— FOR FREELANCERS, SELF-EMPLOYED INDIVIDUALS & SMALL BUSINESSES —

billoq is the easiest way for freelancers and the self-employed to send invoices. No
overhead, no unnecessary features, no steep learning curve. Whether you're a freelancer, self-employed on the side, or run a small business: with billoq, you always have your invoicing software with you.

Typical users:
→ Freelancers and creatives (designers, copywriters, photographers, developers)
→ Tradespeople and service providers
→ Consultants and coaches
→ Self-employed individuals and small business owners

— NOT A TRADITIONAL INVOICING PROGRAM —

Traditional invoicing software is designed for desktop computers – billoq isn't.

billoq was designed from the ground up as a mobile invoicing app. You create invoices whenever and wherever you want: on your way to a client, between appointments, or immediately after completing a job.

— SMALL BUSINESS OWNER? FULLY SUPPORTED. —

As a small business owner according to § 19 of the German VAT Act (UStG), you don't charge VAT on your invoices. billoq recognizes this automatically: As soon as all items are entered without VAT, the app creates a legally compliant invoice according to the small business regulation – without any manual settings.

— E-INVOICE & XRechnung —

E-invoicing has been mandatory in Germany since 2025 for all B2B transactions.

biloq supports the XRechnung standard and the routing ID for invoices to public sector clients. This means you're ready for the new invoicing requirements – directly from within the app.

— DOCUMENTS & STATUS AT A GLANCE —

Never lose track. billoq shows you the status of each document: paid, pending, or overdue. Search by customer name or invoice number, filter by invoices or quotes – you can immediately see who still needs to pay.

— SERVICE CATALOG FOR FASTER INVOICES —

Do you regularly invoice the same services? Create them once in the service catalog and add them to new invoices with a single tap. This saves time and makes creating invoices even faster.

— CREATE & SHARE PDFS DIRECTLY —

One tap is all it takes: billoq generates a professional invoice PDF, and you can share it directly from the app via email, WhatsApp, or another channel—no computer, no detours.

—SECURE IN THE CLOUD —

Your invoices and customer data are securely stored in the cloud. You have access from any device—and you won't lose a single invoice, even if you switch devices.
