White-Label, Custom Web Development

Custom functionality is where client requests outgrow agency staffing. Backline’s developers have shipped over 1,000 WordPress sites and more than a decade of custom builds: custom plugins, third-party integrations, Advanced Custom Fields architectures, SSO logins, interactive maps, and features clients assumed weren’t possible. Your agency takes the request. We write the code. The client only ever sees your name on it.

We Take the Projects Other Devs Hand Back

Advanced WooCommerce builds, custom forms and workflows, third-party API integrations, membership systems, multilingual sites. Instead of duct-taping off-the-shelf plugins together, we build the functionality your client’s site actually needs, in whatever stack the site already runs. Our solutions have been good enough that clients have patented them.

Builder Agnostic, On Purpose

Every agency inherits a mixed portfolio: one client on Elementor, another on Divi, a third on Beaver Builder, a fourth on something the last developer swore by. We work in all of them, plus Gutenberg, Bricks, and the rest, with Advanced Custom Fields underneath when the build calls for structured content. We don’t migrate your clients to our preferred stack to make our lives easier. We make their current stack work.

That matters for white-label: your client’s site stays editable, familiar, and yours to manage, no matter who built what before us.

Why Agencies Use Backline Instead of Hiring a Developer

A full-time senior WordPress developer costs six figures and sits idle between builds. A freelancer disappears mid-project. Direct offshore hiring hands you timezone gaps, vetting risk, and rebuilds.

Backline is the fourth option: US-led account management with a vetted global development team, all working CST hours. You get senior-level WordPress development on demand, code review on every change, and a team that’s still here next quarter. Overflow work when your developer is buried, or the entire dev function if you’ve never had one.

Why Agencies Use Backline Instead of Hiring a Developer

What Our Developers Handle for Agency Partners

  • Custom Features & Plugins – Functionality built to spec when no plugin exists: custom post types, admin interfaces, WooCommerce extensions, and one-off client requests.
  • Advanced Custom Fields Builds – Structured, client-proof editing experiences with ACF, so your clients can update content without breaking layouts.
  • API & Third-Party Integrations – CRMs, payment gateways, marketing platforms, SSO. If it has an API, we’ve probably wired WordPress to it.
  • Custom E-commerce – Advanced WooCommerce checkout flows, payment integration, subscriptions, and inventory logic.
  • Site Fixes & Rescues – Hacked sites, critical errors, white screens, plugin conflicts, broken builds inherited from previous developers.
  • Performance Optimization – Code refinement, caching, image and media optimization, and server tuning for Core Web Vitals.
  • Security Hardening – SSL, firewalls, malware protection, and the patching discipline that’s kept our maintained sites unhacked.
  • Database Management – Setup, optimization, and cleanup so client sites stay fast as they grow.
  • Bug Fixing & Troubleshooting – The “small” tickets that eat your team’s week: broken links, layout bugs, form failures, update fallout.
