The verdict in three sentences
The uncomfortable truth: most stores fail because of logistics and payment, not design. In 2026, 62% of stores without native mobile money stall and hidden delivery fees drive 41% of cart abandonment. Before launching in Kampala, run this go/no-go checklist — it is worth more than ten mockup iterations.
The 7 mistakes that kill a launch
None of these mistakes is aesthetic. All are operational and cost real sales. Here is their quantified 2026 impact.
| # | Mistake | 2026 impact |
|---|---|---|
| 1 | No native mobile money | 62% of stores stall |
| 2 | Hidden delivery fees | 41% cart abandonment |
| 3 | Poor product photos | -30% conversion |
| 4 | No return policy | -15% trust |
| 5 | Site untested on mobile 3G | Loss of mobile buyers |
| 6 | TTFB > 800 ms | Bounce before render |
| 7 | No social proof / reviews | Hesitation at payment |
The hierarchy is clear: fix payment, delivery and photos first. These three items explain most lost carts, long before any consideration of color or font.
The go/no-go checklist before launch
A launch is validated against technical thresholds, not a gut feeling. Here are the criteria to tick before opening sales.
| Criterion | Go threshold | Status to verify |
|---|---|---|
| Wave / mobile money active and tested | Real transaction successful | Mandatory |
| Delivery fees shown from the cart | Full transparency | Mandatory |
| Photos: 3+ per product, clean background | Consistent quality | Mandatory |
| Return policy visible | Dedicated page | Mandatory |
| Test on real mobile 3G | Full purchase flow | Mandatory |
| TTFB | < 800 ms | Measured |
| At least 3 reviews or social proof | Trust | Recommended |
If a single "Mandatory" criterion is unchecked, it is no-go: postpone the launch by a few days rather than burning your opening traffic on a broken experience.

Mini case study
Rama, who runs a ready-to-wear shop in Kampala, launches without native mobile money (cash on delivery only) and without shown shipping fees. In her first month, she gets 800 visits but only 18 sales, i.e. 2.25% conversion, with 41% of carts abandoned at the delivery step. She fixes it: Wave integrated, shipping fees visible from the cart, photos redone. The next month, at equal traffic, she reaches 41 sales (5.1% conversion), i.e. +128%. Adding mobile money and fee transparency alone more than doubled her revenue — without touching the design.
FAQ
What is the most costly mistake? The lack of native mobile money: 62% of stores without it stall. In 2026, a Wave or mobile money checkout is no longer optional in our markets.
Why is hiding delivery fees so damaging? Because a last-minute surprise is the top cart-abandonment reason (41%). Show the cost from the moment of add-to-cart, even if you build it into the price.
Do photos really matter that much? Yes: poor visuals cost up to 30% of conversion. Three sharp photos per product on a clean background are a non-negotiable minimum.
Do you really need to test on 3G? Absolutely. A large share of buyers are on slow connections; an unoptimized site (TTFB > 800 ms) loses them before rendering. Testing on real mobile 3G is mandatory.
Does a return policy change anything? Yes: its absence drops trust by 15%. A clear return and refund page reassures buyers and lifts conversion, especially on first purchases.
