Run the whole business on one ledger that balances.
Core is Sinad's operational heart: quote to invoice to stock movement to journal — every step writes its own accounting, and the trial balance always closes at 0.00.
Open what you need today — every module reads and writes the same books, so there are no islands and no double entry.
How it works
From quote to journal — no hands carrying numbers.
One connected path: you do the selling, Core writes the accounting.

Accounting
Books with an old accountant's rigor — at modern speed.
Double entry under every movement, statements built in real time from the same numbers, and periods that close with a full audit trail.
Automatic double entry
Every sale, purchase, payment and stock movement generates its balanced journal — no separate accounting step.
Real-time statements
Income statement, balance sheet, cash flow and trial balance — same numbers, any moment.
Solid period close
Close the month with confidence: no entries land in a closed period, and opening balances lock once approved.
Full audit trail
Who created, who edited, who posted — every entry carries its whole story.

Stock you can trust before you promise a customer.
Core separates what exists from what you can sell: it counts reservations against open orders and stops below-zero selling before it happens.

Every stock adjustment carries a recorded reason: count, damage, loss.
Landed cost allocated by value, weight or volume across a shipment's items.

Quick questions
Before you start
I'm moving from Excel or another system — how do I start?
Start with a ready chart of accounts or import yours as CSV, then enter opening balances in a dedicated screen that verifies they balance and locks them once approved — your history starts clean from day one.
Can I invite my accountant?
Yes — invite them with their own account and set their permissions: read-only over books and reports, or full journal and posting rights. Everything they do shows in the audit trail.
How do I know who did what?
Every document and entry carries its record: who created, who edited, who posted and when. The system-wide change log documents the rest.
How do reports handle multiple currencies?
Each document keeps its currency and exchange rate, and reports aggregate in base currency — so dollars never mix with euros in one number. Periodic revaluation keeps foreign balances honest.
