fertigzustellen

Fertigstellen is a German verb meaning to complete or finalize something, bringing a task, product, project, or document to a finished state. It is used for items that require a final step or finishing touches before they are considered ready for use or delivery. The construction is typical for formal, technical, and everyday contexts, such as manufacturing, construction, software development, and editing.

Grammatically, fertigstellen is a compound verb formed from fertig (ready) and stellen (to place/put). In main clauses the prefix is separable: Ich stelle das Produkt fertig. In subordinate clauses and in the infinitive, the form remains zusammen: fertigzustellen. The perfect tense uses the participle fertiggestellt with haben: Ich habe das Produkt fertiggestellt. The related noun is die Fertigstellung, referring to the act of finishing or the state of being completed, and terms like der Fertigstellungsgrad (degree of completion) are common in project management.

Usage and nuance include synonyms such as abschließen, vollenden, beenden, and the calque finalisieren (often seen in business language). Fertigstellen emphasizes bringing something to a state of readiness rather than merely starting or continuing work. It is widely used across industries to describe the last steps that convert work in progress into a finished, deliverable result.

Example: Der Bauplan wurde erfolgreich fertiggestellt, und das Projekt geht in die nächste Phase über. In software: Wir müssen noch einige Features fertigstellen, bevor die Veröffentlichung erfolgt.
