Key Takeaways for UK Restaurant Margins
- Prime cost (food + labour) under 65 % of revenue remains the most controllable profitability lever for UK restaurants in 2026.
- Automated invoice capture and daily price alerts remove manual data entry and highlight cost changes within 24 hours.
- Live dish costing through POS integration gives real-time gross-profit visibility so you can adjust menus and portions immediately.
- Weekly KPI reviews and demand-led rota changes keep labour costs within the 30–35 % benchmark without hurting service.
- Book a demo with Jelly to set up these six cost-control workflows and protect your margins this week.
Workflow 1: Capture Invoices Automatically and Review Price Alerts Daily
Objective: Remove manual data entry and spot ingredient price changes within 24 hours of delivery.
Required inputs: Supplier invoices (paper or email), Jelly account at £129/month per location.
Actions: (1) Forward supplier email invoices to your Jelly inbox or photograph paper invoices in the Jelly mobile app. (2) Once received, Jelly digitises every line item, including quantity, SKU, price and tax, and stores it against each product. (3) Open the Price Alert report each morning and flag every increase above 3 %, because these lines hit your margin fastest. (4) Log the flagged items for supplier negotiation in Workflow 5 so you can turn them into credits or better rates.
Success signals: No manual data entry, and price alerts visible within 24 hours of invoice receipt.
Time estimate: 15 minutes per week compared with 10–20 hours using a manual spreadsheet process.
| Task | Manual Process | With Jelly | Time Saved |
|---|---|---|---|
| Invoice data entry | 10–20 hrs/week | Automated | 10–20 hrs/week |
| Price-change detection | End-of-month review | Daily alert | Weeks of lag removed |
| Dish cost update | 28 min per dish | 3 min per dish | ~25 min per dish |
| GP visibility | Monthly accountant report | Real-time Flash Report | Up to 30 days lag removed |
Workflow 2: Use Live Dish Costing and Sales Mix from Your POS
Objective: See the gross profit of every dish in real time and spot items that drag down your sales mix.
Required inputs: Jelly connected to your POS. Square, EPOS Now, Lightspeed and Toast are all supported via real-time API. Setup takes about five minutes: open Jelly, go to Integrations, sign in to your POS, grant permissions, then select categories to sync.
Actions: (1) Build each dish in Jelly’s Cookbook by clicking on ingredients already populated from scanned invoices. Jelly handles unit conversions and wastage percentages automatically. (2) Review the Sales Mix report weekly and identify dishes with GP below target, highlighted in red. (3) For low-GP, high-volume dishes, adjust portion size, swap an ingredient or change menu placement. (4) For high-GP, low-volume dishes, test new placement and stronger descriptions to lift sales.
Success signals: Every dish shows a live GP %, and red flags trigger action within the same week. Sushi Revolution achieved gross profits 2–3 % higher on average after using live dish costing and separate delivery menu targets through Jelly.
Time estimate: 20–30 minutes per week.
Workflow 3: Log Waste and Track Food Cost Variance
Objective: Turn waste into a visible, controllable cost instead of an invisible margin leak.
Required inputs: Jelly Cookbook with recipes built, plus a short daily kitchen log on paper or digital.
Actions: (1) Record spoilage and prep waste against each ingredient in Jelly’s wastage percentage field. (2) At week-end, compare theoretical food cost from Jelly’s recipe costs multiplied by units sold against actual invoice spend. (3) Treat any variance above 2 % as a trigger for root-cause review, such as over-ordering, poor prep yield or theft. (4) Adjust par levels and order quantities based on what you find.
Success signals: Theoretical versus actual variance stays below 2 %, and waste cost appears as a clear line item in weekly reporting.
Time estimate: 10 minutes for daily logging and 20 minutes for the weekly variance review.
Workflow 4: Adjust Rotas Based on Real Demand
Objective: Match labour spend to actual covers so labour cost stays within the 30–35 % benchmark.
Required inputs: Jelly Flash Report for daily and weekly GP, plus POS sales data by day-part.
Actions: (1) Pull the Flash Report for the prior week and identify the two lowest-revenue day-parts. (2) Cross-reference those periods with your rota and calculate labour cost as a percentage of revenue for each shift. (3) Reduce hours on consistently low-revenue shifts and redeploy those hours to high-demand periods. (4) Check labour % again in the following week’s Flash Report to confirm improvement.
Success signals: Labour cost % moves toward the 30–35 % target within four weeks, with no service-quality complaints linked to rota changes.
Time estimate: 30 minutes per week.

Workflow 5: Use Price Alerts to Strengthen Supplier Negotiations
Objective: Turn Jelly’s Price Alert log into credit notes and stronger contract terms.
Required inputs: Jelly Price Alert report and the list of flagged increases from Workflow 1.
Actions: (1) Export the Price Alert log for the past four weeks. (2) Group increases by supplier and calculate the cumulative cost impact for each one. (3) Contact each supplier with the specific SKU, previous price, new price and date of change, then request a credit note or a return to the prior rate. (4) Where a supplier refuses, use the data to benchmark against alternatives and support switching decisions. (5) Log outcomes in Jelly’s Insights Dashboard so you can track wins over time.
Success signals: At least one credit note or rate reduction per supplier per quarter.
Time estimate: 45 minutes per week during active negotiation cycles.
Cairn Lodge Case Study: Stuart Noble, Head Chef at Cairn Lodge Hotel, used Jelly’s price-alert data to challenge supplier increases directly. “Price hikes were crushing our margins, I felt helpless. With Jelly, every dish cost is up-to-date at my fingertips. We slashed food costs by 5 % in a month.”
Workflow 6: Review Weekly KPIs in a Single Dashboard Session
Objective: Close each week with a 30-minute review that confirms GP is on target and flags drift before it compounds.
Required inputs: Jelly Insights Dashboard, Flash Report, Price Alert log and the waste variance figure from Workflow 3.
Actions: (1) Open the Flash Report and record weekly GP %, food cost % and labour cost %. (2) Compare against the prior week and your prime cost target. (3) Review the top five Price Alert items and confirm any negotiation actions from Workflow 5 are logged. (4) Check waste variance and schedule a kitchen briefing if it sits above 2 %. (5) Note one clear action item for the following week and assign an owner.
Success signals: GP % remains stable or improves week-on-week, and prime cost trends toward your target.
Time estimate: 30 minutes per week.
Amber Case Study: Amber restaurant in East London saves £3,000–£4,000 per month through automated invoice processing, real-time costing and price-change alerts, achieving about 68× ROI. Chef-Owner Murat Kilic: “Jelly keeps my business alive.”
The Howard Arms Case Study: Owner Ruth Seggie: “Our accountant said we’d be lucky to hit 60 % gross profit. After using Jelly, we reached 80 %. Now I sleep better knowing my costs are under control and can react instantly, not weeks later.”
Explore the weekly KPI workflow and see how it scales for operators at your revenue level.
The six workflows above give you the operational mechanics to control food and labour costs. To decide which changes to prioritise, you also need to understand how each move affects contribution margin.
How to Increase Contribution Margins Without Raising Prices
Contribution margin is the revenue remaining after variable costs, mainly food and beverage, are subtracted. Several tactics increase this margin without touching menu prices. (1) Menu engineering uses Jelly’s Sales Mix report to highlight high-GP, high-popularity dishes, your “stars”, and give them prime menu space, while you retire or reformulate low-GP, low-popularity “dogs”. (2) Portion standardisation sets precise gram weights in Jelly’s Cookbook so every plate costs the same, regardless of which chef is on shift. (3) Delivery menu separation recognises that delivery platforms charge average commissions of 30 %, and Jelly’s Delivery Menu Creation tool lets you build a separate menu with commission built into the target GP, which protects dine-in margins. (4) Ingredient substitution uses Price Alerts and live costing to show the GP impact of switching to an alternative ingredient before you commit.
Common Mistakes That Destroy Restaurant Margins
1. Delayed financial data. Relying on monthly accountant reports allows price increases to compound for weeks before you act. Real-time invoice scanning removes this lag.
2. Uncosted menu changes. Adding or modifying dishes without updating recipe costs in a live system creates invisible margin leaks. Every menu change should trigger a dish-cost update.
3. Ignoring the sales mix. A dish with a 70 % GP that sells 10 covers per week contributes less than a 60 % GP dish selling 80 covers. Volume and margin need to be evaluated together.
4. Flat labour scheduling. Using the same rota regardless of forecasted covers inflates labour cost % on quiet shifts. Demand-led scheduling in Workflow 4 corrects this.
5. Accepting supplier price increases passively. Without itemised price-change data, operators have no leverage. The Price Alert feature removes this blind spot.
6. Treating waste as unavoidable. Untracked waste typically adds 2–4 % to food cost. Logging it in Workflow 3 makes it visible and manageable.
Apply the 4Ps and 7Ps to Margin Protection
The 4Ps, Product, Price, Place and Promotion, plus the extended 7Ps that add People, Process and Physical Evidence, usually sit in a marketing playbook. Each one also affects margin directly.
Product: Reformulating dishes to use lower-cost, same-quality ingredients protects GP without changing the customer proposition. Jelly’s live costing turns reformulation into a data-led decision.
Price: This playbook focuses on avoiding price increases. When a rise becomes unavoidable, Jelly’s Sales Mix data highlights dishes with the least price sensitivity, where popularity is high and substitutes are limited, so you can apply modest increases safely.
Place: Delivery channels carry a structural margin disadvantage because of platform commissions. Treating delivery as a separate P&L with its own GP target, as Sushi Revolution does via Jelly, prevents delivery volume from hiding weak dine-in profitability.
Promotion: Promoting high-GP dishes through specials boards, staff upselling and digital channels improves the overall sales mix without changing the printed price list.
People and Process: Automating invoice capture and dish costing removes the dependency on chefs to complete admin accurately under pressure, which is the biggest source of data drift in manual systems.
The No-Price-Increase Playbook in One View
Six workflows sit on one platform and support zero menu price changes. Workflow 1 captures every invoice automatically and surfaces price alerts daily. Workflow 2 connects your POS to live dish GP data. Workflow 3 logs waste and closes the gap between theoretical and actual food cost. Workflow 4 aligns labour hours to real demand using Flash Report data. Workflow 5 converts price-alert evidence into supplier credit notes and better rates. Workflow 6 closes each week with a 30-minute KPI review that keeps prime cost trending toward the benchmark noted earlier. Jelly delivers all six workflows at a flat monthly rate per location.

Frequently Asked Questions
Who owns the data in Jelly?
You do. All invoice data, recipe costs, sales mix figures and GP reports belong entirely to the operator. Jelly does not sell, share or use your operational data for any purpose other than powering your own account. You can export your data at any time directly from the platform. This matters especially for multi-site operators and those preparing for investment or acquisition, where clean, auditable financial records carry significant value.
How long does onboarding take?
Most operators see value within the first week. The fastest route is to direct supplier invoices to your dedicated Jelly email address so price alerts and spending insights appear as soon as the first invoice arrives. Photographing invoices into the Jelly app delivers the same result within 24 hours. Connecting a POS system takes about five minutes. Building your full recipe Cookbook takes longer and depends on menu size, but the Price Alert and Flash Report features work independently of recipe completion, so you do not wait for a full setup before you see actionable data.
Can Jelly support multi-site rollout?
Yes. Jelly uses a flat monthly rate per location with no per-user or per-feature charges, which keeps costs predictable as you scale. Each location has its own invoice inbox, Cookbook and reporting dashboard, while owners and operations managers can access all sites from a single login. This central visibility helps operators managing two to five sites who need a consistent source of truth across locations without relying on each site’s chef to produce accurate manual reports. Populu, for example, lifted gross profit from 68 % to 72 % across 16 locations after connecting Jelly to their POS systems.
Start Protecting Your Margins This Week
Prime cost at the target level is achievable in 2026. Operators who hit that mark avoid constant menu price rises and instead replace manual spreadsheets with automated invoice-to-GP workflows that surface the right data at the right time. Jelly delivers those workflows at a flat monthly rate per location, integrates with Square, EPOS Now, Lightspeed and Toast in under five minutes, and supports measurable GP improvements within the first 12 weeks. The old way costs 10–20 admin hours and two margin points every month. The six workflows above cost about 30 minutes a week.
