Neptune

What Neptune is

Neptune is a low-code application platform built to run inside SAP rather than beside it. Neptune Software's home page says it puts "Business Applications, Process Orchestration and AI Agents" on top of your standard and custom SAP logic, running on ECC, S/4HANA or a hybrid landscape. It is for enterprise IT teams and SAP developers who need new apps and automated processes without standing up another database, integration layer or security model. The company's one-line pitch is: "Most low-code platforms connect to SAP from the outside. Neptune is built to work with SAP from the inside." Its FAQ describes Neptune Software as an SAP-native application development platform that teams use to build, run and manage business applications and AI agents directly on SAP ECC and SAP S/4HANA, "without middleware, replatforming, or copying business data outside SAP."

The company also calls Neptune DXP "the SAP-native Execution Platform," and argues that application development platforms help you build while an execution platform also has to run what you build, inside SAP's runtime, under SAP's security and transport lifecycle.

What you build and how

Applications. The site lists the use cases it builds for: warehouse and logistics, asset management, stock and inventory, and supplier portals. The home page aims business applications at "the operational work SAP transactions fit worst": inspections, maintenance, warehouse, procurement, production and field service, "built from proven templates on your own SAP logic" and, in the company's words, "live in days." It then walks through four use cases. Asset and plant maintenance covers preventive maintenance, work orders and field technicians on mobile apps. Warehouse operations promises "up to 30% faster inventory counting" plus better picking accuracy and goods receipt. Procurement and supplier collaboration gives suppliers and approvers one place to act on SAP procurement steps. Stock and inventory covers mobile cycle counts, transfers, goods issue and adjustments, described as "Barcode/RFID-verified, offline-capable, and synced automatically with SAP." Neptune's platform menu groups the product under "Build, connect and run," with entries for native low-code for SAP, easy API-first integration, running mobile in offline mode, building Fiori apps simply, and mastering SAP BTP services.

AI-assisted building. The home page says: "Describe the application you need and Naia Build generates it from your own SAP business objects, with low-code and pro-code control at every step." Naia is listed as Neptune's AI assistant. The pitch is "from prompt to production, never rebuilt," and the company says low-code and pro-code live in one application model, so developers can drop into code where they need to.

Data and logic. Neptune works against SAP's own business objects. The company says applications work on your standard and custom business objects, and its FAQ stresses custom SAP logic, Z-objects, modifications and workflows built up over many years. The stated benefit is "no middleware, no second security model, no duplicated logic," plus fewer copies of sensitive data to secure and one source of truth for operational processes. The page also says Neptune connects across the non-SAP systems a process touches.

Process orchestration. The home page describes multi-step processes across SAP and non-SAP systems, "with people, systems and AI agents each taking their step, governed by the SAP authorizations you already have." Its shorthand is "AI in the work, not alongside it," with AI agents embedded "where they save a step." The company calls SAP the system of record and Neptune "the System of Work" that turns what SAP manages into what people, partners and agents do.

Fiori apps. The FAQ explains that SAP Fiori is SAP's design system and that traditional Fiori development can involve SAPUI5 development, gateway configuration and extra deployment steps. Neptune says it lets teams build Fiori-compliant applications directly on SAP, cutting that overhead while keeping a consistent SAP user experience.

AI agents and guardrails. The FAQ separates generative AI, which creates text, code, images or summaries, from agentic AI, which plans steps, interacts with systems and executes tasks. Its warning is worth quoting: an AI-generated answer can be reviewed before anyone acts on it, but an agent posting a goods movement in SAP "has already changed the state of the business," so agents need the same guardrails as people, meaning the right authorizations, business rules, governance and auditability. Neptune says its applications are governed under your SAP authorizations.

Offline and devices. The FAQ answers "Can SAP apps work offline?" with "Yes. Neptune applications can work fully offline, allowing users to continue working even when there is no reliable network connection." A device can capture a stock count, an inspection or a work order offline and synchronize with SAP when the connection returns, which the FAQ ties to warehouses, plant floors, offshore environments, remote sites and service vehicles.

Clean core and S/4HANA. Another FAQ answers whether you can modernize SAP apps before migrating to S/4HANA with "Yes," and says applications built with Neptune run on both ECC and S/4HANA, so the work moves with you when the ERP core changes. The company contrasts a multi-year S/4HANA migration with "a warehouse team counting stock on paper," a problem it says you can solve now. On clean core, the FAQ says Neptune keeps custom application development separate from modifications to the SAP standard core.

Licensing, trial and customers

The site publishes no price list. It does say how licensing works: "Named-user licensing with no surprises when adoption grows." The FAQ says "Neptune offers a 30-day free trial so your team can build, test, and evaluate the platform using your own requirements," and the site also offers a demo booking. A separate community site carries its own free trial link, documentation and e-learning.

On scale, the home page claims "Trusted by 600+ enterprises building on SAP without rebuilds," and says global enterprises running mission-critical operations use it, "from Johnson & Johnson to the Norwegian Armed Forces." The FAQ lists customers including Johnson & Johnson, Vattenfall, Secil, Dussmann, Rust-Oleum, United Utilities, Safran Vectronix and the Norwegian Armed Forces. On speed, it says the timeline depends on the process, but that "Secil delivered 17 applications in three months, supporting 1,000 employees and customers." Customer stories cover Vattenfall's maintenance workflows, a warehouse system at Rust-Oleum and a digital supply chain program at Johnson & Johnson. Reviews quoted on the home page include an SAP technical lead at Zellstoff Pols AG: "Makes it very easy to prepare apps and integrate with SAP." Its industry list covers manufacturing, defense, oil, gas and energy, utilities and retail, and it publishes a video on low-code for government and public sector aimed at agencies that want to modernize processes while keeping security. The home page also addresses three audiences: business leaders who want to see a working application, CIOs and architects concerned with "Clean core, governance, security and TCO," and SAP developers promised "Templates, Naia Build and native SAP integration."

Support and learning material appears in the navigation: a support center, documentation, e-learning, an evaluation guide, professional services, a partner program, and a Neptune Experience Center. The company also publishes a whitepaper called The AI Execution Gap and a SAPinsider Spotlight Series study on AI-driven process transformation in SAP-centric enterprises, plus webinars, demos, videos and a podcast called Neptune Talks.

The home page frames its offer as three promises: native on SAP (ECC, S/4HANA, hybrid), operational SAP data with AI, and bring your custom logic. Its argument for the second is that enterprise AI becomes much more valuable when it can securely work with business-specific context and turn insight into action, which for an SAP shop means the custom logic that actually runs the business.

Who it suits, and where it pinches

Neptune suits an SAP-centric enterprise, especially one with years of custom logic and Z-objects it does not want to re-implement elsewhere, and a team that already thinks in SAP authorizations and transports. The pitch is strongest for warehouse, inventory, asset and supplier scenarios that need mobile or offline use, and for IT groups trying to modernize ahead of an S/4HANA move without rebuilding from scratch.

The caveat is the same as the strength: Neptune is built around SAP. A company with little SAP, or one that wants a general-purpose builder for forms, websites or small-team automations, is not the target reader. Named-user licensing means cost follows the number of people, so adoption planning matters. Prices are not published, so budgeting starts with the trial and a demo.
