Use case · Client billing & invoicing
Invoices clients check instead of query
You find out a project is over budget when the invoice does not add up. Burn-down runs against the rate card as the hours land, so the overrun shows up in week two instead.
Free for two seats, no card.
- Set up the commercial shapeClients, projects, tasks, budgets and rate cards, per client and per role, because a blended rate is where margin goes to hide.
- Attribute time as it happensCaptured hours map to the project and task through PM-tool tracking, so attribution is a byproduct of the work rather than a Friday exercise.

How it works
From a tracked hour to a verified invoice
- 1
Set up the commercial shape
Clients, projects, tasks, budgets and rate cards, per client and per role, because a blended rate is where margin goes to hide.
- 2
Attribute time as it happens
Captured hours map to the project and task through PM-tool tracking, so attribution is a byproduct of the work rather than a Friday exercise.
- 3
Approve, then invoice
Approved hours flow into an invoice through the shared rate engine, so the cost of the work and the price of it are computed from one implementation rather than two that drift.
- 4
Finalize and hand over the proof
Finalizing seeds a Verified Work Certificate. The client gets a link that verifies itself, with only the fields you disclose.
A line-item invoice vs. an invoice with proof attached
workmonitor.vsSpreadsheet billing
Where the hours come from
With WorkMonitor
Captured hours attributed to a project and task as the work happened, approved through a separation-of-duties chain.
Spreadsheet billing
A timesheet somebody assembled at the end of the month, from memory and a calendar.
When you learn about the overrun
With WorkMonitor
While it is happening, from a burn-down that updates against the rate card.
Spreadsheet billing
At month end, when the budget is already gone.
The client’s first question
With WorkMonitor
A certificate link. They check it themselves, and the question does not get asked.
Spreadsheet billing
"What is this line?": followed by a week of email.
Proving the work
With WorkMonitor
Selective disclosure over a zero-screenshot work-edge record, the fields you choose, and nothing else.
Spreadsheet billing
Screenshots pasted into a deck, which exposes their data to prove you did their work.
Margin visibility
With WorkMonitor
Billing analytics off the same ledger as the invoice: realisation, write-off, effective rate.
Spreadsheet billing
Revenue in one system, hours in another, and a quarterly reconciliation to find out how you did.
Next year’s audit
With WorkMonitor
WORM-anchored, RFC-3161-timestamped certificates that still verify, on a URL that still resolves.
Spreadsheet billing
A folder of PDFs whose numbers nobody can now reproduce.

The status meeting, already written
Status is normally assembled by asking. Here it is already: hours, activity, attendance and risk on one board, for one person or the whole company. Set the thresholds once and it tells you who needs you.

Straight answers
The questions we would ask in your position
Every answer here is the one you would get on a call. Open as many as you like; they stay open, so two can be held side by side.
Through PM-tool time tracking, which ties captured hours to the ticket or task they belong to as the work happens, with in-context timers inside the PM tool in beta. The alternative is attributing a month of work from memory on the last Friday, which is where both margin and client trust get lost.
An invoice, and a certificate link. Finalizing the invoice seeds a Verified Work Certificate that they open on a public page with no account, showing only the fields you selectively disclose. It carries an RFC-3161 timestamp and a signature checkable against a published key.
No, and for client work you probably should not, since proving your work by photographing your screen exposes their data. The certificate is built from work edges rather than pixels, which is both stronger evidence and a much smaller liability.
Yes. Rate cards are per client and per role, and the same rate engine that prices an invoice prices a payroll run, so the cost side and the revenue side are computed from one implementation rather than two that drift.
Billing analytics sits on the same ledger as the invoice, and the typed v1 REST API plus the warehouse connector push it into your own finance stack. Nothing here requires the invoice ledger to be the last stop.

Same record, read for a different question. Each one opens the page written for that job.
- Prove work with certificatesA finalized invoice mints a signed certificate the client checks for themselves. Selective disclosure proves the work without handing over the work.
- Track time automaticallyNo timer to start, no Friday reconstruction. Idle is split out rather than estimated, and approved hours reach payroll and invoicing without a re-key.
- Run payroll from approved hoursApproved timesheets seed the run, one rate engine prices pay and billing, an integer-cent pre-flight has to balance, and the export is gated to the owner.
Take these with you
The software is the easy part of a rollout
Here is what we would send a manager doing one for the first time: how to read a productivity number, what to say to a remote team before anything is installed, and a policy you can adopt as written.
Point it at one team for a week.
Create the account, put the agent on a handful of desks, and leave it alone. On Friday you read the week instead of reconstructing it: hours against their projects, focus and idle per person, and the timesheets already filled in.
Free for two seats. No card, and no sales call to sit through.
