- Start your Lightspeed integration today and see live GP data within 24 hours.
7-Step Integration Checklist for Lightspeed Restaurant
- Confirm you hold Lightspeed Restaurant admin credentials, not a manager-level login.
- Ensure supplier invoices already arrive in Jelly via email or photo upload.
- Log in to your Jelly account and navigate to Settings → Integrations.
- Navigate to Settings → Integrations in your Jelly account and select Lightspeed Restaurant.
- Click Connect and sign in to your Lightspeed Restaurant account when prompted.
- Grant the requested data permissions so Jelly can read item-level sales in real time.
- Select the POS categories you want to sync, typically Food and Beverages, then confirm.
The connection completes in approximately five minutes. Your Flash Report, Price Alerts, and Sales Mix data begin populating after the first completed sale.

Before You Begin the Lightspeed Connection
Three things must be in place before you start the Lightspeed Restaurant integration setup.
- Lightspeed admin access. A standard manager login does not carry the API permissions Jelly requires. If you are unsure of your access level, check under Account → Staff in your Lightspeed back office. Jelly flags this requirement at the point of connection so there is no ambiguity.
- An active Jelly account. Your account must be live and your location configured before the integration can be linked.
- Supplier invoices already arriving in Jelly. The POS integration calculates gross profit by comparing sales revenue against ingredient costs. Those costs come from scanned invoices. Without invoice data, the margin reports have nothing to calculate against. Once these prerequisites are in place, the integration delivers immediate business value.
Why Real-Time GP Reporting Matters
Manual GP reporting in a busy kitchen typically means waiting until the end of the week or the end of the month to understand whether the business made money. By the time that data arrives, a supplier price increase has already eroded three weeks of margin.
Connecting Lightspeed Restaurant to Jelly removes that lag entirely. The admin time saved, previously spent pulling sales figures, cross-referencing invoices, and building spreadsheet reports, is recovered immediately. Jelly customers see an average gross-margin improvement of 2 percentage points within the first three months, with some operators achieving significantly more. One operator moved GP from 65% to 72% within 12 weeks on approximately £500,000 in revenue.
Step-by-Step Integration Walkthrough
Confirm Your Lightspeed Series
Lightspeed Restaurant operates across three hardware and software generations: K Series, L Series, and O Series. The Jelly integration works with all three through the same API-based connection flow. If you are unsure which series your venue runs, check the footer of your Lightspeed back-office login screen or contact your Lightspeed account manager. The series does not change the steps inside Jelly.
Find Jelly from Lightspeed or Jelly
Jelly has an official integration with Lightspeed, so you can start the connection from either system. From Lightspeed, open the marketplace in your back office, search for Jelly, and follow the link to the authorisation screen. From Jelly, go to Settings → Integrations → Lightspeed Restaurant and click Connect.
Grant Permissions and Select Categories
Jelly requests read access to item-level sales data. The integration does not require write permissions to your Lightspeed account. After you grant permissions, select the categories to sync.
Most operators choose Food and Beverages. Operators running a retail component can include additional categories at this stage.
Menu-Item Mapping Best Practice
After the connection is live, Jelly surfaces only the POS items that have recorded a sale since the integration was connected. This behaviour keeps the mapping screen clean and free of legacy menu items that no longer appear on your current menu.
Because only active items appear, you can focus your mapping effort on dishes that actually contribute to current revenue. Work through these items and link each one to its corresponding dish in Jelly's Cookbook, because accurate mapping is what drives accurate GP figures. A POS item linked to the wrong dish will produce misleading margin data.
Prioritise your highest-volume and highest-cost items first. Then work through the remainder during a quieter service period.
What Happens After Setup Completes
Once the integration is live and the first transaction has been recorded, three reports become available within 24 hours.
- Flash Report: A daily, weekly, or monthly view of gross profit margin calculated from your Jelly invoice costs and your Lightspeed sales data.
- Price Alerts: Automatic flags whenever a supplier increases or decreases the price of an ingredient, giving you the evidence needed to negotiate credits or switch suppliers.
- Sales Mix: A view of which dishes are selling most and which are most profitable, enabling data-driven menu engineering decisions.
Troubleshooting Common Integration Issues
The following table shows the four most common integration issues, their likely causes, and how to resolve them.
| Issue | Likely Cause | Resolution | Time to Fix |
|---|---|---|---|
| Connection fails at authorisation | Login used is not an admin account | Log in with Lightspeed admin credentials, then check under Account → Staff | Under 5 minutes |
| POS items not appearing in mapping screen | No sales recorded since integration connected | Complete a test transaction in Lightspeed, then refresh the Jelly mapping screen | Under 10 minutes |
| GP figures appear as zero or blank | Dishes not yet mapped, or no invoices in Jelly | Complete menu-item mapping and confirm at least one supplier invoice has been scanned | Under 30 minutes |
| First sync delayed beyond 24 hours | API queue during high-traffic periods | Contact Jelly support via the in-app chat, as syncs typically resolve within one business day | 1 business day |
How to Measure Integration Success
Three indicators confirm the integration is working correctly. First, your Flash Report shows a live GP percentage that updates daily without any manual input. Second, Price Alerts begin firing within the first week as supplier invoices continue to arrive. Third, the time your team spends pulling sales and cost data drops to near zero, and that admin time previously spent on spreadsheet reconciliation is recovered immediately.
Advanced Tips and Next Steps for Operators
Once the Lightspeed integration is stable, three additional workflows extend the value further. Connecting Jelly to Xero enables a one-click push of every digitised invoice into your accounting software, which reduces bookkeeping time by approximately 90%.
For operators running delivery menus, Jelly's Cookbook allows you to duplicate existing dishes and layer in delivery commission costs to produce a separate, accurately costed delivery menu. For multi-site operators, the same integration process applies at each location. Each site connects independently, and all GP data is visible from a single Jelly account.

Frequently Asked Questions
How Jelly works across Lightspeed K Series, L Series, and O Series
The connection process inside Jelly works across Lightspeed Restaurant K Series, L Series, and O Series. All three series use the same API-based authorisation flow. Open Jelly, navigate to Integrations, select Lightspeed Restaurant, sign in with your Lightspeed admin credentials, grant permissions, and select your categories. If you are unsure which series you are on, the Lightspeed back-office footer or your Lightspeed account manager can confirm it, but this does not change anything you do inside Jelly.
Required Lightspeed access level for integration
You need full admin access to your Lightspeed Restaurant account. A standard manager-level login does not carry the API permissions required for Jelly to read item-level sales data. Jelly flags this requirement at the point of connection.
If your login does not have admin rights, ask the account owner to either elevate your permissions or complete the integration step themselves. Once connected, day-to-day use of Jelly does not require ongoing admin access to Lightspeed.
What happens to Jelly data if you change POS
Your invoice data, dish costings, and historical GP reports are held within Jelly. If you move to a different POS system that Jelly supports, you disconnect the existing integration and connect the new one using the same quick flow. Your Cookbook recipes and supplier invoice history are unaffected.
If you move to a POS system not yet supported by Jelly, your cost-side data and reports remain accessible. Only the live sales feed pauses until a compatible integration is available.
How quickly gross profit data appears after connecting
The Flash Report, Price Alerts, and Sales Mix begin populating after the first completed sale recorded in Lightspeed after the integration goes live. The speed of the initial data depends on how quickly sales are transacted and how many dishes have been mapped in Jelly. Operators who complete menu-item mapping on the same day as setup typically see their first live GP figures the following morning.
Where Jelly appears in the Lightspeed marketplace
Jelly has an official integration with Lightspeed, which makes it straightforward to find and authorise directly from your Lightspeed back office. You can also initiate the connection from inside Jelly by navigating to Settings, then Integrations, and selecting Lightspeed Restaurant. Both routes lead to the same authorisation screen and complete through the same quick setup process.
Conclusion: Turn Lightspeed Data into Daily GP Control
The Lightspeed Restaurant integration setup takes only a few minutes and immediately replaces hours of weekly manual work with live gross-profit data. From the moment the first sale completes in Lightspeed, Jelly's Flash Report, Price Alerts, and Sales Mix are working in the background. Your existing POS data turns into daily margin control without spreadsheets, manual entry, or delayed reports.
For UK restaurant, pub, and boutique hotel operators already running Lightspeed Restaurant, this integration provides a fast route to real-time kitchen profitability.
