Proplio vs SME Professional for Letting Agent Compliance: An Honest 2026 Comparison

The short version

SME Professional and Proplio overlap on exactly one module and differ on everything else. SME Professional is a cloud-based all-in-one CRM for UK estate and letting agencies — client accounting, property marketing, tenancy packs with e-signing, landlord and tenant portals, communications — with a compliance-management module inside it. Proplio is a compliance platform that does none of those other things.

Two things make this comparison different from the usual platform-vs-tracker matchup. First, SME's compliance module is stronger than most: its own material describes managing more than 20 safety certificate types with process controls, contractor workflow, and an audit system — this is not a bolted-on date box, and we are not going to pretend it is. Second, SME does not publish pricing: we could find no pricing page on its site, and the route to a number is booking a demo. Proplio is £29/month flat, self-serve, visible before you sign up.

So the honest framing is this: if you want one system to run the entire agency and you are happy to buy through a demo process, SME Professional is a credible, well-reviewed choice used by more than 1,000 property businesses. If you want compliance depth without adopting (and paying for) a full agency CRM, or you want a defensible audit artefact and landlord visibility with zero rollout effort, Proplio is the sharper tool. We make Proplio, so we are biased — we have tried to be fair about where SME wins, and it wins more than most.

What each product is actually for

SME Professional (made by Lyles Sutherland, based in Edinburgh) was built as the single system an agency runs on. Client accounting with bank feed import, BACS payment files, and landlord and contractor payment schedules — with an Open Banking integration rolling out from January 2026. Lettings management with tenancy packs and e-signatures. Marketing feeds to Rightmove, Zoopla, and OnTheMarket. Landlord and tenant portals, email and SMS templates, customisable dashboards, and an ecosystem of roughly 100 third-party integrations. Compliance management is one module of that whole, sold in two packages — STANDARD and PLUS.

Proplio was built around the compliance lifecycle and nothing else. A property has a list of compliance items. Each item has an expiry date. As that date approaches, reminders fire at 90, 60, 30, 14, and 7 days. When an inspector or landlord asks for evidence, you generate a one-click PDF compliance pack. The portfolio dashboard tells you which properties are red, amber, or green. There is no accounting, no marketing feeds, no tenancy packs, no portals to configure.

Choose based on how much system you want to adopt. SME Professional is a re-platforming decision — demo, quote, onboarding, training, migration. Proplio is a sign-up-and-import decision — properties in via CSV, expiry dates entered, reminders firing, done by the end of the afternoon.

Compliance, head to head

This is the interesting part, because SME Professional competes here more seriously than most platforms we have compared against. See the full compliance checklist for the obligations any tracker has to cover.

Compliance type coverage. SME Professional's compliance page describes managing more than 20 safety certificate types — Landlord Gas Safety, EICR, EPC, PAT, and Legionella Risk Assessment are named explicitly — plus HMO certificate management and safety-equipment lifespan tracking. That is genuine breadth. Proplio ships with twelve UK compliance types as defaults — Gas Safety, EICR, EPC, Legionella, Smoke and CO, Right to Rent, HMO Licence, Selective Licence, PAT Testing, Fire Safety, PRS Database, and PRS Ombudsman — plus custom types per agency for anything else. The practical difference is at the regulatory edge: Proplio treats the Renters' Rights Act obligations — PRS Database registration and PRS Ombudsman membership — as first-class tracked types out of the box. For property-licensing compliance, SME integrates with Yuno, so licensing intelligence comes via a third party rather than natively; Proplio tracks HMO and selective licence expiry natively as compliance items (though it does not do per-council scheme lookups either — no tool should claim that lightly).

Process depth. SME's own framing is "not just a simple date box" — the module carries process controls to ensure safety checks are instructed and completed and expiry dates are not breached, from adding certificates and arranging checks with contractors through managing renewals and notifying landlords. That is a real end-to-end workflow and we will not diminish it. Proplio's equivalent is deliberately leaner: expiry tracking, a configurable reminder ladder, one-click contractor renewal emails with property details pre-filled, and an audit trail — without the surrounding CRM.

Portfolio-wide dashboard. Proplio's home screen is the entire portfolio in one view, every property colour-coded by RAG status: red (overdue), amber (expiring within 60 days), green (compliant), grey (not applicable). SME Professional offers customisable dashboards across the whole product, and its audit system breaks information down by certificate type. Whether the most-watched screen of your working day is compliance-led or operations-led is the thing to check on the demo — in a full agency CRM, compliance is one view among many by necessity.

Reminder ladder. Proplio's reminder ladder is 90, 60, 30, 14, and 7 days before expiry, configurable per agency in settings. The 90-day lead time is the one that matters — it books the Gas Safe engineer before there is any pressure on the date. SME Professional manages renewals and says expiry dates are "not breached", but the reminder schedule and its configurability are not publicly documented — compare the mechanics on a demo.

Audit-ready PDF report. Proplio generates a single PDF compliance pack per property in one click — every certificate bundled, full audit trail of who did what and when, unique verification ID. That is a defensible artefact you can hand straight to a council enforcement officer or trading standards inspector. SME Professional has an in-depth internal audit system, but a one-click shareable audit pack as a handover artefact is not something it publicly documents. If that artefact matters to your council relationship, ask to see SME's equivalent before assuming it exists.

Landlord-facing visibility. SME Professional wins on richness here: certificates are uploaded to each landlord's individual portal, alongside statements and the rest of the landlord relationship — and the branded owner portal option is a genuinely professional touch. Proplio's version is narrower and faster: a read-only share link per landlord showing their properties' compliance status, no login, no portal rollout, live from the moment you send it.

Contractor management. SME Professional's contractor handling is broader and deeper — arranging checks sits inside the compliance process, and contractor payments run through the same client accounting. A standalone tracker cannot close that instruct-pay-file loop, and we will not pretend otherwise. Proplio's contractor module is narrower: compliance contractors — gas engineers, electricians, EPC assessors — with one-click renewal emails carrying property details pre-filled.

The full agency suite

SME Professional wins. Proplio does not compete here.

If what your agency needs is client accounting with bank feeds and payment runs, portal feeds to Rightmove and Zoopla, tenancy packs with e-signatures, landlord and tenant portals, SMS and email templates, and lead management in one login, you need an agency CRM — and SME Professional is a well-regarded one, used by more than 1,000 property businesses, with a large integration ecosystem and structured onboarding that includes training and supported data migration (it rates 4.9 on Google by its own site's account, and 5.0 on Kerfuffle from a small number of reviews — eight at the time of writing). There is no honest version of this comparison where Proplio is the answer for running the agency.

This is why "Proplio vs SME Professional" is rarely the right question. The right question is "how much system do I need to adopt to fix my compliance problem, and what does each path cost".

Pricing

Proplio: £29/month flat, unlimited properties, unlimited team, monthly or annual. No per-unit pricing, no feature tiers, no charges for adding users or properties. The price is on the website; you can sign up without speaking to anyone.

SME Professional: quote-only. We could find no pricing page on smeprofessional.co.uk — the site's route in is booking a demo. The public structure is two packages, STANDARD and PLUS, with feature differences between them (the owner portal, for example, comes unbranded or branded depending on package). We are not going to publish numbers we cannot source: at the time of writing we could find no price anywhere on SME's own site, so treat any figure you see elsewhere as unverified and get a quote sized to your agency.

Two honest observations rather than a cost table this time — a table needs numbers, and only one side of this comparison publishes any.

First, a quote is not a verdict. SME's pricing may well be reasonable for what is a much larger product — nothing here implies otherwise — but you cannot know the figure, or how it scales with your portfolio and team, until you ask. The demo-and-quote process is itself part of the price: budget the time for it.

Second, the products are not the same size. SME's quote buys a full agency CRM; Proplio's £29 buys compliance only. The comparison that genuinely matters is evaluation cost: SME is a demo, a quote, onboarding, and training — Kerfuffle notes onboarding training within a week, which is fast for a CRM but is still a project. Proplio is a sign-up and an import. If compliance is the specific fire you need to put out, weigh the cost of adopting a whole system to fix one module.

Switching compliance tracking to Proplio

The flow, once your property data is out of SME Professional:

1. 1Get your portfolio into a spreadsheet — address, postcode, landlord and tenant details.
2. 2Upload it through Proplio's CSV or Excel property import. Columns are matched automatically, and the full portfolio loads in minutes.
3. 3Enter each property's compliance expiry dates. Proplio lists the applicable compliance types against every property out of the box, so this is date entry, not setup — a portfolio's worth of dates is an hour or two of work from SME's certificate screens.
4. 4Upload existing certificate PDFs against each compliance item. Optional but worth doing for the audit pack.
5. 5Reminders start firing automatically as the dates go in. No manual setup of individual deadlines.

The honest caveat sits at the export end. SME Professional's onboarding includes supported data migration for moving data in, and extensive reporting once you are there — but a CSV or spreadsheet export of the compliance register is not publicly documented. Before planning a move, ask the vendor exactly what export looks like. If a clean export is not available, the expiry dates can be rekeyed by hand — tedious, but a one-off, and the certificates themselves can be re-uploaded as you go.

The two systems do not need to integrate. If you are keeping SME for agency operations, it continues untouched; compliance simply moves to its own system of record. The same handover pattern applies when a portfolio moves between agents — see the compliance handover guide for the wider workflow.

Side-by-side

Which to choose

Choose Proplio if:

• Compliance oversight is the specific operational risk you need to fix, and you do not want to re-platform the agency to fix it
• You want a published flat price you can see before you talk to anyone, and a tool you can adopt in an afternoon
• You need the one-click audit-ready PDF pack for council inspections, trading standards visits, or insurance renewals
• You want landlord visibility via a share link today, without rolling out a portal
• You want the Renters' Rights Act obligations — PRS Database, PRS Ombudsman — tracked as first-class types now

Choose SME Professional if:

• You want one system running the whole agency — accounting, marketing, tenancies, portals, communications — and compliance managed inside it
• The instruct-contractor, pay-contractor, file-certificate loop closing in one system is worth more to you than a standalone tool's depth
• You value an established vendor with structured onboarding — training, supported data migration — and a large integration ecosystem
• You are comfortable buying through a demo-and-quote process rather than self-serve

Run both if:

• SME runs your agency well but you want a compliance-first view of the portfolio, the one-click audit artefact, and no-login landlord share links on top
• A council inspection or insurance renewal is on the horizon and you need a defensible audit pack now, without waiting on a CRM workflow
• You want compliance in a system you can export from at will, alongside the CRM that runs everything else

For the broader landscape and how this fits against spreadsheets and full property-management platforms, see the compliance software comparison. For the head-to-head with the other major operations platforms in the lettings space, see Proplio vs Reapit, Proplio vs Arthur Online, and Proplio vs Goodlord, and against the dominant repairs platform, Proplio vs Fixflo. For the breakpoint where any tool starts paying for itself versus a spreadsheet, see the spreadsheet-to-software switch guide.

Running both

The combined stack looks like this:

• SME Professional for the agency operation — client accounting and payment runs, portal feeds, tenancy packs and e-signing, landlord and tenant portals, communications
• Proplio for the compliance system of record — every certificate, every expiry, every audit trail, every landlord share link, the one-click PDF pack for council inspectors

The two do not need to integrate. Operational and financial data lives in SME. Compliance data lives in Proplio. The agency-side workflows touch each tool for the part it owns, and at £29/month flat the addition barely registers against an agency CRM subscription.

The objection here is "another tab open". That is real — and it is more real against SME than against most platforms, because SME's compliance module is genuinely capable. The counter is the same as ever: the cost of a missed compliance deadline — up to £40,000 for an EICR breach, up to £40,000 per unlicensed HMO plus a rent repayment order, up to £20,000 per Right to Rent failure — makes the cognitive cost of a second tab cheap. See the full landlord fines guide for the penalty regime in 2026.

Key takeaways

• SME Professional is a full agency CRM with a genuinely strong compliance module — 20+ certificate types, contractor workflow, landlord-portal publishing. Proplio is a compliance platform that does not do agency operations. They overlap on one module, and SME's version of that module is better than most.
• SME's structural advantage is the closed loop: instruct the contractor, pay them, and file the certificate in one system. Proplio's structural advantage is focus: RAG-first dashboard, a 90/60/30/14/7 reminder ladder, the one-click audit PDF with verification ID, and no-login landlord share links — as a tool you adopt in an afternoon, not a platform you migrate to.
• Pricing is the sharpest practical difference: Proplio is a published £29/month flat; SME Professional is quote-only, in two packages, with no published numbers we could find at the time of writing.
• Before committing compliance data to SME, ask about export — a CSV export of the compliance register is not publicly documented, and data you cannot get out is data you do not fully own.
• The right question is not "Proplio or SME Professional". It is "how much system do I need to adopt to fix my compliance problem, and what does each path cost to evaluate, buy, and leave".

This article reflects our honest read of the Proplio vs SME Professional comparison as of August 2026. Proplio is our product. SME Professional does not publish pricing on its site, and several capability details (reminder mechanics, audit-pack export, data export) are not publicly documented — always verify on a demo and get a quote sized to your agency.
