Base / BaseLinker alternative

Build an order system around your fulfilment rules.

Build an owned order-management workspace when standard ecommerce flows no longer fit. Open Mercato brings customer, catalog, order and shipment records together as the foundation for your custom operation.

Compare order-volume costs, custom rules and connector coverage.

Your order volume changes the software bill

Base combines subscription and order-volume pricing, with a separate Enterprise offer. Compare your actual account costs with the implementation, hosting and maintenance of an owned application.

The exceptions become the daily process

B2B approvals, custom fulfilment rules and unusual ERP handoffs need more than another manual step. Implement the rules around your own order and customer data in Open Mercato.

You cannot afford to lose a working connector

Base has a large ready-made integration catalog. List every marketplace, store, carrier and ERP flow before a migration. Open Mercato integrations are explicitly assessed and built for the project.

Build on the operational records your team needs.

Customer and order context

Connect people and companies with sales documents, addresses and activity history.

Products, variants and pricing

Use catalog and sales-channel modules as the basis for your product and pricing model.

Orders, payments and shipments

Work with order records, sales adjustments, payments and shipment information in the sales modules.

Your fulfilment logic

Implement approvals, routing and ERP exchanges with workflows and APIs. Channel synchronization, labels and provider connections are scoped integration work.

Feature by feature

Order essentials, with control over the rules behind them.

Compare the operational foundation and the integration work required. Base has a ready-made connector ecosystem; Open Mercato is built for a scoped custom implementation.

This compares order-management scope, not full ecommerce feature parity. Stock synchronization, marketplace listings, carrier labels, invoicing and country-specific requirements need separate validation. Open Mercato hosting, integrations and maintenance are paid delivery/operating work.

The MDM NT case study describes a custom shipping implementation connected to business systems. It illustrates the delivery approach; it is not a claim that every Base connector is available out of the box.

Migrate the order flow without breaking fulfilment.

  1. Inventory the working connections

    List marketplaces, stores, carriers, ERP systems, warehouses, currencies and every automatic action. Identify which connections can stay during a phased rollout.

  2. Map the operational data

    Preserve SKU and offer identifiers, order statuses, addresses, payments and shipment references. Assign the system of record for stock and prices.

  3. Pilot one channel end to end

    Test order intake, updates, stock behavior, cancellations, payment reconciliation, labels and tracking. Include retries, duplicate prevention and failure alerts.

  4. Reconcile and switch carefully

    Set a data freeze and final synchronization plan, reconcile open orders, train operators and retain a tested rollback path.

Questions before you take the next step.

Is Open Mercato a drop-in BaseLinker replacement?

No. Base provides a large catalog of ready-made ecommerce integrations. Open Mercato is a custom application foundation. The required marketplace, carrier and ERP connections must be assessed and implemented before switching.

Does Open Mercato charge per order?

The MIT-licensed core has no per-order licence fee. Hosting, implementation, maintenance, support and external-provider usage still contribute to total cost.

Can we keep Base for marketplace connectivity?

A hybrid architecture can be scoped with Base handling selected channels and Open Mercato owning customer or operational processes. Define record ownership, synchronization and error handling before implementing it.

When is this a good fit?

When a distinctive operational workflow, code ownership or long-term application control justifies a custom implementation. A standard connector-led shop may be better served by a ready-made ecommerce platform.

Bring the order exceptions your current setup cannot handle cleanly.

Start with your channels, monthly order range, ERP and fulfilment rules. Scope a practical pilot before committing to a full migration.
