At the top of the editor, configure the template properties:
| Field | Required | Notes |
|---|---|---|
| Template name | ✅ | Displayed in the reports list |
| Country | — | Enables country-specific tax tag autocomplete in formulas |
| Period | ✅ | Controls how date filters work when the report is run |
| Exclude year-end transactions | — | Checkbox — excludes year-closing journal entries from results |
Period options:
| Option | Description |
|---|---|
| Range | User picks a start and end date when running the report |
| Monthly | Report is scoped to a single calendar month |
| Quarterly | Report is scoped to a single quarter |
| Yearly | Report is scoped to a full year |
Rows define what appears in the report. Each row has a label and formula cells for each column.
Adding rows:
Row hierarchy: Rows can be nested to create parent/child groupings. Child rows are indented visually by their depth level. Deleting a parent row removes all its children.
New templates start with a single column (A). You can add up to 5 columns (A–E).
Each row/column cell uses a single-line formula editor with autocomplete. Light supports the following functions:
| Function | Syntax | Description |
|---|---|---|
SUM | SUM(A1, B3, -A4) | Sums the values of referenced cells in this template |
ACP | ACP(4, 5, -6) | Itemises and sums accounts whose code starts with the given prefix |
ACPSUM | ACPSUM(2, -3, 4) | Same as ACP but summarised into a single value |
ACT | ACT(REVENUE, -COST_OF_SALES) | Itemises and sums accounts by account type |
ACTSUM | ACTSUM(REVENUE, -COST_OF_SALES) | Same as ACT but summarised |
ACTCUR | ACTCUR(BANK, CARD, CASH_AND_EQUIVALENTS) | Sums accounts by type in their account currency (for bank/cash accounts) |
TAXTAG | TAXTAG(UK_0, -UK_4) | Sums amounts by tax tag (only available when a country is set on the template) |
Tips:
- to subtract it (e.g. ACP(4, -5) adds account-code-4 and subtracts account-code-5)SUM to reference other cells in the template — for example SUM(A1, A2, A3) to total three rowsACT(), cell references inside SUM(), tax tags inside TAXTAG())Click Save in the top bar to save the template. The report is immediately available in the reports list under Planning & Reports → Reports. Saved templates regenerate with current data every time you open them — no need to reconfigure.
To rename a saved report, edit the template name field and click Save again.
Open any saved Table report from the reports list. Use the filters at the top to control the output:
Click any cell value to drill into the underlying ledger transactions.
To create a variation of an existing template:
The copy opens with a timestamp appended to the name. Edit and save as needed.
