Eternitie is the alumni and rush platform. Dueflow is the chapter’s finance system, at $0.
Eternitie (eternitie.app) calls itself 'the operating system for Greek life': a self-updating alumni directory enriched from LinkedIn and public professional data, mentorship matching between actives and alumni, a rush pipeline (PNM profiles, ratings, votes, bid lists), alumni donations and giving campaigns, and chapter-wide email and SMS, each chapter on its own branded subdomain. Dues appear on its fraternity page as one line next to donations, and no price is published anywhere on the site. Dueflow is built for the treasurer: dues with payment plans and partial payments, reminders that stop when a member pays, reimbursements, budgeting with bank sync, a merch and ticket store, QuickBooks sync, Form 990 filing, and a free nationals dashboard, at a published $0 platform fee.
Dueflow is free for chapters and nationals – $0 platform fees forever. Members pay a small processing fee per payment.

Chapters and nationals running on Dueflow.
A quote-only alumni platform vs. a published $0.
Eternitie publishes no price: eternitie.app has no pricing page and none of its product pages states a platform, per-member, or processing fee, so this page shows no Eternitie dollar figure and none should be inferred. Dueflow's price is on its pricing page: chapters and nationals pay $0, members pay a flat processing fee only when they pay, and a chapter can sign up and send its first dues request without a sales call.

*Eternitie publishes no pricing on eternitie.app (checked October 2026: no pricing page, no fee stated on the Greek life, fraternity, or sorority pages, or in its llms.txt), so no dollar figure is shown. Hours are estimates: Eternitie provisions a branded per-chapter workspace and imports the roster and alumni list; Dueflow chapters typically send their first dues request within 5 minutes of signing up.
When to choose Dueflow, and when Eternitie may fit.

Choose Dueflow if the treasurer's books are the problem
Dues with payment plans, reimbursements, budgets, bank sync, QuickBooks, a store, fundraising, and Form 990 filing at $0 for the chapter, live the same day. The next treasurer inherits one set of books instead of a Venmo history.
No demo request and no quote: the member processing fee is on the pricing page and the chapter pays $0. Nationals join the oversight dashboard at $0 too.
Eternitie may fit if the alumni network is the problem
If what your chapter needs is a directory that keeps alumni employers and cities current, mentorship matching, rush pipelines, and giving campaigns in one branded workspace, that is what Eternitie is built around; many chapters run it next to a dedicated dues tool.
When you need a hand – a question at 11pm, a fix before dues go out – you get real people who answer fast. Support, engineers, and operators who actually build for you, not a ticket queue.

Every chapter finance job in one login.
Eternitie gives a chapter a living alumni directory, mentorship, rush, giving campaigns, and communications, with dues as one line of the 'donations, dues, and giving' feature. Dueflow covers the money side end to end for the chapter and its nationals: dues, payment plans, reimbursements, budgets, bank sync, store, fundraising, accounting sync, and tax filing.

Built for the treasurer
Dues, reimbursements, and budgets in the same books.
Eternitie's fraternity page describes collecting dues from actives alongside alumni donations. Dueflow is run by the chapter treasurer: members pay through the portal with a plan if they need one, reimbursements are approved from a receipt photo, and every dollar lands in a budget bucket.
Eternitie does not publish how members pay or what it costs. Dueflow publishes the fee per method on /pricing, adds Klarna buy-now-pay-later and partial payments at the member's own pace, and the chapter's platform fee is $0.
Eternitie lists national offices as an audience but describes no HQ finance view on its public pages. Dueflow's nationals dashboard shows per-chapter collected, outstanding, and overdue at $0, so chapters keep their own books and HQ keeps oversight.

We're biased – Dueflow wrote this page. Every Eternitie claim above comes from eternitie.app (the homepage, /greek-life-software, /fraternity-software, /sorority-software, and /llms.txt) as reviewed in October 2026; where Eternitie's site does not mention a feature or a price we say 'not listed' rather than 'not offered'. Spot something outdated? Email hello@dueflow.co and we'll fix it.
