Questions & answers

How fast can I connect OnBuy.com to Sendcloud?

Setup takes minutes. In OnBuy.com, install the OnBuy.com connector for Sendcloud and authorize your account, and orders start syncing into Sendcloud. Your OnBuy integration is live as soon as the first label prints.

For step-by-step instructions, see Sendcloud's OnBuy.com Help Center article.

What does the OnBuy integration include?

Once connected, Sendcloud automates the shipping work and writes results back.

  • Automatic order import from OnBuy.com

  • Bulk label creation in Sendcloud

  • 170+ carriers with own-contract or Sendcloud rates

  • Pack & Go for picking and packing

  • Track & trace with status flowing back to OnBuy.com

  • Multi-channel processing alongside your other stores

  • OnBuy seller stays flexible as you scale orders

How does the OnBuy shipping integration handle marketplace shipping rules?

OnBuy.com marketplace rules stay in force. Sendcloud lets me pick how to ship, per order: own contracts, Sendcloud rates, or any marketplace-specific labels supported by the channel.

  • Per-order choice: Mix shipping options inside the same order list.

  • Status sync: Tracking flows back so the marketplace sees fulfilled orders.

The OnBuy marketplace fits how OnBuy.com sellers actually run shipping.

How much does the OnBuy integration cost, and can I cancel?

Start on the Sendcloud Free plan with Sendcloud rates; you only pay per label once you ship. Use-your-own-contract setups need a paid Sendcloud plan.

Disconnect your OnBuy.com Sendcloud connection anytime from Settings > Integrations. No contract, no exit fees. See Sendcloud plans and pricing.

Can I keep my own carrier contracts?

Yes. Use Sendcloud's pre-negotiated rates, upload your own carrier contracts, or mix both. Add or switch carriers anytime across 170+ options. Own-contract setups need a paid Sendcloud plan.

Where does the OnBuy.com integration work?

OnBuy is a UK-only marketplace, so most shipments are domestic. For any cross-border parcels you ship outside the UK on your own carrier contracts, Sendcloud generates customs documents (HS codes, weights, values) automatically.

How are tracking and customer communication handled for OnBuy orders?

Tracking flows back to OnBuy for buyer communications. You see track & trace in your Sendcloud account for operational visibility. For other channels, you can use Sendcloud's branded tracking pages and messages.
