How Nexus Compares to
Banana, bexio & Odoo.

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.

Built-In Accounting Intelligence
Nexus is Uncomparable.

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.

Email Your Documents — AI Books Them

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.

✦ Live

Swiss Payroll — Fully Automated

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.

✦ Live

Direct Bank Payments via EBICS

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.

✦ Live — first payment confirmed

ELM 5.0 Salary Declarations — All Cantons

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.

✦ Live

COA-Linked Bank Accounts

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.

Duplicate AP Invoice Detection

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.

Year-End Bank Balance Control

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.

Open Balance vs Prior Period

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.

Multi-Currency Bank AI

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.

AP & AR Bank Reconciliation

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.

Contract-to-Invoice Automation

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.

Full Mobile App with AI

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.

Time-Limited Auditor Access

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.

Daily Bank Reconciliation

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.

Architecture
How does Nexus by TTN Work?

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.

Agent 01

Communication Agent

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.

Email ingestion Document routing Email confirmations Payslip delivery
Agent 02

Booking Agent

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.

Journal entries AI account assignment VAT booking FX conversion
Agent 03

Payables & Payroll Agent

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.

PAIN.001 / EBICS Swiss payroll ELM 5.0 XML Duplicate detection
Agent 04

Bank Reconciliation Agent

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.

Statement import AI matching EBICS fetch Daily auto-recon
Agent 05

Data In/Out Agent

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.

P&L / Balance Sheet QR-Bill invoicing Excel exports ELM declaration
Agent 06

Controls & Compliance Agent

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.

For Small & Medium Businesses
Built for Swiss SMEs
& Associations.

Nexus is designed for organisations that want accounting to simply happen — without hiring a full-time bookkeeper, mastering complex software or managing servers.

🏢

Swiss SMEs

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.

  • Startups and scale-ups with high invoice volumes
  • Trading companies with multi-currency suppliers
  • Service firms with recurring client invoices
  • Companies with field staff submitting travel expenses
  • Businesses that work with a fiduciary and want to hand over clean books
🤝

Associations (Vereine)

Swiss non-profits and associations (Vereine) managing member rosters, annual fee invoicing and donation bookings — all in one portal, without separate membership software.

  • Sports clubs and cultural associations
  • Professional bodies and chamber associations
  • Charitable foundations with regular donor invoicing
  • Community organisations needing Swiss QR-Bill invoices
  • Associations that need full accounting + member management in one tool
Why Not the Others?
The Honest Assessment.
B+

Banana Accounting+

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.

bx

bexio Advanced

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.

O

Odoo Enterprise

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.
