Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Avalara

Pricing varies significantly based on products, integrations, transaction volume, and jurisdictions
No free tier or trial period published
Enterprise sales model requires contacting sales specialists for customized quotes

Omnea

It covers intake through contract only, so invoicing, payment and spend analysis remain with other systems and the promised end-to-end view is partial.
As a younger vendor its integration library is narrower than the established suites, and connections into older on-premise ERP systems may require custom work.
Pricing is entirely quoted with no published tiers, and the vendor is small enough that comparable public reference points are scarce.
Third-party risk depth is good for questionnaire-driven assessment but lighter than a dedicated GRC platform on continuous monitoring and control mapping, so heavily regulated firms may still need both.
Its value is concentrated in organisations with a formal procurement policy and a compliance obligation; a company without either gets an approval workflow tool at enterprise pricing.
