Payment reminders & blocking

Send automatic reminder e-mails for overdue invoices and, optionally, deactivate relations that leave an invoice unpaid — with automatic re-activation on payment.

Last updated 2026-09-08

For organisations where relations pay after receiving their invoice, Aerolync can follow up overdue invoices automatically: first with a reminder e-mail, and optionally by deactivating the relation until the invoice is paid. Both functions are off by default and are configured in Config → Settings → Finance → Payment reminders & blocking.

Whether an invoice counts as paid follows the payment status that is derived from the relation's account — so the mechanism also behaves correctly for prepaid relations, whose invoices are covered by their balance immediately.


Payment reminders

Setting Description
Send automatic payment reminders Master switch.
Days after due date When the reminder is sent; 0 sends it on the due date itself.
Reminder e-mail text Your own message to the relation.

The e-mail consists of your text, followed by a fixed block with the invoice details — number, invoice date, due date, invoice amount, open amount and the payment reference — and the invoice PDF as attachment. Each invoice receives at most one reminder, and only while its payment status is still open or partial: an invoice that is paid before the threshold never triggers a mail.

Blocking on overdue invoices

Setting Description
Deactivate relation when an invoice remains unpaid Master switch.
Days after due date The blocking threshold (default 14 days).
Send an e-mail when the relation is deactivated Optional notification, with its own text field; same fixed invoice-details block and PDF attachment.

Blocking uses the relation's regular Active switch (Account tab): the relation loses access to the Pilot App and disappears from the active lists — the same effect as deactivating them manually.

Automatic re-activation: as soon as the overdue invoice is covered (payment received, FIFO or matched), the relation is re-activated automatically on the next daily run. Only relations that were deactivated by this mechanism are ever re-activated; manually deactivated relations are never touched.

Note

the account tab of an automatically blocked relation shows a red banner with the blocking date. An administrator can switch the relation back to active manually, but while the invoice remains unpaid the daily check will deactivate them again — register the payment (or disable blocking) to lift the block permanently.
