Should you build custom AI agents or buy off-the-shelf? Honest tradeoff analysis - cost, capability, ownership, lock-in. With real numbers from real deployments.

Off-the-shelf AI tools are cheap and fast. Custom builds are slower and pricier but yours forever. The right answer depends on workflow specificity, data sensitivity, integration depth, and competitive moat. Here's our framework.
Decision framework based on real deployments
When generic tools fit your need.
When workflow specificity demands it.
Best of both - custom on managed infrastructure.
Questions to answer before deciding.
Build vs buy across common workflows
SaaS $200-$2000/mo, Build $8K-$25K + $400/mo
Tier 1 support automation
Comparison analysis
SaaS $100-$500/mo, Build $5K-$25K + $300/mo
Inbound voice agent for service businesses
Comparison analysis
SaaS $30-$200/mo (Zapier+OpenAI), Build $4K-$15K + $200/mo
Multi-step business workflows
Comparison analysis
When the workflow is core to your competitive position, when off-shelf tools genuinely can't integrate with your systems, when data sensitivity requires control, or when long-term cost (3+ years) tips the math.
Typical range $5K-$50K initial build + $200-$2000/month for maintenance and AI usage. Depends on complexity, integration depth, ongoing scope.
Common pattern. Buy to validate the workflow, build once ROI is proven and the off-shelf tool hits limits. Most clients we build for tried 1-2 SaaS options first.
Big risk with build-on-platform approach. We architect for model-portability so you can swap providers if needed. Avoid deep lock-in to any single AI vendor.
