B2B · Wholesale · FleetThe tools are free. The platform behind them runs the whole business.
Every tool here is built on sparx. One platform for your site, your content and, when you sell, your orders. Turn on the parts you need and leave the rest off.
One platform, not twelve tabs
Your site, content, CRM, email, commerce, and B2B live in one place. One login, one bill. Stop renting a dozen disconnected tools and paying someone to wire them together.
One source of truth
Every module sits on the same data. A customer, a page, an order, a campaign. One record, read everywhere. No sync jobs, no Zapier, no version that disagrees with the other version.
Pay only for what you switch on
Modules turn on independently. Run CMS on its own, CRM on its own, or the full stack. All of it first-class. No tiers, no seat minimums, no paying for capability you never touch.
API-first and AI-native
Every feature is an API, and a built-in MCP server lets Claude, ChatGPT, or Copilot read and write your live business data in plain English. Ask for it; it's done. The dashboard is just one way in.
The same people built the rest of it.
These handle one job each, free, forever. sparx is the whole thing (site, store, content, customers, email) switched on a module at a time, on one bill.
