// what white-label development means here

Not a theme swap. Not a plugin configuration. Custom software — built from scratch — delivered under your name.

Every project below started with a client problem no existing tool could solve — a booking system that needed a full payment lifecycle, a job board that needed to sync from an enterprise ATS, an SEO strategy that needed hundreds of pages generated automatically from live data. Off-the-shelf plugins don't do this. We write the code that does.

model 01 · agency white-label

You own the client relationship.

You present, you manage, you invoice. We build quietly in the background — under your agency name or brand. The code ships with your author credits, your domain, your identity. We never appear in client-facing deliverables unless you want us to.

model 02 · direct engagement

We're the dev team you don't have in-house.

For businesses that need custom software but don't want to hire an engineering team. We embed alongside your operation, build what you need, and hand off code you own outright — documented, validated, and deployable on your infrastructure.

// what we've built · example 01

A complete booking-fee intake engine for a home services company.

When an established home services business needed to take paid bookings online — with a multi-step qualifier, a booking fee, and a full job lifecycle behind it — there was no plugin for it. We built it.

// industry · home services & contractor booking

Service intake + booking-fee funnel with a full lifecycle engine.

The problem: a service company needed customers to answer qualifying questions, pay a booking fee, and enter a managed job pipeline — all from a WordPress site. WooCommerce could take a payment. It couldn't own a booking or run a lifecycle. We built a plugin that could.

// plugin architecture
layer 01

Service CPT

Each service is a native WordPress custom post type. Pricing, lead time, site-visit requirements, and the entire qualifier flow are managed per-service in the admin dashboard — no code changes needed to add a new service or change a fee.

layer 02

Qualifier flow builder

A dashboard-configurable step builder lets the admin define any number of qualifier questions with multiple-choice options per service. The funnel reads the flow from the CPT — code owns the behavior, the client owns the content.

layer 03

Booking entity + lifecycle

The booking is a first-class database entity — not a WooCommerce order. It owns its own status machine and persists through every phase from intake to job completion, with WooCommerce used as an invisible payment subprocessor behind a pluggable adapter.

layer 04

Payment adapter layer

An interface contract means WooCommerce is one implementation, not a dependency. Switching to Stripe direct or any other processor in the future is an adapter swap, not a rewrite. A null adapter handles dev/testing environments.

layer 05

Dual contact record

Contact data is stored in two layers: the original funnel-session capture (what they typed in the qualifier — never overwritten) and the final WooCommerce billing details (which the customer can edit at checkout). Both are linked to one booking for CRM use.

layer 06

Notifications

Lifecycle-driven transactional emails for every event — new booking alert to admin, fee-paid confirmation to customer with booking reference, next-steps messaging. Every subject, body, and recipient is filterable without touching code.

Booking lifecycle — full status vocabulary

pending_payment fee_paid site_visit_scheduled assessed quoted work_scheduled completed cleared  ·  cancelled  ·  refunded

Full status vocabulary defined at v1 — the funnel only creates pending_payment and advances to fee_paid on payment. Every downstream phase of the job lifecycle is already modeled, so later additions never have to redefine it.

Configurable booking fee

Fee is resolved per service via a filterable function — not a WooCommerce product price. Flat fee at launch, trivially upgradeable to region/scope/market pricing as a one-place change with zero downstream breakage.

Homepage funnel router

A [home_funnel] shortcode surfaces up to 4 featured services on the homepage with their own taglines, page URLs, and display order — all managed from the admin dashboard, no code deploy needed.

Admin bookings dashboard

A full bookings table in the WordPress admin — searchable, filterable by status, showing original funnel capture alongside confirmed billing details and WooCommerce order ID for cross-reference.

Qualifier answers in admin emails

Every admin notification includes the customer's qualifier answers mapped to their human-readable option labels — so the team receiving the booking knows exactly what was scoped before they open WordPress.

Flow seeder for onboarding

A flow seeder installs sample services and qualifier flows on activation — the admin can immediately see a working funnel without building one from scratch, then customize in place.

Clean uninstall policy

Deactivation only flushes rewrite rules. Uninstall.php has an explicit preserve-by-default policy — deleting the plugin keeps all settings and booking data. Optional purge block is present but disabled, for operators who want true full removal.

// what we've built · example 02

A two-plugin system that syncs a live ATS and auto-generates hundreds of SEO location pages.

A national staffing company needed their job board to pull live from their ATS, display with filtering and a map, and auto-generate unique SEO-optimized pages for every state and city where they place talent. No existing tool does all three.

// industry · staffing & workforce solutions

ATS API sync + AI-powered location page generation at scale.

The business had jobs in their ATS. They needed those jobs on their WordPress site — live, filterable, with a map — and they needed to rank in every city and state they served. We built two plugins that work as a system: one that owns the data, one that owns the pages.

// plugin architecture · two-plugin system
plugin 01 · ats jobs

The data layer.

  • JWT authentication exchange with the ATS API — auto-renews on every sync cycle
  • 15-minute cron sync fetches all active job records and stores them locally
  • Geocoding cache — each unique location geocoded once, cached persistently, never re-fetched unless the address changes
  • Location normalization engine — collapses "Detroit, Michigan," "Detroit, MI," and "Detroit, MI 48226" into one consistent filter option
  • [ats_jobs_list] — filterable job grid with keyword search, city/state filter, publishOnline gating
  • [ats_jobs_single] — full job detail page with all ATS fields
  • [ats_jobs_map] — interactive map of all active job locations
  • [ats_jobs_search] — standalone search bar embeddable anywhere on the site
  • Admin preview table with last-sync timestamp, job count, and manual sync trigger
  • Structured logger — sync events, geocode hits/misses, and API errors all go to a dedicated log table queryable from the admin
plugin 02 · location pages

The SEO layer.

  • Depends on ATS Jobs — location data comes from the live sync, no separate data entry
  • Custom post type (job_location_page) — one CPT record per state, one per city, all managed automatically
  • Location normalizer groups every synced job by state slug and city slug — pages are created, updated, or drafted based on where live jobs actually exist
  • AI content generation per page — OpenAI integration writes 500–600 word, heading-structured, unique content for every state and every city, using the client's voice profile from settings
  • Pages auto-draft when a location has no active jobs — no dead pages ranking for places with nothing to offer
  • Daily content refresh cron — pages with stale content or changed job counts get regenerated automatically
  • Hooks into ATS Jobs sync completion — new locations get pages created within 15 minutes of appearing in the ATS
  • Admin regenerate-on-demand — any page can be manually regenerated from the WP admin

Legacy website migration plugin — included in the same engagement.

A third plugin crawled the client's existing legacy website — scraping pages and media assets and storing them in a structured internal database — without creating WordPress posts or pages. This preserved the full content archive while the new site was being built, with zero manual copy-paste. A purpose-built tool for a specific migration problem, built alongside the main system, deployed in the same codebase.

// every white-label engagement includes

Not just code. A complete, handoff-ready deliverable.

🏗️

Modular architecture

No monolithic files. Every responsibility lives in its own class. Files stay under 800 lines. The plugin is easy to pick up, maintain, and extend — by us or by whoever comes next.

Validated on delivery

Every file passes PHP syntax validation and JS syntax checks before it leaves our hands. BOM detection, file size warnings, and form-nesting tests run as part of the build process. [PASS] required before handoff.

📄

Documented handoff

Context docs, changelog, state notes, and decisions logged throughout the build. You receive a complete picture of what was built, why, and what comes next — not just a zip file.

🔒

Security-first code

Nonce verification, permission checks, input sanitization, and output escaping throughout. Import/export validation rejects PHP serialized payloads. Clean uninstall policy preserves data by default.

🔌

Pluggable by design

Payment adapters, AI providers, notification recipients, email bodies — all filterable via WordPress hooks. The client can customize behavior without touching core plugin code.

🚀

WordPress standards

Custom post types, REST API endpoints, shortcodes, cron scheduling, and admin UI all follow WordPress coding and security standards. No reinventing the wheel; no fighting the platform.
