5 reasons why GROW is everything you need to set up & run profitable Google Shopping campaigns
01 · Complete Cost Tracking
CFO-grade product economics
Most accounts bid on products without knowing what each sale is actually worth. MarginStackTM tracks every cost line behind a sale — COGS, shipping, fees, returns, duties, LTV — and adds it up per product, so you see exactly what each sale is worth.
- 15+ costs tracked per SKU, updated automatically
- Sale price to profit per sale, line by line
- Post-sale revenue and LTV added back
02 · Precision Bidding
Precision bids, synced to Google
A blended account target over-pays for weak products and starves strong ones. With true costs known, each product gets its own ROAS bid — recalculated within moments of a price, cost or target change, with the reason logged.
- Recalculated within moments of a change
- Bids move up where margin allows and down where it doesn’t
- Synced to Google Ads automatically
03 · Campaign Efficiency
One SKU, one group, one bid
Grouping products with average bids produces average results. GROW builds campaigns so every nurtured product has its own group and its own bid — at any catalogue size — so Google’s smart bidding gets a clean signal per product.
- No cross-subsidy inside groups
- Winners scale, losers throttle independently
- New products placed automatically
04 · Sales Intelligence
See what every sale did
A sale that lifts revenue can still lose money. Sale impact is tracked automatically — revenue, profit after discount, ROAS and post-sale lift against baseline — so you know what the promotion was actually worth.
- Profit after discount, not just revenue
- Post-sale lift tracked for weeks after
- No manual reporting
05 · Pays for Itself
Outcome-based pricing
Our agents work to get you real, measurable results — pay for tangible, delivered value, not effort. Instead of paying for time, fixed fees, licensing or retainers, GROW fees are based on the value we add — a small fee per sale.
- Agents add their own fee to your bidding — a ROAS bid that generates enough revenue to cover our fee
- Agents grow margin and sales — on average a 14% relative increase in profit margin and 15% – 450% growth in sales
- ~1.5% average fee per sale, scaling down to 0.35% — no retainers, licences or lock-in
