What is a secured advance in construction?
A secured advance is money a client pays a contractor against materials brought to site but not yet built into the work, secured on those materials and recovered from later running account bills as the materials are used, or within the number of bills the contract sets.
Also called secured advance against materials, advance on materials brought to site.

Secured advance in plain words
The contractor has paid for cement, steel or pipe that is sitting on site, and no bill can claim it yet because no work using it has been measured. A secured advance pays part of that value early. When the materials are built in and billed, the advance is deducted from the bill. The share paid and the materials allowed are set by the contract: one BHEL EPC tender corrigendum of 28 July 2026, for example, allows up to 75% of invoice value, or 75% of the value at BOQ rates if that is less, for materials that are not combustible, fragile or perishable, and recovers the advance within three to four later RA bills whether or not the materials have been used.
What is the difference between a secured advance and a mobilisation advance?
A mobilisation advance funds the start of the job and is backed by a bank guarantee; a secured advance funds materials already on site and is secured on those materials. Both are recovered from later RA bills.
| Secured advance | Mobilisation advance | |
|---|---|---|
| What it pays for | Materials brought to site and not yet used in the work | Site set-up and early costs before billing starts |
| Security | The materials themselves | A bank guarantee; CPWD General Conditions of Contract 2019 ask for 110% of the outstanding advance |
| When it is paid | During execution, as materials arrive | At the start of the contract |
| How it is recovered | From the bills in which the materials are used, or within a set number of bills, as the contract sets | A share of each RA bill until repaid |
Sources: a CAG audit report (2025, chapter V) that sets the two advances side by side, a BHEL tender corrigendum of 28 July 2026 for the 75% of invoice value example, and CPWD General Conditions of Contract 2019 as cited in Crestline's mobilisation advance entry. A contract's own clauses override all three.
Why does secured advance matter?
A secured advance turns materials the contractor has already paid for into cash before they can be billed, so less of the project is funded from the contractor's own working capital. The recovery comes off later bills, so cash received drops when the materials are used.
Where does secured advance mislead?
A secured advance is only available where the contract provides for it, and the share, the eligible materials and the recovery rule differ between contracts; a CAG audit has flagged secured advances paid where the contract made no provision for them.

What do people get wrong about secured advance?
- Treating the advance as revenue
- A secured advance is repaid out of later bills. Booked as earnings, it makes a project look better funded than it is until the recovery arrives.
- Losing track of which materials it covers
- Recovery follows the materials. Without a record of which lot each advance was paid on, the deduction on a later bill cannot be checked.
