In practice, it is not uncommon for the effective date of a contract to differ from its signing date. For example, a contract may have an effective date in October, but the actual signing date is in December. In such cases, should the starting point for revenue recognition be based on the effective date (October) or the signing date (December)? This issue requires careful handling, especially when the enterprise has not yet adopted the new revenue standard.

First, it is necessary to clarify the legal meanings of "effective date" and "signing date." The effective date of a contract generally refers to the date on which the contract terms begin to bind both parties, while the signing date is the date on which both parties complete the signing and sealing. If the contract explicitly stipulates that the effective date is earlier than the signing date, the effective date may have retroactive effect, but this does not automatically determine the accounting timing for revenue recognition.

Under the current revenue recognition framework (i.e., the old standard), the core principle for revenue recognition is "realized or realizable and earned." This means that the prerequisite for recognizing revenue is that the enterprise has fulfilled its corresponding performance obligations and it is probable that economic benefits will flow to the enterprise. Therefore, the effective date of the contract alone is insufficient to determine when revenue should be recognized; it is also necessary to assess whether, during the period from October to December, the enterprise actually provided services or delivered goods, and whether the customer obtained and accepted the related economic benefits.

If the contract becomes effective in October, but the enterprise does not complete the signing until December, and the actual performance activities (such as delivery or service provision) also occur in December or later, then revenue recognition should generally begin when the performance obligation is fulfilled, which may be in December or later. Conversely, if the enterprise began performance after the contract became effective in October and the customer obtained control, then even if the signing date is delayed, revenue recognition may still be traced back to October, provided that all recognition conditions are met.

In addition, attention should be paid to whether the contract contains a "retroactive effectiveness" clause. If the contract explicitly stipulates that it takes effect from October 1 and both parties acknowledge this retroactive effect, then accounting may need to use October as the starting point for revenue recognition, but only if the related revenue met the recognition criteria in October. If such a clause is absent, or if actual performance does not match the effective date, the actual date of performance completion should prevail.

It is worth noting that when the new revenue standard (such as IFRS 15 or ASC 606) has not been adopted, the enterprise still follows the old standard (such as IAS 18 or ASC 605). The old standard places greater emphasis on the transfer of risks and rewards rather than the transfer of control. Therefore, determining the timing of revenue recognition requires a focused analysis of whether, during the period from October to December, the risks and rewards of the goods or services have been transferred to the customer, and whether the enterprise retains continuing managerial involvement or effective control.

In summary, for a situation where the contract effective date is in October and the signing date is in December, the starting month for revenue recognition cannot be generalized. The enterprise should make a comprehensive judgment based on the specific terms of the contract, the actual progress of performance, the timing of the transfer of risks and rewards, and relevant evidence (such as delivery records and acceptance certificates). If the revenue recognition conditions are met in October, revenue should be recognized from October; otherwise, it should be deferred to the month when the conditions are actually met (such as December). It is recommended that financial personnel collaborate with the legal department to review the effectiveness clauses and performance obligations in the contract, and consult professional audit opinions when necessary.

Finally, if the enterprise plans to adopt the new revenue standard in the future, it should be noted that the new standard has a stricter definition of the timing of "contract inception," which may affect the handling of similar situations. However, under the premise that the new standard has not yet been adopted, the above analysis remains applicable.
