Mcfly Ads

Your Total ROAS desk

Shopify Total Sales ÷ logged ad spend — then break-even from margin, spend CSV, allocation, goals, and LTV. Confirm margin, add spend from any platform (including billboards), see Total ROAS vs break-even — about ten minutes.

See ad spend next to sales, day by day — the cash desk Shopify Analytics does not give you.

Mcfly Total ROAS desk showing spend, sales, and channel mix

The math

One formula. Two numbers.

Total ROAS = sales (period) ÷ ad spend (same period)

Break-even Total ROAS ≈ 1 ÷ profit margin

Stay above break-even. Shift mix to protect it. Math a CFO will sign.

Decision ritual

Ten minutes.
Same desk every week.

Margin → paste spend → Total ROAS vs break-even → one allocation call. No ad logins. No “which touchpoint won.”

  1. Confirm margin

    Sets your break-even floor: Total ROAS ≈ 1 ÷ profit margin — the number finance already uses.

  2. Paste spend from Sheets

    Shopify Total Sales are already in. Add one day’s spend (Meta or a billboard) or paste a CSV. SyncWith optional — you pay them. No ad-account OAuth. How spend gets in →

  3. Read Total ROAS

    Sales ÷ spend for the same window, vs break-even. Optional 4.0× goal for pacing. Above the floor: protect. At or below: cut or shift.

  4. One allocation call

    Rules-based mix shift with inputs shown — cut, protect, or move budget. Done in about ten minutes.

Spend spine

Three doors into spend.
One Total ROAS.

We already have Shopify sales/orders/LTV. You add spend by day by channel — no Meta or Google OAuth. Daily spend by channel, back to January 2021. Sheets spend guide →

  1. Pick channels → template

    Choose platforms, download a blank CSV (or open in Sheets), fill daily amounts, import on Spend.

  2. Type channel + amount + period

    Day / week / month / quarter / half-year / year — we show “That’s $X/day” before you confirm.

  3. Ads Manager CSV

    Upload an Ads Manager export. Mcfly totals spend against Total Sales. One Total ROAS — not a connector product.

Whole desk: Spend, Overview, LTV, Goals. History back to January 2021. Sample data | Live data — Live = this shop’s Shopify sales + uploaded spend.

Vs connector taxSuites sell OAuth pipes and “Works with” logos before you see a number. Mcfly is paste-first: every named platform plus extras like billboards, no ad OAuth, no connector tax. Automation means you may pay SyncWith-class tools to fill our template — we don’t claim fake partnerships.

After install, Spend accepts paste or file. Sales stay on Shopify.

Know your floor

Break-even isn’t a vibe.
It’s 1 ÷ margin.

Contribution margin sets how far Total ROAS can fall before ads stop making cash and start burning it.

Contribution margin against break-even Total ROAS
Contribution margin Break-even Total ROAS
25%4.00×
35%2.86×
45%2.22×
55%1.82×

Margin at 35% → break-even ≈ 2.86×. This week at 3.2×: above break-even — protect the mix.

At 2.4×: you’re buying revenue at a loss — even if a channel dashboard still looks fine. That gap is the product.

Same sales. Clearer decision math.
