Adopting a SaaS product is easy, which is the trap: the real cost of a vendor arrives later, in pricing surprises, integration lock-in, and the discovery at cancellation time that your data lives in their formats. An hour of diligence before signing prevents most of it.
Interrogate beyond the demo
- Data portability: can you export everything, in a usable format, through an API and not just a support ticket? Run the export during the trial.
- Security posture: SOC 2 or equivalent, SSO support without an enterprise ransom, and a breach history you looked up rather than asked about.
- Reliability: a public status page with honest history, an SLA with teeth, and support response times in the contract, not the sales deck.
- Roadmap dependence: if your use case needs a promised feature, it does not exist until it ships.
Read pricing like an adversary
Per-seat pricing punishes growth; per-usage pricing punishes success; tier cliffs punish the month you finally scale. Model the cost at three times your current size before committing, and watch for the classics: charges for API access, for SSO, for exports, and renewal increases with no cap. Multi-year discounts are fine once a vendor has earned a year of trust, and rarely before.
Plan the exit while entering
Before rollout, write down what leaving would take: what data comes out, what integrations get rebuilt, who owns the migration. Prefer vendors built on open standards where switching is plausible, and keep a copy of critical data syncing to storage you control. Vendors with graceful exits tend to be the ones you never need to leave, because the same respect for customers shows up everywhere else in the product.
