Sell, ship, get paid.

Commerce is the transactional core of sparx — products and inventory, a checkout that converts, Stripe payments, and order operations that hold up at real volume. Run it headless on the API, or pair it with Builder for a hosted storefront. One order object, cart to fulfilled.

One order, catalog to fulfilled.

Every order travels the same path on one database — no webhooks trading state at 3am, no sync to drift. Stock, pricing, and customer history are all re-checked as it moves.

01 · catalog

Added to cart

Products, variants, and collections — the matrix of color, size, and SKU. Price and stock are read live, never cached stale.

02 · cart

Validated

Inventory re-checked, discounts re-validated, B2B account pricing applied. Abandoned carts fire an email automation.

03 · checkout

Paid

Single-page checkout, live tax and shipping, a Stripe payment intent confirmed on submit. Inventory decrements atomically.

04 · fulfillment

Shipped

Pick, pack, add tracking — partial shipments allowed. Tracking triggers the shipping email; refunds restock and return via Stripe.

A checkout built to convert.

One page, not a five-screen funnel. Address autocomplete, saved payment methods, and the wallets your customers already use — all wired in, all conversion-tuned out of the box.

A

Address autocomplete

Suggestions as they type — fewer failed deliveries, fewer typos, faster fills.

B

Wallets & one-click

Apple Pay, Google Pay, and Link — Stripe’s one-click checkout — for buyers in a hurry.

C

Saved payment methods

Returning customers skip the card form entirely. 3D Secure and SCA handled automatically.

D

Live tax & shipping

TaxJar or Avalara for tax; carrier rates via EasyPost. Totals update before they pay.

Stripe, plus the wallets they already use.

Payments run on Stripe as the primary processor — you keep your own Stripe account and relationship. sparx connects it through Stripe Connect; the methods below are on by default.

CardsEvery major card, 3D Secure and SCA handled automatically.
Apple PayOne-tap on iPhone and Safari — no card entry, higher conversion.
Google PayThe same one-tap path for Android and Chrome shoppers.
LinkStripe’s one-click checkout — saved details across every Stripe store.

Test mode runs against staging, payment intents confirm on submit, and refunds return to the original method. Need net terms or a PO at checkout instead? That’s B2B, layered on the same engine.

A transaction fee that shrinks as you grow.

One honest line, no asterisks. sparx takes a small per-transaction fee on Commerce — and it steps down the more of the platform you run, all the way to nothing.

Commerce only0.5%

The base rate, per transaction, on top of your own Stripe processing. That’s the whole sparx fee.

With CRM0.3%

Add CRM and the per-transaction fee drops — the more of the spine you use, the less each order costs you.

At $299+ / mo of modules0%

Once your active modules total $299 a month or more, the per-transaction fee disappears entirely.

The fee is taken through Stripe Connect and is separate from Stripe’s own processing rate. No per-seat charges, no per-product metering — see full pricing.

Everything after “paid”.

The order is only the start. Commerce ships the operations that make selling sustainable at real volume — inventory, promotions, refunds, reporting, and bulk tooling.

Inventory that tracks

Per-variant counts, deny or backorder policy, low-stock thresholds that publish alerts. Bulk-adjust by CSV or API.

Discounts & promotions

Percentage, fixed amount, free shipping, buy-X-get-Y. Code or automatic, with minimums, date windows, and usage limits.

Refunds & returns

Full or partial, back to the original method via Stripe. Inventory restocks on refund, with the reason recorded for reporting.

Order timeline

Placed, paid, noted, fulfilled, tracked, refunded — every event in order, with staff notes and customer-visible notes.

Reports that matter

Revenue by period, top products and customers, AOV trend, inventory valuation, and the sessions-to-purchase funnel.

Built for real volume

Multi-fulfillment partial shipments, bulk order operations, and full CSV exports — order ops that scale with shipping.

Headless, hosted, or both.

Commerce is the engine, not the front end. Drive it entirely through the API and MCP, or switch on Builder and get a hosted storefront on your own domain — same data either way.

commerce + your stack

Run it headless

Every capability is an API endpoint first; the dashboard is one consumer among many. Build your own front end, or let an AI assistant work the catalog and orders over MCP.

  • Full REST + GraphQL surface — catalog, cart, checkout, orders.
  • SSR-ready with CDN caching for sub-200ms TTFB.
  • Read and write live commerce data from Claude, ChatGPT, or Copilot.

commerce + builder

Get a hosted storefront

Pair Commerce with Builder and the storefront renders for you — product pages, collections, cart, and the converting checkout — on your custom domain, SSL and CDN handled.

  • Product, collection, cart, and account pages out of the box.
  • Full-text product search with filters and sort.
  • Your theme and brand — selling shares one design system with the rest of the site.
Commerce + Builder

See the whole funnel, on the same data.

Because orders, customers, and content share one database, the numbers reconcile by default — no exports, no two systems disagreeing about what happened.
