What each system is, in one paragraph
Rillet
ai-native ERP for SaaS finance teams
Rillet is a venture-backed, AI-native general ledger and accounting ERP built specifically for SaaS and subscription-business finance teams - roughly Series A through pre-IPO software companies (~$5M-$200M ARR). It wins on automated ASC 606 revenue recognition driven directly from CRM and billing data, native multi-entity consolidation, and AI-assisted close automation, positioned as a faster-to-implement alternative to NetSuite or Sage Intacct for companies whose operations are purely digital. It is deliberately not an operational ERP: there is no inventory, manufacturing, supply chain, or order management, and buyers keep their surrounding stack (billing, AP spend cards, payroll, planning and forecasting) as separate subscriptions. The core diligence question is not functionality within its lane - early adopters generally rate that highly - but vendor youth: the company was founded in 2021, and long-run track record, ecosystem depth, and data portability deserve explicit scrutiny.

ai-native ERP for multi-entity finance
Light is a finance platform to evaluate when multi-entity accounting, billing, spend, and reporting need to work together. Its current documentation includes subscription management and revenue recognition, an app catalog, and a KPMG partnership; older descriptions of these capabilities as absent are outdated. This review assesses public documentation, not a production implementation. A shortlist decision should depend on a demonstrated close using your entity structure, contracts, integrations, and local requirements.

Pricing
Which costs less - and what you'll actually pay
Rillet and Light sit in a similar cost tier. Typical annual software spend for Rillet is ~$25K-$35K/yr (Vendr median ~$28K), with realistic year-one totals of ~$35K-$60K all-in (est., 3-entity SaaS). Light has no public price figure we could verify, so it needs a written quote for your scope. Compare quotes on the same users, modules, and implementation scope.
| Rillet | Light | |
|---|---|---|
| Licensing model | Quote-based annual SaaS subscription priced on enabled features and complexity - entity count, transaction volume, integrations, and rev-rec complexity - explicitly not per-seat or revenue-based; implementation is a separate one-time fee. Some third-party listings describe Starter/Scale/Enterprise tiers (gating multi-entity consolidation, segregation-of-duties controls, and API access at the top tier), but the vendor publishes no tier names or prices, so treat tier structure as unverified. | Quote required. We have no verified public Light price list or representative deal benchmark in the sources reviewed September 13, 2026. |
| Entry annual cost | ~$20K/yr (Vendr-observed low; quote-based) | Undisclosed (no public data) |
| Typical annual software | ~$25K-$35K/yr (Vendr median ~$28K) | Undisclosed (no public data) |
| Implementation | Undisclosed; est. mid-4 to low-5 figures | Undisclosed (no public data) |
| Realistic year-one total | ~$35K-$60K all-in (est., 3-entity SaaS) | Undisclosed (no public data) |
| At renewal | No public renewal data exists - this is a diligence gap, not a clean record. The structural risks are young-vendor specific: early-adopter discounts resetting to list at first renewal, complexity-based repricing when entities or connectors are added mid-term, and pricing power increasing after $200M+ of funding and rapid customer growth. Before signing, ask directly: what is the contractual renewal uplift cap, what happens to promotional pricing (e.g., Mercury perk terms) at renewal, and what does adding an entity or integration cost mid-contract. Multi-year rate locks are the standard defense and the vendor's land-grab posture suggests they are gettable. | We have not established a reliable renewal benchmark. Ask for the applicable uplift terms and the price impact of adding entities, users, apps, or volume. Model a renewal using the same scope as the initial quote. |

Delivery
Implementation: what each takes to go live
| Rillet | Light | |
|---|---|---|
| Typical timeline | 4-6 weeks is the vendor-claimed and commonly reported window for a standard SaaS migration (from QuickBooks/Xero or NetSuite), versus 5-9+ months for comparable NetSuite projects; complex historical data or messy rev-rec contracts extend it. | No independently established typical duration in this review. Build the schedule from migration scope, integrations, local requirements, reconciliation, training, and a successful parallel close. |
| Who delivers it | Vendor-led, 'white-glove' - Rillet's in-house team of CPAs and ex-auditors runs migration and onboarding directly. That produces consistent quality today but concentrates delivery risk in one young company's bandwidth as its customer count grows. Protiviti announced an advisory and implementation partnership in September 2026, so a partner-led option now exists for larger programs. | Confirm which work Light, a partner, and your staff will perform in the specific proposal. Do not assume a partner announcement supplies an implementation team. |
| Watch for | Underestimating rev-rec data cleanup: automated ASC 606 is only as good as the CRM/billing contract data feeding it - dirty Salesforce or Stripe data is the most common source of timeline slip. | Selecting against generic module labels without testing the exceptions that drive the project. |
