A postclose transition services agreement, or TSA, defines temporary operational support that a seller or its retained organization will provide after ownership transfers. It should identify each service, its recipient, performance standard, duration, charges, required access, and exit process. Services might include financial reporting support, IT hosting, order processing, or data migration. Original filed agreements show that these commitments can have separate service schedules and end dates. [1] [2] Before agreeing, establish who can actually deliver the work and what the buyer must contribute. Have qualified transaction counsel review obligations, permissions, and remedies. Treat the TSA as a finite operational handoff, not an informal promise to remain available indefinitely.
Identify who provides support after the business changes hands
Start with the service provider's identity. Selling a business does not tell you which organization retains the people, systems, or premises needed for postclose support. Ask counsel to identify the parties bound by the TSA and distinguish those commitments from any separate consulting or employment arrangement involving the former owner. Build the delivery plan around resources that will remain available to the named provider after closing, not around the seller's preclose organization chart.
A TSA addresses continuing operations rather than the sale announcement or contingent purchase price. The QLT asset-sale agreement, for example, sits alongside the purchase agreement and separately defines seller services. The 3M and Solventum agreement expressly describes its services as transitional and limits them to specified purposes and service terms. [1] [2] Your operational question is therefore concrete: what cannot yet run independently on the buyer's side, and what support is the retained organization prepared to supply while that dependency is removed?
Turn broad service labels into a usable schedule
Avoid relying on labels such as finance support or IT assistance. Describe the actual activity, the systems involved, the business receiving it, and the expected output. The QLT agreement's schedule includes financial reconciliation information, website hosting, data migration, order processing, shipping, and customer service. These are examples from a particular transaction, not a checklist that every seller must accept. [2] For a distribution business, an illustrative service might be processing orders through a retained system while the buyer establishes its own order-to-cash process.
For each proposed service, record the request channel, delivery frequency, permitted users, source records, and explicit exclusions. Distinguish supplying historical information from preparing new analysis, and maintaining an existing workflow from building a replacement system. Name the buyer inputs required to perform the work. A schedule should also explain whether migration assistance is included or separately charged. QLT's agreement treats specified transition assistance as compensated services, illustrating why handoff work should not be left implicit. [2]
Match performance promises to staffing and capacity
A service-level agreement sets out agreed performance expectations for a service. Within a TSA, those expectations might be expressed in a schedule rather than a separate document. The 3M agreement uses scheduled service levels or key performance indicators where specified, with a defined internal-service comparison otherwise. QLT's agreement uses a historical service baseline that addresses scope, volume, care, and priority. [1] [2] Neither example establishes a universal service standard. Decide what the particular operation needs and what the provider can realistically deliver.
Ask the functional lead to explain how performance will be checked. For an illustrative IT service, distinguish availability from support response and restoration; those are different commitments. For order processing, define what constitutes a completed transaction and which exceptions need buyer decisions. Confirm coverage when retained employees leave or have competing responsibilities. If a requested standard cannot be supported by available staff, systems, or vendor arrangements, resolve that gap before signing rather than assuming the former owner will personally fill it.
Set service-specific end dates and dependency rules
Give each service its own start date, planned end date, and route to an earlier exit or an agreed extension. The original agreements reviewed here use service-specific schedules or periods rather than treating every operational dependency as identical. The 3M agreement limits extensions to specified routes and imposes contractual limits and increased charges. Those terms belong to that transaction; they are not a recommended default duration or price. [1] [2] Ask what happens if the buyer's replacement arrangements are not ready when your service ends.
Map dependencies before accepting partial termination rights. Hosting may support both reporting and order processing; removing it could interrupt services the buyer intends to retain. The 3M agreement specifically addresses entangled services that can terminate with the requested service. [1] For your transaction, record which services can end independently and which must migrate together. Require an authorized decision on extensions before the relevant notice deadline. Operational discussions about being almost ready should not substitute for the agreed process to change duration, scope, or charges.
Separate service charges from the full cost of remaining involved
Evaluate charges alongside the resources needed to deliver the service. The QLT agreement refers to employee hourly rates, scheduled charges, and defined third-party pass-through costs. The 3M agreement refers to scheduled service fees and provides a mechanism for certain vendor cost increases with notice and supporting evidence. [1] [2] These examples show possible contractual structures, not market pricing. Ask how your proposed charges account for staff work, vendor commitments, and migration support, and whether the retained organization can carry the resulting workload.
Agree on invoice detail and the approval process for extra work. Separate recurring operations from one-off migration, permitted vendor increases, and termination-related costs. Clarify minimum charges, partial-period billing, disputed invoices, and any non-cancellable external commitments. The 3M agreement expressly allocates certain documented external costs on termination. [1] Have the finance lead reconcile invoices to the signed schedule and authorized changes. Tax treatment and invoicing requirements depend on the entities, services, and applicable jurisdictions; use qualified tax advisers rather than assuming TSA receipts follow the treatment of sale proceeds.
Confirm permissions before promising access or data transfers
A TSA between buyer and seller does not itself settle a vendor's consent requirements. The 3M agreement addresses third-party permissions, services affected by missing consent, and alternative arrangements. [1] Review the actual hosting, software, logistics, and other supplier contracts involved in each service. Have the responsible contract owner and counsel establish whether the proposed postclose use is permitted, which party seeks any consent, and who bears the associated costs. Do not promise access first and investigate restrictions after closing.
Define which users may access which systems and records, for what purpose, and for how long. The operational plan should include approved accounts, access revocation, incident contacts, and a method to separate buyer information from retained-business information. Confidentiality, privacy, retention, and cross-border transfer obligations depend on the records and applicable law, so qualified counsel should review the specific arrangements. The 3M agreement includes confidentiality-related return or destruction provisions with stated exceptions and continuing restrictions. [1] Plan around the applicable obligations, not a blanket promise that every copy can immediately be deleted.
Give service administration an owner without handing over unlimited authority
Appoint an accountable transition lead on each side and a functional owner for every service. QLT's agreement provides for project managers on both sides; the 3M agreement establishes TSA oversight through a subcommittee. [1] [2] A smaller owner-led business can use a simpler structure, but it still needs a clear contact for unresolved requests, service failures, and buyer migration progress. Keep an issue record that identifies the service, evidence, responsible role, next decision, and contractual deadline.
Separate routine coordination from authority to alter the deal. A service owner may resolve an operational question without being authorized to extend the term, approve spending, disclose additional records, or waive a contractual right. Route those decisions to the designated human approvers. QLT's agreement requires mutually executed terms for additional services before those obligations take effect. [2] Use the signed TSA, service schedules, supplier permissions, and approved changes as the source of truth. Review actual delivery and unresolved dependencies regularly rather than relying on an informal stream of requests.
Define an exit the operations team can demonstrate
An end date needs a handoff plan. Identify the buyer's replacement system or provider, the required records, training responsibilities, and the person who accepts the transition. The 3M agreement assigns migration responsibilities and calls for an operational plan covering data, functions, milestones, and support. QLT's agreement provides for transition assistance and specified delivery of materials. [1] [2] Use these concepts to make your own exit measurable without assuming either contract's detailed terms apply to your sale.
For an illustrative order-processing handoff, the buyer's operations lead could check sample transactions, exception handling, and reconciliation before authorizing cutover. Define failure conditions, such as missing permissions, incomplete records, or unreconciled transactions, and an agreed escalation route. A failed test should trigger human review of the cutover or extension decision, not an undocumented continuation. At exit, record acceptance, terminate the relevant access, settle outstanding charges, and handle retained copies under the applicable obligations. Counsel should confirm which confidentiality, payment, liability, and dispute provisions survive termination.
Finish the seller's delivery plan before closing
Bring the schedule, staffing plan, cost assumptions, permission register, and exit milestones into one review before committing. Ask the operations lead to confirm deliverability, the finance lead to confirm charging mechanics, and qualified counsel to assess contract interaction, remedies, and liability under the governing law. If a critical service lacks resources, permission, or a workable handoff, resolve it explicitly through revised scope or another agreed arrangement. The desired result is a defined support commitment with an accountable owner and a credible route to independence.

Key Points
- Identify the actual postclose service provider and confirm which retained people, systems, and vendor arrangements can deliver each commitment.
- Define service outputs, performance standards, buyer inputs, exclusions, charges, and end dates in a usable schedule rather than broad support labels.
- Check vendor permissions and information access before promising continuity; assign responsibility for unresolved consents and alternatives.
- Track authorized scope changes, migration dependencies, and termination-related costs separately from routine operational requests.
- Make exit a demonstrated handoff with a human acceptance decision, access removal, final billing, and appropriate handling of retained records.
