SEIDO vs Rentio
✓ SEIDO is a better choice if you are an agency of 50+ units with a multi-collaborator team and need to centralise incoming channels.
→ Rentio is a better choice if you are an independent landlord or small agency (< 50 units) focused on tenant portal and application management.
= Both offer a modern tenant portal. The choice depends on your team size and operational complexity.

When Rentio is a good choice
You are an independent landlord or agency with fewer than 50 units with simple flows.
You recruit new tenants regularly and the application workflow (screening, viewing, lease) is your main use case.
Your portfolio is mainly in Flanders or the Netherlands, Rentio is strong in these markets.
When SEIDO is a better fit
Your portfolio exceeds 50 units and several collaborators must coordinate interventions.
Requests arrive via multiple channels (WhatsApp, email, phone) that you want to centralise.
You need AI triage to automatically qualify requests and a structured contractor portal.
