The first shop

Built for one shop
before anyone else saw it.

One Kariakoo shop, one delivery, one problem repeated three times a day. That is where Storebook started.

“
I was photographing every IMEI into WhatsApp, then checking the invoice by hand, then typing every phone into an app. Twelve identical handsets, one at a time.
Owner's name
Shop name · Kariakoo, Dar es Salaam
To confirm
A delivery of forty phones used to take the whole morning. Now it is done before the tea goes cold.
Owner's name
Shop name · Ubungo
Sample
A customer came back four months later. I searched the IMEI and there it was — the date, the warranty, and who sold it to him. Five seconds.

Questions

What shopkeepers ask.

No runaround answers. Where something isn't built yet, we say so.

Do I need to install anything?
No. It opens in your phone's browser, and you can add it to your home screen.
Does it work without internet?
Yes, for scanning and selling. Changes sync automatically when the connection returns.
Can my staff see my buying prices?
Only if you allow it. Every permission is set per person.
What happens to my data if I stop paying?
Nothing is deleted. You can still export everything; selling and receiving pause until payment resumes.
Does it work on iPhone?
Yes. On iPhone the fast scanner isn't supported by the browser yet, so you photograph the label instead. Everything else works the same.
Does it work for products other than phones?
Today it is built around IMEI-tracked phones. Accessories are on the roadmap.
Can two people use it at once?
Yes. Everyone in the shop shares the same live data, updated within seconds.
