The books, kept where the work already happens
Irish invoicing, VAT, payroll and statutory accounts in one system. Double entry at the core means the books cannot go out of balance; the VAT3, the payslips and the year-end accounts fall out of figures that are already right.





Watch it work a period
Ask the books a question, raise an invoice, reconcile the bank, run payroll, build the VAT3. Or take the mouse and drive it yourself.
A demo company, on sample figures · the screens above are the real product
A recording of LogOS in use: asking what VAT is owed for the period, raising an invoice and watching the balanced journal post, clearing an unmatched bank line, running payroll gross to net, then building the VAT3 and reconciling it to the ledger.
The Irish year, handled
The ledger
Double entry enforced in the ledger itself. A posting that does not balance is rejected, so the trial balance agrees every time you open it.
Sales and purchases
Invoicing with the full VAT breakdown, aged debtors, supplier bills approved before they post, SEPA payment runs.
Bank
Every current, savings, card and cash account on its own ledger, statements tied out to the closing balance.
Payroll
PAYE, PRSI and USC worked out cumulatively, payslips reconciling gross to net, the payroll journal posted with the run.
VAT and returns
The VAT3 built straight from the ledger every period, the RTD once a year, reconciled against what was filed.
Year end
The corporation tax computation, capital allowances and the statutory accounts, produced from the same books.
Running on LogOS starts with being a client
LogOS is not sold on its own. It is the accounting engine inside the systems we build, so the businesses running on it are our software clients first. Book a call and we will scope the system we would build around your operation.
