↑ $180K from overstocked SKUs · $148K from 3PL optimization · $212K from hidden COGS
"Before Spartiate, I had no idea what my real margins were per SKU. Now I can see my unit economics in real time. I finally feel like a CEO — not just a fulfillment coordinator."
↑ Lender-ready in 90 days · Deal closed in 6 weeks · 3× ROI on audit fee
"My accountant was doing bookkeeping. Spartiate built me a financial operating system. There's a massive difference — and it showed when I walked into the bank."
↑ $820K in profit found · Exit-ready in 90 days · 205× ROI on audit fee
"Our broker quoted us one number. After Spartiate rebuilt our financials, he came back and listed us for significantly more. That bump is money I walked away with."

We run a deep audit of your Seller Central data, P&L, inventory, and COGS. Most clients discover $200K–$1M+ in hidden profit they didn't know existed.

We build your full Financial Operating System™ — real-time P&L, rolling cash flow, inventory reorder engine, and SKU-level unit economics. Live in 90 days.
We DON'T use generic spreadsheets built for restaurants — everything is calibrated to Amazon FBA and DTC economics.
On retainer, we maintain the system, update models monthly, and advise on every major financial decision — from capital allocation to fundraising to exit.
We DON'T just produce monthly reports — we think like investors and act like partners.

"I was running a $2M brand with a spreadsheet my VA built in 2019. Within 45 days, I had a real CFO-grade system. I finally know where every dollar goes."
"The cash flow model alone paid for the engagement. We avoided a stockout that would have cost us $80K in Q4. Non-negotiable for any serious seller."
"My financials were a disaster. Spartiate got us lender-ready in 60 days. We closed a $750K round in 5 weeks. Worth every dollar."
"My accountant did my taxes. Essama built me a financial cockpit. There is no comparison. This is what operating a real business feels like."
"As a 7-figure seller you'd think I had my finances dialed. I didn't. FOS™ Operator is the best investment I've made in the infrastructure of my brand."
"The inventory model reduced tied-up capital by 31%. That's real money we're now deploying into growth instead of sitting in a warehouse."
