Tuesday, 9:14 AM. Your supplier's new price sheet lands.
TS-BLK-M cost +$1.40By 9:15, the margin math is already done.
It crosses your floor. You get one email.
Built to be trusted with your numbers.
None of this is a setting you have to find. It's how the product is built.
Read-only, always
Marginova requests read_products and read_inventory — nothing else. It can see your catalog; it can never edit a price or push a change back to your store.
Stripe handles every card
Checkout and billing run on Stripe's PCI-compliant infrastructure. Marginova's code never touches — or stores — a card number.
Your numbers, walled off
Row-level security on every table scopes each query to your account at the database layer. There's no code path from one seller's data to another's.
Cents, not floats
Cost, price, and margin are stored as integer cents end to end. No floating-point rounding drift between what you typed and what you see.
Who Marginova is for
Built for sellers who pack their own boxes.
Marginova is for solo and small teams running 20 to 1,000 SKUs on Shopify, Etsy, or Amazon — the sellers doing their own packing, their own pricing, and their own books. Not a finance team. Not a merchandising department. Just you, a spreadsheet that got out of hand, and margins you'd rather not find out about at month-end.
Your first alert is five minutes away.
Bring the cost sheet you already keep and set one rule. That's the whole setup.

Margin alert — TS-BLK-M
Cotton tee margin dropped to 11.5% — below your 15% floor. Cost rose from $6.90 to $8.30 on your supplier's latest price sheet.
Margin over 12 days
the system
A ledger that speaks up.
Everything watches your floor — nothing needs babysitting.
alerts · digest
One email the moment it matters.
One email the moment a net margin — after fees and shipping — crosses below its floor. Once per crossing, no repeat spam while it stays low. A daily digest rounds up everything below threshold, plus where you have room to reprice.
repricing
See where you have room to move.
Products whose margin runs well above the floor get flagged — room to move price without breaking your rule.
csv · shopify · links
Your catalog, in however you keep it.
Type products in, or drop a CSV — rows update by sku. Or connect Shopify and prices and costs sync themselves — read-only, synced daily, plus Sync now anytime on Growth and Scale. Keep a competitor URL beside each product for reference; Marginova never scrapes.
floors
One rule, enforced everywhere.
A store-wide default, with per-product overrides where a product needs its own rule.
the old way
The spreadsheet was fine. Until it wasn't.
Marginova is the ledger you already keep — with a watchdog attached.

The short answers.
Where does the price data come from?
From you. Add products by hand or upload a CSV of the cost sheet you already keep. Competitor URLs are stored as reference links next to your products — Marginova never scrapes marketplaces.
What happens after the 14-day trial?
Your subscription starts at $19/month on the card you entered at checkout. Cancel before the trial ends and you pay nothing.
How do I cancel?
From Settings, open the billing portal and cancel there. It's Stripe's own portal — no emails, no retention flow.
What does the CSV need to look like?
A header row of sku,name,cost,price, with optional competitor_url and min_margin_pct columns. Re-uploads update existing rows by sku.
What Shopify permissions does Marginova ask for?
Two read-only scopes: read_products and read_inventory. Marginova pulls prices and costs on a daily sync (or on demand with Sync now) and never requests write access.
Can I switch plans later?
Yes. Open the billing portal from Settings and pick a new plan — Stripe handles the change and any prorated charge on your existing card.
What happens if I go over my plan's product cap?
New products are blocked until you delete one or upgrade — nothing you've already added stops being monitored.
Stop finding out at month-end.
Set your floors once. Marginova watches every price and cost change after that.
