Most WooCommerce problems trace back to the same cause: too many plugins doing too little, and code written around the platform rather than with it. KiwiCommerce is a UK-based WordPress and WooCommerce agency. Our dedicated WooCommerce developers build cleanly, choose plugins deliberately, and write custom code that stays compatible with WooCommerce core updates. 250+ projects completed since 2016.
The most common cause of WooCommerce problems is not bad luck; it is bad build decisions. A plugin for every requirement, custom code that bypasses the hook system, and no staging environment before changes go live. Our WooCommerce web developers make deliberate choices at every step: custom code for what is unique, well-maintained plugins for standard functionality, nothing installed without justification.
Get In TouchEvery active plugin on your store has a maintenance cost and a conflict risk. We install what earns its place and write custom code where a plugin would create more problems than it solves.
Our developers write to WooCommerce's action and filter system correctly. Code that follows the platform's own architecture survives core updates. Workarounds do not.
Nothing we build goes directly to your live WooCommerce store. All changes to custom plugins, theme updates, and core version changes are tested in staging first.
Our team works across WooCommerce, Shopify, and Magento. If WooCommerce is not the right platform for your project, we will tell you before work starts, not after.
WooCommerce gives you complete ownership of your store: the data, the hosting, the checkout logic, the code. No monthly platform fees, no transaction cuts taken by the platform, no ceiling on what can be customised. The trade-off is that it needs proper development to perform well, and proper maintenance to stay secure as it grows.
Plugin stacking is where most WooCommerce stores run into trouble. A plugin for every requirement sounds practical until three of them conflict with each other, a WooCommerce core update breaks two more, and load times climb to the point where Core Web Vitals scores start affecting search rankings. Our expert WooCommerce developers write custom code for unique requirements and use plugins only where they are the correct tool.
Performance on WooCommerce depends on more than hosting. HPOS (High Performance Order Storage) handles order processing speed at volume, but page speed, checkout speed, and stability under load all depend on caching configuration, PHP setup, database health, image handling, and theme architecture. We audit each layer separately.
With 250+ projects delivered and over 100 live stores on retainer, we have built, fixed, and maintained WooCommerce stores across retail, B2B, and wholesale. The retainer figure matters: clients who keep us on after a build are clients whose stores are running cleanly.
Discuss Your Project2+ Experience Years
Builds purpose-built WooCommerce plugins to WordPress and WooCommerce coding standards. These developers understand the hook and filter architecture in full, writing extensions that stay compatible with WooCommerce core updates, rather than breaking on the next release. For businesses that need bespoke product types, custom pricing logic, unique order workflows, or proprietary integrations that the plugin marketplace does not cover.
5+ Experience Years
For WooCommerce stores that are slow, unstable under load, or progressively getting worse as the plugin stack grows. Carries out structured audits covering hosting configuration, PHP setup, and caching layers, database query health, plugin conflicts, image handling, and theme architecture. Identifies the actual causes rather than applying generic fixes, most slow WooCommerce stores have more than one contributing factor.
7+ Experience Years
Builds trade account functionality on WooCommerce: tiered pricing by customer group, minimum order quantities, restricted catalogues by account type, and wholesale checkout flows. Where the WooCommerce B2B plugin ecosystem does not cover the full buying workflow, multi-step approvals, quote-based ordering, and PO payment terms, write the additional logic as a custom plugin built to platform standards.
5+ Experience Years
Handles migrations to WooCommerce from Shopify, Magento, PrestaShop, OpenCart, and bespoke platforms. Before starting, assesses data structures, custom functionality, and integration dependencies to produce a migration plan without mid-project surprises. Products, customers, and order history are migrated with validation. Redirects are mapped and live before go-live to protect search rankings built on the previous platform.
5+ Experience Years
Complex custom plugin development, bespoke checkout architecture, advanced REST API and ERP integrations, B2B WooCommerce builds, and enterprise performance tuning. Leads large WooCommerce projects, makes architecture decisions that determine long-term store health, and reviews work produced by junior team members before it reaches staging. These developers know where WooCommerce's defaults will cause problems at scale before they are written.
7+ Experience Years
For complex WooCommerce projects, the technical decisions made before development starts determine whether a store stays manageable as it grows. Assesses requirements, evaluates platform fit, designs the plugin stack and integration architecture, and defines the hosting and caching strategy before development begins. Prevents the most expensive WooCommerce problem: a store that works at launch and degrades over the following twelve months.
What You Get When You Hire Our WooCommerce Team
Purpose-built WooCommerce plugins written to WordPress coding standards using the WooCommerce hook and filter system correctly. These plugins stay compatible with WooCommerce core updates rather than breaking on the next release. Built for requirements the plugin marketplace does not cover: bespoke pricing logic, custom product types, proprietary integrations, and unique order workflows.
Structured audit covering hosting configuration, PHP memory and version settings, caching layers (Redis, Varnish, Cloudflare), database query, health, plugin bloat, image handling, and theme architecture. We identify the actual causes of a slow WooCommerce store, which are usually several at once, and resolve them in priority order rather than applying a generic speed fix.
Trade account setup with customer-group pricing, tiered discount rules, minimum order quantities, restricted catalogues by account type, and wholesale checkout flows. Extended with custom plugin development where the native WooCommerce B2B ecosystem does not cover your full buying process, quote-based ordering, PO payment terms, or multi-step purchase approvals.
Bidirectional connections between WooCommerce and inventory management systems, accounting software (Sage, Xero, QuickBooks), CRM platforms, and fulfilment systems. Built using the WooCommerce REST API and custom webhook configurations with proper error handling, not fragile point-to-point connections that break when either system updates.
Migrations to WooCommerce from Shopify, Magento, PrestaShop, OpenCart and bespoke eCommerce platforms. Full data migration with validation of products, customers, and order history. Redirect mapping is implemented before go-live, so existing search rankings are not lost in the transition. Custom functionality from the source platform is rebuilt natively in WooCommerce or replaced with equivalent plugins.
Retainer-based support covering WordPress and WooCommerce core updates, plugin compatibility management, security patching, performance monitoring, and ongoing custom development. We currently support over 100 live stores in this capacity. WooCommerce needs more active maintenance than hosted platforms. You manage your own hosting and plugin stack, and a lot can go wrong without regular oversight.
Most WooCommerce agencies build stores that work at launch. The question is whether they still work cleanly six months later, when the plugin stack has grown, and the platform has updated twice.
WooCommerce has a defined architecture: actions, filters, and a service layer for extending the platform correctly. Developers who bypass it with direct database queries or hard-coded overrides create code that works until the next core update, then breaks unexpectedly. Our WooCommerce developers write to platform standards, which means the code they deliver keeps working as the platform develops.
Installing a plugin for every requirement is the single most common cause of WooCommerce performance problems and plugin conflicts. Our developers evaluate each requirement separately: if a maintained plugin covers it cleanly, use it. If not, write a targeted custom plugin instead. This discipline keeps the active plugin count low, load times manageable, and the maintenance overhead sustainable.
Slow WooCommerce stores rarely have a single cause. The most common mistake is addressing hosting without looking at the PHP configuration, or improving caching without fixing the database queries, causing the slowdown. Our performance specialists audit every layer, hosting, PHP, caching, database, plugins, images, and theme architecture and resolve causes in order of impact, not in order of ease.
KiwiCommerce works across WooCommerce, Shopify, and Magento. That means we can give you a platform comparison that is not motivated by which platform we prefer to build on. For some businesses, WooCommerce is the right choice. For others, those needing enterprise B2B or very high order volumes, a different platform fits better. We tell you which, and why, before a build starts.
For agencies with WooCommerce clients who need a certified development resource without adding headcount, we operate as your white-label WordPress and WooCommerce partner. Your client sees your brand throughout. Nothing references KiwiCommerce in code, commits, or documentation. NDAs are signed on every engagement, and we currently work with multiple agencies in this capacity.
Supporting over 100 live eCommerce stores on active retainers is evidence that builds are clean enough to maintain, and client relationships are worth continuing. WooCommerce needs regular attention: WordPress and WooCommerce core updates, plugin compatibility checks, and performance monitoring all need a team that knows the store. Starting a fresh developer search every time something needs attention is slower and more expensive.

WooCommerce is the right choice for businesses that want full ownership of their store data, need deep customisation that hosted platforms cannot offer, or already operate on WordPress. It is not the easiest platform to set up, and it requires proper ongoing maintenance. For businesses needing enterprise-level B2B or very high order volume, Magento or Shopify Plus may be a better fit. We can advise on the platform before you commit.
A WooCommerce developer builds and maintains eCommerce stores on WordPress using WooCommerce as the core plugin. The work ranges from store builds, custom checkout flows, and plugin development through to ERP integrations, B2B trade account setups, performance investigations, and platform migrations. The specialism required depends on what your project needs; a plugin developer and a performance specialist are different roles.
Slow WooCommerce stores almost always have more than one cause. Common factors include inadequate hosting configuration, PHP memory limits set too low, no object caching, an oversized plugin stack with overlapping or conflicting functionality, unoptimised database queries, and uncompressed images. We carry out a structured audit covering each of these layers, identify what is actually causing the slowdown, and fix the causes in priority order.
Yes. Custom WooCommerce plugin development is a core part of our work. We build plugins to WordPress and WooCommerce coding standards using the hook and filter system correctly, so they stay compatible with WooCommerce core updates. For functionality the plugin marketplace does not cover: custom pricing logic, bespoke product types, unique order workflows, proprietary integrations, and custom checkout fields.
Before starting any migration, we assess the source platform’s data structures, custom functionality, and integration dependencies to produce a clear migration plan. Products, customers, and order history are migrated with validation. Redirects are mapped and implemented before go-live to protect existing search rankings. Custom functionality from the source platform is rebuilt natively in WooCommerce or replaced with equivalent plugin solutions.

Yes. Migrations from Shopify, Magento, PrestaShop, and OpenCart are a regular part of our work. We assess data structures and custom functionality before agreeing on a plan. Products, customers, and order history are migrated with validation. Redirects are mapped before go-live to protect your search rankings. Custom functionality on the source platform is either rebuilt in WooCommerce or replaced with a suitable plugin equivalent.
Retainer support covers WordPress and WooCommerce core updates, plugin compatibility management, security patching, performance monitoring, and ongoing custom development. We currently support over 100 live eCommerce stores in this capacity. WooCommerce requires more active management than hosted platforms because you are responsible for your own hosting environment and plugin stack, and that needs consistent, experienced oversight.
