A great analysis that shows starkly the challenge many SME’s face when dealing with unpaid invoices, trying to find the answer between not wanting to upset client/customer relationships but needing the cashflow and finding a cost and time efficient way of dealing with it. At Ascent we have a great tool for all SME’s - www.debtguard.co.uk our online only self serve tool where you can send a solicitors letter for just £2.00 that you’ll find works more often than not. In terms of when is the right time to use it  - we’d recommend escalating an unpaid invoice between day 45 and day 60 past the invoice due date.
