to step in
To take over another person's tasks or role at short notice when they are unexpectedly unavailable. You help out by filling in for someone.

'Einspringen' is a separable verb. The prefix 'ein-' goes to the end in a main clause. In subordinate clauses and in the infinitive with 'zu', the verb stays together.
Ein Kollege springt morgen für mich ein.
A colleague is stepping in for me tomorrow.
The perfect tense of 'einspringen' (to step in) is always formed with the auxiliary verb 'sein'. This is because of the idea of movement into a new position or task.
Gestern ist spontan eine andere Pianistin für den kranken Solisten eingesprungen.
Yesterday, another pianist spontaneously stepped in for the sick soloist.
When you step in for a person, you always use the preposition 'für' followed by the accusative. You step in 'für jemanden' (for someone).
Kannst du am Freitag für mich einspringen? Ich habe einen wichtigen Termin.
Can you step in for me on Friday? I have an important appointment.

to represent
'vertreten' and 'einspringen' can both mean taking over another person's task. 'vertreten' is more general and can be planned or official, for example during vacation, illness, or in a particular role. 'einspringen' sounds more last-minute: someone is unexpectedly absent, and another person quickly helps out. The words can be confused because when you 'einspringen', you often 'vertreten' someone. As a rule of thumb: someone who 'einspringt' usually stands in for someone, but not every case of standing in is a last-minute 'Einspringen'.
