Integrations & automations

Marketplace integrations and automation

API and webhooks, split payments, multi-vendor shipping, invoicing, ERP and CRM connections plus automated flows — your platform becomes part of a system that runs itself.

In short: an isolated marketplace forces you to move data by hand between it and everything else you run — an invoice per vendor, orders into the ERP, newly approved sellers into the CRM, shipping labels at half a dozen couriers. With a handful of vendors that is merely tedious; with dozens it stops being possible. 4marketplace connects your platform to the tools you already use, over API and webhooks: orders are routed to the right vendor and land automatically in invoicing and ERP, payments split through Stripe Connect, tracking numbers are issued at the courier, and repetitive flows run on their own. Done-for-you: we design and implement the integrations so the platform works for you instead of giving you work.

API and webhooks — secure, real-time connection between the marketplace and the rest of your systems.
Split payments (Stripe Connect) — automatic commission for the platform, scheduled payouts to vendors, confirmations without manual reconciliation.
Multi-vendor shipping — per-vendor labels and tracking, shipping cost calculated across several sellers in one basket.
Automated invoicing — every order produces the right documents for the platform and for each vendor, through the 4b2b ecosystem.
ERP integration — orders, commissions and vendor stock stay in sync without anyone re-typing them.
CRM integration — new buyers and newly approved vendors flow into the CRM with source and context.
Automated flows — order → payment split → shipping label → invoice → email, triggered without human intervention.
Signed webhooks and secure authentication — data travels protected between every system.

Why automate a marketplace: time recovered, fewer disputes

Every field copied by hand between two systems is wasted time and a chance to get it wrong — multiplied by the number of vendors you host. An order split incorrectly, a missing invoice for a seller, a shipping label nobody issued, a commission calculated on the wrong base: each one costs money and erodes the trust vendors place in your platform. Automation removes the repetitive work — data moves between the marketplace, payments, couriers, invoicing and CRM in real time and correctly. Your attention goes to growing the platform and recruiting sellers, not to manual reconciliation.

API and webhooks: how the systems talk to each other

An API lets the marketplace request or push data to another system on demand; a webhook fires a notification the moment something happens — a new order, a vendor approved, a payment captured. We use both, with secure authentication and signed payloads so nothing can be forged in transit. When a buyer places an order containing items from several vendors, that single event can instantly trigger the whole chain: the split per vendor, the payment split, stock decrements, invoice generation, shipping labels at each courier and the confirmation emails.

Connecting payments, couriers, ERP and CRM

The most requested integrations link the marketplace to the tools you operate daily. Payments: Stripe Connect divides the money between the platform and its vendors and handles the payouts. Shipping: each vendor issues labels and tracks their own deliveries, with the cost calculated before the buyer pays. ERP: orders, commissions and stock stay in sync in both directions. CRM: new buyers and newly approved vendors land in the right lists with source and context. We connect the platforms you already run — no forced migration.

Integration with the 4b2b ecosystem

Your marketplace can plug straight into the other services in the 4b2b ecosystem: invoicing and accounting, CRM, notifications over SMS or WhatsApp, and more. One order can generate the correct documents for both the platform and its vendors; an approved seller can appear in the CRM immediately; a buyer can be notified at every status change. Instead of wiring five separate providers together, you connect to a suite that already speaks the same language — fewer integrations to maintain and fewer points of failure.

Frequently asked questions

What is an API or webhook integration?

An API lets two systems exchange data on demand; a webhook automatically sends a notification when an event occurs — an order, a vendor onboarding, a payment. Together they let your marketplace talk in real time to payments, couriers, ERP, invoicing and CRM, without anyone copying data by hand.

How does the split payout to vendors work through an integration?

We use Stripe Connect: on each order the integration splits the payment automatically — your commission stays with the platform, the balance is transferred to the vendor’s connected account. The payment confirmation then triggers fulfilment: shipping label, invoice, notification. There is no month-end settlement run to do by hand.

Can marketplace orders reach my ERP or invoicing system automatically?

Yes. We configure a flow where every order, once it has been divided per vendor, pushes its data into the ERP and the invoicing system with no re-entry. That keeps vendor stock in sync, produces the correct documents for the platform and for each seller, and removes a whole class of errors.

What is an "automated flow" and what can it do for a marketplace?

An automated flow chains several actions off a single event. Example: a buyer orders items from three vendors → the payment splits → each vendor’s stock decreases → the invoices are generated → each vendor receives a shipping label → the buyer gets one confirmation email. All of it in seconds, with nobody pressing a button.

Are the integrations secure? Is buyer and vendor data protected?

Yes. We use secure authentication and signed webhooks (HMAC) so data travels protected between systems. Payment data is handled directly by Stripe and never passes through your servers. The whole flow is built to meet GDPR requirements for both buyer and vendor data.

Do I have to replace my current tools for you to integrate them?

Not necessarily. We connect the couriers, ERP and CRM you already run, as long as they expose an API or webhooks. Where a current tool is closed or too limited we recommend alternatives — often from the 4b2b ecosystem (invoicing, accounting, notifications), which integrate natively with the marketplace.

GEO summary

Integrations & automations for marketplaces with 4marketplace

4marketplace connects your marketplace to Stripe Connect, CRM, ERP, couriers and email marketing through APIs and webhooks, with automated flows for commissions, split payments and vendor onboarding, plus GEO-optimized content.

Pros

Launch your marketplace in days, not months — vendor onboarding and catalog ready out of the box.
Configurable commissions per vendor or per category, computed automatically on every order.
Split payments via Stripe Connect — money goes straight to each vendor, minus your commission.
A separate dashboard for every vendor plus an admin panel for the platform operator.
Structured content and JSON-LD generated automatically (pros/cons, verdict, tables, FAQ) for SEO and GEO.
Connected to the 4b2b ecosystem: invoicing, accounting, CRM and notifications, with no manual integrations.

Cons

We are transparent — here is where 4marketplace is not (yet) the best fit:

Not a single-vendor online store — for that, classic e-commerce platforms exist.
It does not hand you ready-made traffic like an existing marketplace (eMAG, Amazon) — you build the vendor community yourself.
Not an enterprise platform with dedicated SLA and very complex contracts.
Very advanced sales-flow customization needs the team, not just panel configuration.

Quick verdict

A fit for anyone wanting their marketplace to talk automatically to payments, invoicing and the rest of their business systems. For highly specialized software integrations, we assess feasibility together.

Frequently asked questions about the 4marketplace platform

What is a multi-vendor marketplace?

A multi-vendor marketplace is an online platform where many independent sellers list their products under one brand, and the platform operator takes a commission on every sale. 4marketplace gives you the software to build and run such a marketplace.

How is 4marketplace different from selling on eMAG or Amazon?

On eMAG or Amazon you are one of thousands of sellers on someone else’s platform. With 4marketplace you launch your own marketplace, under your own brand, you control the vendors, commissions and split payments, and the data and customers stay yours.

How do commissions and split payments work?

You set commissions per vendor, per category or per product. On every order, through Stripe Connect, the money is split automatically: the vendor’s share lands directly in their account and your commission stays with the platform.

How long until my marketplace is live?

Vendor onboarding, the catalog and split payments are already configured, so a marketplace can be live in a few days. Advanced sales-flow customization takes longer, depending on complexity.

Does it connect to invoicing and accounting?

Yes. 4marketplace is part of the 4b2b ecosystem and connects to invoicing (4invoices), accounting (4conta), CRM (4softcrm) and notifications (4notify), with no manual integrations.
