WinBIZ ships ten times more features than you'll ever use. Magic Heidi is the simple, mobile-first alternative — from CHF 25/month and free up to 3 invoices.
CHF 1,783.65 received
AI extracted CHF 42.50
WinBIZ Cloud is a full Swiss ERP (accounting, payroll, stock, CRM, fiduciary) built for SMEs with employees and a structured fiduciary relationship. Magic Heidi is invoicing and expense software built only for solo freelancers, with AI receipt scanning, native apps on five platforms and Swiss VAT built in. If you work alone, with no employees and no stock to manage, you'll pay roughly three times less for the 20% of features you actually use.
Key takeaways
WinBIZ isn't a bad product. The problem is the gap between what it offers and what a solo freelancer actually needs day to day. Here's what comes up most often.
To stay fair: WinBIZ has things Magic Heidi doesn't. A mature, compliant payroll module, a 900+ partner fiduciary network that can open your file directly, full double-entry accounting, stock and production management, an installed "single-seat" version for people who don't want cloud, long-running French-language support. If any one of those matters to you, don't switch — stay on WinBIZ.
Built in Switzerland, hosted in Zurich, available in four languages (DE, FR, IT, EN) and used by more than 5,000 Swiss freelancers, sole proprietors and self-employed professionals.
Invoices and quotes with the Swiss QR-bill, accepted by every bank.
Photo, PDF or forwarded email: date, amount, supplier, currency and VAT extracted automatically.
Standard method and net tax rate method (Saldosteuersatz/TDFN), with FTA-ready exports.
UBS, PostFinance, ZKB, Raiffeisen, Migros Bank, Neon, Yuh, cantonal banks, with auto-reconciliation.
iPhone, Android, Mac, Windows and web, synced in real time.
50+ currencies with Swiss National Bank rates applied automatically.

That short list is on purpose. Magic Heidi focuses on the 5 or 6 things a solo freelancer does every week, and tries to make them faster than anywhere else.
Target audience, onboarding, mobile, AI scanning, payroll, stock, price, migration: here's where the two products genuinely diverge.
WinBIZ targets SMEs of 2-50 people, with or without a fiduciary. Magic Heidi targets only freelancers: sole proprietorship, Einzelfirma, raison individuelle.
WinBIZ asks you to configure chart of accounts, periods, VAT methods, bank accounts. Magic Heidi is usable in two minutes: name, UID, IBAN, VAT method.
Magic Heidi has native apps on five platforms (iPhone, Android, Mac, Windows, web), synced in real time. WinBIZ Cloud is still workstation-centric.
Both handle QR-bill v2.3 and standard + net tax rate VAT. Magic Heidi imports CSV from the major Swiss banks; WinBIZ has more advanced ISO 20022 connectors for SMEs.
Magic Heidi auto-extracts date, amount, supplier, currency, VAT from a photo or a PDF. WinBIZ has classic document entry, no AI at the core of the product.
WinBIZ has a full Swissdec-certified payroll module: monthly statements, OASI (AHV/AVS), LPP/BVG, accident insurance, salary certificates. Magic Heidi has no payroll module.
WinBIZ has stock, sales CRM with pipelines, even POS extensions. Magic Heidi has a simple client list (notes, history, revenue) but no pipeline and no stock.
WinBIZ Cloud standard ~CHF 69-71/month/seat, freelancer plan from CHF 19/month. Magic Heidi: free up to 3 invoices, Pro CHF 25/month annual or CHF 30/month monthly, all included.
Magic Heidi exports everything any time: full ZIP, CSV, PDF of every invoice. WinBIZ also exports, but in accounting-oriented formats (journals, entries) that are harder to translate.

Plan 1 to 2 hours for a tidy solo freelance setup. Here are the 8 practical steps in order.
From WinBIZ, export your client list (CSV), your products/services list (CSV), your invoice history (PDFs ideally), and your bank entries for the current year (CSV).
Open app.magicheidi.ch or download the app on your platform. Add your name, UID if you have one, IBAN, and pick your VAT method (standard or net tax rate / Saldosteuersatz).
Magic Heidi accepts CSV client imports. Check that the columns (name, address, email, language, currency) map cleanly. Re-creating 5-10 main clients by hand is often faster than a messy import.
Check the Swiss rates (8.1%, 2.6%, 3.8%) and pick the method (standard or net tax rate). If you were on net tax rate in WinBIZ, keep the same rate in Magic Heidi to avoid confusion at period-end.
Download the CSV of your bank accounts from e-banking, and import it into Magic Heidi. The system detects payments and proposes automatic reconciliation against the invoices you'll create.
Pick a client, add your services, check the VAT rates, generate the QR-bill. Send it directly by email from Magic Heidi.
Keep your WinBIZ file archived for already-closed fiscal years; your fiduciary or the FTA can come back to it if needed. From the new fiscal period (typically 1 January), do everything in Magic Heidi.
If you work with a fiduciary, tell them about the change. Magic Heidi exports clean CSV files and an annual recap PDF ready for the tax return. Most fiduciaries accept this format.
Over 5,000 freelancers and sole proprietors use Magic Heidi every day.

Honest comparison: WinBIZ has more features. But for a solo Einzelfirma, Magic Heidi covers what I actually do every week, faster, and on every device. Recommended.

Yes, as long as your needs are strictly freelance: invoicing, expenses, VAT, payment tracking, clients. If you used WinBIZ only for these, Magic Heidi covers everything you were doing, more simply. If you used WinBIZ for payroll, stock, or full double-entry accounting, Magic Heidi won't replace those functions.
Yes. Magic Heidi handles the Swiss rates (8.1%, 2.6%, 3.8%), the standard method and the net tax rate method (Saldosteuersatz/TDFN). Exports are ready for the FTA return. The QR-bill v2.3 is SIX-compliant.
Partially. You can import your clients via CSV and your bank statements via CSV. WinBIZ invoice history is better kept as a PDF archive; you don't need to re-import everything. Most freelancers switch at the start of a new fiscal period and keep WinBIZ history archived.
Magic Heidi isn't for you. Magic Heidi has no Swissdec payroll module. If you pay even one employee, stay on WinBIZ, or use a dedicated payroll tool alongside. We'd rather be honest about the limit than fake half-decent payroll.
Better, actually. Magic Heidi has native iPhone and Android apps designed to invoice and scan from your phone. WinBIZ Cloud is accessible on the move but still optimised for the desk. If you often invoice on the road, that's a decisive argument.
Stay on WinBIZ if: you have employees, you manage stock, you're required to keep double-entry books, your fiduciary works directly inside your WinBIZ file and that integration saves you time, or you've poured hours into an ERP setup that works. The cost of switching isn't zero, and it has to be justified by a real gain.
Depends on your current WinBIZ plan. From WinBIZ Cloud standard at CHF 69/month, switching to Magic Heidi Pro annual at CHF 25/month saves about CHF 528/year. From the WinBIZ freelancer plan at CHF 19/month, the financial saving is smaller (around CHF 50/year), but you gain AI scanning, native apps on five platforms, and a product built only for freelancers.
Yes. Magic Heidi hosts data in Zurich, Switzerland. Encryption at rest and in transit, automatic backups, full ZIP export at any time. Like WinBIZ, the product is Swiss end to end.
One Pro plan, all-in. Cancel any time.
The best way to know if Magic Heidi is the right WinBIZ alternative: send three real invoices. No time limit, no credit card. Keep WinBIZ open in parallel and compare on your actual workflow.
If after those three invoices you find Magic Heidi simpler, faster and a better fit for your solo freelance work, you can move to Pro for CHF 25 per month (annual) with a 30-day money-back guarantee. If you find WinBIZ still suits your situation better, you'll know that too, and you've avoided a bad purchase.
