Rillet is one of the most impressive finance platforms of this generation — an AI-native general ledger built by accountants, backed by top-tier investors, replacing NetSuite and Sage Intacct for modern finance teams. The comparison isn't about who does accounting better. It's about scope: Rillet rebuilt the finance slice of the ERP. BrioSync rebuilt the whole ERP.
AI-led implementation & migration · Live in days
If your only problem is the books, Rillet is a genuinely excellent choice. Here's what they do well — no asterisks.
Automated general ledger, AR/AP, bank reconciliation, close management and advanced revenue recognition — designed by people who have run a close themselves. Multi-entity consolidation and SaaS metrics come straight from the GL.
Ask-your-GL conversational AI and workflow agents that take real work off the accounting team. Rillet has earned its "AI-native ERP for accounting" positioning — it isn't a chatbot bolted onto a legacy ledger.
A $70M Series B co-led by Andreessen Horowitz and ICONIQ (over $100M raised in total), CPA-led implementations measured in weeks not quarters, and customers like Windsurf, Sotheby's and Kickstarter.

Rillet is finance software, deliberately and unapologetically. There is no PSA or project delivery, no service desk or customer portal, no CRM pipeline, no HR, and no source-to-pay procurement beyond accounts payable. That focus is a strength — it's why the accounting is so good.
But if you're a services or operations company, the books are maybe a fifth of your system footprint. You also run delivery projects with timesheets and margins, support tickets with SLAs, a sales pipeline, hiring and onboarding, and purchasing with approvals. Put Rillet at the centre and you still stitch four to six other products around it — a PSA, a helpdesk, a CRM, an HRIS, a procurement tool — each with its own login, its own data model, and its own sync to keep the GL honest.
You end up with a beautifully modern, AI-native island — surrounded by the same integration archipelago you were trying to escape.
BrioSync starts from the same conviction Rillet does — ERP software should be AI-native from the ground up, not a legacy suite with a copilot stapled on. We just draw the boundary differently: the whole business, not the finance slice.
One record flows from deal → project → ticket → timesheet → invoice → GL, on one system of record. The general ledger is real double-entry with live statements; procurement runs source-to-pay with budget hard-stops; delivery, service desk, CRM, HR, EPM, risk & compliance and platform & security all share the same data — 12 suites, 100+ modules. And one AI agent — chat and voice — works across every module: propose → confirm, role-scoped, fully audited. Ask it for a dashboard in a sentence; scan a supplier quote and it drafts the purchase request.
Rillet's CPA-led implementations, live in weeks, are a real achievement — legacy ERP migrations are usually measured in quarters and consultant invoices. Full credit.
BrioSync goes one step further: implementation and migration are AI-led. The agent discovers your setup, proposes the configuration, migrates the data, and explains what it did — live in days. And after go-live, change stays cheap: describe the new report, approval rule or workflow in chat and it's configured, no change-request cycle.
This is a scope comparison, not a scoreboard — within finance, Rillet is deep and excellent.

Rillet has built exceptional depth in areas like advanced revenue recognition and SaaS metrics — if those are your hardest problems, they deserve a serious look. BrioSync's finance suite is a real double-entry GL with live statements, AR/AP, collections, multi-currency and multi-entity — and it shares one system of record with delivery, procurement, CRM and HR, so the books reconcile with operations by construction rather than by integration.
You can — many companies do, and it works. The cost is carrying four to six products, their integrations, their per-seat bills, and the reconciliation between them. Every handoff (deal to project, ticket to timesheet, timesheet to invoice) becomes a sync job instead of the same row of data. BrioSync exists for the teams who'd rather that whole chain live in one system.
Fair question, and we won't pretend otherwise: Rillet's funding and customer list are real signals. BrioSync is early, working closely with founding customers. What we offer in exchange is scope no finance-only tool will ever cover, an AI-led implementation you can evaluate in days rather than a quarter, and a guided demo plus sandbox you can test before committing anything.
The noun. Rillet's "AI-native ERP" is, by their own positioning, the accounting and finance core — and it's a very good one. BrioSync's is the entire ERP: 12 suites, 100+ modules — finance, EPM, procurement, project delivery, service desk, CRM & CX, HR, risk & compliance, platform & security and AI & automation on one system of record, with one role-scoped, audited AI agent (chat and voice) that can operate all of it. Supply chain and manufacturing are in early access.
