Typing the same totals again and again
Prices, delivery fees and change are worked out by hand in every chat.
Sell in the chat. Skip the busy work.
SBK is an Android keyboard. It spots orders while you type, builds an itemised invoice from your catalogue in a few taps, and gets you paid by payment link, bank transfer or mobile money, in your own currency.

Selling in chats is busy work
Invoices made somewhere else
You leave the chat, open another app, copy the details back and hope nothing was missed.
Orders lost in long threads
Who asked, who paid and who still owes is buried in screenshots and voice notes.
Payments scattered everywhere
Mobile money, bank transfers and customers abroad each need different details, and follow-ups get forgotten.
From “can I get…” to paid, in six steps
Four business keys, right on your keyboard
Build an itemised invoice, quote or receipt from your catalogue and send it as a link in the chat.
Set a friendly payment reminder in two taps. SBK tells you when it's due.
Every customer moves from Asked to Quoted to Paid, so nothing slips.
See what you sold, who owes you and your best customers this week.
