Merchant cards, mobile payments, and William AI Guidance 2.0: September Apron product updates

Pay smarter, chase less, and get frontier AI on every plan.

Nobody wants to rush through important business payments, but having the option to speed things up and find what you need more easily is always a plus.

Starting today, you can pay bills on mobile while you're out and about, sort paid bills from unpaid ones at a glance, view card details in the web app, and more.

This month also sees the introduction of our most significant updates and improvements to William AI since its launch. Keep reading for more information on what this means for access to William AI, and how it affects the way we will price Apron going forward.

William AI Guidance 2.0 (and platform updates)
William has evolved from a simple assistant into a full digital team member embedded across your bookkeeping workflows. Here’s a snapshot of what’s new:

Free-form guidance: Write rules in plain English for categories, VAT, tracking, and auto-publishing just as you'd explain them to a colleague.

Proactive inbox suggestions: William spots repeating manual corrections and offers ready-made rules with one-click saving.

Referenced document context: Every suggestion links back to source documents so you can see the reasoning behind the rule.

Line-item precision & tracking prediction: Pre-fills tracking categories automatically and splits complex supermarket or multi-line invoices into distinct categories and tax rates.

Along with Guidance 2.0, William AI is now available to every Apron user, moving out of tier-restricted access to become part of our core Capture offering. To support this innovation, we’ve also updated our platform pricing structure (while locking in our £199 fee cap for our accountant and bookkeeper partners who reach Gold tier status by the 1st of December, 2026).
