The honest verdict

Where each one wins

Where Gradelink is strong

Excellent, easy-to-use gradebook and report cards
Fast setup with strong support — beloved by small-school registrars
Very affordable entry price for academics

Where 613OS wins

Gradelink's billing is basic invoicing — no dunning automation, zero-cost processing, or payment economics

No marketing suite, landing pages, review management, or AI assistant
613OS is the revenue layer Gradelink schools are missing — the two together cost less than FACTS alone

Our honest recommendation

Choose Gradelink for academics — genuinely, it's excellent at what it does. It's the SIS we most often recommend running alongside 613OS: they take the gradebook, we take every dollar and every family relationship.

This comparison is based on publicly available information and is provided for general guidance; features and pricing change frequently — verify details directly with each vendor. 613OS is not affiliated with or endorsed by any company mentioned. Where 613OS lacks a capability (such as gradebooks and academic records), we say so and recommend an SIS integration.
