Glossary

The vocabulary
of independent-shop memberships.

A working glossary of the words, metrics, and mechanics that show up when you start running a paid membership programme. Written for shop owners, not SaaS analysts.

Membership Fundamentals

Subscription membership: A paid monthly subscription a customer buys from an independent business in exchange for guaranteed perks — typically a daily coffee, a monthly blowdry, or a weekly bouquet. The customer pays upfront on a recurring schedule. The business earns predictable recurring revenue before the customer walks in.
Membership platform: Software that lets an independent business launch and run a paid subscription membership programme. Handles signup, billing, wallet pass issuance, perk redemption, and payouts — without requiring developers, custom apps, or new hardware. PerkClub is a UK membership platform built specifically for independent shops.
Perk: A specific benefit a member receives in exchange for their monthly fee — for example, one free hot drink per day, a 10% discount on food, priority booking, or a birthday upgrade. Perks should be concrete (one drink, not 'discounts'), capped where margin matters, and meaningful enough to drive renewal.
Entitlement: The set of rights a member has under their plan — for example, '1 hot drink per day, 10% off pastries'. Entitlements are typically expressed as item categories with usage caps (per-day, per-week, per-month). They define what staff are allowed to redeem at the counter.
Membership tier: A named plan within a membership programme — for example, 'Daily Grind' at £30/month and 'Weekend Warrior' at £18/month. Most independent shops run one or two tiers. Multi-tier programmes are useful when customers split between high-frequency regulars and lighter users.
Founding member: An early member recruited during a programme's launch phase, usually with a small ongoing perk or discount in exchange for their early adoption. Founding members normalise the membership for everyone watching and are typically among the highest-LTV cohorts in any programme.

Pricing & Revenue

Recurring revenue: Predictable income that repeats on a fixed schedule — typically monthly. For independent shops, recurring revenue smooths quiet weeks (rainy mornings, January, school holidays) and lets owners plan stock, hire staff, and invest with confidence rather than guessing each week.
MRR (monthly recurring revenue): The total predictable revenue a business earns each month from active subscriptions. Calculated as (active members × average plan price). MRR is the most useful single metric for a membership-led shop because it reflects revenue that lands whether or not customers walk in this week.
ARR (annual recurring revenue): Annualised recurring revenue — typically MRR × 12. For an independent shop with 50 members at £30/month, ARR is £18,000. ARR also forms the basis of any sale or valuation: a buyer of an indie shop will typically pay a multiple of ARR for the membership book.
LTV (lifetime value): The total revenue a single member generates across their full membership. Calculated as (monthly fee × average tenure in months) plus any extra spend on add-ons. For UK independent coffee shops, member LTV typically lands at 12–18 months × £30/month plus 15–25% incremental ticket spend.
Churn: The percentage of members who cancel within a given period (usually monthly). Healthy independent-shop membership programmes run 3–7% monthly churn after month three. Higher churn usually signals a perk-mix problem (members aren't getting value) or a delivery problem (the product isn't consistent).
Renewal rate: The percentage of members who continue past a renewal point — most usefully measured at month 3, month 6, and month 12. Healthy benchmarks for UK independent shops: ≥80% at month 3, ≥70% at month 6, ≥55% at month 12. Below these, the membership offer needs revisiting.
Transaction fee: The per-payment cost a payments processor charges. PerkClub charges 1.5% + 20p per transaction, which covers Stripe's processing cost. On a £30/month membership that's roughly 65p per member per month — significantly lower than typical card-machine rates.
Usage cap: A daily, weekly, or monthly limit on how many times a member can redeem a perk — e.g. '1 hot drink per day' or '4 cuts per year'. The cap is the single largest economic lever in any membership product because it bounds the worst-case cost of a heavy user while leaving the offer attractive.

Customer Experience

Wallet pass: A digital card stored in a phone's native wallet — Apple Wallet on iOS, Google Wallet on Android. PerkClub issues a branded membership pass to every member. The pass lives next to bank cards, never needs the customer to download an app, and is scanned at the counter to redeem perks.
Apple Wallet: Apple's native digital wallet on iOS, where iPhone users store boarding passes, transit tickets, loyalty cards, and bank cards. PerkClub issues iOS membership passes directly to Apple Wallet — no separate app needed. Members add a pass by scanning a QR code; the pass appears alongside their other cards in seconds.
Google Wallet: Google's native digital wallet on Android (and supported on Wear OS), the Android-equivalent of Apple Wallet. PerkClub issues Android-native membership passes directly to Google Wallet via the same QR-code signup flow used for iOS — no separate Android app.
No-app-required (loyalty): A loyalty or membership programme that runs entirely through the phone's existing wallet — Apple Wallet or Google Wallet — instead of asking customers to download a separate app. Removes the largest historical friction in customer-side loyalty adoption. PerkClub is built around a no-app model.
QR signup: The PerkClub join flow: a printed QR code at the counter (or on receipts, signage, or the website) opens a branded membership signup page. The customer picks a plan, enters payment details, and saves a wallet pass. The whole flow takes around 30 seconds end-to-end.
Redemption: The act of a member claiming a perk at the counter. Staff scan the member's wallet pass on the kiosk, see what the member is entitled to, and tap to confirm. A redemption typically takes a few seconds and updates the member's usage caps in real time.

Operations

Kiosk: PerkClub's browser-based redemption screen for staff. Runs in any modern browser on any phone, tablet, or laptop the shop already owns — no special hardware, no app to install. Staff scan a member's wallet pass, see their entitlements and remaining caps, and confirm redemption.
Merchant dashboard: The web-based control panel where shop owners design memberships, view active members, track MRR, monitor redemptions, and manage payouts. The dashboard is the management surface; the kiosk is the counter-side surface; together they cover the full operations of a membership programme.
Merchant: The business running a membership programme on PerkClub — for example, an independent UK coffee shop, barbershop, or salon. The merchant designs the membership, sets pricing, and receives weekly Stripe payouts. PerkClub is built specifically for independent UK merchants.
Smart notifications: Automated, transactional emails that PerkClub sends on the merchant's behalf — welcome confirmations, payment receipts, perk-expiry reminders, and renewal nudges. These are deliberately limited to genuinely useful messages, not promotional broadcasts.
Multi-location support: The ability to run a single membership programme across multiple shop locations under one merchant account. Members can redeem at any participating shop. Available on the PerkClub Max tier. Useful for small chains and multi-site independents.

Comparisons & Alternatives

Loyalty programme: A scheme that rewards customers retroactively for spending — typically through stamp cards, points, or discounts. Loyalty programmes are reactive (they kick in only when a customer chooses to come back). Subscription memberships are structural (revenue lands whether or not the customer visits this week). The two models look similar but operate on opposite economic logic.
Stamp card: A retroactive loyalty mechanic — paper or digital — where customers earn stamps for purchases and redeem a freebie after filling the card. Cards are widely recognised but generate no upfront revenue, get lost, and reward customers after the fact. Increasingly replaced by paid subscription memberships in independent UK retail.
Points-based loyalty: A loyalty model where customers earn points per pound spent and redeem points for rewards (typically discounts). Points-based programmes add accounting overhead, depend on customers remembering balances, and have low real redemption rates. Subscription memberships avoid this complexity by making the perk concrete and the revenue contractual.
Discount app: A third-party platform that drives footfall by offering customers discounted prices — for example, Too Good To Go for surplus food, or Groupon-style vouchers. Useful for filling specific quiet windows, but trains customers to wait for sales and trades margin for traffic.
Club Pret: Pret A Manger's UK coffee subscription — a £30/month plan giving members up to five drinks per day. Club Pret normalised the coffee-subscription mental model for UK customers and is the leading edge of the chain-driven shift toward subscription loyalty. PerkClub gives independent UK coffee shops a comparable subscription product without the corporate overhead.
Coffee subscription: A monthly recurring payment that entitles a customer to a defined set of perks at a coffee shop — most commonly one or two hot drinks per day plus discounts on food. UK independent coffee shops typically price coffee subscriptions at £25–£35/month. See PerkClub's coffee shop guide for design and pricing detail.

Technology & Payments

Stripe: The payments processor PerkClub uses for recurring billing and merchant payouts. Stripe is PCI Level 1 certified — the highest-tier security standard in the payments industry. PerkClub never stores card details; Stripe handles all card data and pays merchants out weekly to their UK bank account.
PCI Level 1: The highest tier of PCI DSS certification for payment-card data security. Stripe (PerkClub's payments processor) is PCI Level 1 certified, which means card data is handled with the same standard the largest payment processors in the world meet. PerkClub does not store card details on its own servers.
Payouts: Automatic weekly transfers from Stripe to the merchant's UK bank account, covering all subscription payments collected the prior week minus PerkClub's transaction fee. Payouts arrive on the same day each week, which lets shop owners time wholesale orders and payroll against a known income event.
JSON-LD: A structured-data format Google and AI engines use to understand a page's content. PerkClub embeds rich JSON-LD across the marketing site (Organization, SoftwareApplication, FAQPage, HowTo, BlogPosting, DefinedTermSet, and more) so that AI engines can accurately summarise, cite, and recommend our content.
Rolling 30-day contract: PerkClub's standard contract — a month-by-month subscription with no minimum term and no cancellation fee. Merchants can cancel any time and remain active until the end of their current billing period. Designed so that retention reflects the platform working, not lock-in.
Speakable markup: A Schema.org property that flags specific page sections as suitable for voice-assistant readout. PerkClub marks key answers with `data-speakable` and Speakable JSON-LD so that voice-driven AI assistants can read concise, accurate definitions aloud rather than improvising.
GEO (generative engine optimisation): The practice of optimising a website so that generative AI engines (ChatGPT, Gemini, Perplexity, Claude) accurately summarise, cite, and recommend it. GEO blends classic SEO (technical hygiene, structured data, page speed) with new disciplines (canonical answers, llms.txt, AI-readable knowledge graphs).
