Key takeaways
- Fixed Assets CS manages depreciation schedules; FileCabinet CS manages document storage. Neither reads an invoice or decides where a new document belongs.
- An n8n + Claude workflow reads incoming asset purchase invoices, extracts the depreciation-relevant details, and stages the entry — instead of someone re-keying it by hand.
- The same workflow reads incoming client documents and files them into the correct FileCabinet CS location automatically, based on what the document actually is.
- This is filing and data-entry labor, not tax judgment — exactly the kind of work that shouldn't need a dedicated person's full attention.
- Firms running this stop treating manual filing as a fixed cost of using CS Professional Suite.
Two Good Tools With the Same Blind Spot
Fixed Assets CS is built to track depreciation schedules once an asset is entered correctly. FileCabinet CS is built to store client documents once they're filed correctly. Both do their actual job well. Neither one reads an invoice, decides what an incoming document is, or files anything on its own — that step, the one between receiving something and correctly recording it, has always been a person's job, and it's the same manual-entry problem underneath both tools.
Where the Manual Work Actually Lives
A new asset purchase comes in as an invoice or a receipt. Someone has to read it, pull out the purchase date, cost, useful life category, and vendor, and manually enter it into Fixed Assets CS. A client sends a document — a signed engagement letter, a source document, a prior-year return — and someone has to look at it, figure out which client folder it belongs in, and file it correctly in FileCabinet CS. Neither task requires a CPA's judgment. Both consume a CPA's time anyway, because there was no automated layer that could read a document and know what to do with it.
The Workflow: Claude Reads, n8n Routes
We connect an n8n workflow upstream of both tools: incoming asset invoices are read by Claude, which extracts the depreciation-relevant fields and stages a structured entry for Fixed Assets CS, flagged for review rather than auto-committed. Separately, incoming client documents are classified by type and client, then routed and filed into the correct FileCabinet CS location automatically. In both cases, the workflow does exactly what a person used to do manually — reading, deciding, and entering or filing — just without treating it as billable staff time.
What This Actually Changes
It doesn't change what Fixed Assets CS calculates or how FileCabinet CS stores documents. It changes who does the reading and entering before either tool is touched. A firm that used to dedicate real hours per week to asset data entry and document filing gets those hours back — not because the software got smarter, but because the manual gap in front of it finally has something automated sitting in it.
Frequently Asked Questions
Does this replace Fixed Assets CS or FileCabinet CS?
No — both remain the system of record. The workflow only automates the reading and entry work that used to happen before information reached either tool.
Does the system make final entries without review?
No. New asset entries are staged for a preparer's review before being committed — the workflow removes the data-entry labor, not the professional sign-off.
What kinds of documents can it classify for FileCabinet CS?
Any recurring client document type your firm handles — engagement letters, source documents, prior returns, correspondence — based on what the document actually says, not just a filename.
Is this specific to the Thomson Reuters CS Professional Suite?
The pattern applies to any practice-management stack; we've built it specifically against Fixed Assets CS and FileCabinet CS because that's what a large share of CPA firms already run.
