Common Lightspeed K-Series problems and how to fix them. If you're still stuck, [contact storekit support](/docs/getting-started/contact-support). Orders failing with **"Not processed before validity ended"**, **"K-Series iPad App is off"** or **"All active devices are offline"** all mean the same thing — the Lightspeed Active Device wasn't online. That has its own page: [Orders Failing: Till Offline](/docs/guides/integrations/pos/lightspeed/till-offline). ## Connection ### "Lightspeed K-Series" isn't in my Integrations list The integration isn't enabled for your account. [Contact support](/docs/getting-started/contact-support) to have it turned on. ### Orders fail with "Our access to your Lightspeed account has been disabled" Lightspeed is rejecting storekit's access. The integration user in Lightspeed has usually been disabled or had its permissions changed — re-enable it in the Lightspeed back office, then click **Disconnect Auth** and **Connect to Lightspeed** again on **Stores** → your store → **Settings** → **Integrations** → **Lightspeed K-Series**. ### I connected the wrong Lightspeed location Click **Disconnect Auth**, then **Connect to Lightspeed**, and pick the right location on the **Select your Lightspeed location:** screen. ## Menu Sync ### There's no Sync button on the menu The **Connected to Lightspeed** bar (with **View in POS** and **Sync**) only appears when the store's POS provider is Lightspeed and the menu is linked to a Lightspeed menu. Select the menu in **Lightspeed Menu** on the Lightspeed settings page and click **Save**. ### The sync fails part-way The progress bar shows the stage that failed. Common causes: * The menu no longer exists in Lightspeed, or is no longer available on the connected business location — re-pick it in **Lightspeed Menu**. * The authorisation has expired or been revoked — reconnect (above). * The account profile in **Specify account profile when syncing menu** no longer exists in Lightspeed — set it back to **No profile** or pick a current one. ### Some items didn't import * Items whose Lightspeed pricing strategy makes the price positive, negative or a percentage of the total are deliberately skipped — they have no fixed price to import. * Items inside sub-screens land in the parent category unless **Import Sub-screens as categories** is on. * Products in the `integration` menu entry group (the storekit delivery, discount and service-charge products) are skipped on purpose. ### Names or descriptions are in the wrong language Set **Language** to the Lightspeed locale you want. storekit falls back to `en` for items with no text in that locale. ### My storekit images or descriptions were overwritten Turn on **Don't update menu images** and **Don't update menu description**. Everything else in the menu is rewritten from Lightspeed on every sync. ## Orders ### Orders fail with "Not processed before validity ended" The Lightspeed Active Device — your master iPad — wasn't online to collect the order. See [Orders Failing: Till Offline](/docs/guides/integrations/pos/lightspeed/till-offline) for the full checklist and how to resend the order. ### Orders aren't reaching Lightspeed at all * Check **Integration Status** is on — the label should read *Enabled - sending orders to Lightspeed*. * Check the store is linked to the right business location. * Open the order in storekit and read the failure reason recorded against it. ### Orders are rejected as soon as they're sent * The account profile code must exist in Lightspeed. If a row under **Account Profile Codes** is empty, storekit sends `storekit` — either create that profile in Lightspeed or select a real one for **Pickup**, **Delivery**, **In Store** and **Add to Bill**. * The delivery, discount and service-charge products must exist in Lightspeed with the SKUs set in **Delivery Product Code (SKU)**, **Discount Product Code (SKU)** and **Service Charge Product Code (SKU)** (defaults: `STOREKIT_DELIVERY`, `STOREKIT_DISCOUNT`, `STOREKIT_SERVICE_CHARGE`). A missing SKU fails the whole order. * Item SKUs must still match. Re-sync the menu after changing SKUs in Lightspeed. ### An order failed because an item is restricted Lightspeed refused the order under a sales restriction. storekit snoozes the affected items until 8am the next day and emails the store; check the item's stock or restriction in Lightspeed, then unsnooze it in storekit. ### Orders fail and then stop retrying storekit sends a failed order up to 5 attempts in total (the original send plus four retries) before marking it **Failed**. Orders being added to an existing bill, and failures reported as the item not being addable, are not retried at all. Once the cause is fixed, resend the order with **More actions** → **Resend order to POS**. ### Pre-orders arrive too early or too late **Buffer Orders** controls this. With **Buffer (in minutes)** set, the order is injected that many minutes before the requested time; with it empty, storekit uses the store's prep-time calculation. ### The wrong table is used for in-store orders storekit sends the table's POS ID as the Lightspeed table number. If only a few tables are wrong, correct their **POS ID** under **Stores** → your store → **Settings** → **Tables** — see [Editing Tables](/docs/guides/fulfillment/dine-in-tables#editing-tables). Re-run **Sync floorplan** only when the whole floor plan needs reconciling: it covers every area in the store and overwrites hand-adjusted tables, as described in [Floor Plan & Tables](/docs/guides/integrations/pos/lightspeed/dine-in#re-syncing). ## Stock & Availability ### Sold-out items are still orderable * **Stock Webhook** must be on — the label should read *Enabled - stocks updated automatically*. * storekit matches stock updates on SKU and on the connected business location, so an item whose SKU differs between systems won't update. Re-sync the menu. ### The store keeps closing itself That's **Sync order readiness**: Lightspeed is reporting the location as not ready for online orders, so storekit closes the store and reopens it when Lightspeed reports it ready again. Turn the setting off if you don't want the POS driving store availability, and turn off **Order readiness emails** to stop the notifications. ### Customers aren't told their order is ready **Ready for pickup notifications** must be on for Lightspeed to drive the ready-for-pickup status. ## Pay at Table ### The guest sees no bill * The table must exist in both systems with the same number — run **Sync floorplan**. * There must be an open check on that table in Lightspeed. ### Payments fail * Check **Payment Method PAT** points at a Lightspeed payment method that's still active. With nothing selected storekit reports payments as `APM`, which must exist in Lightspeed. * Gift card and loyalty payments use **Gift Card Payment Method** — the same applies to it. * The failure reason from Lightspeed is stored against the payment, and the bill is flagged so staff can settle it on the POS. ### A round of drinks didn't make it onto the bill Orders added to an open bill aren't retried. Check the order's failure reason in storekit and add the items on the POS if needed.
