Why Approval Speed Matters
Here's the reality: most finance teams spend their days chasing approvers. An expense report bounces between three people, each waiting for the last one to review it. Two weeks later, it's finally approved. Meanwhile, your team's frustrated and employees are out of pocket on reimbursements.
The good news? You don't need expensive enterprise software to fix this. A well-designed workflow using low-code tools can cut approval time from days down to hours. We've seen teams go from 7-10 day cycles to same-day approvals. The trick isn't complicated—it's about removing bottlenecks and making it easy for approvers to actually review things.
This guide walks you through building that workflow from scratch. We're talking about actual implementation, not theory. By the end, you'll have a blueprint you can adapt to your specific team structure.
The Time Difference
Most companies process expenses in 7-10 days. A streamlined workflow gets it done in 24-48 hours. That's not just faster—it's the difference between your team staying on top of finances and constantly playing catch-up.

Step 1: Map Your Current Process (Yes, Really)
Before you build anything, you need to understand what you're actually doing now. Most teams haven't written down their approval chain. It lives in someone's head or in a series of email rules.
Sit down with whoever manages expenses today. Ask these specific questions:
- Who submits expenses?
- Who approves the first level?
- Who approves the second level (if there is one)?
- What triggers a rejection?
- How long does each step usually take?
You'll probably find that approval time isn't actually spent reviewing—it's spent waiting. Someone's on vacation. Someone didn't see the email. The system doesn't send reminders. That's where your automation wins. You're not replacing judgment. You're eliminating delays.
Step 2: Set Up Automated Routing
This is where the workflow actually does work for you. Instead of manually forwarding expenses to different people, you create rules that route automatically.
Most low-code platforms let you create conditional routing. Here's a practical example:
- Expenses under $500 Direct manager approval only
- $500-$2000 Manager + Finance team lead
- Over $2000 Manager + Finance lead + Director
The workflow doesn't ask you to choose. It looks at the amount and routes it automatically. No decisions, no delays, no "oops, I forgot to send this to the director."

Step 3: Add Approval Notifications
Here's where speed really happens. Your workflow needs to notify approvers immediately when something lands in their queue. Not a weekly digest. Not a daily summary. Right away.
Most low-code tools send email notifications automatically. That's fine for a start. But you can do better. Set it up so that:
- Notifications include the expense amount and category (so approvers can make quick decisions)
- Direct links go straight to the approval screen (no hunting through menus)
- A reminder goes out after 48 hours if something's still pending
You're not bugging people. You're removing friction. When an approver sees a notification with all the info they need and a direct link, they're more likely to handle it immediately rather than putting it off.
Step 4: Create Visibility for Everyone
One more thing that kills approval cycles: people don't know where their expense is in the queue. Did it go through? Is someone reviewing it? Is it stuck?
Your workflow should give employees a simple dashboard where they can see:
- All submitted expenses and their status
- Who's currently reviewing
- Expected approval date
This reduces "where's my reimbursement" emails by about 70%. Employees see the status in real time. You're not hiding the process—you're showing it. That builds confidence and reduces follow-up work.
The Real Win: Time and Clarity
You've now got a workflow that routes automatically, notifies people immediately, and keeps everyone in the loop. That's it. That's the setup that cuts approval cycles in half.
The numbers speak for themselves. If you're currently processing 50 expenses per month and each one takes 8 days on average, you're managing 400 "expense-days" of work. Cut that to 2 days per expense and you're down to 100 expense-days. Your team has time for actual finance work instead of chasing approvals.
And here's the thing—this isn't theoretical. Teams we've worked with have implemented this exact process. The ones who stuck with it saw results in the first month. Not "eventually." Not "if you're lucky." In the first month.
Start with mapping your current process. Build the routing. Add notifications. Create visibility. You don't need to be perfect. You need to be faster than you are today. And this approach gets you there.
