For over 150,000 UK sole traders, contractors, tradespeople, and digital freelancers, FreeAgent is the premier cloud accounting and Making Tax Digital (MTD) platform—especially popular among NatWest, Royal Bank of Scotland, and Mettle business banking customers. FreeAgent simplifies expense logging, self-assessment tax calculations, and VAT returns. Yet despite generating polished, HMRC-compliant invoices, micro-business owners routinely battle an exhausting cash flow bottleneck: overdue invoices and unpaid bills averaging 32 to 48 debtor days.
Chasing unpaid invoices via traditional email reminders produces rapidly diminishing returns. Automated invoice emails sent from standard accounting mailboxes get trapped in junk folders, buried under promotional newsletters, or simply deferred by busy clients who find logging into online banking too tedious on their smartphones. When business owners resort to manual phone calls, they spend hours playing voicemail tag or having uncomfortable financial conversations while on job sites.
The modern solution is connecting FreeAgent directly to Susan AI on WhatsApp. By delivering polite, personalized invoice summaries and 1-tap Apple Pay, Google Pay, or card payment links directly into the customer's WhatsApp inbox, businesses reduce overdue debtor days by over 65% and get paid three times faster without awkward manual chasing.
