Sources

If a number is on a FlowSense surface,
the source is on this page.

Every statistic used in FlowSense external content has an entry below: the direct quote, the source, the URL, the methodology, and what the number means and does not mean. If a number isn't here, it isn't on a FlowSense page.

Why this page exists.

The supply chain accountability category has a credibility problem. Vendor marketing pages quote statistics without sources. Industry reports cite each other in circles. Numbers get reformulated in retelling until the original methodology is lost. Operators who buy software based on those numbers get burned when the math doesn't show up in their P&L.

FlowSense is a new category. The handoff problem has not been productized before. Operators looking at us are right to want proof. This page is the proof.

Every external claim FlowSense makes traces to a primary source listed here. Every quote is direct. Every URL works on the day this page was published. When sources update or rot, this page updates. When we add a new statistic to a deck or a page, we add it here first.

I am building this company the way I would want a vendor to build for me. That means showing my work.

Verification method

How a number gets onto a FlowSense surface.

01

Three-tool triangulation

Every claim is checked across three independent AI research tools and corroborated against published primary sources. Where the tools disagree, the most conservative defensible reading wins.

02

Direct source verification

Where possible, the primary document is read end-to-end. The institutional benchmarks cited on this page were verified by reading the original PDF, not by trusting a secondary citation.

03

Scope honesty

Each entry includes a note on what the number means and what it does not. Narrow studies are framed narrowly. Vendor marketing is labeled as such. Adjacent statistics are not used as primary anchors.

Source tiers

Tier 1
Third-party institutional research. Named methodology, named sample size, primary document publicly accessible. Examples: trade association benchmark surveys, named institutional research firms.
Tier 2
Vendor marketing on a vendor's own product page. Useful because the vendor stakes their public reputation on the claim. Flagged because of vendor interest. Used when the claim is consistent across multiple independent vendor sources.
Tier 3
Adjacent or scoped statistics. Real numbers from real sources, but with narrow scope. Used as supporting color when explicitly framed for the right context, never as primary anchor stats.

Revenue exposure to deductions

Tier 2
5 to 7 percent of annual revenue lost to deductions, chargebacks, and compliance fines
"Brands lose 5-7% of annual revenue to deductions, chargebacks, and compliance fines."
Source SPS Commerce, Revenue Recovery product page
Type Vendor marketing
What this means: Across CPG and consumer goods, total deduction load (trade promotions, allowances, chargebacks, compliance fines combined) typically runs 5 to 7 percent of top-line revenue. What this does not mean: This is not the recoverable portion. Most of this is legitimate trade spend or contracted allowances. The recoverable piece is a subset.
Tier 1
Median non-trade deductions: 0.25 to 0.5 percent of sales (203-company benchmark)
"the median response across all respondents was non trade deductions were ¼ - ½% of sales"
Source Attain Consulting Group / Credit Research Foundation 2018 Customer Deductions Benchmark Survey, n=203 companies across 10 industry groups
Type Third-party research, triennial industry benchmark
What this means: When the survey explicitly excludes trade-related deductions (promotions, allowances, markdowns), the median non-trade deduction load (compliance, shortages, chargebacks) is between 0.25 and 0.5 percent of sales. What this does not mean: This is the median; the upper quartile runs higher. Companies with weak compliance discipline can run 2 percent or more.
02

Invalid or disputable deduction rate

Tier 1
Median 5.1 to 10 percent of total deduction dollars are invalid or disallowed
"When asked based on historical information, what percent of total deduction dollars received are invalid or disallowed and charged back to your customers, the median of all respondents is 5.1-10%."
Source Attain Consulting Group / Credit Research Foundation 2018 Customer Deductions Benchmark Survey, n=203 companies
Type Third-party research
What this means: Across 203 companies surveyed in 2018, the median company reported that 5 to 10 percent of total deduction dollars received were invalid (the receiver was wrong, the deduction should not have been taken, the supplier was entitled to the money). The 2018 number was consistent with the 2015 survey. What this does not mean: This is not the disputable percentage in any single deduction category. Shortage claims specifically run higher. Trade-related deductions run lower.
Tier 3
RVCF: 65 to 80 percent of retail shortage claims are invalid (shortage-specific)
"data from the Retail Value Chain Federation (RVCF) indicates that 65% to 80% of retail shortage claims are actually invalid"
Source Retail Value Chain Federation, cited via RetailPath
Type Industry organization, cited via secondary source
What this means: When the deduction category is narrowed to shortage claims specifically, the invalid rate is much higher than the overall median. What this does not mean: This is not the rate across all deductions. The original RVCF document is membership-restricted, so this is currently cited via a secondary source.
03

Recovery rates

Tier 1
Median 60 percent of invalid deduction dollars are recovered
"The median percent of invalid deduction dollars recovered is 60%."
Source Attain Consulting Group / Credit Research Foundation 2018 Customer Deductions Benchmark Survey, n=203 companies
Type Third-party research
What this means: The median company recovers 60 percent of the dollars they have already identified as invalid. The other 40 percent is owed money the supplier is entitled to but never collects, generally because the documentation, the dispute window, or the internal capacity ran out. What this does not mean: This is the recovery rate from the invalid pool only. The recovery rate across all deductions is much lower because most deductions are valid.
Tier 2
Vendor short-ship recovery: 80 percent with documentation, 10 percent without (DSD/c-store specific)
"The difference between operators who recover 80% of their shortages and those who recover 10% comes down to one thing: documentation."
Source DohAssist, vendor short-ship dispute guidance for c-store distribution
Type Vendor advisory content (c-store operations)
What this means: In c-store distribution and DSD specifically, where the receipt is signed in real time at the dock, recovery rate on vendor shortage disputes is roughly 80 percent when the shortage is documented at the handoff and roughly 10 percent when it is not. What this does not mean: This is not generalizable across all deduction categories or all distribution channels. It is specific to vendor shortage disputes where the receipt was signed without notation. We use this stat only when discussing the DSD/c-store handoff specifically.
Tier 2
About half of all disputed deductions are repaid (50+ company survey)
"On average, about half of all disputed deductions are repaid."
Source IAB Solutions data presented at the UpClear CPG Deduction Summit, February 2025
Type Industry conference benchmark, 50-plus company survey
What this means: Of the deductions a CPG brand actually disputes, roughly half come back as recovered dollars. The other half are denied or never resolved. What this does not mean: This is not the dispute rate. Most deductions never get disputed at all. This is the win rate among disputes that were filed.
Tier 2
Realistic recovery baseline: ~10 percent of disputable dollars get back
"On average only 20-30% of deductions are ever disputed by suppliers, yet an average 40% of disputed deductions are won back."
Source SupplyPike (SupplierWiki)
Type Vendor marketing, but math is honest
What this means: Doing the honest math: 25 percent disputed × 40 percent won back = roughly 10 percent of the disputable pool actually recovered. This is the realistic baseline most operators are at today. What this does not mean: This is not a hard floor. Operators with strong process and tooling do better. Operators with no process do worse.
04

Cost to dispute and time to resolution

Tier 2
$300 to $500 in internal staff cost to dispute one $200 deduction
"A $200 deduction may require $300-$500 in internal staff time to resolve."
Source Inmar
Type Vendor marketing, widely cited industry figure
What this means: The internal labor cost to research, build the evidence packet, and file a dispute on a single small deduction frequently exceeds the deduction itself. This is why most operators write off small claims even when they are clearly recoverable. What this does not mean: The cost-per-dispute scales with deduction size. Large deductions are economically worth fighting. The problem is the long tail of small deductions that adds up to seven figures a year.
Tier 2
Finance teams spend 30 to 50 percent of their time on deduction work
"Finance teams spend 30-50% of their time chasing down deduction details across emails and spreadsheets."
Source Inmar
Type Vendor marketing
What this means: A meaningful share of finance and AR capacity in mid-market CPG and distribution is spent on deduction archaeology, not on higher-value work. This is hidden cost that does not show up on a deduction P&L. What this does not mean: This is the average across mid-market companies. Larger enterprises with mature deduction-recovery functions spend less; smaller companies often spend more.
Tier 1
Median 44 days Deduction Days Outstanding
"The median DDO reported across all respondents is 44 days."
Source Attain Consulting Group / Credit Research Foundation 2018 Customer Deductions Benchmark Survey, n=203 companies
Type Third-party research
What this means: Average open deduction dollars stay on the AR ledger for 44 days before resolution at the median company. That is 44 days of capital tied up in disputes that should be resolved or recovered. What this does not mean: This is not the time to file. This is the time the dollars sit unresolved.
Tier 1
Median 90 days from receipt to final resolution
"the median time from receipt of deduction until ultimate resolution is 90 days, or 3 months"
Source Attain Consulting Group / Credit Research Foundation 2018 Customer Deductions Benchmark Survey, n=203 companies
Type Third-party research
What this means: 30 days median to make an initial decision (credit, write-off, or charge back to customer), plus another 60 days median from initial decision to final resolution. By the time the dispute is finally resolved, the original event is three months old and the people who handled it have moved on. What this does not mean: This is the median; the long tail is much worse. 13 percent of companies in the survey reported that more than half of their open deductions were over 90 days.
Tier 1
41 percent of companies cite cross-departmental cooperation as their biggest internal challenge
"When asked about their biggest internal challenge when trying to control deductions, 41% of respondents reported cross-departmental cooperation."
Source Attain Consulting Group / Credit Research Foundation 2018 Customer Deductions Benchmark Survey, n=203 companies
Type Third-party research
What this means: When companies were asked to identify their single biggest internal obstacle to controlling deductions, 41 percent named cross-departmental cooperation. Not technology, not budget, not customer relationships. The handoff between operations, AR, sales, and compliance is where deductions get lost. What this does not mean: This is the named single biggest challenge. Other challenges (resource limitations, tooling) appear lower on the list but still matter.
05

Vertical-specific data

Tier 2
Walmart OTIF: ~3 percent of cost of goods on non-compliant cases
"OTIF performance is tracked at the case level, not just the PO level, and failures typically result in compliance chargebacks worth roughly three percent of cost of goods sold."
Source RetailPath
Type Vendor advisory, confirmed by Walmart's published OTIF policy
Scope note: Walmart is not a current FlowSense direct-sales target vertical. This data is included for context when discussing vendor pain in CPG companies that ship into Walmart. What this means: Walmart's On-Time-In-Full program charges roughly 3 percent of COGS per non-compliant case. What this does not mean: This is the headline rate, not the all-in cost; vendors often see additional administrative fees stacked on top.
Tier 1
Amazon: Nearly all brands receive supply chain chargebacks; 90 percent report incorrect shortage deductions
"In our benchmarking data we found that nearly all brands receive supply chain-related chargebacks from Amazon, and 90% report receiving shortage deductions that are believed to be incorrect."
Source Cleveland Research Company, 2020 Amazon Supply Chain Benchmark, n=74
Type Third-party institutional research firm
Scope note: Amazon is not a current FlowSense direct-sales target vertical. This data is included for context when discussing vendor pain in CPG companies that ship into Amazon. What this means: Amazon vendor chargebacks are nearly universal in the CPG vendor population, and the majority of the shortage deductions are believed by suppliers to be incorrect. What this does not mean: The data is from September 2020 and the sample is 74 companies. The figure has likely shifted in the intervening years; we cite this as it was published.

Retired claims

Numbers we used to use, and don't anymore.

An earlier version of FlowSense ROI material contained three statistics that did not survive verification. They appeared in an internal ROI model, never on a public surface, and were caught by the verification discipline this page describes. We are listing them here because part of integrity is showing what you got wrong, not just what you got right.

5 to 7 percent of revenue lost, attributed to multiple sources Wrong attribution chain
The 5 to 7 percent figure is real and verifiable, but only SPS Commerce supports it directly. Two other sources cited in the original ROI model (CPG Vision and Productiv) do not say what they were claimed to say. Replaced with: SPS Commerce alone, with the Attain/CRF 0.25 to 0.5 percent non-trade benchmark as the conservative anchor.
30 to 40 percent recovery rate without documentation, as a general industry claim Real number, wrong scope
The 30 to 40 percent number is real but only in one specific context: c-store vendor shortage disputes where the receipt was signed without notation. Generalizing it to all deduction categories was not defensible. Replaced with: DohAssist 80%/10% used only with explicit narrow scope. Attain/CRF median 60 percent recovery used as the broader institutional benchmark.
60 percent of deductions are disputable No published source supports this figure
This was a model assumption that got embedded as if it were sourced data. No third-party research supports 60 percent. Replaced with: Attain/CRF median 5.1 to 10 percent invalid (203-company benchmark). For shortage-specific framing only, RVCF 65 to 80 percent of shortage claims invalid.
