A useful TSA finance cost benchmark starts from where finance sits in the bill: behind IT, but usually ahead of every other function, often 15 to 25 percent of the total. Finance costs what it does because the divested business ran its close, its treasury, and its reporting on the parent platforms, and those obligations cannot pause while the entity stands up its own. Controlling finance cost is a central part of disciplined TSA cost reduction.
Finance is expensive on a TSA because most carved out businesses never ran a complete finance function of their own. They booked transactions in the parent general ledger, paid suppliers through the parent accounts payable team, and closed their books inside the parent calendar. The finance you are buying often did not exist as a standalone capability before the deal.
That dependence makes finance both broad and continuous. Cash has to move, suppliers have to be paid, payroll has to be funded, and the books have to close every period without interruption. None of that can wait for a convenient moment, so the seller keeps providing it and keeps charging for it across the life of the agreement.
The benchmark figures here are indicative ranges across carve-outs, not fixed prices. The pattern that holds is the position: finance is consistently the second heaviest workstream after IT. A buyer who understands where finance cost concentrates has the second largest part of the transition bill in view.
The largest finance line is usually transactional processing: accounts payable, accounts receivable, and general ledger operations. These are high volume, daily activities, and the seller often charges them on a cost-plus basis tied to headcount or transaction counts. Because the work runs every day, the cost compounds quickly.
Buyers should ask how these charges are built. A per transaction or per invoice rate is easy to inflate when it carries allocated management overhead the carved out business will never use. The honest basis is the seller actual cost to run the process plus an agreed mark-up, and the buyer is entitled to see how that number was derived.
Transactional processing is also where the buyer can move first. Standing up an independent accounts payable and receivable capability is achievable well before the harder reporting and treasury work is done. Exiting these high volume services early removes a recurring charge and proves the new finance function can carry real load.
Most finance cost ultimately traces back to the parent ERP. The general ledger, the chart of accounts, and the period close all live there, and finance cannot fully exit the TSA until the business runs on its own instance. This is why finance and IT cost are linked: the ERP separation gates both.
The monthly and quarterly close adds a rhythm the buyer cannot ignore. Until the new finance team has completed a full cycle on independent systems, including consolidation and management reporting, the seller support has to stay in place. A buyer that rushes the cutover and then fails a close ends up paying for seller help twice.
This dependency is why finance lines often persist late into the agreement. Treating the ERP migration and the first independent close as the critical path for finance, rather than as separate IT and finance tasks, is the difference between a clean exit and a string of extension fees on every dependent service.
Treasury services, bank relationships, cash pooling, and payment execution, are a distinct finance cost that buyers sometimes underestimate. Opening independent bank accounts, repapering payment mandates, and moving off the parent cash management platform take time, and until they are done the seller controls the money movement and charges for it.
Tax and statutory reporting are tied to the fiscal calendar, which makes them stubborn. Filings, audits, and year end statutory accounts often cannot be cleanly handed over mid cycle, so the buyer may need seller support through at least one full year end. These are lower volume than transactional processing but they extend the tail of the finance TSA.
Because these obligations are calendar driven, they reward planning rather than speed. Mapping every statutory and tax dependency to its filing date lets the buyer schedule the exit around real deadlines instead of discovering them late, when the only option is an expensive extension on a service that should have ended.
Start by scoping each finance service against the actual cost to provide. Transactional processing rates, treasury fees, and reporting charges all deserve a clear cost basis, and the largest lines are where inflated allocation and excessive mark-up do the most damage. A benchmark only helps if the buyer uses it to challenge the seller number.
Sequence the exit around the two constraints that actually gate finance: the ERP separation and the fiscal calendar. Plan the migration and the first independent close early, and time the statutory and tax handovers to filing dates. Finance services should leave the TSA in a deliberate order, not drift to the contract end.
Then exit each service the moment the independent capability is proven. High volume transactional processing can usually go first, with treasury, reporting, and tax following as their dependencies clear. Managed this way, finance moves from a recurring second largest charge to a workstream the buyer retires on schedule and on its own terms.
Finance is usually the second largest workstream after IT, often in the range of 15 to 25 percent of total TSA cost. The exact share depends on how integrated the divested finance function was with the parent and how quickly the buyer can stand up an independent close, treasury, and reporting capability.
The biggest driver is dependence on the parent ERP and the shared transactional processes that run on it, including accounts payable, accounts receivable, and the general ledger. Treasury, payroll funding, statutory reporting, and tax compliance add further lines that cannot lapse during the transition.
Finance often cannot exit until the ERP is separated and a full reporting cycle has been completed on independent systems. Statutory and tax obligations are tied to fiscal calendars, so a buyer may need seller support through at least one year end close, which keeps finance lines live and accruing cost.
Scope each finance service against the actual cost to provide, plan the ERP and reporting separation early so finance exits on the buyer schedule, and sequence the exit around the fiscal calendar. Challenging mark-up on transactional processing and removing services as soon as the independent close is proven keeps cumulative cost down.
