1. The Shopify ceiling
Shopify — not the app — allows each store:
- 25 active payment customization functions
- 25 active delivery customization functions
Both count across every installed app. Another checkout app may already be consuming part of the allowance.
Fix: deactivate rules you no longer need, or consolidate. One hide rule can name several methods, and one condition using Is one of often replaces three near-identical rules.
2. Your plan’s rule limit
Separately from Shopify, your plan can cap how many rules you create. The cap applies per method type — a limit of five means five payment rules and five shipping rules, not five in total.
Plan limits come from billing, not the app
Rule and condition limits are configured per plan rather than fixed in the app, so what you see depends on your subscription. The editor shows your remaining allowance as you build.
3. The action is not on your plan
Hide, rename and reorder are enabled independently for payment and shipping — six separate capabilities. A locked action shows a lock icon and an upgrade prompt rather than an error.
4. Conditions per rule
There is a cap on conditions in a single rule, and Cart attribute is separately capped at two. The Add Condition modal shows how many slots you have left, so check there rather than assuming a number.
If you have hit it, split the logic across two rules — they stack.
Still stuck
Send support the rule name, a screenshot of the editor, and how many active rules the store has. The customization ceiling is the usual answer and is quick to confirm.
