I worked with Thoughtprocess Interactive (TPI) on the design and development of a new site for a large non-profit organization. We came to TPI with a sitemap and wireframes and they improved upon and helped us implement our plans. TPI took time to understand our organization, in addition to the goals and target audiences for our site. They designed a custom WordPress site that aligned with our brand beautifully and really elevated our web presence. As the client, it was a joy to partner with TPI. They respected our brand assets and content while making thoughtful suggestions as we populated our site. The team at TPI is made up of technical specialists who are down-to-earth and exceptionally kind. The expert and professional James and Scott started us off, then Vicki was assigned to manage our project. Vicki is reliable, responsive, and talented. She effectively engaged Nichole and Sonny, who brought their diverse skills to the table while keeping things moving swiftly on our ambitious timeline. Tami handled our billing and was always a pleasure to correspond with. James leads TPI but still managed to do a lot of nitty gritty design and development work at the beginning of our project, then remained in the loop with Scott as things progressed – very impressive and unique. I’ve been in the marketing and communications space for most of my career and as a result, have worked with several technical consultants. TPI was by far the most talented and well-rounded – I’m very grateful to their entire team!

Our company has been working with Thoughtprocess Interactive (TPI) for several years on digital marketing projects and they recently assisted us with a website redesign. We are very happy with the results and I was impressed with TPI's ability to listen to our needs and vision and translate that into a beautiful, functional website that better speaks to our customer. Specifically our account manager, Vicki, was a pleasure to work with and really came through organizing work flow and always being available for questions. We look forward to continuing our relationship with TPI to further develop SEO strategy.

Web Design Questions We Hear Often

Do you build on a specific platform, or can you work with what we already have?

We’re definitely not tied to any specific platform or CMS, we’ve worked with all kinds! We’re partial to WordPress for its scalability and flexibility but have done custom designs in other platforms like Magento, Shopify, Squarespace and other more custom CMS systems. If you already have a platform you know and love, that’s great! We’ve probably worked with it already and if not, we’re happy to learn its complexities.

What does your design process look like?

Every project is a little different, but the process generally follows the same arc. It starts with understanding your business and your audience. We consider who’s coming to the site and what they need to do when they get there. If you have an existing site, that becomes a useful reference point for identifying what’s working and what needs to change.

From there, we get into design. We start by either building out a visual direction with new typography and color, or working within your existing brand standards. Rather than designing every page at once, we start with one key page for you to review and sign off on, then use that as the foundation for the rest of the site. That way there are no big surprises along the way.

How do you approach accessibility?

Accessibility isn’t a checklist item at the end of a project, it’s built into the design process from the start. At a baseline, that means legible typography and colors that meet contrast requirements. Depending on the scope of the project, it can go further: restructuring navigation for keyboard and tab usability, writing content in plain and approachable language, and making sure the site holds up for users who rely on assistive technologies. Accessibility is a wide spectrum, and how deep we go depends on your audience and requirements — but the fundamentals are always there.

What’s your approach to brand consistency across the site?

We start with understanding how you want your brand to come across. Get a good sense for the tone, the feel, the impression a visitor should walk away with. From there, we either establish brand standards if they don’t exist yet, or work within the ones you already have. That means being precise with typography and color usage and extending that same intentionality to supporting elements like iconography and imagery so everything feels cohesive rather than pieced together.

Do you offer post-launch support, and what does that include?

You betcha. We would never launch a site and leave you high and dry. We’ll make sure you know how to use your site to make updates and additions, and walk you through site care. If all of that sounds like too much to take on, we offer maintenance contracts to keep your site tidy and up-to-date on a regular basis and even manage your content updates if you like. Just let us know the level of support you prefer and we’re happy to make it so.

What information do you need from us to write an accurate proposal?

First, the we start basic. Is this a redesign or a ground-up build, and what is the site’s primary purpose? Whether it’s generating leads, driving e-commerce, or simply giving prospects a place to validate your business shapes a lot of decisions early on.

From there, scope questions: how many pages are you working with, and will the site include a blog or any specialized functionality like user accounts, appointment scheduling, a product catalog, or a project portfolio? These details can significantly move the needle on complexity and cost.

It’s also useful to know how design-intensive you’re envisioning the site to be — think of it on a scale of one to ten, where one is clean and straightforward and ten is rich with animations, video, and interactive details.

On the technical side, it helps to know if the site needs to talk to any external systems like a CRM, ERP, inventory software, or a job board. And who will be managing content after launch? That often influences which platform makes the most sense.

Finally, a couple of questions that don’t always come up but really matter: what does a successful visit look like? Is it a form submission, a purchase, a phone call? And how do you expect people to find the site, and how important is ranking for non-branded search terms? That tells us a lot about where SEO fits into the overall scope.

It might feel like a lot to think about, but getting aligned on these things early is what keeps a project on track and on budget. The more we can talk through upfront, the smoother the project goes.
