From site to figures
The worker enters hours on site and photographs the receipt. Once they are approved, ZERLOS puts them into the right estimate section and recalculates the project profit.
The worker enters hours on site (Foundations · 8.5 h) and photographs the receipt: AI reads the supplier, date, amount and VAT.
The manager approves the entries. Only then do they land in the estimate section “Foundations”.
The worker enters hours on site (Frame · 9.0 h) and photographs the receipt: AI reads the supplier, date, amount and VAT.
The manager approves the entries. Only then do they land in the estimate section “Frame”.
The worker enters hours on site (Roof · 7.5 h) and photographs the receipt: AI reads the supplier, date, amount and VAT.
The manager approves the entries. Only then do they land in the estimate section “Roof”.
The worker enters hours on site (Finishing · 8.0 h) and photographs the receipt: AI reads the supplier, date, amount and VAT.
The manager approves the entries. Only then do they land in the estimate section “Finishing”.
Site finished: profit and margin are visible at every stage, not at year end.

Analytics
Company turnover, profit, forecast and project control on one page, by week, month and year.

Projects and estimates
You import your own estimate in one click, and it splits into sections and items at once.
- Excel at no charge; AI reads a PDF, and the result is a draft you check
- Estimate summary with a chart
- “Compare with past estimates”: a price database from your earlier estimates
03 / 10
Hours
The worker enters hours on the phone and picks the site and the estimate item.
- The entry goes for approval; after two levels the hours are in the site’s cost
- Overtime is counted against the monthly norm, not per day
- The manager sees every entry awaiting approval
04 / 10
Absences
The employee requests holiday or sick days, the manager approves.
- The calendar shows who is away and when
- Absences go into the company hourly rate, not into project costs
05 / 10
Expenses
Photograph the receipt on the phone, and AI reads the supplier, date, amount and VAT.
- AI also suggests the document type and cost type; we switch AI reading on together with you
- A person picks the site and the estimate item, the manager approves
- Once approved, the expense is in the site’s costs
06 / 10
Outgoing invoices
Invoice register by site: amount, due date, overdue ones in red with the number of days.
- Enter the payment date and the overdue invoice turns green
07 / 10
Warehouse
Materials are entered by base: the company store and the site stores.
- Moved between bases and issued on site; you see how much money is tied up in each base
- Tools and equipment are registered to a named person
- Move history and monitored equipment costs
08 / 10
Reports
Every report from approved data, as PDF or Excel:
09 / 10
Staff
One card per employee: personal data, permissions, projects, employment, pay, absences and the danger zone.
- Pay, contracts and employment: contract number and type, time with the company
- Permissions per person: a worker never sees euros
- Absences this year and the projects the person works on
10 / 10
Company structure
Who reports to whom, who approves what and who runs which project.
- You build the structure by dragging people under a manager
- Delegate permissions, approval (levels 1 and 2) and project management
- Everyone sees only their own branch
