Passmundi Reseller

Passmundi Reseller lets hosting companies, web agencies and IT providers sell Passmundi email protection from their own WHMCS. Passmundi filters spam, viruses, phishing and spoofing before mail reaches the mailbox, by changing the domain's MX records. Your clients keep their current mailboxes and email provider.

The package contains two modules that work together.

Addon module

Dashboard: active services, protected mailboxes, monthly revenue, Passmundi cost, margin and margin rate, and a to-do list (price changes, services sold at a loss, mailboxes protected but not billed, services not found).
Plans and margins: every Passmundi plan with your cost, the recommended price, your selling price and your margin.
Margin calculator: exact Passmundi price for any number of mailboxes, with your margin and a table from 1 to 100 mailboxes.
One-click WHMCS products: name, group, description, price per mailbox, steps or fixed packs, all billing cycles, options included or configurable, rounding, and a preview of every price in every currency before creation.
Price updates: products to update are flagged when Passmundi changes its prices, with a side-by-side comparison, or automatic updates.
Services: client, domain, mailboxes protected and billed, revenue, cost, margin and alerts, with filters, search and CSV export.

Provisioning module

Create, suspend, unsuspend, terminate, upgrade and downgrade Passmundi accounts.
Single sign-on to the Passmundi space from the client area and the admin area.
Domain setup steps shown to the client: TXT verification, MX records and the SPF record to publish, with copy buttons.
Service overview in the admin area: status, plan, protected mailboxes, messages analysed, domains and DNS records.
Daily sync of the mailbox quantity, import of existing accounts, usage billing metric.

Billing models

Resale: Passmundi bills you at your reseller price, and your clients never see your prices.
Commission: Passmundi bills your clients at the public price, and you earn a commission on each paid invoice.

Sandbox

A Production / Sandbox switch lets you test in your production WHMCS with a test key. Demo accounts are never billed and your real clients are not affected.

Languages

The admin area and client area are in 9 languages: English, French, German, Italian, Spanish, Portuguese (Portugal and Brazil), Dutch and Polish.
