What Is a Recurring Invoice?
A recurring invoice is an invoice issued on a regular schedule — monthly, quarterly, or weekly — for ongoing services or subscriptions. The line items and amounts are typically the same each period, making it easy to bill retainer clients and subscription customers.
Common use cases:
- Monthly retainer fees (consultants, agencies, virtual assistants)
- SaaS or software subscription billing
- Ongoing maintenance contracts (IT support, landscaping, cleaning)
- Membership fees
- Monthly content creation or social media management
What to Include on a Recurring Invoice
Recurring invoices should clearly indicate the billing period so clients can match the invoice to the correct period:
- Billing period — e.g., "Services for May 2025" or "Retainer: 1 May – 31 May 2025"
- Service description — specific enough that the client knows what they are paying for
- Fixed retainer amount or usage-based fees
- Any variable charges — additional hours, expenses, or overage fees listed as separate line items
- Running invoice number — include the period in the number (e.g., INV-2025-05) for easy filing
- Payment due date — consistent billing dates help clients plan cash flow
Setting Up a Consistent Billing Cycle
Consistent billing builds professional relationships and makes cash flow predictable for both parties. Best practices:
- Bill on the same date each month — the 1st or last day of the month is most common
- Agree the billing date in the contract — avoid disputes about when invoices are due
- Use a fixed due date — "Net 14 from invoice date" is clearer than "due in 2 weeks"
- Send a reminder before the invoice — for large retainers, a brief heads-up reduces payment delays
- Duplicate last month's invoice in invoicePrivate — update the dates and period, keeping all other details consistent
Frequently Asked Questions
Should I use one invoice per month or a single ongoing invoice?
Issue a separate invoice for each billing period. This creates a clear record for both parties, makes it easier to track payments, and is required for proper VAT accounting in most jurisdictions. Referencing the billing period in the invoice number (e.g., INV-2025-05) makes filing straightforward.
How do I handle scope changes on a retainer?
Keep the retainer fee as a fixed line item and add any additional work as separate line items with a description. This makes the invoice transparent and avoids confusion about what the retainer covers. Discuss scope changes with the client before adding them to the invoice.
Can I include both a fixed retainer and variable hours on the same invoice?
Yes. Use the retainer fee as the first line item, then list additional hours as separate line items (hours × rate). invoicePrivate supports multiple line items with different pricing models on the same invoice.
Do retainer invoices need to show VAT every month?
Yes, if you are VAT-registered. Each recurring invoice is a separate tax event. Show the VAT calculation on each invoice and ensure the due date is within the correct VAT period for reporting purposes.
