What you can do

Invoicing — Create and edit invoices, quotes, and recurring schedules, including document templates, line discounts, units, service dates, payment links, and ZUGFeRD e-invoices; cancel an issued invoice with a Stornorechnung, credit part of it with a Rechnungskorrektur, or make a delivery note (Lieferschein) from an invoice or an approved quote

Bookkeeping — Categorize transactions, match receipts, and verify entries

Automation rules — "Always book Telekom to Internet costs": preview, create, and manage rules that categorize matching transactions automatically

Client Management — Maintain your client database and contact details

Products & Services — Keep a catalog of what you sell, with prices, VAT rates and units, and fill invoice lines from it

Tax Filing — Generate Finanzamt previews, file VAT returns, and track deadlines

Company Overview — Check your balance, revenue, and financial health at a glance

Company Formation — Found a German GmbH or UG: collect the founders' data, check the name against the Handelsregister, generate the founding documents (Musterprotokoll, Gesellschafterliste), match with a notary, and track every step through to registration

Documents — Upload and attach receipts, invoices, and supporting files

createattachment.fileurl, bulk fileurls, and structured document imports accept HTTP(S) download links, including unexpired presigned S3 URLs with query parameters. Pass the entire link unchanged; the file host must accept the request without additional authorization headers. The URL downloader has no domain allowlist, URL-length cap, or explicit file-size cap. Its connect/read timeout is 30 seconds (not a total download deadline). The separate browser upload route defaults to 50 MiB, configurable with MCPUPLOADMAXSIZE; API file validation still applies.

URL download failures return an error message and code: downloadhttperror (with httpstatus), downloadtimeout, downloadnetworkerror, downloadstorageerror, or downloaderror. A 403 from the file host can mean an expired or rejected signature; obtain a fresh link and check the host response. Bulk uploads include downloaderrors for failed URLs, indexed within fileurls followed by URL entries from the deprecated filepaths alias; successfully fetched files are still uploaded. Structured imports report errors per document. Download errors omit signed URLs, and temporary downloads are cleaned up after use or cancellation.
