Custom build, or off the shelf? See which way your factors point.
The five factors that actually decide it — differentiation, market fit, integration, economics and your capacity to own it. A published rubric, an honest answer in both directions, and a branded PDF report for the decision meeting.
Your level, five-dimension profile and recommendations appear on screen the moment you finish — no email, and the branded PDF report is yours to keep.

The flow
How it works
01Answer quick multiple-choice questions about the capability, the market and your organization — options, not essays.
02Get a build-buy-or-hybrid recommendation and a five-factor profile showing which way each factor points.
03Keep the branded PDF report — and send it through if you want the build side of the answer given straight.
Every result is one recommendation and five factor scores — an example profile.
The framework
Five factors, scored in the open
Every answer carries zero to three points by the direction it points — lower toward buying, higher toward building. Three questions per factor give a factor score out of nine; the five dimensions together land on one of four recommendations. The rubric is published because a recommendation you can't inspect isn't worth trusting.
0–3 per answer→3 questions per dimension→dimension score out of 9→5 dimensions→your result out of 45
No gate. Full results on screen — email is never required to see them.
Nothing stored. Answers are scored in your browser and never leave this page unless you choose to send them.
No invented benchmarks. Every number derives from the published rubric and your own answers.
All five dimensions weigh equally in v1 — deliberately, until real-world results earn differentiated weights. Framework v1 · September 2026.
Whether this capability is part of how you win — or a commodity every competitor runs the same way.
Why this matters
The oldest rule in the decision still holds: build what differentiates you, buy what doesn't. Custom software earns its keep only where your way of doing things is worth encoding.
How much does this capability differentiate your business?
If a competitor used the exact same tool, would it matter?
How standard is the process this software would support?
02
Off-the-Shelf Fit
How well existing products actually cover the need — evaluated, not assumed — and how much customization a bought product would take.
Why this matters
The most expensive build is the one a mature product already solved; the most expensive buy is the one customized past recognition. Both mistakes start with skipping the honest market evaluation.
How well do existing products fit what you need?
How much would you have to customize a bought product?
What happens with the parts a product doesn't cover?
03
Integration & Data
How deeply this must weave into your systems and data, whether vendor APIs expose what you'd need, and how much the data model itself matters to you.
Why this matters
Integration is where bought software meets its limits: a product owns its data model and exposes what its vendor chose to expose. When the system must live inside your workflows and your data, ownership starts to pay.
How deeply must this weave into your existing systems?
How much does owning the data model and its portability matter?
Do vendor APIs cover what you'd need to connect?
04
Economics & Horizon
The shape of the economics, not the amounts: how licensing scales with your growth, how long you'll need the capability, and how much of the business it touches.
Why this matters
Buying is renting: the meter runs on seats and usage, forever, on a curve you don't control. Building is an asset with an upfront cost. Which shape wins is a function of horizon and scale — not of either sticker price.
How does per-seat or per-usage licensing behave against your growth?
How long will you need this capability?
How much of the business does it touch?
05
Capacity to Own
Whether you can specify what it should do, who would evolve and maintain a custom system, and whose roadmap you want to live on.
Why this matters
A custom build is a commitment to direct something: requirements at the start, evolution forever after. Teams that can't yet specify or steward a system get better results buying — for now — than building blind.
Could you specify exactly what it should do?
Who would evolve and maintain a custom system?
Whose roadmap do you want to live on?
What your score means
Buy It0–13 of 45
The factors agree: this is a solved, commodity capability with products that fit, light integration needs and a horizon that suits renting. Run a disciplined selection, configure within what the product is built for, and spend your build appetite where it differentiates you.
Buy and Configure14–24 of 45
A product can carry this — with real configuration and honest eyes on the gaps. The risk at this level is creeping customization: every fight with the product's grain is a signal you're building anyway, at retail. Set a customization budget up front and treat breaching it as new information.
Build the Core, Buy the Rest25–35 of 45
The classic hybrid, and where most mature stacks land: build the differentiating core — the workflow, model or experience competitors can't copy — and buy the commodity capabilities around it. The design work is drawing that boundary precisely; the discipline is defending it in both directions.
Build It36–45 of 45
Differentiation, poor market fit, deep integration, long-horizon economics and the capacity to own it — when these align, custom is not an indulgence but the honest reading of the situation. Specify it around the gaps that ruled products out, and hold the build to the business case that justified it.
FAQ
About this advisor
Short answers to what people ask before they take it — including the bias question, answered straight.
01When should you build software instead of buying it?
Build when the capability differentiates you, off-the-shelf fit is poor, deep integration or data ownership matters, licensing compounds against your growth, and you can own a roadmap. Buy when the process is commodity and a proven product fits — configuration is cheaper than construction for problems the market already solved.
02What does this advisor measure?
Five factors that decide build-versus-buy in practice: how much the capability differentiates you, how well existing products actually fit, how deeply it must integrate with your systems and data, how the economics behave over your horizon, and whether you can specify and own a custom system's direction.
03Isn't this advisor biased toward building?
We build custom software, so the skepticism is fair — and the answer is the published rubric: you can see exactly how every answer scores, "Buy It" is a real result with genuine guidance, and no prices appear anywhere. Recommending a build you don't need would cost us more than it earns.
04What is the build-the-core, buy-the-rest approach?
Most mature stacks land in the middle: build the core that differentiates you — the workflow, model or experience competitors can't copy — and buy the commodity capabilities around it, like billing, messaging or analytics. The advisor's middle levels describe exactly this split and where your answers place the line.
05Do I need to share my email address to see the results?
No. Your result, the five-factor breakdown and the recommendations appear on screen the moment you finish, and the branded PDF report generates locally in your browser. Contact details only come into it if you choose to send your results through to pressure-test the decision with our team.
06What should we do with the result?
Take the level as a hypothesis and test it against the factor that scored most decisively — that's usually where the real constraint lives. Then price both paths honestly before committing: vendor quotes for buy, a scoped conversation for build. Send your results through and we'll give you the build side straight.
Want the build side given straight?
Send your results through and we'll pressure-test them like a working session: what genuinely warrants custom work, what you should buy, and where the core-versus-edges line sits for your case. If buying wins, we'll say so.
