Reference metadata describe statistical concepts and methodologies used for the collection and generation of data. They provide information on data quality and, since they are strongly content-oriented, assist users in interpreting the data. Reference metadata, unlike structural metadata, can be decoupled from the data.
The purpose of calculating service producer price indices (SPPIs) is to measure the overall service producer price change during a certain period.
SPPIs are necessary for calculating macroeconomical indicators at constant prices, analising inflation processes in the services sector, preparing forecasts.
3.2. Classification system
NACE Rev.2 (Statistical Classification of Economic Activities in the European Community).
CPA 2.1 (Statistical Classification of Products by Activity in the European Economic Community).
3.3. Coverage - sector
SPPI are compiled according to Regulation (EU) 2019/2152 of the European Parliament and of the Council of 27 November 2019 on European business statistics, repealing 10 legal acts in the field of business statistics.
Commission Implementing Regulation (EU) 2020/1197 of 30 July 2020 laying down technical specifications and arrangements pursuant to Regulation (EU) 2019/2152 of the European Parliament and of the Council on European business statistics repealing 10 legal acts in the field of business statistics.
The indicators cover economic activities listed in the following sections of NACE Rev. 2:
H – transportation and storage
I – accomodation and food service activities
J – information and communication
L – real estate activities
M – professional, scientific and technical activities
N – administrative and support service activities.
The SSPI are output price indices for the production of services from domestic producers and show the evolution of prices for the services that are provided to customers which are enterprises, they refer to services that are used as intermediate use (Business to Business-Β2Β).
Price index is a relative indicator that shows the change in prices over a certain period of time.
The base period of an index is the base period for which the index is equal to 100. Having a time series of price indices calculated with a single base period, it is possible to determine the ECI for different periods.
Price base period – the base period against which the overall price change is measured.
Weight base period – the base period based on the data of which the index weights are calculated.
Weight – the volume of goods at a given classification level in value terms compared to the volume of goods at a higher level in value terms in the base period. The higher the weight, the greater the impact of a change in the prices of goods at a given classification level on the change in the prices of goods at a higher level.
Contract pricing: Actual selling price in long term contracts for repeated delivery, to the same customer.
Direct use of prices of repeated services: Actual selling price of relatively uniform services, sold regularly to different customers.
Hourly rate: Hourly list prices for various categories of staff or services, depending on expertise, level of education or seniority.
Model price: A hypothetical or historically sold service. The price is recalculated every quarter by adjusting the factors in the price calculation.
Percentage fee: Actual price of services, as a percentage of a contract, an asset or other products.
Realized hourly rate: Actual hourly prices are calculated by dividing quarterly revenue for a given service, by the number of hours an employee has spent on this during that quarter.
Unit value: Actual selling price is calculated by dividing quarterly revenue for a given service, by number of units sold.

More information on assurance of quality of statistical information and its preparation is published in the Quality Management section on the Statistics Lithuania website.
11.2. Quality management - assessment
Data quality corresponds to accuracy, timeliness and punctuality, comparability and compatibility requirements. Statistical survey managers periodically perform self-assessment – to evaluate statistical survey processes; moreover, statistical questionnaire control testing is performed.
12.1. Relevance - User Needs
The main users of statistical information are the European Commission institutions, the European Central Bank, the Bank of Lithuania, state and municipal institutions, international organisations, the media, business, research communities and academic representatives, students and other users, whose needs are met without violating the principle of confidentiality. The CPI is used as deflators for the compilation of national accounts and services statistics.
12.2. Relevance - User Satisfaction
Since 2005, user opinion surveys have been conducted on a regular basis. Official Statistics Portal traffic is monitored, website visitor opinion polls, general opinion poll on the products and services of State Data Agency (Statistics Lithuania), target user group opinion polls and other surveys are conducted. In 2007, the compilation of a user satisfaction index was launched. The said surveys are aimed at the assessment of the overall demand for and necessity of statistical information in general and specific statistical indicators in particular.
The general system for the measurement and monitoring of performance quality is in place at State Data Agency (Statistics Lithuania).
The following tools for SPPI quality monitoring and assurance are used:
Self-assessment of survey managers (based on DESAP (European checklists for survey managers)
Testing of previously approved statistical questionnaires.
Statistical presentation: A purposive sampling method is used for the selection of legal units, service groups and representative services. Statistical data on legal units providing services for the previous years are used to ensure that the income of legal units selected for the statistical survey makes up not less than 90 per cent of total income of legal units within the respective economic activity. The income of the legal units questioned in the survey should make up no less than 70–80 per cent of the total income of all the legal units within the respective economic activity.
Accuracy: The SPPI time series are calculated based on the 2010 index reference period accurate to ten decimal places. The results are rounded to four decimal places and then published in the Database of Indicators (on the Official Statistics Portal) and provided to Eurostat. Monthly, annual, average annual and other price changes are calculated using the SPPI time series accurate to all decimal places and are published rounded to one decimal place.
Impact of sampling errors: Sampling errors are not systematically measured. Sampling errors are not relevant in the scope of the SPPIs. To reach a better response rate in every quarter a missing price in the reference period is estimated using the previous period's data on enterprises or the average price development for similar products/enterprises.
Impact of non-sampling errors: For the SPPIs non-sampling errors are not quantified but are considered to be small.
Accuracy of the first estimates: No first estimates are made. The results published are final and not revised later. Representativity:
A purposive sampling method is applied to the selection of legal units, service groups and representative services. Statistical data on the annual income of legal units providing services for the previous years are used in order that the income of the legal units selected for a statistical survey on service prices would make up not less than 90 per cent of total income of legal units in the respective economic activity. After the legal units sampled have been questioned, the income of the legal units which have responded should make up not less than 70–80 per cent of the total income in the respective economic activity.
Accuracy: SPPI time series are calculated based on the 2010 index reference period and are accurate to ten decimal places. The results are rounded to four decimal places and published in the Database of Indicators (on the Official Statistics Portal) and provided for Eurostat. Quarterly, annual, average annual and other price changes are calculated using SPPI time series accurate to all decimal places and published rounded to one decimal place.
13.2. Sampling error
Role of sampling: Sampling errors are not calculated for SPPIs because the sample is not based on random sampling. The list of enterprises engaged in price monitoring is reviewed every year.
Multiple use of sampling in production: Not applicable.
Coverage of the main aggregates: Not applicable.
Numeric information: Not applicable.
Non-probability and cut-off sampling: Not applicable.
Clarity: Not applicable.
Non-probability and cut-off sampling: Not applicable.
13.3. Non-sampling error
In 2024, the SPPI had a 100 % response rate.
In order to minimise the impact of errors in the data provided by respondents on SPPI indices, appropriate validation procedures are applied. In case of non-response, missing values are imputed. Estimates are made depending on the sector they belong to. In most cases, the price is estimated using the average change in the rest of prices collected for the same service or the corresponding branch. In order to increase the response rate, telephone and e-mail follow-ups take place.
Coverage errors: Not applicable.
Data collection or access errors: The impact of data collection (survey instrument, respondent) on the main estimates is not estimated.

15.3. Coherence - cross domain
Lithuanian SPPI’s are compared with European SPPI time series.
15.4. Coherence - internal
SPPIs are internally coherent. Lower-level price indices are aggregated to higher-level price indices according to the Laspeyres' formula, using base weights. Each higher-level price index is calculated as a weighted arithmetic mean of lower-level price indices.
In 2024, 105.0 thousand euros were allocated for the statistical study of the price index of services provided to economic entities.
2005 service-providing companies were selected for the 2024 statistical survey.
The average time spent by respondents on the filling-in of the statistical questionnaire KA-03 (annual) is 57 min., KA-04 (quarterly) – 31 min.
In 2024, the costs of the NSI were 5 929 hours per year, burden on respondents was about 3 hrs 1 min. per year. Compared to the previous year, the statistical reporting burden has remained unchanged.
Statistics Lithuania pays great attention to reducing the statistical reporting burden on respondents. Its obligations to implement the Law of the Republic of Lithuania on Reducing the Administrative Burden and to reduce the statistical reporting burden on respondents are defined in the Policy on Reducing the Statistical Reporting Burden on Respondents.
After amendments in legal acts, detection of significant errors, revisions of statistical indicators are performed. Users are informed about their results and changes immediately. Users are informed about planned revisions in advance through a planned statistical information revision calendar.
The results published are final and not revised later.
18.1. Source data
The main data source is the statistical service producer price survey.
The data used to calculate the SPPI are mainly obtained through this statistical survey, covering enterprises providing services to other businesses and employing 5 and more persons.
The survey sample is drawn using a purposive sampling method. The selection of enterprises for the survey is performed by the Price Statistic Division. An essential criterion for selection is annual income from services. For each activity, the selection of units is carried out to cover from 70 to 80 per cent of income within this activity.
The survey covers about 2 005 enterprises.
The sample of reporting units is updated at the end of every year.
The sample of products is updated at the end of every year and is verified quarterly, depending on needs.
In 2024, on average, approx. 2 673 prices of products were collected in approx. 1 926 enterprises on a quarterly basis.
For collecting weights, an annual questionnaire KA-03, for collecting prices – a quarterly questionnaire KA-04 are used.
18.2. Frequency of data collection
Prices are collected quarterly.
18.3. Data collection
Statistical data are collected in the electronic statistical data preparation and transmission systeme. Statistics (only in Lithuanian).
Statistical questionnaire (only in Lithuanian) – annual questionnaire for the selection of representative services (code KA-03) and quarterly questionnaire on service producer prices (code KA-04) are used for collecting data on prices.
Statistical data are presented in the annual Statistical Report on the Selection of Representative Services Provided KA-03, approved by Order No. DĮ-301 of the Director General of Statistics Lithuania of 20 December 2023, and in the quarterly Statistical Report on the Prices of Services Provided to Economic Entities KA-04, approved by Order No. DĮ-65 of the Director General of Statistics Lithuania of 13 March 2024.
Statistical reporting forms are regularly reviewed and, if necessary, improved (last tested in 2017) in order to reduce the statistical reporting burden on respondents.
Statistical report forms are published at the following address: Statistical reporting forms (only in Lithuanian).
18.4. Data validation
To ensure the quality of statistical data, statistical data analysis, data verification and validation, editing and recording of missing values at the level of statistical data arrays are performed. For various reasons, there are cases when a company cannot provide prices. In such a case, the price of the previous quarter may be repeated or estimated. The completeness and reliability of the entered statistical data are checked, the data are compared with data from the previous period, with additional data sources. If questions arise, respondents are contacted, and statistical data are corrected.
A specialist of a regional Data Preparation Division carries out the primary verification of the data received.
The Price Statistics Division carries out the secondary verification and editing as well as validation of the data using a data control program designed for checking statistical price data.
Data are compared to the data for the previous periods. Reasons for changes (when changes are ≥ +10 per cent or ≤ –10 per cent) in prices are analysed.
Particular attention is paid to quality changes, to prices that do not change for a very long time, to the lowest and the highest prices.
Price trends are also checked against those in producer prices.
18.5. Data compilation
The SPPI is a Laspeyres-type price index. The lowest-level price indices are the ratios of the individual prices of individual representative services in the reference quarter to the prices in IV quarter of the previous year. Individual service price indices are aggregated using weights for the reference period (turnover for weights collected specially from respondents) – to obtain higher‑level indices for service headings (CPA 6- and 5-digit levels) for each respondent. Then, the weights collected from respondents are used to obtain higher-level indices (NACE Rev. 2 4‑digit level) for each respondent. These indices are aggregated to the price indices for each activity at NACE Rev. 2 4-, 3- or 2-digit level using weights for the reference year from transport and services statistics.
Qualitative changes are taken into account through the use of an overlap method (prices for old and new services are collected in the same month, and the difference between the two prices is taken as a measure of their quality difference) or an expert estimation method, which is based on information on the percentage price effect of quality difference provided by respondents. In case of a missing price, the previously observed price is carried forward or the missing price is imputed by observing the movement in prices for similar services or a group to which the service belongs. If a service becomes permanently unavailable, an appropriate replacement service is selected with specifications close to the previous variety. In case of liquidation of the enterprise or when no appropriate replacement service can be found, figures for services are imputed until the end of the year, after which the service is abandoned. New representative services and new enterprises are introduced at the beginning of each year.
Quality changes are taken into account through the use of a bridged overlap and expert estimation methods.
Statistical data are adjusted if the quality of the new (replacing) representative service considerably differs from that of the former (replaced) one; in such case, the impact of the change in quality on the price change is estimated.
To maintain compatibility between the price of the replacing and the replaced product, service quality has to be adjusted: the price of the replaced product in the base period is adjusted by eliminating the impact of the change in quality. Methods applied: bridged overlap; overlap; expert estimation.
Small changes in characteristics, which are not believed to influence the price, are ignored, and prices for the old item and its replacement are compared directly. Price indices are neither seasonally nor calendar adjusted. When prices for seasonal items are temporarily absent, the last observed price is carried forward.

The lowest-level price indices are the ratios of the individual prices of individual representative services in the reference quarter to the prices in IV quarter of the previous year. Individual service price indices are aggregated using weights for the reference period (turnover for weights collected specially from respondents) – to obtain higher‑level indices for service headings (CPA 6- and 5-digit levels) for each respondent. Then, the weights collected from respondents are used to obtain higher-level indices (NACE Rev. 2 4‑digit level) for each respondent. These indices are aggregated to the price indices for each activity at NACE Rev. 2 4-, 3- or 2-digit level using weights for the reference year from transport and services statistics.
Qualitative changes are taken into account through the use of an overlap method (prices for old and new services are collected in the same month, and the difference between the two prices is taken as a measure of their quality difference) or an expert estimation method, which is based on information on the percentage price effect of quality difference provided by respondents. In case of a missing price, the previously observed price is carried forward or the missing price is imputed by observing the movement in prices for similar services or a group to which the service belongs. If a service becomes permanently unavailable, an appropriate replacement service is selected with specifications close to the previous variety. In case of liquidation of the enterprise or when no appropriate replacement service can be found, figures for services are imputed until the end of the year, after which the service is abandoned. New representative services and new enterprises are introduced at the beginning of each year.
The main data source is the statistical service producer price survey.
The data used to calculate the SPPI are mainly obtained through this statistical survey, covering enterprises providing services to other businesses and employing 5 and more persons.
The survey sample is drawn using a purposive sampling method. The selection of enterprises for the survey is performed by the Price Statistic Division. An essential criterion for selection is annual income from services. For each activity, the selection of units is carried out to cover from 70 to 80 per cent of income within this activity.
The survey covers about 2 005 enterprises.
The sample of reporting units is updated at the end of every year.
The sample of products is updated at the end of every year and is verified quarterly, depending on needs.
In 2024, on average, approx. 2 673 prices of products were collected in approx. 1 926 enterprises on a quarterly basis.
For collecting weights, an annual questionnaire KA-03, for collecting prices – a quarterly questionnaire KA-04 are used.
Quarterly.
SPPIs are released each quarter, at 09:00 a. m. (local time), on the 75th day after the end of the reference quarter.
