Chasing invoices shouldn't be this hard
Most UK SMEs lose hours every week to disorganised follow-up. Sound familiar?
Scattered emails
Reminders live across inboxes, spreadsheets, and sticky notes. There is no single source of truth for who was chased and when.
Missed follow-ups
Without a system, follow-ups happen late or not at all. Overdue invoices quietly age while you focus on delivery.
Broken promises
Customers say they will pay next week, but nobody tracks whether they actually do. Promises slip through the cracks.
No audit trail
When a dispute arises, you cannot prove what was sent, when, or what was agreed. It becomes your word against theirs.
Three steps to getting paid
From overdue invoice to payment — in a fraction of the time it takes manually.
Import your invoices
Upload a CSV or connect via API. Duesmith organises everything by customer, amount, and due date so you can see the full picture instantly.
AI drafts your reminders
Choose the tone — friendly, firm, formal, or final. Review every message before it goes out. Always human-approved, never fully automated.
Track everything in one place
Promises to pay, disputes, payments, and every action logged with timestamps. One workspace for your entire collections process.
