In their words
What clients said after the readout. Every statement sits on a published case; open the case for the audited figure.
“Short version, we were about to cut the wrong thing. Glad we got this done first.”
$134k a year, read a year after a 6 day audit
Contribution margin on the two top campaigns: −7% → +9%
“Revenue grew and cash didn't. Victoria rebuilt margin per order after shipping, returns and payment fees, and our two biggest prospecting campaigns were losing money on every sale. We stopped scaling them.”
Victoria MillerLead auditor on this audit“Founder was on the kickoff call, the auditor who did the work ran the readout. Small thing but I've never had that with a consultancy before. You actually talk to the people who know the answers.”
$118k a year of wasted spend cut in 7 days
Rebates paid on volume never actually earned: 19% → 1%
“Rebate expense outran distributor volume and we could not see why. Cristian reconciled rebates paid against volume actually shipped and paid for, tier by tier: accruals had run off gross purchase orders. Quarterly true ups now catch it.”
Cristian BragauSenior Auditor · signed this audit off“The thing that won me over was a line in the report that basically said "we can't prove this one, so we're not counting it". Nobody does that. Made me trust everything else in there.”
$96k a year of wasted spend cut in 7 days
App installs that funded a real account: 24% → 63%
“Installs looked great and funded accounts stagnated. David followed sign ups through to funding, and the bonus was buying registrations from people who claimed it and never transacted. Incentives now pay on activation, not the download.”
David JacksonSenior Auditor · signed this audit off“I've paid for a few of these "audits" over the years and they usually end with a pitch. This one ended with a list of what to fix and which parts we could do ourselves. Some of it was not what I wanted to hear. All of it was right.”
$92k a year found in 7 days
Enterprise deal margin lost to quarter end: 5 pts lost → 0 pts lost
“Bookings hit target while margin slipped. Cristian split our discounting by timing and rep: concessions spiked in the last days of every quarter because buyers had learned to wait. Approval thresholds fixed it without losing deals.”
Cristian BragauSenior Auditor · signed this audit off“Solid work. Lost a star only because the first week dragged, mostly getting them access on our end so partly our fault. After that it moved fast and the readout was really clear.”
$88k a year of wasted spend cut in 7 days
Paid social proven to lift store visits: ~1 in 3 → 9 in 10
“Our CFO doubted that online ads drove store visits. David's matched market geo lift test proved the doubt right: footfall barely changed where the ads were off. The budget moved to markets and channels that passed the test.”
David JacksonSenior Auditor · signed this audit off$88k annual budget redirection identified in 7 days
Congress spend with a tracked return: 8% → 88%
“Six figures a year in congresses and KOL sponsorships, renewed on habit. Leslie tried to connect it to share of voice, engagement or prescribing and found no instrumentation at all. The unmeasurable part now funds engagement we can track.”
Leslie MartinSenior Auditor · signed this audit off$74k a year of wasted spend cut in 7 days
Courier bonuses paid into already full zones: 22% → 3%
“Incentive spend rose while service levels stayed flat. Alex matched bonus payouts against real time courier availability by zone: in dense areas we paid couriers who would have worked anyway. Bonuses now fire only where coverage is short.”
Alex PopSenior Auditor · signed this audit off$63k a year found in 6 days
Active users actually being billed: 93% → 99%
“Expansion lagged what we saw inside accounts. Victoria reconciled active users against billed seats: many customers used more seats than they paid for. Automated true ups now capture it, and nobody pushed back.”

Qualified inbound calls that became bookings: 2 in 3 → 9 in 10
“Marketing hit every target and revenue stalled. Leslie followed our qualified calls into intake and about a third were dropped at busy times or never followed up. Fixing staffing and call handling converted demand we had already paid for.”
