Contracting software that costs the project, not the month

A contractor’s profit and loss for April tells you almost nothing. What matters is whether the Bandra site is making money, and that question needs material, labour, subcontractors and retention all tagged to the site from the day work starts.

What contractors use it for

Everything tagged to a site

Material, labour, subcontractor bills and plant hire carry the project, so a site-wise profit is a filter rather than a reconstruction.

Running account bills

Cumulative measurement, previous certified, this bill — the shape a client actually certifies against, rather than a plain sales invoice.

Retention held and released

Retention deducted on certification and tracked as an asset until it falls due, because it is money you are owed and it is easy to forget.

Material at site

Cement, steel and fittings issued to a site are stock at that location until consumed, not written off the moment the lorry leaves the yard.

Subcontractor accounts

Work orders, running bills, advances and retention per subcontractor, with TDS deducted where it applies.

Labour attendance at the site

Geofenced check-in at the site, feeding the wage calculation and the project’s labour cost from the same record.

How a contractor sets it up

  1. Create a cost centre per site. That one decision is what makes every report below possible.
  2. Budget by head. Material, labour, subcontractor and plant, so overspend is visible while there is still time to act.
  3. Tag every document. Purchase, issue, subcontractor bill and wage — each carries its site, mostly by inheritance rather than by typing.
  4. Bill on running account. With retention deducted and tracked until release.

Construction questions

Can I see profit per site?

Yes. A site is a cost centre, and material, labour, subcontractor bills and plant hire all carry it, so site-wise cost and profit are a filter on the same postings rather than a separate exercise at month end.

Does tBiz handle retention money?

Yes. Retention is deducted when a running account bill is certified and held as a receivable until it becomes due, so it stays visible instead of being remembered a year late.

How is material issued to a site treated?

As stock at that location until it is consumed, which is the only way to know what is actually lying at site versus what has been built into the work.

Can I track subcontractors separately?

Yes — work orders, running bills, advances, retention and TDS per subcontractor, with their cost landing against the right site.
