Sterling provide flexible, high quality outsourced credit control, finance back office, and debt recovery services to clients in the UK and US. Our customers range in size from SME’s with £1m turnover up to $800m turnover multi-nationals. We cover all business to business sectors and are particularly strong in the recruitment and accountancy sectors.

Some clients use us to collect problem debts as and when required on a no-win, no-fee basis. For others we effectively become our client’s credit control of finance back office function, working entirely under the client brand so that the outsource is invisible to their customers. Our finance back office covers accounts payable, expenses, bank reconciliation, bookkeeping, and management accounts.

We work as an extension to our client’s business, tailoring our service to dovetail into their business processes and infrastructure. Our experienced collection staff work closely with your customers to get your invoices paid quickly whilst protecting and improving your customer relations. Whilst our clients put differing emphasis on objectives when outsourcing to us the majority wish to improve cash flow. Sterling have reduced debtor days by a minimum of 20% for all of our clients, with the average improvement being 30%, and some clients seeing a 65% improvement.
