Frequently asked questions
ChannelAdvisor (now rebranded as Rithum following its 2023 merger with CommerceHub) is a large US-based multichannel commerce platform primarily focused on marketplace management — Amazon, eBay, Walmart — as well as digital advertising feeds. It's an enterprise product with pricing to match, typically used by large retailers with complex multichannel operations.
ChannelAdvisor has UK operations but is US-centric in its pricing model, support structure, and marketplace focus. UK merchants often find it over-engineered for feed management needs (it's primarily a marketplace listing tool) and expensive relative to feed-only alternatives. Trajekt is built in the UK, priced in GBP, and focused purely on feed management and optimisation.
ChannelAdvisor/Rithum does not publish pricing publicly. Based on industry reports and reviews, it is positioned as an enterprise platform — check their website for a current quote. Trajekt's pricing is transparent: £0 free plan, £19 Starter, £49 Growth, £99 Pro. For merchants who need product feed management without the full ChannelAdvisor marketplace suite, Trajekt offers substantially better value.
No — and that's intentional. ChannelAdvisor is a full multichannel commerce platform covering marketplace listing management, order routing, inventory sync, and repricing. Trajekt focuses on product feed management and optimisation. If you need to manage Amazon Seller Central listings, fulfil orders from multiple marketplaces, or run repricing algorithms, ChannelAdvisor/Rithum is a more appropriate tool. If you need Google Shopping, ChatGPT, Meta, and Awin feeds optimised and automated, Trajekt is purpose-built for that use case — at transparent GBP pricing from £0/month.
ChannelAdvisor has not confirmed support for ChatGPT Shopping's JSONL/SFTP format. Trajekt generates OpenAI-compliant JSONL with correct variant handling and automated SFTP delivery — purpose-built for the format rather than retrofitted.
Yes. Trajekt connects directly to your Shopify, WooCommerce, Magento, or BigCommerce store and builds feeds from your source product data. There's nothing to migrate from ChannelAdvisor — Trajekt starts fresh from your live catalogue. You can run both in parallel during transition.
