Most ERP selection content is sponsored by one of the platforms it covers. This is not. Zanovoy is an Oracle NetSuite Alliance Partner, a SuiteWorld 2025 Alliance Partner Spotlight Award winner, and a current implementation partner for both Rillet and Campfire. We deliver all three. We also tell CFOs when none of the three is the right answer.
This guide gives you the framework working consultants actually use: the criteria that drive the decision, where each platform wins, a 12-question fit checklist, and the honest pattern we see in advisory work. Free Selection Scorecard at the end.
1. The three-platform decision in 2026
For 20 years, mid-market ERP selection was a one-platform decision. NetSuite versus Sage Intacct versus Microsoft Dynamics, and most of the time NetSuite won the moment a CFO said "subsidiary." That is over.
Three things changed it. Venture capital: Rillet has raised $108.5M from Sequoia, a16z, and ICONIQ; Campfire has raised over $100M from Accel and Ribbit. AI architecture: Rillet and Campfire were built finance-first with embedded AI for journal entries, ASC 606, flux analysis, and natural-language queries. NetSuite added these capabilities as a layer on top of an existing platform. The buyer profile shifted: AI-era SaaS companies (Mercor, Hebbia, Decagon, Replit, PostHog) decided NetSuite was the wrong tool and chose Rillet or Campfire instead.
NetSuite still serves 43,000+ customers and powered 61% of US technology IPOs since 2011. The question is no longer "NetSuite or not NetSuite." It is a real three-way decision, and the wrong choice is now expensive in both directions.
2. NetSuite, Rillet, and Campfire at a glance
Side-by-side, current as of April 2026.
3. The nine criteria that should drive your choice
Questions one through three are knockout questions. The remaining six rank the survivors.
- Business model. Product-centric (inventory, COGS) eliminates AI-native platforms. Subscription/services opens them up.
- Operational complexity. Need CRM, PSA, HCM, or commerce in the same system as the GL? Only NetSuite handles that scope.
- Entity structure. Under five entities, US-only opens Rillet. Five to fifty multi-currency opens Campfire. Over fifty favors NetSuite OneWorld.
- Compliance footprint. Regulated verticals (Life Sciences, Energy) need FDA-ready audit trails and 21 CFR Part 11 alignment that AI-native platforms have not built.
- Finance team capacity. Lean teams (one to three) benefit disproportionately from AI-native automation. Larger teams care more about platform breadth.
- Implementation timeline. Live in eight weeks rules out NetSuite. Six to nine months opens all three.
- Total cost of ownership. NetSuite first-year cost runs $150K to $750K+. Rillet and Campfire first-year cost runs $50K to $150K. The gap closes over five years.
- Audit readiness. NetSuite has the deepest audit firm familiarity. Rillet is SOC 1 Type II. Campfire serves a public company (LimaOne, NYSE) but has shorter track record.
- Integration ecosystem. NetSuite has 1,000+ certified SuiteApps. Rillet and Campfire ship native connectors to the modern finance stack (Stripe, Salesforce, Ramp, Brex, Rippling).
4. Where each platform wins and loses
NetSuite
- Wins: multi-entity operations with global consolidation; product-centric businesses (inventory, supply chain, manufacturing); regulated verticals (Life Sciences, Energy, Medical Devices); IPO trajectory (61% of US tech IPOs since 2011); CRM, PSA, and HCM in the GL system.
- Loses: simple SaaS with no inventory or PSA needs; aggressive timelines under 12 weeks; UX expectations set by Stripe and Notion; customization-heavy deployments where SuiteScript becomes technical debt.
Rillet
- Wins: SaaS or usage-based revenue with clean CRM data (ASC 606 automation from Salesforce or HubSpot is the strongest single capability); lean finance teams (one to three people); under ten entities; replacements for QuickBooks or outgrown Sage Intacct; deployments live in 4 to 6 weeks.
- Loses: any inventory, manufacturing, or field service; regulated verticals; multi-entity complexity beyond ten entities; replacements for already-customized NetSuite instances.
Campfire
- Wins: high-growth tech that has outgrown Rillet but does not need NetSuite; enterprise permissioning (1,200+ granular roles); multi-entity consolidation in 180+ currencies; audit-readiness for tech companies tracking toward an exit.
- Loses: same scope ceiling as Rillet (no inventory, no manufacturing, no CRM/HCM in the GL); product companies of any kind; pre-revenue or very early-stage startups.
5. The 12-question fit checklist
Each yes or no points toward a platform. The pattern of answers, not any single one, is the signal.
A pattern of yeses on questions 1, 4, 5, 7, and 11 is a NetSuite profile. A pattern of yeses on 2, 6, 8, and 9, with no on 1, 4, and 11, is a Rillet profile. A pattern of yeses on 2, 3, 9, and 10 is a Campfire profile. Mixed answers without a clear pattern usually mean a longer scoping conversation, not a faster decision.
6. What we recommend, and when we recommend nothing
After running this framework with mid-market and enterprise CFOs since 2016 (more than 1,000 implementations and 80+ IPOs supported), here is the pattern. Roughly half the time the right answer is NetSuite (product complexity, multi-entity scale, regulated industry, IPO clock). Roughly a third of the time it is Rillet or Campfire (SaaS or AI-era tech with a clean revenue model and an aggressive timeline). The remaining cases, our actual recommendation is to do nothing yet.
The most expensive ERP project is the one a company runs 18 months too early. If your finance team is two people, your revenue is under $5M, and your QuickBooks instance is working, the right call is often to wait, hire a controller first, and revisit in 12 months. We will say so on the first call. That "recommend nothing" posture is the reason CFOs trust the rest of our recommendations.

Frequently asked questions
What is the best ERP for a SaaS company in 2026?
For most SaaS companies under $100M ARR with a single legal entity, no inventory, and a finance team of one to three people, Rillet is the strongest fit. SaaS companies with multi-entity complexity or 50+ finance and operations users typically fit Campfire better. NetSuite remains correct for SaaS companies with significant PSA, HCM, or CRM needs in the same system, and for any SaaS company within 18 months of an IPO filing.
Can Rillet replace NetSuite?
Rillet can replace NetSuite for finance-only use cases at SaaS companies with simple operational models. It cannot replace NetSuite for product-centric businesses, regulated verticals, or companies using NetSuite's CRM, PSA, HCM, inventory, or commerce modules. Replacing a customized NetSuite instance with Rillet rarely justifies the switching cost.
What is the difference between Rillet and Campfire?
Both are AI-native finance platforms with similar scope. Rillet is narrower, faster to deploy, and CFO-led. Campfire has stronger multi-entity consolidation, 1,200+ granular permissions, and 180+ currencies. We recommend Campfire when a tech company has more enterprise complexity than Rillet handles gracefully but does not need NetSuite's operational footprint.
When should I avoid AI-native ERPs?
Avoid AI-native finance platforms if you sell, ship, or manufacture physical products; if you operate in a regulated vertical (Life Sciences, Medical Devices, Energy); if you operate more than 25 legal entities; or if you need CRM, PSA, or HCM in the same system as the GL.
How long does each ERP take to implement?
NetSuite typically takes 3 to 9 months for mid-market deployments. Rillet implementations run 4 to 6 weeks. Campfire implementations run 6 to 10 weeks. Variance comes from data quality, integration count, and CRM cleanliness.
