From recorded hours to a clearer invoice

A good week deserves a clear finish

Imagine a contractor who has completed the week’s work. The client is pleased with the support, the consultant is planning the next assignment, and the operations team is preparing the paperwork. This is a useful moment to connect the story of the work to the record that will support the invoice.

For recruitment agencies running contract or temporary desks, the timesheet-to-invoice process crosses several responsibilities. The opportunity is to make each handover easy to understand: what work was recorded, who approved it, and which agreed terms apply. That clarity starts before anyone presses “generate invoice”.

Here is a practical approach to review with your team. It focuses on the operational handover, with a simple aim: help colleagues follow the source of an invoice without reconstructing the whole working week.

1. Agree what a complete timesheet looks like

A timesheet is more useful when everyone understands what belongs in it. Before an assignment starts, explain the period being recorded, the submission timetable and who can help with questions. Make the expected unit clear too: an agreed day and a recorded hour are different pieces of information.

Check that the submission relates to the correct assignment and working period. Where your process records breaks or separate categories of work, explain how those should be entered. A short example can make expectations easier to follow than a long instruction sheet.

Consider an illustrative handover: “Please submit this week’s hours against the current assignment by the agreed cut-off. Your nominated client approver will review them. If anything needs correcting, the operations contact will explain the next step.” Adapt the wording to the actual arrangement; the value is in making the route visible.

2. Keep approval distinct from submission

Submitting time says that a record is ready to be checked. Approval says that the designated reviewer has accepted it through the agreed process. Keeping those stages distinct helps colleagues understand what is ready for the next step and what still needs attention.

Agree who reviews the time, how cover works during absence, and where questions should go. If a reviewer needs a correction, give a specific explanation so the contractor knows what to revisit. The goal is a clear conversation around the record.

An agency can make this practical with a short daily review of outstanding submissions and approvals. Look for the item that needs an action and the person best placed to take it. A queue is most useful when it leads to a next step, rather than becoming another list to circulate.

3. Carry the agreed terms into the handover

Approved time is one part of the billing picture. The assignment’s agreed rates, units and dates also matter. Before an invoice moves forward, the person checking it should be able to trace those details to the relevant assignment and approved time record.

For example, a consultant may have agreed an extension while an operations colleague is reviewing the latest timesheet. A connected record gives them a place to check which terms belong to the work being billed. It is still important to confirm that the recorded agreement is accurate.

Choose a simple check for your team: can a colleague explain what period the invoice covers, which approved time supports it and where its terms came from? If any answer requires searching through several conversations, that is a useful place to improve the handover.

4. Give changes a visible route

Sometimes a time entry or an assignment detail needs correcting after an invoice has been prepared. Agree how your team identifies the affected record, reviews the change and follows the appropriate correction process. Keep the original context available so colleagues can understand what happened.

Avoid treating a corrected source record as proof that every document based on it has also been updated. Check the relationship explicitly. The person making a change should know who needs to review its effect before the invoice continues through the workflow.

Use a brief team review to look for recurring questions: unclear units, missing approval cover, or changes that reach operations late. These are opportunities to refine the shared process. Choose one improvement at a time and check whether it makes the next working week easier to follow.

How Rekro connects the process

For agency workspaces, Rekro links contractor timesheets to assignments and authorised client review. Its invoicing capability can generate client and self-billing invoices from approved timesheets on eligible contract or temporary assignments, with invoice workflows and approval gates. Automatic generation depends on the agency’s settings; approval alone does not mean an invoice has been sent.

Self-billing also requires the appropriate agreement with the supplier. HMRC’s UK VAT guidance sets out agreement, record-keeping and invoice requirements; generating a document in software does not itself establish that those conditions have been met.

Rekro also tracks changes to billing source information so affected invoices can be reviewed through the appropriate regeneration or reissue process. The team remains responsible for checking the agreed terms and choosing the correct action. These invoicing capabilities apply to agency workspaces, rather than internal workspaces staffing their own projects.

Start with one assignment and follow its latest working period together. Can the consultant, approver and operations colleague all find the same source information? A clearer answer is a useful foundation for a more consistent timesheet-to-invoice process.
