SMS invoicing for Botswana SMEs – no app for customers, tiny data for you.
Botswana SMEs cannot afford subscription-based SaaS tools due to exorbitant internet and data costs.
BwaBill lets you create and send invoices via SMS directly from a lightweight web dashboard that caches everything locally. Customers reply via SMS to pay/confirm, integrating with local mobile money like Orange Money. Dashboard uses <500KB per session, solving data cost pains with SMS fallback.
