Should you build your own licensing system, or buy one?
Most software publishers ask this question at least once. Here's an honest breakdown of what each path actually involves — including when building in-house is the right call.
Not sure yet? Let's talk it throughTimeline
How long can you afford this to take?
Engineering bandwidth
Who owns this a year from now?
Total cost
Build cost is rarely the whole cost.
Environment fit
Does anything standard actually fit yours?
Every publisher eventually asks this
Licensing feels like it should be simple to build — issue a key, check it on startup, done. It rarely stays that way. What starts as a basic activation check tends to grow: entitlement tracking, renewal logic, offline validation, protection against tampering, reporting for compliance. Publishers who build in-house often don't hit the real cost of that growth until they're several years and several engineering-hours deep into maintaining something that was never meant to be a full-time product.
Build in-house, buy AuthGuru, or commission a custom build
Each path trades off differently on speed, cost, and long-term ownership. Most publishers land on one of these three once they see the tradeoffs side by side — here's what each actually involves.
Build In-House
For genuinely minimal needs, or teams with real bandwidth to own this indefinitely.
Weeks — but effort compounds as requirements grow.
Your engineering team, indefinitely.
Only if built for it from day one — often retrofitted later.
Ongoing engineering time — usually the real cost, not the initial build.
Full control.
Buy AuthGuru
Fits requirements that match standard licensing, protection, and deployment patterns — most publishers land here.
Fast — the platform is already built.
Bastion maintains and evolves the platform.
Yes, natively.
License/platform cost, ongoing.
Cloud, on-premise, or offline depending on configuration.
Custom Build (Bastion)
Reserved for requirements specific enough that no packaged platform — including AuthGuru — fits cleanly.
Longer — full requirements, design, and development cycle.
Bastion delivers and can support post-delivery.
Yes — this is the option built specifically for those cases.
Project-based engagement cost.
Internally hosted or customer-controlled deployment available.
None of these paths is inherently "better" — they solve different problems. The right one depends less on preference and more on how far your requirements sit from standard licensing patterns.
The build cost is the easy part to estimate
Most build-vs-buy comparisons stop at "how long to ship a first version." The cost that actually determines whether building was the right call shows up in the years after — and it's rarely the part anyone budgets for upfront.
What the estimate usually misses
A working first version is achievable in weeks. What's harder to estimate is everything that comes after it works — and whether your team can keep owning it as requirements change.
Requirements don't stay fixed
A second product line or an offline customer means revisiting decisions you thought were settled.
Ownership doesn't transfer easily
If the engineer who built it moves on, the knowledge often moves with them.
It competes with your actual product
Every hour spent maintaining licensing is an hour not spent on what you sell.
Sometimes, building it yourself is the right answer
If your licensing needs are genuinely simple — a single product, one commercial model, no offline requirement, no compliance pressure — a basic in-house check can be the right call, at least for now. The pattern worth watching for isn't "did we build vs. buy," it's what happens when requirements grow past that original scope: a second product line, a customer who needs offline support, an audit request the current system wasn't built to answer. That's usually the point where the in-house cost curve stops looking flat.
A real example, not a hypothetical
Standard platforms are built around common patterns. This engagement wasn't one — an embedded, Unix-based deployment with no room for a packaged licensing tool to work as designed.
Bastion has delivered a fully bespoke, internally hosted licensing system for a global security-technology provider, built for an embedded, Unix-based deployment — an environment a standard licensing platform would not have supported.
A global security-technology provider needed licensing for an embedded, Unix-based deployment — a business problem no packaged platform, including AuthGuru, was built to solve directly.
Embedded, Unix-based, and required to run on internally hosted infrastructure — with no dependency on Bastion-hosted services or a third party's uptime.
Bastion designed and delivered a fully bespoke system engineered specifically around this environment, not adapted from an existing licensing template.
A working licensing system in an environment where neither an in-house attempt nor a packaged platform was likely to hold up long-term.
AuthGuru standard, or a custom build — how to tell which
Once you've ruled out building in-house, the next question is which of these two fits. The signals below usually make it clear well before you talk to us.
AuthGuru fits when...
Most publishers land here — your needs map to patterns AuthGuru already supports out of the box.
- Your licensing model is perpetual, subscription, trial, floating, time-bound, or usage-based.
- Your deployment is cloud, on-premise, offline, or some combination of the three.
- Software key, hardware dongle, or cloud-based delivery covers how you need to reach customers.
- You'd rather implement a working platform than manage a multi-month build.
- You want ongoing maintenance handled by someone other than your own team.
A custom build fits when...
Less common, but a real category — not a fallback for when AuthGuru "almost" works.
- Your infrastructure or deployment environment is genuinely non-standard — legacy, embedded, or highly specialized.
- Your licensing logic doesn't map to any standard commercial model, even a flexible one.
- You need full control over hosting, with no dependency on a third party's infrastructure.
- No packaged platform you've evaluated — including AuthGuru — has fit cleanly.
- You're prepared for a longer engagement in exchange for a system built specifically around you.
Ask yourself these, honestly
If more than one of these sounds familiar, it's usually a sign the standard paths — build it yourself or buy an off-the-shelf platform — won't hold up the way you need them to.
- Does your deployment environment sound like an edge case every time you describe it to a vendor?
- Would "we'll build it ourselves" actually mean one engineer, part-time, indefinitely?
- Have you already tried fitting a standard platform and hit a wall it wasn't built for?
- Does "internally hosted, no third-party dependency" matter more to you than convenience?
