Built for Marketplace businesses

Sync every message.
Protect every sale.

When employees delete Facebook Marketplace chats to contact buyers privately, you lose visibility and revenue. FBM Multi Messenger syncs every conversation to your secure central server in real time.

Multi-account Scaled by subscription

Why it exists

Visibility lost. Or visibility locked in.

Marketplace sellers lose deals when chats disappear from staff devices. Central sync keeps every conversation accountable.

Without FBM Multi Messenger

Staff control the inbox. Owners find out too late.

Employees delete messages and contact buyers privately
No shared history across accounts or devices
Missed inquiries and untracked sales
No audit trail when revenue disappears

With FBM Multi Messenger

Every Marketplace conversation lands on your server first.

Real-time sync of text, media, and voice messages
Owner-level visibility across all connected accounts
Employees cannot erase the central record
Full accountability for team conversations

Security & trust

Built for operators who worry about Facebook credentials — on purpose

Connecting Marketplace accounts is a serious decision. Here is how FBM Multi Messenger handles safety and accountability.

Encrypted transport

API traffic runs over HTTPS so credentials and message payloads are protected in transit between clients, extension, and server.

Central audit trail

Synced conversations live on your secured backend. Staff cannot erase the owner’s record by deleting chats on a phone.

Scoped API keys

Extension access uses API keys you generate in-app. Rotate or revoke keys when a device or operator changes.

Operational reliability

Failed sync requests are queued and retried. The Chrome extension and app keep Marketplace sessions connected while you work.

Direct answer: We designed this for business owners who need oversight, not for casual scraping. Treat Facebook credentials like production secrets, and limit who can generate API keys or add accounts.

Social proof

Operators who needed the paper trail

Specific outcomes from multi-account Marketplace teams — not generic praise.

“As a reseller managing 12 accounts, I finally know what my team is telling buyers. Deleted chats on phones no longer mean deleted history for me.”

Daniel R. Furniture reseller · 12 Marketplace accounts

“We caught a pattern of staff steering high-intent buyers off-platform. The sync made those conversations visible the same day.”

Priya S. Electronics agency · multi-city team

“Multi-account chaos was our default. One inbox, proxies per account, and canned replies cut response inconsistency overnight.”

Marcus L. Marketplace operations lead

“Payment verification took a few hours and then we were live. The extension + API key setup was clearer than I expected for a tool this serious.”

Helena K. Independent reseller · expanding to 6 accounts

FAQ

Questions Marketplace sellers actually ask

Straight answers on safety, limits, verification, and what you need installed.

Treat credentials like production secrets. Traffic uses HTTPS, and extension access is gated by API keys you control. We built this for business oversight — limit who can generate keys and who can add accounts.

New Facebook account registrations are blocked once your subscription’s MaxLimit is reached. Upgrade your plan from the app’s packages screen (or contact us for a higher ceiling) before connecting additional accounts.

After you submit payment proof, our team reviews it during office hours. Most activations complete within 4–5 hours. You will be notified once the subscription is approved.

Yes for a full setup. The Chrome extension captures Marketplace activity from Facebook using your API key, and the mobile app is where you read, reply, and administer accounts.

A dedicated desktop client is in active development. Today you can already use the mobile app on Android, iOS, Windows, and Mac.

We recommend clear internal policy: owners sync Marketplace communications for business continuity and accountability. The product preserves the central record; how you communicate that policy to staff is up to your operation.

Subscriptions are billed according to your selected plan and account limit. For cancellations, refunds, or billing disputes, contact support through the form below and include your account email — we handle these case by case.
