Replacing Excel for Timesheet Approval in Facilities Management

Facilities Management organisations may use Excel for timesheet approval because it is quick to adapt and can hold the information the team needs without waiting for a new software project. In this setting, work is organised around buildings, sites, assets, service requests and contracted activities, often with several teams sharing responsibility.

That flexibility is useful, but the spreadsheet can gradually become more than a file. It may start coordinating time entries that need to be assigned to the right job, project or activity and then reviewed before downstream use. At the same time, CAFM, maintenance, finance or contractor platforms may cover standard processes while Excel fills contract-specific or customer-specific gaps.

This guide is about recognising that point and choosing the proportionate next step. The answer may be a better workbook, an existing software product, an extension to a system already in use, or a custom app built around the actual workflow.

How timesheet approval is usually handled in Excel

Timesheets in Excel often use one sheet per person or week, with dates, hours, project or job codes, notes and an approval indicator maintained separately. Typical information can include person, date, job or project, activity, hours, notes and approval status.

In facilities management, the workbook often sits inside a wider process rather than operating on its own. updates often need to happen at the building or asset rather than only from an office. Requests and planned work can pass between service desk, internal teams, contractors and client contacts.

That surrounding work matters because a spreadsheet may be perfectly capable of storing the rows while still being a poor place to coordinate every decision, hand-off and update.

Where the spreadsheet starts to break down

The useful question is not whether Excel can technically hold more data. It is whether the team is doing increasing amounts of manual coordination around the workbook.

Common failure points for timesheet approval include:

• staff submit files in different formats
• job codes are typed inconsistently
• approvers cannot see what is still missing without checking several sheets
• corrections are made after approval with little visibility
• finance or operations has to consolidate files before reporting

The sector adds its own practical pressure. Photos, completion notes, certificates, job sheets or site documents may need to stay with the relevant work record. Managers may need views by building, contract, asset, work type, contractor or status.

Signs you have outgrown Excel

A spreadsheet is more likely to be acting as an operational system when several of these are true:

• weekly chasing is needed to collect timesheets
• several files must be merged for reporting
• approvers sign off by email
• people use old project codes
• corrections require reopening and resending spreadsheets
• one person has become the keeper of the workbook and the rules around it
• staff maintain side lists, emails or messages because the spreadsheet does not cover the whole workflow

These are not arbitrary limits. A workbook with many rows can be completely manageable, while a smaller file can be difficult if it has to coordinate several people, permissions, decisions and external systems.

When Excel is still suitable

Excel can be sufficient when a small number of people submit simple time records to one reviewer and consolidation is not burdensome.

It is also worth improving the workbook before replacing it if the main problem is inconsistent structure. Controlled lists, clearer ownership fields, protected calculations, better naming and a single shared location can remove a surprising amount of friction.

Excel can remain valuable after part of the workflow moves into an app. Teams may still use it for flexible analysis, modelling, ad-hoc reporting or data exports where a grid and formulas are the right tool.

What a better workflow could look like

A replacement should not copy the spreadsheet cell by cell. It should make the real route through timesheet approval clear and give each person the information and actions they need.

1. Enter time against controlled work codes

Give staff a simple way to record hours using current projects, jobs or activities rather than free typing. For facilities management, this should reflect that work is organised around buildings, sites, assets, service requests and contracted activities, often with several teams sharing responsibility.

2. Check completeness before submission

Flag missing or obviously incomplete entries while the person still has the context to correct them. The design should make sense for service desk staff, facilities managers, engineers, cleaners, contractors, supervisors and client teams, rather than assuming one office-based owner.

3. Submit a period for review

Freeze the submitted version for review so the approver knows what is being signed off. This is especially useful where requests and planned work can pass between service desk, internal teams, contractors and client contacts.

4. Approve or return with a reason

Keep review comments and corrections against the same period instead of moving between email and separate files. Where evidence is part of timesheet approval, photos, completion notes, certificates, job sheets or site documents may need to stay with the relevant work record.

5. Report from approved time

Use approved records for project, job or management reporting without manually merging workbooks. The resulting data should support the views people actually need: managers may need views by building, contract, asset, work type, contractor or status.

What is different about timesheet approval in facilities management

Facilities time records may need to distinguish contract work, site attendance, reactive jobs or internal activity. The operational difficulty is often collecting consistent coding from mobile staff and giving supervisors a manageable approval view across several locations. A replacement should reduce consolidation while keeping downstream payroll or billing systems authoritative.

Failure patterns specific to this setup

• The replacement still fails if it does not limit time entry to current contracts, sites or work codes that matter to the business
• The replacement still fails if it does not allow supervisors to review the staff and locations they are responsible for without one company-wide sheet
• The replacement still fails if it does not keep rejected entries and correction reasons visible before approved time is exported

Practical details to design around

• Limit time entry to current contracts, sites or work codes that matter to the business.
• Allow supervisors to review the staff and locations they are responsible for without one company-wide sheet.
• Keep rejected entries and correction reasons visible before approved time is exported.

Where the system boundary should sit

Payroll, finance or workforce systems should remain responsible for pay and billing where they already do so. The app should provide approved, consistently coded time to those systems rather than duplicate them.

Approval design lens

For timesheet approval in facilities management, the difficult part is rarely storing the rows. It is deciding who can submit, what information makes a request complete, who has authority to decide, what happens when something changes, and which approved data moves onward. A useful replacement should make those decisions visible rather than hiding them in email.

What good looks like

• People enter time against current, controlled work codes.
• Missing and incomplete submissions are visible without a separate chase spreadsheet.
• Approvers can return entries with a reason and see the version they reviewed.
• Only approved time flows into downstream reporting, costing, payroll or invoicing.

The process should also pass the combination-specific proof points below:

• Reconcile one complete pay or billing period with the existing outputs.
• Test staff who work across more than one contract in the same week.
• Prove supervisors can return individual entries without rejecting an entire file.

Questions to answer before replacing the spreadsheet

• Which jobs, projects or activities are valid for each person?
• What must be checked before a period can be submitted?
• Who approves time and what should happen after a correction?
• Which downstream system or report consumes approved time?

These questions should be answered with the real workbook, users and surrounding systems in front of you. They are more useful than choosing software from a feature list before the awkward parts of the workflow are understood.

A more specific hypothetical scenario

Consider engineers submitting separate weekly spreadsheets for several contracts. The app gives each engineer current site and work-code choices, shows supervisors who has not submitted, and creates one approved dataset for the downstream payroll or contract-reporting process.

This scenario is illustrative and is not a customer case study.

What not to build

• Do not rebuild payroll calculations when approved time only needs to be handed over.
• Do not import obsolete job codes simply because old spreadsheets contain them.
• Do not make every user navigate project-management features when they only need to enter and submit time.
• Do not duplicate a function already handled well by an existing system merely to make the new app look more complete.
• Do not move every old spreadsheet column into the new system unless it has a clear operational purpose.

Comparing the realistic replacement options

The cheapest-looking option is not always the lowest-cost operating model. Compare the amount of coordination, configuration, duplicated entry and compromise each option leaves behind.

Option	Why it can look attractive	The tradeoff to examine
Keep or improve Excel	Familiar, flexible and already paid for	Individual spreadsheets are familiar, but collection, consolidation, code cleanup and approval history become the hidden workload.
Buy an off-the-shelf product	Established product and a defined implementation route	Time-tracking products are attractive for standard projects and approvals. They become less compelling where job structures, costing rules or submission logic are specific to the business.
Extend an existing core system	Keeps more data inside a platform the business already uses	Project, payroll or field-service systems may already capture time, but extending them only helps if users can enter the right codes and the approval flow matches reality.
Build a custom app	Designed around the workflow the business actually follows	A custom app can keep time entry deliberately simple while applying the exact work-code, submission and approval rules needed downstream.

For timesheet approval in facilities management, the system boundary matters particularly strongly. Payroll, finance or workforce systems should remain responsible for pay and billing where they already do so. The app should provide approved, consistently coded time to those systems rather than duplicate them.

A specialist product or existing module is still the right answer when the workflow genuinely fits it. The custom-app case becomes stronger when the spreadsheet exists precisely because the surrounding software cannot represent the organisation's rules, calculations, approvals, hand-offs, evidence or reporting without workarounds. In that situation, buying another generic product can leave the business paying for software while Excel continues beside it.

The Spreadsheet Assessment is the lower-commitment way to test that fit before agreeing a build. The recommendation can still be to keep Excel or use existing software if that is genuinely the better route, but the assessment is designed to identify whether the spreadsheet is filling a business-specific gap that deserves its own app.

What to include in a replacement system

A sensible first version should concentrate on the parts of timesheet approval that people use repeatedly. Useful capabilities may include:

• controlled job codes
• daily or weekly entry
• submission status
• approval and return
• locked approved periods
• exception views
• reporting and exports

For facilities management, the design should also account for the way work is actually performed. Updates often need to happen at the building or asset rather than only from an office. Access and screen design should reflect service desk staff, facilities managers, engineers, cleaners, contractors, supervisors and client teams rather than assuming every user needs the same view.

Features should earn their place. If a rare exception can remain manual without creating risk or confusion, it may be better to leave it out of the first release and keep the core workflow simple.

Hypothetical example

Consider a hypothetical facilities provider supporting several buildings and service teams where staff send weekly spreadsheets to a manager who checks them and combines approved hours for reporting. The spreadsheet is useful because it fills a gap, but staff have to keep the file synchronised with the work happening around it.

A replacement could change that flow so time can be entered against current work codes, submitted for review and reported directly once approved. The exact screens and rules would depend on the organisation, but the important shift is that the record becomes part of the workflow rather than a document someone has to update after the workflow has happened.

This is an illustrative scenario, not a customer case study and not a claim about a particular organisation.

Migration checklist

Before replacing the spreadsheet, work through the details that make the current process function:

• agree active project and job codes
• decide how open periods are handled
• confirm which historical time needs migration
• test corrections after submission
• reconcile the first approved period against the old process
• map the people and hand-offs involved in facilities management
• identify information that already comes from another system and should not be re-entered unnecessarily
• preserve important calculations and business rules with representative test cases
• decide what old data genuinely needs to move and what can remain archived
• agree a clear cut-over point so the spreadsheet and app do not become competing operational records

The Spreadsheet Assessment is designed to work through this kind of detail before a build is agreed. It looks at the spreadsheet together with the process around it so the recommendation can distinguish between what should stay, what should change and what a first useful version would need.
