The 60-second answer
A merchant cash advance and a revenue-based financing advance are structured similarly — both purchase future receivables, both avoid the loan/APR framework, both are non-bank capital products. The mechanical difference matters more than the legal one:
- MCA: fixed daily ACH withdrawal regardless of revenue, factor rates of 1.28–1.45, terms of 6–12 months
- RBF: fixed percentage of daily revenue (typically 5–12%), effective cost of 1.10–1.25, terms variable based on actual revenue
For most ecommerce businesses doing $40K+/month with steady revenue, RBF is the cheaper product. For urgent capital needs, businesses with channel mix that platform RBF cannot underwrite, or volumes above $250K/month where RBF caps too low, MCA still wins. The rest of this article walks through the decision tree with real numbers.
How the math actually works
MCA: fixed daily, fixed total
A $100,000 MCA at a 1.34 factor on a 9-month term:
- Total payback:
$100,000 × 1.34 = $134,000 - Fee:
$34,000 - Term: 9 months = approximately 189 business days
- Daily ACH:
$134,000 ÷ 189 = ~$710/day - Monthly outflow: approximately $15,500/month
The $710 hits your account every business day whether you sold $4K that day or $400. Slow weeks compound into cash crises. Strong weeks feel like free money, but the total payback never changes.
RBF: percentage of revenue, variable term
A $100,000 RBF advance at a 10% revenue share with a 1.20 cap:
- Total payback:
$100,000 × 1.20 = $120,000 - Fee:
$20,000 - Revenue share: 10% of daily incoming settlements (Shopify, Stripe, Amazon)
- Implied term: depends on actual revenue — at $100K/month revenue, paid back in about 12 months; at $150K/month, paid back in about 8 months
- Daily payment if you do $5K that day:
$500 - Daily payment if you do $1K that day:
$100
The fee is fixed in dollars but the cash impact tracks your actual revenue. Slow weeks remain manageable. Strong weeks repay the advance faster, which is more efficient than an MCA where you cannot meaningfully accelerate repayment.
The cost comparison in one chart
On a $100K advance, the typical 2026 spread:
- Platform RBF (Shopify Capital, Stripe Capital, Square Capital): $108K–$118K total payback (1.08–1.18 cap)
- Standalone RBF (Wayflyer, Clearco, Settle): $115K–$125K total payback (1.15–1.25 cap)
- Ecommerce-friendly MCA (Credibly, Forward, National Funding): $128K–$140K total payback (1.28–1.40 factor)
The decision tree
Branch 1: How urgent is the capital?
If you need money in your account within 48 hours: MCA. Platform RBF reapprovals take 5–10 days even with an existing account; standalone RBF underwriting takes 3–7 days. MCAs fund next-day or same-day for clean applications.
If you can wait 5–10 business days: start with the cheapest option and work outward.
Branch 2: What channels do you sell on?
- Shopify-only: check Shopify Capital first. They offer up to 6–8 advances per year to qualifying merchants at cap rates that are hard to beat. Only go outside if Shopify caps you too low or has declined.
- Amazon-only: check Amazon Lending first (cap rates 1.05–1.12 for established FBA sellers). If not offered, outside MCAs against FBA payouts at 0.8x–1.0x multiple.
- Stripe-processed DTC (custom storefront): Stripe Capital offers should arrive in your dashboard. Outside MCAs available against Stripe deposits at 1.0x–1.3x multiple.
- Multi-channel (Shopify + Amazon + wholesale): standalone RBF (Wayflyer, Clearco) or outside MCA — both can underwrite blended revenue, platform RBF cannot.
Branch 3: How much do you need?
- Under 50% of monthly revenue: platform RBF almost always available and almost always cheapest
- 50–100% of monthly revenue: standalone RBF (Wayflyer, Clearco) or MCA, depending on speed and channel mix
- Over 100% of monthly revenue: outside MCA at 1.5x revenue multiple, but realistically: take less, or pursue asset-based lending against inventory if you have meaningful inventory on hand
Where platform RBF programs draw the line
Shopify Capital
Shopify Capital extends to merchants with at least 3–6 months of sales history and predictable revenue patterns. Caps generally 0.6x–1.0x of trailing 3-month average revenue. Repayment is via fixed percentage (10–20%) of daily sales until the advance is fully repaid. Strengths: lowest cost in market, no application friction, no credit check. Weaknesses: caps low relative to standalone options, declines without explanation, eligibility gates change frequently.
Stripe Capital
Stripe Capital uses similar mechanics — fixed fee, percentage of daily Stripe-processed revenue. Eligibility based on processing history; merchants typically need 6+ months on Stripe with stable volume. Effective cost competitive with Shopify Capital. Weakness: only repaid through Stripe revenue, so multi-processor merchants effectively segregate their cash flow.
Amazon Lending
Amazon Lending offers term loans (not RBF, technically) to FBA sellers based on platform performance. Repayment is via fixed deductions from FBA payouts. Eligibility entirely opaque — Amazon decides without disclosing criteria. When offered, the cost is among the cheapest available to ecommerce. When declined, there is no appeal process.
Square Capital
For ecommerce merchants processing via Square Online or Square POS (less common in pure ecommerce). Same mechanics as Stripe Capital — fixed fee, percentage of Square-processed revenue.
Where standalone RBF shines
Wayflyer, Clearco, Settle, and similar standalone RBF lenders serve the gap above platform caps and the multi-channel case. Typical 2026 profile:
- Minimum revenue: $20K–$50K/month, depending on lender
- Time in business: 6+ months
- Advance size: $10K–$5M, often used for inventory or marketing
- Effective cost: 1.10–1.25 total payback
- Revenue share: 5–15% of daily incoming sales
- Term: variable, typically 6–18 months
The standalone RBF lenders also tend to underwrite multi-channel revenue more intelligently than MCAs do, and they often offer inventory-purchase-specific structures (Settle and Wayflyer both let you draw against incoming purchase orders).
When outside MCA still wins for ecommerce
- Speed-critical capital needs. Inventory needs to ship Friday, vendor wants payment today, MCA can fund tomorrow. RBF cannot match that.
- Already maxed on platform RBF. Shopify Capital won't advance another $50K, Amazon Lending hasn't offered, and you need additional capital. Outside MCA fills the gap.
- Channel mix that platforms cannot price. Wholesale revenue + DTC + Amazon FBA + Etsy doesn't fit into Shopify Capital's model. Outside MCAs underwrite blended deposits.
- Need predictable daily outflow for cash modeling. Some merchants prefer the certainty of a fixed daily ACH over the variable RBF percentage. Rare, but legitimate.
The dual-product trap
The most expensive mistake we see: ecommerce merchants who take a platform RBF, then take an outside MCA on top, then take a standalone RBF on top of that. Each lender thinks they have a clean position. In reality, the merchant is paying three separate daily-or-percentage debits against the same revenue.
A $80K-revenue Shopify brand with a Shopify Capital balance at 15% revenue share, an outside MCA at $400/day, and a Wayflyer advance at 8% revenue share is hemorrhaging cash. The combined drag on daily revenue is approximately:
- Shopify Capital: 15% of revenue
- Wayflyer: 8% of revenue
- MCA: $400 fixed ÷ ~$3K daily avg = 13%
- Combined: 36% of every dollar gone to financing before COGS, fulfillment, or operations
That brand is 90–120 days from default. The fix is consolidation — one larger advance that pays off the smaller ones — not adding another product. Ask any funder about consolidation explicitly before signing.
What good documentation looks like for ecommerce
- Six months of business bank statements
- Shopify, Amazon Seller Central, and Stripe statements (last 6–12 months)
- Product-mix breakdown showing top SKUs and category margins
- Return rate and refund rate by month
- Customer acquisition cost (CAC) and contribution margin disclosure if asking for marketing-spend capital
- Inventory on hand and incoming PO schedule
Frequently asked questions
- Is revenue-based financing the same as an MCA?
- No. Both are structured as future-receivables purchases, but the repayment mechanism differs. A traditional MCA charges a fixed daily ACH amount regardless of revenue. RBF charges a fixed percentage of incoming revenue — typically 5–12% of daily Shopify or Amazon settlements — so when sales drop, your payment drops proportionally. RBF effective cost is usually 1.10–1.25 total payback (10–25% fee), MCAs run 1.28–1.45.
- Which is cheaper for an ecommerce business: MCA or RBF?
- RBF is almost always cheaper in absolute fee. A $100K RBF advance typically repays $115K–$125K total. The same $100K MCA repays $130K–$140K. The catch: RBF caps approvals lower (usually 60–80% of monthly revenue) and underwriting takes 2–5 business days instead of 24–48 hours. For high-revenue DTC brands that can wait, RBF wins. For sub-$50K monthly revenue or urgent capital needs, MCAs usually win.
- Will Shopify Capital count against my MCA eligibility?
- Yes. Shopify Capital advances function as RBF and show up in your bank statements as Shopify-deducted settlements (your daily payout drops by the financing percentage). MCA funders see this and either decline, reduce the advance amount, or stack at higher rates. The cleanest sequence is: use Shopify Capital first when available, only seek outside MCAs when Shopify caps your advance or declines.
- Can Amazon sellers use MCAs against FBA payouts?
- Yes, with caveats. Amazon FBA payouts hit your business bank account every 14 days (or daily for sellers in the Pay-by-Invoice program). MCA funders treat these as legitimate receivables and underwrite against them. The complication is Amazon reserves — Amazon holds 5–15% of revenue in reserve for returns and chargebacks, which funders discount when calculating advance amount. Expect a 0.8x–1.0x advance multiple on net Amazon revenue.
- What advance multiple should an ecommerce business expect?
- Traditional MCA: 1.0x–1.5x of monthly average deposits, depending on time in business and channel mix. RBF: 0.6x–1.0x of monthly revenue, with caps that grow as the relationship matures. A Shopify-only DTC brand doing $80K/month with 18 months of history typically gets offered $80K–$120K MCA or $50K–$80K RBF.
- How do return rates affect underwriting?
- Significantly. Funders pull or ask for your return rate from Shopify, Amazon, or processor data. Apparel and beauty DTC brands averaging 18–25% return rates get priced 3–6 points higher on the factor than electronics or supplements at 4–7% returns. RBF lenders are often more lenient because their percentage-of-revenue model self-adjusts when refunds reduce net deposits.
- Is Stripe Capital or Square Capital different from outside MCAs?
- Functionally similar but cheaper. Stripe Capital and Square Capital both function as RBF — they take a fixed percentage of your processor settlements until the advance is repaid. Effective cost typically 1.08–1.18 total payback (8–18% fee), which beats outside MCAs by 15–25 points on the factor. Always check your processor's capital offer before going to outside funders.
- When does outside MCA beat platform RBF for an ecommerce brand?
- Three cases. First, when platform RBF caps your advance below what you actually need (common above $250K). Second, when you sell across multiple platforms and need a single advance against blended revenue. Third, when speed matters — outside MCAs fund in 24–48 hours vs 5–10 days for Stripe Capital or Shopify Capital reapprovals. Otherwise, platform RBF is the cheaper default.
