When to escalate from in-house chasing to third-party collections Part 2 : the decision checklist

Part one explained why timely escalation matters and the signals to watch. Part two gives you a structured decision checklist you can apply case by case.
The decision checklist
Work through these questions. If you answer “no” or “red” at any stage, fix the gap; if you answer “yes” or “green” across the board and you’re still unpaid, escalate.
1) Is the debt valid, clear and documented?
-
Contract/SOW and PO: do you have signed terms, a valid PO (if required) and an exact scope?
-
Delivery/acceptance: can you evidence delivery, timesheets, completion or UAT sign-off?
-
Invoice hygiene: correct legal entity, VAT treatment, PO, line detail and dates?
-
Dispute status: is any dispute specific and evidenced, or vague and shifting?
Decision: if paperwork is incomplete or a genuine defect exists, remedy first. If documents are complete and any dispute is unsupported, proceed.
2) Have you completed a fair in-house cycle?
Minimum best practice for UK credit control:
-
T-0: invoice issued with clear “pay by” date, payment options and queries contact.
-
T+7 days past due: friendly reminder by email.
-
T+14: call to accounts payable and budget holder; confirm received and queued.
-
T+21: statement of account; invite immediate contact if there is a problem.
-
T+28–30: senior-to-senior note (account manager or director) asking for either payment date or a short plan.
-
Any time a dispute is raised: acknowledge within 1 working day; investigate and respond within 3–5 working days with a clear proposal.
Decision: if you have not followed this cadence, complete it quickly. If you have, and engagement is poor, move forward.
3) What does risk scoring say?
Use a simple risk model combining age, balance, engagement and credit risk:
-
Age: 0–30 days (green), 31–60 (amber), 61–90 (red), 90+ (deep red).
-
Balance vs customer size: >£10k for SME or >£50k for larger accounts is amber/red.
-
Engagement: responsive with dates (green), promises but slips (amber), silence or evasive (red).
-
External signals: adverse filings, director changes, credit score downgrades, CCJs, Gazette notices (amber/red).
Decision: any two reds or one deep red trigger escalation.
4) Are you at the cost-benefit tipping point?
Estimate:
-
Internal cost so far: hours × fully loaded hourly rate.
-
Expected additional in-house cost to recover: more calls, letters, senior time.
-
Third-party cost: agency contingency fee (often 5–20% for B2B pre-legal), fixed-fee letters, or legal fees (some recoverable).
Decision rule: if third-party cost < expected internal cost and likelihood of recovery is higher via external leverage, escalate.
5) Have you met fairness and vulnerability duties?
-
If the debtor is a sole trader or consumer, screen for vulnerability indicators (health, life events, financial capability). Offer breathing-space where appropriate and signpost support.
-
For B2B, still act proportionately and give reasonable timeframes, especially where a bona fide dispute exists.
Decision: if in doubt, seek legal advice before a hard escalation.
6) Have you prepared a clean handoff pack?
Include:
-
Contract/SOW, PO and any change orders
-
Invoices and statements
-
Delivery/acceptance proofs, timesheets, call notes
-
Dispute correspondence and your findings
-
Your preferred outcomes (full payment, payment plan parameters, minimum settlement)
-
Any legal or commercial constraints (service continuation, liens, IP)
Decision: if the pack is complete, handoff now.
7) What is your escalation path and timescale?
Adopt a tiered model:
- Soft external escalate (days 30–45): pre-legal DCA with brand-sensitive approach, SMS/email/phone cadence, authority to agree modest plans.
- Formal pre-action step (days 45–75): solicitor’s letter of claim compliant with the Pre-Action Protocol; offer ADR/mediation if appropriate.
- Issue claim (days 60–90+): MCOL or instructed solicitors; consider statutory interest and fixed-sum compensation; weigh enforceability and costs.
