Approval workflow software

Approval workflow software for any approval, however complex

What does approval workflow software do?

It routes requests for review, sign-off and record-keeping — automatically. With Zenphi, approvals run in Google Workspace or Microsoft 365: requests start from forms, email or chat, approvers are found in Google Directory or Microsoft Entra ID, and decisions take one click from email, Google Chat or Microsoft Teams.

Definition

What is approval workflow software?

Approval workflow software routes a request to the right people for review and sign-off, then records the outcome. It replaces manual email chasing with defined steps, conditions, and an audit trail. Requests move automatically from one approver to the next until a decision is made.

How it works

How approval routing works

Approval routing is the logic that sends each request to the right people, in the right order, under the right conditions. Approval routing software lets you set that logic once and then runs it automatically. Three patterns cover most approvals, and real processes combine them.

Sequential routing

Approvers act one after another. Each person sees the request after the previous approver signs off. This fits sign-offs that must happen in a set order, such as manager, then finance.

Parallel routing

Several approvers act at the same time, and the request advances once the required approvals are in. This is faster when multiple departments weigh in independently.

Conditional routing

The path changes with the request. Rules branch by amount, type, or department, so a small purchase and a large one follow different approval chains.

Completion rules

Decide when a step is complete — and combine rules across stages.

  • First to respond

    The request moves on as soon as any one approver decides.

  • Everyone must approve

    The request waits until every approver has signed off.

  • A specific person

    The request waits for one named approver — say, the CFO — whatever the others decide.

Approval thresholds set the point where a request needs higher sign-off — for example, anything above a set amount escalates to a director. Delegation keeps work moving when an approver is away, reassigning the decision to a deputy so nothing stalls. Together, these turn a written policy into an automated approval workflow that runs the same way every time.

Why Zenphi is different

How Zenphi handles any approval process, without per-user pricing

However complex the approval and however many people take part, Zenphi adapts the workflow to your process.

Zenphi doesn’t charge per user or per execution

Add every employee as a requester or approver and run as many requests as you need. Zenphi is priced per process, so your bill doesn’t grow with headcount or volume.

ZAIA, Zenphi’s AI copilot, builds it for you

ZAIA is the AI assistant inside Zenphi that turns a plain-English description into a working approval workflow — plus the forms and tables it needs — in minutes.

Every step in Zenphi is customisable

In Zenphi’s no-code designer you can change any step, condition, message or document, however complex the approval — starting from a template or from scratch.

Zenphi supports every routing pattern

Sequential, parallel, conditional and multi-step approvals run in one Zenphi workflow, with reminders, expiry dates, escalation and delegation built in.

Zenphi finds the right approver automatically

Zenphi’s integration with Google Admin and Microsoft Entra ID looks up the manager, department head or any role when the request arrives — even after a reorganisation.

Zenphi lets you set any completion rule

Wait for the first approver, wait for everyone, or wait for one specific person before Zenphi moves the request forward.

What matters

6 features to look for in approval automation software

The crucial aspects of every approval workflow automation platform, and how Zenphi helps with each, as you compare workflow approval software.

Flexible routing and custom loops

Real approvals branch, stack, and repeat. A rigid, template-only tool forces workarounds or breaks the moment your process does not fit its mold.

Make sure the solution you’re choosing supports sequential, parallel, and conditional routing, plus custom approval loops you can shape to your exact process.

How Zenphi helps: build custom approval loops with or without templates, no code, from a single sign-off to a multi-stage chain.

Control of the asset under approval

A common failure is someone editing the document mid-review, so the version that gets approved is not the version that was checked.

Make sure the solution you’re choosing supports locking the asset under review, so it can’t be changed while the approval is in progress.

How Zenphi helps: Zenphi can lock the asset — a contract in Google Drive, OneDrive or SharePoint, for example — during the approval, so what’s approved is exactly what was reviewed.

Handling an unavailable approver

Approvals stall when one person is on leave or slow to respond, and requests sit forgotten in an inbox while the process waits.

Make sure the solution you’re choosing supports reminders, escalation after a deadline, and delegation to a deputy.

How Zenphi helps: set reminders, expiry dates, and escalation, and reassign the decision automatically so a single absence doesn’t stall the workflow.

A complete audit trail

Without a record of who approved what and when, audits and compliance reviews turn into a scramble, and disputes are hard to settle.

Make sure the solution you’re choosing supports logging every step, with approver, timestamp, and context, and clear status visibility.

How Zenphi helps: every step is logged with approver, timestamp, and context, and status dashboards show where each request stands.

Approvals where work already happens

A separate approval portal means another login and another tool to learn, so adoption drags and approvals get skipped.

Make sure the solution you’re choosing supports decisions inside the tools people already use, rather than a standalone portal.

How Zenphi helps: approvers decide in one click from email, or in Google Chat or Microsoft Teams, and requests start from forms, document folders, email or chat — with no separate system to adopt.

An AI assistant to build workflows

Building and changing workflows by hand is slow, and it often falls to one technical person, creating a bottleneck every time something needs to change.

Make sure the solution you’re choosing supports a fast way to build workflows, ideally an assistant that drafts one for you from a description.

How Zenphi helps: ZAIA, Zenphi’s automation copilot, creates an approval workflow from a plain-language prompt, and you can add AI steps with Gemini, OpenAI, Claude or your own models where judgment is needed.

Zenphi AI Studio

Approvals in a conversation, with an approval agent

Zenphi’s AI Studio deploys your approval workflows into conversational interfaces. Employees ask in plain language; the agent checks the rules, routes the request to the right approver and confirms the outcome.

  • Deploys where people already askGoogle Chat, Microsoft Teams or Zenphi Assistant — typically in about 30 minutes.
  • Approvers decide in the conversationOne click on the approval card, with the request details and context attached.
  • Bound to your workflowsThe agent understands intent; every action it takes is a step you defined. Every conversation and decision is logged.

FAQ

Approval workflows — frequently asked questions

Choosing a tool
Which tools are best for managing approval workflows?

The right tool depends on your ecosystem and how complex your approvals are. Options include general automation platforms, enterprise workflow suites such as Kissflow, and tools built into one ecosystem, such as Microsoft Power Automate. Match the tool to your environment, your routing complexity, who will maintain the workflows, and how pricing grows with users and volume.

Zenphi focuses on no-code approval automation with flexible routing, audit trails and low maintenance, in Google Workspace or Microsoft 365, with no per-user or per-execution fees.

What are recommended tools for automating approval processes?

Microsoft-centric teams often start with Power Automate, broad multi-app teams use general integration platforms, and some organisations choose a dedicated workflow suite such as Kissflow. Whichever you consider, look for flexible routing, an audit trail, approvals where people already work, and low administrative overhead.

Zenphi runs approvals natively in Google Workspace and Microsoft 365 — Docs, Forms and Drive, or Word, SharePoint and OneDrive — with no code.

How does Zenphi compare with Kissflow for approval workflows?

Kissflow is a dedicated workflow platform where approvals run in the Kissflow app, priced as a platform fee with a user cap on an annual commitment. It suits organisations that want a standalone process portal.

Zenphi runs approvals where people already work — email, Google Chat or Microsoft Teams — finds approvers live in Google Directory or Microsoft Entra ID, and charges per process with no per-user fees. ZAIA can import existing Kissflow approval workflows.

What are the key features to look for in approval management software?

Look for flexible routing (sequential, parallel and conditional), handling for an unavailable approver, control of the asset under review, a complete audit trail, approvals in the tools people already use, and low maintenance. An AI assistant that builds workflows from a prompt is a plus. Approval management software that covers these will hold up as your processes grow.

Zenphi is built around exactly these features, with ZAIA to build and change workflows from a description.

Improving approvals
How can I streamline the approval process in my organization?

Start by mapping each approval: who requests, who approves, in what order, and what happens on delay. Then remove the manual steps — route requests automatically, set reminders and deadlines, and record every decision.

Zenphi automates the routing, reminders and record-keeping end to end, so approvals stop waiting in inboxes.

How does automation improve the approval process?

Automation removes the waiting and the chasing. Requests route to the right approver instantly, reminders and escalations prevent stalls, and every action is logged for compliance. The result is faster decisions, fewer errors, and a complete audit trail.

Zenphi adds this with no code, in Google Workspace or Microsoft 365.

What are the ways to improve the approval process?

Common improvements include standardising the steps, routing by clear rules, adding reminders and escalation for delays, enabling delegation when an approver is away, and keeping an audit trail. Locking the document under review prevents mid-approval edits.

Zenphi brings these together in one no-code workflow.

How can I improve my approval workflow to make it more efficient?

Cut the manual handoffs. Trigger the workflow automatically, branch by amount or type so simple requests move faster, set expiry dates and escalation, and give approvers a one-click decision. Keeping the record automatic means no one reconciles spreadsheets later.

Zenphi automates approvals without anyone leaving the tools they use — Google Docs, Forms and Drive, or Word, SharePoint and OneDrive.

Your environment
Can I customize approval processes in Google Workspace?

Yes. Approvals can be tailored to your rules — custom routing, conditions, thresholds, reminders and escalation, with approvers found in Google Directory.

For approvals across Google Docs, Google Forms and Drive, Zenphi lets you build custom approval loops with or without templates, no code, so the process matches how your organisation actually works.

Can I customize approval processes in Microsoft 365?

Yes. Approvals can follow your own routing, conditions, thresholds and escalation, with approvers found in Microsoft Entra ID, requests starting from SharePoint or forms, and decisions made in Outlook or Microsoft Teams.

Zenphi builds custom approval loops across Word, SharePoint, OneDrive, Outlook and Teams with no code, with no per-user or per-execution fees.

Can I migrate approval workflows from Power Automate or Kissflow?

Yes. Export the existing workflow, upload the file and connect your environment. The approval steps, conditions and notifications are mapped to their equivalents, ready for you to review and test.

In Zenphi, ZAIA imports exported Power Automate and Kissflow approval workflows in minutes, for Google Workspace or Microsoft 365.

Can employees request and approve inside Google Chat or Microsoft Teams?

Yes. A conversational agent can take a request in plain language, check the rules, send it to the right approver and confirm the outcome — with approvers deciding on a card in the same conversation.

Zenphi’s AI Studio deploys approval workflows to Google Chat, Microsoft Teams or Zenphi Assistant, and every action the agent takes is a workflow step you defined.

How does automatic approval work in HR systems?

Automatic approval routes a request — a leave request, expense, or new-hire action — to the right manager based on rules like department or seniority, applies policy checks, and approves or escalates without manual steps.

Zenphi handles this end to end — from a form, email or chat request through the decision to follow-ups such as an out-of-office reply on approved leave.
