Registered office management software.
ComplyPost runs the whole registered office service: scan the client post in bulk, let AI match every letter to the right company, monitor who is registered at your address, and keep an audit trail that stands up to inspection.
THE CATEGORY
What registered office management software actually does.
A registered office service has two halves. The address is the easy half. The hard half is everything that arrives at it: HMRC letters, Companies House reminders, banking and legal correspondence for hundreds of client companies — every item needing to be identified, delivered, and evidenced.
ComplyPost is software for that second half. It turns the daily post pile into a classified, client-matched, delivered and logged workflow, and keeps your view of the address reconciled with the Companies House register.
To be clear: ComplyPost is not a registered office provider and does not sell addresses — it is the software for firms that provide the service themselves. Thinking of launching one? Read the guide to offering registered office services.
WHAT IT COVERS
Six jobs, one platform.
Everything a firm needs to run a registered office service profitably — each piece works on its own, together they close the loop.
Client mail processing
Bulk-scan the day's post as one PDF. ComplyPost splits it into letters, reads each one, matches it to the right client company, and queues it for review — no per-letter scanning or renaming.
Mailroom automationCompanies House monitoring
See every company registered at your office address, spot new arrivals you never agreed to host, and keep your client list reconciled against the public record.
Free address lookupClient delivery and portal
Send letters by email from your own domain or give clients a secure portal where they can view, search, and download their correspondence history.

HMRC penalty notices, VAT reminders, confirmation statement dates, and strike-off warnings are detected in the text and flagged with priority before they expire.
HMRC letter handlingCompliance and audit trail
UK-based encrypted storage, role-based access, retention controls, GDPR tooling, and a complete log of every upload, edit, send, view, and download — evidence for AML supervision.

Registered office service is only profitable if the post handling is cheap. Put your firm's volumes through the calculator and see what the manual process costs.
Cost calculatorHOW IT WORKS
From the morning post to a clean audit trail.
Post arrives at your address.
Royal Mail delivers the day's letters for the client companies registered at your office. Instead of opening and judging each one, the pile goes through the scanner as a single batch.
ComplyPost reads everything.
Each letter is separated, the sender and recipient company identified, the content classified, the urgency scored, and any deadline extracted — automatically.
Your team reviews in minutes.
Confirm the routine matches in bulk, correct the rare exception with the original page on screen, and nothing reaches a client without sign-off.
Clients get their post, you keep the record.
Letters go out by email or portal, the searchable archive grows, and the audit trail records exactly what happened to every document.

Run the numbersRegistered office management questions
What is registered office management software?
Software that runs the operational side of providing a registered office service: processing and delivering client post, matching correspondence to the right company, monitoring which companies are registered at your address, detecting statutory deadlines, and keeping an audit trail of every document handled.
Who is ComplyPost for?
UK accountancy practices, bookkeeping firms, company secretarial teams, and solicitors that act as the registered office or care-of address for client companies and handle their statutory post.
How is this different from mail forwarding?
Mail forwarding moves envelopes. ComplyPost reads the contents: it knows a letter is an HMRC penalty notice for a specific client with a 30-day deadline, files it against that client, flags the urgency, delivers a clean PDF with a summary, and logs the whole chain.
Can I see which companies are registered at my office address?
Yes. The free Companies House address lookup shows every company — active and dissolved — registered at any UK address, and the paid platform keeps that list reconciled against your clients on an ongoing basis.
Does it help with AML and professional-body inspections?
The audit trail records every upload, review, send, view, and download, with role-based access and UK-based encrypted storage. When an inspector asks how client mail is handled, you show the log rather than describe a process.
Is ComplyPost a registered office provider?
No. ComplyPost does not sell addresses. It is the software accountancy firms use to run their own registered office service — processing the client post, monitoring the address, and keeping the audit trail. Your firm stays the provider; ComplyPost does the heavy lifting.
Do I need a special scanner to digitise the client post?
No. Any scanner that produces a PDF works — including the scan-to-email button on your office copier. Feed the whole pile through as one multi-page PDF; ComplyPost splits it into individual letters itself. Nothing to buy, nothing to install.
What happens to letters that can't be matched to a client?
They wait in the review queue. Nothing is ever sent automatically without a match your team has confirmed — you assign the odd unknown letter manually, and the system learns from that confirmation so the same sender matches automatically next time.
Does it work with our existing software?
Letters are delivered by ordinary email from your own domain, so it works alongside any practice management system. QuickBooks connects directly for reconciling registered office billing, and a REST API with webhooks is available for custom integrations.
How much does it cost?
The Free plan includes 100 pages a month with no credit card. Starter is £31.99/month with 500 pages, and Pro is £74.99/month with 1,000 pages, unlimited clients, and AI search. Annual billing gets two months free.
