Weather

Does Weather hold shipments or add tags when it is too cold?

No. Weather attaches a forecast to matching shipments and shows it on the shipment, timeline, and documents. Deciding what to do (heat pack, hold, upgrade service) stays with the packer. Rules decide which shipments get a forecast, not what the weather must be. See Weather.

Do I need an API key?

Not with Open-Meteo (the default). OpenWeatherMap, WeatherAPI.com, and Visual Crossing need a key from your account with them.

No forecast appears on new shipments

Check Enable Weather and Auto-fetch in Settings, and that an enabled rule matches the shipment (a rule with no conditions matches everything). Manual refresh from the shipment card works even without a matching rule.

Can I print the forecast on the packing slip?

Yes — the default packing slip and Local Pickup Slip already show low / high. Add more with Insert variable in Documents, including addresses.<key> for your named addresses.

Rate Shopper

Which carriers does it compare?

Every active carrier account on the store. With one carrier there is nothing to compare — connect a second.

What does "savings" measure?

The difference between the winning rate and what your Default carrier (for savings) would have charged, recorded on every comparison. Set the default carrier in Rate Shopper Settings.

Where are the Boxes and Packing Materials pages?

They open Advanced → Packing Materials — one catalog shared by Rate Shopper, the shipment Packing card, and Reports.

Some shipments should always go with one carrier

Add a Rule with the condition (SKU, tag, destination, …) and restrict Eligible carriers & services. See Rate Shopper.

Shipping Rates

Checkout shows no shipping options

Make sure the Shopify Carrier Service is Activated under Shipping Rates → Settings, the profile is Active, a Default profile rule exists, and the profile has a Default zone. Turn on Fall back to Shopify backup rates on error as a safety net. See Shipping Rates.

Rates in the tester differ from live checkout

Check profile rules — a Schedule or Condition rule may pick a different profile live. Discounts also matter: Apply Discounts to Free-Shipping Thresholds changes which tier applies.

What is "Add to Existing Order"?

A checkout option that lets a returning customer add items to an order you have not shipped yet, waiving shipping. Configure it in the profile's Settings.

Delivery Calendar

How do I block a holiday?

Exceptional Days → add the date → Disable Delivery. Recurring closures use a weekday exception. See Delivery Calendar.

Can customers change their delivery date?

Yes, from their customer account when the extension is installed. Lock Changes Before Delivery and Maximum Date Changes limit it. A date the calendar would not have offered raises the alert Delivery date not offered by calendar.

The Orders calendar counts shipments, not orders

That is the Calendar Source setting on the calendar's Basic tab — switch it to Orders or Shipments as you prefer.

Inventory Management

Does it manage stock levels or alert on low stock?

No. It keeps local products, variants, and quantities in sync from Shopify via webhooks, polling, and Sync now. Stock adjustments still happen in Shopify. See Inventory Management.

Sync history shows a failed run

Open the run's Error. Authentication errors mean the store needs reconnecting under Integration → Stores.

Upsells & Add-Ons

Offers are enabled but nothing shows on the storefront

The theme and checkout blocks must be added — follow Set up in your store on the app page (Add in theme editor, Enable in theme editor, Open checkout editor). See Upsells and Add-On Products.

Where are upsell analytics?

Apps → Upsells → Analytics — impressions, click-through, conversion, revenue, RPM, with breakdowns and CSV. They need the View upsells permission, not the Reports permission.
