Kolleno now lets you cap how many invoices are automatically charged per customer in a single auto-charge run. This protects you from bulk payment failures — for example, when a customer has a large number of outstanding invoices, the system previously attempted to charge all of them at once, which could result in failed payments, a deactivated mandate, and invoices incorrectly marked as paid.
Where to find it
The setting lives in Settings → Payments. Look for the "Auto-charge invoice limit" section.
How it works
By default, there is no limit — Kolleno charges all outstanding invoices per customer in each auto-charge run, which is the existing behaviour.
When you enable the cap, you configure two things:
Number of invoices — the maximum number of invoices Kolleno will charge per customer in a single run. Must be at least 1.
Invoice ordering — which invoices are prioritised when the limit is hit:
Oldest first — charges invoices in order from oldest to newest by creation date
Newest first — charges invoices in order from newest to oldest by creation date
Once saved, this limit applies globally across your account.
Which flows does this affect?
The cap applies to automatic charging scenarios, across all payment methods (Direct Debit and card):
Scheduled auto-charge — runs daily. Kolleno picks up invoices within a 30-day window for auto-charge. Within that window, invoices due today are always charged first. If today's due invoices don't fill the limit, the remaining slots are filled by other invoices in the window, ordered according to your ordering preference.
Workflow auto-charge retries — the limit applies per customer per workflow run. There is no today-priority logic here, as the workflow has already pre-selected the invoices to retry.
The cap does not apply to manual bulk-charge actions — if you explicitly select invoices in the UI and trigger a charge, all selected invoices are processed regardless of this setting.
Removing the limit
To remove the cap and revert to charging all outstanding invoices, toggle the setting off and save.
Things to note
The invoice count and ordering preference must both be set together — you cannot save one without the other.
The limit applies per customer per run, not across your entire customer base.
This setting does not affect one-off manual payment collection.
