Why Invoicing & Payments Stalls When Billable Time Never Reaches the Invoice

Symptom: Timesheets close on Friday but invoices go out three weeks later, so the agency funds a month of contractor payroll before a single client payment lands. Root cause: Time capture and invoice generation live in separate systems with no scheduled sync, so the handoff depends on a person remembering to export and re-key.

Invoicing Payments
How do you recognize it?
  • •Timesheets close on Friday but invoices go out three weeks later, so the agency funds a month of contractor payroll before a single client payment lands.
  • •Project managers reconcile hours in Harvest while finance rebuilds the same numbers in Xero, and the two totals disagree by 5 to 15 percent at month end.
  • •Write-offs appear at invoice review: line items get trimmed because nobody can defend what the hours were for.
  • •Clients dispute scope on the invoice rather than at kickoff, adding a two-week back-and-forth that pushes DSO past 60 days.
  • •Utilization reports look healthy while cash on hand tightens, because tracked hours and billed hours are two different numbers nobody reconciles.
Why does it happen?
  • •Time capture and invoice generation live in separate systems with no scheduled sync, so the handoff depends on a person remembering to export and re-key.
  • •Agencies bill on retainer or fixed fee, which removes the forcing function that would otherwise push tracked hours into a line-item invoice.
  • •Approval sits with account leads who treat invoicing as month-end admin rather than a delivery milestone tied to project close.
  • •Rate cards, currency, and tax rules are configured per client in the billing tool but not in the time tool, so automated conversion produces invoices finance has to correct.
How do you fix it?
  • •Set a hard rule that any project marked complete triggers an invoice draft within 48 hours, and assign one named owner per client account.
  • •Run a weekly 30-minute reconciliation between tracked hours and unbilled amounts, and treat any gap older than 14 days as an escalation item.
  • •Turn on automated payment reminders at day 7, 14, and 30 in the billing platform, and stop sending manual follow-ups that slip during busy delivery weeks.
  • •Move deposit collection into the booking step using a tool like Hardbook so the first payment clears before work starts, not after the first invoice.
