B2B Onboard vs BSS Commerce
Two apps. Two different bets on Shopify stability.
BSS Commerce installs theme code and offers a styling service. B2B Onboard runs through Shopify App Proxy and ships zero Liquid changes. Here is where the two apps differ in practice, and where BSS is a better choice.

How B2B Onboard and BSS Commerce differ
Four workflow areas where the two apps make opposite choices.
Architecture: App Proxy vs theme injection
B2B Onboard renders forms through Shopify App Proxy. No Liquid edits, no theme app blocks, no script injection. Uninstall and the storefront is untouched. BSS Commerce installs theme app extensions and writes Liquid into the theme, so theme updates can break the form and removing BSS leaves residue behind.
Tax exemption at every tier
B2B Onboard hands approval to Shopify's native B2B Company model on Basic, Shopify, Advanced, and Plus. Tax exemption is part of the standard flow. BSS Commerce gates tax exemption features behind its highest pricing tier, which has produced low-star reviews from merchants who installed expecting the feature and only found it on the top plan.
EU and non-EU pricing reliability
BSS Commerce has documented breakage in EU and non-EU pricing on its platinum plan, with merchants reporting that pricing rules stopped applying after a Shopify update. B2B Onboard checks EU VAT numbers against VIES at submission time and stores the verification result. Pricing and tax stay inside Shopify's native B2B model, which is maintained by Shopify.
Self-serve setup vs human styling
BSS Commerce offers a styling service. Their team will style the registration form to match your theme. B2B Onboard ships a self-serve form builder with theme presets and import, but no human styles the form for you. The trade-off is honest: less hand-holding, faster control, and a five-minute setup instead of a back-and-forth ticket.
Where BSS Commerce is a good fit
BSS Commerce is a good fit for merchants who want a configured-for-you experience and are happy to pay a tier premium for human styling and a deep feature surface. If you would rather pay BSS to match your theme styling than do it yourself, BSS has a service B2B Onboard does not match structurally. The high-touch onboarding is a real strength, not a marketing claim.
B2B Onboard is the better choice when theme safety matters more than hand-holding, or when tax exemption is needed on a starter plan.
