Ontario fire-protection and appliance service firm OFS Group uses Abivo's AI voice agent "Kate" to phone customers about overdue invoices, capture promises to pay and log summaries, recovering $842,518 in four months

L3 · Conditional Verified · Production Facilities Services Accounting/Finance

OFS Group (founded 1966, 50-100 staff) had aging receivables after growth and a systems transition. Abivo's voice agent Kate calls customers about outstanding invoices using balance, due-date and history data, holds payment conversations, clarifies disputes and timing objections, and captures promises to pay and follow-up needs, syncing a summary to Abivo's dashboard for the OFS team. Abivo reports $842,518 in overdue payments recovered within four months of go-live, DSO down by more than 30 days, and the collections team going from four callers to one (reported by Abivo, quoting OFS Group's CEO and Financial Controller; vendor-published)

Problem

Multiple service types, contract structures and payment terms left more balances aging than leadership wanted, and chasing was manual (reported by Abivo)

Workflow

  1. Agent pulls current balance, due date and payment history for overdue invoices
  2. Agent calls the customer and holds a payment conversation
  3. Agent clarifies disputes and handles timing objections
  4. Agent captures promises to pay, preferred dates and follow-up needs
  5. Summary syncs to the dashboard; OFS staff review and handle open issues

Human-in-the-loop: OFS staff review call summaries and handle open customer issues and disputes; one human caller remains.
