Features

Everything an invoice needs. Nothing more.

HEPLANO Rechnung covers everyday invoicing — without unnecessary complexity, without features that never get used.

Create invoices

Professional invoices in a few steps — with customer and item data you can reuse for the next invoice.

Small-business VAT scheme

Invoices under Germany's §19 UStG small-business scheme with the legally required notice — the app won't let an invoice be marked as both small-business and VAT-liable at once.

ZUGFeRD & PDF/A-3

Electronic invoices in the ZUGFeRD format (EN16931 profile) straight from the app — for e-invoicing requirements in B2B business.

GoBD numbering

Gapless invoice numbers and invoices that become immutable once finalized — corrections only via a cancellation invoice, exactly as tax authorities require.

Tax overview

VAT broken down by rate for a chosen period, on either an accrual or cash basis — the basis for your VAT advance return.

Payments at a glance

Track partial payments and see open, partially paid or overdue invoices at a glance.

Customers & items

Set up recurring customers and items once, reuse them in every new invoice.

Offline from the ground up

Day-to-day invoicing works offline — only the purchase and the subscription's periodic check need a brief internet connection.

Backup & restore

An encrypted backup with a password you choose, restorable at any time.

FAQ

Frequently asked questions

Coming soon
HEPLANO Rechnung is a mobile app for writing invoices for small businesses and freelancers — with Germany's small-business VAT scheme, ZUGFeRD and a tax overview, directly on your smartphone.
For small-business owners, freelancers and self-employed people who want a simple, legally sound way to write invoices.
Yes, day-to-day invoicing works fully offline and all data is stored locally on your device. Only the purchase and the subscription's periodic check need a brief internet connection.
Free use includes one invoice per calendar month. Premium costs €4.99 per month or €39.99 per year and unlocks unlimited invoices and the ZUGFeRD export.
Yes. Without Premium, you can finalize one invoice per calendar month — great for trying it out. Invoices you've already created stay fully usable regardless.
Germany's §19 UStG lets small businesses skip charging VAT. HEPLANO Rechnung fully supports this, including the legally required notice on the invoice, and prevents an invoice from being marked as both small-business and VAT-liable at the same time.
ZUGFeRD (also known as Factur-X) is an e-invoice format that embeds a structured XML file directly inside a normal PDF — many business customers and public buyers now require it. HEPLANO Rechnung generates ZUGFeRD invoices in the EN16931 profile.
The app covers the core legal requirements: mandatory fields, gapless invoice numbers, invoices that become immutable once finalized. It doesn't replace tax advice for the final assessment of your individual situation.
Only while it's still a draft. A finalized invoice is deliberately immutable (as required by German record-keeping rules, GoBD) — corrections happen via a cancellation invoice.
It negates the amounts of the original invoice, gets its own invoice number, and stays traceable alongside the original — the intended way to correct a finalized invoice.
Only drafts, at any time. Finalized invoices stay in place for the ten-year statutory retention period; after that, you can permanently delete them from Settings via a dedicated, manually triggered action with confirmation.
A breakdown of VAT by rate for a chosen period, on either an accrual or cash basis — the basis for your VAT advance return. It doesn't replace tax advice.
Accrual basis counts the invoice date; cash basis counts the date payment actually arrives. Which method applies to you is determined by your tax office.
Yes, for one-off customers — subject to the usual limits for small-value invoices under §33 UStDV, and without ZUGFeRD export, since a buyer address is mandatory for that.
Yes, in the item catalog — set them up once, reuse them in every new invoice.
Yes, including an automatically derived payment status (open, partially paid, overdue).
Entirely locally on your device, in an encrypted database. There's no automatic cloud upload.
The local database is encrypted, and the app can additionally be locked with biometrics or a device code.
You can create an encrypted backup with a password you choose and restore it later. Without that password, restoring isn't possible — not even for us.
Then the backup can no longer be decrypted. For security reasons there's no recovery option without the password — so keep it somewhere safe.
No. Premium is tied to your Google account, no separate HEPLANO account is needed.
You can reactivate your Premium entitlement on the new device via "Restore purchases". Invoice and customer data can be transferred via backup.
Yes — as a regular PDF, or with Premium also as a ZUGFeRD file; both can be printed or shared directly from the app.
Yes. Under "Export invoices" in Settings you choose a period; all finalized invoices in it are exported as PDF — optionally also as a ZUGFeRD file — into your chosen folder, e.g. to hand over to your tax advisor or for your income statement (EÜR). Nothing is deleted from the app in the process.
You set a storage folder on your device once in Settings; the app then exports there directly, without showing the picker again each time.
The interface is currently available in German, English and Polish. Invoice content itself is currently written in German.
HEPLANO Rechnung launches for Android. An iOS version is planned for later.
