For UK estate and letting agents, the best PropTech is the platform that closes your specific funnel leak, not the one with the longest feature list. Off-the-shelf systems (Reapit, Alto, Street, Dezrez, Jupix) cover the core agency workflow - listings, applicant matching, sales progression, lettings management - and suit most agencies from around £70 to over £2,000 per month depending on size. A bespoke build, typically from £15,000, wins when your process is a competitive edge an off-the-shelf system cannot model: a unique prospecting method, a multi-brand or hybrid sales-and-lettings operation, or deep integration between your CRM, portals, and accounting that no single product delivers. Most agents should buy; agents whose process is the product should build.
PropTech is not one decision. An estate or letting agency runs prospecting, valuations, listings, applicant matching, viewings, offers, sales progression, tenancy management, compliance, and accounts - and the question is which of those a packaged product handles well and which is where your agency actually wins or loses business. This guide covers the main off-the-shelf options, where they fit and where they break, and the honest test for when a bespoke build pays for itself.
PropTech for a UK agency has to cover the whole journey from prospecting to completion or tenancy, and the highest-impact part is the front of it: winning the instruction before the vendor or landlord calls three other agents. Software that only uploads to Rightmove and Zoopla is table stakes; software that helps you win the listing in the first place is where the commercial difference sits.
The capabilities that matter, roughly in order of commercial impact:
An agency that competes on a particular strength - say, a data-driven prospecting method, or a slick sales-progression experience - needs that strength reflected in the software. That is the part a packaged product often cannot match.
Off-the-shelf PropTech is mature in the UK, and for most agencies it is the right starting point. The main platforms differ by size of agency and by which part of the workflow they do best.
Reapit and Alto are end-to-end systems that scale from independent agents to large multi-branch networks, strong on sales, lettings, and reporting. Street is a modern CRM with integrated AI for listings, summaries, and call handling, suited to agencies that want a current, automation-led experience. Dezrez offers end-to-end control with built-in conveyancing and client accounting to speed completions. Jupix and similar mid-tier tools cover the core workflow at a lower price point, while entry tools start around £70 per month for smaller operations. Pricing across the market runs from roughly £70 per month at the entry level to over £2,000 per month for larger, full-feature deployments.
Where they fit: any agency whose process is broadly standard - prospect, list, match, progress, manage tenancies - is well served by one of these, and should buy rather than build. Where they break: when your agency's edge depends on a workflow the product does not model, when you are stitching together three tools because no single one fits, or when integration between CRM, portals, and accounts is manual and error-prone. At that point you are paying for a product and still doing the hard part by hand.
Building beats buying when your process is your product. The test is simple: if the way your agency prospects, progresses, or manages tenancies is a genuine competitive advantage that an off-the-shelf system forces you to abandon or work around, a bespoke build protects and automates that advantage. If your process is standard, buy - a custom build there is wasted money.
The common triggers for building: a multi-brand or hybrid sales-and-lettings operation that no single product handles cleanly; a proprietary prospecting or valuation method you want automated rather than manual; deep integration needs between your CRM, the portals, your accounting, and tools like proptech for AML or referencing that the packaged products do not connect; or a scale where per-branch, per-user licence fees on a packaged platform have grown larger than the cost of owning your own system.
A bespoke build for an agency is usually a custom CRM and workflow layer that models your exact process and integrates with the portals and finance systems you already use - delivered with no per-user fees and full data ownership. Softomate builds these as custom property and agency software, and as bespoke CRM where the CRM is the core. Both typically start from £15,000 for a focused first build.
| Factor | Off-the-shelf (Reapit/Alto/Street) | Bespoke build |
|---|---|---|
| Core agency workflow | Strong, standardised | Built to your exact process |
| Prospecting edge | Generic, shared with every other user | Your method, automated and protected |
| Multi-brand / hybrid ops | Often awkward | Modelled natively |
| Integration (portals, accounts, AML) | Pre-built but fixed | Exactly what you need |
| Compliance (AML, material information) | Built in to the product | Built into your process |
| Cost model | £70 to £2,000+ per month, per branch/user | From £15,000 build, you own it |
| Best for | Standard process, most agencies | Process-as-advantage, scale, hybrid ops |
The honest rule, the same one that applies to any software decision: buy the platform that closes your specific funnel leak, then make compliance and progression automatic - do not build because bespoke sounds better, and do not buy if the product forces you to abandon the thing you win on.
Off-the-shelf PropTech runs on per-branch or per-user monthly fees, from roughly £70 per month for entry tools to over £2,000 per month for larger full-feature deployments. A bespoke build typically starts from £15,000 for a focused first system covering your core workflow, rising with integrations and the number of brands or branches. The crossover point is reached when the monthly licence cost across all your users and branches, plus the cost of the workarounds you run to fit the product, exceeds the cost of owning a system built for you. For a single small branch, buy. For a growing multi-branch or hybrid operation with a process that is a genuine edge, the build often pays back inside the first year.

There is no single best - it depends on your size and where you compete. Reapit and Alto suit agencies wanting end-to-end scale; Street suits those wanting modern AI-led automation; Dezrez adds built-in conveyancing and accounting; entry tools from around £70 per month suit small independents. The best system is the one that closes your specific funnel leak. If your edge is a process no product models, a bespoke build is the better answer.
Off-the-shelf platforms run from roughly £70 per month for entry tools to over £2,000 per month for larger full-feature deployments, charged per branch or per user. A bespoke build typically starts from £15,000 for a focused first system you own outright, with no per-user fees. The right comparison is total cost across all users and branches plus the cost of any workarounds, not the headline monthly price.
Most letting agents should buy - tenancy management, referencing, deposit handling, and client accounting are well covered by packaged products. Build when you run a hybrid sales-and-lettings or multi-brand operation that no single product handles cleanly, when you have a proprietary process worth automating, or when per-user fees across your branches have grown larger than the cost of owning a bespoke system.
Yes. A bespoke agency system is built to feed Rightmove, Zoopla, and OnTheMarket through their data feeds, the same way packaged products do, while modelling the parts of your workflow the products cannot. Integration with your accounting, AML and referencing tools is built to your exact needs rather than limited to the fixed connectors a packaged product ships with.
Compliance is built into the process during the build. HMRC anti-money-laundering supervision and Trading Standards material-information rules apply to every listing, and a bespoke system is designed to capture the required checks and information at the right stage rather than leaving them as a manual add-on. This is one of the advantages of a build: compliance is part of the workflow, not a separate task.
PropTech is not a single buy-or-build decision; it is about which part of the journey - prospecting, progression, lettings, compliance - is where your agency competes. Off-the-shelf platforms like Reapit, Alto, Street, and Dezrez cover the standard workflow well, from around £70 to over £2,000 per month, and suit most agencies. A bespoke build from £15,000 wins when your process is a genuine competitive advantage a product cannot model, when you run a hybrid or multi-brand operation, or when licence fees have outgrown the cost of ownership. Buy the system that closes your funnel leak; build when your process is the product.
