Customer accounts and cash records, made simpler

Duppo is a workspace for customer and supplier accounts, cash movements and daily business records. It does not replace professional accounting advice or official filing systems.

Small businesses and independent professionals can organize their accounts and cash records. For example, Homeros Bilişim can follow customer movements and daily expenses in one place.

Create customers and suppliers and record amounts owed, amounts due, collections and payments under the relevant account.

Record dates, amounts, categories and descriptions in the Cashbook. Use the available filters to review the period you need.

Supported customer and cashbook reports can be exported as Excel files. Check the date range and filters before downloading.

Select a date range in the relevant account and prepare a PDF statement. Review the amounts and business details before sharing it.

Supported reports and documents can be shared through the existing email dialog. This depends on plan permission and working operator SMTP settings; a send record is not a delivery guarantee.

Links on supported screens open a prepared message in WhatsApp. You review the recipient and content and send it yourself; there is no automatic bulk sending.

Upload a file using the template, map the fields and approve the preview. Correct invalid rows before approval and avoid changing existing records without review.

Duppo’s web screens are available in phone and tablet browsers. Wide report tables may scroll sideways within their own area.

Session and permission checks restrict access; the portal exposes only shared documents. Server backups are managed by the operator. Automatic customer backups are not guaranteed; important operations require a verified backup.

Standard offers free everyday accounts, cashbook and basic tools. Premium adds customer modules. Check the current plan comparison; prices come from the authorized management source.

Accounts, cashbook, basic and advanced reports, invoices, payments, appointments, portal, file sharing, document email, invoice uploads, employees and support. Super Admin tools are separate from customer plans.

The invoice module prepares documents using your business details and exports PDF files. This does not imply an official electronic invoice or GİB integration; assess your legal requirements separately.

Payment plans offer in-app and optional email reminders. Email requires SMTP and a server scheduler (cron). Appointment reminders appear in the application notification panel.

Use the appointment calendar for dates, times and notes. Appointment reminders appear inside the application; they are not email or push notifications.

You can switch between Turkish, German and English. Check the selected language before creating new reports.

Start with Standard and explore Premium in the upgrade area when needed. Access continues until the end of the paid period after cancellation; changing plans does not delete records.

Use the password reset link on the sign-in screen and enter your account email. Check your inbox and spam folder; never share your password or verification code.

Start with the Help Centre and Pakize tour. Send an enquiry through Contact; the support request screen is also available according to your plan and portal access.
