SolutionsTime and materials
Time and materials billing software from approved time to the invoice queue
Time and materials billing breaks when the rate is a guess. Sigmaviu takes approved timesheets, applies the rate you already stored, and lines the result up in a billing queue you can invoice.

What changes
01
Approved time only
The queue and the unbilled totals use the same rule: approved, and not excluded.
02
A rate with a source
Rates resolve from the time entry, the project resource, the org role, or the employee, and the labor row can show which one applied.
03
Milestones too
A contract schedule or a completed WBS milestone can release billable amounts into the same queue.

How Sigmaviu handles this
Interactive time
People log time on a list or a calendar. Reviewers can switch to a team view.
Expenses and work orders
Approved expenses and work can join the queue with the time.
Retainage
Billing rules can hold retainage and support partial collection on the client portal.
Recurring invoices
Schedules can issue repeating invoices when the commercial pattern is fixed.

Scope
This covers time-and-materials and milestone release into Sigmaviu invoices. It is not a full professional-services ERP or a payroll engine.
Questions buyers ask
Why do unbilled totals and the queue disagree?
They should not. Both use approved rows that are not excluded. Excluded rows can be restored from the queue.
Can the invoice go to a different client than the project?
The create-invoice path keeps the client on the billable row’s project so the bill does not drift.
Is the lookahead an invoice?
No. Marking a task billable builds a forecast. Invoicing still starts from the queue.
