Proplio vs PayProp for Letting Agent Compliance: An Honest 2026 Comparison

The short version

PayProp and Proplio overlap less than any pairing we have written about. PayProp is an automated rental payment and client accounting platform — rent collection, bank-integrated reconciliation, same-day payments to landlords and contractors, arrears chasing. Proplio is a compliance platform that does none of that.

The complication is the word "compliance", because both companies use it and mean different things. PayProp's compliance story is client-money compliance: a tamper-proof audit log, CMP-recognised client accounts with FSCS protection, remote client-money checks. Proplio's compliance story is property compliance: gas safety, EICR, EPC, licensing — the certificates with statutory deadlines and five-figure penalties attached. PayProp is genuinely strong at the first. Certificate tracking is not part of its marketed feature set at all.

So this is less "which one wins" and more "these are two different risks, and most managed-lettings agencies carry both". This is the honest 1:1 comparison. We make Proplio, so we are biased — we have tried to be fair about where PayProp wins, and it wins its own lane comfortably.

What each product is actually for

PayProp was built around the movement of rent money. Running since 2004, its UK site reports £2.6bn processed annually and 1,300+ UK letting agencies on the platform. Rent comes in, the platform reconciles it against a live bank feed in real time, and same-day payment runs push money out to landlords, contractors, and the agency's own commission. Arrears get chased automatically by email and text, tenants get a branded portal, landlords get statements, and every action on the platform lands in an undeletable audit log. Since its 2023 merger with Reapit (backed by Accel-KKR), it sits inside a wider property-software group, though it still trades under the PayProp name. For the money side of running a lettings book, it is a category leader — PayProp itself claims client agencies grow around 20% on average in their first year.

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 rent collection, no reconciliation, no payment runs, no arrears management, no tenant portal.

The usual advice in these comparisons — choose based on which spine fits your operational reality — half-applies here. If rent processing is the pain, PayProp; if certificate oversight is the pain, Proplio. But because the products barely overlap, the honest answer for most managed-lettings agencies is that this is not an either/or at all.

"Compliance" means two different things here

Worth slowing down on, because the word is doing double duty.

Client-money compliance is about the rent flowing through your client account: can you prove where every pound went, are client funds protected, can your CMP scheme and your auditor verify it. PayProp is built for this. Client funds sit in CMP-recognised bank accounts with FSCS protection, every transaction lives in a tamper-proof audit trail, and a Propertymark partnership can give Propertymark's compliance team read-only access to the client account so client-money checks can happen remotely. If you have ever burned days assembling evidence for a CMP audit, that is a real, valuable capability — and nothing in Proplio's lane touches it.

Property compliance is about the buildings: is the gas certificate current, is the EICR inside five years, is the HMO licence renewed, can you evidence all of it when a council officer asks. This is where the statutory penalties live — up to £40,000 for an EICR breach, up to £40,000 per unlicensed HMO, up to £20,000 per Right to Rent failure. See the full compliance checklist for the obligations and the landlord fines guide for the penalty regime.

PayProp's public UK pages market the first and, as far as we can find, not the second: no certificate storage, no gas safety / EICR / EPC expiry tracking, no compliance-deadline reminders appear in its advertised feature set. Its reminder machinery is aimed at tenants in arrears, not at agents about expiring certificates. A small unadvertised feature could exist behind the login — but if certificate deadlines are the risk you are managing, you should not be relying on one.

Certificate compliance, head to head

Shorter than usual, because one side of the table is largely empty.

Compliance type coverage. 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 you track. PayProp does not market a certificate register at all; in practice, PayProp agencies tend to track certificates in a spreadsheet alongside it, with everything that implies — see where the spreadsheet breaks.

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). PayProp's dashboards are payment-led — arrears, reconciliation, portfolio income — which is the right shape for its job and no substitute for this one.

Reminder ladder. Proplio fires reminders at 90, 60, 30, 14, and 7 days before expiry, configurable per agency. The 90-day lead time is the one that matters — time to book a Gas Safe engineer or an electrician before there is pressure on the date. PayProp's documented reminders chase tenants in arrears; certificate-renewal reminders are not part of its marketed feature set.

Audit-ready PDF report. Proplio generates a single PDF compliance pack per property in one click — every certificate bundled, full audit trail, unique verification ID — a defensible artefact for a council enforcement officer or an insurance renewal. PayProp's audit strength is the client-money side, covered above; it is excellent there and not built for this.

Landlord-facing visibility. Proplio offers a read-only share link per landlord — their properties' compliance status, no login needed. PayProp's landlord communication is statements and payment updates: money visibility, not compliance visibility.

Contractor management. Proplio's contractor module is for compliance contractors — gas engineers, electricians, EPC assessors — with one-click renewal emails carrying property details pre-filled. PayProp touches contractors from the other end: it pays them, same-day, out of the payment run, and connects to maintenance-reporting platforms such as Fixflo. Paying a contractor and chasing one to renew a certificate are different jobs; the two modules are complementary rather than competing.

Client accounting and rent processing

PayProp wins. Proplio does not compete here, and this section is short only because the verdict is one-sided, not because the capability is small.

If your biggest operational friction is the money — collecting rent, reconciling it against the bank, paying landlords and contractors on time, chasing arrears, surviving the client-money audit — you need a client accounting platform, and PayProp is one of the strongest in the UK market: live bank integration, real-time reconciliation, same-day automated payment runs, FSCS-protected CMP-recognised client accounts, automated arrears chasing, a branded tenant portal, and unlimited users at no extra cost. There is no honest version of this comparison where Proplio is the answer for any of that.

This is why "Proplio vs PayProp" is rarely the right question. The right question is "what tool runs which part of my operation, and what does the combined cost look like".

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.

PayProp: custom quote, scaled to your portfolio. PayProp does not publish a full price list. At the time of writing, its UK pricing page describes three components: a monthly service fee of less than 1% of your processing volume, a setup fee of £600–£2,000 depending on portfolio size, and a licence from £79/month — with no charge for extra users. The exact percentage is not published and the realised figure depends on your rent roll, so we will not invent typical monthly totals here: get a proposal sized to your book.

Two honest caveats. First, you are not buying the same product — PayProp's fee covers an automated client accounting platform that can genuinely reduce headcount-hours on the money side; Proplio's covers compliance only. The straight per-pound comparison is misleading in both directions. Second, PayProp's model means cost rises with the rent you process — reasonable if the payment automation is what you are buying, but a heavyweight commitment if certificate tracking is the actual need. Nobody should onboard a payment platform with a setup fee to solve a certificate-deadline problem.

Adding Proplio alongside PayProp

Note the heading: this is "adding", not "switching", because there is usually nothing to switch from. PayProp does not market a compliance register, so there is no compliance export to migrate — it offers reporting and an API for its own data, but agents moving certificate records into a compliance tool are typically re-keying dates from a spreadsheet or from the certificates themselves rather than importing a PayProp export.

The flow, for most agencies, is an afternoon:

1. 1Gather your certificate dates from wherever they currently live — spreadsheet, inbox, filing cabinet.
2. 2Build a CSV — property address, compliance type, last done date, expiry date, contractor — and map it to Proplio's import template.
3. 3Upload. The full portfolio loads in minutes.
4. 4Upload existing certificate PDFs against each compliance item. Optional but worth doing for the audit pack.
5. 5Reminders start firing automatically. No manual setup of individual deadlines.

PayProp keeps running the money throughout. Nothing about the payment workflow changes, no integration is needed, and the compliance system of record starts existing where previously there was not one.

Side-by-side

Which to choose

Choose Proplio if:

• Certificate compliance oversight is the operational risk that keeps you up at night
• You want a flat monthly cost that does not grow with your portfolio or your rent roll
• You need the audit-ready PDF pack for council inspections, trading standards visits, or insurance renewals
• Your rent processing is already handled — by PayProp or otherwise — and the gap is the compliance system of record

Choose PayProp if:

• Collecting, reconciling, and paying out rent is your biggest daily friction
• Client-money compliance — CMP, FSCS protection, audit-ready transaction records — is a real exposure for your agency
• You want arrears chased automatically and landlords and contractors paid same-day without manual payment runs
• You are clear-eyed that certificate compliance will still need its own answer

Run both if:

• You are a managed-lettings agency of any real size — the two risks (money and certificates) are both live, and neither tool covers the other's lane
• You run PayProp today and certificates live in a spreadsheet — that spreadsheet is the weakest link in your compliance story
• A council inspection or insurance renewal is on the horizon and you need a defensible one-click audit pack without touching your payment stack

For the broader landscape, see the compliance software comparison. For the head-to-head with PayProp's group stablemate and the other operations platforms, see Proplio vs Reapit, Proplio vs Goodlord, and Proplio vs Arthur Online, and against the dominant repairs platform, Proplio vs Fixflo.

Running both

The combined stack looks like this:

• PayProp for the money — rent collection, live reconciliation, same-day payment runs, arrears chasing, statements, tenant portal, client-money audit trail
• Proplio for the compliance system of record — every certificate, every expiry, the 90/60/30/14/7 reminder ladder, audit packs, landlord share links, the portfolio RAG view

The two do not need to integrate. Payment data lives in PayProp, compliance data lives in Proplio, and the agency-side workflows touch each tool for the part it owns. Because the products barely overlap, there is no duplicated spend to rationalise — Proplio's £29/month is additive, and it is buying cover for a risk your payment platform does not carry.

The objection here is "another tab open". That is real. The counter is that the cost of a missed compliance deadline — up to £40,000 for an EICR breach, up to £40,000 per unlicensed HMO, 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

• PayProp is an automated rental payment and client accounting platform; Proplio is a certificate compliance platform. They barely overlap — this is the least either/or comparison in the lettings stack.
• "Compliance" is doing double duty. PayProp's compliance is client-money compliance — tamper-proof audit log, CMP-recognised FSCS-protected client accounts, a remote Propertymark audit programme — and it is genuinely strong there. Certificate tracking, renewal reminders, and audit packs are not part of its marketed feature set.
• For rent processing, reconciliation, payment runs, and arrears, PayProp wins outright. For certificate depth — twelve UK types, the 90/60/30/14/7 reminder ladder, one-click audit PDF, RAG dashboard, landlord share links — Proplio wins by default, because PayProp does not play.
• Pricing models are structurally different. Proplio is £29/month flat; PayProp is quote-based and scales with your rent roll, with a setup fee on top — get a proposal sized to your book before comparing pounds.
• If you run PayProp and your certificates live in a spreadsheet, the spreadsheet is the gap. Proplio closes it in an afternoon without touching the payment stack.
