Everything your business needsAccounting, Irish tax, payroll, and company filings, all in one place
ComplianceOS runs your books, prepares your Irish tax and CRO filings, and handles payroll. About 25 helpers work quietly in the background to keep you ahead of every deadline. You stay in control, and nothing is filed without your approval.
Important: ComplianceOS prepares your figures and paperwork automatically, but it is not legal or tax advice. You or your accountant check and approve every filing before it goes anywhere.
The background work
About 25 helpers, working in the background
You should not have to remember every deadline or chase every invoice yourself. ComplianceOS watches your accounts, your tax dates, and your payroll every day, prepares the work, and gives you one simple list to approve.
It watches
Every day, in the background, across your accounts, deadlines, and bank feed.
It prepares
Drafts, matches, and reminders are made ready in advance, not at the last minute.
You approve
Everything lands on one list. One click confirms it. Nothing is filed or sent without you.
VAT3 ready before the 23rd
Your VAT3 is drafted and checked from your real transactions days before the deadline. You just review it and approve.
Overdue invoices chased for you
A polite reminder goes out to a late-paying customer, but only once you say yes.
Duplicate payments flagged
If a bill looks like it is about to be paid twice, you get a warning before it happens, not after.
Cash shortfalls seen early
A dip in cash before a big tax bill lands gets flagged with enough notice to plan around it.
A tax-saving watchdog
It keeps watch for reliefs and credits you may be entitled to and flags them for your accountant to confirm.
Receipts and letters, read for you
Photograph a receipt or a Revenue letter and the details are pulled out and filed automatically.
A compliance assistant you can ask
Ask a plain-English question and get an answer with the actual Revenue or CRO guidance it is based on.
One list, one approval
Every deadline is prepared ahead of time, and it all lands on one simple list. You approve, and it goes.
Every suggestion is clearly labelled as AI and always waits for your approval before anything happens. That is human oversight by design, not an afterthought. Every plan includes a generous monthly allowance of AI credits, with more available on demand.
