AMG vs Rillet: multi-entity finance & applied AI, two honest fits.
Rillet is a strong AI-native ERP built primarily for venture-backed multi-entity SaaS finance teams. It is a serious product, well-designed, and the right answer for the buyer it was built for. AMG builds custom multi-entity finance for the SMBs that do not fit that mold — real estate operators, federal contractors, emerging fund managers, multi-LLC owners. Different buyers, sometimes overlapping, sometimes coexisting on the same stack.
What Rillet genuinely does well
Rillet has built a credible AI-native ERP. We are not going to pretend otherwise. These are the categories where Rillet is a defensible — often the best — answer for the buyer profile they target.
AI-native general ledger
Rillet's GL is built around AI from the ground up — categorization, anomaly surfacing, and continuous close are baked into the platform rather than bolted on. For a SaaS finance team running monthly close, the platform feels modern.
Automated revenue recognition (ASC 606)
Rev rec is genuinely hard for multi-entity SaaS companies with deferred revenue, contract modifications, and milestone billing. Rillet's automated rev rec engine is one of the strongest in the AI-native ERP category.
Audit-ready multi-entity close
The consolidation engine, the elimination entries, the audit trail, and the close-cycle automation are built for the auditor conversation. For venture-backed companies preparing for a 409A, a board audit, or due diligence on a round, this is non-trivially valuable.
SaaS-finance workflow assumptions
Rillet's product shape — chart of accounts, subscription billing integration, ARR/MRR reporting — assumes a SaaS operating model. For software companies, that is exactly what you want. The workflow does not need to be rebuilt.
Where Rillet's target does not apply
Rillet is opinionated. That is a feature for the buyer they were built for, and a mismatch for buyers who do not share that profile. The mismatch is not Rillet's fault — it is what happens when a productized platform meets buyers it was not designed for.
You are not a venture-backed SaaS company
Rillet's product shape — the GL, the chart of accounts assumptions, the rev rec automation, the board-reporting templates — is built around SaaS finance. Real estate investors with one LLC per property, federal contractors with operating + leasing vehicles, and emerging fund managers do not have a SaaS-finance shape. The product asks you to bend your operations to fit, instead of the other way around.
You need vertical-specific workflows
Lease lifecycle. Per-property P&L. NAV calculations. Capital call processing. Side-letter term tracking. DCAA-style time. SAM.gov screening. BOI per entity. Credit portfolio across personal and business cards. None of these are SaaS-ERP problems. They are vertical-specific operational problems that need vertical-specific tooling.
Your stack is broader than the ERP
SMB multi-entity operators rarely have an ERP problem. They have an everything problem — banking, credit cards, document intelligence, compliance calendars, CRM, intake routing, automation flows. A productized ERP solves one of those well. AMG engagements typically span several of them, integrated.
You want a built-around-you system, not a fit-to-platform
Rillet is a SaaS product. The roadmap is Rillet's roadmap. Customization is bounded. For operators with unusual entity structures, unusual workflows, or unusual data sources, "wait for the feature" is not always a viable answer. AMG builds around your structure.
Your buyer is the owner, not a CFO/Controller
Rillet's product is sized and priced for finance teams with a dedicated CFO or Controller. Many AMG clients are the owner-operator doing their own books on Saturday mornings. The buyer profile is different and the engagement shape is different.
You want fixed-scope, not subscription
Some operators prefer a fixed-scope project with a defined outcome and a finite cost over an ongoing subscription. AMG is built that way. Rillet is built as a productized subscription. Neither is wrong — they fit different buyers.

How AMG and Rillet can work alongside each other
For venture-backed multi-entity SaaS companies that already run Rillet, AMG often plays a complementary role rather than a replacement one. Rillet handles the ERP — GL, consolidation, rev rec, close. AMG handles operational tooling around it that does not belong inside an ERP.
Examples we have seen or built: document intelligence over thousands of customer contracts, AI-augmented CRM intake that feeds Rillet customer records, AP automation for vendor invoices with extraction and matching, custom dashboards for board reports pulling from Rillet plus other sources, and licensed IP components that ship inside the company's own product (e.g. a portfolio engine, a reconciliation engine, a personal finance component).
We do not sell against Rillet for the buyer Rillet was built for. We build alongside it.
Common coexistence patterns
- Rillet for GL + AMG for document intel
- Rillet for rev rec + AMG for AP automation
- Rillet for close + AMG for board reporting tooling
- Rillet for consolidation + AMG for vertical workflows (PM, GovCon, etc.)
- Rillet for finance + AMG IP licensed into company's own product

Common questions about AMG vs Rillet
Is AMG a Rillet competitor?
Only for a specific kind of buyer. Rillet is a productized AI-native ERP built primarily for venture-backed multi-entity SaaS finance teams. AMG builds custom multi-entity finance for SMBs that do not fit that mold — real estate operators, federal contractors, emerging fund managers, multi-LLC owners. Different buyers. Some overlap in the middle.
What does Rillet do well?
Rillet is genuinely strong at AI-native general ledger, multi-entity consolidation, automated revenue recognition (ASC 606), and audit-ready close for venture-backed SaaS companies. The product is well-designed and the AI components are real. For a Series A through C software company that needs to professionalize their finance stack, Rillet is a serious option.
Where does Rillet's target customer not fit?
Rillet's product shape is opinionated for software businesses. Real estate operators, federal contractors, emerging fund managers, and multi-LLC personal-finance-integrated operators do not have the same workflow Rillet's product is built around. They need vertical-specific automations (lease lifecycle, NAV, capital calls, BOI tracking, credit portfolio management) that a SaaS-focused ERP does not prioritize.
Can AMG and Rillet coexist?
Yes. A venture-backed multi-entity SaaS company on Rillet for the core ERP, with AMG-built custom layers on top for document intelligence, vertical workflows, AI-augmented CRM intake, or licensed IP components. Rillet handles the GL; AMG handles operational tooling around it.
Why would an SMB choose AMG over Rillet?
Three common reasons. First, the operator is not in a vertical Rillet's product is shaped for. Second, the engagement is operationally broader than a GL — credit portfolio, document vault, compliance calendars, integrations to non-SaaS systems. Third, the operator wants something built around their specific structure rather than fitting their structure to a productized platform.
What about pricing?
Rillet pricing is not published publicly but third-party data points suggest it lands in the SaaS ERP band — typically several thousand dollars per month for the entry tier, scaling with entity count and modules. AMG engagements are fixed-scope project pricing — low-five-figure starter builds, mid-five to low-six-figure standard engagements, six-figure-and-up strategic partnerships. Different models, different fit profiles.
