The short answer: evaluate each candidate on six criteria — relevant commercial experience, communication, reporting, data handling, fees, and contract terms — then compare the answers side by side. No single call or price quote is decisive; the pattern across all six is what you are judging.
Choosing a provider is a filtering exercise, not a search for a perfect answer. Two agencies can be competent, well-run businesses and still be wrong for your accounts — one may be built around consumer work, another around volumes far above yours, another around terms you would not sign. The way to sort this out is to ask every candidate the same six questions, in writing where possible, and keep the answers. This article is the checklist; the companion guide to hiring a collection agency places it in the wider decision.
The evaluation checklist
Use this as your first pass. A candidate that cannot give a clear, specific answer in these areas early on rarely improves after the contract is signed.
| Criterion | What a strong answer looks like | Warning sign |
|---|---|---|
| Relevant experience | Hands-on work with commercial (business-to-business) accounts like yours, and comfort with your level of documentation | Experience described entirely in consumer terms, or no clear answer on accounts of your size and complexity |
| Communication | A named contact, agreed response times, and disputes or disputes-in-progress routed to you rather than handled unilaterally | You cannot tell who will handle the account or when you will hear from them |
| Reporting | A defined cadence with activity notes, status changes, and a remittance statement you can reconcile against your own records | General assurances with no sample report and no schedule |
| Data handling | Secure transfer, limited internal access, defined retention, and a stated position on what happens to your data at the end | Files requested as ordinary email attachments with no explanation of storage or access |
| Fees | The fee structure in writing, every deduction and expense listed, and a worked example on a balance like yours | A headline rate with no statement of what it applies to or what else is charged |
| Contract terms | Clear term, cancellation mechanics, treatment of placed accounts, and settlement authority written down | Long auto-renewal, an exit path you cannot find, or refusal to put authority limits in writing |
Relevant experience
Not all collection experience transfers. Commercial and consumer work differ in the evidence they turn on, the pace they move at, and the rules that may begin to apply — worth a primer in the differences between commercial and consumer debt collection before you take any meetings. Within commercial work, ask what share of the accounts they place are business-to-business, whether they handle balances and documentation structured like yours, and what they do when a file has gaps. Experience with accounts of your type matters more than years in business alone: an agency that mostly sees small, clean, well-documented invoices may treat a larger, partly disputed file very differently. Ask directly how they handle an account that turns out to be genuinely disputed or thinly documented. A candid answer — including a willingness to tell you an account is not ready — is itself a data point about how they work.
Communication
You are handing a third party conversations with your customers, so the way they communicate is the way your business will sound. Establish who your contact will be — a named person or a monitored team inbox — and the expected response time for questions. Ask how often you will hear from them by default, how they relay payment promises and disputes, and what channels they use. Two further checks are worth making: how they document telephone contact and whether those notes reach your file, and what happens when something needs your decision — does the account wait days for a reply, or is there an agreed escalation path? Their tone with debtors should be firm and professional; they are representing your business whether you are in the room or not.
Reporting
Reporting is how you verify that work is actually happening. Ask what you will receive and how often: a placement confirmation, periodic activity summaries, status changes (promise to pay, dispute raised, debtor not located, recommended escalation), and a remittance statement that reconciles gross collected, deductions, and net paid to you. Request a sample of each before you sign — a sample report costs them nothing and tells you a great deal. Ask whether reports arrive by email, portal, or both, and whether the fields line up with your own aging so reconciliation is mechanical rather than detective work; our piece on the accounts receivable aging report lists the fields that make that easy. Also agree what happens if a report does not arrive: who do you call?
Data handling
Your file contains contracts, invoices, statements, and contact details — and sometimes personal details of individuals at both companies. Ask how files are transmitted (a secure upload is a different thing from an email attachment), where they are stored, who inside the firm can access them, and whether access is reviewable. Ask how much they retain after an account closes and what happens to your data when the contract ends: returned, retained for a period, or destroyed. Two direct questions are worth putting in writing: whether account data is shared with outside vendors or subcontractors, and how clients are notified if a security incident affects their files. Send only what proves the debt — the documents checklist for commercial debt collection explains what belongs in a collection file and what does not.
Fees
Fee structures vary: a contingency charge calculated on money actually recovered, flat or placement charges, time-based charges, and hybrids. What matters is not which label appears on the proposal but how the amount is calculated, what is deducted before you are paid, and when funds reach you. Ask for the structure in writing, a worked example on a balance like yours, a list of expenses that may be billed separately, and the terms governing settlement authority — whether the fee is figured on the full invoice or on the amount actually received. The mechanics are set out in commercial collection agency fees, and the contract language behind contingency promises is unpacked in what does no collection, no fee actually mean. Compare structures, not headline rates: a lower percentage inside a contract with broad expense pass-through can pay you less than a higher one with clean terms.
Contract terms
Read this before deciding, not after. Key provisions: the term and how renewal works (watch for automatic renewal with a narrow cancellation window), the notice period and method required to cancel, and what happens to accounts already placed if you leave. Some contracts carry obligations that continue after cancellation — for example, charges tied to payments received on placed accounts later on. Check how settlement authority is expressed, whether referral for legal review requires your instruction and prior approval of costs, who is regarded as owning the claim, and what happens to your data at termination. If a clause is not clear to you, ask for a short plain-English summary in writing and keep it alongside the contract. The reading method in questions to ask a collection agency before hiring it gives you the full interview order.
Comparing candidates side by side
Run it the way you would run a hiring process — same brief, same questions, same evidence:
- Write your requirements first. Reporting cadence, contact expectations, authority limits, escalation preferences. You cannot judge answers until you know what you need.
- Give every candidate the same brief. Use the same example account and the same written question set for each, so differences in the answers are real rather than artifacts of different scenarios.
- Score each criterion 1 to 5, with a note of the evidence. A score without a note is an impression; a score with a note is auditable later when you have forgotten the call.
- Weight experience with accounts like yours and contract terms above price alone. Price is one input; the terms determine what you actually receive.
- Verify rather than assume. Ask for a sample report and a sample fee calculation, check whatever public business and complaint records apply in your jurisdiction, and ask for references from businesses with similar accounts if the firm offers them.
- Shortlist two and compare the actual contracts. The pattern across all six criteria picks the shortlist; the contract text picks the winner.
| Criterion | Score (1–5) | Evidence from their answer |
|---|---|---|
| Relevant experience | ||
| Communication | ||
| Reporting | ||
| Data handling | ||
| Fees | ||
| Contract terms |
Work one copy per candidate. The evidence column is the point of the exercise: it is what you will read back when two scores land close together.
Warning signs worth taking seriously
- Guarantees of recovery, rates, or timelines — no one can guarantee an outcome they do not control.
- Pressure to sign before you have been given the contract to read.
- Refusal or inability to explain deductions, or to show a worked example.
- Vague answers about who handles the account and what reporting you will receive.
- Large non-refundable upfront charges with no clearly described service attached.
- Reluctance to answer written questions — you want a record, and a firm confident in its process will provide one.
- No interest in the state of your documentation. A provider that places any account you send without asking what proves the debt is telling you something about its process.
Next steps
Shortlist with this checklist, then run the full interview worksheet against both candidates and read the money articles — how fees work and what contingency language really means — before the contract reaches your desk. If you are still weighing whether to outsource at all, start with in-house collections vs. a collection agency, and for the wider decision framework see our guide to hiring a collection agency. When you are ready to look at a specific account, you can submit it for review.
