Why outstaff for BigCommerce Checkout SDK?
Direct hiring locks you into long recruitment cycles, fixed payroll, and compliance headaches. Outstaffing lets you plug vetted JavaScript specialists straight into your sprints, keeping IP secure while avoiding HR overhead. Scale squads up or down in days, not months, paying only for the capacity you need. With our augmentation model, you stay in full product control, while we shoulder sourcing, vetting, equipment, benefits, and local tax compliance.

What CTOs Say
“In 72 hours we had a TypeScript guru integrating the BigCommerce Checkout SDK. The Smartbrain.io engineer refactored our React components, implemented async/await payment logic, and cut cart-to-cash time by 18 %. Onboarding felt like adding an internal dev—no delays, no HR paperwork.”
Daniel Foster
CTO
GearFlow Logistics
“Our Magento sunset meant fast migration. Smartbrain.io delivered a senior Node.js developer who wrote custom Checkout SDK plugins, configured webpack, and finished QA two sprints early. Productivity jumped 32 % while my core team stayed focused on micro-services.”
Maria Sanders
Head of Engineering
PeakOutdoor Retail
“Smartbrain’s React-Redux specialist implemented one-page checkout, leveraging ES6 modules and the BigCommerce Checkout SDK hooks. A/B tests show 15 % higher conversion. Flexible month-to-month contract meant zero risk as peak season ended.”
Leonard Kim
Product Manager
FreshBite Foods
“Our fintech app required strict PCI DSS. The augmented JavaScript lead from Smartbrain rewrote payment flows with the BigCommerce Checkout SDK, added Jest tests, and passed audit in one attempt. Time-to-compliance cut by 40 %.”
Samantha Blake
Compliance VP
CrediSure Capital
“We run 12 storefronts. Smartbrain.io provided a Vue.js engineer who modularized the Checkout SDK integration, shared code via npm packages, and enabled locale switching. Deployment scripts with CI/CD shaved off releases from weekly to daily builds.”
Andre Wilson
Dev Team Lead
BrightHome Decor
“Our legacy jQuery checkout crashed under load. Smartbrain’s specialist introduced modern ES2022 patterns, lazy-loaded SDK widgets, and reduced bundle size by 28 kB. Cart abandonment dropped 11 % in the first month.”

Industries We Empower
Retail & D2C
Retailers rely on JavaScript-driven BigCommerce Checkout SDK integrations to craft one-click purchases, dynamic promos, and real-time tax calculation. Augmented developers optimize bundle size, implement Apple Pay, and A/B-test UX—helping stores boost conversion while freeing in-house teams for merchandising.
FinTech
PCI-compliant checkout flows for digital wallets, BNPL, and tokenization demand deep SDK knowledge. Outstaffed JavaScript experts harden encryption, add 3-D Secure, and fine-tune fraud rules—accelerating launches without risking security.
Subscription SaaS
Recurring billing, prorated upgrades, and metered usage require custom BigCommerce Checkout SDK hooks. Augmented engineers build billing micro-frontends, webhook listeners, and analytics dashboards to slash churn and streamline onboarding.
Automotive Parts
High-SKU catalogs need VIN lookup, complex shipping matrices, and B2B pricing. JavaScript specialists extend the Checkout SDK for tiered accounts, multi-address orders, and ERP sync—delivering frictionless procurement for dealers.
Healthcare eCom
HIPAA-aware carts, prescription validation, and cold-chain shipping rules complicate checkout. Outstaffed JS pros embed secure tokenization, age-gate modals, and realtime inventory APIs, keeping compliance intact.
Travel & Ticketing
Dynamic seat maps and date pickers stress vanilla carts. Developers augment the Checkout SDK with React portals, caching layers, and custom payment gateways to ensure sub-second booking experiences at peak traffic.
Wholesale B2B
B2B portals need purchase-order flows, credit limits, and negotiated price lists. JavaScript experts refactor checkout to support account-based pricing and quick-reorder capabilities through the BigCommerce SDK.
Media & Publishing
Paywall variations, bundle offers, and international VAT essentials are addressed by custom Checkout SDK scripts, Stripe integration, and geo-pricing algorithms written by augmented developers.
Non-Profit
Donation checkouts differ from retail. Outstaffed JS engineers tailor the SDK for recurring gifts, tax-deductible receipts, and multi-currency donations, improving donor experience without raising operational cost.
