Why Arceto

Built for catalog sellers, not for marketing departments

If you have a price list, an inventory file, or an ERP feed, you have everything you need to start selling on Arceto today.

AI-assisted onboarding

Drop your distributor or ERP file once. Our AI reads the headers, samples the data, and proposes a column-by-column map. You confirm — that's it.

Always-fresh prices & stock

Schedule a refresh every hour, every day, or trigger it on file change. Stale stock turns into refunds — we won't let that happen.

Publish everywhere

One Arceto feed pushes your catalog to Arceto.com, and we can also push the same SKUs to Amazon, Walmart, Newegg and eBay on your behalf.

Feed Sync

Your distributor's CSV. Our marketplace. Reconciled automatically.

Most catalog sellers already get a daily inventory file from their distributors. The hard part has always been getting that file into a marketplace's exact column format. Feed Sync handles that translation for you.

  • AI reads your column headers and proposes a map — typically 90%+ accuracy on first read
  • Schedule daily, hourly, or on-demand refreshes
  • FTP, SFTP, HTTPS, or manual upload — your choice
  • Failed runs are explained in plain English by email
  • Full run history with what changed, what skipped, what failed

FAQ

Common questions

What does it cost to sell on Arceto?
There are no upfront listing fees and no monthly minimum. We take a per-order commission on items that sell, and you keep the rest. Final commission rates are confirmed at signup based on your category mix.
What kinds of sellers does Arceto work with?
Arceto is built for catalog sellers — distributors, value-added resellers, manufacturers selling direct, and brands with predictable inventory feeds. If you can produce a price/stock file or talk to a REST API, you're a fit.
Do I have to ship from my own warehouse?
Yes — Arceto is currently a marketplace-of-record for the order, and the seller fulfills. You set your shipping rates and methods, and we route the order to your fulfillment system.
How fast is onboarding?
Most sellers can finish the six onboarding steps in under an hour: sign up, payment card on file, shipping settings, return address, data feed connection, seller profile, and W-9 form. Your dashboard shows you exactly what's left at each step.
Can I sell on Arceto and other marketplaces at the same time?
Yes — and you should. Arceto can also republish your catalog to Amazon, Walmart, Newegg, and eBay using the same feed. Per-tenant settings let you set different prices, hold-back inventory buffers, or block specific channels per SKU.
What happens if my distributor's file format changes?
Feed Sync will flag the run as failed and email you a plain-English explanation of what changed. You can re-run the AI column mapping in a couple of clicks — no developer required.
Is the W-9 form required?
Yes — US tax law requires us to have a W-9 on file for any seller before we can pay out earnings. Our W-9 form is fully digital and takes about 2 minutes.
