Five leaks. One sit-down. A real number.
Each leak has a one-line description, where to look (Shopify / ShipStation / Stripe / 3PL invoice), the 10-minute test, and the fix. Check the box, fill the $ bleed, get the annualised tally.
Hidden 3PL accessorials
Fuel, dim-weight, oversize and address-correction fees that don’t show on your CPO line. Usually 8–22% off the top.
Real cost-per-order is 30–50% off
What most ops dashboards leave out: chargebacks, returns processing, support time, ad waste on returners. Recompute in one pass.
Carrier SLA misses
Late deliveries you paid express for and never recovered. Most carriers credit if you file inside 15 days.
Stuck orders > 72 hours
Silent backlog that turns into refunds, chargebacks, and 1-star reviews. Often a single bad SKU or 3PL queue.
Returns counted as revenue
The accounting gap that quietly inflates your topline and breaks your true contribution margin.
A tally box for the annualised number
Five $ inputs, one line: your store is leaking $___/year. Most operators hit $40k–$200k.
Built to be run, not read.
Three short steps. No spreadsheet, no SQL, no integrations.

Why these 5 leaks, specifically.
We could have given you 30 things to check. We deliberately didn’t. The 5 leaks in this audit are the ones that show up most often, are easiest to verify yourself in your existing tools, and have the largest dollar impact for stores under $10M GMV. Anything beyond these starts hitting diminishing returns — by the time you’ve fixed all 5, you’ll know whether the broader Instirio detector library is worth running on your data.
The list was distilled from ~200 leaks we’ve quantified across pilot merchants and from the top-cited operational-leakage research (Aberdeen, Forrester, McKinsey CPG ops reports). When the same leak appeared in three independent sources, it made the cut.
What you’ll do with the PDF.
The PDF is a checklist, not a sales pitch. Each of the 5 leaks gets its own page with: the symptom you’d see in your Shopify or 3PL dashboard, the SQL or filter you can run yourself to verify, the typical dollar impact range, and the fix. You’ll spend 20–30 minutes per leak if you do them sequentially.
Most operators run the checklist over a weekend, find at least 2 of the 5 leaking in their store, and either fix them in-house or use the findings as a baseline to compare Instirio’s automated detection against.
The whole document is 12 pages. The 5 leak audits are the first 10. The last 2 are a glossary of the metrics referenced (Perfect Order Rate, Dimensional Weight, Margin Floor, etc.) so you don’t have to keep opening new tabs.
One sit-down. A real number. Free.
