Billing placeholders

• Any member with permission to create or edit products, contracts, or invoices.
• Billing permissions are granted in Team permissions. See Members and Teams permissions.

Placeholder	What it inserts
{{invoice_previous_period}}	Previous billing period (for example “December 2025”)
{{invoice_period}}	Current billing period (for example “January 2026”)
{{invoice_next_period}}	Next billing period (for example “February 2026”)
{{quantity_as_time}}	Billed quantity displayed as time (for example “2h 30min”)
{{quantity_as_number}}	Billed quantity displayed as a number (for example “2.5”)
{{client_primary_user}}	The client’s primary assigned team member name

One more placeholder is available on the Elite plan: {{payment_link}}. Add it to the Invoice description on a client’s contract settings and the invoice PDF prints a pay link. Two things set it apart from the placeholders above. Uku fills it in when the PDF is rendered, not when the invoice is generated. And it prints nothing until you connect a payment method. See Payment links.

For prepayment invoices, {{invoice_next_period}} is especially useful — it automatically shows the upcoming billing period on the invoice.

Placeholders can be added in the Product, Contract, or Invoice view.

1. Open the Product, Contract row, or Invoice line you want to edit.
2. In the description field, type the placeholder exactly as shown in the table above — for example {{invoice_period}}.
3. Save the product or contract row.
4. When Uku generates the invoice, the placeholder is automatically replaced with the real value.

If a product description contains:

Accounting services for {{invoice_period}}

The generated invoice line displays:

Accounting services for January 2026

Check the placeholder syntax again. The format must be exactly {{placeholder_name}}, with no extra spaces inside the braces. Copy the placeholder from the table above and paste it in, so the spelling is right.

Verify that the correct placeholder is used. {{invoice_period}} shows the current billing period; {{invoice_previous_period}} and {{invoice_next_period}} show the adjacent periods. Also confirm that the contract’s billing period is configured correctly.

{{quantity_as_time}} and {{quantity_as_number}} pull data from tracked time entries. If no time has been logged against the relevant tasks for that billing period, the value is zero.
