The right apps for your store — and nothing extra.
The BigCommerce App Marketplace has 1,000+ apps. Most stores need fewer than ten. We help you pick the ones worth paying for — and build custom plugins for everything the marketplace doesn't cover.
Search & Merchandising Apps
Searchspring, Klevu, and Searchanise — faceted search, AI-powered recommendations, and merchandising controls that BigCommerce's native search can't match at scale.
- Searchspring
- Klevu
- Searchanise
- Faceted search
Tax & Compliance Apps
Avalara AvaTax for real-time tax calculation, plus our custom Avalara CertCapture integration for B2B resale certificate management — the piece the off-the-shelf app doesn't cover.
- Avalara AvaTax
- CertCapture (custom)
- TaxJar
- Compliance audit
Shipping & Fulfillment Apps
ShipperHQ for advanced rate shopping, EasyPost for carrier integrations, and custom LTL freight quoting for B2B stores with large, heavy, or pallet-ship orders.
- ShipperHQ
- EasyPost
- Custom LTL
- Rate shopping
Reviews & Social Proof Apps
Yotpo, Okendo, and Judge.me — review collection, UGC, Q&A, and loyalty programs. We also wire up the review schema so Google and AI engines see your ratings in results.
- Yotpo
- Okendo
- Judge.me
- Review schema
Email, SMS & CRM Apps
Klaviyo, Attentive, and HubSpot connections — BC event data flowing into your marketing stack, customer segments built from order history, and flows triggered by BC checkout events.
- Klaviyo
- Attentive
- HubSpot
- Segment
Custom Plugins
When the marketplace doesn't have what you need, we build a custom BC app. Scoped, quoted, and delivered as a standalone plugin with documentation and an optional care plan.
- BC App SDK
- Custom OAuth
- Storefront widgets
- Admin apps
Frequently asked questions
How do you decide which apps to recommend?
We evaluate apps on: BC API integration quality, performance impact on Stencil pages, update cadence, and support reputation. We have hands-on experience with the apps we recommend and will tell you when a custom build is a better investment.
Do additional apps slow down our BigCommerce store?
Third-party scripts loaded in the storefront are the single biggest cause of CWV degradation on BC stores. We audit script load order, defer non-critical scripts, and set performance budgets so new apps don't kill your Lighthouse score.
Can you build a custom BigCommerce app that connects to our internal tools?
Yes. Custom apps using the BC App SDK with OAuth, storefront widgets, and admin panel extensions are a core part of what we build. Timeline is typically 3–6 weeks depending on scope.
