You probably have some questions about our rebrand, we hope to answer them below.

We are excited to introduce Frisbii - a new unified brand that brings together billwerk+, an expert in cross-industry subscription management and payments in Germany and Denmark; Plenigo, a specialist in digital and print media subscriptions in Germany; and Sofacto, a French provider of a subscription management app for Salesforce. By combining our strengths under one brand, we are creating a powerful solution for businesses managing recurring revenue.

While our name and look are evolving, our core mission remains the same: helping businesses simplify recurring revenue management through seamless subscriptions, billing, and payments.

What does this mean for you?

Same platform, new name: The Platform remains the same, but you’ll see our new name and branding in emails, dashboards, and communication and a new login domain.
No immediate action needed: Your contracts, integrations, and billing setups continue as usual.
Continued support: Our customer success and technical support teams are still here to help - just under a new brand.
Stay tuned: Over the coming months, we’ll communicate any specific actions we might need you to take as we progress with the rebrand.

Frequently Asked Questions - FAQs

Why did billwerk+, plenigo, and Sofacto rebrand to Frisbii?

Over the years, we’ve expanded our capabilities and customer base across Europe. Bringing everything under one brand allows us to provide a clearer, stronger, and more unified experience.

What changes with the rebrand?

Our name and branding have changed to Frisbii.
Our dashboard styling and UI will gradually evolve to match our new look.
Our website and emails will reflect our new identity.
No immediate changes to pricing, contracts, or support.
Some help videos and documentation will still show billwerk+ temporarily while we update content. Don’t worry it's all part of the transition.

Will my contract change?

No, your contract remains valid under the same terms. But when it's time for renewal, you will sign a new Frisbii contract.

Will my invoices and billing statements be affected?

Our legal entities are changing so invoices will now be issued with the new Frisbii logo from:

billwerk+ Germany GmbH is becoming Frisbii Germany GmbH
billwerk+ Denmark A/S is becoming Frisbii Denmark A/S
billwerk+ France SAS is becoming Frisbii France SAS
Poland to follow.

All other billing details, including bank accounts, payment information and addresses, remain unchanged.

Will the product change?

In the coming weeks, you will notice changes in colors, fonts, and logos in your merchant interface, however, all functionalities will remain the same. The product you know will not change, but changes will be introduced to continue the migration to the new brand. E.g. URLs.

New Domains

We are introducing the following new domains to our systems, together with new ssl certificates, which will include the additional domains:

Service	System	Old Domain	New, Additional Domain	Comment
API, Admin Interface	Production	app.billwerk.com	app.frisbii-transform.com
Selfservice, Production System	Production	selfservice.billwerk.com	selfservice.frisbii-transform.com	Only relevant, if you use our selfservice resources (Hosted Iframe, SubscriptionJS)

API, Admin Interface	Sandbox	sandbox.billwerk.com	sandbox.frisbii-transform.com
Selfservice, Production System	Sandbox	selfservice.sandbox.billwerk.com	selfservice.frisbii-transform.com	Only relevant, if you use our selfservice resources (Hosted Iframe, SubscriptionJS)

No worries - the old domains will remain available for at least one more year, and we will notify you well in advance of any changes.

Some areas may also refer to or display the billwerk+ Transform name temporarily - don’t worry, it’s all part of the transition!

Will the way I log in or access my account change?

You can continue logging in with your existing credentials as usual. We will introduce the new login URL under the new brand but will also include a redirect from the existing URL.

Current URL: https://app.billwerk.com/#/login

New URL: http://app.frisbii-transform.com/#/login

Will my API access change?

Not at the moment; all existing API endpoints remain operational. We will introduce our endpoints under the new brand and phase out the old endpoints over time, but we will provide more information on this with a long migration lead time. We will also be updating the API documentation to reflect the new brand.

Do I need to update my integrations?

No, your current integrations will continue working as before. We will introduce endpoints under the new brand, but the phasing out of the current endpoints will have a long lead time.

Will there be any changes to the sender email addresses for system notifications?

Currently, system notifications are sent from notification@mail.billwerk.com (for production) and notification@mail.sandbox.billwerk.com (for sandbox).

Starting March 20, emails will come from our new Frisbii addresses:

Production: notification@mail.frisbii.com
Sandbox: notification@mail.sandbox.frisbii.com

This only applies to you, if you have NOT configured a custom sender domain.

Is there any downtime or migration required?

No, there is no downtime or migration required due to the rebrand. All services continue as usual.

What about the help center, video tutorials and documentation?

We are in the process of updating materials, but some videos, guides, and tooltips may still reference billwerk+ Transform for a period. Rest assured that they remain accurate and valid.

We will migrate all help center information and API documentation to a new help center and phase out the current sites over the coming months, with a lead time.

We will communicate this change before we remove the old ones and redirect you to the new help center.

Will support channels change?

We’re transitioning to support@frisbii.com as our new support email.

Our existing support emails will remain active for some time, and we’ll provide advance notice before they are phased out.

We are updating our phone system, but existing numbers are still active.
