From install to settled,
3 steps.

Stripe Connect handles the money. QUARVO handles the split. You handle the receipts.

01

Connect your store

Install the Shopify app, drop in the WooCommerce plugin, or call the Direct API. Stripe Connect handles auth in 5 minutes — zero changes to your existing checkout flow.

  • Shopify, WooCommerce, BigCommerce, Direct API
  • Your existing Stripe account remains source of truth
  • Drop-in checkout button or full programmatic control
02

Customer splits at checkout

When their card alone isn't enough, your customer picks "Split with QUARVO". They authorize each card via Plaid. We split the cart optimally across the credit they already own.

  • Customer never leaves your checkout
  • No new accounts, no new debt, no new credit pulls
  • They keep all their card rewards
03

You get paid in full

Stripe Connect routes a single payment to your account. QUARVO deducts 2% automatically — no invoices, no reconciliation. The decline became a sale.

  • Single Stripe charge — no reconciliation overhead
  • 2% auto-deducted via Stripe Connect, transparent line item
  • Failed splits cost you nothing

Watch a $2,400 sale

All animations represent actual production timing. Median wall-clock for a 2-card split is 0.85–0.95s end-to-end. Customer never sees a partial charge — if any auth fails, all are voided atomically before the error is shown.

Your Stripe. Your money.
We just orchestrate.

Quarvo never holds funds, never stores card data, never touches your checkout schema. We're a thin layer of math — the rails are Stripe.

Stripe Connect

Payments flow into your existing Stripe account. Quarvo never holds funds. Your payout schedule, your dashboard, your tax forms.

Zero card data stored

Card numbers never reach our servers. Authorization happens via Plaid + Stripe tokens. Your customer's PAN stays at the bank where it belongs.

PCI-DSS via Stripe

Compliance inherited from Stripe's Level 1 PCI-DSS certification. Quarvo's scope is reduced to orchestration only — no SAQ on you.

Zero checkout changes

Your existing flow stays exactly as it is. Quarvo appears as one extra option next to your current payment methods. Failed splits cost you nothing.

Questions, answered.

Mixed for merchants and shoppers. Email support@quarvo.io if yours isn't here.

For merchants
How long does setup take?
5 minutes for Shopify or WooCommerce (one-click install + Stripe Connect OAuth). 30 minutes for Direct API integration. Your existing checkout stays untouched — Quarvo appears as one extra payment option.
When and how does Quarvo's 2% get charged?
Auto-deducted via Stripe Connect when a customer completes a Quarvo split. You see it as a transparent line item on the same payout as the sale. No invoices, no monthly bill, no reconciliation. Failed splits cost you $0.
Will Quarvo touch my customers' card data?
No. Card numbers never reach our servers. Card authorization is handled by Plaid + Stripe tokens. PCI-DSS Level 1 compliance is inherited from Stripe; Quarvo's scope is reduced to orchestration only — no SAQ on you.
What if a split fails halfway?
Stripe Connect rolls back automatically. None of the cards get charged unless every leg succeeds. The customer sees a clear failure state and can retry with a different card combination. You never see a half-paid order.
For shoppers
How much does Quarvo cost me?
Nothing. The merchant covers Quarvo's 2% so the sale doesn't slip away. You pay exactly the cart total — split across the cards you already have.
Will this affect my credit score?
No hard pulls. No new inquiries. No new accounts. Quarvo uses your existing available credit through Plaid (read-only) — your credit profile stays exactly as it is.
Do my card rewards still apply?
Yes. Each card you split across is charged normally by its issuer, so you earn your usual cashback / points / miles. Quarvo just decides how much goes on each.
How is this different from Klarna / Affirm / BNPL?
BNPL lends you new credit and charges interest or fees. Quarvo activates credit you already own across your existing cards. No new debt, no new interest, no new accounts. Fundamentally different.

declined high-ticket sale.

Deep-dives for merchants on high-AOV decline recovery — the cohort, the math, the architecture, and the playbook.

The science behind Quarvo

More buying power.
Same wallet.

In quantum physics, a quark is the most fundamental particle in the universe. It cannot be divided further. But its real power is not in its size — it's in how it combines with other particles to form something much larger.

Three quarks united form a proton. Only through combination does power exist.

That's exactly what Quarvo does.

"Quarvo is to credit cards what quantum physics is to particles — unlocking massive power from what already exists."
