Compliant payments for independent contractors

Our payment solutions service guarantees that companies correctly classify freelancers and independent contractors, ensuring payments are simple, compliant, and less costly.

If your workforce is made up of freelancers and independent contractors, you may be open to the risk of an HMRC investigation and may find that the cost of processing payments for your workforce is spiralling.

It can take an in-house bookkeeper an average of 3 days to process payments for a team of 70 contractors. That’s why our team ensures you never need an in-house resource to do this task again.

Key Business Benefits

Switching to a CIS payment service 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?
