In brief: Accountants see late payment differently from everyone else: not as one bad debtor, but as the same cash flow leak repeating across dozens of client businesses. That vantage point makes accountancy firms the natural channel for fixing it, by helping clients move repeat invoices onto Direct Debit collection connected to the accounting software the firm already manages.

This guide covers why it works, which clients to start with, how to raise it, and what it does for the firm itself.

The problem accountants see on repeat

Every management accounts meeting tells the same story from a different chair: profitable on paper, tight in the bank, and an aged debtors report doing the explaining. UK research puts around £26 billion in late payments outstanding at any time, with affected businesses owed an average of roughly £17,000 and losing about 86 hours a year to chasing.

Advisers can and do help with credit control policies, reminder templates and forecasting. But those tools all share a limit: they prompt the client's customer to act. The payment still depends on someone else's to do list. The causes are unpacked in why clients pay invoices late.

Why Direct Debit is the adviser grade answer

Direct Debit flips the direction of the payment. The client's customer approves a mandate once; each invoice then supplies its own amount and due date and is collected through Bacs with advance notice. For the payer, the Direct Debit Guarantee provides stronger error protection than any other method. For the client, receipts move from hoped for to scheduled.

The part that matters to accountants specifically: when collection is driven by the invoice in Xero, QuickBooks or Sage, the data stays clean. Amounts are never retyped, payments reconcile back to the invoice automatically, and the debtor book the firm reports on starts shrinking instead of ageing.

Which clients benefit first

Not every client is a day one candidate. The strongest profiles:

  • Repeat invoicing with variable amounts: agencies, IT support, cleaning, facilities, bookkeeping, trades on maintenance contracts. The variable amount is exactly what standing orders cannot handle.
  • Retainer plus extras billing: a fixed base with monthly variations, the classic reconciliation headache.
  • High debtor days against their sector: the clients whose management accounts conversations keep circling back to cash.
  • Owner operators drowning in admin: where the founder is the credit controller, every reclaimed hour is a selling point.

Poor first candidates: businesses with genuinely one off anonymous customers, or clients whose problem is disputes rather than collection. Fit matters more than enthusiasm.

How to raise it with clients

The conversation lands best inside work the firm already does:

  1. At management accounts or year end: "Your debtor days are 52 against a sector norm nearer 30. Here is what that gap costs you, and here is how we would close it." The costing method is in the true cost of late payments.
  2. At onboarding: new clients arriving on cloud accounting can start with collection switched on, so chasing never becomes a habit.
  3. At software review: when the firm is already optimising the client's Xero or QuickBooks setup, collection is the natural next module.

Frame it around the client's customers too: no payment dates to remember, notice before every collection, and Guarantee protection. Most resistance dissolves when the client realises their customers are being offered convenience, not risk.

What the firm gains

  • Advisory value that shows up in the bank: debtor days falling is the most visible advisory win a firm can deliver, and it renews itself every month.
  • Cleaner books, less write off work: automatic reconciliation means fewer unmatched receipts and suspense entries at year end.
  • Healthier clients: businesses that collect on time survive shocks better, and surviving clients remain clients.
  • A repeatable playbook: once the firm has moved three clients, the fourth takes an hour of partner time, not a project.

How NRTH works with accountancy firms

NRTH partners with UK accountancy firms through the NRTH Ambassador Program. The firm introduces clients where the fit is right; NRTH handles the mandate journey, collection scheduling, failure reporting and reconciliation back into the client's accounting platform. The firm stays in the advisory seat with visibility across its client base, without becoming a payments processor itself.

Setup for a client follows the standard route described in setting up Direct Debit for a business: verification, software connection, mandate invitations, then collections against invoice due dates.

Frequently asked questions

Can accountants set up Direct Debit on behalf of clients?

The client business is the collecting organisation and completes its own verification, but the firm can drive the process: identifying candidates, connecting the accounting platform, shaping the customer communication and monitoring results.

Does this work for clients with variable monthly invoices?

Yes, that is the core use case. One mandate supports variable collections, with the invoice supplying each amount and the customer receiving advance notice.

What does the firm earn from recommending it?

Partner arrangements vary; the durable value is advisory: measurable debtor day improvements, cleaner reconciliation and stickier clients. Speak to NRTH about the Ambassador Program for specifics.

Which clients should a firm not move to Direct Debit?

Businesses with one off anonymous customers, or where the real issue is disputed work rather than slow payment. Direct Debit fixes collection friction, not contract problems.

Accountants cannot make their clients' customers pay. They can change the system so payment stops depending on them.
