Key Business Benefits

Switching to Sullivan White can save you money… Here’s how

We’ve crunched the numbers and have uncovered a sizeable money drain affecting many construction firms.  Here’s what we found.  With 70 subbies on the books an inhouse bookkeeper is likely spending around 3 days a week processing the wages.  If this reflects your sub-contractor workforce, processing CIS payments is costing your business around £300 a week in admin time.

The good news is that at Sullivan White we’ve got the process down to 1 day and 41 seconds.

That’s just £91.16 per week.

This slashes the cost of engaging a self-employed workforce.  Saving a contractor with a workforce of 70 subbies £805 a month – or £9,669,74p to be precise.

What would you do with an extra £9,669,74 in the budget?
