If you are comparing Modulus365 vs Extensiv (Skubana), you are probably looking for better control over multichannel inventory, ecommerce orders, warehouse fulfilment, marketplace operations, 3PL activity, carrier despatch, B2B customers or Sage-connected operations.
Both platforms are relevant to stock-holding businesses, but they are built around different operational priorities.
Extensiv Order Manager, formerly Skubana, is best known as a multichannel inventory and order management platform for ecommerce brands. It helps businesses manage inventory across sales channels, warehouses, marketplaces, 3PLs and connected fulfilment routes.
Modulus365 is a fulfilment operations platform. It combines order management, warehouse management, inventory visibility, barcode scanning, carrier integration, B2B ordering, EDI, 3PL connectivity and fulfilment reporting, while working alongside Sage and other finance or ERP systems.
This comparison explains the practical difference between Modulus365 and Extensiv/Skubana, where each may fit, and what to consider before choosing a multichannel inventory platform or a Sage-connected OMS and WMS fulfilment layer.

The main difference is operational emphasis.
Extensiv Order Manager is especially strong where the business needs multichannel inventory and ecommerce order management across online stores, marketplaces, warehouses and 3PLs.
Modulus365 is more focused on being a fulfilment operations layer around Sage or another finance/ERP system. It combines OMS and WMS capability with carrier integration, B2B ordering, EDI, 3PL connectivity, inventory visibility and operational reporting.
That distinction matters because some businesses mainly need better ecommerce inventory control across channels, while others need to connect order management, warehouse operations, carriers, B2B customers, EDI, 3PLs and Sage into one controlled fulfilment flow.
Extensiv may be a good fit if your main requirement is multichannel inventory management and ecommerce order control.
For example, Extensiv may suit businesses that need:
If your biggest challenge is controlling inventory and orders across multiple ecommerce and marketplace channels, Extensiv should be considered.
Modulus365 may be a better fit if your business needs practical fulfilment control, warehouse execution and Sage-connected operations in one focused platform.
For example, Modulus365 is likely to be a stronger fit if you need:
In simple terms, Extensiv may suit a business looking for multichannel inventory and ecommerce order management. Modulus365 suits businesses that want practical OMS, WMS, carrier, B2B, EDI and Sage-connected fulfilment operations in one layer.
| Requirement | What to Consider | Likely Better Fit |
|---|---|---|
| Multichannel inventory management | You need inventory visibility and allocation across ecommerce, marketplaces and fulfilment locations | Extensiv |
| Marketplace order control | You sell heavily through marketplaces and need centralised order and stock visibility | Extensiv |
| Keep Sage but improve fulfilment | You want finance to stay in Sage while operations work in a fulfilment layer | Modulus365 |
| Warehouse scanning and execution | You need barcode-driven picking, packing, despatch and warehouse control | Modulus365 |
| Sage 50, Sage 200 or Sage Intacct fulfilment | You need fulfilment workflows around Sage finance or ERP | Modulus365 |

| B2B portal with customer pricing | You need customer-specific online ordering connected to fulfilment | Modulus365 |
| Wholesale, B2B and EDI fulfilment | You need account-specific rules, EDI, ASN and despatch confirmation | Modulus365 |
| 3PL and distributed fulfilment visibility | You need fulfilment visibility across warehouses, partners or external locations | Extensiv or Modulus365, depending on Sage and B2B requirements |
| Practical pick, pack and carrier despatch | You need warehouse teams to scan, pack, label and despatch orders efficiently | Modulus365 |
A multichannel inventory platform and a fulfilment operations layer are closely connected, but they are not always the same thing.
A multichannel inventory platform focuses on stock visibility, channel allocation, sales channel connectivity, warehouse stock, reorder planning, bundles, kits and order routing across ecommerce and marketplace operations.
A fulfilment operations layer focuses on making customer orders flow properly: order capture, allocation, release, warehouse picking, packing, carrier labels, despatch confirmation, inventory status, returns, exceptions, customer service visibility and ERP updates.
Extensiv is positioned strongly around multichannel inventory and ecommerce order management.
Modulus365 is positioned around practical fulfilment execution, with OMS and WMS capability combined in one operational layer around Sage or another finance/ERP system.
The right choice depends on whether your biggest problem is multichannel inventory control, or the broader order-to-despatch process across Sage, sales channels, B2B customers, carriers, 3PLs and trading partners.
If your business currently uses Sage, this comparison becomes especially important.
Many Sage businesses do not only need inventory synchronisation. They need better operational fulfilment around Sage.
Common Sage fulfilment challenges include:
Modulus365 is designed to solve these issues without forcing the business to replace Sage as the finance or ERP system.
Modulus365 is particularly relevant for businesses that use Sage 50, Sage 200 or Sage Intacct.
For Sage 50 and Sage 200 businesses, Modulus365 can add the order management, warehouse, carrier and fulfilment workflows that sit around the accounting or ERP system.
For Sage Intacct businesses, Modulus365 can provide the operational layer that product, wholesale, retail and ecommerce businesses often need alongside a finance-first platform.
This matters if your business expects to move from Sage 200 to Sage Intacct in the future. The fulfilment platform should not become a barrier to that change.

Extensiv may be relevant if your business is reviewing multichannel inventory management, ecommerce order routing, marketplace fulfilment and 3PL-connected order operations.
If the goal is to keep Sage and improve operational fulfilment around it, Modulus365 is likely to be the more natural fit.
The key question is not only whether inventory can sync across channels. The question is whether orders, warehouse execution, carriers, customer service, B2B rules, EDI, returns and Sage updates are all connected in the fulfilment process.
Before comparing features, ask this architecture question:
Are we trying to improve multichannel inventory management, or are we trying to improve the full order-to-despatch operation around Sage and our sales channels?
If you are solving inventory visibility, channel allocation, ecommerce order routing and marketplace operations, Extensiv/Skubana may be relevant.
If you are improving fulfilment around Sage or another ERP, Modulus365 is built for that role.
Order management is where Extensiv and Modulus365 overlap.
Extensiv connects sales orders with inventory, ecommerce channels, warehouses, 3PLs and routing rules. This is useful for businesses that need multichannel ecommerce order control across multiple fulfilment routes.
Modulus365 is built around order-to-despatch execution. Its order management focus is specifically tied to practical fulfilment operations: order capture, allocation, release, warehouse execution, carrier despatch, returns and operational visibility.
For growing businesses, order problems often begin before the warehouse starts picking.
Common issues include:
Modulus365 is designed around this fulfilment flow. It helps manage order capture, allocation, release, picking, packing, despatch and status visibility.
Both Extensiv and Modulus365 are relevant to warehouse and fulfilment operations, but they approach the problem from different starting points.
Extensiv supports fulfilment workflows as part of a multichannel inventory and order management platform.
Modulus365 includes warehouse execution as a core part of the platform.
Typical warehouse requirements supported by Modulus365 include:
This makes Modulus365 especially relevant when the business needs OMS and WMS capability together, rather than inventory and order management with warehouse workflows around it.
Inventory visibility is central to both platforms, but the operating emphasis differs.
Extensiv helps businesses manage inventory across sales channels, warehouses, 3PLs, suppliers and ecommerce platforms. This is useful where channel allocation, bundles, kits, reorder planning and marketplace stock control are key priorities.
Modulus365 focuses on operational inventory visibility across fulfilment channels, warehouses, 3PLs and customer promises, while keeping finance and core accounting in Sage or the existing ERP.
Growing fulfilment operations need to know:
If the main requirement is multichannel inventory visibility, order routing and channel stock control, Extensiv/Skubana may be a strong fit.
If the main requirement is operational stock visibility tied to warehouse execution, Sage updates, B2B customers, EDI flows, carrier rules and fulfilment reporting, Modulus365 is likely to be the stronger fit.
Extensiv is highly relevant for businesses that need inventory and order connectivity across ecommerce and marketplace channels.
Typical ecommerce and marketplace requirements include:
Modulus365 also supports ecommerce and marketplace fulfilment, but the wider value appears when ecommerce is only one part of the operation.
For example, Modulus365 is especially relevant when ecommerce sits alongside:
If ecommerce and marketplace inventory control is the main requirement, Extensiv may be a good fit.
If ecommerce is part of a wider B2B, wholesale, EDI, Sage and warehouse operation, Modulus365 may be the stronger fit.
Extensiv is especially relevant where a business needs to manage bundles, kits, parent-child products, component availability and marketplace SKU complexity.
This can be important for ecommerce businesses that sell product bundles across multiple channels and need to understand how bundle availability is calculated from component stock.
Modulus365 can support fulfilment requirements where SKU complexity affects picking, packing, stock visibility and customer promises, but its broader strength is connecting SKU handling to the operational fulfilment process.
Useful questions to ask include:
If bundle visibility across ecommerce channels is the main requirement, Extensiv may be a strong fit.
If bundles need to connect to warehouse execution, Sage, B2B fulfilment and operational dashboards, Modulus365 should be considered.
B2B and wholesale fulfilment usually needs different rules from direct-to-consumer ecommerce.
Common requirements include:
Extensiv is relevant where the business needs multichannel inventory and order management across ecommerce, marketplaces, wholesale and fulfilment routes.
Modulus365 is especially relevant where a business wants ecommerce, wholesale, B2B and EDI fulfilment in the same operational layer, while keeping Sage or another finance platform as the system of financial record.
EDI and retail fulfilment can add a layer of complexity beyond standard ecommerce fulfilment.
Typical requirements include:
Modulus365 is particularly relevant where EDI, ASN and retail trading partner fulfilment need to sit alongside warehouse operations, Sage updates, carrier despatch and B2B order flow.
As businesses grow, fulfilment often becomes distributed.
You may need to manage:
This creates practical questions:
Extensiv is relevant where a brand needs multichannel order routing and inventory control across warehouses and 3PLs.
Modulus365 is designed for distributed fulfilment where the business needs operational visibility across warehouses, 3PLs, B2B flows, carriers and Sage-connected inventory updates.
Despatch is not just the final warehouse step. It affects customer experience, carrier cost, tracking visibility, marketplace performance and customer service workload.
Carrier decisions may depend on:
Extensiv supports shipping and return label activity as part of its multichannel fulfilment operations.
Modulus365 places carrier selection, label generation and despatch automation inside the practical warehouse fulfilment flow.
This is useful when the business wants to reduce manual carrier admin, improve despatch accuracy and give customer service better tracking visibility.
A fulfilment operation needs more than transaction processing. It needs visibility of risk.
Useful operational views include:
Modulus365 is designed to give operations teams visibility of order flow, backlog, stock issues, exceptions, despatch risk and fulfilment performance.
This matters when warehouse, customer service, finance, ecommerce and leadership teams all need a shared operational view.
Extensiv has a strong automation message around multichannel inventory, order routing, ecommerce operations, stock allocation, purchasing and fulfilment routing.
Modulus365 also supports automation, but its automation focus is wider fulfilment execution around Sage and operational control.
Examples include:
If the automation requirement is multichannel inventory management, marketplace order routing and ecommerce operations, Extensiv/Skubana may be relevant.
If the automation requirement is fulfilment execution around Sage, B2B, EDI, 3PLs and operational visibility, Modulus365 is likely to be more focused.
Before choosing between Modulus365 and Extensiv, be clear about project scope.
Ask:
If the project is mainly multichannel inventory, ecommerce order routing, marketplace operations and 3PL-connected fulfilment, Extensiv/Skubana may be relevant.
If the project is focused on improving fulfilment while keeping Sage or another finance system, Modulus365 is likely to be a more direct fit.
