TSA Exit Acceleration
One program, four vendors, one outcome.

TSA exit vendor management is the discipline that turns three or four parties into a single program. The seller delivers the services. The systems integrator runs the cutover. The third-party vendors hold contracts that have to be transferred or replaced. The buyer's program director owns the result. This article maps the vendor governance model that disciplined buyers apply as part of the broader TSA exit strategy framework.
Every TSA exit has four vendor categories that the buyer has to coordinate. The seller, who is delivering the transition services under the agreement. The systems integrator, hired by the buyer to run the cutover and stand up the Newco target state. The third-party software and infrastructure vendors whose contracts sit underneath the services being transitioned. And the boutique specialists who handle narrow scope items like payroll cutover, banking transitions, or carve-out tax filings.
Each category has a different commercial relationship with the buyer. The seller is bound by the TSA. The systems integrator is bound by a statement of work with milestones and acceptance criteria. The third-party vendors are bound by their existing master agreements, some of which sit with the seller and some of which have already been assigned to Newco. The specialists are bound by short scope-of-work agreements.
Treating the four as one program is the discipline. Treating them as four separate engagements is the failure mode. When the systems integrator does not know what the seller has scheduled for next Tuesday, the cutover slips. When the third-party vendor cannot reach the buyer because every email goes through the seller, the contract assignment slips. When the payroll specialist depends on a data file from the seller that no one has scheduled, payroll day one is at risk.
The buyer's program director owns the integration. The PMO maintains a single integrated plan, a single risk register, and a single escalation path that crosses all four categories. The vendors meet weekly at a joint standup that the program director chairs. This is not optional, and it is not a meeting the seller chairs.
The seller is a vendor under the TSA, and the TSA is a commercial contract. The buyer's posture should be the same as with any commercial vendor. Performance against the service catalog. SLA against the agreed metrics. Invoices reconciled to actual usage. Change requests routed through the change control mechanism. Disputes raised through the formal process. The relationship is not adversarial. It is commercial.
Most buyers under govern the seller for the first sixty days, then over correct after the first invoice surprise. The disciplined approach starts with formal governance from week one. The monthly invoice review compares actual charges against the service catalog rate card and against the volume baseline. Variances above 5 percent are flagged and explained. Pass-through charges include the underlying invoice. Mark-up is calculated and verified.
The seller's program manager attends the buyer's weekly workstream meetings and reports against the buyer's plan. The seller's plan and the buyer's plan are reconciled in writing every two weeks. When the seller's internal priorities shift, the buyer hears about it the same week. The TSA gives the buyer the right to a defined level of service. The discipline of weekly status protects that right.
Service credits are claimed when earned. The buyer does not waive them. Even small claims maintain the discipline that the SLA is real. Extension fee negotiations start ninety days before they are needed, not on the day they are needed. The pricing leverage covered in TSA exit cost benchmarks shapes how those negotiations are framed.
The systems integrator is a buyer-side vendor with a statement of work. The buyer controls the scope, the budget, and the acceptance criteria. The integrator's contract is structured around milestones, not hours. Each milestone has an acceptance test, a dollar value, and a date. The buyer pays on acceptance, not on effort. This structure aligns the integrator with the buyer's outcome.
The integrator's program manager reports to the buyer's program director, not to the seller. The integrator's status reports go to the buyer first. The integrator's risk register feeds the buyer's risk register. The integrator's resource plan is reviewed weekly against the buyer's expectations. When the integrator's resources slip, the buyer knows immediately, not at the end of the month.
Change orders are the discipline that protects the budget. The integrator cannot expand scope without a written change order signed by the buyer. Every change order shows the dollar impact, the schedule impact, and the dependency impact. Many integrators try to expand through verbal agreements at workstream meetings. The buyer's program director documents and rejects these expansions in writing.
Quality is measured at each milestone. Acceptance criteria are absolute, not negotiable. A milestone that fails acceptance is not paid until the integrator remediates. The buyer's quality lead, not the integrator's, owns the acceptance test design. The integrator's commercial incentive aligns with quality when the milestones are real. The IT separation pattern that drives this is covered in TSA exit IT separation.
The third-party vendors are the layer that surprises most buyers. Behind every TSA service sits a stack of underlying contracts. Software licenses, infrastructure, telecom, facilities, professional services. Some are assigned to Newco at signing. Some remain with the seller and pass through under the TSA. Some require vendor consent that takes months to obtain. Mapping all of them is the first step.
The contract inventory is built in the first thirty days. Every contract underlying the TSA services. The counterparty, the assignment status, the renewal date, the termination notice period, the buyer's exit options. The inventory is reviewed with the seller and validated against the seller's contract database. Gaps in the inventory are filled before Day One, not after.
Vendor consent campaigns run in parallel to the TSA itself. For contracts that require consent to assign or to terminate, the campaign begins as soon as the deal is announced. The buyer writes to the vendor, explains the transition, requests consent, and proposes a transition plan. Vendors that are slow to respond are escalated to the buyer's procurement leadership. The negotiation posture is direct.
Renewals during the TSA period are managed by the buyer, not the seller. A contract that renews during the TSA is a contract where the buyer has commercial leverage if the renewal is structured as a transition to Newco. The buyer's procurement team runs these renewals as part of the exit. Renewals managed by the seller during the TSA tend to optimize for the seller's relationship, not the buyer's exit.
The weekly joint vendor standup is the integration mechanism. Sixty minutes, every week, at the same time. Attendees are the buyer's program director, the seller's program manager, the systems integrator's program manager, and any specialist vendor with active work that week. The agenda is fixed. The discipline is that everyone in the room hears the same thing at the same time.
The agenda has four items. Progress this week against the integrated plan. Dependencies between parties that are at risk. Decisions that are needed this week to keep the plan on track. New risks identified by any party. Each section runs to a defined time box. The output is a single integrated status that the buyer's PMO publishes within 24 hours.
The decisions made in the joint standup are decisions about the integrated program, not about any individual vendor's contract. Contract level decisions are handled bilaterally between the buyer and the relevant vendor outside the joint forum. This keeps the joint standup focused on execution and protects the commercial relationships from being negotiated in front of competitors.
The joint standup is not a status meeting that the seller controls. It is a buyer-chaired forum. The buyer's program director sets the agenda, runs the meeting, publishes the notes, and tracks the actions. The vendors attend as participants. The cultural signal matters. The buyer is the customer, and the buyer is running the program.
Committee structure, meeting cadence, escalation paths, and the discipline that keeps the buyer in control.
