Type "property management software" into a search engine and most of what comes back is built for landlords managing their own handful of properties. Useful products, wrong market. A letting agent managing other people's property is running a regulated business with client money, statutory deadlines and three sets of customers, and the software requirements are different in kind, not just in scale. This guide sets out what property management software for letting agents actually needs to do, maps the full agency workflow, and puts realistic numbers on the choice between a multi-tool stack and an all-in-one platform.
Agent needs are not landlord needs
A self-managing landlord tracks their own rent into their own bank account. An agent handles other people's money and other people's legal obligations at scale, and that changes everything the software must do.
- Client accounting, not personal accounting. Rent arrives into a client account, fees are deducted, contractor invoices are paid, and the balance is remitted to the landlord with an itemised statement. Client money handling and clean remittances are the core of the job; landlord apps simply do not have the concept.
- Many landlords, many preferences. Fifty landlords means fifty fee agreements, approval thresholds, payment schedules and communication styles, all of which the system must hold and apply automatically.
- Compliance as a professional duty. Since the Renters' Rights Act commenced on 1 May 2026, every tenancy is periodic, rent rises need annual Section 13 notices, repairs to serious hazards carry Awaab's Law timescales, and civil penalties reach £40,000. The agent is expected to get this right across hundreds of tenancies, with an audit trail to prove it.
- Tax the landlord never sees. Non-resident landlord deductions, quarterly HMRC reporting and contractor CIS are agent problems. Software built for owner-occupier landlords has no answer to them.
- A team, with roles. Negotiators, property managers, inspectors and bookkeepers need different permissions and different views. A single shared login is how mistakes happen and how you fail to work out who made them.
The practical test is quick: ask whether the product can produce a landlord remittance statement and track an NRL deduction. If not, it is a landlord tool, however polished, and our landlord remittance guide explains why that single feature carries so much weight.
The agency workflow map
Agency-grade letting agent software should follow the property through its whole life in your care. The workflow runs in six stages, and the software has a specific job at each one.
| Stage | What happens | What the software must do |
|---|---|---|
| 1. Instruction | Landlord signs terms; property onboarded | Landlord AML checks, signed terms of business, property record with certificates from day one |
| 2. Marketing | Listing prepared and published | Photos, floor plans and descriptions pushed to Rightmove and OnTheMarket without re-keying |
| 3. Application | Enquiries, viewings, offers, referencing | Applicant pipeline, viewing diary, digital onboarding with referencing, Right to Rent and guarantors |
| 4. Tenancy setup | Agreement signed, deposit taken, move-in | E-signed agreement, deposit protected inside 30 days with prescribed information, inventory and meter readings |
| 5. Management | Rent, repairs, inspections, arrears | Rent matching, arrears escalation with evidence trail, maintenance workflow, compliance renewals |
| 6. Review and end | Periodic reviews; notice; check-out | Annual Section 13 rent-review anniversaries, notice tracking with calculated end dates, deposit release, re-let trigger |
Stage six looked different two years ago. Fixed-term renewals are gone; every tenancy now rolls periodically until the tenant gives roughly two months' notice or the landlord establishes a Section 8 ground. That is why a modern system tracks rent-review anniversaries and notices rather than end dates, a shift covered in depth in our periodic tenancy workflow guide.
Notice, too, how much of the map happens away from a desk. Viewings, inspections, check-ins and repair visits all generate data in the field, which is why mobile apps are not a cosmetic feature for agents. LettingGuru ships seven role-specific apps, so an inspector photographs a property on site, a contractor updates a job from the van, and a tenant reports a leak with photos at ten o'clock at night, and every one of those events lands in the same property record your office team sees the next morning. The alternative is field notes typed up later, which in practice means field notes lost.
The integration trap of the multi-tool stack
Many agencies arrive at a stack by accident: a CRM first, then a referencing tool, then a maintenance product, then an accounting package, each solving that month's pain. Every tool was a sensible purchase; the collection is the problem.
- Double entry everywhere. The same tenant is typed into the CRM, the referencing tool, the deposit scheme and the accounts. Each re-key risks an error, and errors in lettings have statutory price tags.
- No single answer to simple questions. "Is 14 Station Road compliant and in arrears?" becomes a tour of three logins. Meanwhile the landlord is on hold.
- Sync that half works. Native integrations between point tools are thinner than the logos page suggests. When a tenancy's data disagrees between systems, each vendor's support team blames the other, and reconciling them becomes an unpaid weekly task.
- Stacked billing. Four to six subscriptions, some per user, some per tenancy, rising independently at each renewal. Few agencies ever total the true monthly figure; most are surprised when they do.
- Compliance gaps at the joins. The referencing tool knows the tenancy started; the compliance tracker was never told. Every handoff between systems is a place where a statutory clock starts ticking unseen.
What the stack really costs
Here is a realistic total-cost comparison for an agency managing 50 properties, using typical market figures for a five-tool stack. Individual quotes vary; the pattern does not.
| Cost line | Five-tool stack | All-in-one (LettingGuru) |
|---|---|---|
| Core CRM | £100 to £200 / month | £374 / month all-in (£299 base + 50 × £1.50) |
| Onboarding and referencing | £100 to £250 / month in per-tenancy fees | |
| Maintenance tool | £75 to £150 / month | |
| E-signature and documents | £25 to £50 / month | |
| Client accounting add-on | £50 to £150 / month | |
| Admin time reconciling systems (approx. 10 hours / month) | £150+ / month in staff cost | |
| Realistic monthly total | £500 to £950 | £374 |
The stack's defenders will say each tool is best in class, and often that is true. The question is whether best-in-class referencing is worth double the total cost and a standing integration burden, when the all-in-one covers the same workflow from £299 per month with every feature included and one support team accountable for the whole chain. For most independent agencies the arithmetic answers itself; full tier details are on our pricing page.
Two costs are deliberately left out of the table, and they cut in the stack's favour even less. Portal membership is one: Rightmove and OnTheMarket charge agencies directly whichever software you run, so it belongs in every budget equally. The other is the cost of making a stack's tools genuinely talk to each other, which in practice means either a consultant's day rate or a standing manual process someone on your team quietly owns. If anything, the comparison above flatters the stack.
What to shortlist in 2026
Whatever you evaluate, hold it to five tests, and insist on seeing each one demonstrated live rather than described on a slide.
- Client accounting is native. It produces a landlord remittance and an itemised statement out of the box, without an accounting bolt-on doing the real work.
- The tenancy model is periodic. Periodic tenancies, Section 13 rent-review anniversaries and Section 8 evidence trails are first-class concepts, not fields repurposed from a fixed-term world.
- The apps are real. Tenants, landlords and contractors get mobile apps they will actually use, because every task they self-serve is a call your team does not take.
- The pricing is published. You can calculate your all-in monthly figure from the website before a salesperson calls you back.
- The portals are fed directly. Listings reach Rightmove and OnTheMarket from the system itself, with no re-keying step waiting to cause a mispriced advert.
Products that pass all five are rarer than the market's noise suggests, and a system that fails the first two is a landlord tool or a sales CRM in agency clothing, whatever the label says.
Frequently asked questions
What is the best property management software for letting agents?
For independent and growing agencies, an agency-grade all-in-one platform is usually the strongest fit because client accounting, compliance and portals are native rather than integrations. LettingGuru is built precisely for that profile from £299 per month; large corporate groups should also evaluate the enterprise CRMs, as our UK comparison sets out.
Can letting agents use landlord software like a self-manage app?
Not realistically beyond a first few properties. Landlord tools lack client accounting, remittances, NRL handling, staff roles and per-landlord fee structures, which are the substance of an agent's obligations rather than nice-to-haves.
Is an all-in-one platform always better than best-of-breed tools?
Not always. An agency with an entrenched CRM and a strong bookkeeping operation can run a stack well. The stack costs more in subscriptions and reconciliation time, and compliance gaps tend to open at the joins between tools, which is why most smaller agencies are better served by one system.
How much does property management software cost for a letting agency?
A realistic five-tool stack lands between £500 and £950 per month for around 50 properties once per-tenancy fees and admin time are counted. An all-in-one is typically far less; LettingGuru is £374 per month at that size, everything included. Our 2026 price guide gives the full breakdown.
Does the Renters' Rights Act change what software I need?
Materially, yes. Since 1 May 2026 there are no fixed terms to renew: systems must track periodic tenancies, notices, annual Section 13 rent reviews and Section 8 evidence trails. Software still organised around fixed-term end dates is working from a data model the law has abolished.
