On Service document is a document type in SAP Business One that is used to record services that are not managed as warehouse items in item management. It is used to map purely service-related business transactions without a physical flow of goods.

Context and area of application:
The service document is used in sales and purchasing documents when services such as consulting, maintenance or support are to be recorded. Unlike article documents, service documents do not contain any material items. This document type is used in quotations, sales orders, deliveries, invoices and credit notes, among other things. It is particularly relevant for companies with service offers or service contracts, e.g. in the area of technical customer service, IT support or consulting.
Differentiation from related terms:
Service documents differ from Article vouchers because they do not reference stock items. It is not possible to mix items and services in a single document. To enable a combined display, services must alternatively be maintained as article master records. In addition, the document type must remain standardised when further processing documents (e.g. quotation → invoice).
Content features:
- Description instead of article number: The entry is made via a free text field for the service description.
- G/L account required: Each item must be assigned to a G/L account - either as a revenue or expense account.
- Pricing free: Prices are independent of the article master and can be assigned flexibly.
- Gross profit calculation: A gross profit percentage can be defined to analyse profitability.
Areas of application in the service module:
Service documents form the basis for the Service module in SAP Business One:
- Service calls: Document repairs or customer enquiries.
- Service contracts: Define conditions for services over a defined period of time.
- equipment master data: Manage serialised items with service reference.
- solution database: Records recurring problem solutions from service calls.
Exemplary use in business processes:
- Sale: Preparation of quotations, orders, invoices or credit notes for services (e.g. counselling hours).
- Purchasing: Recording of incoming invoices for services from external providers (e.g. IT services).
- Further processing: A service order can be transferred directly to an invoice without delivery, provided no physical goods are involved.
Example:
A consulting company creates a service order in SAP Business One for a one-day training course at the customer's premises. Instead of an article, a description such as „Onsite training SAP Business One, 8 hours“ is entered. Billing takes place via a previously defined revenue account. A delivery is not necessary, so an outgoing invoice can be created directly.
