What an XR prototype quote should include

An XR prototype quote should describe a testable delivery, not a hopeful lump sum.

I wrote this because one vague line can hide several weeks of unpriced work. A careful quote also helps creators and clients discuss the same prototype before production begins.

What's the problem?

XR means extended reality, the umbrella term covering virtual and augmented reality. Its prototypes combine software, physical devices and people moving through real spaces.

That combination makes a fixed price harder than it first appears.

A quote might promise an "interactive VR prototype" without naming the headset. It may exclude device hire, shipping, controllers, chargers, account setup or a suitable computer. Each omission can become an urgent purchase later.

"Build delivery" is another slippery phrase. A build is the version of the experience you can install and run. The quote should say which platform it supports, how it will be delivered and whether source files are included. An installable headset application is different from an editable Unity project.

Testing also gets compressed into words like "quality assurance". That could mean one developer checking whether the application opens. It could also mean testing with representative users, recording failures and preparing a findings report. Those are different jobs.

Documentation and feedback often disappear entirely. Without a setup guide, known-issues list and review schedule, the prototype may work only while its original developer is in the room. (Developers do occasionally enjoy sleep.)

What's the solution?

Ask for five named sections before approving the price.

First, hardware. The quote should list supported devices and who supplies them. Check quantities, delivery costs, accessories and replacement arrangements. If the prototype needs a powerful computer or tracked room, that belongs here too.

Second, build delivery. Name the headset, operating system and delivery format. State whether you receive an installable build, source project, media files or all three. Include a delivery date and simple acceptance checks, such as launching successfully and completing the main interaction.

Third, testing. Record which devices will be tested and who will participate. Separate technical testing from user testing. Technical testing finds crashes, tracking errors and performance problems. User testing checks whether people understand what to do.

Fourth, documentation. A useful handover usually includes installation steps, controls, known issues and reset instructions. Add the test script and findings if research is part of the work.

Fifth, review rounds. A review round is one collected set of feedback followed by agreed changes. The quote should state how many rounds are included, when feedback is due and who combines comments. Ten separate emails should not quietly become ten review rounds.

Consider a prototype quoted for a standalone Meta Quest headset. If the client later expects a PC-connected version with higher-detail graphics, the delivery platform has changed. New optimisation, testing and hardware may be required. Naming the target device early prevents that disagreement.

Our work as the official virtual festival venue for Venice Immersive since 2024 has reinforced a plain lesson: delivery conditions are part of the experience. A prototype cannot be judged properly if nobody knows how to install, run or reset it.

What's next?

1. Mark every vague noun in your current quote, including "hardware", "testing" and "handover". Ask what each one contains.
2. Write five acceptance checks that someone outside the production team can perform without guessing.
3. Confirm the review count, feedback deadline and day rate for work beyond the agreed scope.

Share the quote checklist you use, or ask me about a line you cannot price clearly.
