FreeAgent Invoice Reminder Alternative (UK): 5 Tools That Chase Harder Without Leaving FreeAgent

FreeAgent's automatic invoice reminders are fine for the client who simply forgot. They are not built for the client who read your invoice, filed it under "later", and is now 40 days past due. If you've gone looking for a FreeAgent invoice reminder alternative in the UK, it's almost certainly because the built-in sequence ran out and the invoice is still sitting there.

The good news: you don't need to leave FreeAgent. It's a great set of books, especially if you're getting it free through a NatWest, RBS, Ulster Bank or Mettle business account. What you need is something that sits on top of it and does the chasing FreeAgent stops doing.

Where FreeAgent's automatic invoice reminders hit their limits

Let's be fair to FreeAgent first. Under Settings you can switch on reminders before the due date, on the due date, and after it, plus an automatic thank-you email when the invoice is marked paid. You can turn reminders off for individual contacts or invoices. For a lot of sole traders, that's genuinely enough.

Here's where it stops being enough:

• The sequence is short and then it ends. A handful of touchpoints and FreeAgent goes quiet. Nothing fires at day 45, day 60, or day 90, which is exactly when you need something firing.
• One tone for everyone. The templates are set per business, not per client. Your friendly repeat customer and the agency that's paid late four times running get the same email.
• No statutory interest. FreeAgent won't calculate or add late payment interest for you. If you want to charge it, you're adding a line manually or raising a separate invoice, and none of the reminder emails mention it.
• No SMS, no escalation logic. It can't text, can't notice a client has opened the reminder three times without paying, and can't hand a stubborn invoice off to a firmer step.
• Emails go out via FreeAgent's servers. They're sent on your behalf rather than from your own inbox, so replies and deliverability aren't quite the same as a normal email from you.

None of that is a bug. FreeAgent is accounting software with a reminder feature bolted on. FreeAgent late payment chasing was never meant to be the whole system.

The UK detail FreeAgent leaves out: statutory interest

If your client is a business (not a consumer), the Late Payment of Commercial Debts (Interest) Act 1998 gives you the right to charge interest at 8% above the Bank of England base rate, plus a fixed compensation fee per invoice: £40 under £1,000, £70 from £1,000 to £9,999.99, and £100 at £10,000 or more. You don't need it in your contract. It applies by default unless you agreed a different "substantial remedy".

The reference rate is the base rate on 31 December for invoices falling due between January and June, and 30 June for invoices due July to December. Our late fee calculator will do the maths if you'd rather not.

The point for this post: mentioning it in a reminder changes behaviour. Here's the paragraph I'd add from the second overdue reminder onward:

Under the Late Payment of Commercial Debts (Interest) Act 1998, this invoice now attracts statutory interest at 8% above the Bank of England base rate, plus fixed compensation of £[40/70/100]. We'd much rather not add this. If payment reaches us by [date], we'll waive it.

That last sentence is doing the heavy lifting. It's firm, it's legal, and it gives them a way out. FreeAgent's templates can hold that text, but only in a fixed slot in a fixed sequence. The tools below let you time it.

5 FreeAgent invoice reminder alternatives for UK businesses

All of these keep FreeAgent as your system of record. You keep raising invoices there, reconciling your bank feed there, and filing your VAT return and Self Assessment from there.

1. Saldetto: the lightweight chaser that keeps going

Saldetto is built for exactly the gap above: a reminder sequence that escalates in tone and doesn't stop at reminder three. You set the cadence once (say, day 3, 7, 14, 21, 30, 45), write the templates from gentle to final notice, and it runs. Emails send from your own address, so replies land in your inbox and it reads as you, not a robot.

Good for: sole traders and small businesses with 5 to 50 open invoices a month who want statutory interest wording to appear at the right stage, automatically, without building a workflow.

Limits: it's a chasing tool, not credit control. No credit risk scores, no debtor insurance, no calling service.

Pricing: flat monthly plan with a free trial, no per-contact fees. Details at saldetto.com/pricing.

2. Satago: credit control with a native FreeAgent connection

Satago is UK-based and one of the few credit control platforms that connects directly to FreeAgent. It pulls your invoices and contacts, runs automated chasing, and layers on credit risk data so you can see which clients are likely to pay late before you invoice them.

Good for: small businesses that want the risk intelligence as much as the reminders, or who might eventually want invoice finance against outstanding invoices (Satago offers it).

Limits: it's more than most freelancers need, and the pricing has shifted over the years as the product has leaned towards finance. Check the current plans before assuming the free tier still covers you.

3. Chaser: the full UK credit control desk

Chaser is the heavyweight in UK invoice chasing. Multi-step email and SMS sequences, an escalation to a human chasing team you can pay for, payment portal, the lot. It's well regarded and very much built for the UK market.

Good for: businesses with a bookkeeper or finance person and enough invoices that a dedicated credit control workflow pays for itself.

Limits: no native FreeAgent integration as far as their integration list goes. You'd be working from CSV exports, which undermines the "set it and forget it" idea. Pricing starts in the tens of pounds per month and climbs quickly with volume. Overkill for a solo operation.

4. GoCardless through FreeAgent: stop chasing the recurring ones

This one is a sidestep rather than a chaser. FreeAgent integrates natively with GoCardless, so for any client you invoice regularly (retainers, monthly fees, recurring services) you can put them on Direct Debit and pull the payment on the due date.

Good for: anyone whose late-payer problem is mostly the same three retainer clients every month. Direct Debit removes the decision from their hands.

Limits: only works for clients willing to sign a mandate, which one-off project clients usually won't. GoCardless takes a small per-transaction fee. And it does nothing for the invoices that are already overdue.

5. Zapier or Make with FreeAgent: the DIY route

FreeAgent has a Zapier integration, so you can trigger on invoice events and send your own follow-ups from Gmail or Outlook. Pair it with a Google Sheet tracking days overdue and you can build a rough escalation ladder for free-ish.

Good for: people who enjoy building automations and have a very small number of invoices.

Limits: you're maintaining it forever. Every edge case (partial payment, credit note, client asks for a pause) is your problem, and the "reminders stopped working and I didn't notice for six weeks" failure mode is real. If you've read our late payment email toolkit and thought "I'll just wire these into Zapier", ask yourself honestly how many hours you'll spend on it.

What to do when reminders run out

Whichever tool you pick, a chaser only takes you so far. For UK B2B debts, the step after your final notice is a letter before action, which a solicitor service will send on headed paper for a few pounds plus VAT. It's astonishing how many invoices get paid within days of one arriving.

After that it's Money Claim Online for debts under £10,000, which you can file yourself. Our late payment policy template gives you a one-page document to send new clients so none of this is a surprise to them later.

Verdict

If you're a UK sole trader or small business and FreeAgent's built-in reminders have let you down, the honest breakdown is:

• Most freelancers and small businesses: Saldetto. It fills the exact gap, keeps FreeAgent as your books, and the statutory interest wording lands at the stage you choose.
• You want risk data and a native FreeAgent sync: Satago.
• You have a finance person and real volume: Chaser, accepting the CSV workflow.
• Your problem is the same recurring clients every month: GoCardless via FreeAgent, then chase the rest with one of the above.
• You like building things and have five invoices a month: Zapier.

The wrong answer is switching accounting software to get better reminders. Every UK bookkeeping tool has roughly the same reminder feature and the same limits. A FreeAgent invoice reminder alternative should sit alongside FreeAgent, not replace it, and the best one is the one that's still sending on day 60 when you've stopped thinking about it.
