The AI alternatives to ERP, compared
A new generation of platforms is replacing the ERP model with AI-native accounting. They are not interchangeable. Here is the landscape, with named vendors and honest marks, including where Light is not the obvious pick.
Two very different things get called an “AI alternative to ERP”
The first is the incumbents retrofitting AI onto systems designed decades ago: SAP, Workday, NetSuite, and Microsoft Dynamics all now ship copilots and AI features. The retrofit inherits the architecture underneath, so the batch processes, module seams, and implementation projects remain. You get faster data entry into the same retrospective system.
The second is the AI-native platforms: systems where agents doing the accounting work is the design premise, not a feature release. Light is built in this camp: agents on one ledger, rather than AI features on an old one. The differences between the two camps are architectural, which is why they decide the choice.
The questions that separate them
Four questions do most of the work. Is the platform the system of record, an actual multi-entity general ledger, or a layer that syncs into one? Are AP, cards, expenses, and procurement native, or handled through integrations to Ramp, BILL, Brex, or Expensify? Is the AI agentic, completing work inside your controls, or assistive, suggesting while humans do? And does the vendor operate globally, or is it built for a US install base with international entities as an afterthought?

The SMB ceiling: QuickBooks and Xero
QuickBooks and Xero are excellent single-entity ledgers and the wrong shape for what comes after: both run one company per file or subscription, so a second entity moves consolidation into spreadsheets and add-ons. Teams typically leave them the year international entities appear. Ocean.io replaced QuickBooks and e-conomic with Light and cut its close by 60%.
The mid-market cloud generation
Sage Intacct defined cloud accounting for the US mid-market: a strong dimensional GL with contract billing, partner-led implementations, and spend handled through marketplace tools. It cloudified the ledger without changing who does the work, which is exactly the line AI-native platforms cross.
The incumbents with AI attached
SAP, Workday, NetSuite, and Microsoft Dynamics remain the safe procurement answer, and for very large enterprises with deep customization needs they are often still the right one. Their AI is real but assistive: copilots that draft and summarize, with agentic capability on roadmaps rather than in production. The implementation model (long projects, integration marketplaces, per-module pricing) is unchanged, because the architecture underneath is.
Where Light sits
Light’s bet is that the four questions above should all have the same answer: one AI-native ledger where AP, AR, cards, expenses, procurement, consolidation, and reporting are native, so agents can run work end to end across 80+ countries. That makes Light the strongest fit for multi-entity, multi-currency companies, and honestly less differentiated for a single-entity US startup that just wants a better ledger than QuickBooks. The detailed comparisons linked above go feature by feature.
