Typical invoice items in HVAC & plumbing
Whether boiler service, leak detection or a complete bathroom: HVAC invoices mix flat rates (maintenance, travel) with measured and material items. Show maintenance flat rates as their own item — it makes follow-up work plannable — and separate the labour share for private customers (§35a tax bonus).
E-invoicing & public contracts
Jobs for municipalities, housing associations and public clients increasingly require the e-invoice (XRechnung). DasHandwerk.xhub generates it automatically — no add-on module and no surcharge.
