Custify + Younium

Integrate Younium with Custify to sync subscription and billing data

Younium is a subscription management and billing platform built for B2B SaaS companies to handle complex subscription models, invoicing, and revenue recognition. Finance and operations teams use Younium to manage the full subscription lifecycle, from activation through renewal and cancellation. The Custify integration pulls your Younium billing and subscription data directly into customer profiles, so your CS team can act on revenue signals without waiting for manual reports.

What can I do with Custify and Younium?

  • Segment customers based on subscription data such as MRR, billing frequency, or subscription status, and build targeted success plays for each tier.
  • Define lifecycle stages based on revenue signals and create tasks or alerts when changes like downgrades, cancellations, or failed payments are detected.
  • Build customer success playbooks triggered by billing events: for example, automate outreach when a subscription is about to expire or when an invoice becomes overdue.
  • Include subscription and revenue data in Custify health scores to get a more complete picture of account risk, not just product usage.
  • Get real-time notifications when subscriptions change, so your team can respond immediately to downgrades or cancellations instead of finding out at renewal.
  • Identify customers with overdue invoices using Custify segmentation, and trigger collections or outreach workflows automatically.

How does Younium work with Custify?

Custify connects to your Younium account using your Client ID and Secret Key, then imports subscription and billing data for each of your clients. Each Younium account is matched to the corresponding Custify company using a configurable matching strategy: by default, it matches on the Younium Account ID, but you can configure it to match on Account Number, Account Name, or any other company attribute.

From a connected Younium account, Custify syncs:

  • Monthly Recurring Revenue (MRR)
  • Subscription status (active, cancelled, expired, and more)
  • Next billing date and amount
  • Billing frequency
  • Count of due invoices and total amount due
  • Total income from paid invoices
  • Customer since date (first paid invoice)
  • Last subscription start and cancellation dates

Custify supports real-time updates via Younium webhooks. When a subscription changes in Younium: an upgrade, downgrade, cancellation, or renewal: Custify reflects it immediately.
