Every decision was made by a practising UK accountant who needed it to actually work. Here's what makes AccountFlow different.
Not a tech firm guessing what you need. Built by a practising UK accountant — so MTD ITSA, CIS, self assessment, and limited company workflows are first-class features, not afterthoughts.
VAT returns, Annual Accounts, Confirmation Statements, Payroll & P11D, CIS monthly returns, and MTD ITSA — all tracked in one practice-wide calendar with overdue alerts and automated client reminders.
Every AccountFlow plan includes Capstone Timer — built in, no add-on required. Know exactly where your hours go, report by client and user, and export directly to your invoicing workflow.
Pre-written templates for every document request and deadline reminder — bank statements, VAT documentation, year-end packs, MTD ITSA notices, and payroll reminders — sent automatically at the right time.
Role-based access for Admin, Manager, and Staff. Client-user assignments, staff invitation with secure onboarding, and a 7-year audit trail for every action taken across your practice.
Practice compliance score, deadline pipeline by status, team workload, and billable hours by client and user. Reports built for how practices are actually managed — not generic dashboard widgets.
Limited Companies, Sole Traders, Partnerships, LLPs, and CIS Contractors — each with the correct fields, filing deadlines, and compliance workflows for their entity type. No forcing your clients into the wrong box.
7-year audit log retention, practice-level data isolation, bcrypt password hashing, JWT authentication, CSP headers, parameterised SQL, and TLS 1.2+ in transit. Security built in from the ground up, not bolted on.
Stripe-powered subscription management, invoice tracking, and a customer billing portal. Upgrade, downgrade, or cancel at any time — no contracts, no cancellation fees, no locked-in pricing surprises.
AccountFlow is built with security at the architecture level — not bolted on after the fact. Here's exactly how we protect your practice and your clients.
