Invoice Processing Cost 2026 [Complete Data]

Businesses at the low end of invoicing efficiency spend more than 4 times as much per invoice as businesses at the high end: $6.00 versus $1.42, according to APQC’s Open Standards Benchmarking data reported by CFO.com in 2022. That gap has not closed by 2026 either; APQC’s newest figures still show a spread of more than 3 times in what it costs a business to bill its own customers. This roundup covers what invoicing actually costs, how that cost has moved since 2018, and how it compares to the cost of paying a vendor’s bill.

How much does it actually cost to send an invoice?

Sending a single invoice, once every cost is counted (staff time, technology, overhead, and the back-and-forth of resolving billing questions), costs businesses at the top of APQC’s benchmarking data $1.42 per invoice, and businesses at the bottom $6.00, more than 4 times as much, according to APQC’s Open Standards Benchmarking data as reported by CFO.com in December 2022. The gap compounds fast at volume: APQC’s own analysis of the same data found that an organization could save more than $450,000 for every 100,000 invoices it sends by moving from bottom-performer to top-performer status. This is not the cost of chasing an unpaid invoice, which is a separate problem covered in Unpaid Invoices Cost Small Business $17,500; it is the cost of producing and sending the invoice in the first place.

Has the cost of invoicing gotten cheaper since 2018?

Yes, at both ends of the scale, though the gap between top and bottom performers has stayed roughly proportional. In 2018, APQC’s Customer Credit and Invoicing Open Standards Benchmarking survey of 896 organizations found that top performers spent $2.00 or less to send an invoice, the median organization spent a little under $4.00, and bottom performers spent $9.00 or more. By 2022, both ends had improved: top performers to $1.42, bottom performers to $6.00. Automation and process standardization are the most likely drivers of that decline, a pattern that shows up again below in the accounts payable data on processing time and exception rates.

What does the newest data say about invoicing cost?

APQC’s most recent figures, published by CFO.com in February 2026, measure invoicing cost differently: per $1,000 of company revenue rather than per invoice, a normalization that makes it possible to compare businesses of very different sizes on the same scale. By that measure, businesses at the low-cost end spend $0.19 per $1,000 of revenue to invoice their customers, while businesses at the high-cost end spend $0.62, more than 3 times as much. For a business billing $2 million a year, that is roughly the difference between $380 and $1,240 spent annually just running the invoicing process, an illustrative calculation based on APQC’s reported rate rather than a figure APQC itself published. The direction of the finding matches the per-invoice data above: a wide, persistent gap between efficient and inefficient billing operations.

Is it more expensive to invoice customers or to pay vendor bills?

It is cheaper, on the same per-$1,000-of-revenue basis, to bill your own customers (accounts receivable, or AR) than it is to process and pay a vendor’s invoice (accounts payable, or AP). APQC’s accounts payable benchmarking data, reported by CFO.com in August 2025 and corroborated by APQC’s own blog in March 2026, puts the cost of processing accounts payable at $0.38 per $1,000 of revenue for top performers and $0.92 for bottom performers, which is about 2 times the AR-side top-performer figure and about 1.5 times the AR-side bottom-performer figure. APQC frames the AP-side gap in dollar terms too: a $1 billion-revenue company could save more than $500,000 a year by moving from bottom- to top-performer status on accounts payable alone.

Table 1: APQC’s benchmarking gap across four measurement periods and two sides of the invoice, accounts receivable (billing customers) and accounts payable (paying vendors). Figures are not directly interchangeable across rows since two different normalizations (per invoice, per $1,000 of revenue) are used.

What changes when accounts payable teams automate?

The accounts payable side of the ledger has its own detailed automation data. Best-in-class, highly automated AP teams process a vendor invoice in 3.1 days on average, compared with 17.4 days at less automated organizations, according to Ardent Partners’ 2025 Accounts Payable Metrics That Matter research. The same research found that top-performing AP teams have an invoice exception rate, meaning invoices that need manual review before they can be paid, of just 9%, against a 22% industry average. AI adoption is now mainstream on this side of invoicing too: 75% of AP departments report using some form of AI in invoice processing, per the same 2025 research.

Where does the cost actually go, and what closes the gap?

Across every year and every measurement APQC and Ardent Partners publish, the same pattern holds: cost climbs with the number of manual touches an invoice needs, whether that is a person keying in data, chasing a missing field, or reconciling which of several invoices a payment was actually meant to cover. That last one is a concrete, fixable step. Consolidating everything a client owes into a single statement of account, instead of tracking and following up on each invoice separately, removes exactly the kind of repeated per-document touchpoint that the data above ties to the cost gap between top and bottom performers, on both the billing and the payables side.

Type of manual touch	What closes it
Data entry or a missing field	Standardize invoice format and required fields
Reconciling which invoice a payment covers	Send a consolidated statement of account
Following up on status	Automate reminders instead of manual chasing

The Bottom Line

The cost of invoicing is not a fixed overhead; it is a measurable gap that has held steady, at roughly 3 to 4 times between top and bottom performers, across every year APQC has published data since 2018. The businesses on the cheap end of that gap are not doing anything exotic: they standardize their invoice format, cut down on manual data entry, and reduce the number of separate documents a client has to reconcile.

Frequently Asked Questions

How much does it cost to send an invoice? Businesses at the low end of billing efficiency spend $6.00 to send a single invoice, more than 4 times the $1.42 spent by the most efficient businesses, according to APQC’s Open Standards Benchmarking data reported by CFO.com in 2022.

Has the cost of invoicing changed since 2018? Yes. In 2018, top-performing organizations spent $2.00 and bottom-performing organizations spent $9.00 to send a single invoice, based on a survey of 896 organizations by APQC. By 2022 both figures had fallen, to $1.42 and $6.00, though the roughly 4-times gap between top and bottom performers stayed about the same.

Is it more expensive to invoice customers or to pay vendor bills? Paying vendor bills (accounts payable) costs more at every performance level, about 2 times as much for top performers ($0.38 vs $0.19 per $1,000 of revenue) and about 1.5 times as much for bottom performers ($0.92 vs $0.62), according to APQC’s 2025-2026 benchmarking data reported by CFO.com.

Does automation actually reduce invoice processing time? Yes, substantially. Best-in-class, highly automated accounts payable teams process a vendor invoice in 3.1 days, versus 17.4 days at less automated organizations, and their invoice exception rate is 9% compared with a 22% industry average, according to Ardent Partners’ 2025 research.
