Milestone Invoices That Fire
When the Milestone Does.
LedgerUp reads phased billing schedules out of signed contracts and generates each milestone invoice on trigger — date-based, deliverable-based, or approval-based — without a spreadsheet tracking any of it.
Spreadsheet milestones vs automated milestones
Milestone billing is where manual invoicing breaks down hardest — every contract has its own schedule, and every schedule lives in someone’s head.
Without automation
- Billing schedules tracked in a spreadsheet per project
- Milestone completions communicated by Slack ping — or not at all
- Invoices go out weeks after the milestone actually hit
- Percent-complete and holdback math done by hand, differently each time
- Nobody can say how much contracted revenue is unbilled right now
With LedgerUp
- Billing schedule extracted from the contract or SOW at signature
- Each milestone invoice generated on its trigger — date, deliverable, or approval
- Percent-based splits, deposits, and holdbacks computed from contract terms
- Invoices land in QuickBooks, NetSuite, or Stripe with correct line detail
- Unbilled contracted revenue visible across every open project
How milestone billing works
From signed SOW to the final milestone invoice — on schedule, every phase.
Ari reads the billing schedule at signature
When a contract or SOW is signed in DocuSign or PandaDoc, Ari extracts the payment structure: deposit, milestone amounts or percentages, trigger conditions, and net terms per invoice. The full schedule exists in the system from day one.
Triggers armed per milestone
Date-based milestones fire on the calendar. Deliverable- and approval-based milestones fire on a signal — a project stage change in your CRM, or a one-click confirmation from the project owner in Slack.
Invoices generated with the right math
Each invoice carries the correct milestone amount — percent-of-total splits, deposit credits, and holdbacks applied per the contract — with line items that reference the milestone so customers recognize what they’re paying for.
Collections and revenue tracking follow automatically
Each milestone invoice enters the standard reminder and collections workflow, and unbilled-versus-billed contract value stays visible per project — so nothing contracted goes uninvoiced.
Works with your existing stack
LedgerUp connects to the tools you already use — no migration required.
Milestone billing use cases
How teams with phased contracts bill with LedgerUp.
Agencies Billing Against SOWs
Deposit on signature, progress payments per phase, balance on delivery — Ari runs the whole schedule per SOW, across every concurrent project, with variable schedules per client.
A 40% / 40% / 20% SOW bills its deposit at signature, its second invoice when the project owner confirms phase two in Slack, and its balance on delivery.
Implementation Fees on SaaS Contracts
Enterprise SaaS deals often pair a subscription with a phased implementation fee. Ari bills the subscription on its cycle and the implementation milestones on theirs — one contract, two schedules, zero spreadsheets.
A $120K ARR contract with a $30K implementation billed 50/50 at kickoff and go-live runs both schedules automatically.
Milestones Layered on Subscriptions
Adding milestone components to a subscription model usually means manual side-billing. Ari treats milestones as first-class schedule items alongside recurring charges.
A customer’s monthly platform fee bills on the 1st; their custom-development milestones bill as each is approved — all on one coherent account.
Milestones are one billing model of several
Ari handles subscription, usage, and milestone billing — including contracts that mix all three.

Common questions about automating milestone billing with LedgerUp.
What milestone trigger types are supported?
Three: date-based (bill on March 1), deliverable-based (bill when phase two completes, signaled from your CRM or project workflow), and approval-based (bill when a named owner confirms, typically one click in Slack). Contracts can mix trigger types across their schedule.
How does Ari get the billing schedule right from the contract?
Ari extracts the payment terms section from the signed agreement — amounts or percentages, trigger conditions, deposit and holdback language — and presents the parsed schedule for a human confirmation on the first contract of each shape. After that, similar contracts run automatically.
Can milestone invoices have different payment terms than each other?
Yes. A deposit due on receipt, progress invoices at net 30, and a final invoice at net 45 within one contract are all handled — each invoice carries its own terms and enters reminders on its own clock.
What about deferred revenue on milestone contracts?
Milestone billing and revenue recognition are related but distinct — an invoice fired is not revenue earned. LedgerUp tracks both the billing schedule and the recognition treatment, so milestone contracts stay clean under ASC 606. See the revenue recognition solution for the full picture.
What happens when a project timeline slips?
Deliverable- and approval-based milestones slip with the project automatically — they fire on the signal, not the original date. Date-based milestones can be adjusted, and the change is logged with who moved it and why.
Which systems do milestone invoices post to?
QuickBooks, NetSuite, Sage Intacct, Xero, or Stripe — with milestone-level line detail and project references, so your ledger shows what was billed against which phase of which contract.
