Light vs SAP

Why finance teams choose Light over SAP

SAP is the deepest ERP ever built, and that depth is priced in years: S/4HANA programmes measured in fiscal cycles, steering committees, and a change process that routes through a system integrator. For a multinational running complex manufacturing on 40 years of customization, that trade can still make sense. For a modern multi-entity company, the depth arrives as weight.

Light gives the multi-entity company what it actually came for: one AI-native ledger across countries and currencies, agents that run the daily work, and a close that happens continuously instead of at quarter speed. The evaluation question is not whether SAP can do it, it usually can, but what it costs in time, licences and people to make it do it.

Implementation: weeks, not programmes

S/4HANA migrations are 12 to 24+ month programmes with SI day rates to match. Light implementations run in weeks with a dedicated team and account manager included, and reconfiguration afterwards is done by the finance team in-product, not through transport cycles.

Architecture: one platform instead of module seams

SAP's finance estate spans modules and acquisitions: the GL in S/4, spend in Concur, billing in BRIM, analytics in SAC, each licensed and integrated separately. An agent cannot own a workflow that crosses licensing seams. On Light, AP, AR, cards, expenses, procurement, consolidation and reporting are one product on one ledger, which is precisely what lets agents run procure-to-pay and record-to-report end to end.

Cards, AP and global payments

SAP handles payments through bank files and treasury configuration; spend lives in Concur. Light issues cards natively, captures receipts in Slack and Teams, and executes vendor payments on local rails in 80+ countries directly from the ledger, with FX handled at the ledger level.

Joule vs agents that post

Joule is a copilot: it answers, drafts and navigates, and SAP's agentic capability is roadmap. Light's agents are in production: they code, match, reconcile, chase and post inside approval thresholds, with every action logged. On a batch architecture, promoting a copilot into an agent is an architecture migration; on Light it is how the platform already works.

Cost of ownership

SAP's cost is the programme: licences by module, SI implementation, admin teams, and change requests billed by the day. Light is one platform, implemented in weeks, operated by the finance team, with the sub-ledgers included rather than licensed separately.

Frequently asked questions

Is Light a good alternative to SAP?

For multi-entity companies from tens of millions to low billions in revenue, yes: Light delivers the global, multi-currency consolidation SAP is bought for, with agents running the work and none of the programme overhead. For the largest enterprises with deeply customized SAP estates, the switching calculus is harder; see the full landscape comparison.

How long does migrating from SAP to Light take?

Weeks, not quarters. A dedicated Light implementation team moves the chart of accounts, historical data and open items, and the finance team runs the platform directly from day one.

Does Light replace Concur and the SAP add-ons too?

Yes. Expenses, cards, AP execution and procurement are native to Light's ledger, so the Concur and BRIM tier of separately licensed products has no equivalent bill.

Can Light handle global compliance like SAP?

Light runs multi-entity, multi-currency accounting with local payment rails and tax logic across 80+ countries, holds SOC 1 Type 2 and SOC 2 Type 2 reports, and customers with $500M ARR have completed audits on it.
