When Accounts Payable becomes difficult to manage, outsourcing can look like the tempting next step.
Invoice volumes are increasing. Approvals take too long. The finance team spends hours entering data, chasing colleagues and resolving exceptions. Adding headcount is expensive, but leaving the process as it is means delays, errors and an ever-growing administrative workload.
So why not hand Accounts Payable over to someone else?
Accounts Payable outsourcing can reduce the workload carried by an internal finance team. But it does not remove the work itself. In many cases, the business is still paying for invoices to be received, captured, checked, routed and followed up, only by an external team.
AP automation takes a different approach. Instead of relocating repetitive work outside the organisation, it removes that work from the process altogether.
That distinction, relocating work versus removing it, is the one worth understanding before choosing between them.
What is Accounts Payable outsourcing?
Accounts Payable outsourcing means transferring some or all AP activities to an external accountancy or bookkeeping provider’s staff. Depending on the arrangement, this can include invoice receipt and manual data entry, basic checks carried out by staff, chasing approvals, supplier queries and payment-related administration.
The appeal is easy to understand. Rather than recruiting additional employees or asking an already stretched finance team to process growing invoice volumes, the business gains additional capacity by paying another provider’s staff to do the work instead.
That can be particularly attractive when AP has become:
- too time-consuming;
- difficult to scale;
- heavily dependent on manual data entry;
- vulnerable to backlogs when employees are absent;
- expensive to operate internally; or
- a distraction from higher-value finance activities.
What Does Accounts Payable Outsourcing Typically Include?
Not all outsourcing arrangements look the same, but most cover some combination of the following.
- Invoice Receipt and Data Entry
Invoices arrive by post, email or PDF and are keyed into the system by the provider’s staff. Some providers use OCR to assist with scanning, but a person still reviews and enters the data. - Approval Workflow Management
Outsourcing reduces the day-to-day administrative burden, but it doesn’t remove approval bottlenecks. Mismatches and exceptions still need a person to resolve them, whether that person sits inside the business or at the provider. - Payment-Related Administration
Providers may support payment processing, chase supplier queries, and handle other payment-related admin, largely still through manual steps. - Reporting and Audit Support
Most providers issue standard AP reports on a monthly cycle. Real-time dashboards are less common, which means finance teams are often working from information that’s already out of date by the time they see it.
But before outsourcing the process, there is another question worth asking:
Is the problem really that AP needs more people, or that too much of AP still requires people in the first place?

Accounts Payable Outsourcing Pricing: What It Really Costs
One of the most common questions finance leaders ask is: how much does AP outsourcing actually cost?
Common Pricing Models
- Per-invoice pricing based on volume and complexity
- Monthly retainer agreements
- FTE-based pricing for dedicated AP resources
- Hybrid pricing with a base retainer plus overage fees once volume exceeds the agreed scope
Hidden Costs Often Include
- System integrations and maintenance
- Exception handling and dispute resolution
- Supplier onboarding and support
- Expedited payments and special requests
- Reporting customisation
Because these pricing models are built around people, retainers scoped to staff time, FTEs, overage fees tied to volume, outsourcing costs tend to scale with invoice volume: more invoices generally mean more hours, and you pay for them.
That’s worth weighing against the alternative. With AP automation software, cost typically doesn’t scale the same way, since the software absorbs additional volume without adding headcount.
The gap this creates shows up clearly in the numbers. According to Quadient, processing a single invoice manually costs around £10 once staff time, late-payment fees and missed early-payment discounts are accounted for. With the right automation in place, that figure can fall to around £3, roughly a 70% reduction, and it isn’t coming from cheaper labour, it’s coming from touchless processing.
Key takeaway:
Outsourcing and automation solve the same underlying problem in different ways. Outsourcing shifts the labour elsewhere, but the cost structure stays labour-shaped: it scales with volume. Automation changes the cost structure itself, which is why the per-invoice cost can fall as volume grows instead of climbing with it. Before outsourcing the problem, it’s worth asking whether automation solves it first.
Outsourcing relocates the workload. Automation removes it.
Consider a typical manual invoice.
Someone receives it. Someone extracts the information. The invoice needs to be checked, coded and potentially matched with a purchase order or receipt. It must then reach the right approver. If approval is delayed, somebody follows up. If something does not match, somebody investigates.
Outsourcing can transfer many of those activities to another team. Automation changes the workflow itself.
Invoice information can be automatically captured and interpreted. Checks and matching rules can be applied systematically. Approval workflows can send documents directly to the right people, with reminders and escalation rules where necessary. Information can then flow into the organisation’s financial systems without the same level of manual re-entry.
The objective is therefore not simply to process the same workload somewhere cheaper. It is to reduce the amount of manual work required to process each invoice.
That difference becomes increasingly important as invoice volumes grow.
The right model will depend on the organisation. But businesses considering outsourcing primarily because AP is too slow, costly or labour-intensive should compare both options before committing to a long-term service model.
1. Automation can process invoices faster without adding another hand-off
Speed is one of the main reasons businesses look for an alternative to manual AP.
Yet outsourcing introduces another organisation into the workflow. Files, information and exceptions may need to pass between the business and the outsourcing provider’s staff, while service-level agreements determine how quickly certain activities are completed.
Automation removes many of those hand-offs. Once an invoice enters an automated AP platform, data extraction, control, matching and routing can take place as part of the same workflow. Straightforward invoices can progress quickly, while finance employees concentrate on the exceptions that genuinely require their judgement.
Approvers also remain directly connected to the process instead of relying on emails, spreadsheets or communication through an external team.
The result is not simply faster data entry. It is a shorter path from invoice receipt to approval.
2. Automation tackles the underlying cost of invoice processing
Outsourcing can lower staffing requirements internally, but the work itself still has to be paid for. Only now it’s someone else’s payroll instead of yours.
Providers may charge according to invoice volumes, the number of dedicated employees, a monthly service fee or a combination of these approaches. Additional services such as exception handling, integrations or bespoke reporting may also affect the overall cost.
That means a growing business can find that its AP costs continue to rise as transaction volumes increase.
Automation changes the equation because many repetitive activities no longer need to be performed manually for every invoice.
Data does not need to be repeatedly keyed in. Approval reminders do not need to be sent one by one. Routine matching does not need to consume employee time. Documents do not need to be manually tracked across inboxes and spreadsheets.
The more invoices that can move through the process automatically, the less dependent AP becomes on human processing capacity.
For organisations expecting continued growth, this can make automation considerably more scalable than simply adding internal or external resources.
3. Finance keeps visibility and control over the process
Removing administrative work should not mean removing visibility. This is one of the biggest differences finance leaders should consider when comparing automation with outsourcing.
With an outsourced model, AP operations are partly performed outside the organisation. The level of visibility available therefore depends on the provider’s own reporting practices and the information it chooses to share back with the business.
An automated AP platform allows the finance team to remain directly connected to the process. Teams can see where an invoice is, whether it has been approved, what exceptions are preventing it from progressing and who has taken action.
Approval rules also remain embedded in the organisation’s own process. Thresholds, responsibilities and escalation paths can be configured according to internal policies rather than managed informally.
That creates something outsourcing alone cannot provide: less operational workload without giving up operational ownership.
4. Automation strengthens consistency as the business grows
Outsourcing can solve an immediate capacity problem, but it also creates a dependency on an external provider. Changes to processes, approval rules, entities or integrations may need to be coordinated with that provider and, depending on the contract, can affect the scope or cost of the service.
With AP automation, the business retains greater flexibility to adapt its own processes as requirements evolve.
Approval workflows can be adjusted, new entities or users added, and rules modified as the organisation changes, without redesigning the operating model around additional external resources.
This can be particularly valuable for growing or changing businesses, where AP requirements rarely remain static for long.
5. Finance teams can focus on exceptions rather than transactions
One argument in favour of outsourcing is particularly compelling: skilled finance employees should not spend their days entering invoice data and chasing approvals.
But outsourcing doesn’t remove that burden: it just shifts it to someone else’s data entry team. Automation is what actually frees your people from it.
With automation, technology handles the repetitive work while employees retain responsibility for activities requiring financial judgement.
Instead of processing every transaction, AP teams can concentrate on strategy and analysis and on questions such as: Why is this invoice different from the purchase order? Is this duplicate legitimate? Why is a particular supplier generating repeated exceptions? Where are approval bottlenecks appearing? What needs to be resolved before the accounting period closes?
The goal is not to remove people from Accounts Payable. It is to use their time where people actually add value.
Still thinking about outsourcing AP? Ask these questions first
Before selecting an outsourcing provider, finance leaders should assess their existing process.
How much employee time is currently spent on data entry, matching and chasing approvals? How many invoices genuinely require human judgement? Which activities could be automated using predefined rules? How would outsourcing costs change if invoice volumes doubled? Would finance retain real-time visibility into every invoice? Who would control approval rules and exceptions? How easily would the outsourced process integrate with existing ERP and accounting systems?
Most importantly: Are you outsourcing work that technology could eliminate or reduce drastically? Answering that question can change the business case entirely.
Outsourcing AP doesn’t solve the underlying problem: it relocates it to someone else’s team. Automation is what actually removes it.
