Two sides. One stack.

Most Amazon sellers run their business in spreadsheets and do outreach in their inbox. Opero3P puts both in one place — so what you learn from one side makes the other side smarter.

1
Run your business
Sync fees, payouts, and inventory from Amazon's official SP-API. Stack cashback from cards and portals. See real margin per ASIN — not Amazon's misleading "estimated profit." The numbers you'd otherwise be piecing together across five spreadsheets.
FBA management
2
Find new brands
Import brand lists from SmartScout or any CSV. Enrich contacts with Apollo. Build a target list of brands you want to carry — the ones whose products will actually move on your storefront.
Brand sourcing
3
Reach them — without the busywork
Send sequenced campaigns from your Gmail. Personalized to each brand and contact. Opero3P handles the sending schedule, daily caps, and follow-ups automatically.
Outreach
4
Handle replies in one inbox
Replies land in a unified inbox, tagged by AI as interested, objection, out-of-office, or not interested. Click "Suggest reply" for a drafted response. Move warm leads forward without losing track of anything.
Reply handling

Everything you'd pay a VA $400+/month to do.

Outreach is the work most FBA sellers either skip or hire a VA for. Opero3P does the heavy lifting so you can run real outreach yourself — or run more of it than a VA ever could.

🎯
Brand list management
Track every brand you're working — researching, contacted, replied, won, lost. Import from SmartScout or any CSV. Quick filters surface brands that have contacts but haven't been reached yet.
Templates & campaigns
Build email templates with merge fields. Run sequenced campaigns with initial + follow-ups, day offsets between them, and daily send caps. Each contact gets a personalized email — never a copy-paste blast.
📬
AI-classified inbox
Replies are pulled in automatically and tagged: interested, objection, not interested, out of office, unsubscribe. Sort by what matters. Suggest-reply drafts a response in your voice.
📊
True margin tracking
Daily SP-API sync pulls your real Amazon fees per ASIN. StackBuddy Chrome extension pushes fees from the FBA Calculator. See net margin after all costs — including the cashback you stacked.
💳
Cashback stacking
Track unlimited cashback sources — credit cards, shopping portals, gift card programs. Stack every layer on every order. See what your real cost of goods is, not what the receipt says.
🏪
Multi-store, payouts, supplier analytics
One login, multiple Amazon stores. Payout calendar so nothing surprises you. Supplier breakdowns showing which sources actually make you money. Everything in one place.

Less than 10 hours of a VA.
Plus your whole FBA toolkit.

A decent VA running outreach for you costs $400–$800/month. Opero3P costs $49 for the life of your membership — and you get the daily FBA tools (margins, payouts, cashback, inventory) on top of it. Two products' worth of value, one subscription.

Common questions

What does the outreach side actually do?
You connect your Gmail. You build a list of brands you want to carry (import from SmartScout or any CSV). You enrich contacts with Apollo. You write a couple of email templates. Opero3P sends sequenced campaigns — personalized per brand and contact — at the daily rate you set. Replies come into an AI-tagged inbox so you can prioritize interested brands and ignore the rejections. It's exactly what a competent outreach VA does, without the management.
What does the business side actually do?
It's the daily-use FBA toolkit. SP-API connects once and auto-syncs your fees, payouts, inventory, and listing data every day. Multi-source cashback tracking stacks every rebate you earn — credit cards, shopping portals, gift-card programs — to show what your real cost of goods is. Margin calculator shows net profit per ASIN after every fee, including the cashback. Payout calendar, supplier analytics, multi-store support, and the StackBuddy Chrome extension are all included. If you do nothing with outreach, this is still the FBA tool you'd be using every day.
How does the free trial work?
14 days of full access. You'll enter a card to start the trial, but nothing is charged for 14 days. To keep email sending fair during the trial, sends are capped at 50 during the trial — enough to run a real test campaign on a small brand list. Cancel anytime in those 14 days and you won't be billed.
Why $49/month for the first 50 customers?
It's launch pricing. We want serious early customers — you're getting in before the product fully proves itself in market. In exchange, your $49 rate is locked in for the life of your membership. As long as you stay subscribed, your price never goes up — even when standard pricing rises. Sign up after the 50th customer and it's $59/month.
Do I need any other tools to use Opero3P?

For outreach: an Apollo account (any paid plan starts at ~$49/mo) for contact enrichment, and optionally MillionVerifier for email verification. You bring your own keys — this keeps Opero3P inexpensive and means your enrichment budget is entirely yours, not bundled at our markup.

For brand sourcing: any CSV will work, but if you use SmartScout, the CSV export feature requires their Business tier. Lower SmartScout tiers can still copy/paste brand lists into the importer.

For Amazon: just your Seller Central account. The SP-API connection is handled through Amazon's official OAuth flow — no other tools needed.

Is the Amazon integration official?
Yes — through Amazon's official Selling Partner API. Connect your account once via OAuth and Opero3P auto-syncs your fees, inventory, and listing data every day. You can refresh any ASIN on demand, and disconnect in one click anytime. Refresh tokens are encrypted at rest.
What's StackBuddy?
A companion Chrome extension included with your subscription. It pushes fees from Amazon's FBA Calculator into your dashboard with one click (including storage fees the SP-API doesn't expose), and lets you research ASINs you don't yet own. Optional — the app works without it.
Multi-store accounts?
Yes. Each store gets its own isolated dashboard, data, and outreach — all under one login. Switch between stores with one click.
Can I cancel anytime?
Yes. Cancel from your account or by emailing support. No contracts, no cancellation fees. If you cancel mid-month, you keep access until the end of your billing period.
Is my data safe?
Stored in an encrypted cloud database (Supabase). Only you have access via your sign-in. Gmail tokens and API keys are encrypted at rest. You can export everything anytime and delete everything anytime.
