Customer retention

Customer retention is the set of actions and tools that increase the share of buyers who make repeat purchases from the same seller. It includes not only loyalty programmes, but also service quality, communications and delivery speed.

How customer retention works

Retention is built on repeatable buying behaviour and lifecycle management of the customer. The main idea: acquiring a new customer is expensive, so the seller's task is to turn a one-time buyer into a customer who buys regularly and has a high LTV (lifetime value).

Key stages in the process:

• Acquisition and first conversion — focus on order quality and customer experience.
• Onboarding after purchase — instructions, confirming value; the first three days after the order are critical.
• Triggered communications — request for reviews, reminders about replenishment, offers of complementary products.
• Loyalty and retention — discounts for regulars, subscriptions, personalised offers.

Formulas and metrics you should calculate regularly:

• Retention rate (for a period): (number of customers at the end of the period who bought previously) / (number of customers at the start of the period) × 100%. Example: of 1,000 customers in January, 280 made a repeat purchase by March — quarterly retention is 28%.
• Repeat purchase rate: share of customers who made >1 purchase in the selected period. On Kaspi.kz, for FMCG and cosmetics categories the figure is often 20–35% among active sellers; for electronics — 8–15%.
• LTV: AOV × average number of purchases per year × average margin × expected customer lifetime. Example: AOV 6,000 KZT × 1.5 purchases/year × 30% margin × 2 years = 5,400 KZT LTV.
• Churn: 1 − retention. If annual retention is 70%, churn = 30%.

Why retention matters for a seller on Kaspi.kz

There are three practical benefits:

• Saving on acquisition. Acquiring a new customer often costs 5–25 times more than retaining an existing one. For a seller in Kazakhstan this means lower ad spend on Google and social channels and a more stable margin.
• Profit growth. Well-known studies show that a 5% increase in retention can raise profits by 25–95%. For local businesses this means regular buyers form the core profitable base.
• Resilience to price wars. A loyal customer is less sensitive to competitors' prices if they have good service, fast returns and clear communication.

Specifically on Kaspi.kz there are features that improve retention effectiveness:

• The integrated Kaspi payment ecosystem (cards, Kaspi Red, installment payments) makes repeat purchases more convenient — sellers who enable these options record a 10–18% uplift in conversion and repeat orders, according to internal seller data.
• Logistics and delivery options on Kaspi.kz (Kaspi delivery partners, pickup points and parcel services) reduce friction for repeat orders: faster delivery, predictable costs and simple returns improve repurchase likelihood.
• Buyer trust and marketplace mechanics — visible seller ratings, reviews and the Buy Box logic — make it easier for trusted sellers to get repeat traffic.
• Marketplace data and recommendation opportunities allow targeted offers based on past purchases, which increases relevance of upsell and cross-sell campaigns.

Examples from Kaspi.kz sellers

Real-life practices that work:

• FMCG seller: launched subscriptions/autoreorders for household staples with a small discount for subscribers. Result — higher repeat rate and more predictable weekly revenue.
• Electronics seller: after selling a smartphone, automated a 7-day follow-up with accessory bundles (cases, chargers) and a 30-day check-in for satisfaction. This raised repeat purchases for accessories and reduced returns.
• Cosmetics shop: offered sample kits and a personalised replenishment reminder based on typical consumption cycles; combined with promo codes in the app this increased repeat purchase rate among first-time buyers.

Practical tips and a checklist for implementing retention

Start simple and iterate. A practical rollout plan:

1. Improve immediate post-purchase experience: confirm order and shipping within 24–72 hours, provide clear usage or care instructions and tracking details.
2. Automate triggered touchpoints: welcome/onboarding message, request for review 3–7 days after delivery, personalised cross-sell offers 7–14 days later.
3. Enable Kaspi payment features (Kaspi Red, installments) and delivery/return options to lower friction for repeat orders.
4. Segment customers by purchase frequency and AOV; target high-value cohorts with VIP offers and standard cohorts with automated promo codes.
5. Introduce subscriptions or recurring orders for replenishable goods, with flexible intervals and easy cancellation.
6. Use simple incentives to reactivate customers: time-limited discounts, bundles, or free shipping thresholds for the second purchase.
7. Measure and optimise: run A/B tests on messaging, timing and offers; track impact on retention and CAC payback.
