Fees by client do not show the hours behind them. Insyto reads your time, fees and invoices together and shows which clients and projects are under-billed while there is still time to fix it.

Where the margin leaks

Four blind spots. Four fixes.

  1. 01

    Scope creeps an hour at a time.

    Insyto: Hours logged are set against each retainer and estimate, so a project running over shows while it runs, not at the post-mortem.

  2. 02

    Work gets done and never invoiced.

    Insyto: Time is matched to invoices. Hours with no invoice behind them are listed by client and month.

  3. 03

    Your busiest client may be your worst paid.

    Insyto: The effective hourly rate for every client: fees divided by the hours actually worked.

  4. 04

    Utilisation is a guess.

    Insyto: Billable against total hours, by team member and month, from the timesheets you already keep.

57%

of agencies lose $1,000 to $5,000 a month to work they never bill.
