Unit Manager Pro vs Stora: Comparing the Best UK Self-Storage Software

Stora and Unit Manager Pro are both UK-built self-storage platforms aimed at independent operators. They share a modern UX, online booking, and a tenant portal — but their approach to billing automation, payment resilience and pricing structure diverges sharply. If you're comparing the two, this is where the decision is made.

What both platforms get right

• UK-native — GBP invoicing, UK support, and GDPR-ready hosting
• Website + online booking — built-in, SEO-friendly, with real-time availability
• Tenant portal — payments, documents, and support tickets in one place
• GoCardless Direct Debit — both support BACS for lower-fee recurring rent

Where Unit Manager Pro pulls ahead: payment automation

Card backup if Direct Debit fails

Direct Debit fails roughly 3% of the time — usually when a tenant switches banks or has insufficient funds. Without a backup, that's hours of manual chasing per failure. Unit Manager Pro's billing engine automatically retries the payment on the tenant's saved card when Direct Debit bounces. The failure becomes invisible: the tenant sees a cleared invoice, and you see zero admin.

Automated rent increases

Both platforms support scheduled price changes, but Unit Manager Pro ties rent reviews directly into the invoice generation and tenant notification flow — no manual CSV uploads or spreadsheet checks required. Set the rule once, and the system applies it, notifies the tenant, and updates their recurring payment amount without interruption.

Dunning and late-fee automation

Unit Manager Pro runs a full dunning workflow out of the box: soft reminder, late fee, second reminder, card retry, and owner alert — all on configurable timelines. Stora handles retries, but the deeper multi-stage dunning engine is a point of difference for operators who want to run entirely hands-off.

Where Stora is strong

• Website design — Stora's template library is larger and more visually polished for operators who prioritise brand aesthetics
• Multi-site portfolio view — cleaner dashboard for owners with 5+ locations
• Community and events — strong operator network, annual summit, and peer learning

The pricing reality

Stora uses a per-unit model that scales with occupancy. For smaller facilities this is attractive; past 200 units the monthly cost climbs steeply. Unit Manager Pro uses flat-tier pricing that caps your software cost as you grow, making it predictable for operators planning to scale past 150 units.

Verdict: which platform for which operator?

Choose Stora if you run 1-2 smaller sites, value design-led websites above all else, and your payment failure volume is low enough that manual follow-up is manageable.

Choose Unit Manager Pro if you want payment automation that truly runs without you — card backup on Direct Debit failure, scheduled rent increases, and full dunning — at a predictable price as you scale.
