Crowd investing solutions

Crowd investing: One company, many investors

As a contemporary, digital form of corporate financing, crowd investing makes it possible to raise debt capital outside the institutional sector via an online platform or a dedicated issuing site. With secupay's services, you as an issuer or platform operator offer potential investors a convenient way to participate in promising financing projects. Funds provided are managed through insolvency-proof escrow accounts in compliance with ZAG and disbursed according to project specifications.

Automated interest and principal payments via API or eTerminal



Start financing projects quickly and easily

Make it easier for start-ups and companies to launch their financing project with secupay's convenient onboarding. Contract conclusion and identification can be done directly on your platform page.

Payment or repayment

Disbursement or reversal after completion of the financing phase

Once the agreed disbursement requirements have been met and the target amount has been collected in full, the sum must be disbursed promptly to the initiator of the respective financing project. secupay supports the disbursement in one sum or also in several partial amounts. Commissions and fees for stakeholders, for example, your share as a platform operator, are automatically settled and paid thanks to payment splitting. And if a project is not fully financed, secupay pays back the existing funds to the investors.

B2B Lösungen

Interest & principal payments

Reliable service until the last instalment

If a crowd-investing project is successful and the financing amount is paid out to the initiator, the interest and redemption phase follows. With secupay, you offer users of your platform reliable service right up to the last instalment. We support you in ensuring that interest and redemption payments are always received in the correct amount and on time in the investors' accounts. Automate payment flows via API or use the convenient secuOffice portal to instruct payments individually or as a package.

Automatisierung der Investitionsprozesse

Einfache Abführung der Kapitalertragsteuer (KapESt) durch secupay

Mit dem Jahressteuergesetz 2022 ergeben sich für Crowd-Investment-Plattformen Änderungen hinsichtlich des Handlings der Kapitalertragsteuer: Seit dem Jahreswechsel führen Zahlungsdienstleister wie secupay diese inkl. Solidaritätszuschlag und ggf. Kirchensteuer im Rahmen der gesetzlichen Verpflichtung auf Zinszahlungen ans Finanzamt ab.

Data portal

All projects at a glance

In the secuoffice online portal, you will find all relevant information such as incoming payments, account balances, disbursement criteria or budget billing schedules clearly prepared for each project on your platform. Role-based access rights give users insight into their data and enable them to independently carry out transactions such as cancellations, interest or redemption payments. Via API, the data from the portal can be conveniently exported to other systems for further processing. Alternatively, you can also integrate display and evaluation functions from secuoffice there.

Smart API for crowdfunding

API integration

Secupay's convenient crowdfunding services can be seamlessly and almost intuitively integrated into your platform via API. We provide developers with our descriptive online documentation with case studies and libraries. For all technical questions, our support team will assist you quickly and competently.
