On public construction projects in California, like state or municipal jobs, retained funds are limited to 5% or less prior to completion and acceptance of the project. After 95% of the work is complete, withheld funds may be reduced to 125% of the estimated value of the unfinished work.
Retainage withheld from a direct contractor must be released by 45 days from the “date of completion.” Amounts withheld by the direct contractor from a subcontractor or supplier must be released within 10 days of the contractor's receipt of any retention payment.
In construction contracts, retention is usually set at 5% of the total contract value. Meaning that each time you submit a monthly progress claim, 5% will be withheld from your receivable invoice.

In general, businesses which provide a service that does not result in a tangible good are exempt from sales tax, as it only applies to goods. For example a freelance writer or a tradesperson is not required to remit sales tax, although a carpenter making custom furniture is so required.
