Themes We Build

From bespoke corporate themes to WooCommerce storefronts and Full Site Editing block themes — engineered for performance, accessibility, and editor experience.

Custom Corporate & Agency Themes

Pixel-perfect custom themes built from Figma designs — bespoke templates, page builder integration where it helps, and a CMS structure your marketing team can actually update.

Full Site Editing (FSE) Block Themes

Modern block themes with theme.json, block patterns, block variations, custom blocks, and Site Editor templates — for editors who deserve a 2026-era authoring experience.

ThemeForest & WordPress.org Releases

Public theme releases — demo content, documentation, screenshots, review preparation, support runbook, and version maintenance after launch.

Child Themes & Parent Customisation

Child themes for Astra, GeneratePress, Hello (Elementor), Storefront, and others — clean override layers that survive parent-theme updates.

Our WordPress Theme Process

A six-step rhythm engineered so launch day is a celebration — not a backlog of accessibility bugs and Core Web Vitals violations.

01

Discovery & Brand Audit

We understand your brand, audience, content depth, conversion goals, and whether you need a custom theme, a child theme, or a FSE block theme.

02

Design System in Figma

Wireframes, mood boards, type scale, colour tokens, and high-fidelity designs — with responsive breakpoints and accessibility states defined up front.

03

Theme Build & theme.json

Templates, parts, block patterns, theme.json with design tokens, custom blocks where needed, and WooCommerce templates if applicable — all WordPress-coding-standards clean.

04

Performance & SEO

Core Web Vitals tuned (LCP, CLS, INP), schema markup, OpenGraph, sitemaps support, image/font optimisation, lazy loading, and Lighthouse target of 95+.

05

Accessibility & QA

WCAG 2.2 alignment, keyboard navigation, screen-reader semantics, focus management, RTL support, and cross-browser/cross-device QA on real devices.

06

Launch & Maintenance

DNS cutover, demo content, editor handoff documentation, monthly retainer for WordPress upgrade compatibility, security patches, and feature additions.

Why Choose Hendoi for WordPress Themes

Six commitments that decide whether your theme wins on Core Web Vitals — or quietly drags the whole site\'s rankings down.

Performance Obsessed

95+ Lighthouse scores by default. No bloated page builders shipping 200KB of unused CSS. Optimised images, fonts, lazy loading, and clean PHP — every theme tuned for Core Web Vitals.

FSE & Block-Theme Expertise

theme.json, block patterns, block variations, custom blocks with React, and Site Editor templates. Editors get a modern, Figma-like authoring experience.

WooCommerce Storefront Expertise

High-conversion storefronts — optimised PDP, AJAX cart, mini-cart, fast checkout, payment-gateway styling, GST invoices, and Indian-market patterns built in.

Accessibility-First

WCAG 2.2 AA aligned — keyboard navigation, screen-reader semantics, focus management, colour contrast, and skip links. Your theme is usable by everyone.

SEO Built In

Schema markup, OpenGraph, Twitter cards, breadcrumbs, semantic HTML, fast loads, and editor-friendly meta controls — your theme ranks, not just looks pretty.

Transparent Engagement

Weekly demos on a staging site you can poke at, direct access to designers and engineers, milestone-based pricing with documentation deliverables defined, predictable burn.

Engagement Models

Pick the shape that matches whether you need a private theme, a public marketplace release, or ongoing theme engineering capacity.

Frequently Asked Questions

Common questions agencies, store owners, and theme authors ask before committing to a WordPress theme build.

Custom theme or page builder — which is better?
For brand-led, performance-critical sites: a custom theme with FSE blocks. For agility-first marketing sites with non-technical editors: a custom theme with curated block patterns and limited page-builder usage. We avoid Elementor/Divi-style page builders for performance-sensitive projects — they ship too much unused CSS/JS.
What is a Full Site Editing (FSE) block theme?
A block theme uses block templates, block patterns, and theme.json to define the entire site visually inside the Site Editor — no PHP template files needed for most layouts. It is the WordPress-recommended path for new themes and gives editors a Figma-like authoring experience.
Can my marketing team edit content?
Yes — that is the whole point. We design block patterns, structured content models, and CMS workflows your marketing team will actually enjoy. No more "please open a ticket to change a headline" situations.
Do you work with WooCommerce?
Yes — custom WooCommerce storefronts, optimised PDP, AJAX cart, fast checkout, payment-gateway styling (Razorpay, PayU, Stripe), GST invoicing, and conversion-focused UX patterns.
How fast will the theme be?
We target 95+ Lighthouse scores on mobile and desktop. Core Web Vitals (LCP under 2.5s, CLS under 0.1, INP under 200ms) are non-negotiable. No bloated page builders shipping unused CSS/JS — clean PHP, optimised assets, and lazy loading.
Can you list a theme on WordPress.org or ThemeForest?
Yes — we build to review-team standards from the start. Demo content, documentation, screenshots, accessibility passes, and coordination with reviewers. We have shipped themes to both marketplaces.
How long does a theme take to build?
A custom corporate theme: 6-10 weeks. A WooCommerce storefront: 8-14 weeks. A publishable theme with demo content + documentation: 12-20 weeks. We share milestones with weekly Figma and staging demos.
Do you handle post-launch maintenance?
Yes — monthly retainers covering WordPress core compatibility, WooCommerce upgrade compatibility, security patches, new block additions, design tweaks, and editor support.
