Don't get fooled

5 mistakes operators make when choosing

Mistake #1 — Reading gross margin and calling it profit

Gross margin hides Amazon fees, ad spend, 3PL, and returns.

Fix: Demand contribution margin by SKU and channel.

Mistake #2 — Buying a SaaS-built FP&A tool for an inventory business

Mosaic and Vena have no real concept of COGS or inventory turn.

Fix: Pick a tool with native Shopify, Amazon, and a COGS model.

Mistake #3 — Skipping Amazon fees in the channel P&L

Referral, FBA, and storage fees can eat 30 percent of revenue.

Fix: Roll every Amazon fee line into channel contribution margin.

Mistake #4 — Tracking ad spend in one tool and margin in another

Meta and Google ad spend sit outside the P&L, so blended margin is wrong.

Fix: Pick a tool that pulls ad spend into contribution margin.

Mistake #5 — Ignoring inventory turn until cash runs out

Stock sitting in a 3PL is cash you cannot spend.

Fix: Track days-on-hand and inventory turn weekly.

FAQ

Common questions

What is the best FP&A for ecommerce in 2026?+

For $1M-$50M brands on Shopify and Amazon, Fairview scored highest (9.4/10).

How much should an ecommerce brand spend on FP&A software?+

Median spend for a $5-15M GMV brand is $3,400/year.

Why is SaaS FP&A wrong for ecommerce?+

SaaS tools track ARR and burn. Ecommerce needs COGS, fees, ad spend, and inventory turn rolled into contribution margin.

Cube vs Mosaic vs Fairview for an ecommerce brand?+

Fairview is best for $1M-$50M Shopify and Amazon brands. Cube fits once you have a finance lead. Mosaic is built for SaaS and skips inventory.

Can I just use QuickBooks plus a spreadsheet?+

Up to about $1-3M GMV, yes. Past that, channel and SKU margin fall apart in a spreadsheet.

How long does setup take?+

Fairview 15 minutes. Cube 2 weeks. Pigment 4-8 weeks. Anaplan 12+ weeks.

Does the tool need to connect to Amazon Seller Central?+

Yes, if you sell on Amazon. Without native Amazon, fees and FBA costs miss the P&L.

What about Pigment or Anaplan?+

Both are enterprise FP&A. Wrong for brands under $50M GMV.

What ecommerce KPIs should an FP&A tool show?+

Contribution margin by SKU and channel, blended CAC, inventory turn, days-on-hand, return rate, and cash runway.

What if I outgrow the tool?+

Fairview scales to $100M GMV. Past that, most brands move to Pigment or NetSuite Planning.
