02 / ONE JOB. EVERY MILESTONE.

THE IRON STANDARDProgress, on paper.
MILESTONE BILLING
Bill for the stage.
Keep sight of the whole job.
A single payment doesn’t fit every project. Start with a deposit, invoice for completed milestones, and close out the remaining balance when the work is done.
- Choose deposit, progress, or final billing
- Keep each invoice connected to its job
- See how the next invoice fits the project
BALANCES & REPORTING
Less guesswork.
Every balance accounted for.
Keep paid, outstanding, and overdue invoices in view. Review customer balances and receivables so your next follow-up starts with the facts.
- Filter invoices by payment status
- See the balance for each customer
- Explore receivables and financial reports
