How to Raise Bar Attach Rate in a Computer Club
How to Raise Bar Attach Rate in a Computer Club
Section titled “How to Raise Bar Attach Rate in a Computer Club”To lift bar attach rate by 10–20 percentage points in the first month, use three levers in sequence: a standard offer at session checkout (+5–10 pp), a “rate + drink” combo (+3–7 pp), and menu visibility at the workstation (+3–5 pp). Attach rate is the share of sessions with a bar order; every percentage point of growth at average bar order B with N monthly sessions equals N × 0.01 × B in additional revenue — without changing rates.
Measure in IZI: Analytics → Bar. Attach rate definition is in the glossary; bar pricing methodology — in a separate guide.
Why This Matters to an Owner
Section titled “Why This Matters to an Owner”The bar is the club’s second revenue centre after gaming time. At a typical bar margin of 60–70%, every order contributes disproportionately high profit relative to service time.
The problem is that most clients don’t order at the bar by default — not because they don’t want to, but because they don’t think about it at the moment of decision. Attach rate measures those missed orders that could have happened with minimal effort.
Revenue uplift formula:
Δ bar revenue = Δ attach_rate × session_count × avg_bar_orderIllustration: attach rate from 15% to 30% with 500 sessions/month and avg bar order = B: Δ revenue = 0.15 × 500 × B = 75 × B additional orders per month.
At B = 100: +7,500 bar revenue per month. At 65% margin — +4,875 profit. Without changing rates, without new clients, without marketing.
Methodology: Three Attach Rate Levers
Section titled “Methodology: Three Attach Rate Levers”Lever 1: Standard Offer at Session Checkout
Section titled “Lever 1: Standard Offer at Session Checkout”The most powerful and cheapest lever. One phrase from the admin at every session start:
“Can I get you anything from the bar?”
F&B and retail research consistently shows this question converts 20–35% of clients who answer “yes.” Most of them wouldn’t have ordered on their own — not because they didn’t want to, but because they didn’t think about it.
Critical condition: the question is asked at every session checkout, by every admin. If part of a shift doesn’t ask — the effect is lost disproportionately. A standard only works as a standard.
What doesn’t work:
- “Would you like something from the bar — we have drinks and snacks?” — too long
- “Maybe something from the bar?” — “maybe” gives permission to say no
- “Do you need anything from the bar?” — “need” reduces conversion
What works:
- “Anything from the bar?” — neutral open question
- “Getting anything?” — informal, audience-appropriate
Lever 2: “Rate + Bar Item” Combo
Section titled “Lever 2: “Rate + Bar Item” Combo”A combo creates the expectation that a drink comes with gaming. The client sees “one hour + energy drink” as a package, not “one hour” plus “pondered the bar.”
Combo parameters:
Combo price = (hourly_rate + bar_item_price) × 0.90–0.95Discount = 5–10% vs individual pricesA discount is optional but improves combo conversion. Without a discount, a combo still works through “complete package” psychology.
Illustration:
Hourly rate = 200, energy drink = 80. Sum = 280. Combo: 200 + 80 × 0.90 = 272. Discount = 8 units.
Combo margin: (200 × 0.70) + (80 × 0.65) = 140 + 52 = 192 vs 140 without bar. Margin per session increase = +37%.
Which item to choose for the combo: the most marginal from the top 5 bestsellers. Usually energy drink or coffee.
Lever 3: Menu Visibility at the Workstation
Section titled “Lever 3: Menu Visibility at the Workstation”Clients can’t order what they don’t know about or can’t be bothered to walk to. Three visibility points:
Menu card at the monitor: a laminated A5 with the top 5 items and prices. Not a full menu — just what’s quick and popular. Goal: the client looks at the screen and sees “energy drink £2” in their peripheral vision.
QR code on the desk: links to the bar menu in the IZI mobile app. Order from your seat without standing up. Reducing friction is the key factor for mid-session additional orders.
Poster at the register: the client sees the menu while waiting for their session to start. Creates a decision moment before they’ve even sat down.
Parametric Revenue Uplift Formula
Section titled “Parametric Revenue Uplift Formula”Δ bar_revenue = Δ attach_rate × N_sessions × avg_bar_order
Δ bar_profit = Δ bar_revenue × bar_marginIllustration of three levers separately:
Baseline: 500 sessions/month, attach rate 15%, avg order B = 90, bar margin 65%. Current bar profit: 500 × 0.15 × 90 × 0.65 = 4,388
| Lever | Δ attach rate | New bar profit |
|---|---|---|
| Script only (+8 pp) | 23% | 500 × 0.23 × 90 × 0.65 = 6,728 (+53%) |
| Script + combo (+12 pp) | 27% | 500 × 0.27 × 90 × 0.65 = 7,898 (+80%) |
| All three levers (+17 pp) | 32% | 500 × 0.32 × 90 × 0.65 = 9,360 (+113%) |

Admin Scripts
Section titled “Admin Scripts”1. Core question at session checkout
Section titled “1. Core question at session checkout”“Anything from the bar?”
After asking — silence. Let the client think.
2. Combo offer at checkout
Section titled “2. Combo offer at checkout”“Or take it as a bundle: one hour + {drink} — {combo_price}. Saves you {discount} vs separate.”
Specific saving in currency, not percentage.
3. Client mid-session (2+ hours in)
Section titled “3. Client mid-session (2+ hours in)”“How’s it going? Can I bring you anything from the bar?”
Offer without approaching the seat — call across. Don’t disturb unnecessarily.
4. Client asks “what would you recommend?”
Section titled “4. Client asks “what would you recommend?””“{Specific item} — top seller here. {Second item} — if you want sugar-free. Which one?”
Two specific recommendations + a closed question. Not “check the menu” — that shifts the decision to the client.
5. Push reminder via IZI app (template)
Section titled “5. Push reminder via IZI app (template)”“{club_name}: how’s the session going? Order from the bar right from your seat — scan the QR code at your desk 🎮”
After 1 hour of session. Short, no pressure.
How to Measure Uplift
Section titled “How to Measure Uplift”Primary metric — attach rate:
Attach rate = sessions with bar order ÷ all sessions × 100%Analytics → Bar → period comparison view. Before launch vs after.
Supporting metrics:
- Average bar order value: should remain stable or grow (if falling — combo is priced too low)
- Bar revenue share of total club revenue: target range 15–25% for a club with a full bar
- Attach rate by time of day: see which lever works better morning vs evening
Signs the programme is working:
- Attach rate +5–10 pp in the first month
- Combo sales share > 15% of bar orders
- Average bar order stable or growing
When This Method Doesn’t Work
Section titled “When This Method Doesn’t Work”1. Bar is physically inaccessible or inconvenient
Section titled “1. Bar is physically inaccessible or inconvenient”If the bar is at the other end of the hall, no in-seat ordering option, no app — attach rate will be low regardless of scripts. Fix the physical barrier first.
2. Assortment doesn’t match the audience
Section titled “2. Assortment doesn’t match the audience”Budget-conscious younger clients won’t buy expensive coffee. An older audience won’t want cheap sweets. The assortment must align with audience price expectations and tastes. Check via the top 10 bestsellers.
3. High admin turnover
Section titled “3. High admin turnover”If there’s a new shift every 2 months — the script standard constantly “resets.” Include the script in new staff onboarding as a mandatory item.
4. Fundamentally low bar margin
Section titled “4. Fundamentally low bar margin”If margin on bar items is < 40% (e.g. selling alcohol or complex dishes with high cost of goods) — growing attach rate won’t deliver meaningful profit. Optimise pricing first.
5. Club without table service (self-service only)
Section titled “5. Club without table service (self-service only)”If you only have a vending machine or an unstaffed counter — the admin script lever isn’t available. Only lever is visibility and QR codes. Attach rate ceiling for self-service is significantly lower.
Parameters depend on your bar format, audience and margin. Formulas are frameworks — substitute your numbers.

Frequently asked questions
What attach rate is good for a PC club?
Depends on format. Full bar with food and drinks: 25–45%. Drinks and snacks stand: 15–25%. Vending/self-service: 8–15%. Focus on dynamics from your own baseline, not abstract benchmarks.
Why is the question 'anything from the bar?' so effective?
Most people don't order at the bar not because they don't want to, but because they don't think about it at checkout. The admin's question switches their attention. This is called a 'moment of decision' — creating the moment when the decision is made rather than deferred.
Does a combo need to be discounted?
A small discount (5–10% vs individual prices) improves combo conversion by 15–20%. But even an undiscounted combo works through 'full package' psychology: the client perceives an hour + drink as a standard, not two separate decisions.
How do you raise attach rate during daytime hours when it's traditionally zero?
Three levers: (1) a daytime combo with tea/coffee — the working audience buys hot drinks more readily than energy drinks; (2) a discount on a specific item only during daytime; (3) menu visibility. Morning audience has a different profile — needs a different combo.
Does bar placement affect attach rate?
Significantly. A stand near the entrance/register gives 8–12 pp higher attach rate than a stand in a corner. If physical relocation isn't possible — create a 'visual anchor': menu poster at the register + table cards at desks.
How do you calculate bar revenue contribution to overall club revenue?
Bar contribution = bar revenue ÷ total club revenue × 100%. In a healthy club with a full bar, this metric is 15–25%. If < 5% with a bar present — attach rate is critically low. Formula: Δ bar revenue = Δ attach_rate × sessions × avg bar order.
Should the bartender be trained to sell?
Yes, but differently from the admin. The bartender works with a client who is already at the stand and has already decided to buy. Their job is upsell (larger size, combo, add-on) — not the initial offer. The initial offer is the admin's job at session checkout.
How does the IZI mobile app affect attach rate?
In-seat ordering via the app — no need to stand up or queue. This reduces friction by ~80%. In clubs with high app adoption, attach rate is 8–15 pp higher than in clubs without the app. QR code on the table → app → order → delivery to seat.
What to do if attach rate grew but bar margin fell?
Check the combo pricing: if the combo discount is too steep, rising attach rate eats into margin. Recalculate: combo price should be no less than (rate + bar item) × 0.93. Also check whether supplier prices have risen — update costs in IZI item cards.
Can you grow attach rate without combos and scripts?
Only through improving visibility — menus at monitors, QR codes. That passively adds +3–5 pp. Admin script adds another +5–10 pp. Combo adds another +3–7 pp. Maximum effect comes from combining all three levers.
