WooCommerce development services for stores that have outgrown their extensions
My WooCommerce development services are for store owners who have hit the limits of their theme and extensions: a checkout that needs extra fields, a payment gateway with no reliable plugin, product rules no extension handles, or a store that slows down as orders pile up. I build and fix those things in PHP, against current WooCommerce, so the store keeps working through updates. You talk directly to the developer who writes the code.
What’s included
- New WooCommerce stores on a lean theme, with products, shipping zones, taxes and emails configured, built from your own design if you have one (Figma to WordPress)
- WooCommerce customization of product pages, cart, checkout, transactional emails and My Account
- WooCommerce custom checkout fields, steps and validation that work with the block-based checkout
- Payment gateway setup and custom gateways for Stripe, PayPal, Razorpay and regional providers
- Shipping, inventory, ERP and accounting integrations through the WooCommerce REST API and webhooks
- HPOS migration and compatibility fixes for custom code and older extensions
- Store speed fixes: autoloaded options, Action Scheduler backlog, slow order queries, object caching
- Custom WooCommerce development of product types, pricing rules, B2B and wholesale features
WooCommerce development services for growing stores
WooCommerce development services cover the work between installing WooCommerce and having a store that fits how you actually sell. Sometimes that means building a new store, but more often it means custom WooCommerce development on a live store: changing checkout, adding a pricing rule, connecting stock levels to a warehouse system, or fixing an extension conflict that appeared after an update.
This page is for stores selling physical or digital products that need changes beyond settings and off-the-shelf extensions. If you only need a few products online with a standard checkout, stock WooCommerce with a good theme is enough, and I will say so. If you are on Shopify and happy there, moving is rarely worth the effort unless you have hit a real limit such as fees, custom pricing or data ownership.
WooCommerce custom checkout: blocks, fields and payment gateways
Checkout is where most WooCommerce customization requests land, and it is also where most outdated advice lives. Since WooCommerce 8.3, new stores use the block-based Cart and Checkout by default. Snippets that filter woocommerce_checkout_fields or print HTML on classic checkout hooks are never called by the block checkout, which is why so many copied tutorials seem to fail silently.
For a WooCommerce custom checkout today I use the Additional Checkout Fields API for extra fields such as a GST number, company details or delivery instructions, Store API extensions for data that must reach the order, and the classic shortcode checkout only when an extension you rely on still needs it. Validation always runs on the server, not just in the browser.
Payment gateways follow the same split: a gateway written only for the classic checkout does not appear in the block checkout until it registers a block integration. I set up Stripe, PayPal and Razorpay through their official extensions where a maintained one exists, and build custom gateways with signed webhook verification and correct order status handling when it does not. My payment gateway integration service and the Razorpay vs Stripe comparison go deeper on choosing a provider.
HPOS compatibility and keeping a store upgrade-safe
High-Performance Order Storage (HPOS) moves orders out of the WordPress posts and postmeta tables into dedicated order tables. It has been enabled by default for new installs since WooCommerce 8.2, and older stores can switch under WooCommerce > Settings > Advanced > Features after a compatibility sync. The gain is real for order-heavy stores, but only when every piece of custom code is ready for it.
Before a switch, I audit the theme, custom plugins and snippets, rewrite order access through wc_get_order and the CRUD methods, run compatibility mode on staging, and compare order counts and totals between both storage systems before production changes over. These are the problems I look for:
- Code that reads orders with get_post_meta or WP_Query on shop_order, which returns nothing once HPOS is the source of truth
- Custom plugins that never declare HPOS compatibility, which keeps WooCommerce from letting you enable it
- Direct SQL against order data, common in old reporting and export scripts
- Subscription and booking extensions that must stay active during the migration so their data syncs correctly
Why hire a WooCommerce developer who works in PHP every day
When you hire a WooCommerce developer, you are trusting someone to work inside a live sales system where mistakes cost orders. My daily work is PHP 8, Laravel and MySQL on billing and back-office systems where transactions, row-level locking and data integrity matter, such as the brokerage risk platform where I am a core developer and team lead. The same care goes into stock updates, order status changes and payment webhooks in WooCommerce.
Most WooCommerce developers for hire are found through marketplaces or agencies, where the person you brief is not the person coding. With me, the person scoping the change writes the code and answers your messages. I am based in India and work with stores worldwide, and I understand what Indian stores usually need: GST details on invoices, Razorpay, and courier aggregators such as Shiprocket. I work remotely with clients in different time zones and we agree on update times at the start.
My WooCommerce client work is private, so it is not in the public portfolio. I can walk you through relevant work on a call.
Why WooCommerce stores slow down as they grow
A store that was fast at launch often slows down after a year of orders, and the theme is rarely the main cause. The usual suspects are a wp_options table full of autoloaded data left by removed extensions, an Action Scheduler table holding hundreds of thousands of old completed or failed actions, postmeta-heavy order queries on stores not yet on HPOS, uncached cart fragment requests, and admin screens running heavy reports on every load.
I measure first with Query Monitor and server logs, fix the database and code causes, then add page and object caching (Redis where the host supports it) with correct exclusions for cart, checkout and account pages. For a full front-end and Core Web Vitals pass, see WordPress speed optimization.
What affects the cost of WooCommerce development
I give a fixed quote after a short call or a written brief, with a dated plan. The main drivers are:
- A new store versus changes to a live store, where work happens on staging and deploys without losing orders
- Checkout type: block checkout, classic checkout, or both if an extension requires it
- Product count, variations and import sources, and whether the data needs cleaning first
- Payment and shipping providers, especially ones without a maintained extension
- Integrations with ERP, accounting, inventory or marketplaces, and the quality of their APIs
- HPOS migration and the number of custom snippets and extensions to audit
How the work runs
Store audit
I review your WooCommerce, WordPress and PHP versions, extensions, custom snippets, checkout type, HPOS status and slow queries, then list what to fix and in what order.
Scope and fixed quote
We agree on the changes, the acceptance tests (for example, a successful test order through each gateway) and a dated plan.
Build on a staging copy
Work happens on a staging copy with customer data anonymized, so I can test real products and flows without touching live orders or emailing customers.
Test orders and edge cases
Test purchases through every gateway, plus refunds, coupons, stock limits, tax and shipping zones, and guest and logged-in checkout on phones and desktop.
Deploy and monitor
I deploy at a quiet time with a fresh backup, then watch new orders, payment webhooks and error logs over the following days.

Questions
Can you customize the WooCommerce checkout page?
Yes. I add fields, steps, validation and conditional logic on both the block-based checkout and the classic shortcode checkout. On the block checkout I use the official extension APIs, so the changes survive WooCommerce updates.
Can you integrate Razorpay, Stripe or a local payment gateway?
Yes. I use the official extension where a maintained one exists and build a custom gateway when it does not, with server-side payment verification and webhook handling. I make sure the gateway works in the block checkout as well as the classic one.
How do I know if my store is ready for HPOS?
Start with WooCommerce > Settings > Advanced > Features, which lists extensions that have not declared compatibility. Custom snippets and theme code are not listed there, so I also search them for direct order post meta and SQL before you switch.
Can you speed up a slow WooCommerce store?
Yes. I find the cause first, usually database bloat, background job backlogs or slow queries, then fix it and add caching that does not break cart and checkout. You get before and after measurements, so the improvement is visible rather than assumed.
Can you build a custom WooCommerce plugin or feature?
Yes. Custom product types, pricing rules, B2B features and order workflows are built as standalone plugins so they survive theme changes. My custom WordPress plugin development page explains how I write them.
Do you provide ongoing WooCommerce support?
Yes. I can test core and extension updates on staging before they reach the live store, fix issues as they appear and make small changes on request. A store needs more care than a brochure site, because a broken checkout costs sales immediately. If a store has already been hacked, for example with injected scripts on the checkout page, that is a cleanup job first: see WordPress malware removal.
