The verdict in three sentences
Delivery tracking turns customer anxiety ("where is my parcel?") into trust and cuts support tickets by 30 to 50 %. Each notified stage (confirmed, shipped, on the way, delivered) costs a few cents by SMS or runs through the WhatsApp Business API, often richer and better accepted. The return is immediate: fewer calls, fewer failures, higher CSAT and more repeat orders.
Stages to notify and the right channel
Not every stage deserves the same channel. Here is a template split and its indicative 2026 cost.
| Stage | Recommended channel | Unit cost | Impact |
|---|---|---|---|
| Order confirmed | WhatsApp / SMS | ~1-3 US cents | Reassures instantly |
| Payment received | ~variable API | Trust | |
| Shipped | SMS + WhatsApp | ~1-3 US cents | Anticipation |
| On the way (rider) | WhatsApp (+ link) | ~variable API | Fewer calls |
| Delivered | WhatsApp / SMS | ~1-3 US cents | Closure + review |
SMS stays unbeatable for universal reach; WhatsApp allows links, proof-of-delivery photos and customer replies.
SMS vs WhatsApp Business API
The two channels are complementary. Here is how they compare.
| Criterion | SMS | WhatsApp Business API |
|---|---|---|
| Cost per message | ~1-3 US cents | Billed per conversation / template |
| Reach | Universal (any phone) | Smartphone required |
| Richness | Text only | Links, images, buttons |
| Open rate | Very high | Very high |
| Customer reply | Limited | Conversational |
| Proof of delivery | No | Yes (photo) |
A common strategy: WhatsApp by default, SMS fallback if the customer has no WhatsApp or does not reply.

Mini case study
Adjoa runs a store in Accra, 600 orders/month. Before, her team fielded about 90 support calls/month of the "where is my parcel?" type, roughly 30 hours of work. She sets up 4 automatic notifications per order (confirmed, shipped, on the way, delivered) at an average of GHS 0.4 each, i.e. 600 x 4 x 0.4 = GHS 960/month. Support tickets fall 45 % (from 90 to 50), freeing ~15 hours, and her CSAT rises from 4.1 to 4.6. The time saved and the repeat-order lift more than cover the GHS 960.
FAQ
SMS or WhatsApp: where to start? Start with WhatsApp for richness (links, proof of delivery) and keep SMS as universal fallback. Many stores combine both by customer profile.
How much does full per-order tracking cost? Budget roughly GHS 1.5 to 4 for 4 SMS notifications, or a per-conversation cost on the WhatsApp Business API. It is negligible against the cost of a support call or a failed delivery.
Does tracking really cut support calls? Yes, by 30 to 50 % typically. A customer informed at each stage no longer needs to call to learn where their order stands.
Can I include a live tracking link? With WhatsApp, yes: a link to a tracking page (status + map) further cuts questions and reassures on timing. It reads as genuinely professional.
When should I ask for a review? Right after the "delivered" notification, when satisfaction peaks. This timing maximises response rate and lifts your overall rating.
