Ask SIA for a recommendationBuying Guide
A practical framework for choosing — and switching — with confidence.
Start from your non-negotiables — the workflows, integrations and compliance ONNX must replace. Score each alternative on features, ratings, pricing and switchability, then shortlist the top two or three.
Ask about data import/export, contract length and auto-renewal, onboarding support, SLAs, and which features are add-ons versus included in the base plan.
Map your data model and integrations before moving. Alternatives that share integrations with ONNX (see each switchability score) are typically fastest to adopt with the least disruption.
Look past list price: factor in onboarding, training, data migration, and per-seat scaling. A free plan or trial lets you validate fit before committing budget.
Negotiate on annual commitments, seat tiers and bundled add-ons. Confirm price-lock terms and the cost of exiting before you sign.
If AI matters, verify the features are native (not roadmap), how they handle your data, and whether they're included or premium. The matrix above flags which alternatives ship AI today.
