Luxembourg businesses work in French, German, Luxembourgish and English, often within one week. Accounting documents need to keep up without creating errors.
Three things that matter most in Luxembourg
- Create invoice and quote templates in each language you use and apply them by customer preference.
- Configure 17% VAT and reverse-charge rules for cross-border EU customers carefully, with clear audit notes.
- Keep supplier documents attached to transactions to simplify reviews by accountants and authorities.
A practical checklist
Use this list as a starting point and adapt it to your size, sector and the advice of your local professionals. It is general guidance, not legal or tax advice.
- Decide where documents live: attach receipts and contracts to transactions so audit requests are quick.
- Schedule a month-end checklist with owners and dates, and review it after the first two closes.
- Connect bank feeds and create rules so routine transactions need review, not typing.
- Confirm the tax set-up with your accountant against the Administration de l'enregistrement, des domaines et de la TVA, using a sample period before going live.
- Configure the chart of accounts, currency (EUR) and numbering series once, then lock them down.
Local context: Luxembourg
Businesses in Luxembourg operate under 17% VAT, supervised by the Administration de l'enregistrement, des domaines et de la TVA, and commonly use S.à r.l. and S.A. companies. On invoicing and digital records: e-invoicing requirements for public contracts via Peppol. Records and reporting expectations follow from this: Luxembourg GAAP reporting and periodic VAT returns. Where your data sits also matters, so check the hosting region you choose, for example the Zoho EU data centre.
