A timesheet approval workflow is the set path a time entry follows from submission to payroll: an employee logs hours, a manager reviews and approves or rejects them, and only approved time becomes a locked, auditable record ready for payroll or billing. Get this path right and payroll runs on accurate numbers, disputes drop, and you have a paper trail if anyone ever asks questions. This guide covers how to set the process up, where it breaks, and how to fix it.
TL;DR:
- Most delays occur when approvers are missing or when escalation rules are not properly set, causing approval bottlenecks and unapproved timesheets sitting idle.
- Establishing clear approval deadlines, automated reminders, and fallback approvers are critical to preventing approval slowdowns and missing submissions.
- Using direct payroll integrations or validated CSV templates ensures the approved timesheets reach payroll accurately, minimizing manual re-entry errors.
- Automating routing, reminders, and escalation can significantly reduce manual handling, but a human review should still oversee unusual or flagged entries.
- Start small with simple workflows, automate core alerts, and adjust based on real manager feedback rather than overloading with features.

The core stages of a timesheet approval workflow
Every functioning workflow follows the same basic shape, whether it runs on a spreadsheet or a dedicated platform: submission, review, decision, then export. Tempo’s guidance on timesheet approvals describes this as time entries moving through manager review, optional multi-level sign-off, and final authorisation before feeding into payroll or billing.
The submission stage defines the period, usually weekly or fortnightly, and gives employees a fixed window to log hours before the cut-off. Review sits with a direct manager or project lead, and larger teams often add a second layer, for example a finance approver who checks project codes before the entry becomes billable.
At the decision point, a timesheet is either approved and locked, or rejected with a note explaining what needs fixing. That note matters more than most managers realise: a vague rejection just bounces the problem back without solving it.
- Submission: employee logs hours within a defined period, before a fixed deadline
- Review: manager or project lead checks entries for accuracy and completeness
- Decision: approve (locks the record) or reject (returns it with a correction note)
- Export: approved time flows to payroll, billing, or both
Every action in that chain, submission, edit, rejection, approval, needs a timestamp and an actor attached to it. Without that audit trail, you cannot answer a basic compliance question: who approved this, and when.
Setting up approval routing, deadlines and escalation
Building the workflow itself is mostly a mapping exercise, not a technical one. You are deciding who approves what, by when, and what happens when nobody does.
- Map every employee to an approver. Assign a primary approver for each person or team, and name a fallback approver for when the primary is on leave. Gaps here are the single most common reason timesheets sit unapproved for a week.
- Set the submission window. Decide when the period closes (commonly end of Friday or end of the last working day) and communicate it clearly.
- Set a manager SLA. A workable cadence, drawn from common workflow guidance, is: employee submits by the end of the period, manager approves within a fixed window such as by Monday noon, and any rejection gets corrected within 24 hours before resubmission.
- Build escalation rules. If a timesheet sits unapproved for 48 hours, route it automatically to the fallback approver or their manager.
- Turn on reminders and bulk approval. Automated nudges catch the timesheets managers forget; bulk approval lets them clear routine entries in seconds rather than one click at a time.
Pro Tip: Keep the submission form to the minimum required fields. Every optional field you add is one more reason an employee submits late or leaves something blank, which then bounces back to you as a rejection.
Best practices that keep the approval queue moving
Speed and accuracy in approvals usually come down to a handful of habits rather than a big platform decision.
Exception-based review is the biggest one. Rather than reading every line of every timesheet, scan for the entries that actually carry risk: overtime, unplanned absence, or hours logged against an unusual project code. Everything else gets a quick approve. This is roughly what TimeTally’s workflow guidance recommends when it frames review as exception handling rather than a line-by-line audit.
Bulk approval and one-tap actions work well once you trust the data behind them, but pair them with a flag on anything outside normal ranges so bulk approval never silently waves through an error.
- Standardise rejection messages so employees get a consistent, specific reason every time
- Set a short, fixed correction window (commonly 24 hours) rather than leaving it open-ended
- Keep one system as the single source of truth, not a spreadsheet plus an app plus email threads
- Maintain a versioned audit trail so every edit, rejection and approval is timestamped
A tight correction window and a clear rejection reason, according to Timewize’s workflow research, are what actually cut down rework, more than any extra approval step you might add.
Where timesheet approval workflows usually break down
Most delays trace back to four recurring problems, and each has a fix that takes an afternoon to put in place, not a system overhaul.
- Slow approvals: set a firm deadline, send managers a daily digest of pending items, and escalate automatically past 48 hours.
- Missing submissions: automated reminders at 24 and 48 hours, plus a hard cut-off that flags the gap rather than letting it slide.
- Manual payroll handovers: replace copy-paste handovers with a direct integration or, failing that, a standardised CSV template.
- No audit trail: require every action, submission, edit, rejection, approval, to be logged with a timestamp and a note.
Manual, email-and-spreadsheet approval chains are where most of this breaks down in practice. Toggl’s analysis of timesheet approval challenges points to exactly this pattern: delays and lost auditability build up because nobody automated the routing.
Pro Tip: If one approver is consistently the bottleneck, that’s a routing problem, not a discipline problem. Add a fallback approver or shorten their SLA rather than chasing them weekly.
Getting approved time into payroll and billing correctly
Approval only has value if the locked record actually reaches payroll or billing without someone re-typing it. A direct payroll integration is the strongest option; where one isn’t available, a structured CSV template is the reliable second choice, according to Timewize’s guidance on timesheet workflows.
Before you trust any export, map your pay items, project codes and billable flags in advance, so overtime, leave and standard hours land in the right columns every time rather than getting reclassified after the fact.
- Prefer a direct payroll integration over manual file handling
- If no integration exists, use a validated, structured CSV template
- Map pay items, project codes and billable flags before the first live export
- Log every export with the actor, timestamp and the period it covers
- Run at least one test payroll export before relying on the process at scale
Some platforms, including enterprise systems documented in SAP’s timesheet approval configuration notes, allow approval and escalation rules to be centralised system-wide, which is worth knowing if your organisation is weighing a platform-level rollout against a lighter, workflow-specific tool.
How FlowLab scopes a tailored approval workflow for an SME
A tailored approval workflow starts with an operational conversation focused on who approves what, the number of staff, and existing payroll systems. From there, three paths open up: configure an existing module, adapt a proven workflow foundation, or build something bespoke.
- Configuration suits teams whose approval chain is simple and standard
- Adaptation fits businesses needing custom fields, routing or SLAs on a known base
- A custom build makes sense when payroll or ERP mapping needs real integration work
A pragmatic view on rolling out approval workflows
Deadlines, an audit trail and correct exports matter more than a long feature list. Start small, roll out to one team, and adjust based on what managers actually complain about. Automate reminders and escalation freely, but keep a human reviewing anything unusual. Feature-chasing wastes budget that should go on getting the basics reliable first.

A practical next step if you’re weighing your options
There are alternatives to a costly platform overhaul for SMEs setting up a timesheet approval workflow: they can get a workflow scoped to the actual approval chain, not a licence for features that may never be used. A complimentary app fit review can look at how the team currently submits and approves time, then indicate whether a ready-made module, an adapted product, or a custom build is the most economical route to a working process.
If attendance data already feeds your payroll decisions, PresenceFlow is worth a look as an attendance-to-payroll starting point. Where the gap is genuinely a payroll or ERP mapping problem, Flowlab’s ERP integration and workflow systems work covers that directly. For teams past the point where configuration alone will do, the app development service for Singapore SMEs is the next step: book the free review and find out which route actually fits before committing to a build.

FAQ
What is timesheet approval?
Timesheet approval is the review step where a manager checks an employee’s submitted hours for accuracy, then approves or rejects them before the record locks and moves to payroll or billing.
How do I create an approval workflow?
Map each employee to a primary and fallback approver, set a submission deadline and manager SLA, add escalation rules for unapproved timesheets, and turn on reminders and bulk approval.
What are the steps in the approval process?
The standard sequence is submission within a set window, manager review, an approve or reject decision with a note, and export of the locked, approved record to payroll or billing.
How do I approve my timecard?
You review the logged hours against actual work done, check for flagged exceptions like overtime, then approve to lock the record or reject it with a specific correction note.
Can a small business automate its timesheet approval workflow without a full platform rollout?
Yes. Many SMEs benefit from configuring reminders, routing, and escalation on existing tools; a free app fit review can confirm whether configuration is sufficient or if a custom build is worthwhile.
