Sound familiar?
Every independent mobile vendor owner we talk to runs into the same walls.
Paper cards don't work when you move
You pitch at different markets, parks, and events each week. Customers carry physical stamp cards and forget them at home — or lose them between your Friday and Monday pitches. Every lost card is lost loyalty data you'll never get back.
No way to tell regulars where you'll be
You're at Neighbourgoods on Saturday, Oranjezicht midweek, and a corporate office park on Fridays. Your regulars want to find you, but you're posting locations on Instagram stories that disappear in 24 hours. There's no reliable way to let your base know where you're trading.
Wifi and card machines are a nightmare
Half the outdoor markets have patchy connectivity. You can't rely on wifi-dependent loyalty systems when you're setting up at a park or street corner. And expensive card machine loyalty integrations assume you have a fixed retail footprint — which you don't.
What Lekka gives your mobile vendor
A digital stamp card that works offline
Customers scan your QR code at the cart and collect a stamp directly in their mobile browser. No app to download, no wifi connection needed on your side. The customer's phone does all the work — they scan, the stamp lands in their wallet, and their progress is saved automatically. When they hit your stamp target, they earn whatever reward you've set. The whole interaction takes about 10 seconds, and it works whether you're at a bustling market with zero wifi or parked at a corporate park with full signal.
Broadcast your location and specials
Once customers join your programme, you have a direct line to them. Trading at Oranjezicht this Thursday? Send a broadcast. Got extra vetkoek at 2pm? Broadcast a quick-sale special. Swapping your usual Friday pitch for a different location? Let everyone in your programme know. This is the single biggest unlock for mobile vendors. Your regulars don't have to guess where you are or check three different Instagram accounts — they get a notification when you're nearby or have something worth knowing about.
Visibility into who your regulars are
Your vendor dashboard shows you who's collecting stamps, how often they visit, and who's about to earn a reward. You'll know which customers show up at every market versus the ones who only pitch when you're near their office. For the first time, you'll have actual data on your customer base — not gut feel or paper receipts. Which days are strongest? Which locations bring the most new signups? Who are your top 10 regulars by visit count? It's all there.
A reward they'll actually work for.
You set the rules. Here's a popular structure for mobile vendors:

Does giving away a free coffee actually make sense?
Most mobile vendors know intuitively that loyalty programmes work — but few have actually done the maths. Here's what it looks like in rands.
| Average coffee sale priceFlat white / cappuccino | R45 |
| Revenue from 9 coffees | R405 |
| Cost of goods for 1 free coffeeMilk, beans, cup — not labour | ~R12–18 |
| Cost as % of 9-coffee revenue | ~3–4% |
| Alternative: paying for a new customer via Instagram adsPer new customer acquired | R80–200+ |
A free coffee after 9 costs you roughly R15 in actual ingredients against R405 in revenue — about 3.5%. Customer loyalty cards are one of the cheapest retention tools in existence. The real question isn't whether you can afford to run a loyalty programme. It's whether you can afford not to — especially when you're competing for foot traffic at crowded markets.
Why mobile vendors can beat the chains at loyalty
The big coffee chains have national loyalty apps — but they can't follow you from market to market. That's your advantage.
Your regulars have to travel to them. You travel to your regulars. A broadcast saying 'Now live at Century City today' brings customers to exactly where they already are. Fixed shops can't do that.
Most customers won't download another app for a mobile vendor they see once or twice a week. Lekka works in the browser — instant signup, no friction. Your signup rate will be higher than the chains because the barrier is lower.
Customers lose them between markets, or carry three different vendors' cards and forget which is which. Digital cards can't be lost, and customers can collect stamps from multiple vendors in one place — their phone.
Mobile vendors who embrace digital loyalty have a genuine competitive edge. You offer convenience (you come to them), personalisation (you know your regulars by face), and now you can match the chains on technology. That combination is hard to beat.
The most common loyalty mistakes mobile vendors make
Avoid these and your programme will work significantly better.
Forgetting to mention it
Your QR code is on the cart, but you never mention the loyalty programme verbally. Most customers won't notice a small printed card while they're ordering. Say it out loud: 'Are you collecting stamps with us? Scan here — you'll get your 10th coffee free.' Verbalising doubles signup rate.
Not broadcasting your location
You set up the stamp card and never use the broadcast feature. This is the most valuable tool for mobile vendors. A Monday morning broadcast ('Live at Century City today — usual pitch near Spar') brings regulars to you. Use it weekly at minimum, daily when your schedule changes.
Setting the stamp target too high
If customers need 15 or 20 stamps before earning a reward, the goal feels unachievable and they disengage. Mobile vendors should run tighter targets than fixed shops — 8 to 10 stamps maximum. Your customers might only see you twice a week at markets, so 10 stamps = 5 weeks. That's motivating. 20 stamps = 10 weeks. That's forever.
Hiding the QR behind the counter
The QR code needs to be visible and accessible. Best placement for mobile setups: a small laminated tent card on your service counter that customers can reach without asking, or stuck to the front panel of your cart where the queue forms. If they have to ask where the QR is, half of them won't.
Changing your programme rules too often
Mobile vendors sometimes panic and change their stamp target or reward mid-programme. Don't. Customers who were on 7/10 stamps now see 7/15 and feel cheated. Pick your structure, run it for at least three months, then adjust based on real data. Consistency builds trust.
