Executive Summary

Small teams use personal phones for calls SMS and WhatsApp which breaks routing accountability and on-call coverage. Build a cloud telephony inbox that routes PSTN SMS and WhatsApp to the on-duty agent with schedules, role assignment and handoff logs. WhatsApp Business API and cloud telephony providers now expose programmable access to WhatsApp messaging and link it with PSTN numbers, making it feasible to consolidate channels into one routing layer. Travel and hospitality have rebounded post-pandemic and international clients prefer WhatsApp and SMS for real-time coordination, creating recurring high-frequency workflows (itineraries, last-mile vendor coordination) that justify a paid service. The source owner already purchased a business number which makes adoption friction low and shows buyers are ready to move off personal devices. Product focused on SME operators (travel DMCs, tour operators, small hospitality teams) that need a single purchased business number to handle PSTN calls SMS and the WhatsApp Business channel plus simple on-call scheduling and agent handoffs. Evidence from the source shows a single owner already bought a dedicated business number and receives frequent multi-channel inbound traffic from North America and local vendors, so speed-to-value comes from connecting that owned number to programmable voice SMS and the WhatsApp Business API, then adding a lightweight schedule and escalation layer. The data moat comes from accumulated routing rules, on-call schedules, response SLAs, and contact preferences per client which create product-specific heuristics for better routing over time.
