Milestones plan revenue
Add a milestone to mark when work is delivered and revenue is due, then flag it billable — Monument drafts the invoice straight from the stage's calculated revenue.
You've priced the work; now you plan when it gets billed. That's what milestones are for. A milestone marks a point in the project — a stage signed off, a deliverable issued — where work is delivered and a payment falls due. And because Monument already knows what each stage earns, a milestone can turn straight into a draft invoice.
The idea: milestones plan future revenue
A milestone isn't just a flag on the timeline — it's a billing point. Each one says "by here, this much revenue should have been earned, and we expect to invoice it." Set your milestones across a project and you've drawn its whole income profile: how much, and when.
The clever part is the link back to your pricing. You spent the last few steps making each stage's revenue calculate itself from resourcing and fees. A billable milestone reads that same calculation and drafts the invoice for you — no re-keying amounts, no separate spreadsheet of what to bill when.
Add a billable milestone
- 1
Select the project and add a milestone — a planned point where work is delivered.
- 2
Flag it as billable. Monument drafts an invoice from the revenue the stage has calculated.

- 3
Save it. The milestone takes its place on the timeline, draft invoice attached.

Not every milestone is a payment — some just mark progress or a hand-off. The billable flag is what turns a milestone into money: flag it, and a draft invoice appears; leave it off, and it's purely a planning marker.
You're planning the money, not just the dates
This is the shift worth internalising: with milestones in place, your schedule is your revenue forecast. Drag the work later and the billing point moves with it; change the resourcing and the milestone's draft invoice updates to match. The plan for the work and the plan for the income are the same plan.
Gotchas
- A billable milestone with no revenue drafts an empty invoice. Make sure the stage it covers has revenue (allocations or a fee) before flagging it billable.
- Moving a stage moves its milestone. That's intended — but check the billing dates still suit the client after a reschedule.
- The draft is a draft. Nothing is sent until you approve it in Invoicing — milestones only plan the bill.
Where this fits next
Your milestones have drafted the invoices, so the plan for the work and the plan for the income are now the same plan. From here, each draft invoice waits in Invoicing, ready to review and send the moment that stage of work is delivered.
