The Operating Platform for Accounting Firms
One Platform. Every Client.
Real-Time Books.
FynOS replaces the patchwork of accounting software instances, spreadsheets, and manual reconciliation your practice runs on today. So your team spends time on advisory, not data entry. Built specifically for firms serving inventory-led businesses.
The Reality
Your Tools Weren't Built for This
Most accounting firms outgrow their tools long before they outgrow their ambition.
The Talent Crisis Is Permanent
The profession is losing talent faster than it can replace. Fewer graduates, better-paying alternatives in tech and industry, and a pipeline that can't keep up with demand. Every client you win requires people you can't find. You need a platform that absorbs the work, not a tool that creates more of it.
Compliance Eats Your Best Hours
Your senior associates spend 80% of their time on low-value compliance work: bank recs, transaction categorization, month-end close. Meanwhile, the high-value advisory work sits undone. The problem isn't your people. It's your tools.
Your Stack Is 6 Tools Duct-Taped Together
One tool for books. Another for documents. A third for workflow. Excel for reporting. A shared drive for workpapers. And chat groups to coordinate all of it. Every integration point is a failure point. Every manual handoff is a realization leak.
Who This Is For
Is This Your Book of Business?
You serve D2C brands, Amazon sellers, Shopify stores, distributors, and manufacturers. If your average client has more than 3 sales channels and a cost-of-goods problem, FynOS was built for your book of business.
Manufacturers
Bill of materials, WIP tracking, production costing. Multi-step processes where every GRN has cost and inventory implications.
Distributors
Landed cost allocation, warehouse inventory, multi-location tracking. The complexity that makes these clients painful on standard accounting software, handled natively.
E-Commerce Sellers
Multi-channel revenue, marketplace settlements, returns that reverse COGS. Every platform has different fee structures and settlement cycles.
Importers & Exporters
Multi-currency transactions, duty allocation, foreign vendor management. Cross-border complexity without enterprise ERP pricing.
If your portfolio includes businesses doing $5M–$50M in revenue with physical inventory across multiple channels, you're exactly who we built this for.
The Platform
What Your Practice Looks Like on FynOS
Here's what your practice looks like on FynOS.
Portfolio Command Center
Every client's close status, exception queue, and cash position in one view. Know which clients need attention before they call you. No more logging into dozens of separate accounting logins.
Onboard Clients in Hours, Not Weeks
Templatized Chart of Accounts, automated posting rules, and pre-built reconciliation workflows by industry. Your 50th client setup should be as fast as your 5th.
AI That Eliminates the Grunt Work
Automated bank categorization, smart reconciliation matching, AI-powered invoice parsing. Your associates handle exceptions, not every transaction. The platform learns from corrections.
Built for Inventory-Led Businesses
Native inventory valuation (FIFO, weighted average, specific ID), landed cost allocation, and multi-entity consolidation. The complexity your distribution and manufacturing clients need, without the enterprise ERP price tag.
Complete Audit Trail, Zero Scramble
Every transaction logged with user, timestamp, and approval chain. Segregation of duties enforced by the platform. Export evidence packs in one click.
Continuous Close, Not Month-End Close
When every business event auto-posts to the GL in real time, month-end close transforms from a 6-10 day ordeal into a few hours of review and sign-off. The books are always current.
The Advisory Wedge
See What Your Clients Can't
Beyond running the books, FynOS surfaces the insights that let your firm sell advisory services, turning a $3,000/month compliance engagement into an $8,000/month advisory relationship.
Cash Flow Forecasting
Forward-looking 13-week cash flow projection based on real AP/AR data. Present this to your client as a CFO-grade deliverable. Billable advisory output generated by the platform.
Working Capital Dashboard
Days Sales Outstanding, Days Payable Outstanding, inventory turns, cash conversion cycle, all computed automatically. Spot problems before your client does. That's how you become irreplaceable.
Inventory Health Scoring
Aging analysis, slow-moving inventory flags, stockout risk, dead stock identification. For distribution and manufacturing clients, this is the insight their previous accountant never provided.
Client Health Alerts
Anomaly detection: unusual expense spikes, margin compression, receivables aging past thresholds. Proactive alerts, not month-end surprises. This is how you become indispensable.
Board-Ready Reporting
Automated monthly and quarterly reporting with variance analysis, KPI dashboards, and trend visualization. Deliver this to your client's board, branded as your firm's advisory output.
Margin Analysis by SKU & Channel
Contribution margin by product, by channel, by customer. Know which SKUs make money and which ones destroy it. The analysis that turns a compliance firm into a strategic advisor.
The Partnership Model
Your Firm + FynOS = A Complete Ecosystem for Your Clients
FynOS isn't software your clients use instead of your firm. It's the platform your firm uses to serve them at a level that wasn't possible before.
You bring the relationship. FynOS brings the infrastructure.
Your firm owns the client relationship, the advisory layer, and the strategic context. FynOS handles the reconciliation, the GL, the inventory valuation, and the close, automatically. Together, you deliver something neither could alone.
Expand what you offer without expanding your headcount.
Real-time inventory margin, automated AP/AR, and continuous close become part of your service offering the day you onboard a client on FynOS. No new hires. No new toolchains. New value delivered immediately.
Your clients get enterprise-grade ops at SMB cost.
The $10M D2C brand can't afford NetSuite. They don't need to. FynOS gives them (and you) the visibility and automation that used to require a six-figure ERP and a team to run it.
Design partners shape the product.
Early partner firms work directly with the FynOS team to shape workflows, integrations, and reporting for inventory-led clients. Your input becomes the product. Your clients become the reference.
We're actively looking for design partner firms: accounting practices that serve D2C brands, Amazon sellers, and multi-channel inventory businesses. If that describes your book of business, let's build this together.
Two Ways to Partner
Choose Your Path
Outsourced Accounting Partner
“Run your client books on FynOS”
Use FynOS as your firm's operating platform. Onboard clients into a standardized chart of accounts, automate reconciliation, and manage every client's books from one dashboard. Your team does the judgment work. FynOS handles the repetitive work.
Your firm bills the client directly. FynOS is your cost of delivery, not a line item your client sees. Margin structure discussed during partner onboarding.
Best for
Outsourced accounting practices, bookkeeping-to-advisory firms scaling past 30 clients, multi-client service providers
Advisory & Implementation Partner
“Help clients get more from FynOS”
Offer implementation, industry-specific configuration, and ongoing advisory services to businesses running on FynOS. Inventory costing strategies, working capital optimization, cash flow forecasting: your expertise on our data.
You set your rates. As FynOS grows, we route implementation and advisory requests directly to our partners. No platform fees on your advisory revenue.
Best for
Tax advisory firms, industry specialists (manufacturing, distribution, e-commerce), fractional CFO practices
