The Missing Financial Layer

Linnworks runs your operations. WhatSales makes them profitable.

Linnworks is world-class at inventory and orders. But it was never built to answer: “Am I actually making money?” That's exactly what WhatSales adds.

Side-by-Side Comparison

What you can see, before and after.

The exact financial questions every high-volume Linnworks seller needs answered, and can't.

Financial Question

🟢 Linnworks Alone

🔵 Linnworks + WhatSales RECOMMENDED

Automated COGS

Cost of goods per SKU/order

No automated COGS deduction. You can log purchase prices but true net profit requires manual spreadsheet calculation outside Linnworks.

COGS pulled automatically from Linnworks purchase data. Every SKU's true margin calculated and displayed in real-time, with zero manual work.

Real-Time PPC Tracking

Ad spend vs revenue impact

No native ad spend integration. Amazon Ads, Google Ads and TikTok spend are invisible in Linnworks, so you can't see true ACOS or ad profit impact.

Live ACOS, ROAS and TACoS across Amazon Sponsored, Google Shopping, TikTok Ads and more. See exactly which campaigns are profitable vs burning margin.

VAT & Tax Clarity

Fee & tax impact on margin

Linnworks records orders and fees but doesn't calculate the net profitability impact of VAT, marketplace tax or country-specific deductions at channel level.

VAT, marketplace fees and tax deductions factored into every P&L view automatically. See your true post-tax margin by channel, SKU and date range.

Refund Impact Analysis

Returns & their profit effect

Linnworks processes and tracks returns operationally, but doesn't show you refund reason patterns, their financial impact on margin, or which SKUs are leaking most.

Full refund reason breakdown by volume and value. See which SKUs, channels and return reasons are costing you the most, and take action before it compounds.

Live P&L Statement

True net profit right now

Revenue figures available but no consolidated P&L. You'd need to manually combine Linnworks data with your accountant's spreadsheets to know if you're profitable.

Live, consolidated P&L across every channel, deducting fees, ad spend, COGS, shipping and refunds automatically. Know your real net profit in seconds, not weeks.

Inventory to Profit Link

Stock decisions tied to margin

Inventory levels and reorder points managed well, but with no connection to which SKUs are most profitable. You might be prioritising your worst-margin products.

Inventory decisions powered by profit data. See which SKUs to scale, which to discontinue, and where overstocking is eating margin, with Linnworks data as the foundation.

🔵 WhatSales doesn't replace Linnworks. It makes Linnworks financially complete.
