Vendor-Customer Collaboration During Implementation: Shared Plans, Ownership and Go-Live Criteria

An enterprise implementation is a joint project. Your team brings the product expertise and the forward deployed engineers (FDEs). The customer brings the admins, the data, the security approvals and the people who will actually use the product. Neither side can reach go-live alone, yet many rollouts are run as if only the vendor has a plan. The customer gets a kickoff deck, a few emails and a status call every week, and blockers on their side come to light only when a date has already slipped.

Implementations go better when both sides work from a shared plan, know who owns what, follow an agreed rhythm of communication and agree on what "done" means before work starts. This guide covers how to set up vendor-customer collaboration during implementation, and what to look for in the tools that support it.

Why Implementations Stall on the Customer Side

Look at where a slipped rollout actually got stuck and the answer is often a customer-side dependency, not your engineering work:

• Missing inputs: SSO metadata, sample data files, API credentials or an admin console screenshot that no one on the customer side was asked to own.
• Approvals that sat in a queue: a security review, a data processing agreement or an architecture sign-off waiting on someone who didn't know it was urgent.
• Champions with no time: the person who bought the product is not the person who has to configure it, and the configuration work was never assigned.
• Different versions of the plan: the vendor tracks the plan in one tool, the customer keeps their own spreadsheet, and the two drift apart within weeks.

None of these are technical problems. They are coordination problems, and they are solved by making customer-side work as visible and owned as your own.

Build One Shared Implementation Plan

The foundation of collaboration is a single plan that both teams can see and update. A mutual implementation plan should include:

• Phases and milestones: for example kickoff, discovery, integration, validation and cutover, with target dates for each.
• Dependencies: which milestones can't start until another finishes, so a slipped date automatically shows its downstream impact.
• Customer readiness gates: the inputs and approvals the customer must provide before a technical step can begin.
• Information requests: a tracked list of the files, credentials and answers you need, each with an owner and due date.

Start every plan from a template that matches the deal type or segment. Templates make rollouts repeatable and stop each FDE from inventing a new structure. Quivly's Projects workspace works this way: templates set the milestones, owners and dates, and forms collect the files, screenshots and answers the team is waiting on. On Quivly's FDE rollout plan, slipped dates roll forward to dependent milestones, so both sides see the real impact of a delay right away.

Make Ownership Two-Sided and Explicit

Every task in the plan needs one named owner, and that owner can be on the customer's team. Vague ownership like "customer IT" or "the vendor team" is how tasks get dropped.

Map the roles on both sides

Before kickoff, agree on who plays each role:

• Vendor side: implementation lead or FDE, CSM, solutions or support engineer, and an executive sponsor for escalations.
• Customer side: project lead, technical admin, security or IT approver, power users for testing and training, and an executive sponsor.

Track engagement at the person level

An account can look active while the one person who has to approve SSO has never logged in. Track whether each key stakeholder is engaged, not just the account as a whole. Quivly's onboarding tracking works at the contact level and can detect when key stakeholders, such as the IT admin, the power user or the executive sponsor, haven't been activated, then trigger targeted outreach to each of them.

Set a Communication Cadence Both Sides Can Keep

Agree on the rhythm of communication at kickoff, write it into the plan and stick to it. A typical cadence for an enterprise rollout looks like this:

• Async updates as work happens: task changes, customer replies and approvals recorded on the project, so no one waits for a meeting to learn the status.
• A weekly working session: the implementation leads on both sides review open tasks, blockers and the next two weeks of milestones.
• A regular executive check-in: sponsors review progress against the plan, the risks and any decisions that need their authority.
• An agreed escalation path: who to contact, through which channel and how fast, when a blocker threatens a milestone.

Meet customers in the channels they already use. Requests sent through a shared chat channel or email get answered faster than ones that require logging into another tool. In Quivly Projects, requests go out through Slack, email and the portal, while tasks, customer replies and approvals stay on the project. Agents can turn a conversation into a proposed task, risk or blocker with the evidence attached, and a person still confirms it before it is applied.

Agree on Mutual Go-Live Criteria Up Front

Many implementation disputes come down to a single question: is it done? The vendor thinks go-live happened when the integration passed testing, while the customer thinks it happens when their team is using the product every day. Settle this before work starts by writing go-live criteria that both sides sign off on.

What good go-live criteria include

• Technical readiness: integrations live, data migrated and validated, SSO and access provisioned.
• Validation: user acceptance testing completed by named customer testers, with open issues triaged by severity.
• People readiness: admins and end users trained, and support paths documented.
• Business readiness: the first value event the customer bought the product for is defined and measurable.
• Sign-off: a named approver on each side confirms the criteria are met.

Tie these criteria to readiness gates in the plan so cutover can't be scheduled until they are met. For a deeper look at the first value event and how to measure it, see our guide on how to measure time to value.

Keep Both Teams Working From the Same Facts

Collaboration breaks down when each side has different information. If the customer reports that something is broken and your CSM, FDE and support engineer each have a different version of the story, trust erodes quickly. Three practices help:

1. One timeline per issue: link the related ticket, technical alert and customer conversation together so everyone sees the same history.
2. Two views of the same issue: engineers need technical detail, while the customer needs a clear, plain-language explanation and an expected resolution date.
3. Proactive updates: tell the customer about a delay or issue before they discover it themselves.

When Quivly detects a technical issue, it creates an FDE alert with full technical context and a CS alert with a plain-language summary and a suggested customer message, both linked to the same incident timeline. The CSM can send the update while the FDE works on the fix.

What to Look For in Collaboration Tooling

Whatever tools you use, check them against these questions:

• Can the customer see the plan and their own tasks without a long setup process?
• Can you collect files, credentials and answers on the project instead of in email threads?
• Do dependencies update automatically when a date slips?
• Can requests reach customers through the chat and email channels they already use?
• Does it track stakeholder engagement at the person level?
• Does the plan connect to usage, support and CRM data, so progress reflects what is actually happening?

When go-live is reached, collaboration doesn't stop. It moves to adoption. Our implementation-to-adoption handoff playbook covers how to structure that transition.
