One Platform, Three Types of Users — All Supported

Extensiv is the platform formerly known as 3PL Central, now combined with Extensiv Order Manager (formerly Skubana) into a unified fulfillment ecosystem. It's used by 3PL warehouses, the brands that rely on them, and 3PLs that handle retail-compliant fulfillment for their clients. SBSA Technology builds the integration layer for all three.

3PL Warehouses

Operators running Extensiv 3PL Warehouse Manager need standardized, repeatable EDI and API connections for every client they onboard — without custom-building a new integration each time.

Multi-Client WMS Core Reusable Templates

Brands & Suppliers

Ecommerce brands and wholesale suppliers using a 3PL on Extensiv need their ERP, sales channels, and accounting system to talk to the warehouse automatically — orders out, inventory and invoices back.

Retail-Compliant 3PLs

Four Ways to Connect with Extensiv

Extensiv supports API-based integration as its primary connectivity method, alongside EDI via AS2, SFTP, and VAN for trading partner and retail compliance scenarios. SBSA Technology handles complete setup, testing, and ongoing monitoring across all four.

AS2

Direct EDI Protocol

Encrypted, point-to-point EDI transmission via AS2 — used when retail trading partners require direct EDI connectivity alongside your Extensiv warehouse operations.

  • Protocol: AS2 over HTTPS with digital certificates
  • Standard: ANSI X12 — warehouse & retail transactions
  • Best for: High-volume retail-compliant 3PLs
  • SBSA manages: AS2 setup, certs, mapping & testing

SFTP

Secure File Transfer

Secure FTP-based document exchange for warehouse EDI files — a practical option for clients with existing SFTP infrastructure connecting into Extensiv-managed warehouses.

  • Protocol: SFTP (SSH File Transfer Protocol)
  • Standard: ANSI X12 flat files
  • Best for: Mid-volume clients & batch processing
  • SBSA manages: SFTP setup, file routing & monitoring

VAN

Value-Added Network

EDI VAN connectivity for retail trading partner compliance — required by many big-box retailers and marketplaces for 3PLs fulfilling on their behalf through Extensiv.

  • Protocol: EDI VAN — SBSA provides EDI ID
  • Best for: Retail-compliant 3PLs & smaller suppliers
  • Monitoring: 24/7 document tracking and alerts
  • SBSA manages: Full VAN setup, routing & compliance

Extensiv Integration FAQ

Common questions from brands, 3PLs, and retail-compliant operators beginning their Extensiv integration.

Extensiv is the rebranded, unified platform formerly known as 3PL Central. Extensiv 3PL Warehouse Manager is the core warehouse management system (WMS) used by thousands of 3PL operators, while Extensiv Order Manager (formerly Skubana) handles multichannel order orchestration for brands. SBSA Technology integrates with both products under the unified Extensiv ecosystem, regardless of which name your account was originally set up under.

SBSA supports the core warehouse EDI transaction set used with Extensiv, including 940 Warehouse Shipping Order, 943 Warehouse Stock Transfer Shipment, 944 Warehouse Stock Transfer Receipt, 945 Warehouse Shipping Advice, 846 Inventory Inquiry/Advice, and 947 Warehouse Inventory Adjustment Advice. For retail-compliant fulfillment, we also map 856 ASN, 855 PO Acknowledgment, 810 Invoice, and 997 Functional Acknowledgment — all fully mapped to your ERP.

Yes. SBSA Technology is an Intuit Silver Partner for both QuickBooks Online and QuickBooks Enterprise. We build direct, automated connections between Extensiv warehouse activity and your QuickBooks ledgers — syncing inventory receipts, shipments, sales invoices, and 3PL storage or fulfillment billing without manual data entry. The right QuickBooks product depends on your transaction volume and whether you need multi-entity or class-based tracking for multiple clients.

Extensiv's primary integration method is its REST API, which SBSA uses for real-time order, inventory, and shipment synchronization with your ERP and accounting systems. For retail trading partner compliance, SBSA also configures AS2, SFTP, and VAN-based EDI connections. The combination depends on whether you're integrating an ERP, an ecommerce platform, or meeting retail EDI requirements on top of your Extensiv warehouse operations.

Yes. SBSA builds bi-directional, near real-time inventory sync using the 846 Inventory Inquiry/Advice transaction and Extensiv's API, so stock levels in your ERP, Extensiv, and downstream sales channels stay aligned. This reduces oversells on marketplaces, prevents stockouts at the warehouse, and eliminates end-of-day manual reconciliation between systems.

Both. Brands shipping through a 3PL on Extensiv get automated order routing from their ERP, real-time inventory visibility, and accounting sync back to QuickBooks or another ERP. 3PLs running Extensiv for multiple clients get standardized EDI/API onboarding templates, multi-tenant inventory and order mapping, centralized monitoring across their entire client base, and consolidated billing automation into QuickBooks Online or Enterprise.
