Checklists for Launching Mixed-Brand IT Deployments

When your IT rollout involves multiple OEMs, VARs, MSPs, and white-label teams, field conflicts aren’t just possible—they’re inevitable. Competing priorities, clashing processes, or finger-pointing during outages can derail timelines, hurt client confidence, and lead to costly rework.

But with the right systems in place, you can turn vendor conflict into an opportunity for stronger coordination and accountability. Field vendor mediation is no longer optional for national rollouts—it’s an operational necessity.

At All IT Supported, we’ve worked with enterprise clients across healthcare, finance, and logistics to resolve hundreds of vendor-on-vendor issues in the field. Here’s what we’ve learned about navigating IT field vendor mediation without losing project control.

The Anatomy of Vendor Conflicts During Deployment

Common Scenarios Where Field Conflicts Arise

• Access overlap: Two vendors scheduled at the same site, same time, fighting over install space.
• SLA collision: One vendor misses a task, causing downstream vendors to delay their own delivery.
• Asset ownership disputes: Confusion over which party owns or configures a device on site.
• Competing documentation standards: Each team insists their ticketing format or field report is the “official” one.
• Scope ambiguity: Lack of clarity on which vendor is responsible for which deliverable.

Left unaddressed, these issues snowball into trust issues and missed milestones.

Why You Need a Vendor Mediation Playbook

Without a clear protocol, field conflicts escalate quickly and drag executive teams into low-level firefighting. A strong mediation strategy:

• Prevents timeline disruptions
• Maintains SLA compliance
• Protects customer satisfaction
• Keeps accountability clear
• Reduces technician turnover due to onsite friction

Proactive conflict management doesn’t mean being soft—it means staying in control.

Key Elements of a Vendor Mediation Strategy

Establishing Roles Before Dispatch

Every Statement of Work should clearly state:

• Primary vendor (who controls physical site access)
• Dependent vendors (who follow lead or support)
• Client-authorized escalation path (who resolves disputes onsite)

This eliminates ambiguity before techs are even deployed.

Mandating Onsite Lead Hierarchy

Designate one tech as the Lead Onsite Coordinator for each dispatch:

• They log arrivals/departures
• Control checklist flow
• Mediate access and priority if teams clash
• Escalate back to project managers with documentation

This person doesn’t have to be from your organization—but the role must exist.

Shared Ticketing and Pre-Check Communication

Use a unified dispatch ticketing system or ensure tickets are shared 24–48 hours before dispatch. Include:

• Site maps and access notes
• Other vendor schedules
• Equipment handoff protocols
• Emergency escalation contacts

This avoids the “I didn’t know you’d be here” problem that starts most field conflicts.

Field Conflict Resolution Protocol: What to Do When Tensions Rise

Step 1: De-escalate Onsite Immediately

Train all vendors to:

• Avoid public arguments in front of the client
• Pause installation and secure hardware
• Call the Lead Onsite Coordinator
• Use neutral language in incident logs

The goal is containment, not blame.

Step 2: Log Everything in Real Time

Use mobile audit tools or shared apps to capture:

• Timestamped issues
• Photos of disputed equipment or setups
• Text logs of disagreements
• Any client or third-party involvement

This ensures facts, not feelings drive resolution.

Step 3: Escalate Internally First

Avoid looping in the client unless absolutely necessary. Use your internal project manager or escalation contact to mediate across vendors using the SOW and original scope agreements.

When All IT Supported mediates multi-vendor field rollouts, our PMs resolve 95% of issues without bothering the client—preserving trust and pace.

Step 4: Reset Deliverables and Document Rework

If delays or changes are required:

• Adjust timelines in your dispatch portal
• Notify affected teams with revised SLA timers
• Include a conflict resolution summary in field reports
• Log which vendor caused the disruption (for accountability)

This protects future billing and audits.

Proactive Tactics to Prevent Future Conflicts

Use Cross-Vendor Kickoff Briefings

Before any rollout, hold a kickoff call with all vendor leads to align on:

• Shared goals
• Access rules
• Communication channels
• Escalation protocols

Reiterate that the project’s success > vendor ego.

Introduce Conflict Clauses in Contracts

Insert language that:

• Requires cooperation with other vendors
• Bans onsite disputes in front of clients
• Holds vendors responsible for delays caused by internal misalignment

It’s easier to enforce boundaries when they’re signed in advance.

Choose Vendors with Conflict Management Training

Some white-label teams are better trained than others. Ask potential partners:

• “How do you handle overlapping scopes?”
• “Have you ever had to step aside for another vendor?”
• “What’s your process for resolving site-level conflicts?”

At All IT Supported, our white-label techs are trained in conflict-averse deployment techniques—from calm escalation to non-verbal cue reading.

When to Replace a Vendor Over Field Conflicts

Not all vendors are built for collaboration. If a team repeatedly:

• Fails to coordinate
• Disrespects other vendors onsite
• Blames others in post-deployment reports
• Damages client trust

…it may be time to part ways.

Use post-project reviews to evaluate vendor compatibility—not just technical execution. A vendor who plays nice will save you more in the long run than one with perfect install speed but constant drama.

Better Field Mediation Starts with Better Processes

Vendor conflicts in the field don’t have to derail your IT projects. With clear expectations, defined roles, and fast escalation paths, you can keep vendors in sync—even in high-pressure deployments.
