As a measure to combat delinquency in commercial operations, it is stipulated in the third additional provision of Law 15/2010, of July 5, that all commercial companies must expressly include in the annual accounts report their period means of payment to suppliers, understood as the period that elapses from the delivery of the goods or the rendering of the services and the material payment of the operation.

For this purpose, to determine the way to calculate this ratio we must address the Resolution of January 29, 2016, of the Institute of Accounting and Auditing of Accounts, on the information to be included in the annual accounts in relation to the period means of payment to suppliers in commercial operations, distinguishing in their operation between the mercantile companies that elaborate the normal model of the report and those others that on the contrary formulate the abbreviated model or apply the General Accounting Plan for Small and Medium Enterprises.

How To Calculate The Average Period of Payment to Suppliers

As expected, the mercantile companies that prepare the report in the abbreviated form of the General Accounting Plan or that apply the General Accounting Plan for Small and Medium Enterprises will calculate the average period of payment to suppliers in a simplified manner through the following formula:

In this sense, we must take into account that commercial creditors include the items of suppliers and various creditors for debts with suppliers of goods or services included in subgroups 40 and 41 proposed in the chart of accounts of the General Accounting Plan.

On the other hand, net purchases and expenses for external services include the amounts accounted as such in subgroups 60 and 62 of the PGC, that is, without including taxes.

Once the average period of payment to suppliers has been calculated, this information should be expressed through the following table, which for the annual accounts for 2016 is placed on the new IDP2 page of “General identification data and additional information required, together with the information on the application of the results:


On the other hand, for the mercantile companies that elaborate the normal model of memory the calculation of the average period of payment to suppliers.also you can compare these prices with different merchant accounts and you can pick one for your business. For these purposes, the number of days pending payment will be considered as the total number of calendar days that have elapsed since the date of receipt of the goods or provision of services until the last day of the period to which the annual accounts refer. However, when there is no reliable information, the date of receipt of the invoice may be taken as the beginning of the term.

Finally, it is worth remembering that in accordance with the regulations on late payments, the maximum payment period that can be agreed is 60 calendar days, so that in case the average payment period calculated according to the above formulas is higher At said maximum, the measures to be applied in the following fiscal year for its reduction shall be indicated
