Short Answer
Not every claim for all remaining fees is automatically valid—or automatically invalid.
The answer depends on the contract, the reason for termination, the governing law and what the claimed amount actually represents.
A useful exit calculation separates:
earned fees → unavoidable committed costs → genuine loss → contractual termination charge
rather than treating every remaining monthly fee as one undifferentiated debt.
Why This Matters
A recurring service agreement may have a modest monthly charge.
But if termination triggers payment of every remaining fee for the rest of a multi-year term, the exit cost can become far larger than the value of the remaining service.
This often becomes important where performance is poor, the business closes or restructures, the supplier is being replaced or the service is no longer needed.
Management may believe it can terminate on notice while the contract creates a very different economic consequence.
Typical Scenario
A customer wants to terminate a multi-year maintenance, technology or outsourced-service agreement.
The provider says:
“You must pay every remaining monthly fee through the original end date.”
The first question should not be only:
“Can they do that?”
It should be:
“What does each part of that claimed amount represent?”
Practical Analysis
01Separate accrued fees from future services.
Completed services and undisputed invoices are different from charges for work that will never be performed.
02Identify genuine committed cost.
The provider may have non-cancellable software, equipment, mobilisation or third-party costs. Ask for evidence rather than assuming those costs equal all remaining contract revenue.
03Check the termination route.
Termination for convenience is different from termination because the provider materially breached the agreement. Read the future-fee clause together with cure rights, service standards and termination-for-cause provisions.
04Characterise any fixed exit payment.
It may be a buyout amount, agreed damages, cost reimbursement or a contractual penalty. Where Thai law applies, section 383 of the Civil and Commercial Code allows a court to reduce a disproportionately high contractual penalty.
That does not mean every termination payment will be reduced. The legal character and proportionality of the clause matter.
05Consider avoided costs and real loss.
If the provider no longer needs to incur labour, travel, materials or third-party charges, gross remaining revenue may not equal the actual economic loss.
06Check standard-form terms where relevant.
Thailand’s Unfair Contract Terms Act may be relevant in qualifying arrangements. The application is fact-specific, so it should not be assumed to invalidate every one-sided business-to-business clause.
07Negotiate the release, not only the number.
A settlement should address accrued amounts, agreed exit payment, transition support and what claims are waived after payment.
The customer should also distinguish a negotiated commercial settlement from the legal enforceability of the original clause. A business may choose to pay an agreed amount to secure a quick exit even where it has arguments against the provider’s full demand. The settlement should make clear that the compromise resolves the identified claims rather than becoming an additional payment on top of them.
What We Usually Look At
We review the contract term, termination rights, cure period, performance evidence, future-fee wording, damages or penalty provisions, supplier cost evidence, avoided costs, governing law and the proposed settlement or release.
Common Traps
Typical mistakes are assuming all future fees are automatically payable, assuming the opposite and treating them as automatically unenforceable, mixing earned invoices with future services and paying a negotiated exit amount without obtaining a release.
Practical Next Step
Build an exit-cost bridge:
accrued services → committed costs → avoided costs → claimed loss → termination charge → settlement → release
That forces both sides to explain the number rather than argue only about the headline amount.
