An approval process and workflow is an automated sequence of steps that routes a request — document, budget, purchase order, or leave request — through defined approvers in a specific order, enforcing rules and capturing decisions at each stage without manual follow-up. It is the operational backbone of governed enterprise operations.
Every business runs on approvals. Marketing cannot publish content without sign-off. Finance cannot release payments without authorisation. HR cannot hire without headcount approval. IT cannot deploy without change management sign-off. These approvals are not bureaucracy — they are governance. The problem is not the approval itself. It is the manual process around the approval.
An email approval system is a liability masquerading as a process. Requests get buried. Approvers forget. Decisions are made without full context. Nobody knows where a request stands. Audit trails do not exist. Compliance cannot be demonstrated. Every manual approval is a potential bottleneck, an error risk, and a governance gap.
This guide covers what approval workflows are, how they work, the 8 most important types, how to design them, and how to automate them using a no-code platform — with no development resource required.

What is an Approval Process?
An approval workflow is a defined sequence of review and decision steps that a request, document, or transaction must pass through before it is authorised. At each step, a designated approver — or group of approvers — reviews the submitted information and either approves it (moving it to the next step), rejects it (returning it to the requester with feedback), or escalates it (routing it to a higher authority).
Employees spend nearly 20% of their time searching for information or tracking down approvals.
In a properly designed approval workflow, every step has a defined owner, a defined time limit, a defined escalation path, and a complete audit record of the decision made.
| Element | What It Means |
| Trigger | The event that starts the approval — form submission, request creation, threshold breach |
| Requester | The person or system initiating the approval request |
| Approver(s) | The defined person(s) who must review and decide at each step |
| Approval conditions | The rules that determine routing — amount threshold, department, request type, data value |
| SLA | The time limit within which each approver must act before escalation fires |
| Escalation | The automatic action taken when SLA is breached — notify manager, re-route, flag as overdue |
| Audit trail | The immutable log of every decision, timestamp, and approver identity throughout the workflow |
| Outcome | Approved (next step or process trigger), Rejected (return with feedback), or Escalated (route up hierarchy) |
5 Steps of an Approval Process
Step 1 — Submission
The requester submits the request — with all required information, supporting documents, and context — through a defined channel. In a manual process, this is typically an email or a printed form. In an automated workflow, it is a structured digital form that validates required fields, enforces formatting rules, and captures all data in a consistent, accessible format before routing begins.
Step 2 — Initial Review
The first designated approver receives the request and reviews it against defined criteria. This may be a direct manager, a department head, a compliance officer, or an automated validation check for certain conditions. The approver has three options: approve and route to the next step, reject and return with feedback, or request additional information before deciding.
Step 3 — Multi-Level Review (where applicable)
Complex or high-value requests route through multiple review stages — each with different approvers and different criteria. A purchase order under £5,000 may require one approval. Over £50,000, it requires three. Each level enforces its own governance requirements. Parallel approvals allow multiple reviewers to assess simultaneously when their decisions are independent.
Step 4 — Final Authorisation
The final approver — typically the most senior stakeholder in the chain — provides the authoritative decision. In regulated processes, this step may have legal significance: the final approver’s identity, timestamp, and decision are recorded as the authoritative record. Automated workflows capture all of this automatically.
Step 5 — Execution and Notification
Once final approval is granted, the outcome triggers the next action automatically: payment processing, contract execution, publication, access provisioning, or whatever the approved request requires. All stakeholders — requester, approvers, and affected parties — are notified simultaneously. The complete approval chain is archived as the audit record.

8 Types of Approval Workflows — With Examples
1. Purchase Order Approval
A purchase request submitted by any employee triggers a routing workflow based on value: under £5,000 routes to team lead, over £5,000 to department head, over £50,000 to finance director. Each approver receives full context — vendor, line items, cost code, business justification, and prior approvals. Approved POs trigger vendor notification automatically.
2. Leave and Absence Approval
Employee submits a leave request specifying dates, type (annual, sick, compassionate), and cover arrangements. System routes to line manager. If manager approves, HR is notified automatically and the leave balance updated. Payroll integration ensures approved leave is reflected in the next pay run without manual entry.
3. Content and Marketing Approval
Content briefs, creative assets, campaigns, and press releases route through editorial, legal, compliance, and brand sign-off in sequence. Each stage has a defined SLA — legal review must complete within 48 hours. Escalation fires if any stage exceeds its SLA. Published content can only go live after every required approval is captured.
4. Budget and Expenditure Approval
Budget requests, project cost increases, and unplanned expenditure route through finance based on amount and cost centre. Each approver sees the full budget picture — original allocation, prior spend, and the impact of the current request. Approved requests trigger real-time budget dashboard updates.
5. HR and Recruitment Approval
Hiring requests route through department head, HR business partner, and finance for headcount and budget confirmation before recruitment begins. Offer letters route through HR and legal before issue. Compensation exceptions route to compensation committee. Each step is documented for regulatory compliance.
6. IT Change Management Approval
IT change requests — system updates, configuration changes, access provisioning — route through technical review, security assessment, and change advisory board sign-off. High-risk changes require additional approval stages. Emergency changes have an expedited but still documented approval path.
7. Contract and Legal Approval
Contracts route through commercial, legal, risk, and executive sign-off based on value and risk profile. Each approver reviews specific aspects — commercial terms, legal compliance, risk exposure, financial commitment. Final execution requires digital signature from authorised signatories. The complete chain is the contract audit trail.
8. Vendor Onboarding Approval
New vendor requests route through procurement, legal, finance, and information security in sequence. Compliance documentation collected automatically from vendor at submission. Each approver validates their specific requirements — commercial terms, legal standing, financial stability, data security standards. Approved vendors activated in systems automatically.

Manual vs Automated Approval Workflows: The Real Difference
| Problem with Manual Approvals | How Automation Resolves It |
| Requests buried in email inboxes | Every request in a central, trackable system with full history and status visibility |
| No visibility into where a request stands | Real-time status dashboard — requester, approvers, and stakeholders see current position instantly |
| Approvers forget or delay without reminders | Automated SLA timers and reminder notifications. Escalation fires without any human intervention. |
| Different approvers apply different criteria | Approval conditions enforced automatically — same rules applied consistently every time |
| No audit trail for compliance | Every action logged with timestamp, user identity, and decision data — immutable and audit-ready |
| Version confusion on documents | Single version of record attached to the workflow instance — no email attachment chaos |
| High-value requests not getting appropriate oversight | Threshold-based routing ensures requests above defined values automatically escalate to senior approvers |
| Approval chains break down on holiday coverage | Delegation rules configured in advance. System routes to designated delegate automatically. |
How to Build an Automated Approval Workflow in Quixy
| Step | Action | What to Do |
|---|---|---|
| Step 1 | Define your approval logic | Map the process: identify requester, approvers at each level, routing conditions, SLAs, and outcomes. Define thresholds, exceptions, and delegation rules clearly. |
| Step 2 | Build the submission form | Use a drag-and-drop form builder to create the request interface. Configure required fields, validation rules, document uploads, and conditional fields based on inputs. |
| Step 3 | Configure the approval chain | Set up each approval step in the workflow builder. Assign approvers (role-based, individual, or dynamic), define routing logic, and configure SLA timers and escalation paths. |
| Step 4 | Set notifications and escalations | Automate alerts for key events—submission, approval, rejection, SLA breaches. Configure channels like email, SMS, WhatsApp, or in-app with relevant context. |
| Step 5 | Test and deploy | Test workflows in a sandbox with real scenarios and edge cases. Validate rejection paths, delegation, and escalations. Deploy once ready and monitor via dashboards. |

Frequently Asked Questions(FAQs)
Q. What is an approval process in business?
An approval process is a formal business procedure that routes a request — a document, budget, purchase order, or leave application — through a defined sequence of decision-makers, each of whom must review and either approve, reject, or escalate before the process moves forward. The purpose is to ensure that decisions are made by the right people, with the right information, in the right order — and that every decision is documented.
Q. What is the difference between an approval process and an approval workflow?
An approval process is the policy — the organisational rules about who must approve what and under what conditions. An approval workflow is the implementation of that policy as a structured, executable sequence of steps, either manual or automated. In practice the terms are often used interchangeably, but strictly: the process defines the rules, the workflow executes them.
Q. How do you automate an approval workflow without coding?
No-code aPaaS platforms provide visual workflow builders where approval chains are configured by dragging and connecting steps, setting conditions, and specifying approvers — without writing a single line of code. The form that captures the request is built using a drag-and-drop form builder. Routing rules, SLA timers, escalation paths, and notification messages are all configured through graphical interfaces. A first approval workflow is typically live within one to two days.
Q. What are the most common approval workflow mistakes?
The five most common approval workflow failures are: unclear ownership at each step (who specifically approves, not just which department), missing SLA enforcement (no consequence for delayed approvals), no delegation rules for absence cover, no escalation path for exceptions, and no audit trail. Automated approval workflows eliminate all five by enforcing ownership, SLAs, delegation, escalation, and logging as built-in system behaviours.
Q. How does approval workflow automation support compliance?
Automated approval workflows create an immutable audit trail — every request, approval, rejection, and decision is logged with the approver’s identity, timestamp, the data they reviewed, and the outcome. This satisfies compliance requirements for SOX, ISO 27001, GDPR, and industry-specific regulations without any manual record-keeping. When an auditor requires evidence that a payment was properly authorised, or that a high-risk change went through the correct review stages, the complete chain is available instantly.
