How to Compare Branch Performance Fairly

Why Your Branch Reports Are Lying to You

A 10% sales increase at one site and a 10% drop at another should be easy to explain. But when the first branch is a 200-seat family restaurant and the second is a 50-seat late-night bar, the numbers don’t tell the same story. The family restaurant’s rise might be seasonal; the bar’s fall could be a one-off event. Without stripping out the noise, you’re comparing turnover to turnover, not performance to performance.

The problem isn’t the data—it’s the context. A £50,000 month at Branch A might look better than £30,000 at Branch B, but if Branch A is open 12 hours a day and Branch B is open 24, the comparison is meaningless. You need to adjust for the things you can’t control: hours, staffing, location, even the weather. Only then do the numbers start to tell you which branches are actually improving—and which ones need help.

Start by asking: What’s the fairest way to measure success when every branch has different rules? The answer isn’t just ‘sales’ or ‘profit’—it’s a set of adjusted metrics that account for the chaos outside your control.

The Three Metrics That Actually Matter

Turnover and profit are vanity numbers if you don’t know why they moved. Here’s what to track instead:

1. Sales per Hour (SPH)

A branch open longer isn’t necessarily more efficient—it might just be filling more hours with lower-margin business. SPH tells you how much revenue each hour of operation generates, adjusted for opening times.

Example: Branch A does £20,000 in 80 hours (£250/hr). Branch B does £15,000 in 60 hours (£250/hr). Same efficiency, different volume. But if Branch B’s SPH drops to £200/hr, you’ve got a problem—regardless of turnover.

2. Staff Cost per £1,000 Turnover

Labour costs vary by branch type, but the ratio of wages to sales reveals efficiency. A high-end café will always pay more per pound of turnover than a fast-food outlet, but the trend over time is what matters.

Example: If Branch A’s staff cost is £300 per £1,000 turnover and Branch B’s is £400, the gap might reflect different menus, not poor management. But if Branch B’s ratio climbs from £350 to £450 without a menu change, that’s a red flag.

3. Wastage per £1,000 Turnover

Food and drink wastage isn’t always visible in the accounts—it hides in over-portioning, spoilage, or staff theft. Track it per £1,000 of sales to spot branches bleeding cash silently.

Example: A £10 wastage cost on £50,000 turnover is 0.2%. At £100,000 turnover, the same £10 becomes 0.1%. The branch with higher turnover might look better, but if wastage is creeping up, the profit margin is shrinking.

The Hidden Cost of ‘Consistency’

Centralising menus, prices, and recipes across branches saves money—but only if the branches can actually use the same standards. A menu designed for a high-footfall city centre site might flop in a suburban branch where customers expect cheaper prices. The same goes for staffing: a 24-hour branch needs more overnight staff than a lunchtime-only one.

The trade-off is this: Tight control cuts costs, but local flexibility drives sales. If Branch A’s menu is 10% more expensive than Branch B’s, you’ll lose customers unless the higher prices justify the experience (e.g., premium ingredients, faster service).

Example: A chain with identical menus in London and Manchester might see London branches outperforming because locals expect higher prices. But if Manchester customers switch to cheaper competitors, the ‘consistency’ backfires.

The fix? Let branches adjust prices and menus within set guidelines—but track the impact. If Manchester’s adjusted menu brings in 15% more sales at a 5% lower margin, that’s a win. If it doesn’t, the ‘flexibility’ is just chaos.

How to Spot a Branch That’s ‘Fine’ but Failing

A branch might hit its sales target every month but still be losing money. Here’s how to tell:

Peak hours are shrinking. If lunchtime sales drop but evening trade holds, it’s not a volume problem—it’s a timing problem. Maybe the lunch menu isn’t competitive, or staffing is inefficient.
Average order value (AOV) is falling. Customers might be ordering more frequently, but spending less per visit. That’s a menu or pricing issue.
Delivery orders are up, but margins are down. Marketplace commissions eat into profit, and riders might be taking longer to arrive. If delivery is cannibalising dine-in sales, the branch is trading volume for thinner margins.

Example: Branch C’s turnover is flat, but its AOV drops from £12 to £10. If average food cost is 30%, that’s £0.60 less profit per order. Over 5,000 orders a month, that’s £3,000 in lost profit—without turnover changing.

The Report That Cuts the Noise

Most restaurant software gives you sales and profit numbers—but not the adjusted ones you need. You’re left guessing whether a branch’s performance is good or bad.

What you need is a branch comparison report that:

Adjusts turnover for opening hours (SPH).
Compares staff costs as a percentage of adjusted turnover.
Flags wastage spikes per £1,000 of sales.
Shows delivery vs. dine-in mix and margin impact.
Highlights menu performance by branch (e.g., ‘Branch D’s pasta sells 30% less than the average’).

Example: Berryin’s Reports & Analytics lets you roll up data across branches, then drill into the details. Set a baseline for SPH, staff cost ratios, and wastage, then watch for deviations. If Branch E’s SPH drops 10% but turnover stays the same, you know it’s not a sales problem—it’s an operational one.

What Breaks When You Compare Branches

Different payment methods. If one branch takes more card payments (higher fees) than another, the profit comparison is skewed. Adjust for payment mix.
Staff theft or waste. A branch with high wastage might look profitable on paper but is actually losing money. Track portion sizes and spoilage.
Local market shifts. A branch near a university might see big swings in student trade. Seasonal adjustments are essential.
Menu changes without tracking. If Branch F adds a new dish that flops, the sales drop might look like poor performance—when it’s just bad timing.
Delivery vs. dine-in margins. A branch pushing delivery hard might boost turnover but slash profit. Compare contribution margin (revenue minus variable costs) per order type.

Frequently asked questions

### Can I compare branches in different countries with the same report?

Not directly—currency, tax rates, and local market conditions make it messy. Instead, convert all figures to a single currency (e.g., USD or GBP) and compare ratios (e.g., staff cost per £1,000 turnover) rather than raw numbers. Focus on trends within each country first, then look for patterns across borders.

### What if one branch has a loyalty scheme and another doesn’t?

Loyalty schemes distort comparisons because they create repeat customers who might not otherwise visit. Adjust turnover by tracking new vs. repeat customers—if Branch G’s sales are up but 80% come from loyalty members, the growth might not be sustainable without the scheme.

### How do I handle branches with different rent costs?

Rent is a fixed cost, so it doesn’t affect operational efficiency metrics like SPH or staff cost per £1,000 turnover. Compare profit after rent to see which branches are truly viable, but use adjusted turnover metrics to spot inefficiencies before they hit the bottom line.

### What’s the best way to benchmark against competitors?

You can’t—competitors won’t share their numbers. Instead, benchmark against your own branches. Identify your top-performing branch by adjusted metrics (SPH, staff cost ratio, wastage), then ask: What’s it doing that the others aren’t? Replicate the mechanisms (e.g., faster service, better menu pricing), not just the outcomes.

### How often should I run these comparisons?

Monthly is the minimum, but weekly checks on key metrics (SPH, staff cost ratio) catch problems early. Use real-time dashboards to spot trends as they happen—like a sudden drop in AOV or a spike in wastage—before they become crises.

If your branches aren’t performing as you expect, the issue isn’t the numbers—it’s the context you’re missing. Start with adjusted metrics, then dig into the why. The branches that survive (and thrive) aren’t the ones with the highest turnover—they’re the ones with the most efficient operations.
