How Voice AI Vendors and Services Partners Should Scope the First Deal


A first partner-led voice AI deal goes wrong in a predictable place: the client, the services partner and the platform vendor each assume one of the others owns a piece of the work. The fix is a written scope with one discovery owner, one call type, a named owner for every workstream, vendor services only where the deal actually needs them, and services priced separately from usage.
This is the scoping path we would hand a partner before their first quote goes out. If you are the client, it is also the list of things to ask your partner to put in writing.
The partner should. The partner holds the client relationship, writes the statement of work, and will be the one fixing the agent in month three, so discovery has to produce answers the partner can deliver against.
The vendor joins discovery for a narrow set of questions: whether the client's telephony, compliance and volume requirements fit a standard plan or need an enterprise contract. Settle those before scope is written, not after the client has signed.
Discovery should come back with these answers in writing:
If the compliance or capacity answers point to custom terms, the vendor conversation moves earlier. On Retell, a custom MSA, DPA or BAA, SSO and role-based access control are listed on the Enterprise plan, not pay-as-you-go, per the pricing page. A deal that needs any of them is an Enterprise conversation from the start.
One call type, done well enough to expand. Picking the call type, and testing it on real calls, is covered in how to evaluate a voice agent platform before go-live. The scoping job here is drawing the line between phase one and phase two.
| Area | In the first deployment | Defer to phase two |
|---|---|---|
| Call types | One, with known volume | Every other call type the client mentions |
| Entry point | One number or one IVR transfer | Multiple lines, regions or brands |
| Systems | One system of record, through a built-in integration if one exists | Second and third systems, custom middleware |
| Escalation | One transfer path with business-hours rules | Skill-based routing across teams |
| Languages | The main caller language | Additional languages |
| Reporting | The success number agreed in discovery | Custom dashboards |
Two scoping checks change the size of the build.
Is the system of record a built-in integration? Retell's integrations page lists HubSpot, Salesforce, Microsoft Dynamics 365, GoHighLevel and Zoho CRM for CRM, Zendesk for support tickets, Calendly, Cal.com and GoHighLevel for scheduling, and Google Drive, Microsoft OneDrive and Notion as knowledge base sources. Anything else is a custom function calling the client's own API, which is development work and should be scoped as such.
Does the client keep their existing telephony? Retell connects to existing carriers through elastic SIP trunking or by dialing a SIP URI, and its docs include setup guides for Five9, Genesys Cloud, Amazon Connect and Avaya. A contact center integration involves the client's telephony team, so name that person in the scope.
Build in a test path from the start. Retell supports simulation testing with graded test cases, and agent versions with prod and staging environment tags, so a change can be tested on a new version before the prod tag, which the production number follows, is moved to it.
Bring the vendor in when the risk in the deal sits in the platform layer rather than in the client's business. Partners know the client's process; the vendor knows how its platform behaves at the edges.
Retell's pricing page lists Dedicated Implementation Support as an add-on to the Enterprise plan, alongside a named account manager and 24/7 support with a dedicated portal. Retell does not publish a price or a minimum deal size for that add-on, so treat both as questions for the vendor.
Signals that vendor involvement is worth the cost:
Signals the partner can deliver alone: a single location, a built-in integration, a new or forwarded number, and standard volume. Retell's pay-as-you-go plan includes full platform access with no commitment, which suits that shape of deal.
Write it as a table with one owner per row. Shared rows are where first deals stall.
| Workstream | Partner | Vendor | Client |
|---|---|---|---|
| Discovery and requirements | Owns | Answers platform-fit questions | Provides volumes, systems, approvers |
| Client contract and SOW | Owns | Signs | |
| Platform contract | Agree with vendor who holds it | Enterprise terms, if needed | |
| Agent design and build | Owns | Implementation support, if purchased | Approves script |
| Built-in integrations | Configures | Provides credentials | |
| Custom functions to client systems | Builds | Provides API access | |
| Telephony and numbers | Configures the agent side | Documents SIP setup; supports per plan | Carrier or contact center changes |
| Testing and go-live sign-off | Runs tests | Signs off | |
| First-line support to the client | Owns | Reports issues | |
| Platform incidents | Escalates | Owns, per plan support level | |
| Changes after launch | Owns | Requests |
Workspace setup decides much of what follows. Retell isolates agents, numbers, API keys, members, webhooks and billing per workspace, and roles are assigned per workspace. The operating detail, including billing attribution and support tiers, is in running voice AI for clients.
Price it separately from platform usage. The client should see three things: platform usage, a one-time build, and an ongoing management fee with a defined change allowance.
Usage on Retell is published: $0.07 to $0.31 per minute for voice agents on pay-as-you-go, with Enterprise on custom pricing. Whether usage passes through at cost or carries a markup is a commercial choice. The four models that hold up at renewal are compared in how agencies price AI voice agents.
Two rules for the first deal:
Retell's partner pages state what certified partners get: referrals of potential customers, a listing in the Solution Partner Directory, co-marketing for higher tiers, early access to new features (especially at higher tiers), and dedicated partner support. They do not publish commission rates, minimum deal sizes or professional services pricing. Agree these with your partner contact in writing:
Partners building on Retell can apply through the Solution Partner Program; applicants are assessed on technical skills, industry experience and their potential to add value to the program. Clients who want a partner to run the first deployment can filter the Solution Partner Directory by region, language and integration. Either way, agree the scope above before the first quote, then run one call type on real calls before you expand.
