Late Fee Automation

The Smart Way to Improve Collections in Self-Storage

Late payments disrupt cashflow, add administrative burden and can strain customer relationships. For self-storage operators, late fees are designed to offset these costs and encourage timely payment. Yet, despite their usefulness, they are often applied inconsistently or overlooked entirely. This article explores what industry bodies advise on charging late fees to self-storage customers, then explains how Kinnovis helps operators establish fair policies and automate them with confidence.

What are Self-Storage Late Fees?

A late fee is a one-off charge added when a customer misses a payment deadline. The Self Storage Association UK (SSA UK) advises that such fees should be disclosed clearly in the storage agreement, applied only once per overdue bill, and set at a level that reflects the true administrative costs of chasing arrears. The aim is not to punish customers, but to recover genuine costs and encourage punctual payment.

Associations in Europe and further afield echo the same principles: transparency, proportionality and consistency. Customers should always know in advance what will be charged, the fee must be reasonable compared with the operator’s costs, and it should be applied in a predictable way.

Legal guidance in the UK and Europe

The framework for late fees is shaped by consumer protection law. In the UK, the Consumer Rights Act 2015 requires terms to be fair and transparent. Similar rules apply across the EU under the Unfair Contract Terms Directive. Both prohibit “disproportionately high” charges, which means operators must be able to justify the level of any late fee they set.

For business customers, the position is slightly different. The Late Payment of Commercial Debts Act 1998 allows statutory interest and recovery costs to be added, but only when the agreement does not already provide a fair alternative. VAT rules also come into play: while genuine interest is exempt, flat administrative fees are often taxable.

Finally, if a customer defaults entirely, operators in England and Wales may rely on the Torts (Interference with Goods) Act 1977 to sell goods after proper notice. This is a technical area, and advice is recommended for operators working in Scotland or cross-border in Europe.

The case for automation

Despite the clarity of industry and legal guidance, many operators still struggle to apply late fees consistently. Manual processes make it easy to forget grace periods, compound charges incorrectly or miss overdue invoices altogether. Others hesitate to enforce fees for fear of customer pushback, even when those fees are contractually justified.

Automating the process solves these challenges. By setting clear rules once, operators can ensure late fees are always applied at the right time, in the right way and with a transparent trail of communication to customers.

How Kinnovis helps

Kinnovis offers two features within our Manager software: Automated Late Fees for consistent, rules-based enforcement, and Manual Late Fees for case-by-case flexibility. Together, they give operators the balance of efficiency and discretion that sector bodies recommend.

Automated Late Fees

With Automated Late Fees, you define rules at each location and let the system handle the rest. Fees can be fixed amounts or percentages of the overdue invoice, with custom grace periods and minimum thresholds to prevent very small balances from being penalised. Operators can also create several “stages” of late fees, such as one charge after a week and a higher one after a month, allowing them to reflect the growing effort of chasing debts.

When a payment is missed, Kinnovis automatically generates a late fee invoice linked to the original overdue invoice. Customers receive clear labelling on what the fee relates to and an email notification that explains the charge and includes a payment link. Importantly, the system does not take payment automatically, ensuring compliance with regulations that require explicit consent for additional charges. Instead, the invoice is presented transparently, and operators retain the ability to void or credit the fee if discretion is appropriate.

Manual Late Fees

There will always be exceptions where rules cannot cover every scenario. Manual Late Fees allow operators to issue charges individually, even if automated late fees are turned off. This is useful for overdue invoices that predate automation, or when a different amount or percentage needs to be applied. In these cases, the operator can also choose to collect payment directly using the customer’s existing method, an option not available for automated fees.

Manual Late Fees appear alongside automated ones in both the manager dashboard and the customer portal, ensuring consistency and visibility across the system.

Striking the right balance

Automating late fees does not mean losing discretion. Kinnovis makes it simple to stop automated late fees on a particular invoice, for example, if there is a dispute or you wish to void the fee as a gesture of goodwill. This flexibility reflects the advice of associations that late fees should be applied with fairness and understanding.

The result is a policy that is firm but reasonable. Customers know what to expect, operators regain control of collections and compliance is maintained without increasing staff workload.

Putting policy into practice

To make the most of a late fee strategy, operators should publish their rules clearly in agreements and on their websites, keep the structure simple, and document how fees were calculated to demonstrate fairness. Training staff to explain the policy confidently and reviewing the results regularly helps ensure it works as intended.

With Kinnovis, these principles are easy to embed. Location-specific settings mean operators with facilities across different regions can adjust for local rules, while automated emails provide consistent communication. Manual tools remain available for special cases, giving operators both efficiency and control.

Conclusion

Self-Storage late fees are an accepted part of the industry, but they must be applied with care. Associations in the UK and Europe advise fairness, transparency and consistency, while regulators focus on consumer protection and clear communication.

For operators, the real challenge is implementing these rules without wasting time or risking mistakes. By combining Automated Late Fees with Manual Late Fees, Kinnovis makes it possible to improve collections, protect compliance and keep customers informed – all while reducing the burden on staff.
