Comparison

Supplier Statement Reconciliation vs an AP Recovery Audit

If your business is small or mid-sized, check supplier statements monthly first. Pay for a recovery audit later, once spend is large and nobody has looked at your old payments.

A recovery audit looks back at what you have already paid. An outside firm usually runs it and keeps a cut of what comes back. Statement reconciliation is your own team checking each supplier’s statement against your ledger every month.

We sell statement reconciliation software, so discount our view. Almost every figure here comes from a firm that sells audits or software, so each figure is named and dated. We found no neutral source for audit fees or for how much of a recovery comes from statements.

Key takeaways

  • A recovery audit looks back at payments already made and is usually paid as a share of what it recovers. Statement reconciliation is a monthly check you run yourself, and it costs staff time or a software plan.
  • One audit firm says about 80% of its recoveries are unapplied or hidden statement credits. Another says 30% of the credits it recovered came through statement reconciliation. They count different things, and both firms sell audits.
  • Vendors quote fees from 10% to 50% and recoveries near 0.1% of spend. On $6,420,000 of annual supplier spend that arithmetic gives $6,420 before the fee.
  • An audit can see overpricing, wrong tax and unclaimed rebates that no statement shows. A statement shows a credit or a duplicate within a month, not after the 677 days one firm reports as the average age of the credits it identified.
  • If you are small, start with statements. Call an audit when spend is large enough for a firm to take you and either nobody has checked your history or much of your spend sits under contract.

What is the difference between the two?

Short answer

What is the difference between an AP recovery audit and supplier statement reconciliation?

An audit is a one-off look back at payments you’ve already made, normally run by an outside firm that takes a share of whatever comes back. Statement reconciliation is you checking, every month, what each supplier says you owe. Both turn up unapplied credits and duplicate payments. Only the audit goes after price errors, tax mistakes and rebates nobody claimed.

Two rows matter most in the table: when the money moves, and what you keep afterwards.

What does a recovery audit actually do?

Westgate Moore, a UK firm, defines it as a retrospective review of supplier payments, looking for payments or credits that should not have left the business. Its guide is clear that this doesn’t replace internal or external audit, and that the firm gives no opinion on your accounts. The job is finding money, and it gets done one invoice, remittance or credit note at a time.

The vendors we read follow roughly the same order. Barcanet lays it out as four phases:

  1. Scoping

    You agree the suppliers, the years and the error types in scope, and who may contact whom.

  2. Data

    You send your payment file, your invoices and the supplier master file. Some firms also ask for contracts and price lists.

  3. Claims

    The firm tests the data, builds a list of suspected overpayments and credits, and takes each to the supplier. Many suppliers send no statement on their own, so the firm often requests one.

  4. Reporting and recovery

    Confirmed items come back as a refund or a credit. You approve the items, post them and pay the firm its share.

Firms also test for prices above contract, wrong tax, unclaimed rebates and missed early-payment discounts, on top of duplicates and unapplied credits. A statement shows almost none of those. It lists what was billed, not what was agreed.

Where the two overlap

A recovery audit usually includes a statement review. Statement reconciliation is the repeatable version of the part that finds credits, and audit firms say a large share of what they recover is credits that sat on supplier statements.

Mostly an audit

Needs contracts or full payment files

  • Price above contract
  • Tax charged wrongly
  • Rebates and allowances never claimed
  • Suppliers who never send statements

Either can find it

The overlap

  • Credit notes not applied
  • Duplicate payments
  • Invoices on one side only

Mostly a statement

Fresh and continuing

  • This month’s credit or duplicate, caught on the next statement
  • Your ledger drifting from the supplier’s
  • Payments the supplier shows as unallocated

Published figures on how much of a recovery comes from statements. Every row is a vendor claim and the samples are different, so the rows cannot be averaged.
Source and dateWhat it saysWho is speaking

Premier Cost Recovery, Q3 2025 brief30% of credits recovered came through statement reconciliation and 70% through other methods. Healthcare clients onlyRecovery audit firm

Xelix, March 2026Recovery firms recover 0.1% to 0.15% of annual AP spend and keep about 20%Software vendor selling against audits

The first two rows seem to disagree. apexanalytix counts a type of credit: about 80% of its recoveries are statement credits. Premier Cost Recovery counts a way of finding them: 30% of the credits it recovered came through statement reconciliation. One sample is healthcare only and the other does not say who it covers. We give no combined range, and you should not average them. The safe conclusion is smaller: statement credits are a large part of what an audit finds, so an audit is partly an outsourced statement review that arrives late.

The third row is the strongest case for audits, so here it is fairly. The company already had a statement tool, and in the firm’s account credits were at times not collected or posted. Finding a credit and collecting it are separate jobs, and in that case the credits were found but not collected.

677 daysAverage age of the credits one recovery firm identified, a little over 22 months

Healthcare clients, one firm, vendor-published. It shows how late credits can surface, not how late yours will. Source: Premier Cost Recovery: AP Signals Brief, Q3 2025, .

That age is the case for the routine check. A duplicate paid in March shows on the supplier’s April statement as a payment with no invoice against it. In an audit cycle it turns up when the project reaches that year.

Statement lane

Monthly routine

  • March: the invoice is paid twice
  • April: the supplier’s next statement shows a payment with no invoice against it
  • You send the supplier the payment date and amount and ask for a refund or a credit
  • Before the next payment run, the credit is in your ledger

Audit lane

One project, later

  • March: the invoice is paid twice
  • Months later: the audit is scoped and your payment file goes to the firm
  • Discovery and claims take months; one firm reports 677 days as the average age of the credits it identified
  • The supplier is asked for a refund or a credit, and the firm takes its share
One duplicate payment, two routes to the same money. An illustrative sequence with no customer data; the audit lane is slower by months, not by a fixed number.

Errors each method can see

These ratings are our reading of how a statement is laid out and what audit vendors say they test. They are not a benchmark, and thin evidence is marked.

Swipe sideways to see every column.

Eight error types against what a supplier statement and a recovery audit can each detect. Our judgement, not a published benchmark.
ErrorOn a supplier statementIn a recovery audit
Duplicate paymentYes, as a payment with no invoice to settle, or a credit balanceYes, from the payment file, even for suppliers with no statement
Credit note not appliedYes, if the supplier lists it and your ledger lacks itYes, and the claim list is usually built partly from statements
Invoice you never recordedYes, it is the supplier telling you what you oweRarely. Audits chase money that left, not liabilities you have missed
Price above contractNo. A statement shows what was billed, not what was agreedYes, if you supply the contract or price list
Tax charged wronglySometimes, if a tax column is printedYes, a standard test
Rebate or allowance unclaimedNoYes, if you supply the rebate terms
Early-payment discount missedRarely. Terms are seldom printed on the statementYes, if terms are in the data you supplied
Paid the wrong supplierSometimes. The right supplier’s statement still shows the invoice openSometimes, if bank details differ from the master file. Evidence is thin for both

What does each one cost?

Audit fees are a percentage of the recovery, so start there.

What audit firms quote

No one publishes a neutral fee. Five vendor pages gave five different ranges, and we have not averaged them.

Swipe sideways to see every column.

Contingency fee shares quoted on vendor pages, read 30 October 2026. All are claims by firms that sell the service or compete with it.
SourceQuoted share of recoveries

Xelix (statement software vendor)About 20%
PRGX, as quoted by Doxalio10% to 40%
ValueXPA25% to 50%

The arithmetic on $6,420,000 of spend

Take a business with $6,420,000 of annual supplier spend, in Australian dollars. PRGX and apexanalytix put audit recoveries at about 0.1% of spend, and Xelix at 0.1% to 0.15%. At 0.1%, an audit recovers $6,420. The next table shows what the firm keeps at each quoted fee share, and what you do.

Swipe sideways to see every column.

Illustrative only: $6,420 gross recovery (0.1% of $6,420,000) at five fee shares. Arithmetic on vendor-quoted rates, not a forecast.
Fee shareFirm keepsYou keep
10%$642$5,778
20%$1,284$5,136
25%$1,605$4,815
40%$2,568$3,852
50%$3,210$3,210

The vendors quote 0.1% as an average across their own clients, so a smaller business could land well away from it. Rever says firms may set a minimum spend or invoice count, but gives no figure. Ring two or three firms before you build a plan on it.

Why recoveries are so much smaller than leakage

Quoted leakage runs from 0.35% to over 2%. Xelix, which sells statement software, says about $3.5 million per $1 billion of spend, which is 0.35%. PRGX, as quoted by Doxalio, says 0.8% to over 2% of annual disbursements. APQC’s median is 1.5% of the number of disbursements, across 1,686 organisations. Watch the unit: PRGX and APQC count payments, not dollars. Apply them to spend and you are assuming a bad payment is the average size. On that assumption, 0.8% of $6,420,000 is $51,360, eight times the $6,420.

Swipe sideways to see every column.

Erroneous payments at three quoted leakage rates on $6,420,000 of spend, set against the $6,420 an audit recovers at 0.1%. The rates are vendor and third-party quotes, applied to spend as a rough illustration.
Leakage rateErroneous payments a year
0.8%$51,360
1.5%$96,300
2.0% (quoted as over 2%)$128,400

No source we read explains the gap. Leakage may count errors caught before payment, while recoveries count only what a firm proved, claimed and collected. We cannot say how much that accounts for.

What the statement route costs

By hand, the cost is your AP clerk’s time. Time the next three statements you reconcile and multiply by your number of suppliers. Software has a plan fee, and the pricing page has the current figures.

A contingency fee costs nothing to sign, so it is easy to agree to. The firm’s share still comes out of the recovery. Put your own spend through the fee table first.

When is a recovery audit the right call?

Hire one when your problem is old payments. These are the signs, in our judgement:

  • Nobody has looked at old payments, or the person who did has left.
  • You changed accounting systems, merged with another business or moved AP to a new team in the last few years, so there is a seam where errors hide.
  • A large share of spend sits under contracts with rebates and tiered pricing: freight, utilities, telecom, retail allowances.
  • Your biggest suppliers do not send statements, so monthly reconciliation has nothing to work from.
  • Spend is big enough that a firm will take you and the maths in the fee table still works.

Before you sign with any firm, get answers to these six:

  1. What is the fee charged on: cash returned, or credits identified?
  2. How far back will you look, and is that written into the agreement?
  3. Which error types are in scope, and which are not?
  4. Who contacts my suppliers, in whose name, and can I veto a supplier?
  5. Will I get a root-cause report so the same errors stop?
  6. Is there a minimum spend or invoice count?

The apexanalytix case in the table above is the argument for an audit even when statements are already covered. The company had a statement tool, and the firm says it still found $850K the tool had not turned into cash. That is the firm’s own account, so treat it as a claim.

When statements are the better first move

Small AP team, suppliers nobody has really reviewed, and you run Xero, QuickBooks Online or Vista? Do the monthly check first. You don’t need a minimum spend to start it, a credit note gets caught the month after it lands instead of years later, and the reconciliation is there if an auditor ever asks for it.

Reconciling the statements every month also helps to show why errors happen. If the same supplier’s statement disagrees with your ledger three months running, it is worth phoning them, and it is also worth looking at how their invoices are being coded on your side. A recovery audit looks back over a past period, so it would find the error, but it would not tell you whether the problem has been put right since.

On the statement, a credit note is a negative line with its own reference. Nothing in your ledger under that reference means you have an unapplied credit. A duplicate looks like a payment line with no invoice against it, or a credit balance. Write down the reference, date and amount, send them to the supplier and ask them to confirm. We put the wording in a separate guide, linked below.

Every difference between a statement and your ledger falls into one of five kinds, and each has its own proof.

It has gaps. A supplier that never sends a statement gives you nothing to compare, so ask for one or sample their invoices. Premier Cost Recovery notes that many suppliers still do not send them unprompted. A price above contract looks like any other price on a statement. A rebate you never claimed leaves no line at all.

Here is that on one invented statement, in Australian dollars, for a supplier called Harlow Packaging. The statement has six lines and your ledger has five. The only line missing from the ledger is credit note CN-4417.

Invented Harlow Packaging statement against the buyer’s ledger, October 2026. Amounts in AUD, GST included.

The balances differ by 1,240.00, which is exactly CN-4417. The duplicate sits on both sides, so it never shows in the gap. You find it only by asking why a payment has no invoice to settle. Nothing in that gap needed a contract, and the missing credit was visible within a month.

Do you need both?

Some do. If you run an audit, run it once for the back history and reconcile statements monthly afterwards, so the backlog does not rebuild. Smaller businesses usually need only the monthly half. The chart turns that into three yes or no questions. We set the size cut-off by judgement, so there is no dollar line.

A decision flow with three questions. Question one asks whether spend is large enough for an audit firm to take you on; a no leads to statements only. Question two asks whether anyone has checked earlier years; a no leads to one audit followed by monthly statements. Question three asks whether much spend is contract-priced with rebates; a yes leads to an audit scoped to those categories plus monthly statements, and a no leads to statements only.

  1. 1You are weighing an audit against statements
  2. 2DecisionIs your spend large enough that an audit firm would take you on?Yes: go to step 3No: go to step 5
  3. 3DecisionHas anyone checked what you paid in earlier years?Yes: go to step 4No: go to step 6
  4. 4DecisionIs much of your spend contract-priced, with rebates or tiered prices?Yes: go to step 7No: go to step 5
  5. 5Statements only. Reconcile monthly and ask the audit firms again when you grow.
  6. 6Audit once for the history, then statements monthly.
  7. 7Audit scoped to the contract categories, plus statements monthly.
Choosing between an audit, statements, or both. The size questions are our judgement, not an industry threshold.

The chart cannot show one more input: whether your largest suppliers send statements at all. If they do not, an audit has more to find, because no routine catches their errors.

Getting the money back once you find it

Either way, you end up talking to the supplier. With a duplicate payment, they are holding your cash as a credit on account. Ask whether they will refund it or keep it against your next invoice, and get the answer by email. The wording and order are in our guide to missing credit notes and duplicate payments.

Record it in your ledger before the next payment run. Otherwise you pay an invoice that the credit already covers, and the same money goes out twice.

An email to the supplier is easier to act on when it contains the following items, in this order:

  1. The invoice or credit note reference, as it is printed on the supplier’s statement.
  2. The date and amount of each payment you made, with the bank reference.
  3. A copy of the remittance advice for each payment.
  4. What you are asking for: a refund to your bank account, or a credit applied to the next invoice.
  5. A reply-by date, usually set before your next payment run.
  6. The name and email address of the person on your side who will post the result.

How often to reconcile is not set by any standard we found, so the following is our judgement. Reconcile monthly the suppliers with the highest spend and the most credit notes, and quarterly the smaller suppliers, moving a supplier up to monthly once a statement shows a credit or a duplicate.

How an auditor sees the two

Auditors treat statement reconciliation as a detective control that runs all year, with a dated sign-off per statement, for example one signed on 5 November for the October statement. A recovery audit is a one-off project, not a control. The audit and SOX side has its own guide.

Mistakes people make with each

Audit mistakes mostly start in the contract. Statement mistakes are about coverage and timing.

With an audit

  • Signing before scope is written down: which suppliers, which years, which error types, and who may contact your strategic suppliers.
  • Not asking what the fee is charged on. Credits identified and cash returned are different numbers, and a credit you never use is not cash.
  • Paying the fee and changing nothing. If the findings show the same coding mistake in forty invoices, the audit has told you where to fix the process. Some firms report root causes. Insist on them.

With statements

  • After the first month, stopping at your top ten suppliers. Small suppliers get less attention, so their credits sit longer.
  • Skipping a statement that shows a credit balance. The supplier owes you, so check for a payment they have not applied, a duplicate or a credit note you have not claimed.
  • Reconciling after the payment run instead of before it.
  • Paying the balance printed on the statement. It is the supplier’s view, so pay approved invoices and use the statement to find differences.
  • Finding the credit and never chasing it. The case study above is the best evidence for this one.

What to do this week

  1. Ask your ten largest suppliers for a statement

    Take the names from your aged payables report, and start with the suppliers that issue the most credit notes. Note which ones send a statement without being asked.

  2. Reconcile the last month for each

    Match every line to your ledger and write down the cause of each difference. Count the credits and the duplicates.

  3. Decide with your own numbers

    If you found real money, use the fee table to see what an audit would add. If you found almost nothing, the audit case just got weaker.

  4. Set the monthly routine

    Agree an owner, a date before the payment run and where the evidence is filed. Our best-practices guide covers this ongoing practice.

Questions people ask

What is an AP recovery audit?
It is a retrospective review of supplier payments, usually by an outside firm, to find payments or credits that should not have left the business. Typical finds are duplicates, unapplied credits, pricing errors and tax mistakes. The firm normally takes a share of what it recovers. It is not an external audit: it gives no opinion on whether your accounts are fairly stated.
How much does an AP recovery audit cost?
Most firms charge a contingency fee, a share of what they recover. Vendor pages we read in October 2026 quoted anywhere from 10% to 50%, and no neutral source exists. Ask what the fee is charged on, cash returned or credits identified, because the two are not the same.
How far back does a recovery audit look?
Vendors disagree. ValueXPA describes a lookback of 12 to 18 months and apexanalytix three years or more. The answer is a scoping decision between you and the firm, and it is limited by what data you can supply and what records your suppliers still hold. Write the lookback into the agreement.
Can I do a recovery audit myself with supplier statements?
You can do the statement-based part. Request a statement from each of your larger suppliers, reconcile it to your ledger, and chase every credit and duplicate. You cannot easily replicate the contract-pricing tests, tax tests and rebate tests, which need price lists and data analysis across several years of payments.
What happens to GST when a supplier issues a credit note?
In Australia the ATO says a supplier generally needs a valid adjustment note before a decreasing adjustment, unless the GST is $75 or less. Whether your own GST credits change is a question for a registered tax agent. A duplicate-payment refund is different, because the original invoice stands. General information, not tax advice.
Do I need both a recovery audit and statement reconciliation?
Only if spend is large enough for a firm to take you and either nobody has checked your history or much of your spend sits under contract. Then one audit followed by monthly statements stops the backlog rebuilding. Smaller businesses usually do better with the monthly statement check alone. At the 0.1% recovery rate three vendors quote, $6,420,000 of spend gives $6,420 before the fee, and firms may set a minimum spend that no one publishes.
What is the difference between a recovery audit and a contract compliance audit?
A recovery audit looks across payments already made for money that should not have been paid, such as duplicates, unapplied credits and wrong prices. A contract compliance audit tests whether suppliers charged what your contract says. They overlap on price errors, and some firms offer both.
What if a supplier never sends statements?
Statement reconciliation has nothing to compare for that supplier. Ask for a statement, ideally monthly, or sample their invoices against your ledger. Premier Cost Recovery notes that many suppliers still do not send statements unprompted, and an audit firm will often request one on your behalf.
