It is not a problem if you have raised funds elsewhere. Our Fundraising Hub's have the ability to include offline donations. If your business has already directly donated to the charity these figures can be included to the page so it always reflects the total you have raised.
We also have the ability to link activity from JustGiving! If your company has old or active pages on JustGiving which you would like included in your Hub we can easily link the pages for you.
