Invoicing Overview

FlowForth includes a full invoicing system that lets you generate invoices from completed activities, manage VAT, send invoices electronically, and track payments — all from within the app.

How Invoicing Works

The invoicing workflow in FlowForth follows these steps:

  1. Complete activities — Activities are performed and tracked in the system.
  2. Create an invoice — Select a client and choose which completed activities to include.
  3. Review and edit — Adjust prices, add discounts, configure VAT, and add manual line items as needed.
  4. Send the invoice — Send via Peppol e-invoicing or email. The invoice is frozen for compliance once sent.
  5. Track status — Monitor whether invoices are delivered and accepted.

Invoice Statuses

Invoices progress through the following statuses:

StatusDescription
DraftInvoice is being prepared — fully editable
SentInvoice has been sent to the client — calculations are frozen
DeliveredDelivery confirmed (Peppol tracking)
AcceptedClient has accepted the invoice
CancelledInvoice has been cancelled — cannot be changed
tip

Only Draft invoices can be edited or deleted. Once an invoice is sent, its values are frozen for EU compliance and audit purposes.
