Checkout: remove every reason to abandon
Most abandoned baskets are abandoned at checkout, and the causes are consistent: unexpected costs appearing late, forced account creation, a long or confusing form, and too few payment options. A great checkout shows total cost including delivery early, offers guest checkout, keeps the form as short as possible, and supports the payment methods London shoppers expect — cards, Apple Pay and Google Pay, and increasingly buy-now-pay-later for the right products.
Mobile checkout deserves particular care, because that is where most abandonment happens. Auto-filled fields, large tap targets, and payment wallets that skip manual card entry can lift completion meaningfully. The discipline is to treat every field and every step as a potential exit and justify its existence. Shaving friction off checkout is often the single highest-return change available to an established London store.
