DELKARO HANDWERK is a German-operated SaaS suite for small craft businesses that want one place for customers, job sites, quotes, scheduling, materials, time entries, and invoices. The product is built around OFFICE in the browser, with a native Android field app for site capture, and German-language workflows aimed at painters, electricians, HVAC, roofers, and similar trades.

It exists because many small German Handwerk shops still stitch together spreadsheets, messenger threads, and separate quoting tools. HANDWERK keeps the job file as the spine so an enquiry can become a quote, a planned deployment, site documentation, and a billable invoice without retyping the same customer and site facts.

Access is currently via a pilot application rather than open self-serve signup. Core customer data is hosted with Hetzner in Germany. Optional AI assists can send selected media and business context to OpenAI, where US processing is possible, so buyers who need EU-only AI paths should treat that as a hard filter.

Shortlist for German craft shops that want one OFFICE for customers, quotes, scheduling, materials, Android site capture, and e-invoices on Hetzner Germany hosting. Skip for self-serve signup, self-hosting, EU-only AI, or payroll/bank/DATEV depth. Prefer Nozbe or Stackfield for general EU project work, or Microsoft 365 / Salesforce if you already standardise there.

Key capabilities

Customers, contacts, sites/assets, enquiries, tasks, documents, and the full order history stay on one job file so office staff can move from request to quote, preparation, execution, and billing without rebuilding context.

Build quotes from measurements, catalogue positions, and labour/material shares; share a personal customer decision link; continue into progress and final invoices. Supported outputs include checked XRechnung or ZUGFeRD/Factur-X PDF packages when format validation is set up.

Assign people and sites in day/week views, surface conflicts and travel buffers, record absences, and capture start/end/pause times on site for later office release. Time PDFs/CSVs are for further processing; the product does not create payroll.

Native Android app for site overview, times, photos, messages, and proofs, including local store-and-forward for supported offline changes. Browser OFFICE remains the hub; store-distributed iOS for that field app is not advertised on the functions page.

Track material demand on the job, prepare supplier orders, record partial/complete deliveries, and follow warehouse moves, take-out, and returns so site supply stays tied to the same order file.

Eleven OFFICE helpers can propose structured data from notes, photos, or messages. Suggestions require explicit human acceptance. Selected content may go to OpenAI with possible US processing; exclusive EU AI processing is not promised.

Best fit when

  • Small German-speaking craft businesses that want one job file from enquiry to invoice
  • Teams that need weekly crew planning plus Android site time/photo/message capture
  • Buyers who require German e-invoice outputs (XRechnung / ZUGFeRD) from the same operational system
  • Firms willing to join a personally onboarded pilot and accept a product still being refined with users
  • Organisations that accept proprietary SaaS on Hetzner Germany and will contract an Art. 28 DPA

Poor fit when

  • Buyers that need immediate self-serve signup, public APIs, or self-hosting
  • Organisations that forbid any US subprocessor path even for optional AI or mobile push
  • Companies needing payroll generation, live banking, or finished DATEV accounting inside the product
  • Crews that require a store-distributed iOS field app as a hard prerequisite without confirming alternatives
  • Enterprises that require published ISO 27001 / SOC 2 evidence before any pilot

Consider instead when

  • When: You need general EU team tasks/projects rather than craft quoting, materials, and Baustelle workflows

    Consider: Nozbe or Stackfield

    Stronger as collaboration/project tools than as Handwerk ERP substitutes.

  • When: You already standardise on a horizontal CRM or productivity suite and only need light job tracking

    Consider: Salesforce or Microsoft 365

    Broader ecosystem and integrations; weaker native German craft invoicing and site materials flows.

  • When: You need EU-only processing including AI assists with no US model providers

    Consider: A craft or ERP vendor that publishes an EU-only AI path

    DELKARO discloses possible US processing for OpenAI-backed assists and does not promise exclusive EU AI.

No known US parent. Core path is EU-operated Hetzner Germany. Overall posture is partial because optional AI and mobile push can involve US-group processors. Indicative only, not legal advice.

Considerations & known limitations

  • MediumPilot-stage product and access model

    Entry is application-based for a small pilot cohort. Functions may still have limits or defects; individual feature requests are not guaranteed.

  • MediumOptional AI can send data to OpenAI/US

    When AI recognition or preparation is explicitly requested, selected media, text, and business context may be processed by OpenAI with possible US transfer. Exclusive EU AI processing is not promised.

  • LowMobile push via Google FCM / Apple APNs

    Optional push notifications use platform vendors that may process routing identifiers outside the EU. Product remains usable without push.

  • MediumNo public ISO/SOC or independent audit

    Buyers that require published ISO 27001, SOC 2, or third-party security audit PDFs will not find them on the reviewed pages.

  • MediumSingle-person operating company

    Imprint and About identify Daniel Sloman as the sole responsible operator. That aids accountability but concentrates continuity and support capacity risk.

Open questions for due diligence

  • Will the signed Art. 28 AVV and current subprocessor annex be provided before real customer data is loaded?
  • Which HANDWERK workflows are production-ready for this trade versus still experimental in the pilot?
  • Can AI features be disabled tenant-wide for buyers that forbid OpenAI/US transfers?
  • What is the supported path for iPhone-only crews given no App Store iOS field app on the functions page?
  • Are restore-test results, RPO/RTO, and TOMs available under NDA for due diligence?

Veelgestelde Vragen

Access is currently through a pilot application. The vendor reviews trade fit, agrees which workflows are ready, and provisions access personally. An application is not an order and not an automatic approval.

HANDWERK privacy documentation states primary operation at Hetzner Online GmbH on systems in Germany, with encrypted backups also at Hetzner in Germany. Optional AI features may send selected media and business context to OpenAI with possible US processing. Optional mobile push can involve Google FCM and Apple APNs. There is no promise of exclusive EU processing for those optional paths.

Yes according to the vendor: HANDWERK privacy text states craft-business customer data is processed under an Art. 28 agreement, and the general terms require a separate Art. 28 contract before real customer data may be processed as a processor. A public downloadable AVV file was not found on the website during research, so request the signed DPA and subprocessor list during pilot setup.

No. Time exports support downstream payroll tools but DELKARO states it does not create payroll. Payment assignment works from imported CSV turnover suggestions without a direct bank connection. Accounting handoff is file-based (for example PDF/CSV/originals packages), not a finished DATEV live link.

A native Android app is in use for site work, with offline paths for supported captures. OFFICE runs in the browser. The functions overview says iOS App Store distribution for that field app is not offered there; confirm current device support if your crews are iPhone-only.

The product FAQ states supported areas can leave via CSV exports, a scoped JSON export, and invoice PDFs in an accounting package. The JSON export is not a full server restore. Agree the exact handoff scope during onboarding; contractual takeaway windows are described as generally 30 days after contract end unless legal retention applies.
