What Dext Pricing Actually Costs UK Accountancy Practices
Most UK practice owners know roughly what they pay for Dext. They see the monthly direct debit, wince slightly, and move on. What they rarely do is stop and calculate what that spend is preventing them from doing.
As of June 2026, Dext charges UK practices £391 per month for 50 clients, £894.15 per month for 150 clients, and £1,541.10 per month for 300 clients, all ex-VAT, on their per-client model. These are not small figures. And they're not fixed: because Dext prices per client, your bill rises with every client you add.
For context, Receiptflow charges £150 per month for up to 50 clients, £275 per month for up to 150 clients, and £500 per month for up to 300 clients - flat tiers, no per-client creep.
The annual gap between those two pricing structures is:
- 50 clients: £2,892 per year
- 150 clients: £7,429.80 per year
- 300 clients: £12,493.20 per year
Those numbers are not rounding errors. They're real budget lines. And the question worth asking isn't just "is Dext worth the premium?" It's "what would that money actually do for my practice if I redirected it?"
Why Most Practices Never Ask That Question
The per-client pricing model is designed, intentionally or not, to make cost increases feel gradual. You don't get a single invoice that says "your Dext spend increased by £3,000 this year." You get twelve monthly debits, each slightly higher than the last as your client list grows.
In August 2023, Dext eliminated unlimited practice plans in the UK and moved entirely to per-client pricing. Practices that had been on flat fees saw their bills increase by 200 to 400 per cent at renewal, as widely reported on AccountingWEB at the time. The per-client model has been the norm ever since.
The result is what you might call overhead creep. The kind that compounds quietly and rarely triggers a formal review the way a large one-off cost would. A new piece of office equipment prompts a conversation. A slow monthly direct debit increase doesn't.
Until you run the numbers.
