What we engineer

Six capabilities under custom apps & integrations.

SaaS frontends

Next.js with auth, dashboards, billing, settings, team management. The boring engineering that decides whether users renew.

Internal tools

React + Node.js applications for ops teams. Order management, inventory routing, custom reporting. Often replaces $500/month worth of duct-taped SaaS.

Custom Shopify apps

Merchant-specific apps not on the App Store. Polaris UI, App Bridge, webhooks. $15K–$50K typical.

API integrations

Klaviyo, Mailchimp, Stripe, Plaid, Twilio, HubSpot, Salesforce, Xero, QuickBooks. Connect the systems that already exist.

WhatsApp Business integration

We've built three. WhatsApp Cloud API, message templates, business profile, customer-facing chatbots.

Click funnels

Custom funnel builds when GoHighLevel or ClickFunnels won't bend the way you need. From sales to upsell to downsell to success page.

FAQs

Common questions about custom apps & integrations.

Do you build custom Shopify apps or use public ones?

Both. We recommend public apps when they cover 80% of the need. Custom when they don't — internal tools, merchant-specific automation, or anything you don't want to share data with a third party for.

What's your custom web app cost range?

Simple integrations: $5K–$15K. Mid-complexity apps with admin UI and persistent data: $15K–$50K. Full internal systems with multi-role auth: $50K–$150K+.

Do you do React Native or mobile apps?

No. We focus on web. We will recommend a mobile partner if mobile is critical to your build.

Can you maintain the app after launch?

Yes — most clients move to a retainer (10–40 hours/month) for ongoing feature work, bug fixes, and integration updates.
