What You Gain From Connecting Your POS to Jelly
- POS sales integration automatically pushes every till transaction into accounting, inventory, and delivery tools without manual entry or end-of-day reconciliation.
- UK cafés using manual reconciliation lose 2–3 hours per week. Integrated systems cut that to under two hours per month and lift gross profit by 3–7 percentage points within 12 weeks.
- Jelly connects natively to Square, EPOS Now, Lightspeed, and Toast, delivering real-time item-level sales data, commission-adjusted delivery GP, and daily Xero posting that is fully MTD-compliant.
- Five-minute setup per POS plus automatic handling of VAT, discounts, and refunds removes the information lag that previously delayed pricing and supplier decisions.
- Connect your café’s POS to Jelly today and start seeing live gross-profit visibility within the first week.
The Hidden Cost of Manual Reconciliation for Cafés
Manual reconciliation quietly drains time and margin from UK cafés turning over £500k or more. When accounting software does not integrate cleanly with a hospitality POS, staff spend 2–3 hours per week manually moving data. Integrated EPOS systems cut that admin to under two hours per month through automatic reconciliation, real-time sales reporting, and direct connectors to accounting platforms such as Xero.
The impact on margins is just as clear. Jelly customers who connected their POS saw gross profit climb from 65% to 72% within 12 weeks on approximately £500,000 in revenue. Populu lifted GP from 68% to 72% across 16 locations. Amber restaurant saves £3,000–£4,000 per month, roughly 68× ROI, after automating invoice and sales data flows through Jelly.
Delayed data keeps pricing decisions weeks behind reality. By the time a monthly accountant report arrives, a dish that eroded margin in week one has been sold hundreds of times. Connecting your POS to Jelly closes that gap on day one and turns every new sale into live margin insight.

How Jelly Turns Till Transactions Into Real-Time Margins
Jelly sits between your POS and your financial stack and converts every sale into live GP. The moment a transaction completes at the till, item-level sales data flows into Jelly’s Kitchen section, where each dish is already costed from scanned supplier invoices. Jelly calculates gross profit in real time and pushes a clean, VAT-compliant summary to Xero. You avoid spreadsheets, copy-and-paste, and compliance gaps.
The platform is built around four pillars: Accounting, Delivery, Inventory, and Loyalty. For sales-data inflow, the critical pillars are Accounting, which automates your Xero push, and Delivery, which calculates commission-adjusted GP for Deliveroo and Uber Eats orders. Once your POS is connected, the Flash Report displays your gross profit percentage for today, this week, or this month, updated in real time as transactions complete. The Sales Mix report ranks every dish by both popularity and profitability, so you can see at a glance which items drive margin and which erode it. Price Alerts flag every supplier price movement the moment a new invoice is scanned.
Jelly integrates natively with four POS systems via real-time API: Square, EPOS Now, Lightspeed, and Toast. Each integration delivers item-level sales data the moment a transaction completes and works alongside your existing tools, so you keep your current POS and gain live GP reporting.
Square Integration: Five-Minute Connection Walkthrough
Square’s reliable API keeps the connection straightforward and fully user-led from within Jelly.
- Open Jelly and navigate to Integrations.
- Select Square and click Connect.
- Sign in to your Square account and grant the requested permissions.
- Select which Square categories to sync, for example Food and Beverages.
- Map each POS item to the corresponding Jelly dish so cost and margin calculations stay accurate.
Correct VAT handling sits at the heart of this setup. Café POS systems must automatically apply correct VAT rates per item and order type, such as 20% standard rate for hot food and alcoholic drinks and 0% for most cold takeaway food, to prevent misclassification errors. Jelly’s Xero push preserves these line-item VAT rates and keeps your digital records MTD-compliant without manual intervention.
Jelly is not currently listed on Square’s marketplace. The integration still runs fully through Jelly’s own Integrations page.
EPOS Now Integration: Line-Level Accuracy on Discounts and Refunds
EPOS Now is widely used by independent and single-site operators across the UK, so it often becomes the first POS that cafés connect to Jelly for automated margin reporting.
The connection process for EPOS Now follows the same five steps described in the Square section above. You navigate to Integrations in Jelly, select EPOS Now, sign in and grant permissions, choose product categories to sync, and map items to dishes.
Jelly then processes all discount and refund calculations at the individual line level for EPOS Now transactions, which keeps margin data accurate even when orders are complex. Under UK VAT rules, discounts are calculated on the price actually paid and no VAT is due on returned goods. Jelly handles both automatically and keeps your GP view correct.
Lightspeed Integration: Real-Time Sales Mix for Dine-In and Delivery
Lightspeed is a valued POS partner and appears on the Lightspeed marketplace, which makes discovery and connection simple for existing Lightspeed Restaurant users.
The connection process for Lightspeed mirrors the five steps outlined in the Square section. You open Jelly, go to Integrations, select Lightspeed, sign in, grant permissions, choose categories to sync, and map items to dishes.
Real-time sales mix data from Lightspeed then feeds directly into Jelly’s Sales Mix report. Operators gain an instant view of which dine-in and delivery menu items drive GP and which erode it after commission, so menu changes become data-led instead of guesswork.
Toast Integration: Scaling Cleanly Across Multiple Sites
Toast is a widely adopted POS system and is gaining traction in the UK, particularly among larger operators with several locations.
The connection process for Toast again follows the same five steps described for Square. You use Jelly’s Integrations page, select Toast, sign in, grant permissions, choose categories, and map items to dishes.
For multi-site operators, the same five-step process repeats per location. Jelly’s POS-to-dish linking only surfaces items sold since the integration was connected, so the mapping stays clean and free of legacy menu clutter. That behaviour becomes a real advantage when you roll out across several sites at once.
Walk through the setup live for your specific POS. Whether you are connecting one site or rolling out across multiple locations, the process stays the same.
Connecting Deliveroo and Uber Eats for Commission-Adjusted GP
Delivery platforms such as Deliveroo and Uber Eats charge average commissions of 30%, squeezing restaurant margins. Without a commission-adjusted GP view, operators routinely underprice delivery menus and only discover the loss at month-end.
Jelly solves this by pulling delivery sales data into the same margin engine used for dine-in. Sushi Revolution uses Jelly to set separate target gross profits on dine-in and delivery menus, accounting for 30% delivery commissions, which results in actual gross profits 2–3% higher on average. The Delivery Menu Creation feature in Jelly’s Kitchen section lets operators duplicate existing menu items, factor in commission overheads, and build a separate, profitable delivery menu without rebuilding recipes from scratch.
Every delivery sale then flows into the Flash Report alongside dine-in revenue. You see a single, commission-adjusted GP figure across all channels instead of juggling separate spreadsheets.
Automatic Xero Posting and Making Tax Digital Compliance
Jelly’s one-click Xero push satisfies this requirement. Each day’s sales, including VAT breakdowns, refunds, and payment method splits, post automatically to the correct Xero accounts. When a café POS integrates with Xero, every sale at the till flows directly into accounting records without manual entry, which eliminates hours of reconciliation work and reduces the risk of data entry errors. Jelly customers report a 90% reduction in bookkeeping time after activating the Xero integration.
From April 2026, sole-trader café owners with income over £50,000 must keep quarterly digital records and submit updates to HMRC under MTD for Income Tax Self Assessment. A clean, automated POS-to-accounting data flow therefore becomes a compliance necessity as well as an efficiency gain.
Common UK POS Integration Pitfalls to Avoid
Most cafés face the same few issues when they connect a POS to Jelly for the first time.
- Admin access: Connecting any POS to Jelly requires admin-level access to the POS account. Jelly flags this requirement upfront, but it remains the most common friction point during setup. Confirm access before starting.
- VAT rounding: Poor field mapping of currency formats, date formats, tax calculations, and decimal rounding rules distorts data and leads to inaccurate financial reporting. Jelly handles rounding at line-item level to match HMRC expectations.
- Discount and refund handling: Configure your POS to pass discount and refund data at line level, not as a lump adjustment. Jelly processes these correctly for EPOS Now and all supported systems, but the source data must be structured correctly.
- Missing delivery channel data: A missing third-party delivery feed can leave around 30% of multi-channel revenue invisible to an inventory system. Connect Deliveroo and Uber Eats through Jelly alongside your POS to avoid this blind spot.
- Legacy menu clutter: Jelly’s POS-to-dish linking only surfaces items sold since the integration was connected. You do not need to manually archive old menu items before setup.
Measure Your Results With This 30-Day Checklist
The first month after connection should prove that the integration saves time and improves GP. Use this checklist to track progress.
- Week 1: Confirm item-level sales are appearing in Jelly’s Kitchen section and the Flash Report is populating with live GP data. Admin time for end-of-day reconciliation should already be falling.
- Week 2: Now that live GP data is flowing, review the Sales Mix report to identify your three lowest-margin dishes. Cross-reference each one with the Cookbook to confirm recipe costs are current, because outdated ingredient prices distort margin calculations and push you to fix the wrong dishes.
- Week 3: With your margin data validated in Week 2, verify that the Xero push is posting daily summaries with correct VAT breakdowns. If you find manual entries bridging gaps, the digital link HMRC requires under MTD is broken, so flag this immediately and correct the integration before month-end.
- Week 4: Compare weekly admin hours against the pre-integration baseline. You should see the 15–20 hour monthly burden drop to the sub-two-hour level mentioned earlier. That time saving frees you to use live GP data and Price Alert flags to open supplier negotiations on ingredients that erode margin.
Within 12 weeks, Jelly customers consistently report meaningful GP improvements. The combination of live margin visibility, automated Xero posting, and commission-adjusted delivery GP removes the information lag that previously made strategic decisions reactive instead of proactive.

Frequently Asked Questions
How long does it actually take to connect my POS to Jelly?
Connecting any of Jelly’s four supported POS systems, Square, EPOS Now, Lightspeed, and Toast, takes approximately five minutes. The process is the same across all four: open Jelly, click Integrations, sign in to your POS, grant permissions, and select which categories to sync. Mapping POS items to Jelly dishes adds a little time, and Jelly only surfaces items sold since the integration was connected, so there is no legacy clutter to work through. The most common delay is not having admin access to the POS account ready, so confirm that before you start and the setup stays genuinely five minutes.
Does Jelly work if I use multiple POS systems across different sites?
Jelly supports multi-site and multi-POS setups cleanly. Each site connects its own POS to Jelly independently, following the same five-step process. Jelly then aggregates GP data across all locations into a single dashboard, giving operations managers and finance leads a consolidated view without logging into multiple systems. Populu used this approach to achieve the 16-location GP improvement mentioned earlier, which shows that the per-site connection scales cleanly without extra configuration.
What happens when I add a new menu item?
New menu items appear in Jelly automatically the first time they are sold through the connected POS. Jelly’s POS-to-dish linking only surfaces items that have recorded a transaction since the integration was active, so new items populate cleanly without manual imports. Once a new item appears, you map it to a Jelly dish in the Kitchen section, clicking on ingredients already populated from scanned invoices, and live costing begins immediately. The process takes around three minutes per dish, compared with the industry average of 28 minutes using spreadsheets.
Is Jelly’s Xero integration compliant with Making Tax Digital?
Jelly’s one-click Xero push maintains the digital link between your POS sales data and your accounting records that HMRC requires under MTD for VAT. VAT rates are applied at line-item level during transaction capture, 20% for hot food and alcoholic drinks and 0% for most cold takeaway food, and the daily summary posted to Xero includes the net value, VAT rate, and time of supply for each category, matching the digital record-keeping fields HMRC specifies. No manual re-keying occurs at any point in the chain, which satisfies the core MTD compliance requirement. From April 2026, MTD for Income Tax Self Assessment also applies to sole-trader café owners above the income threshold, and Jelly’s exportable, per-transaction data supports quarterly digital submissions.
How quickly will I see a gross profit improvement after connecting my POS?
Most Jelly customers see meaningful GP improvements within 12 weeks of connecting their POS. Live margin data surfaces underperforming dishes immediately, Price Alerts flag supplier price increases the same week they happen, and commission-adjusted delivery GP reveals which delivery menu items are actually profitable. One operator moved from 65% to 72% GP within 12 weeks on approximately £500,000 in revenue. Sushi Revolution achieved a 2–3% GP gain specifically from improving delivery menus through Jelly. The time saving, typically 2–5 hours of weekly admin, becomes visible from day one.
