The verdict in three sentences
A one-page financial model beats a 30-slide deck nobody reads. For an online store, everything hinges on four numbers: setup cost (GHS 3,000-10,000), gross margin (25-45%), CAC, and break-even orders per month. Add MoMo settlement timing and you have a clear view of your cashflow.
The setup cost of an online store
Before your first sale, you invest in the platform, stock and visibility. Here are 2026 orders of magnitude.
| Item | Estimated 2026 cost | Note |
|---|---|---|
| E-commerce site (Starter) | GHS 3,000 - 10,000 | Catalogue + MoMo |
| Initial stock | GHS 2,000 - 12,000 | Depends on niche |
| Packaging / logistics | GHS 500 - 1,500 | Boxes, labels |
| Launch ads | GHS 1,000 - 3,000 | Meta/Google month 1 |
| Registration fees | GHS 100 - 300 | RGD + TIN |
| Total startup | ~GHS 6,600 - 26,800 |
A lean store using dropshipping or make-to-order sharply reduces the stock line but increases delivery time.
Unit economics and break-even
Profitability plays out order by order. Here are the typical unit economics of a GHS 180 order (order of magnitude).
| Element | Amount | % of price |
|---|---|---|
| Selling price | GHS 180 | 100% |
| Product cost | GHS 108 | 60% |
| Gross margin | GHS 72 | 40% |
| MoMo fees | ~GHS 3 | ~1.5% |
| Delivery cost | GHS 18 | 10% |
| Amortised CAC | GHS 12 | ~7% |
| Net margin / order | ~GHS 39 | ~22% |
If your monthly fixed costs (maintenance, ads, hosting) are GHS 1,800, your break-even is 1,800 / 39 = ~46 orders/month. Beyond that, each order is profit.
12-month projection and MoMo cashflow
The cashflow trap: settlement timing. Some MoMo settlements and bank transfers take 1-3 days to reach usable funds. Plan for this gap between collecting and actually having the cash, especially if you reinvest immediately into stock. A 20% monthly growth in orders is ambitious but reachable with a good acquisition mix; reinvest 40-50% of net margin into stock and ads while the LTV/CAC ratio stays healthy.

Akua launches a fabrics store in Accra with a store at GHS 6,000. Average order GHS 180, net margin 22% or about GHS 39/order. Fixed costs GHS 1,800/month, break-even 46 orders. In month 3 she does 80 orders: (80 x GHS 39) - GHS 1,800 = about GHS 1,320 profit. She reinvests GHS 600 in ads and reaches 120 orders in month 4.
FAQ
How much does it cost to launch an online store in Ghana in 2026?
An order of magnitude of GHS 6,600-26,800 all-in (site, stock, ads, registration). A Starter site with MoMo starts around GHS 3,000-10,000.
What gross margin should I target to be profitable?
Aim for 25-45% gross margin depending on the niche. Below 25%, delivery and acquisition costs make profitability very hard.
How do I calculate my break-even?
Divide monthly fixed costs by net margin per order. With GHS 1,800 in costs and GHS 39 margin, break-even is about 46 orders/month.
Does MoMo settlement timing affect my cashflow?
Yes. Some settlements take 1-3 days to reach usable funds. That gap matters when you reinvest immediately into stock.
Do I need a large stock to start?
Not necessarily. Make-to-order or dropshipping reduce initial stock at the cost of longer delivery. Adapt to your niche and cashflow.
