Accounts Receivable Software UK 2026: Chaser, Satago, GoCardless, Tesorio

Accounts receivable management is the operational discipline most directly connected to business survival: a profitable business with poor receivables management runs out of cash. UK B2B payment terms average 37 days from invoice date against a contracted average of 28 days, according to Xero's Small Business Insights data -- meaning the typical UK business is always owed more than it is contractually entitled to wait for. Accounts receivable software addresses this through automated payment reminders, direct debit collection, real-time debtor dashboards, and integration with accounting platforms to eliminate manual reconciliation. This guide covers the leading UK platforms, their regulatory context, and what businesses at different scales should prioritise.

The Late Payment Problem and UK Legal Framework

Late payment costs UK small businesses an estimated £1.6 billion annually in financing costs, according to the Federation of Small Businesses. The legislative framework intended to address this is the Late Payment of Commercial Debts (Interest) Act 1998, which gives B2B creditors the right to charge statutory interest at 8% above the Bank of England base rate on overdue invoices, plus fixed compensation (£40 for invoices under £1,000, £70 for £1,000-£9,999, £100 for £10,000+). These rights apply automatically -- no contract clause is required -- but they must be actively claimed.

Accounts receivable software that tracks days overdue and calculates statutory interest automatically provides the data foundation to exercise Late Payment Act rights consistently rather than selectively. Few UK businesses currently claim statutory interest on every overdue invoice -- the administrative overhead of calculating and issuing interest charges manually is a practical barrier that AR software removes.

For consumer debts (where the debtor is an individual rather than a business), the regulatory framework shifts significantly. The FCA's debt collection guidance under CONC 7 imposes specific rules on contact frequency, communication methods, and treatment of debtors in financial difficulty. Automated payment chasing systems must be configured to comply with CONC 7 if any debtors are consumers -- in practice, this means configurable contact frequency limits and immediate escalation pathways for debtors who indicate financial hardship.

UK GDPR and Debtor Data Management

Accounts receivable software processes personal data (debtor names, contact details, payment history) and is therefore subject to the UK GDPR as implemented by the UK Information Commissioner's Office. The lawful basis for processing debtor data is typically legitimate interests (recovering money owed) or performance of a contract. Automated payment chasing systems must not contact debtors in ways that could constitute harassment under the Protection from Harassment Act 1997 -- excessive contact frequency or aggressive language in automated reminders creates both regulatory and reputational risk.

Data retention is a specific UK GDPR consideration for AR systems. HMRC requires financial records to be retained for six years; the ICO's guidance states that personal data should not be retained beyond the period necessary for the original purpose. These requirements point in different directions for debtor records -- the solution is to retain financial transaction data for six years while anonymising or deleting personal contact details after the debt is resolved and any dispute limitation period has expired.

UK Accounts Receivable Software Platforms Compared

Chaser is the most widely used standalone AR automation platform among UK SMEs using Xero or QuickBooks. Its automated chasing sequences (configurable email and SMS reminders at defined intervals before and after due date) reduce average debtor days by a median of 16 days according to Chaser's own published data. The GoCardless integration allows direct debit mandates to be set up directly from the Chaser interface, combining chasing and collection in one workflow.

GoCardless approaches AR from the collection side rather than the chasing side. By establishing direct debit mandates with customers, it removes the payment friction that causes many late payments -- customers pay automatically on the due date rather than needing to action a payment manually. For subscription businesses, SaaS companies, and any UK B2B business with recurring invoices, GoCardless's variable direct debit product (which allows different amounts each cycle) is a more effective solution than automated chasing alone.

Satago combines AR automation with access to invoice finance from its own lending book, allowing businesses to chase debtors automatically while simultaneously drawing against overdue invoices. This integrated model suits businesses that need both better collection processes and occasional cash flow bridging without managing two separate provider relationships.

Automated Payment Chasing: Sequence Design and Compliance

The effectiveness of automated AR chasing depends almost entirely on sequence design -- the timing, tone, and escalation path of reminder communications. The most effective sequences for UK B2B businesses follow a pattern: a friendly pre-due reminder (3-5 days before due date), a polite due-date notification, a firm first overdue reminder (7 days), a more direct second reminder with Late Payment Act interest notification (14 days), and a final notice before escalation (30 days).

Tone calibration matters more than most businesses recognise. Automated reminders that read as generic spam are ignored; reminders that appear personalised (using the debtor contact's name, referencing the specific invoice number and original due date) achieve significantly higher response rates. Chaser and Satago both support personalisation variables within automated templates.

Escalation pathways must be configured before go-live, not improvised when a debtor reaches 60+ days. The options at escalation are: internal credit controller intervention, formal Letter Before Action (LBA) under the Pre-Action Protocol for Debt Claims, referral to a debt collection agency, or County Court claim via HMRC's Money Claims Online service. AR software that integrates with a debt collection agency API (some platforms offer this) automates the handoff at a defined overdue threshold without requiring manual action.

Integration With Accounting Software: Where Time Savings Are Realised

The primary productivity benefit of AR software for most UK businesses is not the chasing automation -- it is the elimination of manual reconciliation between the AR system and the accounting platform. Without integration, payment allocation (matching received payments to the correct invoices in Xero or QuickBooks) is a time-consuming daily task prone to error. With a native integration, payments collected through GoCardless or Stripe are automatically matched to the corresponding invoice in the accounting platform, reducing reconciliation to exception management.

For businesses using Xero, the native Chaser, GoCardless, and Satago integrations sync invoice status bidirectionally -- when a payment is received and matched in Xero, the AR platform automatically updates the invoice as paid and removes it from the chasing queue. This eliminates the embarrassing scenario of continuing to chase a customer who has already paid, which damages the commercial relationship and is a common failure mode of manual AR processes.

The ICAEW's guidance on accounts receivable management for UK businesses emphasises that AR software should be evaluated on integration quality first, feature breadth second. A well-integrated simple platform outperforms a feature-rich platform with poor accounting integration in every practical measure of time saved and error rate.

FAQ

Can I charge statutory interest on every overdue invoice automatically?

Yes. The Late Payment of Commercial Debts (Interest) Act 1998 gives you the right to charge statutory interest at 8% above Bank of England base rate on every overdue B2B invoice without a specific contract clause. AR software can calculate this automatically. In practice, most businesses exercise this right selectively -- applying it consistently to persistent late payers but waiving it for occasional late payments from otherwise reliable customers to preserve the commercial relationship.

Is automated debt chasing subject to FCA regulation?

For B2B debts, automated chasing is not directly regulated by the FCA. For consumer debts, the FCA's debt collection rules under CONC 7 apply and impose specific requirements on contact frequency, communication content, and handling of debtors in financial difficulty. If any of your debtors are individuals rather than businesses, your AR system's chasing sequences must be configured to comply with CONC 7, including mandatory pauses if a debtor indicates financial hardship.

How does UK GDPR affect automated payment reminders?

Automated payment reminders process personal data (debtor contact details) and must have a lawful basis under UK GDPR -- typically legitimate interests in recovering money owed. Your privacy notice should disclose that automated payment reminders are sent. Debtors have a right to object to processing under the legitimate interests basis; an effective objection would require manual rather than automated communication. The ICO's accountability framework guidance provides practical steps for documenting your lawful basis.

What is the most effective way to reduce debtor days for a UK B2B business?

The single most effective intervention is collecting by direct debit rather than invoice. GoCardless variable direct debit removes the manual payment action from the customer entirely, reducing late payment to failed collections (typically 2-5% of mandates) rather than deliberate non-payment. For businesses that cannot mandate direct debit collection, a pre-due reminder sent 5 days before the due date consistently reduces late payment rates more than any post-due reminder, because it prompts the debtor to action payment before the deadline rather than after.

When should a UK business use a debt collection agency rather than AR software?

AR software is effective for debts under 60-90 days old where the debtor is solvent but slow to pay. Above 90 days, the probability of voluntary payment without legal escalation drops significantly. A debt collection agency (DCA) is appropriate when: the debtor is unresponsive to all automated and manual contact, the debt exceeds £500 (making DCA fees proportionate to recovery), and the debtor does not appear to be in formal insolvency proceedings. DCAs charge 10-25% of recovered debt on a no-collection-no-fee basis. For debts above £10,000, a solicitor's Letter Before Action followed by County Court proceedings is often more cost-effective than a DCA.
