Keep it in-house if the work is mostly deciding, outsource it if the work is mostly volume, and check first whether the volume is real or just manual. Most businesses considering outsourcing are outsourcing a process problem, and the cost of the process usually falls faster than the cost of the people.
This isn't a two-way choice. A third option changes the numbers more than either of them.
The short version
- In-house keeps the judgement and the relationship. Outsourced buys capacity and distance.
- Businesses affected by late payment spend an average of 86 hours a year chasing it.
- Before you compare cost, check how much of the work is unavoidable. Automatic collection removes most of it.
- Invoices set to collect automatically are paid 98.0% of the time against 90.8% collected on demand (Adfin platform data).
- Outsourcing a relationship-sensitive ledger is the most common expensive mistake here.
The short answer
If your ledger is high volume and low sensitivity, an outsourced team is a reasonable buy. If it's low volume and high sensitivity, keep it close. And in either case, fix the collection mechanism before you decide, because it changes how much work there is to place.
What each option buys you
| Option | What you're buying | What you're giving up |
|---|---|---|
| In-house | Judgement, context, and control of the relationship | Capacity, and cover when someone's away |
| Outsourced credit control | Trained capacity and a consistent process | Context, and some control of tone |
| Debt collection agency | Recovery on debts that have already failed | A share of the debt, and usually the client |
| Software and automation | The repetitive part of the work, removed | Nothing, if the judgement stays with you |
It's worth separating the middle two. An outsourced credit control function chases current invoices as an extension of your finance team. A collection agency pursues debts that have already gone bad. They get confused in conversation and they're not the same decision.
The real comparison
Cost per invoice is the comparison most people run, and it may be the least useful one, because it assumes the current volume of work is fixed.
There are four questions to use as a framework to decide it:
- How much of the chasing is unavoidable? Government research puts the average at 86 hours a year per business affected by late payment. If most of yours is following up invoices you could have collected automatically, you're pricing capacity you don't need.
- How sensitive is the relationship? If your invoices go to clients you also advise, an outside voice on a fee note carries a cost that doesn't show up in the per-invoice price.
- How much judgement does each decision need? Deciding whether to press a good client who's late for the first time is judgement. Sending a reminder on day 8 isn't.
- What happens when it goes wrong? In-house, you hear about it. Outsourced, you hear about it later, from your client.
When outsourcing makes sense
Outsourcing tends to pay off in four situations:
- High volume and low sensitivity, where you've got many small invoices going to customers you don't advise.
- No finance function at all. If the alternative is the founder chasing at 9pm, an outsourced team is better than that.
- A backlog you need clearing once. A one-off aged debt project is a good fit, and a bad reason to sign a permanent contract.
- Genuine specialism, like sector-specific rules or international collection, where the knowledge is worth buying.
When it doesn't
It goes the other way when your invoices go to clients you advise, because an accountancy practice outsourcing fee collection is putting a stranger between itself and its own clients. It also goes wrong when your volume is manual instead of real, since paying somebody to do work that shouldn't exist is the most expensive option on the list.
And there are two cases where outsourcing doesn't take anything off you. If every escalation needs your sign-off anyway, you may have added a step instead of removing one. If one customer is chronically late, you've got a commercial conversation about your pricing or terms, not a chasing problem.
The third option most people skip
It's usually worth changing how the money arrives first, and then deciding what work is actually left to hand over.
Invoices set to collect automatically are paid 98.0% of the time with 0.9% going overdue. Collected on demand, 90.8% paid and 5.3% overdue (Adfin platform data, requests created in the seven months to the end of January 2026). Those two groups aren't identical, because a direct debit mandate is usually behind the first one, and the gap comes from the agreement to collect, not from the effort you spend chasing.
The practical order is: put your recurring work on a mandate, automate the follow-up schedule for what's left, and then look at what's still there and who should do it. Adfin sends the follow-ups on the schedule you set over email, WhatsApp and SMS from your own domain, with core credit control included at no cost.
That usually leaves a much smaller pile of genuinely difficult conversations, which is exactly the work you'd want in-house anyway.
Common questions
Should I outsource credit control? Outsource it where the ledger is high volume and the relationships aren't advisory. Keep it in-house where each decision needs judgement or where the client is someone you also advise. Either way, fix the collection method first, because it changes how much work there is.
What's the difference between outsourced credit control and a debt collection agency? Outsourced credit control chases current invoices as an extension of your finance team. A collection agency pursues debts that have already gone bad, usually for a share of what it recovers.
How much does outsourced credit control cost? It's usually priced per invoice, per account or as a monthly retainer, and the price only makes sense once you know how much of your current workload is avoidable.
Is outsourcing bad for client relationships? It depends whose invoices they are. For transactional customers it's rarely noticed. For clients you advise, an outside voice on a fee note is a real risk.
Can software replace a credit controller? It replaces the repetitive part and not the judgement. The measurable gain comes from automatic collection rather than from automated reminders, and someone still has to decide what to do about the client who has decided not to pay.
What should I fix before deciding? Get recurring work onto a mandate and put the follow-up schedule on a system. Then measure what's left. The decision is much easier when you're placing real work rather than avoidable work.
