Overview
KashFlow is an online bookkeeping application aimed at UK sole traders, contractors, and small limited companies. Duane Jackson founded it in 2006, and IRIS Software Group has owned it since 2013. It handles quotes and invoices, including repeat invoices and purchases. It also covers bank feeds and reconciliation, VAT management with online submission to HMRC, purchases and expenses, mileage tracking, multi-currency, stock control, and more than 50 reports with a customisable dashboard. Payroll for up to five employees is included in both plans. Customers can pay invoices through KashFlow Payments and IRIS Pay. Pricing has two tiers. Starter costs £13.50 a month and is limited to one user, 10 invoices, and 25 bank transactions to reconcile. Business costs £27.50 a month and is multi-user with unlimited invoices and reconciliation. New customers have been offered heavy introductory discounts, such as 90% off for six months on monthly billing or reduced first-year annual prices. Accountants can use KashFlow Connect for free to work with client books. There is an apps directory covering CRM, payments, and e-commerce, including Salesforce, Zoho, PayPal, Stripe, Square, and Magento, as well as a SOAP API. The main limitation is depth and reputation. Reviewers describe it as too basic for growing or mid-sized companies, hard to customise, and backed by weak customer service. Its Trustpilot and app store ratings are poor, and the product is built almost entirely for the UK market.

The low-cost single-user Starter plan targets sole traders and contractors, but it caps invoices at 10.
Less suited
