When it comes to deploying an employee directory and org charting solution, enterprise decision-makers face a familiar fork in the road: build it in-house, or buy from a proven SaaS provider. On the surface, building seems appealing — full control, no vendor dependency, tailored to your exact needs. In practice, the data tells a very different story.
The Numbers Don't Lie
Before diving into the case for buying, it's worth confronting the statistical reality of enterprise IT projects:
- 66% of enterprise IT projects exceed their budget (McKinsey & University of Oxford, 5,400+ projects)
- 45% average cost overrun on large IT initiatives
- 56% less value delivered versus initial predictions
- ~40% of IT projects fail to meet their deadline
These aren't outliers. They're the norm. And employee directory projects, often perceived as "simple" internal tools, are no exception.
What It Actually Costs to Build
Let's talk numbers. Custom enterprise software development typically runs $150,000 to $500,000+ for initial delivery alone, and that's before you account for the hidden costs that accumulate every year after launch.
McKinsey research shows that annual maintenance of custom software costs roughly 20% of the original development cost, every single year. Build a $300K solution today, and you're looking at $60K/year just to keep the lights on, before a single new feature is added.
Then consider the human side. Losing a developer mid-project costs over 100% of their annual salary in recruiting, onboarding, and productivity ramp-up. In a tight labor market, that's not a hypothetical risk, it's a near certainty over a multi-year build.
And every additional year a project runs increases cost overruns by approximately 15%. The longer you build, the more you bleed.
Time Is Money — And Building Takes a Lot of Both
End-to-end design, development, testing, and deployment for an enterprise-grade employee directory typically stretches 12 to 24 months, and that's the optimistic estimate, assuming no scope creep, no turnover, and no integration surprises.
With a solution like Sift, organizations go from contract signature to a live, scalable employee directory in a matter of weeks. That's not just a faster timeline, it's a fundamentally different business outcome: earlier onboarding experiences, faster productivity gains, and quicker return on investment.
Mobile support alone illustrates the complexity of building in-house. Supporting both iOS and Android natively means separate development tracks, ongoing certification cycles, and dedicated mobile QA resources. These aren't optional extras, they're table stakes for a modern workforce. Sift maintains fully certified mobile applications across both ecosystems and all major browsers, delivered as part of the base platform.
Risk: The Factor Most Teams Underestimate
A McKinsey and University of Oxford study of more than 5,400 IT projects found that 17% went so poorly they threatened the company's viability. For large projects with budgets exceeding $15M, the average cost overrun was 45%, while value delivered fell 56% short of forecasts.
The culprits are familiar to anyone who has run a large IT initiative: scope creep, shifting requirements, underestimated technical complexity, and developer turnover. When requirements change mid-project, a near-universal experience, costs can escalate by up to 50%.
When you partner with Sift, you're not managing a software project. You're activating a proven platform. The engineering, infrastructure, and product risk transfers to your vendor, not your team.
The Innovation Trap
Here's what most build-versus-buy analyses miss: the ongoing cost of staying current.
Technology doesn't stand still. An employee directory built today will require updates for new operating systems, new collaboration platforms, new data privacy regulations, and evolving workforce expectations. Internal teams routinely find that maintenance consumes 60–80% of available development capacity, leaving almost no bandwidth for innovation.
Sift continuously invests in platform enhancement on behalf of its entire customer base: new HR system integrations, advanced people analytics, org chart visualizations, AI-powered search, and emerging collaboration platform connectors. These improvements are delivered to your organization without requiring you to dedicate IT budget to keep pace.
Your engineers get to focus on work that creates competitive advantage, not on maintaining a commodity infrastructure tool.
What You're Actually Buying
Sift has been around since 2015, and invested over those years in building and continuously evolving a best-in-class people directory purpose-built for enterprise needs. By partnering with Sift, your organization leverages that investment at a fraction of what it would cost to replicate independently.
That investment buys more than software. It buys a proven onboarding methodology developed across hundreds of enterprise deployments, institutional knowledge your internal team would have to discover through trial and error. It buys enterprise-grade security maintained and updated by specialists. It buys pre-built integrations to leading HR platforms, rather than custom integration work for every system.
Build vs. Buy at a Glance
The Bottom Line
The data is unambiguous. Building an enterprise employee directory and organizational charting solution in-house is a high-risk, high-cost undertaking with a documented history of budget overruns, missed deadlines, and under-delivered value.
The organizations that choose to buy a solution like Sift, gain an immediate, scalable solution backed by $10M+ in platform investment, continuous innovation, proven adoption methodology, and enterprise security. More importantly, they free their engineering teams to focus on the work that truly differentiates their business.
The build-versus-buy decision is rarely as close as it looks on a whiteboard. The evidence says: buy.
