    Click to play

    Your overseas client hasn't paid. The invoice is 60 days overdue. You've sent polite reminders that disappeared into the void. Time zones make calls impossible. You're not even sure which country's laws apply.

    This playbook gives you a structured, compliant method to recover international B2B debts in 30–90 days—without damaging the relationship or violating local regulations. Note: Actual timelines vary by jurisdiction, debtor behavior, and complexity of the case.

    We call this method The Cross-Border Collections Ladder™—a six-step escalation framework designed for international commercial debt recovery.

    Why overseas invoices go unpaid (and why reminders fail)

    Internal bureaucracy

    Your invoice lost in their AP queue, waiting for approvals

    Intentional delay tactics

    Cases with partial payment history + clean documentation resolve 3× faster on average.

    The Cross-Border Collections Ladder™ (the step-by-step method)

    1

    Before any collection activity, verify your documentation is bulletproof: Why it matters: Debtors in dispute mode will challenge every detail. Incomplete documentation is the #1 reason international collections fail.

    • ✅ Original purchase order or signed contract
    • ✅ Proof of delivery (shipping documents, delivery receipt, digital confirmation)
    • ✅ Acceptance evidence (email acknowledgment, signed delivery note, usage logs)
    • ✅ Complete invoice with correct entity name, amount, currency, and payment terms
    • ✅ All correspondence regarding the transaction
