About FLC Multiple Warehouse

Why we built it

Every multi-channel inventory business eventually hits the same wall: the platforms (Amazon, Shopify, Walmart) report sales by SKU but not by warehouse. QuickBooks Online wants one number for Cost of Goods Sold per period, not a spreadsheet of cost layers. And the spreadsheet someone built three years ago to bridge the two has quietly drifted out of sync with reality.

FLC Multiple Warehouse is the missing layer. We pull bills from your accounting platform, build per-warehouse FIFO cost layers, allocate freight and storage as they're incurred, and post one clean COGS journal entry back to QuickBooks Online at month-end. Inventory on the balance sheet matches the count on the floor. COGS on the P&L matches what shipped. The auditor sleeps.

Who we are

FLC Multiple Warehouse is operated by Four Lines Capital Management, LLC, a Nevada-domiciled investment and operations company with a long history of building internal accounting tools for portfolio companies in distribution, fulfillment, and consumer brands. We're not a venture-funded SaaS shop chasing a billion-dollar exit. We built FLC Multiple Warehouse for our own portfolio companies first, then realized other operators were facing the same problem, and decided to share it.

That informs the product:

• We're not selling features, we're solving an accounting problem. Every line of code traces back to an actual journal entry in an actual general ledger. If it doesn't, we don't ship it.
• We're independent of Intuit. We integrate with QuickBooks Online because that's where our customers' books live. We're not affiliated with, endorsed by, sponsored by, or certified by Intuit Inc.
• We charge a flat monthly fee, not per-transaction. The volume of bills, sales, or warehouses doesn't change the price. You'll never get a surprise bill in the busy season.

What the product does

1. Pulls cost basis from your accounting platform

Bills coded to inventory items become cost layers (FIFO). Bills coded to overhead accounts (storage, freight, broker fees) become allocable overhead, distributed across the warehouses that received them.

2. Reconciles platform sales to physical movement

Amazon, Shopify, and Walmart sales reports get matched to your warehouse outflows. Discrepancies surface for you to investigate — they're not silently absorbed.

3. Calculates COGS using true landed cost

Per-unit landed cost = invoice cost + allocated freight + allocated storage + allocated broker fees. COGS uses the FIFO layer that was in front when the unit shipped. You can override per-product before posting, with a reason captured for the audit trail.

4. Posts one clean journal entry

One Cost of Goods Sold journal entry per period, in aggregate or split per warehouse. Idempotent — re-running won't duplicate. You review and approve every entry before it touches your ledger.

5. Sends a monthly recovery statement

Every month, you receive an email with a complete transaction statement: every bill consumed, every sale shipped, every adjustment posted. If FLC Multiple Warehouse disappeared tomorrow, you'd be able to reconstruct your inventory ledger from that one file. Your data is yours.
