One tiny office instead of five tools.
Customers, offers, hours, invoices, finance.

yourtinyoffice is a mobile invoicing web app for freelancers and small businesses in Austria, Germany and the Netherlands. It covers leads and customers, projects with hour budgets, offers, time tracking, projects shared with partners and subcontractors, e-invoices, recurring invoices, expenses with receipts, bank statement matching, a read-only login for your tax advisor and mail delivery without becoming an accounting suite.

yourtinyoffice creates EN 16931 CII XML, combines it into a Factur-X/ZUGFeRD PDF/A-3 and technically validates that output. Country rules, tax treatment, reporting channels and recipient requirements can add obligations.

Yes. Documents and the accompanying mail texts are available in German, English, French, Italian, Spanish and Dutch. The language is stored with the customer and can be changed for each document. The app itself is available in English and German.

Yes. Invoices support EUR, CHF, GBP, USD, INR and more than 30 currencies published by the European Central Bank, from PLN and SEK to AUD, CAD and JPY. ECB conversion and printed EUR values are optional and appear only when enabled.

Based on the seller country, customer country and a checked customer VAT ID, the invoice form suggests domestic VAT, EU reverse charge, non-EU treatment or small-business exemption. Review the tax treatment before issuing.

It is built for freelancers and small businesses based in Austria, Germany or the Netherlands, alone or with a small team, whose clients pay by invoice. In all three countries every invoice you issue, at home and abroad, can be done right without a national e-invoicing platform, and your clients can be anywhere. For Germany's e-invoice duty you send Factur-X/ZUGFeRD e-invoices, and on Basic and Pro the e-invoices you receive are read into your expenses. It is not a bookkeeping suite (your tax advisor keeps the books) and not a till for shops that take cash or card on the spot. More countries follow one at a time once we have checked them.

Free costs nothing: 2 invoices per month, customers, projects, time tracking and expenses, all languages and currencies, mail delivery via the yourtinyoffice server. Basic costs € 12 net per month and adds unlimited invoices, recurring monthly invoices, offers, payment reminders, the lead pipeline, receipt photos, PDFs and e-invoices for expenses, receipt reading with your own AI key, bank statement matching and the monthly export for your tax advisor; expenses by e-mail are coming soon. Pro costs € 20 net per month and adds up to 3 team members, projects shared with partners, a read-only login for your tax advisor, your own invoice and offer layouts and delivery via your own SMTP server. Cancel monthly.

All data and documents are stored in the EU: the database, files and backups in Ireland, the application on servers in Germany. Every tenant is strictly separated from others at the database level, and the data processing agreement is public.

Yes, with Pro. Copy the prepared prompt from the settings, attach your current invoice as a PDF or screenshot and give both to any AI assistant, such as ChatGPT, Claude or Gemini. It writes a Typst layout, which yourtinyoffice checks against sample invoices for every VAT case before you activate it. Remove customer and bank details from the attachment first. The e-invoice data stays EN 16931 compliant.

Yes, with Pro. Invite a partner by e-mail and pick the projects they may work on. The partner books time in their own yourtinyoffice account, on any plan, and invoices you from it. Their hours also appear on your project, so you can invoice all of them to your customer, by hand or with a recurring monthly invoice.

Yes, with Pro. Invite your tax advisor by e-mail. They create their own login at no cost and without a subscription, and see your company's tax details and the months you hand over, with their issued invoices and your expenses with their receipts. They download a single month or the whole year as a ZIP and send you a query about a month, an invoice or an expense when something is missing; you get an e-mail and mark it resolved. If they work with DATEV or BMD NTCS, they set up the booking export once, with their own accounts and tax codes, and every monthly ZIP then carries the matching booking file next to an MT940 bank statement. Besides queries and the booking export setup, your advisor cannot change anything: not your invoices, expenses or receipts, and they see no customers, offers or time entries. You can revoke the access at any time, and one advisor login works for several clients.

Yes, with Basic or Pro. Upload the EUR CSV export of your business account, check the suggested columns and confirm the transaction preview. No AI assistant or separate setup is needed; confirmed formats are remembered. Debits are matched with your recorded expenses, customer payments are matched with open invoices and mark them as paid on the booking date, and each expense shows whether its receipt is still missing. The app remembers what a counterparty means for the next upload. When a month is complete you close it, and your tax advisor sees that it has been handed over. yourtinyoffice does not connect to your bank and does no bookkeeping.

Yes, with Basic or Pro and your own AI provider. yourtinyoffice runs no AI of its own: you add an API key for OpenAI, OpenRouter, Langdock or another OpenAI-compatible endpoint in the settings. When you upload a receipt photo or PDF in the expense form, it is sent to that provider under your own contract, and the proposed vendor, date, total, VAT rate and category are filled in for you to check before saving. The key is stored encrypted and can be removed at any time; without a key nothing is sent. E-invoices are still read from their structured data, without AI.
