How good is the AI really? Can I rely on the texts?

Proposal Air uses Claude, one of the most advanced AI models. The texts are professional and industry-specific. We recommend briefly reviewing each proposal before sending — the AI delivers 90%, the last 10% is your personal touch.

Can I really use Proposal Air for free?

Yes. The free plan includes 5 proposals per month with all core features. No credit card, no subscription. If you need more, you can upgrade anytime.

Do you support the small business regulation (§19 UStG)?

Yes. Simply activate the toggle in settings. After that, no VAT amounts will be displayed and the legally required disclaimer text is automatically inserted.

Is my data secure and GDPR compliant?

Absolutely. Proposal Air is fully GDPR compliant. Your data is encrypted and stored in the EU. You can export or delete at any time. We offer 2FA and passkey support.

Can I create an invoice directly from a proposal?

Yes. Once your client accepts, you create an invoice with one click. All data is transferred. The invoices are GoBD-compliant.

How does the payment feature work?

Connect your Stripe account and enable payment per proposal. After signing, your client can pay directly via credit card or other payment methods. The money goes straight to your Stripe account — Proposal Air never touches your funds. Available on the Pro plan.

Is the electronic signature legally binding?

Yes. Our e-signatures are eIDAS-compliant. Your client signs directly in the browser. The signature is securely encrypted.

How quickly can I get started?

In under 2 minutes. Sign up with Google, GitHub, or email. Enter your business details and start right away.

Can I see if my client opened the proposal?

Yes. The analytics dashboard shows you opening time, device, and viewing duration. So you always know the best time to follow up.

Can I use my own branding?

Yes. Upload your logo — it appears on all proposals and invoices. Your company name and business details are applied automatically.

What happens when I cancel my subscription?

Your subscription runs until the end of the period. You keep access to all created documents and switch to the free plan. No cancellation fees.

You lose hours every week on proposals nobody reads

2-4 hours of writing. Then radio silence. No tracking, no idea if the client ever opened it.

The Problem

Hours of writing

Every proposal from scratch. Copy-paste from old files that never fit. Evening after evening.

Legal uncertainty

GoBD, VAT, small business rules — one wrong sentence and you're in trouble.

Proposals vanish without a trace

PDF sent, client says 'I'll look at it'. Then: silence. For weeks.

Double work for invoicing

Won the deal? Now re-type everything. Into another tool. By hand.

The Solution

AI writes, you do the final touch

Finished copy in seconds. Not hours. You only change what you want.

Compliance? Handled automatically

GoBD, small business regulation, GDPR — one toggle instead of an accountant call.

You know when the client reads

Who opens, when, how long. Stop guessing — follow up at the perfect moment.

Proposal accepted? Invoice ready

One click. All data transferred. Zero re-typing.

From idea to signed deal

AI generation, delivery, tracking, signatures, invoicing — all in one app.

From project idea to finished proposal — in one click

Describe your project, AI handles the rest.

Beschreibe dein Projekt in eigenen Worten — Stichpunkte genügen. Die KI versteht Kontext, Branche und Umfang.
Professionelle Texte, die überzeugen — keine Textbausteine. Jedes Angebot wird individuell formuliert.
Preiskalkulation inklusive — Positionen, Stundensätze, Rabatte und MwSt. werden automatisch strukturiert.
