeze my funds?
Because the PayFac carries the risk for every sub-merchant, its systems watch for sudden volume spikes, unusual ticket sizes, high refund or chargeback rates, and business types it considers risky. When something looks off, it may hold payouts, add a reserve or ask for documents such as invoices, contracts and delivery proof. Respond quickly with clear documentation. Keeping professional invoices and signed agreements for large jobs makes these reviews much faster to resolve.
When should I switch from a PayFac to a merchant account?
Consider it when your card volume is large and steady enough that interchange-plus pricing would save meaningful money, when your average ticket is high, or when you need more stable funding and a dedicated relationship. Many businesses start comparing quotes somewhere in the hundreds of thousands of dollars per year in card volume. Card network rules also generally require a direct merchant agreement once a sub-merchant passes about $1 million in annual volume on a network.
Are payment facilitator fees negotiable?
Standard published rates, such as Stripe's 2.9% plus 30 cents for online US cards, apply to most small businesses and are rarely negotiable at low volume. Once you process significant volume, Stripe, Square and others may offer custom or interchange-plus pricing on request. It is worth asking once your monthly volume is substantial and stable, and bringing a competing merchant account quote to the conversation.
Can I use a payment facilitator and a merchant account at the same time?
Yes. Many businesses keep a PayFac for online checkout or invoice payments and a traditional merchant account for in-person or high-ticket transactions, or the reverse. Running two providers adds reconciliation work, so tag each payment by source in your bookkeeping. Make sure invoices tell clients exactly which payment link or method to use, so payments do not land in the wrong account.
