Recurring Invoices: A Complete UK Guide

What recurring invoices are and who benefits

A recurring invoice is an invoice template that your software issues automatically on a set schedule, so you don't rebuild the same document every cycle. The line items, client, VAT rates and payment terms stay the same; only the invoice number and dates change each time.

They earn their keep wherever you bill the same amount on a predictable rhythm:

• Retainers — agencies, consultants, bookkeepers and solicitors charging a fixed monthly fee.
• Subscriptions — software, equipment hire, managed IT, or any "x per month" product.
• Memberships — gyms, clubs, trade bodies, co-working spaces.
• Maintenance contracts — cleaning rounds, gardening, servicing, support cover.

If your work is genuinely one-off or the amount changes every time, a recurring invoice helps less. But for fixed ongoing fees it removes the most common reason invoices go out late: someone forgetting to send them. Invoify handles the scheduling for you with recurring invoices, and the step-by-step setup lives in the help guide.

Choosing a billing frequency

Pick the frequency that matches how the service is consumed and how your client's finance team prefers to pay. Going more often than the work warrants just creates admin on both sides; going less often hurts your cash flow.

Monthly is the norm for UK B2B services. Annual billing reduces admin and can improve retention if you offer a discount for paying up front, but a single missed annual payment leaves a bigger hole than a missed monthly one, so chase it promptly.

Automating delivery and collecting payment

Setting a frequency is only half the job. The other half is making sure the invoice goes out and the money comes in without you touching either.

Delivery. Turn on auto-send so each invoice emails to the client the moment it's generated. Set realistic payment terms (Net 14 or Net 30 are standard in the UK) and a clear reference the client's accounts team can quote back to you. Build the underlying document once in the invoice editor and the schedule reuses it.

Collection. An invoice asks for payment; it doesn't take it. For predictable recurring amounts, pair the invoice with Direct Debit so the cash is pulled automatically on or just after the due date. In the UK most small businesses run Direct Debit through a provider such as GoCardless rather than setting up a bank mandate directly, because the provider handles the mandate, the Bacs submission and the failed-payment retries.

The clean pattern is: recurring invoice goes out as the formal record and VAT document, Direct Debit collects against it on the due date. The client gets a proper invoice for their own bookkeeping, and you stop spending the last week of every month doing collections by hand.

Dunning and automatic reminders

Dunning is the structured follow-up process for invoices that haven't been paid. Even with Direct Debit, payments fail — expired cards, insufficient funds, cancelled mandates — so you need a sequence that nudges late payers without you watching a spreadsheet.

A sensible reminder ladder for recurring invoices:

1. A polite reminder a few days before the due date (optional, but it cuts late payments).
2. A reminder on the due date.
3. A firmer follow-up 7 days past due.
4. A final notice at 14 days past due, mentioning your right to charge statutory late-payment interest.

Invoify can run this ladder for you with payment reminders, and you can tune the timings in the reminder setup guide. For B2B debts you have a statutory backstop: under the Late Payment of Commercial Debts (Interest) Act 1998 you can charge interest at the Bank of England base rate plus 8%, plus fixed compensation per invoice.

The base rate used is the rate in force on 30 June (for debts due July–December) or 31 December (for debts due January–June) — always check the live Bank of England base rate before you calculate, rather than relying on a number you remember.

Proration when starting mid-cycle

When a client joins partway through a billing period, you usually prorate: charge for the days they actually used rather than the full period. This keeps everyone on the same billing date and avoids arguments about paying for time before the service started.

A simple worked example for a £300/month retainer where the client signs up on the 16th of a 30-day month:

• Daily rate: £300 ÷ 30 = £10 per day
• Days remaining (16th to 30th inclusive): 15 days
• First (partial) invoice: 15 × £10 = £150
• From the next cycle onward: the full £300 on the 1st

Decide your convention up front — whole-month rounding versus exact daily proration, and whether you count the start day — and apply it consistently. If you're VAT registered, the prorated amount is the net figure you then apply VAT to, the same as any other invoice. See how UK VAT rates work if you're unsure which rate applies to your service.

The VAT tax point for continuous supplies

Recurring billing usually counts as a continuous supply of services for VAT, and that changes when the tax point falls. For continuous supplies the tax point (the date the VAT is due, which we call the supply date in the app) is normally the earlier of the date you issue the VAT invoice or the date you receive payment.

In practice this means each recurring invoice creates its own tax point on the day it's issued, so the VAT goes on the return for that period. Two things follow:

• Use the rate in force at the tax point. If HMRC changes a VAT rate, update your recurring template so future invoices use the new rate. Past invoices keep the rate that applied when they were issued. The current rates of VAT on different goods and services are on GOV.UK.
• Keep digital records. Under Making Tax Digital for VAT, all VAT-registered businesses must keep digital records and file via compatible software — recurring invoices that live in proper software already satisfy this.

Each invoice must still show everything a VAT invoice requires: your name, address and VAT number, the customer's details, a description, the VAT rate per item, and the totals ex-VAT, VAT and inc-VAT. If you're not VAT registered, the invoicing rules are lighter but you still need a unique number, both parties' details, a description and the amount due. Not sure whether you should be charging VAT at all? Check the registration threshold — £90,000 of taxable turnover in any rolling 12-month period.

Common mistakes to avoid

A few recurring-invoice errors come up again and again:

• Breaking the number sequence. Every issued invoice needs a unique sequential number. Let the software auto-increment via your invoice numbering scheme rather than typing numbers by hand.
• Forgetting to stop a schedule. When a contract ends, end the recurring schedule the same day. Billing a former client is awkward to unwind and damages trust.
• Leaving a stale VAT rate. If a rate changes or your supply changes (for example moving between standard and reduced), the template keeps using the old rate until you update it.
• No payment method behind the invoice. Sending invoices on a schedule but collecting them manually defeats the point. Wire up Direct Debit and reminders so collection is automatic too.
• Ignoring failed Direct Debits. A failed collection is not a paid invoice. Make sure your dunning sequence catches failures and re-presents or chases them.
• Not reviewing prices. Revisit recurring rates at least annually so inflation doesn't quietly erode your margin.
