Too many tools
Selling on Amazon shouldn't take five logins and a spreadsheet.
Most sellers piece together a calculator, a repricer, an inventory tool, a profit tool and a pile of sheets. None of them know what the others know.
- Checking one ASIN at a time to see if you can even sell it
- A buy sheet and a storefront sheet you update by hand
- A repricer that doesn't know what you paid, so it can price you into a loss
- Lost and damaged units nobody claims, because finding them takes a weekend
- Not knowing what you actually made until your accountant tells you

Monthly prices checked Oct 31, 2026: the SellerAmp plan I used and each other tool's lowest plan. Most sellers are on a higher tier, and prices change often, so check each vendor. Opero3P uses your own Keepa key for market data. Add up your own stack and your time →

Who built this
I sell on Amazon. I built the tool I couldn't buy.
I run an FBA business, and for a long time my sourcing loop lived in four tools and a pile of spreadsheets: one to check gating, one to vet, one to reprice, and a weekend every month to work out what I'd actually made.
Opero3P is that loop in one place, built on the numbers I use in my own account every day: what I really paid, Amazon's real fees, and whether I'm allowed to list the thing at all. The books side was built and tested with a professional bookkeeper on a live Amazon business.
If you get stuck, email me. It's my inbox, not a ticket queue.

Free Chrome extension
Bob for Chrome is free. Yours to keep.
Most tools charge every month just to show profit on an Amazon page. Bob for Chrome does it free, with a free Opero3P account, whether or not you ever subscribe.
- Can you sell it? Checked on your own Amazon account, not a guess.
- Real profit and ROI after Amazon's referral and FBA fees, for your cost.
- 30 lookups a day, free. Unlimited, plus what you paid last time, market data and Bob's take, with Opero3P.
Works in Chrome, Edge and Brave on a computer.
Repricer
A repricer that knows your real costs.
Most repricers only see the Buy Box. Opero3P sees what you actually paid, so it chases the Buy Box without pricing you into a loss. Every line below is from the app's own activity log on one real listing.
- 6:28 PMNo change6 other Prime sellers within 1% of the $18.78 Buy Box, so Amazon rotates it. Not undercutting.
- 4:00 PMPrice changed$18.79 → $18.78 · Match the Buy Box (crowded listing)
- 3:15 PMPrice changed$18.47 → $18.73 · Match the Buy Box (crowded listing)
- 2:30 PMLost the Buy Boxyou $18.47 · Buy Box $18.49
- 2:15 PMWon the Buy Boxyou $18.47 · Buy Box $18.47
- 2:00 PMPrice changed$18.65 → $18.47 · Step back
- 1:45 PMPrice changed$18.47 → $18.65 · Creep up
- Match, creep, step back. Wins the Buy Box, creeps the price up while you hold it, steps back the moment you lose it.
- Knows when not to cut. When Amazon is already rotating the Buy Box between sellers at the same price, it holds instead of starting a race to the bottom.
- Your floor, from your real cost. Never below the highest of your minimum ROI, profit and price, worked out from the landed cost of the units you hold.
- Fast, and explained. Reacts to a competitor within seconds, checks every listing every 15 minutes as a backstop, and logs the reason for each move in plain English.
- Guardrails. Daily limits on how far and how often a price moves, a strategy per product, and one-click undo.

FAQ
Common questions
How does the free trial work? Do I need a card?
14 days of full access, and no card is needed to start. On day 15 we ask for one if you want to keep going; nothing is charged before then, and if you don't add one you simply aren't billed. To keep email sending fair during the trial, outreach is capped at 50 sends, enough to run a real test campaign on a small brand list.
What do I need to connect?
For gating and Deal Check: your Amazon Seller Central account, connected through the official SP-API. That's it.
For per-ASIN vetting: a market-data API key (most serious sellers already have one).
For outreach: your Gmail, plus an Apollo account for contact enrichment (the free tier works to start). You bring your own keys, so that budget is yours, not bundled at our markup.
Is the Amazon integration official?
Yes, through Amazon's official Selling Partner API. Connect once via OAuth and Opero3P syncs your fees, inventory and listing data every day. Refresh any ASIN on demand, and disconnect in one click. Refresh tokens are encrypted at rest.
Is there a discount?
If you found Opero3P through a seller group or community, your group owner has a code that gives you $59/month instead of $79, for as long as you stay subscribed. Everyone else can use our launch code LAUNCH59 for $59/month for your first 3 months, then the standard $79/month (sign up by December 31, 2026). Either way, the price you sign up at is locked for life: it never goes up for you.
How does the repricer work?
Turn it on per product and pick a strategy, or set one across many products at once. It reacts to competitor price changes within seconds of Amazon's offer alerts, checks every listing every 15 minutes as a backstop, and never prices below your floor: the highest of your minimum ROI, minimum profit and minimum price, worked out from the average landed cost of the units you actually hold. Daily limits cap how far and how often a price can move, every change is logged with the reason, and any change can be undone in one click. More about the repricer.
What's Bob for Chrome?
A Chrome extension that opens a panel on any Amazon product page. Free: whether you can sell it (checked on your own Amazon account), plus fees and profit for your cost, up to 30 lookups a day with a free Opero3P account. Included with Opero3P (and your 14-day trial): unlimited lookups, what you paid last time, market data, Bob's take, and saving a lead or creating a purchase without leaving the page.
Is my data safe? What about the bank feeds?
Your data is stored in an encrypted cloud database (Supabase); only you have access via your sign-in. Gmail tokens and API keys are encrypted at rest. Bank and card accounts connect through Plaid with read-only access: Opero3P can never move money, only the workspace owner can connect accounts or see bank lines, and disconnecting deletes the connection. Prefer not to connect? Import statements as CSV instead. You can export everything and delete everything at any time.
Does Opero3P work with Claude?
Yes. Opero3P has its own Claude connector (an MCP server). Add it in Claude under Settings → Connectors and ask about your real numbers: profit, stock, the repricer, reimbursements, outreach. It is read-only unless you allow changes, and every change waits for your yes. More about the Claude connector.
Can Opero3P help me find wholesale suppliers?
Yes. The Wholesale Finder skill (included, runs in Claude) finds brands that really sell through resellers, the distributors near you or brand programs nationwide that will open an account, rates how easy each one is, and saves them in Opero3P with the application link. You apply yourself. More about Wholesale Finder.
Does Opero3P find FBA reimbursements?
Yes. It checks every day for units Amazon lost or damaged, refunds with no return, and shipments received short, writes the case text, and keeps the complete Amazon reports ready for a deep audit. You keep 100% of what you recover. More about reimbursements.
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.
Connecting your accounts
How Opero3P uses your Google account
Opero3P is an operations platform for Amazon sellers who source inventory through online arbitrage and from brands and distributors. Opening a wholesale account means emailing those brands, so Opero3P can optionally connect to your Gmail account and run that outreach from your own address, and it can read the Google Sheets you keep your leads or purchases in. Connecting Google is optional — everything else in Opero3P works without it.
What we request, and why
- Send email on your behalf (gmail.send) — to send the outreach emails you have set up, from your own mailbox, only to brand contacts you have added to a campaign. You control the message, the recipient list, the daily send limit and the sending window. We never email an address you have not added.
- Your name and email address (userinfo.email, userinfo.profile) — to identify your account when you sign in with Google.
- Read the Google Sheets you add (spreadsheets.readonly) — only if the workspace owner connects Google Sheets, to import leads or purchases from the specific sheets whose links you add. Opero3P never writes to your sheets and never opens your other files.
How replies reach Opero3P
Opero3P does not read your mailbox. Each outreach email carries its own reply address on reply.opero3p.com, so when a brand answers, the reply comes straight to Opero3P, the brand is marked as replied, and its follow-ups stop. Optionally, you can add a Gmail filter that forwards bounce notices only, so campaigns stop emailing addresses that no longer work. You create that filter yourself and can remove it any time.
Accounts connected before September 20, 2026 also granted read access (gmail.readonly), used only to detect replies to Opero3P’s own outreach. That access was retired on October 10, 2026; reconnected accounts are send-only.
We never sell your Google data, never share it with third parties, and never use it to train AI models. You can disconnect Gmail or Google Sheets at any time in Settings, or revoke access from your Google Account permissions page.
See what you can sell, and what you really make.
Connect your account, drop in a list, and you'll have your own ungated-brands list before the coffee's cold. Fourteen days to see if Opero3P belongs in your stack.
