Nexus is not accounting software. It is a virtual employee — an AI agent that archives your documents, reads your invoices, books your entries, handles VAT, prepares your P&L and Balance Sheet, and manages your vendor master data. Automatically. Every month.
Other accounting solutions are tools — you still need to operate them. Nexus is an agent that operates itself. Here is what that means in practice for a Swiss SME.

No competitor offers the depth of accounting intelligence that Nexus embeds by default. These are not add-ons or premium modules — they are woven into the platform and run automatically.
Forward any payable, receivable, bank statement, or contract to your Nexus AI Accountant by email. The AI extracts, classifies, and books the document automatically — then replies to confirm what was recorded. No login required. FINCARGO uses this workflow exclusively — nobody logs into the portal anymore.
Nexus calculates all Swiss statutory deductions — AHV/IV/EO, ALV, BVG, UVG (NBU), KTG, and source tax per canton. Payslips are generated and emailed to each employee automatically. The payroll journal entry is booked and salary tax provisioned. Tested live with real employees.
Nexus generates ISO 20022 pain.001 payment files from your open payables, travel expense reimbursements, and payroll runs — and submits them directly to your bank via the EBICS protocol. The first live payment was transmitted and confirmed. No re-keying. One click from the portal to the bank.
Nexus generates the ELM 5.0 XML file required for salary reporting across all Swiss cantons. Each employee's gross salary, deductions, and source tax are structured to cantonal requirements. Download and transmit directly to the relevant government agencies — no manual preparation needed.
Each bank account is mapped directly inside the Chart of Accounts. Every transaction is posted to the correct ledger account automatically — no manual account coding, no mapping tables to maintain.
Before any payable is booked, Nexus scans for duplicates — same supplier, same amount, overlapping date range. Duplicate invoices are flagged immediately, preventing double payments and double entries.
At year-end, Nexus verifies that every bank account balance in the ledger matches the closing balance on the uploaded bank statement. Discrepancies are surfaced before they become audit findings.
Nexus tracks open payables and receivables across periods and compares them against prior balances. Unexplained movements — invoices that disappeared, amounts that shifted — are immediately visible.
Nexus recognises multi-currency bank accounts from uploaded statements, automatically applies the correct exchange rate per transaction, and books FX gains and losses to the appropriate ledger accounts.
Bank statement lines are automatically matched against open payables and receivables. Payments clear the corresponding invoice, update the ledger, and flag any unmatched line — all without manual intervention.
Recurring contracts flow automatically into periodic invoices, which flow into journal entries, which update P&L — end to end, without a single manual step. Set the contract once; Nexus handles every cycle.
From your phone: capture travel expenses, upload payables and receivables, photograph bank statements, and archive any document. AI recognition runs on every upload — same engine, same accuracy, same instant booking as the desktop.
Grant your external auditor or fiduciary read-only access to a defined scope of data — specific periods, specific document folders — with a built-in expiry date. Access is automatically revoked when the window closes.
The next milestone: Nexus will connect to the bank via EBICS each morning, fetch the previous day's transactions, and reconcile them automatically against open payables and receivables. Companies will have a daily close-of-books — zero backlog, zero manual import.
Nexus is not one AI — it is a team of six specialised agents, each owning a distinct part of the accounting workflow. Documents flow in, agents process them autonomously, results flow out to your ledger, bank, and government authorities.
Handles all inbound and outbound communication with users. Receives documents forwarded by email, triggers the processing pipeline, and sends back confirmations, payslips, booking summaries, and alerts. Users interact naturally — by email or mobile — without ever logging in.
The accounting brain of Nexus. Reads extracted invoice and bank data, assigns the correct debit and credit accounts from the Chart of Accounts, applies VAT codes per line, and posts journal entries automatically. Supports multi-currency with real-time FX conversion and FX gain/loss booking.
Manages the full accounts payable workflow — duplicate detection, payment scheduling, and PAIN.001 XML generation for direct bank submission via EBICS. Runs Swiss payroll end-to-end: deductions (AHV, ALV, BVG, UVG, KTG, source tax), payslip email, financial booking, and ELM 5.0 XML for all cantonal authorities.
Processes uploaded or EBICS-fetched bank statements and reconciles each transaction line against open payables and receivables. Clears matched invoices automatically, books unreconciled lines to suspense, and flags anomalies for review. Daily reconciliation via EBICS is the next milestone, giving companies a live close-of-books every morning.
Handles all structured data exchange — exporting P&L, Balance Sheet, VAT reports, journal exports, and Excel ledgers; generating QR-Bill invoices for receivables; importing Chart of Accounts, historical data, and COA mappings. Also manages ELM XML generation for government salary declaration submissions across all cantons.
Watches every booking for risk signals. Runs duplicate AP invoice detection before each posting. Verifies bank balances against uploaded statements at year-end. Tracks open AP/AR movement between periods and surfaces unexplained changes. Manages time-limited, scoped auditor access with automatic expiry — no permanent credentials, no residual risk.
No per-user fees. No AI add-ons. No hidden costs. Every plan includes all features, unlimited AR invoices, unlimited travel expense users, and up to 6 company users. Choose by your AP invoice volume.

Start with Pro →Nexus is designed for organisations that want accounting to simply happen — without hiring a full-time bookkeeper, mastering complex software or managing servers.
Small and medium-sized companies with regular payables, receivables and employee expenses who want a complete accounting record without the overhead of a traditional ERP.
Swiss non-profits and associations (Vereine) managing member rosters, annual fee invoicing and donation bookings — all in one portal, without separate membership software.
Excellent for accountants who know exactly what they are doing. Lowest cost of ownership in the market — but 100% manual. Every line must be typed. There is no AI, no cloud sync, no collaboration. For a growing SME, the time cost far outweighs the CHF 15/month licence.
The Swiss gold standard for bank integration and QR-billing. But AI scanning costs extra: CHF 39/month for the Kontera Silver add-on — and it's capped at 100 documents/month. Exceed the cap and you pay CHF 0.50 per invoice. Total cost for 2 users with AI: CHF 91/month. Beyond that, bexio is software, not an agent: you still do the accounting work.
A powerful full ERP — ideal if you need CRM, inventory and website management alongside accounting. But for an SME that just needs accounting done, Odoo is vastly over-engineered. AI scanning runs on a paid token model — every document has a marginal cost. Implementation takes weeks.
From CHF 74/month. Everything included. No software to install. Most companies are live within 48 hours of signing up.
