The timesheet problem no one talks about
In staffing and consulting firms, approved timesheets are not just an attendance record — they are the source document for client invoices. When timesheets live in one system and billing lives in another, reconciliation becomes a weekly manual exercise that introduces errors and delays payment by days or weeks.
Best practice 1 — One timesheet entry per project/client
Employees who work across multiple clients in a week must submit per-client entries. This is the only way to produce accurate billable breakdowns. A single aggregate "40 hours worked this week" entry is useless for billing purposes.
Best practice 2 — Same-week submission
Memory degrades fast. A timesheet submitted on Friday is accurate; a timesheet submitted the following Wednesday is a guess. Build a culture (and a policy) of submitting timesheets by end of business on Friday. LeafyOps HRMS sends automated reminders to employees who have not submitted by the configured deadline.
Best practice 3 — Approval hierarchy matches billing authority
The person who approves a timesheet is implicitly signing off on a billing claim. Make sure the approval chain reflects who actually has authority to commit billable hours — typically the project manager or client engagement lead, not just the direct line manager.
Best practice 4 — Never duplicate approved data
Once a timesheet is approved, the hours should flow directly into the billing and payroll systems without anyone copying them. Any manual step between approval and invoice is an opportunity for error. In LeafyOps, approved per-client hours arrive in the Accounts module as ready-to-invoice line items. The hours are never re-entered.
Best practice 5 — Lock submitted periods
Once a billing period has been invoiced, the underlying timesheets must be locked. Allowing retroactive edits to approved timesheets breaks the audit trail and creates reconciliation nightmares at year end.
How LeafyOps handles this end to end
In LeafyOps HRMS, the timesheet calendar shows the week as a grid. Each row is a client or project. The employee logs hours per day per project. The submission goes to the approval queue; the approver sees the breakdown and approves or rejects with a comment. Once approved, those hours are available in LeafyOps Accounts as billable lines on the client record — ready to become an invoice in one click.
For consultant-heavy operations, per-consultant timesheet sheets are available. Clients can be given a read-only portal view of the hours billed against their account, which dramatically reduces billing disputes.
