Your business evolves. The website you built two years ago may need new features today: an online booking system, a pricing calculator, a customer portal, an API integration with a new tool, a gated content area for members. Building these features onto your existing website — rather than rebuilding the whole site — is almost always faster and more cost-effective. We specialize in adding targeted, well-built features to existing sites across all major platforms.
nnBooking and Scheduling Systems
nOnline booking is one of the highest-conversion features any service business can add. When customers can book instantly without calling, conversion rates typically increase 35–50% and the quality of leads improves — someone who books themselves is far more committed than someone who submitted a form. We build custom booking systems with service selection, staff/location assignment, calendar integration (Google Calendar, Outlook), automated reminders, deposit collection and no-show management. Native booking systems outperform third-party widgets because they're fully branded and don't redirect users away from your site.
nnCalculators and Interactive Tools
nInteractive calculators are among the highest-performing content assets for lead generation and SEO. A mortgage calculator, insurance quote tool, ROI estimator, shipping cost calculator or product configurator provides immediate value to visitors and captures qualified leads in exchange. We build pixel-perfect calculators with complex logic, conditional fields, instant results and lead capture at the point of maximum engagement — when the visitor has just seen a compelling result.
nnMember Areas and Gated Content
nMembership and subscription features — gated content, member-only pricing, course delivery, community platforms — require careful implementation to work securely and reliably. We build member areas with registration flows, subscription management (integrated with Stripe), content access control, member dashboards and automated email sequences for onboarding and retention. These features can transform a content website into a recurring revenue business.
nnPayment Integration
nAdding payment processing to a website requires both technical expertise and security knowledge. We implement payment flows using Stripe, PayPal, Square and other processors with proper security practices: no sensitive card data touching your server (tokenization), PCI-DSS compliance, fraud prevention and proper error handling for declined payments. We build straightforward product purchases, subscription billing, split payments and marketplace payment flows.
nnThird-Party API Integrations
nModern businesses use dozens of software tools — CRM, accounting, shipping, marketing automation, analytics. Connecting these systems via API eliminates manual data re-entry and creates workflows that run automatically. We build API integrations with virtually any platform that has an API: Salesforce, HubSpot, QuickBooks, Xero, ShipStation, Zapier custom webhooks and custom-built API connectors.
Frequently Asked Questions
We work with WordPress, Shopify, Wix, Squarespace (where the platform allows), custom PHP and most modern web applications. Some platforms (like Wix) have limitations on what custom features can be added.
We provide a fixed-price quote after a 30-minute scoping call to understand requirements. No surprises — the price we quote is the price you pay.
Not if done correctly. We ensure new features are efficiently coded, use appropriate caching and don't add unnecessary third-party script weight.
We test everything in a staging environment before deploying to production. All our feature work is peer-reviewed and includes regression testing of existing site functionality.
Features delivered with documentation. Ongoing maintenance is available via our monthly administration retainer.
