Many organisations we meet have capable IT teams. Some have already built a prototype assistant on a large language model. So when they ask us “why wouldn’t we just build this?”, it’s a fair question.
Our honest answer: you may well be able to build it. The question is whether building it, and then running it indefinitely, is the best use of your people.
Launch is the easy part
A working demo is quick to build. A customer-facing service that runs every day is a different job. After launch, someone has to own:
- Channels. Website, phone, WhatsApp, Instagram, Facebook, email and SMS each have their own connections, permissions and failure modes. Connections expire, platforms change their rules, and messages occasionally fail to send.
- Knowledge. Opening hours change, policies change, events move. Every answer has to stay right on every channel.
- Integrations and actions. Calendars, helpdesks and booking systems need careful permissions, and someone has to handle what happens when an action fails.
- Boundaries. What the assistant may and may not say, when it must hand over, and how sensitive topics are handled.
- Monitoring and evaluation. Whether conversations are being resolved, where answers fail, and what to fix next.
- Security and data. Separation of customer data, encrypted credentials, backups and change control.
- Support. A named team to call when something looks wrong.
None of that is unusual. It’s simply ongoing operational work, and it doesn’t stop.
The question to ask
So the question to ask internally is: if we built this, who would own and maintain it after launch?
If you have a team ready to run channels, knowledge, integrations, monitoring, evaluation, updates, support and reporting, building may be right for you. Many teams decide they would rather spend that time on the work only they can do.
What a fully managed service changes
With Sum Vivas, we build, deploy, maintain and manage the technology. You keep control of your information, your policies and your outcomes.
| We own | You own |
|---|---|
| The technical build, configuration and deployment | Your objectives, approved knowledge and business rules |
| Monitoring, updates, channel management, support and backups | Permissions, governance and approval of integrations |
| Routine service management and technical optimisation | Responding to escalations and decisions about outcomes |
You still have a hand in it: your teams give access, approve integrations and pick up the escalations the Assistant passes on. What you don’t carry is the job of operating the platform underneath.
Comparing total cost honestly
When you compare options, compare everything, not just a build estimate:
- The people needed to build, then to run and improve it, every week.
- Each channel’s connection and upkeep.
- Evaluation and reporting, so you can show it’s working.
- Security, data protection and change control.
- What happens when the person who built it moves on.
We are happy to work through that comparison with you against your real resources and alternatives. Sometimes building is the right call, and we’ll say so.
Where a managed service fits best
In our experience, a fully managed Digital Assistant fits best where there is:
- meaningful, repetitive demand;
- peaks, such as events, seasons or deadlines;
- several channels to cover;
- out-of-hours need;
- physical locations as well as digital ones;
- a need to measure outcomes.
It’s a weaker fit if you need a simple FAQ widget, already have something that works, or have decided to own AI capability in-house.
Individual customer deployments have recorded reported returns of approximately 4.7x to 5x under their applicable business cases. Results vary by deployment and calculation basis; these examples are not a guarantee of future performance.
