Recurring Invoices: How to Automate Monthly Billing for Clients

If you bill the same client every month, a retainer, a subscription service, or ongoing maintenance work, manually creating and sending that invoice each month is a drain on your time. It's not difficult work, but it's repetitive, easy to forget, and the kind of task that quietly costs you an hour or two every month across all your recurring clients.

Recurring invoices solve this by automating the entire process. Set it up once, and the invoice generates and sends itself on schedule going forward.

This post covers how recurring invoicing works, who benefits most from it, and how to set it up using Built For Small Business.

What is a recurring invoice?

A recurring invoice is an invoice template that automatically generates and sends on a set schedule, weekly, monthly, or yearly, without you needing to manually create it each time.

Instead of opening your invoicing software on the 1st of every month, filling in the same client details and line items, and sending it manually, you set the invoice up once with a recurring schedule. From that point forward, it generates and sends automatically based on the interval you choose.

Who benefits from recurring invoices?

Recurring invoicing makes the most sense if you have:

Retainer clients, agencies, consultants, and freelancers who charge a fixed monthly fee for ongoing work benefit enormously. The invoice amount doesn't change month to month, so automation removes the manual step entirely.

Subscription-based services, if you offer a service at a fixed monthly or annual price, recurring invoices keep billing consistent without you needing to remember dates.

Maintenance and support contracts — web developers, IT support providers, and similar service businesses often have clients on monthly support packages. Recurring invoicing keeps that billing on schedule automatically.

Rent or equipment hire — businesses that charge recurring fees for space, equipment, or ongoing access to a service.

If your invoicing varies significantly month to month, with different line items, different amounts, and project-based work, recurring invoicing is less useful since you'd need to create a new invoice manually anyway. In that case, duplicating a previous invoice as a starting point is faster.

The benefits of automating monthly billing

You stop forgetting to invoice.

This sounds small until it happens to you. A busy month passes, you forget to send the invoice for a retainer client, and suddenly you're a month behind on cash flow for no reason other than an admin oversight. Recurring invoices remove this risk entirely; the invoice goes out on schedule whether you remember or not.

You get paid more consistently.

When invoices go out on the same date every month, clients build a predictable payment rhythm. Late payments often happen because an invoice arrives at an inconsistent time and gets lost in someone's inbox. Consistency helps both sides.

You save real time

If you have five retainer clients and each invoice takes ten minutes to create and send manually, that's nearly an hour every month spent on a task that adds no value to your business. Over a year, that's close to twelve hours, a full working day, spent on something that could run itself.

You reduce errors

Manual invoicing means manual data entry, and manual data entry means occasional mistakes, wrong amounts, wrong client details, and wrong dates. A recurring invoice template is set up correctly once and then runs identically every time.

How to set up recurring invoices in BFSB

Setting up a recurring invoice in BFSB takes the same amount of time as creating a single invoice; the only difference is selecting the recurring option.

Step 1 — Create your invoice as normal

Add your client, line items, pricing, and any notes or terms exactly as you would for a one-off invoice.

Step 2 — Enable the recurring toggle

When creating the invoice, switch on the "Recurring" option. This reveals additional fields for setting up the schedule.

Step 3 — Choose your interval

Select how often the invoice should generate — daily, weekly, monthly, or yearly. For most retainer arrangements, monthly is the standard choice.

Step 4 — Set the number of occurrences

Decide how many times the invoice should repeat. If you're not sure how long the arrangement will run, you can set a higher number and cancel the recurring schedule later if needed.

Step 5 — Save and let it run

Once saved, BFSB handles the rest. The invoice is generated and is recorded against your client automatically based on the schedule you set.

What happens to recurring invoices after they're created

Each time a recurring invoice is generated, it behaves exactly like a manually created invoice; it appears in your invoices list, contributes to your tax year totals, and can be tracked for payment status.

If a client pays via the Stripe payment link on the invoice, that payment is recorded the same way as any other invoice payment, and your profit and loss reporting reflects it automatically.

When to stop or adjust a recurring invoice

Client relationships change, a retainer might end, a price might increase, or the scope of work might shift. When this happens, you can pause or cancel the recurring schedule from your invoices dashboard.

If the price changes but the client relationship continues, it's usually simplest to cancel the existing recurring schedule and create a new one with the updated amount, rather than editing an active recurring invoice mid-cycle.

A note on communication

Automation works best when clients know what to expect. If you're switching an existing client from manual to recurring invoicing, a short heads up, "you'll now receive your invoice automatically on the 1st of each month", avoids any confusion when the invoice arrives without the usual personal email alongside it.

The bigger picture

Recurring invoices are a small feature with a disproportionate impact on how much time you spend on admin. For anyone with retainer clients, subscription services, or recurring contracts, this single setting can save hours every month, time that's far better spent on the work that actually grows your business.

Frequently asked questions

Can I edit a recurring invoice after it's been set up? You can pause or cancel a recurring invoice schedule at any time. To change the amount or line items, it's recommended to cancel the existing schedule and create a new recurring invoice with the updated details.

Will my client be notified when a recurring invoice is generated? Yes, recurring invoices are sent to your client the same way a manually created invoice would be, using the contact details on file for that client.

Can recurring invoices include VAT? Yes, VAT is applied the same way as on standard invoices. If your business is VAT registered, the rate you select will apply to each generated invoice.

Is recurring invoicing available on the free plan? Yes, recurring invoicing is included as part of BFSB's free Foundation plan, alongside standard invoicing, expense tracking, and payroll.

What happens if I forget to cancel a recurring invoice? The invoice will continue to generate based on the schedule and number of occurrences you originally set. If you set a fixed number of occurrences, it will stop automatically once that number is reached.
