Building Materials Rewards Assessment — Full Reference Content
Identity — The Invisible Customer (0)
Cashbuild operates 322 stores across 5 countries with R11.5 billion in revenue. Zero customer data is captured. A builder spending R200,000 over 12 months is invisible.
A single phone number at the till changes everything. WhatsApp-based identity capture links every transaction to a profile without an app, a card, or a login.
Identity — Low Tier Recommendation
Start capturing identity tomorrow. One change: ask for a phone number at the till. Incentivise the first capture with R20 airtime via WhatsApp. No app required. No loyalty card. Run it in 5 stores for 30 days and measure how many unique customers you can identify.
Identity — Mid Tier Recommendation
You capture some identity but gaps remain on cash transactions. Add a WhatsApp opt-in at every till point. The incentive is small, R10-R20 airtime, but the data is permanent. Target 50% identity capture on all transactions within 90 days.
Identity — High Tier Recommendation
Strong identity capture. Now enrich the profiles. Link transactions into project timelines. Flag customers whose purchase pattern suggests a building project. A customer buying cement, then timber, then roofing over 3 months is a R200,000 relationship in progress.
Segmentation — The R200K Blind Spot (R729)
Cashbuild’s average basket is R729. But a project builder spending R200,000 over 12 months has a completely different need, frequency, and lifetime value than a R500 weekend buyer.
Without segmentation, the most valuable customer in retail gets the same experience as a first-time walk-in. Segmentation turns anonymous transactions into a relationship.
Segmentation — Low Tier Recommendation
You treat all customers the same. Start with two segments: project builders (3+ visits in 90 days with basket over R2,000) and retail walk-ins (everything else). Apply a different reward tier to each. Measure whether project builders increase visit frequency when recognised.
Segmentation — Mid Tier Recommendation
You have basic segmentation but it is not driving differentiated value. Create a contractor tier. Contractors who specify materials for multiple projects are multiplier customers. A R500 monthly fuel voucher for contractors spending over R50,000 per quarter costs less than losing them to a competitor.
Segmentation — High Tier Recommendation
Strong segmentation. Now automate triggers. When a customer’s purchase pattern matches a building project sequence, send a next-stage product recommendation via WhatsApp with a reward attached. Proactive segmentation drives the next purchase instead of waiting for the customer to return.
Lifecycle — The Project Gap (12 months)
A house build takes 12 months and follows a predictable sequence: foundation, structure, roofing, plumbing, electrical, paint, finishing. Each stage involves different products purchased weeks apart.
If you only engage at the till, you miss the opportunity to guide the next purchase, reward the next visit, and retain the customer for the next project.
Lifecycle — Low Tier Recommendation
You have no post-purchase engagement. Start with one trigger: 7 days after a cement purchase over R3,000, send a WhatsApp message with a R30 reward for timber or structural steel. Test whether the next-stage prompt drives a return visit within 14 days.
Lifecycle — Mid Tier Recommendation
You send promotions but they are not tied to the building journey. Map the 6 stages of a typical build (foundation, structure, roofing, plumbing/electrical, plastering, painting/finishing) and create a reward trigger for each stage transition. Test with 100 identified project builders over 6 months.
Lifecycle — High Tier Recommendation
Strong lifecycle engagement. Now add project completion rewards and referral mechanics. A customer who completes a build and refers a friend starting their own project is your lowest-cost acquisition channel. Reward the referral with R200 in lifestyle rewards and track the conversion rate.
Funding — The Supplier Model (20.9%)
Dis-Chem’s Better Rewards model shows that 140+ supplier brands co-fund rewards. Participating brands grew volume 20.9%. The retailer’s net cost approaches zero.
In building materials, cement, paint, roofing, and timber suppliers compete for shelf space and contractor loyalty. A supplier-funded reward tied to a specific SKU purchase gives the supplier verified sell-through data and costs the retailer nothing.
Funding — Low Tier Recommendation
You fund all promotions yourself. Approach your top 3 suppliers, cement, paint, and timber, with a simple proposition: R20 reward funded by the supplier, attached to their SKU, delivered via WhatsApp at point of sale. The supplier gets verified sell-through data. You get a funded reward. Run a 60-day pilot with one supplier.
Funding — Mid Tier Recommendation
You have some supplier involvement but it is not structured. Build a supplier co-funding framework: fixed cost per reward, verified purchase trigger, real-time sales data shared with the supplier. Dis-Chem’s model proves suppliers will fund rewards when they can see the uplift. Present the framework to your top 5 suppliers.
Funding — High Tier Recommendation
Strong supplier funding. Now add a banking partner. Approach Capitec, FNB, or a mobile-money provider about co-funding rewards on card or mobile-money transactions in your stores. The banking partner funds the reward from interchange revenue. Your cost drops to near zero.
Delivery — The Cash Customer Problem (Cash)
Most building materials customers pay cash and do not download retail apps. A programme requiring an app excludes the majority of your customers.
WhatsApp or USSD captures identity at the till via phone number and delivers a reward in under 5 minutes. No app. No card. No login. Works on any handset.
Delivery — Low Tier Recommendation
You cannot deliver rewards to cash customers. Start with WhatsApp. Customer gives phone number at the till. Cashier enters it into the POS or a simple tablet. Reward is delivered via WhatsApp in 5 minutes. No app. No card. Test in 3 stores for 30 days.
Delivery — Mid Tier Recommendation
You have a delivery mechanism but it is slow or limited to app users. Add WhatsApp as a delivery channel for all customers. Test instant delivery, reward within 5 minutes of purchase, versus your current mechanism. Measure redemption rates and repeat visit rates for both.
Delivery — High Tier Recommendation
Strong delivery. Now optimise the moment. Test delivering the reward while the customer is still in the store versus after they leave. An in-store reward with a next-purchase offer creates an immediate reason to add to the basket or plan the next visit.
Cost of Doing Nothing — Identity (0 data points)
Every transaction without identity capture is a lost relationship. Cashbuild processes millions of anonymous transactions per year. A project builder spending R200,000 over 12 months is invisible. Every month without identity capture is a month of revenue with no customer relationship attached.
Cost of Doing Nothing — Segmentation (R729 average)
An average basket of R729 hides a R200,000 project builder and a R500 weekend buyer in the same number. Without segmentation, your most valuable customers get no recognition, no differentiated service, and no reason to stay loyal. Every month they are treated as average is a month a competitor can win them.
Cost of Doing Nothing — Lifecycle (12 months)
A building project lasts 12 months. If you only engage at the till, you lose the customer between stages. A competitor who sends a next-stage product prompt with a reward attached captures the visit you missed. Every month without lifecycle engagement is a month of project revenue leaking to competitors.
Cost of Doing Nothing — Funding (100% self-funded)
Every reward you fund yourself is a cost. Every supplier-funded reward is free revenue with verified sell-through data attached. Dis-Chem proved 140+ brands will co-fund when they see the uplift. Every month without a supplier-funding model is a month of unnecessary margin erosion.
Cost of Doing Nothing — Delivery (No mechanism)
If you cannot deliver a reward to a cash-paying customer, your programme excludes the majority of your base. Every month without a WhatsApp or USSD delivery channel is a month your customers have no reason to identify themselves and no reason to return.
