## Gross Amount Due From / Due To Customer
### What Is It?
At the balance sheet date, the contractor must compute whether they are owed money by the customer (asset) or owe excess billing back to the customer (liability).
### Calculation Format
```
Costs incurred to date xxx
Add: Recognised profits (till date) xxx
Less: Recognised losses (till date) (xxx)
-----
xxx
Less: Progress billings (xxx)
[= Amounts billed by contractor,
whether received or not]
-----
Net Amount xxx
```
If Net > 0 (Positive): → Asset = Gross Amount Due FROM Customer
If Net < 0 (Negative): → Liability = Gross Amount Due TO Customer
### Key Definition: Progress Billings
Progress billings = Total amounts billed by the contractor (regardless of whether the customer has paid yet).
```
Progress Billings = Amounts already received + Amounts billed but not yet received
```
Do NOT use only cash received — use total billed.
### Intuition
- Due FROM customer (asset): You have done more work than you have billed → customer owes you.
- Due TO customer (liability): You have billed more than the work you have completed → you owe the excess back.
### Changes in Estimates — Prospective Treatment
Revisions to contract revenue or costs are treated as changes in accounting estimates (AS 5) and applied prospectively. No restatement of prior periods.
