What it means

What this means

What it is

Retainer invoicing bills a set monthly fee in advance, coupled with detailed reports of the actual tracked hours delivered against that allowance.

Who needs this

Marketing agencies, IT support firms, and lawyers who charge clients recurring monthly retainers and must account for their hours.

The problem

Calculating retainer overages by hand is a billing bottleneck

If you bill a set retainer but track overages separately, compiling the monthly invoice is complex. You must calculate the hours worked, check if they exceeded the retainer limit, and bill the overage hours at different rates by hand.

Sound familiar?

Signs this is happening on your team

  • Finance manually reviews logs to find retainer overages
  • Clients dispute overage charges because they lack reports
  • Recurring retainer invoices are delayed by timesheet checks
  • Retainer hours and overage billing are calculated separately
  • You forget to bill overages because checking is too complex
The cost

What this costs you

Poor retainer billing processes delay recurring revenue, lose money from unbilled overages, and cause client distrust due to unclear timesheets.

The solution

Automated recurring retainer invoicing and reports

TimeTracker automates retainer invoicing. It bills the set fee on a schedule, compares actual hours to the retainer limit, calculates overages at contract rates, and appends detailed timesheets automatically.

FAQ

Frequently asked questions

How does the system calculate overage billing?
Once actual hours exceed the retainer limit, any additional hours are multiplied by the override overage rate and added as a line item.
Can we bill retainers in advance?
Yes. You can configure invoices to bill the flat retainer at the start of the month, and bill overages at the end of the month.
Does it support tiered retainers?
Yes. You can set up custom tier structures where rates adjust as the client consumes more hour blocks.
Can we roll over unused hours?
Yes, you can configure rollover rules that transfer unused retainer hours to the next billing cycle.
