When a customer is 100 days past due and goes silent, you are no longer managing payment timing or liquidity. You are managing customer behavior and running loss mitigation. The communication breakdown indicates something more serious than temporary cash-flow issues. This playbook addresses how to handle the silent, deeply delinquent account.

The Reality of the 100-Day Stalemate

When an account crosses the 100-day threshold without a clear payment plan, the dynamic changes. Several patterns emerge repeatedly.

The Threat-Only Responder

Credit teams report customers who have the money but treat trade credit as a 0% interest loan until forced to pay. They rely on the credit team's politeness to delay payment. These customers ignore calls and emails until threatened with collections and legal action. Average collection periods exceed 107 days (more than three months past standard terms). The resolution requires threatening legal action, which damages the commercial relationship but prompts a response. Many of these customers are ultimately reverted to COD terms.

The Leverage Imbalance

Sometimes, the amount past due is small, but the risk of future exposure is high. A credit manager might be holding a small past-due balance while the sales team is trying to push through a massive new order. This creates a dangerous leverage point.

Credit teams describe scenarios like struggling to collect $2,000 while $60,000 in open orders await shipment. If a customer struggles to pay $2,000 or refuses to pay, allowing $60,000 in new exposure creates fundamental risk. The silence (lack of communication) combined with 116-day average payment cycles, forces total credit revocation.

The Small Balance Drain

Small balances that sit on the ledger for months require just as much administrative work as large ones. If a customer refuses to clear a small limit, it signals a deeper administrative disregard for your terms.

Teams report giving customers multiple opportunities to pay small credit limits within reasonable timeframes, only to have them fail repeatedly. Small balances eventually get paid 120 days late, prompting account closure. The cost of collecting the money eventually exceeds the profit margin on the customer's business.

The Total Ghost

In the worst-case scenario, the customer stops engaging entirely. This forces the credit team to outsource the problem, accepting that they will likely lose a percentage of the debt to collection agency fees.

Credit teams report DSO reaching 166 days (nearly six months old) when customers do not respond, forcing transfers to collections to recover the money. The likelihood of full recovery declines significantly over time, making the lack of a response the critical factor in sending the file to external collections.

Root Cause Analysis: Why Do They Go Silent?

Why does a B2B customer, who likely needs your product or service, stop communicating after 90 or 100 days? The operational reality is often more nuanced than simple cash flow issues.

The Squeaky Wheel Prioritization

Many accounts payable departments are instructed to prioritize vendors who stop service. If your company continues to ship goods or provide services despite the past-due balance, you signal that payment carries no urgency. The customer's AP team will allocate their limited cash to vendors who have put them on credit hold. Polite vendors who keep shipping get paid last.

ERP Visibility Gaps

In many organizations, the sales team cannot see the granular details of the aging report. They see a Credit Status: Active flag and continue to book orders. The customer sees this as confirmation that their delay is acceptable. The disconnect between the credit department's concern and the sales department's behavior confuses the customer's AP team or gives them a false sense of security.

The Dispute Stall

Sometimes, silence is a tactic to mask a dispute that was never formally filed. A customer may ignore invoices for 100 days, and only when threatened with legal action do they claim the pricing was wrong. This converts a credit issue into a dispute-resolution issue, giving them even more time while the credit team investigates.

Liquidity Triage

When a company is in genuine distress, it often cuts off communication with vendors to avoid admitting insolvency. Silence at 120 days is a strong leading indicator of potential bankruptcy. They are likely paying critical utilities and payroll while ignoring trade creditors until the last possible moment.

The 100-Day Escalation Protocol

Waiting 100 days for a customer to reply rarely succeeds. Credit teams need a definitive escalation playbook that removes emotion and relies on pre-set triggers. This ensures that decisions like revoking credit or filing legal claims are business processes, not personal conflicts.

Phase 1: The Pattern Interruption (Days 90-100)

If standard email reminders are being ignored, the communication channel must change. The goal here is to determine if the customer is insolvent or just ignoring you.

  • The Medium Shift: Stop emailing. Pick up the phone. If they do not answer, call a different department (e.g., sales or operations) and ask to be transferred to finance. This bypasses caller ID screening.
  • Optimize Your Messages: Before escalating to legal threats, use Dunning Doctor to rewrite your collection emails. The tool rewrites dunning messages using language proven to get 3X higher response rates. At 90+ days, the difference between a generic Past Due notice and a psychologically optimized message can mean the difference between a response and continued silence.
  • The Sales Loop-In: Inform your internal sales rep that the account is moving to Pre-Collection status. Often, the sales rep has a mobile number or another contact who can respond.
  • The Hard Hold: Ensure the ERP system is set to a hard stop. No new orders, regardless of size, can be released. This is critical for the Squeaky Wheel dynamic.

Phase 2: The Leverage Pivot (Days 101-110)

This phase addresses the scenario where the customer owes a small amount but wants a large order.

  • Leverage Open Orders: If the customer has $60k in open orders and owes $2k, do not ship a single unit. Use the urgency of the new order to force payment of the old debt.
  • Refuse Partial Solutions: A common stall tactic is to pay the oldest invoice only. At 100+ days, the credit manager should require the account to be brought current, or at least significantly paid down, before releasing new goods. Accepting a token payment resets the clock but does not solve the behavior.

Phase 3: The Ultimatum (Days 111-120)

If silence continues, the relationship has effectively ended. The focus becomes recovery.

  • The Final Demand Letter: Send a formal letter (physical and digital) stating a specific date (e.g., 7 days) by which the file will be turned over to third-party collections or legal counsel. Use Dunning Doctor to optimize the language in this final communication for maximum impact before escalating to legal action.
  • Revocation of Terms: Permanently revoke credit terms. Even if they pay now, the trust is broken. Move them to Cash in Advance (CIA) or Credit Card only. Reverting to COD is a protective measure for the future, not a punishment.

Phase 4: Execution (Days 121+)

  • Third-Party Handoff: If the deadline passes, execute the threat immediately. Sending the account to collections at day 166 is often too late. The faster the file moves to professional collections, the higher the recovery rate.
  • Write-Off and Close: For small balances where legal fees would exceed the debt, close the account and write it off. Do not leave it open to tempt future sales.

Impact of Decisive Action

Implementing a strict 100-day playbook impacts more than just the bad debt reserve. It signals to the market and your internal teams that payment terms are requirements, not suggestions.

Operational Efficiency

Chasing a silent customer for 160 days wastes hours of credit analyst time that could be spent on onboarding good customers or managing complex, high-value accounts. Closing the loop at 120 days frees up capacity.

Risk Mitigation

Allowing a customer to float 116 days on a small balance creates a blind spot. If they suddenly place a large order and the system auto-approves it based on an Active status, the exposure jumps exponentially. Revoking credit prevents this shock.

Cash Flow Predictability

Removing the wild card accounts from the forecast allows treasury to plan better. Knowing that an account will either pay or be written off by day 120 provides certainty, whereas an account dragging to day 166 creates a perpetual gray area in cash forecasting.

Conclusion: The Checklist

When you see an account hit the 100-day mark with no response, run through this checklist before the end of the week:

  1. Stop the Bleeding: Is the account on strict credit hold in the ERP? Are we 100% sure no automated shipments can leave the dock?
  2. Verify the Contact: Have we called a non-AP contact (e.g., the buyer or site manager) to verify the company is still operating?
  3. Check the Leverage: Do we have pending orders we can use as a bargaining chip?
  4. Set the Deadline: Have we sent a final notice with a specific drop-dead date for legal/collections transfer?
  5. Plan the Offboarding: Have we prepared the paperwork to switch this customer to COD/CIA permanently once the debt is settled?

Proactive escalation is the only way to break the silence. Waiting for a silent customer to volunteer payment often leads to 166-day delays.

Customers ignoring calls and emails past 100 days? Small $2K balance but $60K in open orders? Bectran's collections platform includes automated escalation workflows triggered at 90/100/120-day thresholds, credit hold enforcement that prevents shipments to deeply delinquent accounts regardless of Active status, leverage tracking (open orders + pending shipments) to identify negotiation opportunities, Dunning Doctor to optimize collection messages for 3X higher response rates before legal escalation, and collections handoff workflows that automate transfer to third-party agencies at predefined deadlines—ensuring consistent enforcement and preventing 166-day collection cycles.
