Project budgets and time tracking

A project budget connects agreed work with the time and money needed to deliver it. Record hours against that work, capture other costs and regularly estimate what remains. Compare the forecast final cost with the approved cost budget; spending to date alone cannot show whether the project is likely to finish within it.

Keep the measures distinct

Hours reveal changing effort; money is needed to judge a cost budget. Neither is automatically the amount a client can be billed. A billable rate is a client charge, while an internal cost rate describes the cost of providing the work. A fixed fee can stay unchanged while delivery hours rise.

Set a budget that time records can explain

Divide the approved work into a few recognisable work packages. For each, record expected effort, the people or roles involved, the cost basis and planned external expenses. State the currency, period and costs covered by the budget.

Keep the approved estimate separate from later forecasts. When scope changes, record the authorised decision and its effect on effort and cost. Replacing the original estimate whenever work takes longer removes a useful comparison.

Time entries should identify the project, work package, date, person and duration. For client work, record whether each entry is billable under the engagement rules. Non-billable work can still consume staff time and internal budget. Descriptions should let a reviewer identify the work without reconstructing it from memory.

Review what has happened and what remains

Choose a regular cut-off and check for late or missing time and expenses. Include relevant supplier costs and commitments. Ask each work owner for a fresh estimate of effort remaining. The remaining estimate is not necessarily the original allowance minus hours logged.

Compare the recorded hours with the fresh estimate of effort remaining to form a working hours forecast. To forecast cost, apply the appropriate internal cost rates and add remaining non-labour costs, taking care not to count a commitment twice.

Check what a software budget display measures. A fee display based on billable rates is not an internal cost forecast. Retain an approved reference outside an editable budget figure if you need to preserve the original plan.

Connect the cost inputs

A project cost view can combine the budget with purchase orders, timesheets, supplier invoices, materials and financial reports.

Use the connected view to compare planned and actual costs, while finance checks commitments, variations, purchase approvals and invoice status. These are related but different records: an approved purchase may be a commitment before its invoice is recorded, so keep their status visible when updating the forecast.

Costs can also cross procurement, inventory, HR, billing and accounting workflows. When checking a system or a manual process, trace how an input from each relevant workflow reaches the project cost view, and check that the forecast covers the same project scope as the budget and time records.

Check the cost data flow

During a software demonstration, test how a corrected or reversed source entry is reflected in the project view, and whether you can identify the source behind a displayed cost. This helps check that the figures can be verified against the underlying records.

If the organisation uses an ERP, establish which system is authoritative for each cost record and how discrepancies between that record and the project view are resolved.

Turn a forecast into a decision

A useful review shows the approved cost budget, actual cost, distinct outstanding commitments, estimated other remaining cost and forecast final cost for the same scope. When the forecast rises, identify the affected work package and cause: an estimate that missed work, rework, an approved change, a rate change or an external expense.

Agree who may change scope, staffing or the budget. Present the effect of each practical option while there is room to act, then record the authorised decision and update the forecast. A threshold alert can prompt a review, but an actual-usage alert will not necessarily detect rising costs in work that remains.

When assessing software, ask a candidate to show one small project from estimate through logged time, an expense, a revised remaining estimate and an approved change. Check the display's measure, treatment of non-billable work, rate and permission rules, and whether the original budget remains identifiable. Confirm the behaviour on the plan and roles you intend to use.
