| Software only | Your team configures prompts, tools, routing, QA, reporting, and exceptions. | The workflow is simple, the vendor integration is already enough, and someone internal can monitor calls. | The demo launches, but nobody owns failed transfers, bad summaries, tool timeouts, or staffing gaps. |
| Custom build | Your engineering team owns telephony, orchestration, integrations, monitoring, and release process. | You need deep product control, strict routing, custom APIs, or a reusable platform capability. | Engineering becomes the support desk for every prompt, carrier, calendar, CRM, and caller-experience issue. |
| Implementation partner | A partner designs the call flow, connects systems, sets escalation rules, and helps launch the workflow. | You like the platform direction but need help turning it into a production workflow. | If the partner leaves no operating playbook, the business can be stuck with software it cannot safely improve. |
| Managed voice-agent service | The partner helps build, monitor, QA, and staff human handoffs, callbacks, and exceptions. | The business needs automation plus people for urgent, uncertain, or high-value calls. | Scope must be written clearly so automation, Cebu support, and internal owners each know their boundaries. |
