Recurring invoices let you automate billing for clients you invoice on a regular schedule — monthly retainers, quarterly subscriptions, annual contracts, and more. Once a schedule is active, Aczen Bilz generates the invoice automatically on each run date so you never miss a billing cycle.

​
Set up a recurring invoice schedule

1

Open Recurring Invoices

In the left sidebar, click Recurring Invoices. You will see a summary of all your active and paused schedules, along with the total number of invoices generated so far.
2

Create a new schedule

Click New Schedule in the top-right corner to open the setup dialog.
3

Select a client

Use the Client selector to choose the client this schedule is for. Their name, email, and GSTIN are pulled from your contacts automatically.
4

Set the invoice amount and tax rate

Enter the base Amount (before GST) and choose the applicable GST Rate (0%, 5%, 12%, 18%, or 28%). The total due on each generated invoice will be this amount plus GST.
5

Choose a frequency

Select how often the invoice should be generated:
The Custom Cron option accepts standard five-field cron syntax: minute hour day month weekday. Use a tool like crontab.guru if you need help building an expression.
6

Add optional notes

Enter a note that will appear on every generated invoice — for example, “Monthly retainer — June 2025” or “Q2 support contract”. This helps your client identify the billing period.
7

Save the schedule

Click Create Schedule. The schedule is saved in an active state, and the Next Run date is calculated automatically based on your chosen frequency.

​
How invoices are generated

On each scheduled run date, Aczen Bilz creates a new invoice in your account with:
  • A sequential invoice number (e.g., INV-2025-0042)
  • Today’s date as the invoice date and a due date 30 days later
  • The client details and amount from the schedule
  • A note indicating it was auto-generated from a recurring invoice
The generated invoice appears in your Invoices list with Pending status, ready to be sent to the client.
If you need to generate an invoice immediately — for example, to bill a client before the next scheduled run — click the Play button on any schedule in the table. This creates an invoice right away and advances the next run date.

​
Manage your schedules

All your recurring schedules are listed in the Schedules table with the client name, amount, frequency, next run date, and a count of how many invoices have been generated so far.
Toggle the switch in the Status column to the off position. The schedule is paused and no new invoices will be generated until you re-enable it. Pausing does not delete the schedule or its history.
Toggle the switch in the Status column back to the on position. The schedule resumes from the next calculated run date based on the original frequency.
Click the red Trash icon to permanently delete a schedule. This stops all future invoice generation for that schedule. Invoices that were already generated are not affected.
Deleting a schedule is permanent. If you only want to stop billing temporarily, use the pause toggle instead.

​
Dashboard overview

The three summary cards at the top of the Recurring Invoices page give you a quick view of:
  • Total Schedules — the total number of schedules you have set up (active and paused)
  • Active — schedules that are currently running and will generate invoices automatically
  • Invoices Generated — the cumulative count of invoices produced across all schedules
