The Problem

Running a business is complicated.
ERP software shouldn't be.

Designed for

The accountant and the executive

Both served, neither in the other's way.

The Accountant

  • Journal entries, cost centres, VAT, reconciliation, audit trails
  • Precision, process compliance, full control over the ledger
  • Invoices, contracts, and documents connected to their accounting entries — not stored in separate systems

"Accounting records and documents live side by side"

The Executive

  • Cash position, budget vs. actual, outstanding payables, revenue trends
  • Clarity and speed — no accounting mechanics required
  • Budget and forecast constantly aligned with actuals

"You manage the future, not the past"

The same underlying data powers both views. Each user gets the right lens on the business — and one does not get in the way of the other.

Leiðir — Old Norse for "the path." Guided by the vegvisir, the Norse wayfinding compass. The name reflects the product's purpose: giving businesses clear direction through complex data. Project started March 2026.

AI Integration

Core processes.
Current with the times.

A modern ERP should evolve with the tools available. Leiðir has an integrated LLM engine — not an add-on, not a roadmap item.

Adopt new technology where it genuinely improves a core process. Ignore it where it does not.
