Reports
Reports gives you accounting-oriented views on top of the same sales, stock and purchase data as Analytics, formatted for bookkeeping rather than trend-spotting. Find it under Reports.
COGS by period
Cost of goods sold broken down by week/month/quarter/year (choose the period and year), each row showing:
- Units sold
- Revenue, COGS, selling fees (channel commission), profit, and margin %
By product
The same revenue/COGS/fees/profit/margin breakdown as COGS by period, but grouped by product instead of by time period, for a chosen year.
Profit
The bottom line, period by period: what came in, what it cost to make, and what the workshop spent to keep the lights on.

Each row runs:
Revenue − COGS = Gross profit, then − selling fees (channel commission) − operating expenses (rent, utilities, subscriptions) − prototyping (materials spent on samples, which never reach a sale) − depreciation (tools and equipment) = net profit, with the margin as a percentage of revenue.
Underneath, operating expenses are broken down by category, so "where did 1 400 € of expenses go" has an answer without opening another screen.
Two things are deliberately excluded, because they are already counted elsewhere:
- Expenses that were spread over goods on a receipt (delivery, customs) — they are inside COGS already.
- Materials still sitting in stock — the report follows sales, not purchases.
Inventory valuation
A snapshot of what your current stock is worth:
- Materials — quantity and value on hand, per material
- Finished goods & items — quantity and value on hand, per product/component, labeled as Product or Component
- Totals: materials value, finished goods value, and total inventory value
Materials are valued at what is available — stock that has already been reserved into finished goods is counted inside those goods, not twice.
You can value stock as of a past date, and the report is honest about what that means: materials are replayed from the movement log, so a purchase entered late counts from the day it was entered; finished goods are left out of a past-date valuation entirely, because there is no movement history for them yet and any figure would be a guess.
Purchase ledger
Everything bought in a period, from the paperwork side: receipts by period and one row per document, split into inventory, fixed assets, expenses and VAT, with what is still unpaid.
It also lists purchases with no document attached — real purchases that never got a receipt, which the ledger above cannot cover. They are shown rather than hidden, so the gap is visible.
Fixed assets
The register of what the workshop owns: every item with its purchase date and cost, accumulated depreciation, what was charged in the chosen period, current book value and status. Written-off items stay listed with their reason.
Payables
What is still owed to suppliers, aged from the document date into 0-30, 31-60, 61-90 and 90+ day buckets, by supplier and by document.
There are no payment terms in Masto Control, so nothing here is called overdue — the ageing is from the document date, and what counts as late is your judgement.
Excel export
Every tab has its own Export Excel button, producing a spreadsheet of exactly what's on screen (same period/year filter) — handy for handing a specific report to a bookkeeper without them needing app access.
Reports and Sales analytics cover overlapping ground but serve different purposes: Analytics is for spotting trends (forecasting, by-channel comparison), Reports is for accounting close (COGS, margins, profit, valuation) with per-tab export.
