Ask most finance directors how long invoice approval takes at their business, and you’ll often get an estimate rather than a real number, something like “a few days, usually,” or “it depends who’s out of office.” That vagueness is itself a symptom. Approval time is one of the most measurable parts of the AP process, and one of the clearest indicators of where a finance function actually stands. Here’s what reasonable benchmarks look like, what’s usually driving the gap when a business falls short of them, and how PaperLess helps close that gap.
What “Approval Time” Actually Measures
It’s worth being precise about the definition, because it’s often confused with total invoice processing time. Approval time specifically measures the period from when an invoice is ready for sign-off (captured, matched, and routed to an approver) to when that approval is actually given. It doesn’t include the time spent on data entry or matching beforehand. It’s purely about how long an invoice sits waiting for a person to say yes.
This distinction matters because it isolates a specific bottleneck. A business might have excellent automated capture and matching through PaperLess, and still have a slow overall process because invoices sit for days waiting on a department head to check their inbox.
Benchmarks by Company Size
These figures are general guidance rather than fixed rules. Invoice complexity, approval chain length, and industry all affect the realistic target. But as a starting point:
Small businesses (under 50 employees). Approval should typically happen within 24 to 48 hours. Smaller businesses usually have shorter approval chains, often a single approver or owner, so delays are more often about visibility (the approver doesn’t know an invoice is waiting) than about a genuinely complex sign-off process.
Mid-sized businesses (50 to 250 employees). A reasonable target is 2 to 4 business days. At this size, approval chains typically involve a department head plus a finance sign-off for higher values, and delays tend to concentrate around specific approvers who are slower to respond or frequently out of office.
Larger businesses (250+ employees) or multi-entity organisations. 3 to 5 business days is a common realistic benchmark, given more layered approval hierarchies, cost centre or project-based approvals, and often multiple entities or currencies involved. Beyond this range, delays usually point to a structural issue in the approval chain itself rather than individual approver behaviour.
Businesses significantly outside these ranges, a week or more for routine, non-disputed invoices, are usually looking at a process problem rather than a people problem, and it’s worth digging into where specifically the delay concentrates.
What Actually Causes Slow Approvals
No visibility into what’s waiting. If an approver only finds out an invoice needs sign-off by checking an inbox or a shared folder, approval time is effectively determined by how often they happen to look, not by how quickly they’d approve it if prompted.
Approval chains with unnecessary steps. Every additional person in an approval chain adds a potential delay point. It’s worth periodically reviewing whether every step in a given chain is actually adding control, or just adding time.
Approval thresholds that don’t reflect actual risk. Requiring senior sign-off on very low-value, routine invoices adds delay without a proportional control benefit, and often means genuinely high-value invoices compete for the same limited approver attention as low-risk ones.
No mobile or remote approval option. If approval can only happen from a desktop system in the office, that’s a structural bottleneck for any approver who travels or works remotely, which, for most businesses, is now most people some of the time.
Ambiguity about who should approve what. Where responsibility for a particular invoice type or department isn’t clearly defined, invoices can sit unclaimed, with each potential approver assuming someone else will deal with it.
How PaperLess Fixes This
Automatic routing based on clear rules. PaperLess routes invoices to the correct approver automatically based on value, department, cost centre, or supplier, removing the ambiguity about who should be looking at a given invoice.
Real-time notifications. Approvers are notified the moment an invoice needs their attention, rather than needing to proactively check for pending items.
Mobile approval. PaperLess-On-The-Go lets sign-off happen from a phone, removing the “I’ll deal with it when I’m back in the office” delay that affects a significant proportion of approval bottlenecks.
Tiered approval thresholds. Lower-value, low-risk invoices can be routed through a lighter-touch approval process, or approved automatically within tolerance, reserving senior approver time for the transactions that genuinely need it.
Visibility for finance teams. Rather than chasing individual approvers manually, finance teams using PaperLess get a live view of exactly where every invoice sits in the approval chain, and how long it’s been there, whether the business runs Sage, SAP Business One, Orderwise or Xero.
Turning This Into a Practical Improvement
If your business doesn’t currently measure approval time as a distinct metric, that’s the natural first step. You can’t improve what isn’t being tracked. From there, the most common quick wins are addressing whichever single factor is causing the most delay, whether that’s a lack of visibility, an unnecessary approval step, or the absence of an escalation process, rather than trying to overhaul the entire approval chain at once. PaperLess reports on all of this out of the box.
