WordPress partnership FAQs
Clear answers about scope, CMS editing, existing websites, enterprise requirements, QA and white-label delivery.
You can hand over a complete marketing or service website, an approved Figma design, a landing page, a rebuild or agreed work on an existing site. We confirm the deliverables, required access and current priority before starting.
Yes. We review the approved desktop and mobile direction, clarify any missing states, then develop the site responsively. Your team reviews the build before it is presented or launched.
Yes. Before development begins, we agree which content the client needs to manage. The editing setup and reusable sections are then planned around those needs instead of leaving the client with an unclear backend.
Yes. We can handle agreed bug fixes, responsive repairs, new landing pages, migrations and improvements while the subscription is active. The current priority is agreed with your team before work begins.
WooCommerce, custom plugin engineering, complex integrations and application-style functionality are reviewed and scoped separately. We confirm that before work starts, so a technically complex brief is not presented as a standard marketing website.
The standard Website Partner plan is designed for custom marketing and service websites. Enterprise requirements such as multisite, SSO, complex integrations, high-traffic architecture, governance or compliance need separate technical discovery and scoping before we confirm capability, price and timeline.
Only when your agency explicitly asks us to. We can work entirely behind your team, sign an NDA and communicate through Slack, email or your agreed project-management system.
We need the approved scope, designs or design brief, final content, brand assets, functional requirements and relevant access. The delivery timeline starts only after the materials required for the current stage are ready.
Responsive behaviour, page structure, forms and agreed functionality are checked before launch. Standard technical foundations such as semantic headings and indexable page structure can be included; specialist SEO campaigns and ongoing optimisation are separate services.
A smaller website generally needs at least seven working days and a larger website at least fourteen. Timing starts after the required brief, content, designs, access and approvals are ready and varies with scope and feedback.
