Camila Built Una Vida Botanicals on Shopify. Four Years In, the Math Stopped Working.

Camila Built Una Vida Botanicals on Shopify. Four Years In, the Math Stopped Working.

Camila Reyes founded Una Vida Botanicals out of her Denver kitchen in 2022 — clean-ingredient skincare for women in their 30s, sold direct-to-consumer on Shopify. Last year she crossed $28,000 a month in revenue. About 390 orders, average order value around $72.

She came to a Shopify Payments vs merchant account question the way most DTC founders do: she added up what she was paying. On the Basic plan at $39 a month, every online sale ran 2.9% + $0.30 through Shopify Payments. That worked out to roughly $929 a month in processing fees. Over a year, $11,148.

She wasn’t shopping for a complaint. Shopify Payments worked. The deposits hit on schedule, the chargebacks got handled, the dashboard told her what she needed to know. The question was simpler than that: was she paying more than she had to?

She started reading. She found posts comparing Shopify Payments to Stripe — but Shopify Payments is built on Stripe, so the comparison didn’t really say much. She found posts comparing Shopify to Square, but she wasn’t trying to leave Shopify, just the bundled processor inside it. What she actually wanted was a Shopify Payments vs merchant account comparison: keep the storefront, replace the rail underneath.

That’s the post she couldn’t find. So this is the one I wrote her.

What Shopify Payments Actually Is (and Why It Isn’t a Merchant Account)

Shopify Payments is the payment processor Shopify built into the platform. When a customer buys something on a Shopify store and the store has Shopify Payments turned on, that transaction runs through infrastructure Shopify owns the merchant relationship for — but doesn’t actually own end-to-end. Under the hood, Shopify Payments runs on Stripe Connect. Shopify is the payment facilitator (the payfac); Stripe is the underlying processor; the acquiring bank is whichever one Stripe routes through.

That’s the setup that makes the Shopify Payments vs merchant account distinction matter. A real merchant account is a contract between the merchant and an acquiring bank, set up through a processor or ISO that knows the merchant’s business. The merchant has their own MID — their merchant ID number — which means their underwriting, their pricing, and their funding terms are negotiated for their volume and their card mix specifically.

With a payfac like Shopify Payments, the merchant is operating under Shopify’s master MID. The pricing is whatever Shopify decides to publish. The underwriting is automated. There’s no negotiation, because there’s no relationship — Shopify is just letting the merchant use their rail.

That’s not a complaint about Shopify Payments — it’s a description of how every payfac works. Stripe, PayPal, Square, Shopify Payments: all four use the same architecture. They’re built for fast onboarding and predictable pricing, not for cost optimization. The Shopify Payments vs merchant account question is really the payfac vs merchant account question, applied to whichever platform a given merchant happens to be on.

What Shopify Payments Actually Costs in 2026

Shopify renamed the middle plan from “Shopify” to “Grow” earlier in 2026. The four plan tiers and their Shopify Payments rates for online (card-not-present) transactions, per Shopify’s published pricing, are:

Those rates are flat. That’s the headline feature: predictable cost. Whether the customer pays with a basic Visa rewards card or a premium Amex business card, Camila pays the same 2.9% + $0.30 on Shopify Basic. The processing math is easy. The bookkeeping is easy. There’s no statement to decode.

What flat-rate pricing hides is that the underlying interchange — the wholesale rate set by Visa, Mastercard, Discover and Amex — varies dramatically by card type. A regulated debit card (under the Federal Reserve’s Regulation II cap) runs about 0.05% + $0.21. A standard Visa consumer credit card on a CNP transaction is around 1.80% + $0.10. A premium rewards card is closer to 2.10% + $0.10. An Amex card is its own conversation entirely.

Shopify Payments charges 2.9% + $0.30 on all of them. That’s the trade. On the cheap interchange cards, Shopify keeps the spread. On the expensive interchange cards, the spread is smaller. Across a typical DTC card mix, Shopify’s blended margin is meaningful — and that margin is the room a real merchant account on interchange-plus pricing can give back to the merchant.

The Third-Party Transaction Fee — the Mechanic Most Posts Skip

Here’s the part that turns the Shopify Payments vs merchant account question into something other than a free choice. If a Shopify merchant uses any payment processor that isn’t Shopify Payments, Shopify charges an additional transaction fee on every sale. The fee is on top of whatever the third-party processor charges. The tiers in 2026:

The fee exists because Shopify wants merchants to use Shopify Payments. The structure is honest about that — it’s a published rate, listed on Shopify’s pricing page, not a hidden charge. But it changes the Shopify Payments vs merchant account math fundamentally. A merchant on Basic who finds a real merchant account at, say, 2.4% effective doesn’t actually save 0.5% — they save 0.5% and then give back 2.0% to Shopify. Net: they pay more.

That’s the lock-in. And on Basic specifically, it’s almost insurmountable for a merchant whose only goal is reducing the headline rate. A 2.0% surcharge erases the savings any reasonable interchange-plus quote can produce.

The math changes — meaningfully — at Grow and Advanced. At Grow, the surcharge drops to 1.0%. At Advanced, it drops to 0.6%. At Plus, it’s effectively trivial at 0.2%. The Shopify Payments vs merchant account decision isn’t a single decision; it’s a decision that gets re-asked at every plan upgrade, because the lock-in lever loses force as the plan tier rises.

Running the Shopify Payments vs Merchant Account Numbers on Camila’s Volume

Camila’s situation, exactly: $28,000 a month in online card revenue on Shopify Basic, AOV $72, roughly 390 transactions a month. Card mix typical for clean skincare DTC — call it 80% consumer credit (Visa/MC/Discover at blended 1.95% + $0.10 interchange CNP), 12% rewards/premium credit at around 2.20%, 8% Amex at OptBlue rates closer to 2.50%. Effective wholesale interchange on her mix: about 2.04%.

On Basic, the math doesn’t work. Switching to a merchant account on interchange-plus would cost Camila roughly $325–$381 more per month — entirely because of Shopify’s third-party transaction fee. That’s the answer for any merchant on Basic asking the Shopify Payments vs merchant account question: stay on Shopify Payments. The lock-in lever does what it’s designed to do.

But Camila isn’t going to be on Basic for much longer. Her revenue is climbing about 12% month-over-month. By the time she crosses $42,000–$48,000 a month, the Grow plan starts to make sense regardless of the processor question — for the staff accounts, the better reporting, the lower Shopify Payments rate, the lower third-party surcharge. And at that point, the math changes.

Even at Grow, the math still favors Shopify Payments — by about $181–$281 a month. The 1.0% surcharge is smaller than the Basic surcharge, but it’s still larger than the interchange-plus margin saving on Camila’s specific card mix. The Shopify Payments vs merchant account answer at Grow is: usually still Shopify Payments, but the gap is narrowing fast.

Where Shopify Payments vs Merchant Account Actually Flips

The honest answer to where the Shopify Payments vs merchant account decision flips for a DTC store like Una Vida Botanicals: at the Advanced plan, on enough volume. Specifically, somewhere north of $100,000 a month in card revenue, on the Advanced plan ($399/mo, 0.6% third-party surcharge), with a card mix that includes meaningful B2B / premium-rewards interchange (closer to 2.15–2.35% wholesale).

At those numbers, a real merchant account on interchange-plus with a tight processor margin starts beating Shopify Payments by enough to clear the $399/mo plan upgrade and the 0.6% surcharge. The savings aren’t dramatic — typically $150–$400 a month for a $100K store — but they’re real, and they compound annually.

For Plus merchants, the math is essentially always in favor of a real merchant account at any volume above $1M annual. The third-party surcharge at 0.2% is so small that almost any reasonably-priced interchange-plus contract beats Shopify Payments on net. That’s why the Shopify Plus merchant account conversation is genuinely table-stakes in the enterprise DTC space — and why Plus merchants negotiate processing rates as a normal cost-management exercise, while Basic and Grow merchants generally shouldn’t bother.

What I Told Camila

The answer to her Shopify Payments vs merchant account question, as of $28K/mo on Basic: stay on Shopify Payments. Don’t switch. The 2.0% third-party surcharge is too high; no reasonable interchange-plus quote on her card mix beats it.

What I told her to actually focus on, instead of a processor change: the Grow upgrade, when it makes sense for the platform features. Plan at $105/mo, processing at 2.7% + $0.30. The math gets better. And then, when she crosses into the high-five-figure or low-six-figure monthly range — and especially if Una Vida Botanicals starts wholesaling to spas or doing B2B accounts — re-ask the question.

The answer at Advanced, on $120K/mo of mixed CNP/B2B card volume, is genuinely a real merchant account on interchange-plus. The answer at Plus, almost always. The answer at Basic or Grow on consumer DTC volume, almost never.

The thing I want every DTC founder reading this to leave with: “Shopify Payments vs merchant account” isn’t a one-time decision. It’s a question that should get re-asked at every Shopify plan transition and at every meaningful jump in monthly volume. The right answer changes with the merchant.

Camila’s running the question again in November, when she expects to clear $50K/mo. That’s the right way to do this. Not as a complaint about Shopify Payments. As ongoing cost management on a fast-growing business.
