If it is agreed to with the contracting officer, then a contractor can incrementally bill the Government for an item it has purchased under a cost reimbursement incrementally funded contract. The contract would have a clause that would dictate what happens if the contract is not fully funded. The cost must comply with 52.216-7, Allocable Cost and Payment and the contractor must comply with clause 52.232-22, which should be in the contract.
Incremental billing is not part of the cost accounting standards that I could find below in 48 CFR 9903.302-1.
The Three Areas of Cost Accounting (48 CFR 9903.302-1) Measurement of Costinvolves the methods and techniques used in defining the components of cost, determining the basis of cost measurement, and establishing criteria for use of alternative cost measurement techniques. Examples of cost measurement are listed below:
- The use of historical cost, market value, or present value;
- The use of standard or actual cost; or
- The designation of items of cost which must be included or axcluded from tangible assets or pension cost.
Assignment of cost to cost accounting period refers to the method used in determining the amount of cost to be assigned to individual cost accounting periods. Examples are the requirements for use of accrual basis or cash basis accounting.

- The accumulation of costs;
