IRIS KashFlow: An Overview

IRIS KashFlow is online accounting software aimed at small businesses, contractors, and accountants in the UK. It combines basic bookkeeping, invoicing, bank reconciliation, VAT submission, payroll support, and payment collection in a single cloud application so you can manage accounts from any device.

Compared with QuickBooks Online and Xero, KashFlow focuses on UK-specific compliance such as Making Tax Digital for VAT and Income Tax Self Assessment, and it integrates payments and simple payroll workflows within the same product. Compared with FreeAgent, KashFlow tends to market more heavily to accountants and bookkeeping practices with a brandable partner program and accountant-centric controls.

What KashFlow does particularly well is provide a straightforward, UK-compliant bookkeeping experience with invoice branding, automatic VAT submission to HMRC, and optional payments to speed up cash collection. It is best suited for sole traders, micro businesses, and small limited companies that want simple accounting plus easy accountant collaboration.

How IRIS KashFlow Works

KashFlow runs entirely in the browser, with data stored in the cloud so users can access accounts from desktop or mobile. Users set up a business profile, connect bank feeds, create products or services, then raise quotes and convert them to invoices for customers.

Bank reconciliation is handled by matching imported bank transactions to invoices, bills, and expenses; the system learns common matches to speed future reconciliation. VAT returns can be prepared and submitted directly to HMRC using the platform’s MTD-capable submission flow, and you can add payroll or use KashFlow Payments to accept card payments from invoices.

Accountants can manage multiple client accounts from a branded partner interface, invite clients to share access, and apply standard bookkeeping processes across client books. Practical workflows include raising recurring invoices, auto-sending payment reminders, and exporting data for HMRC or year-end accounts.

IRIS KashFlow features

KashFlow groups core small-business accounting into a few focused areas: invoicing and payments, bank reconciliation, VAT and tax submissions, basic payroll services, reporting, and accountant collaboration. Recent product messaging emphasizes payments integration and Making Tax Digital compliance.

Let’s talk IRIS KashFlow’s Features

Invoicing and quotes

Create branded quotes, convert them to invoices, and attach a “pay now” option so customers can pay online. Templates are simple to customize and automatic reminders can be scheduled to chase late payments.

Bank reconciliation and bank feeds

Link bank accounts to import statements and match transactions to invoices, bills, or expenses; the matching rules reduce repetitive manual matching and speed up month-end workflows.

VAT & Making Tax Digital

VAT is calculated within the system and can be submitted to HMRC using the platform’s MTD flow, simplifying quarterly returns and reducing manual spreadsheet work. For background on the UK requirement see the Making Tax Digital guidance.

Payments and cash collection

KashFlow includes integrations for card and online payments so you can add payment buttons to invoices and reconcile payments automatically, helping improve cashflow and reduce time spent chasing debtors.

Reporting and dashboards

Standard reports cover profit and loss, balance sheet, VAT reports, debtor and creditor positions, and simple stock control; reports are suitable for bookkeeping reviews and preparing management information.

Payroll and payroll outsourcing

KashFlow supports payroll processing or can integrate with managed payroll services; there are guides and options for outsourcing if you prefer a hands-off approach for employee pay and deductions.

Accountant partner tools

Accountant-focused controls let practices brand the interface for clients, manage multiple client ledgers, and share bookkeeping responsibilities while retaining oversight from a partner dashboard.

With these capabilities, the biggest practical benefit is reducing bookkeeping friction for UK businesses while keeping tax filings and payment collection connected to day-to-day accounting activity.
