KashFlow Reviews & Product Details

I have been with Kashflow about 11 years and initially the system worked, it was sold to me at a networking event but over the years it hasn't kept pace with other vendors, the only thing I like is the dashboard has stayed the same, Review collected by and hosted on G2.com.

IRIS Pay has some serious operational flaws that create unnecessary risk for any business relying on it.

Invoice branding is broken

Even after updating our account to a Limited Company and changing all settings in the dashboard, invoices are still being issued in the original account holder’s name. This isn’t cosmetic—it’s a compliance and credibility issue. Clients see the wrong entity, which undermines trust and creates avoidable confusion.

Direct Debit logic is fundamentally flawed

If you cancel or disable an invoice, you would reasonably expect any associated Direct Debit to stop. It doesn’t.

IRIS Pay continues to collect unless you manually cancel the collection in a separate system.

That means:

You cancel a service

The client still gets charged

You then have to deal with the fallout

Worse, you can’t cancel collections within 3 days of the due date, so even if you catch it late, you’re stuck.

This isn’t a minor UX issue—it’s a structural problem. The system separates invoicing from payment execution without enforcing logical safeguards. The burden is entirely on the user to prevent incorrect billing.

The result?

Unnecessary admin, reputational damage, and frustrated customers asking why they’ve been charged for cancelled services.

For a payments platform, that’s not acceptable. Review collected by and hosted on G2.com.

Kashflow is quick and straightforward to use once you know how. With a little training, which was usefully available through Kashflow, we were on our way. It is so useful to create and monitor invoices, email customers directly, and create a detailed log of our accounts. Review collected by and hosted on G2.com.

Automatic emails to clients with receipts following paying an invoice would be useful. We have suggested this as feedback. Review collected by and hosted on G2.com.

Invoice and email templates, plus the ability to schedule recurring invoices. It is very intuitive, even if you've not done accounts before. Review collected by and hosted on G2.com.

It is a little expensive, in my opinion, but I can't be sure the cheaper alternatives would be as good. Review collected by and hosted on G2.com.

Easy customer and supplier creation process, built-in credit control feature that allowed to set up messages and send them automatically on chosen days of the month. Review collected by and hosted on G2.com.

Discrepancies in values on different reports based on the same information. Too simple for medium-size business, no general customers/sales dashboard, no bulk payments feature. Problems with built-in bank reconciliation, Audit trail report only showing one part of the transaction and missing the other side (double-entry). Review collected by and hosted on G2.com.

A cloud based accounting software for small businesses. The best thing about this accounting software is, it is user friendly it can work like any other accounting software, available at economical cost in comparison of other brands. Review collected by and hosted on G2.com.

There is a big issue at the time of reporting by the software. Usually it happens when you file the return through this software instead of using government utilities. Therefore, its output requires correction otherwise it will incur a heavy penalty if even a single figure goes wrong. Review collected by and hosted on G2.com.

Intuitive, good pricing and cloud-based Review collected by and hosted on G2.com.

Not familiar for some accountants, AND not as integrated as XERO with some APIS Review collected by and hosted on G2.com.

The simplicity and the layout. Also the fact that it offers separate sections for receipts and suppliers, while most online invoicing software completely skips receipts. Over the years the price has remained between £12 and £18, with a few ups and downs, so overall very affordable for the offering. Invoice generation is simple, although you can only choose from a few templates. Recurring invoicing is also included in the price. It also integrates with PayPal, so any purchases made that way can be automatically pulled into KashFlow, and with a click of a button you can get the expenses receipts created. Over the 10 years that I've used it for, there were only a few minor outages, that very always very quickly resolved. Can't really comment on support as never needed it.

No customisation and very little improvement over the years in terms of useful features. Exporting Receipts in PDF would also be nice, but at the moment it's only an Excel export. Fully functional mobile app would be welcome. Currently it's more of a web-app. An option to link purchase to an invoice would be great, to work out an actual profit per invoice / client. Currently there's no way of doing that, so a profit per customer is really revenue per customer as it excludes the cost of parts supplier etc. Review collected by and hosted on G2.com.
