Frequently Asked Questions

Common questions about Precision Live Rates for WooCommerce

Sign up at https://dashboard.shipengine.com/ — the free sandbox tier returns synthetic rates that work end-to-end for testing. Once you're ready for production, the same dashboard issues LIVE_… keys; connect at least one carrier (USPS via Stamps.com Connect is free and the easiest start) under ShipStation/ShipEngine → Settings → Shipping → Carriers, then paste the key into Precision Live Rates → Settings → ShipEngine. The Test Connection button below the key field pings /v1/carriers and lists everything connected — use it to confirm the key authenticates before going live.

ShipEngine returns each carrier's account/negotiated rate. For UPS specifically, that's typically 30-50% below ups.com retail (UPS heavily discounts via aggregators to compete with USPS). To display retail-equivalent prices to customers, set the UPS markup % under Precision Live Rates → Settings → Markup. 65-75% bridges the gap for most accounts; check a few real shipments via the Rate Test tab to calibrate. USPS rates from ShipEngine already match retail — leave the USPS markup at 0.

Yes. Under Settings → UPS direct or USPS direct, paste your client ID + client secret. The plugin uses OAuth 2.0 client-credentials flows for both carriers. Sandbox and production toggle with a single checkbox. You can run UPS direct + USPS direct + ShipEngine simultaneously — rates from all three sources merge into a single deduped list at checkout.

Trigger at least one rate quote (open the cart with a shippable address). Then visit Precision Live Rates → Services. Every carrier:service_code the plugin has seen is listed as a checkbox. Uncheck what you don't want, save. The change applies to the very next cart view — the plugin auto-flushes WC's shipping cache on save. If a service still shows up after saving, the cause is almost always a downstream cache (Varnish, Breeze, browser, CDN) serving a stale checkout page; the diagnostic count at the top of the Services screen tells you whether the save itself persisted.

Default on. When no box catalog is configured, the plugin can either ship each cart line as its own parcel (carriers bill each one — 4 mugs = 4 UPS labels = 4× the cost), or aggregate the cart into one representative parcel by stacking items along their smallest dimension. The default "combine" behavior is what most small shops want; toggle off under Settings → Packing if you genuinely need strict per-item billing. Once you configure a box catalog under Precision Live Rates → Boxes, items pack into real boxes regardless of this setting.

A few possibilities. (1) The plugin's own rate cache. Default TTL is 60 seconds; click "Clear cached rates now" on Overview → Quick actions to bust it immediately. (2) WC's shipping transient. Auto-flushed on every settings save, but if you saved via raw update_option() the auto-flush didn't fire — clear from Overview. (3) Editing a product's weight/dimensions/shipping class auto-invalidates the rate cache, so 0.2.2+ shouldn't have this issue from product edits. (4) Downstream cache (Cloudways Varnish, Breeze, browser, CDN) serving stale checkout HTML. The Services tab's diagnostic count distinguishes "save didn't persist" from "downstream cache is stale."

It returns whatever the carrier returns for international destinations. The plugin's address-fallback logic currently optimizes for US ZIPs (auto-derives state from ZIP when the customer leaves it blank); other countries pass through. There is no separate customs declaration workflow yet — declared values and dimensions pass through to the carrier; carriers handle customs ingestion. Canadian and UK postal-code → province/region inference is on the roadmap (BACKLOG E4).
