Keep every hourly invoice backed by its hours
When you bill by logged hours, an invoice total only means something if you can show the hours behind it. If a client questions a number, you need the timesheet that produced it — not a hunt through old files. Recording the hours billed, the rate, and the period on each invoice, with the timesheet attached, keeps every hourly invoice defensible. Cash Workspace lets you record those fields and attach the timesheet; you enter the hours and it does not total time for you.
The problem
Why hourly invoices need their hours attached
An hourly invoice is just a total unless the hours behind it are recorded and reachable. When the timesheet lives elsewhere, every query becomes a search.
- A client asks what the 14 hours covered and you can't find the timesheet.
- You can't tell which billing period an invoice's hours came from.
- The rate on an old invoice is unclear, so the total can't be re-checked.
- Hours logged in one tool and invoices in another never reference each other.
- At year-end you have invoice totals but no hours to back them up.
The workflow
Record hours with every invoice
Enter the hours billed, the rate, and the period on each invoice, and attach the timesheet that produced them.
- 1
Note the billing period
Record the dates the invoice covers, e.g. May 1–15, so the hours map to a window.
- 2
Enter hours billed
Record the number of hours on the invoice — you enter this figure; the workspace stores it, it doesn't sum your time.
- 3
Note the rate
Record your hourly rate for this client so the total can always be re-checked against hours.
- 4
Attach the timesheet
Save the timesheet or activity log as a document on the invoice so the hours have a source.
- 5
Set the status
Mark the invoice sent, paid, partially paid, or overdue and update it as things change.
Record structure

Common mistakes
Mistakes to avoid
- Sending an hourly invoice without recording the hours behind it.
- Leaving the billing period off, so you can't tell which window the hours cover.
- Not attaching the timesheet, so a client query means a file hunt.
- Forgetting the rate, so an old total can't be re-checked.
- Keeping hours in one tool and invoices in another with no link between them.

FAQ
Hourly billing records FAQ
- Does Cash Workspace track my time?
- No. It's not a time tracker. You log your hours in your own way and enter the total on the invoice, attaching your timesheet. Cash Workspace stores the figure and the document; it does not record or total your time.
- Does it total my hours or calculate the invoice amount?
- No — you enter the hours, the rate, and the amount yourself. The workspace keeps them on the record for review but does not multiply or sum them.
- Where should the timesheet live?
- Attach it to the invoice it produced, so if a client questions the hours you can open the supporting document straight from the invoice record.
