What Letting Agencies Should Look for in Inventory Software

Most letting agencies are still using Word templates or basic PDF tools for check-in and check-out reports. Some have graduated to specialist inventory software. A smaller number have moved to platforms built specifically around evidence integrity.

The differences between these approaches are significant — and they matter most in the moment you'd least want them to matter: a contested deposit dispute.

If you're evaluating inventory software for your agency, or just want to audit the tools you're already using, here are the criteria that actually count.

1. Immutability: Can Files Be Edited After Upload?

This is the single most important question. If a photo or report can be altered after it's been uploaded and signed, your evidence is fundamentally weak — regardless of what it shows.

Ask your current provider: can a file be modified once it's been stored? Can a landlord upload a photo, delete it, and replace it with a different one? Can the text of a report be changed after a tenant has signed?

If the answer to any of these is yes — or if you don't know the answer — that's a problem. Evidence that could theoretically have been tampered with will be treated as such by a deposit scheme adjudicator.

Look for: immutable storage at the infrastructure level (Object Lock or equivalent), not just a "lock" feature in the UI that could be bypassed.

2. Dual Sign-Off: Does the Tenant Sign Digitally?

A report that only the landlord has signed is a one-sided document. The tenant can dispute it entirely — claim they never saw it, that conditions were different, or that their signature was added without their knowledge.

For a report to be evidentially robust, the tenant needs to sign the same record that gets stored. And the sign-off needs to happen on the platform, not via a paper document that gets scanned and uploaded (which creates the same alteration problem as above).

Ask: does the tenant sign in the system itself? Is the signature timestamp recorded? If the tenant refuses to sign, does the system log that refusal?

3. Metadata Preservation: Does It Capture When and Where Photos Were Taken?

Every smartphone photo contains hidden data: the precise date and time it was taken, the device model, and often the GPS coordinates of where it was taken. This EXIF data is the first thing a serious adjudicator looks at when assessing photographic evidence.

Many platforms strip this data — intentionally or through compression. If your inventory software removes EXIF metadata, you're losing one of your strongest pieces of corroborating evidence.

Look for: platforms that read EXIF data at upload, store it independently, and cross-reference it with the reported inspection date and location. Bonus: flagging if metadata doesn't match (a photo taken before the tenancy, or taken at a different address).

4. Shareable Records: Can Both Parties Access the Same Record?

An inventory stored only on the landlord's or agent's system is a one-sided record, even if the tenant signed it. For genuine transparency — and for the credibility that comes with it — both parties should be able to access the same version of the same record at any time.

This matters in disputes where the tenant claims the version they saw was different from the version submitted to the deposit scheme. If both parties have read-only access to the same stored record, that argument is eliminated.

5. Export for Disputes: Can You Generate a Professional Submission?

When a dispute goes to TDS, DPS, or mydeposits, you need to submit evidence in a format the scheme can review. That typically means a PDF report with photographs, condition descriptions, and timestamps.

Good inventory software generates this automatically. You shouldn't be manually assembling evidence from screenshots, email attachments, and phone photos when a dispute arises — that's exactly when you're least likely to do it well.

Ask: what does the dispute export look like? Does it include timestamps, signatures, and metadata? Is it formatted professionally enough to stand up to scrutiny?

6. Tenant Experience: Is It Free and Easy for Tenants?

The best inventory software in the world fails if tenants won't use it. If signing a check-in report requires a tenant to download an app, create an account, and pay for a subscription, your sign-off rate will be low.

Tenants should be able to sign reports via a simple link — no app, no payment, minimal friction. If the tenant experience is cumbersome, landlords and agents will give up on getting the signature, and you're back to one-sided reports.

Ask: what does the tenant need to do to sign off on a report? How many steps does it take? Is there any cost to the tenant?

7. Mobile-Friendly: Is It Designed for On-Site Use?

Check-ins don't happen at a desk. They happen in an empty flat, often with a tenant present, with a phone in one hand and a clipboard (metaphorically) in the other.

Inventory software that requires you to take photos on your phone and then upload them to a desktop app later introduces a gap — time between photo and upload during which things can change. Software that works natively on mobile, captures photos directly in the app, and uploads immediately closes that gap.

Ask: is there a proper mobile app? Or is it a desktop-first tool with a basic mobile browser version?

A Quick Comparison of Approaches

Word/PDF templates: Free, flexible, but no immutability, no metadata preservation, and difficult to get genuinely dual-signed. Adequate for simple cases; weak in contested disputes.

Specialist inventory software (e.g. InventoryBase, Inventory Hive): Better than PDFs — professional formatting, some digital sign-off capability. Varies significantly on immutability and metadata handling. Check the specifics.

Evidence-focused platforms (e.g. Fairhold): Built around tamper-proof storage from the ground up. Immutable file storage, EXIF capture, cryptographic hashing, dual sign-off in-platform. Higher standard of evidence but also higher setup requirement.

The right choice depends on your agency's size, case volume, and how often you face contested disputes. If your disputes are rare and straightforward, a decent specialist tool may be sufficient. If you manage large portfolios or frequently deal with difficult tenants, the quality of your evidence infrastructure directly affects your liability.

Evaluating Your Current Process

Before purchasing anything, audit what you have:

• Can your current reports be altered after signing?
• Does your photo evidence include verifiable timestamps?
• Do tenants sign the same record you'd submit to a dispute scheme?
• Can both parties access the stored report at any time?
• If a dispute arises tomorrow, how long would it take you to compile the submission?

Most agencies find at least two or three of these questions uncomfortable. That discomfort is worth paying attention to — it's where the risk lives.
