Round-Up API is checkout giving, rebuilt as infrastructure. The only round-up platform where the donation is never touched — your fee is billed to you, the merchant, not skimmed from the gift.

01 The problem
The demand is proven. The tools quietly take a cut of it.
Shoppers want to give at checkout, and merchants want to offer it. But the popular Shopify plugins charge 10–13% taken directly from the donation — so the charity receives less than the customer intended, and the merchant is locked into a single charity network with no infrastructure underneath. It works, but it skims the gift, and that's a trust problem hiding in plain sight.

The customer gave $1. The charity got $1. Your fee is billed to you.
02 Our approach
Round-ups, rebuilt as financial infrastructure.
The plugins are products. Round-Up API is the layer beneath them — the same hardened pipeline any checkout can embed, without building payments, idempotency, and reconciliation from scratch. We made one decision differently from everyone else: the fee comes from the merchant, never the donation.
💯
The charity keeps everything
Your platform fee is billed to you and settled separately. Every cent a customer rounds up arrives at the cause — on every tier, with no exceptions.
🔌
Runs on any checkout
Shopify Plus, WooCommerce, custom checkouts and POS. Platform-agnostic infrastructure rather than a plugin tied to one ecosystem.
📒
Provable, to the cent
Settlement-first execution and a tamper-evident ledger mean money collected always equals money disbursed — and you can audit every movement.
03 See it live
Touch the actual experience
This is what your customers and your team would see. Flip the round-up toggle in the checkout, then switch to the merchant dashboard.
What's happening here
1
The order rounds $23.40 up to $24.00. The spare 60¢ is the donation — never a percentage, never a guess.
2
The shopper stays in control. The toggle is off by default until they opt in — try it.
3
The reassurance line is the whole pitch: 100% reaches the charity. Your fee is billed to you, never skimmed from the gift.
4
The total updates transparently, showing exactly what was added. No surprises on the receipt.

Every figure ties back to the ledger. Collected = Disbursed + Pending, always — that's the product.
Bring your own causes

04 Why it's trustworthy
Built like financial infrastructure, because it is.
A giving product lives and dies on trust. Underneath the simple checkout prompt is a pipeline engineered so money is never lost, double-counted, or sent on a payment that later reverses.
⛓️
Settlement-first execution
A round-up only commits once the underlying payment confirms settlement — never on a reversed or abandoned order.
🔁
Idempotent by design
Every event is fingerprinted, so duplicate webhooks or retries can never double-charge a customer or double-send a donation.
📖
Double-entry audit ledger
Every movement is recorded as two equal, opposite postings — append-only and tamper-evident, so the books always balance.
🏦
Verified disbursement
Funds reach charities through a Donor-Advised Fund, so merchants carry no charitable registration or compliance burden.
05 The roadmap
Charity is the wedge. The pipeline is the platform.
The same engine that routes a round-up to a charity can route it anywhere. Charity giving lets us start in a low-regulatory environment while we harden the infrastructure — then open it to the destinations merchants ask for next.
NOW
Charity giving
Round-ups to vetted charities, with 100% reaching the cause. The trust-first entry point.
NEXT
Loyalty points
Route spare change into a merchant's own rewards ledger — deepening retention, not just goodwill.
LATER
Carbon offsets
Convert round-ups into verified offsets from certified registries, with the same reconciliation guarantees.
VISION
Micro-savings
Per-customer savings wallets — the highest-value destination, approached deliberately with the right licensing.
Be part of the founding pilot.
We're inviting a small group of merchants to run Round-Up API on real checkouts before public launch. Development install, no App Store review, full flow end to end. Fill in a few details and we'll be in touch.

Takes about a minute. The more you tell us, the faster we can confirm fit for the pilot.
