What an override can change
An override targets a product, a collection, or a tag, and adds extra processing days — a minimum and a maximum, e.g. +5 days for made-to-order items — on top of your global processing time, still respecting dispatch days and holidays.
Worked example: made-to-order products
- In your Shopify admin, tag the relevant products
made-to-order(Products → select → Add tag). - Open ShipsBy → Overrides.
- Applies to: Tag →
made-to-order. - Extra days: 5 (min) and 5 (max).
- Click Add override.
Result: a store with 1 processing day and 2–4 day transit shows regular items as arriving in roughly 3–5 days, while anything tagged made-to-order automatically shows a window about 5 business days later. New products get the behavior the moment you tag them — no per-product setup.
Priority: which rule wins?
When several overrides could apply to the same product, ShipsBy applies exactly one — the most specific:
| Priority | Rule type | Example |
|---|---|---|
| 1 (highest) | Product override | “Oak Dining Table” → +10 days |
| 2 | Collection override | “Furniture” → +2 days |
| 3 | Tag override | made-to-order → +5 days |
| 4 (fallback) | Global rule | Your base delivery rule |
If two overrides of the same type match (e.g. a product is in two overridden collections), the one with the longer resulting estimate wins — the honest choice, since under-promising beats over-promising.
Zones still apply. Overrides adjust processing; the visitor's zone still determines transit. A made-to-order +5 days item shipped to a 6–12 day zone shows both delays combined.
Good practices
- Prefer tags over per-product overrides — they scale as your catalog grows.
- Keep the list short. If more than a third of your catalog is overridden, your global rule is probably wrong — fix it in configuration instead.
- To check which rule wins for a given product, open its page on your storefront — the widget shows the final estimate.
