Adding Vouchers to Your Existing Lightspeed Setup

The task is simple. You add voucher sales and redemptions to your current Lightspeed setup so every sale, partial redemption, and full redemption is captured automatically. Each transaction is reconciled accurately and appears in your live margin data inside Jelly. You remove spreadsheets from the process and keep Finance, Ops, and site teams working from the same numbers.

Prerequisites, Owners and Sequence

Confirm the technical pieces are in place before you start the integration work.

• Lightspeed Restaurant account with admin-level access (K-Series or L-Series).
• A confirmed voucher provider account with either VoucherCart or Voucher Connect.
• Jelly account with Lightspeed integration already live. Setup takes under five minutes via Jelly → Integrations → Lightspeed.
• Device camera or barcode scanner available at the till for QR redemption.

Once the technical setup is complete, brief front-of-house staff on the redemption workflow before go-live. This avoids confusion at the till and reduces guest wait times.

How Accurate Voucher Data Protects Your Margins

Manual voucher handling creates two linked problems. Revenue is recorded at the wrong time, and redemptions are rarely matched to the correct cost centre. The result is a distorted gross-profit figure that misleads purchasing decisions and supplier negotiations. Automatic voucher capture eliminates the timing and cost-centre errors that distort GP figures, giving Finance Leads daily margin visibility instead of waiting for month-end accountant reports.

That real-time visibility unlocks a second advantage. Jelly’s Price Alert feature can monitor the profitability of voucher-redeemed dishes as ingredient costs change. If a supplier raises prices on a dish frequently redeemed via voucher, the alert fires immediately. Operations Managers then have the data to reprice or renegotiate before margin damage builds up.

Before configuring your voucher integration, identify which Lightspeed platform version your site runs. The setup path differs significantly between K-Series and L-Series installations.

Which Lightspeed Version Your Site Uses

Lightspeed operates one restaurant POS platform (Lightspeed Restaurant POS, including the K-Series) in the UK market. Your voucher integration route depends on the version your site uses.

• K-Series: Lightspeed Restaurant is the current flagship cloud-based POS platform for restaurants in the UK. It supports the VoucherCart in-app redemption workflow via a configurable menu button on the terminal. This setup suits new deployments and multi-site operators.
• L-Series: An earlier platform that remains supported. Voucher and gift card integration uses Voucher Connect’s API bridge instead of an embedded app. Operators on L-Series should confirm with their Lightspeed account manager whether a migration is planned before investing heavily in L-Series-specific configuration.

How Jelly, VoucherCart and Voucher Connect Work Together

Jelly works alongside both VoucherCart and Voucher Connect to bring voucher and gift card data into your Lightspeed setup. VoucherCart provides a native app experience for K-Series users, with redemption controls available directly on the terminal. Voucher Connect provides an API bridge that works across both K-Series and L-Series and is the only option for legacy L-Series installations.

Both providers send voucher transaction data through Lightspeed’s API into Jelly. Jelly then matches voucher revenue against dish costs so you see real-time gross-profit performance without manual reconciliation.

Voucher Connect Setup for Lightspeed

Use this path if your site relies on Voucher Connect, particularly on L-Series or mixed estates.

1. Create your Voucher Connect account and select Lightspeed as your POS from the integrations menu.
2. Generate your API credentials inside Voucher Connect and copy the key and secret.
3. Paste credentials into Lightspeed under Settings → Integrations → Third-Party Apps.
4. Map voucher product types to the correct Lightspeed revenue categories such as gift card liability, food, and beverage for accurate reconciliation.
5. Test a redemption using a zero-value test voucher before going live with real transactions.
6. Confirm data in Jelly by checking that the redeemed item appears in your Flash Report within minutes of the test transaction.

If you use VoucherCart instead of Voucher Connect, typically on K-Series for the native app experience, follow the setup steps below.

VoucherCart Lightspeed Setup (K-Series)

1. Log in to VoucherCart and navigate to Integrations → Lightspeed Restaurant.
2. Authenticate with your Lightspeed admin credentials to grant VoucherCart API access.
3. Open Lightspeed Back Office, go to Apps, search for VoucherCart and install the app.
4. Assign the VoucherCart app to a floor plan or menu button on your terminal layout for quick till access.
5. Enable camera permissions on each terminal device that will process redemptions so QR scanning works reliably.
6. Configure revenue category mapping so voucher redemptions post to the correct account in Lightspeed and flow through to Jelly’s Flash Report.
7. Create at least one test voucher in VoucherCart, run a full redemption cycle, and confirm the transaction appears in Jelly within a few minutes.

VoucherCart Redemption Workflow on Lightspeed K-Series

Once VoucherCart is installed and configured, the redemption workflow at the till is straightforward. The operator opens the VoucherCart app via the configured menu button, then searches for the voucher by scanning its QR code with the device camera or entering the redeem code manually using the on-screen keyboard or a connected barcode scanner.

The product details page then displays redemption status, validity period, current value, redemption type (single-use or multi-use), and a full redemption history that logs who performed each action, when, where, and the value or quantity redeemed.

To complete redemption, the operator taps Redeem, enters the desired value or quantity, or uses Apply Max to apply the highest allowable amount up to the lower of remaining voucher value or check balance, then confirms. The redeemed amount is applied to the check as a payment and the check closes automatically if the balance reaches zero.

Lightspeed L-Series Voucher Integration with Voucher Connect

1. Contact your Lightspeed account manager to confirm API access is enabled on your L-Series account.
2. Set up a Voucher Connect account and select L-Series as your POS version.
3. Enter your Lightspeed API key and account ID into Voucher Connect’s integration settings.
4. Define voucher product categories in L-Series Back Office to match Voucher Connect’s product types.
5. Train till staff to enter voucher codes manually at the payment screen, because QR camera scanning is not natively supported on L-Series.
6. Verify that completed redemptions appear in Jelly’s sales data feed within the same trading session.

How Voucher Redemption Affects Stock and Costing

Voucher redemption on Lightspeed POS records the transaction as a payment against the open check, and the voucher balance updates in real time within the VoucherCart system. This transaction then passes through Lightspeed’s API to Jelly, where it is matched against dish-level costs. Jelly matches voucher transactions to dish costs for gross-profit visibility. Costing every menu item in Jelly’s Kitchen section is therefore essential for accurate inventory tracking alongside voucher revenue.

Lightspeed POS Voucher Reconciliation in Jelly

Once the integration is live, Jelly’s Flash Report consolidates voucher revenue with all other POS sales and matches it against ingredient costs updated from scanned invoices. Finance Leads can view daily, weekly, or monthly GP margins without manual data entry. Jelly’s Price Alert feature flags any ingredient price movement that affects the profitability of dishes commonly redeemed via voucher, so teams can act in the same week rather than discovering issues at month end.

Troubleshooting Common Lightspeed Voucher Issues

• VoucherCart app not visible on terminal: Check that the app is assigned to the correct floor plan in Lightspeed Back Office and that the terminal has been restarted since installation.
• QR scan not recognised: Confirm camera permissions are enabled on the device, or enter the redeem code manually.
• Redemption blocked on zero-balance check: A voucher cannot be applied to a check with no outstanding balance. Ensure the check has a positive balance before attempting redemption.
• Transactions not appearing in Jelly: Verify that the Lightspeed integration in Jelly is active under Integrations and that the correct POS categories, such as food and beverage, are selected for sync.
• Revenue category mismatch: If voucher redemptions appear in the wrong Jelly cost centre, revisit the revenue category mapping in Lightspeed Back Office and re-run a test transaction.

Measuring Success After Lightspeed Voucher Integration

Track a small set of metrics so you can see whether the integration is delivering value.

• Admin hours saved: Aim for a reduction of two to five hours per week that were previously spent on manual voucher reconciliation.
• GP accuracy: Flash Report GP margin should stabilise within the first trading week once voucher revenue is captured automatically.
• Redemption speed at till: The Apply Max function on VoucherCart reduces till time per redemption by removing manual value calculation.
• Price alert response rate: Track how quickly the team acts on Jelly Price Alerts for dishes linked to high-voucher-redemption menu items.

Advanced Tips for Lightspeed Voucher Integration in 2026

• Multi-site operators: Connect each Lightspeed site to Jelly individually under separate location profiles. Jelly’s flat-rate £129 per month per location pricing keeps scaling straightforward.
• Jelly Price Alert for voucher-heavy menus: Flag dishes that appear frequently in voucher redemptions and set tighter margin thresholds in Jelly so price increases trigger alerts before GP is affected.
• Delivery menu separation: Use Jelly’s Delivery Menu Creation feature to duplicate voucher-eligible dishes with delivery commission factored in. This protects margin on third-party platform orders.
• Redemption history audit: VoucherCart logs every redemption action with operator name, timestamp, location, and value. Export this monthly and cross-reference with Jelly’s Flash Report to catch any discrepancies early.

Frequently Asked Questions

Can I use VoucherCart with Lightspeed L-Series?

VoucherCart’s native in-app redemption workflow is designed for Lightspeed K-Series. L-Series operators should use Voucher Connect, which integrates via an API bridge compatible with the L-Series platform. If you are unsure which version your site runs, check Lightspeed Back Office to confirm your setup.

How does voucher revenue appear in Jelly?

Voucher redemptions processed through Lightspeed POS are passed to Jelly via the real-time API integration. They appear as item-level sales in Jelly’s Flash Report, where they are matched against dish costs from scanned invoices. Your GP margin figure then includes voucher revenue from the moment the check closes, with no manual entry required.

What happens if a voucher is only partially redeemed?

Partial redemptions are fully supported. The operator enters the specific value to redeem rather than using Apply Max, and the remaining balance is retained on the voucher for future use. The partial amount is recorded as a payment in Lightspeed and flows through to Jelly as a standard sale. The voucher’s updated balance is visible in the VoucherCart or Voucher Connect dashboard immediately after the transaction.

Does Jelly work with both VoucherCart and Voucher Connect simultaneously?

Yes. Jelly receives data from Lightspeed regardless of which voucher provider processed the redemption. Because Jelly integrates at the Lightspeed API level, any transaction completed through Lightspeed POS, whether initiated by VoucherCart, Voucher Connect, or a standard sale, is captured and mapped to your dish costs in Jelly. There is no need to configure separate connections for each voucher provider.

Conclusion and Next Steps

Lightspeed voucher integration with VoucherCart or Voucher Connect, paired with Jelly, removes the manual reconciliation burden that costs UK operators hours every week and hides true gross-profit margins. Version-specific setup, with K-Series using VoucherCart’s native app and L-Series using Voucher Connect’s API bridge, ensures every redemption is captured accurately and flows directly into Jelly’s real-time reporting. Finance Leads see live GP data daily, Operations Managers spend less time on admin, and kitchen teams can focus on service instead of spreadsheets.
