White-label plugin development: how AEC software vendors add engineering capacity
Zakhar Vityk, CEO, Consedge Tech
Most AEC software vendors and BIM consultancies reach the same wall. The roadmap is bigger than the team. Hiring a developer who knows the Revit API takes months. A general outsourcing firm can write C#, but does not know why a workshared model behaves differently from a sample file.
White-label plugin development is the third option: a specialist team builds under your brand, and your client deals only with you. This article explains how that works in practice, what to check in a partner, and how to start without betting a product on it.
What white-label development means
The product carries your name. The client relationship, the price and the roadmap stay with you. The engineering is done by a partner who stays invisible.
In AEC software that usually means one of four things:
- a new add-in for Revit, Tekla, AutoCAD, SolidWorks or Siemens NX,
- a module added to a product you already sell,
- an integration between a desktop tool and a web platform,
- maintenance: keeping an existing add-in working as the host software changes.
Who uses it
Software vendors. A company with a strong web product needs a Revit add-in. A Revit vendor gets asked for Tekla. The core team is excellent at what it does and has no time to learn a second platform.
BIM consultancies and resellers. Clients ask for custom tools. The consultancy knows the workflow in detail and has no development team.
Prime contractors and software houses. A larger project includes a CAD or BIM component that the in-house developers have never touched.
The trigger is often a date. A new Revit release arrives, a customer upgrades, and an add-in stops loading. This year the pressure is higher than usual, as our guide to Revit add-ins on .NET 10 explains.
How an engagement runs
- NDA first. No repository access and no client data before a mutual NDA is signed by both sides.
- Technical discovery. A short review of the idea, the existing code and the risky parts of the API. The result is a written scope with every assumption stated.
- Fixed scope per milestone, or agreed monthly capacity. You know what each stage delivers before it starts.
- Weekly builds. You test real software every week, not a status report.
- Release under your brand. Installer, documentation and release notes carry your name. Your team presents the result to your client.
- Maintenance. New host versions, bug fixes and second-line support behind your own first line.
Everything before the release stays between your team and ours; the client meets the result only under your name.
Who does what
| The engineering partner | You |
|---|---|
| Architecture and development | Client relationship and commercial terms with the client |
| Testing, installers, documentation | Product decisions and priorities |
| Updates for new software versions | First-line support and sales |
| Technical advice during pre-sales, behind the scenes | The brand on everything the client sees |
Seven questions to ask a white-label partner
- Have you shipped and maintained your own product on this platform? Building a demo and supporting a product for years are different skills.
- What do you do when a new Revit or Tekla version is released? Ask for the process, not for reassurance.
- Who will write our code? Ask about seniority, and whether your engineers will talk to theirs directly.
- How do you treat our code and our clients' data? Access rules, NDA, where repositories live.
- How is scope fixed, and how are changes priced? Vague scope is where partnerships sour.
- What does handover include? Could your own team, or another vendor, take the code over?
- Can you stay invisible? Emails, documents, installers and commit history should never surprise your client.
How to start small
Nobody should hand a core product to a new partner on day one. Three starting points carry little risk and show a lot:
- One module. A single feature with a clear boundary.
- A version migration. Moving an existing add-in to the current host release shows how a team reads code it did not write.
- A review of an existing add-in. A written assessment of what it needs to be maintainable.
Many of our partnerships began with one of these.
How we work with partners
Most of Consedge Tech's work comes through partners: software companies, BIM consultancies and resellers. We build for Revit, Tekla, Siemens NX, SolidWorks and Autodesk Platform Services, and we maintain our own products, including Views for Revit and Collision Manager. That is how we know what shipping and supporting an add-in involves.
The team is small by design and senior. Your engineers talk to the people who write the code.
The partner page describes the model. To test it on a real task, book a Feasibility Review. You get a written verdict on feasibility, risks and what production will involve. Our plugin development page lists the platforms we cover.
FAQ
Will our clients know that a partner built the software?
No. The work is done under NDA and delivered under your brand.
Can we start with a small task?
Yes. One module, a version migration or a code review are the usual first steps.
Do you handle long-term maintenance?
Yes. Updates for new versions of the host software and bug fixes are part of the partnership.
Which platforms can a white-label partner cover?
In our case: Revit, Tekla Structures, AutoCAD, SolidWorks, Siemens NX, Autodesk Platform Services and web applications around them.
Working on something like this?
Thirty minutes with the engineers who would build it, then a written verdict — including “don’t build this” where that is the answer.
