Billing presets

A preset is a named set of billing rules. Instead of configuring 7 separate policy knobs, you pick a preset that fits your business model and you’re done. You can always override individual settings afterward.

The five presets

SaaS-Standard

Recommended starting point. Immediate upgrades, downgrades at period end, 7-day grace, block changes while past due.

Lenient

For B2B or high-value customers where churn is costly. 14-day grace, no change restrictions.

Strict

For services where access is tightly tied to payment. 3-day grace, block all plan changes while past due.

Transfer-First

For customer bases that primarily pay by bank transfer. 21-day grace window, very lenient dunning.

Postpaid / Arrears

Arrears billing mode, 14-day grace. For enterprise contracts and usage-based models.

  -d '{ "cancel_policy": "immediate", "grace_days": 3 }'

After applying

The preset updates your TenantPolicy. Existing subscriptions aren’t affected retroactively — only new billing cycles apply the new rules. If you need to change behaviour for an in-flight subscription, contact support or use a per-subscription override.
