Implement a design
Turn layouts into responsive pages, reusable components and WordPress content areas. We define the necessary views and functionality before implementation.
WordPress & WooCommerce development for agencies
Bring us the design, brief or website your client needs to improve. We develop WordPress websites, WooCommerce stores, campaign front-ends and integrations, with the scope and delivery responsibilities settled before work begins.
Keep the strategy, creative direction and client relationship with your agency. Testin joins as your development subcontractor, with communication, reviews and handover agreed for the project.
A role that fits your team
Turn layouts into responsive pages, reusable components and WordPress content areas. We define the necessary views and functionality before implementation.
Create or improve landing pages, enquiry forms and store features that your marketing work depends on.
Define the data flow and integration scope with the people responsible for the connected systems, before estimating the development.
Plan fixes, updates and further development for an existing client website. The first step is a review of its condition and the support responsibilities.
Before the first line of code
Send the public site address or design link and the change your team needs. Before implementation, agree the scope, responsibilities and how the result will be reviewed.
For a change, include the affected page, what happens now and what should happen instead. For a new build, share the required views, components and functions. Add constraints and priorities so we can clarify the task.
Identify who supplies copy, images, design states and integration details. Agree any missing materials and dependencies. Define the necessary permissions and arrange access separately through named accounts.
Choose one person to consolidate feedback and approve the result. Define acceptance criteria, key journeys, devices and relevant accessibility checks. Separate corrections within the agreed task from requests that change its scope.
Agree who approves and publishes changes, what should be checked before release and what materials the team will receive. Record remaining work, licence responsibilities and any separate maintenance needs before closing the task.
A role that fits your agency
Start with one defined task or discuss a broader build. We agree the delivery role, client contact and review process around the way your agency works.
Your agency supplies the creative direction and approved layouts. Testin implements the agreed WordPress pages, WooCommerce features or campaign front-end.
A useful starting brief: required views, responsive states, content areas and integrations.
Bring us a defined improvement, recurring issue or set of development tasks. We review the website and dependencies before confirming the work.
A useful starting brief: the site address, what happens now and what should happen instead.
Keep your agency at the centre of the client relationship. Agree how Testin contributes behind the scenes, who consolidates feedback and how the work is handed over.
A useful starting brief: your delivery process, communication preferences and confidentiality requirements.

Explore the projectPeople behind the work
We are an agency in Rzeszów, Poland, creating websites and online stores since 2013. Design, development and marketing specialists join the project according to its needs, with one person leading the collaboration.
Krzysztof Samborski, the owner of Testin, is the contact for partnership conversations. Start by telling him about your agency and the development work your clients need.
Before the first project
Yes, delivery under your agency’s brand is an option. We agree the arrangement before work begins, including who leads the client relationship, whether any direct client contact is needed and how Testin’s work is presented.
A short introduction to your agency, the project goal and a public site or design link are enough for the first conversation. We then identify materials, dependencies and the access needed. Arrange credentials separately; keep them out of the contact form.
Yes. Share the layouts, assets and intended functionality. We review responsive states, editable content areas, interactions and integrations, then define the implementation scope and any design decisions still needed.
We review the brief and dependencies before preparing a proposal. It sets out the work, review stages, required materials and responsibilities. Timing depends on that scope and the project’s starting point; we confirm the schedule for the specific project.
If an NDA is part of your process, tell us before sharing confidential material. We can review it and agree suitable confidentiality terms, permissions and client communication before access or development begins.
Yes, we can plan maintenance, fixes and further development. We first review the website and agree the covered tasks, access, licence responsibilities and communication. Any response-time commitments are defined in the support agreement for that website.
Tell us about your agency, the design or website involved, and where you need development support. We will discuss the scope and how to work together.
