Most TSAs are quietly priced fifteen to thirty percent above what the buyer would pay on the open market. The cost is split across cost-plus mark-up, pass-through padding, bundled scope, extension fees, and stranded cost. Cost reduction is the discipline of finding each of those, line by line, and removing it.
A TSA is the price the buyer pays for continuity of operations after a carve-out. The price has five components, and each can be reduced through different work. Cost reduction is the umbrella term for the discipline of reducing each component to its rational level. It is not a discount conversation. It is an operating analysis with a contract amendment as its output.
The seller's pricing is built from a defensible baseline. Allocated cost, mark-up, pass-through, extension fee curve, and stranded cost are all set in the original draft. Each is justified internally on the seller side. None of them is absolute. The buyer who treats the original draft as fixed pays full freight. The buyer who treats it as the seller's opening position pays less.
Cost reduction is most powerful pre-signing because the contract is not yet signed and the seller still has commercial incentive to make the deal work. It is meaningful mid-TSA because actual consumption data lets the buyer challenge specific assumptions in the original draft. It is least powerful post-exit because the seller has no commercial reason to refund anything that was contractually owed.
The cost reduction work is not done by a finance team alone. It requires operating insight to know which services the buyer actually consumes, contract knowledge to know which clauses can be amended, and benchmark data to know what the alternative looks like in the market. The combination is what makes the work credible to the seller side.
Every TSA cost sits in one of five categories. Each category responds to a different intervention. Knowing which category each dollar belongs to is the first step in any serious cost reduction effort.
Cost-plus mark-up. The percentage uplift the seller charges on top of its cost base. Visible. Headline. Often the first number the buyer challenges. Not always the largest opportunity.
Cost base allocation. What sits inside the cost the seller calls cost. Allocated overhead, IT infrastructure share, management charges, facilities. A loaded cost base inflates the mark-up dollar value without raising the headline percentage. Often the largest hidden opportunity.
Bundled scope. Services the buyer does not need but the seller included in the catalog. Often dressed as a single line item with a flat fee. Removing them or unbundling them is straightforward when the buyer knows what it is consuming.
Extension fees. The premium the buyer pays to keep services running past the original exit date. Often the largest single line item on a TSA that slipped its exit. Best avoided through schedule discipline. When unavoidable, negotiated down through capped curves and seller fault carve outs.
Stranded cost. The run rate that survives past the TSA exit because the underlying source cost has not been removed. Software licences, allocated headcount, infrastructure share, overhead allocations. The category most often missed entirely.
A cost-plus pricing audit examines each line item in the service catalog and asks three questions. What is in the cost base? What is the mark-up percentage? And does the mark-up bear a reasonable relationship to market rates for the same service?
The cost base is where most undisclosed margin sits. Sellers vary widely on what counts as cost. A direct labour cost is straightforward. Allocated overhead, IT infrastructure share, facility share, and management charges all involve methodology decisions that the seller controls and the buyer rarely sees. A pricing audit either requires the seller to disclose the allocation methodology, or it benchmarks the resulting cost rates against market data for equivalent services.
The mark-up percentage is the second target. Industry norms vary. For high volume routine services the buyer should expect mark-up at or near zero, on the basis that the seller is providing transition continuity rather than commercial service. For specialised services in the ten to twenty percent range is defensible. Above twenty percent requires service by service justification, and most lines that started at thirty to forty percent come down on serious review.
The audit produces a counter pricing position by line item. Specific target rates, specific mark-up caps, specific allocation methodology requests. The output goes to the negotiation team as a working redline package, not as a generic benchmark deck. TSA renegotiation is the firm's package for mid-TSA pricing reset.
A seller-drafted service catalog typically contains eighty to two hundred line items. On most carve-outs, somewhere between ten and thirty of those are services the buyer does not actually need. Either the buyer already has the capability, or the equivalent capability can be stood up internally before close, or the service is a bundled add on the seller included by default.
Scope rationalisation runs catalog item by catalog item. Each line gets one of four positions. Keep as drafted. Reduce scope. Reprice. Or remove. The remove decisions are the largest unit of value because they eliminate both ongoing cost and exit work in one move.
The harder cases are bundled services. The seller wraps three or four discrete services into a single bundled line with a flat fee. Unbundling produces transparency and almost always produces savings. Each component is then priced and exited separately. Sellers resist unbundling because it surfaces the embedded margin in the bundle, but with serious pressure most bundles can be unwrapped.
A working scope rationalisation in the pre-signing window targets twenty to thirty percent reduction in catalog item count and ten to twenty percent reduction in monthly run rate. Mid-TSA the numbers are smaller, but a six week renegotiation can still produce eight to twelve percent savings on most TSAs that were not audited pre-signing.
Pass-through items are invoiced at third-party cost with no seller mark-up. That is the promise. In practice, many items the seller calls pass-through actually contain embedded fees of five to fifteen percent, dressed as administrative charge or allocated overhead.
A pass-through reset starts with an audit. The buyer requests documentation: invoices from the third-party provider, supporting cost detail, and the calculation that converts the third-party cost to the line on the TSA invoice. If the documentation shows true pass-through, the line is confirmed. If it shows embedded mark-up, the buyer has three options.
Option one: reclassify the line as a cost-plus service with the embedded fee disclosed as explicit mark-up, then negotiate the mark-up down. Option two: require true pass-through with documentation, with the seller's administrative cost moved to a separate flat fee. Option three: insource the third-party relationship directly, bypassing the seller as an intermediary. The right choice depends on the volume, the complexity, and how much value the seller actually adds in the middle.
Pass-through reset is often the single highest return work in a TSA cost reduction effort, because the dollar value is large and the seller's negotiating position is weak. The seller cannot defend an administrative fee that is not documented. Most pass-through resets land within four weeks of the buyer asking for the documentation.
Extension fees are the most expensive form of TSA cost. A standard curve escalates from one hundred ten percent of base in months one to three of overrun to one hundred fifty percent or more by month six. On a $1,000,000 per month TSA, that is $5,000,000 per year in excess premium if the entire catalog runs into extension.
The single largest determinant of extension fee exposure is whether the original exit ramp is realistic. Schedules that were set under deal pressure, without operating insight, almost always slip. Schedules that were set against operating reality, with workstream owners signing off on dates, slip far less. Schedule discipline is the cheapest form of cost reduction.
Where slippage does occur, the work is dual. First, accelerate the at risk workstreams to bring them back on schedule. Second, dispute the extension fee where the cause is on the seller side. A negotiated extension fee curve with seller fault carve outs makes both possible. Without the carve outs, the buyer pays the curve regardless of cause.
TSA exit acceleration is the firm's package for when the schedule is at risk and the extension fee curve is approaching.
Stranded cost is the category most often missed. It is the run rate that survives past the TSA exit date because the underlying source cost has not been removed. Allocated software licences, shared infrastructure, allocated headcount, overhead allocations. Each is a tail that runs as Newco operating expense after the TSA terminates, unless explicitly addressed.
A working stranded cost plan identifies each source pre-exit, assigns an owner, and sets a target removal date. Software licences either transfer, get re-licensed independently, or get eliminated. Infrastructure is migrated to Newco-owned capacity or to a third-party provider. Allocated headcount is either hired by the Newco or transitioned off the invoice. Overhead allocations are removed at TSA termination.
The buyer who treats TSA exit as a contract termination event leaves the stranded cost in place. The contract ends. The run rate continues. The Newco then operates with an inflated cost base that surfaces in the first quarter as a margin surprise. The buyer who treats TSA exit as an operating transition removes the source cost in parallel with the contract termination, and the Newco begins independent life at a clean run rate.
Stranded cost work typically begins around month twelve of an eighteen month TSA, six months before the planned exit. Earlier is acceptable but rarely necessary. Later is too late. Stranded costs is covered in detail in the glossary.
Cost reduction is not a single event. It runs on a calendar across the TSA lifecycle. The largest single opportunity is pre-signing. The second largest is around month four to six post-close, when consumption data is available. The third is around month twelve, when stranded cost work begins. The fourth is around month sixteen, when exit acceleration may be needed.
Most buyers run cost reduction once, often at the wrong moment. Pre-signing is skipped because the deal team is focused on the SPA. Mid-TSA is skipped because the operating team is consumed with stand up work. Stranded cost is missed because nobody is looking for it. Exit acceleration happens only after the extension fee invoice has already arrived.
A buyer who runs all four cycles on schedule typically captures three to five times the value of a buyer who runs one cycle at random. The work is not more expensive. It is better timed. Each cycle is short, six to ten weeks, with specific deliverables and specific governance committee outputs.
For PE firms with multiple active TSAs across portfolio, a portfolio retainer is structured exactly around this calendar. Continuous coverage, with focused interventions at each lifecycle point. Engagement models covers the structure.
On a poorly negotiated TSA, fifteen to thirty percent of annual TSA spend is often recoverable through scope rationalisation, pricing reset, and pass-through validation. On well negotiated TSAs the upside is smaller but still meaningful, typically in the five to ten percent range. Extension fee avoidance is separate and can be a larger absolute number.
Pre-signing is best, because the seller has not yet locked the contract. Mid-TSA around month four to six is the second best window, when actual consumption data is available and the seller is willing to amend. Post-exit recovery is rare.
Scope reduction (services the buyer does not need but the seller bundled in), pass-through reset (items invoiced as pass-through but containing embedded mark-up), and extension fee avoidance (a clean exit on schedule rather than slipping into the punitive curve). Mark-up rate reduction is often the smallest of the four.
Done right, no. A working cost reduction process protects critical service continuity, focuses on services with provable over scope or over pricing, and uses governance to handle changes. Done poorly, with broad scope cuts and aggressive pricing demands, it can disrupt service. The discipline matters.
Renegotiation is one tool inside cost reduction. Cost reduction also includes pre-signing leverage, exit ramp acceleration to avoid extension fees, stranded cost elimination, and ongoing service-level enforcement. Renegotiation is the contract change. Cost reduction is the broader programme.
