Wer an wen in welchem Kontext?

Du zu einem Kunden, einem Kollegen, einem Fremden auf der Straße?

This is clearly a past tense (konnte). Depending on exact context:

I hope I was able to help (you)

or (more likely)

I hope I've been able to help (you).

or

I hope I've been of some help.

zu einem Kollegen

Then escoville.

If it was a client, you would perhaps prefer "I hope I was able to be of assistance".

"weiterhelfen" (statt nur "helfen") stellt die Sachinformation, die gegeben wurde, in den Mittelpunkt. Deswegen erscheint mir

I hope this is helpful for you
I hope this helps

treffender.
