WordPress development for sites that can’t afford to break.
Grendesign builds and looks after custom WordPress and WooCommerce sites for Australian businesses that rely on them for leads, sales or daily operations. We do custom themes and plugins, integrations, migrations, performance work and ongoing support, with staging, version control and rollback on every change. Our team works from Mornington and Sydney.
For marketing and operations teams who need a developer who answers, not a ticket queue.
- 16+ years
- Custom plugins & integrations
- Staging and rollback on every release
The site works. Nobody wants to touch it.
Thirty plugins, a theme nobody remembers buying, and updates that get skipped because the last one took the checkout down. Meanwhile marketing waits weeks for a landing page. That isn’t a WordPress problem. It’s a build problem.
Every change is a risk
No staging site, no version control, no way back. So changes stop, and the site falls behind.
Speed costs you leads
Slow pages lose people before the form loads, and Google notices too.
Systems don’t talk
Leads get copied into the CRM by hand. Stock gets updated twice. Someone always forgets.
What we build and look after
Everything is documented, version-controlled and tested on staging before it goes near your live site.
Custom themes and blocks
Built for your content team, so they can publish a new page without breaking the layout or calling us.
Custom plugins
When off-the-shelf plugins don’t fit, we write lean ones that do one job and are easy to maintain.
Integrations
CRM, ERP, booking, payment and data feeds. Farrells Bookshop’s daily BookNet and NielsenIQ imports are one example.
Migrations and rebuilds
From old themes, page builders or other platforms, with redirects mapped so you keep your search rankings.
Performance and security
Caching, image handling, Core Web Vitals, hardening and monitoring.
Support retainers
A set number of developer hours each month, updates on staging first, and a named person who knows your site.
How it runs, week by week
One named lead, fixed checkpoints and nothing goes live without your sign-off.

Questions we get asked
How much does a WordPress developer cost in Australia?
Agency WordPress work in Australia is usually charged by project or as a monthly retainer of developer hours. Custom builds with integrations typically land in five figures. We quote after an audit, so you’re paying for what your site needs.
Can you take over a site another agency built?
Yes. We start with an audit, back everything up and set up staging before changing anything.
Do you build custom WordPress plugins?
Yes, when it’s the right call. If a well-supported plugin already does the job, we’ll tell you and save you the money.
Will a rebuild hurt our Google rankings?
It can if redirects and content are handled badly. We map every old URL, keep what ranks and check Search Console after launch.
Do you work with WooCommerce?
Yes, including large catalogues, product feeds, custom checkout steps and stock integrations.
Is WordPress secure enough for a larger business?
Yes, when it’s maintained. Most WordPress breaches come from outdated plugins and weak passwords, both of which a proper support plan handles.
Do you offer hosting?
We can host, or work with your existing hosting or IT provider. Either way we set up backups, monitoring and a staging copy.
Can you integrate WordPress with our CRM?
Usually, yes: HubSpot, Salesforce, Zoho, Pipedrive and others through their APIs or tools like n8n and Zapier.
How do we request changes?
Through one channel with a named developer. Urgent issues get handled first, and everything else is planned in priority order.
Do you work in Sydney and Melbourne?
Yes. Our team works from Mornington and Sydney, with clients across Australia.
