The problem: scaling Meta with foggy unit economics
Most Shopify sellers watch ROAS and feel “in the green.” Fewer know what they actually keep after discounts, payment fees, expected refunds/chargebacks, support time, shipping/COGS, and app overhead — the contribution that funds ads.
Without that number, break-even ROAS is a guess. Allowable CAC is a vibe. Experiment budgets are “whatever feels safe.” That fog is expensive when Meta spend climbs.
What’s at stake when CAC is wrong
- Silent bleed: campaigns that “work” on ROAS while contribution after fees is thin or negative.
- Overpaying for customers: CAC above what the offer can fund once real costs are counted.
- Endless testing without floors: creatives and audiences rotate while max test spend has no contribution-based cap.
- False confidence: scaling a winner that only looked like one because unit economics were incomplete.
The solution: ContribDesk
ContribDesk is a decision-grade Excel unit-economics & experiment kit for Shopify / DTC operators. It walks you from offer assumptions → pre-ad contribution → break-even ROAS → allowable CAC → experiment caps — so you set floors before spend climbs.
Not a $19 junk template dump. Not a live Shopify sync app. Not a promise of ad profits. An operator workbook you own after one purchase.
Screenshot shows workbook UI. Demo numbers are labeled EXAMPLE — illustrative only, not live store revenue.

EXAMPLE numbers inside the workbook are illustrative wiring checks — not your store’s revenue.
FAQ
Do I need advanced Excel skills?
No. Peach cells are inputs; green cells are calculated. If you can enter price, fees, and rates, you can use the kit. Excel (desktop / Microsoft 365) recommended.
Does it live-sync with Shopify?
No. ContribDesk is an Excel kit you download. No Shopify API sync, no automated order import.
Can I get a refund?
No. Digital downloads are all-sales-final. If delivery fails, we re-send the file. See the Refund Policy.
Are the sample numbers my store’s revenue?
No. Demo rows are labeled EXAMPLE — illustrative only. Replace them with your assumptions and orders.
Mac or Windows?
Both. Use Microsoft Excel on Mac or Windows (or Microsoft 365). LibreOffice / Google Sheets import may work but is not runtime-verified for every feature.
Will this make my ads profitable?
No kit can promise that. ContribDesk helps you model floors (contribution, BE-ROAS, allowable CAC) before you spend. Results depend on your offer, traffic, and execution.
