How we work with you
With our 20+ years of expertise, we have honed our technical authoring processes. We make it as simple as possible for you – no matter how complex your product or how tight your deadline is. Here’s an overview of our process:
Initial request
We understand what you want to achieve, recommend the way forward and provide an outline budget to get started.
Scoping
You share more details about your priority product and what you need to communicate. Our team creates a plan and detailed budget for you to review.
Authoring
We begin authoring the content and building your technical content, automating when we can. You provide some input and feedback on early prototypes, alongside our own QA processes.
Delivery
We complete your content and fine-tune the final formats for publishing. You confirm you are happy with your technical content, and then we make it ready to use.
Six reasons to work with us

1. We focus, so you can focus
Outsourcing to us allows your best people to remain focused on your core business, where their time is much better spent working on your products and with your customers. Technical writing is what we do every day, so we have lots of experience. We have the people, tools and processes ready to adapt and deploy for you. We already know how to turn your technical product content into a clear, trusted source of truth that’s AI-ready.
2. We’re quick, and accountable
Whether you need to meet a product launch or compliance deadline, or simply want to make it easier to deliver the right content with velocity, 3di has honed our services to support your goals. We typically start projects within 1-2 weeks of your decision, and commit to milestones, deadlines and a fixed budget. We have the flexibility to add and reduce resources to reflect your business needs, and we only invoice for services delivered to your satisfaction.
3. We deliver compliance, when it matters
If product compliance matters to you, then it matters to us. We have tools, templates and workflows that enable the quality assurance you’ll need, and we know how to adapt them to reflect your priorities. We’ll combine our experience across highly regulated industries with your detailed knowledge of your products to create documents and content that help, and protect both you and your customers.

4. Confidence that your information will work
Information design has underpinned the 3di approach to technical writing for over 20 years. Within our niche field, best practices have emerged over the years and 3di has become an expert at knowing how to combine and deploy these for our customers. We know, and have ready to adapt and deploy, the combinations of modular text, graphics, ilustrations, video, structures, navigation, metadata and layouts that will meet specific information needs, no matter what the context.
5. Documents that drive revenue
Your technical product documentation can be a powerful contributor to your content marketing and customer experience strategies. 3di turns documents you’re publishing because you have to, into documents that drive revenue, loyalty, brand reinforcement, and customer experience reputation. As a bonus, those same documents will reduce your own wasted time and effort, reduce your onboarding and support costs, and ensure you’re more AI-ready.
6. We can prove it
Our design expertise will ensure that we focus on creating the information you really need. After we publish your content, we use a range of techniques to check how it is being used. The more we understand about the impact of the content, the easier it will be to deliver the returns on investment you expect. As a result, our technical writers will be able to focus on the content that matters, and recommend what’s worth writing, translating and publishing.

FAQ’s
Who will work on my projects?
The individual 3di authors and translators who work on your content will understand your world, your audience and your priorities. Our diverse projects have more in common than they do differences. No matter what industry we work in, or what language we speak, as writers and readers, we all behave in very similar ways. For example, designing an award-winning knowledge base for our Saas customer has to consider very similar issues to designing award-winning API documentation for Unzer.

Can you work with my in-house technical writing staff?

We can seamlessly integrate with your existing team and flex our services as you have peaks and troughs in demand.
We’ve been working with companies around the world for over two decades, and can easily adapt to your organisation’s style, preferences and preferred tools. We also have experience in a variety of industries, and no subject matter is too niche or complex for our team. We can bring our tools, knowledge, industry expertise, and multi-disciplinary team to act as your external writing team, and give you access to extra resources and expertise when you need them.

Do you have the expertise to handle industry-specific technical writing projects?
In short, yes. The slightly longer answer is, our in-house technical writing team have experience in a variety of industries – we’ve handled all manner of projects, including documentation for autonomous robots and automated warehouses, product guides for marine electronic manufacturers, information portals for multi-national telecoms companies, API and developer documentation for software developers – we’ve even made documentation for very expensive and bespoke pens.
Any gaps in our knowledge can be filled by our extensive network of freelancers, who supplement our in-house technical writing team. We typically have long-standing relationships with our freelancers, some of whom have become members of our in-house team, and some of whom have been working with us since we started back in 2002.

Where is 3di’s technical writing team located?
Our in-house team of authors are split between our four offices, located in Woking and Edinburgh in the UK, Krakow in Poland, and Guadalajara in Mexico. The location of our offices means we can align with our customers’ time zones in the UK, the US and Europe. We’re normally delivering our services remotely, but we can work on-site with you if need be.
How do you ensure the quality of your services?
3di is BSI audited to ISO9001:2015 standards and a member of the ISTC (the Institute of Scientific and Technical Communicators). 3di has also won numerous awards for a variety of projects, which you can read about on our awards and accreditations page.
So delivering quality to meet customer expectations has been a habit for over 20 years. We combine industry best practices with our own expertise, tools and workflows to make sure that what you receive from us meets your expectations.
Each customer’s idea of quality can be quite different, but we take it as a good sign that nearly every customer works with us on multiple projects or over many years.
How much does an outsourced service cost?
Every project has different requirements, tooling, and authoring time. After discussing your project with you, we can provide you with accurate pricing figures. However, we are on average 20% cheaper than hiring an in-house technical writer. We also have the added advantage that we can flex to peaks and troughs in your demand. By using our services, you have access to our in-house expertise in the form of technical writers, content tools developers, project managers, and localization engineers, rather than a single technical writer.
