Foundations
A cash and payments workspace for mid-sized companies: every account in one position, approvals by policy, and currency locked before money moves.
1.1Purpose
The H of a ledger, crossbar set high as in a classical capital, beside a serif that reads like a signature. Treasury software that looks like it belongs in a boardroom.
1.2Audience
Who it is for
Group treasurers and finance controllers moving money across entities and banks.
Positioning
For finance teams with more than one bank. Unlike bank portals, Halden shows one cash position and a single approval trail.
1.3Principles
- P1
One cash position
Balances from every bank and currency roll up into a single figure, with the split by currency beside it.
- P2
Approvals by rule
Payments over a threshold need two approvers. The rule is visible on the payment, so nobody has to ask why it is waiting.
- P3
FX at the moment of approval
The rate is locked while the approver signs, and the batch records which rate was used.
Voice
How Halden sounds in product, support and marketing. One voice; the tone moves with the moment, not the channel.
2.1Traits
Composed
The tone of a good private bank: measured, never casual, never cold.
Precise
Amounts in full with currency. Rounded figures only in charts, and labelled as such.
Auditable
Every action is described the way it will appear in the audit log.
2.2Say this, not that

Logo
One mark, one wordmark, one horizontal lockup. The mark is drawn on a 48-unit grid and is never redrawn, only scaled.
3.1Lockups
3.2Construction
Construction circles and the 4-unit grid the mark is drawn on.
- Grid

- Lockup
- Mark 128.43 : word 322 units wide

3.3Clear space and size
Shown at true size. Below these the mark fills in and the word loses its counters.
3.4Misuse
Do not stretch or squash
Do not rotate
Do not recolour
Do not outline
Do not add effects
Do not set on low contrast

5.3Setting
Sentence case
Headings, buttons and labels. Title case only for product names.
Tabular figures
Every amount, time and count, so columns line up and values do not jump.
60–75 characters
Running text measure. Short labels may run to the edge of their container.
Layout
Two grids and one spacing scale cover every screen. Print uses the same 12 columns on the A-series.
6.1Grid
6.2Spacing
A 4 px base. Components step on 4 and 8; sections on 48 and up.

- Body text is Night on Ivory: 16.9:1, AAA.
- Bordeaux can carry text on Ivory (11.2:1).
- Headings use Instrument Serif; amounts use tabular figures.
- Copy follows the house style in 2.3, starting with “Full amounts with two decimals”.
