Approval Workflow Software
Approval workflows route decisions to the right person at the right time, track their status, enforce deadlines, and escalate when approvals stall. When approvals happen over email, the status is invisible to anyone not on the thread, the requester doesn't know if the approval is pending, rejected, or simply forgotten. Finance doesn't know which invoices are waiting. Procurement doesn't know which purchase orders are approved.
RaftLabs builds approval workflow software with configurable routing rules, approval tiers, SLA monitoring, escalation logic, and a status view that shows where every item in the workflow currently sits. For invoice approval, purchase order sign-off, contract review, expense authorisation, HR requests, and any other process that requires a documented decision trail.
Configurable approval routing, by value, by department, by vendor, or by any business rule your process requires
SLA monitoring with automatic escalation when an approval hasn't moved within the configured time limit
Full audit trail for every approval decision, who approved, when, and any comments recorded at the time
Requestor-facing status view showing where their item is in the approval chain without emailing the approver

The problem
When a purchase order or invoice is stuck waiting for approval, how does the requester find out its status, and how does the approver's manager know that approvals are stalling?
When your auditors ask for a record of who approved which invoices in Q3, how long does it take to produce that evidence, and how complete is it?
Short answer
RaftLabs builds approval workflow software that routes invoice, purchase order, contract, expense, and HR sign-offs to the right approver, enforces SLA timers, escalates stalled items, and records an immutable audit trail. Threshold-based routing sends each request to different approvers by amount, department, or risk. A first workflow for one process type launches in roughly 6 to 8 weeks, then expands.
Key takeaways
Trusted by
Approval workflows break down when the process lives in email. Someone sends a request, the approver gets a message, that message sits unread or gets buried, and the SLA expires without anyone noticing. Finance cannot see which invoices are awaiting sign-off. Procurement cannot see which purchase orders are stuck. Six months later, an auditor asks for the record and gets a spreadsheet that may or may not reflect what happened.
A broken approval process costs you delayed payments, missed procurement deadlines, compliance gaps, and the hours managers burn chasing decisions that should have routed, tracked, and escalated themselves. Approval workflow software replaces the email chain with a structured process that routes each request, tracks its status, escalates when it stalls, and records every decision from submission to sign-off.
According to McKinsey's 2024 State of AI report, 66% of organizations have now automated at least one business function, up from 57% a year earlier. In finance and operations, approvals are usually the first bottleneck teams hit: the step that still waits on a person, an inbox, and a reminder.

Capabilities
Routing rules are defined as condition-action pairs an administrator can configure without code changes, so the approval chain adapts to each request by value threshold, vendor type, department, or risk category. Each step runs sequential, parallel, or any-one approval, and every routing decision is deterministic and logged so it's explainable to auditors.
SLA thresholds are configured per approval step and urgency level, with business-hours-only calculation so weekends and holidays don't consume the window. Approvers get a reminder at 70% of the SLA, breaches notify their manager or auto-assign to a delegate, and reporting on cycle time and breach trends shows whether slow approvals are a process, capacity, or approver problem.
The audit trail is an append-only log where every submission, approval action, routing decision, escalation, reassignment, and attachment is a new record that cannot be modified or deleted, with per-event hashing making it tamper-evident. Exports produce a structured evidence pack filtered by date, type, or approver, and records are retained in immutable cold storage for a configurable period. The record set is built for SOX segregation-of-duties reviews and SOC 2 evidence requests, so a finance auditor gets the full chain of who approved what and when, without a manual reconstruction.
Each role gets a tailored dashboard on the same data model. Requestors see where every submission sits against its SLA. Approvers see their queue sorted by urgency, with direct approve and reject. Managers see cycle times, breach rates, and overdue items, with bulk reassignment. Notifications go out on each user's preferred channel.
Rejection is structured to speed resolution rather than terminate the request: approvers must select a reason code, so requestors never receive an uninformative "rejected" with no context. Revisions resubmit against the original with version history and a diff view of exactly what changed, and line-item requests support partial approval so approved lines advance while rejected lines get targeted notifications.
Integration with the system where each approval item originates, so requests are created automatically and decisions update the source record without manual status changes. Connectors cover major ERP, procurement, expense, and HR platforms, approvers view the actual contract or invoice PDF inside the interface, and SAML 2.0 SSO with SCIM provisioning keeps authentication corporate.

Supply Chain Automation with AI: The Practical Guide for Operations Leaders
Supply chains lose 4-8% of revenue to inefficiency every year. Demand mismatch, late POs, manual receiving, and slow supplier onboarding. AI automation closes most of these gaps. Here is the playbook, workflow by workflow.
Read moreYes. Threshold-based routing is a standard approval workflow pattern: a purchase order under $5,000 routes to the department manager, $5,000 to $25,000 routes to the department manager and finance director, above $25,000 routes to the CFO. Risk-based routing works the same way with risk score as the routing attribute. Routing rules are configured during setup and can be modified by an administrator without code changes. Multiple routing attributes can be combined, amount AND vendor type AND department all influencing the approval chain.
Absence handling is configured per approver: a delegate approver for planned absence (holiday, parental leave) who receives approval tasks during the absence period, or automatic escalation to the approver's manager when an SLA expires without action. Delegates are configured in the system by the approver before their absence. For unexpected absence, the SLA escalation path handles the routing automatically without manual intervention. The audit trail records that the delegate or escalation approver acted on behalf of the original approver.
A first workflow covering a single approval type (invoice approval or purchase order sign-off) with configurable routing, SLA monitoring, and audit trail launches in roughly 6 to 8 weeks, then expands as you add approval types. A more complete system covering multiple approval types, complex routing logic, integration with ERP or procurement systems, and a manager analytics dashboard takes 10 to 16 weeks. Fixed cost agreed in writing before development starts.
Yes. Integration with the source system (the ERP that generates invoices, the procurement system that creates purchase orders, the HR system that initiates employee change requests) means approval items are created automatically from the source system rather than entered separately. Approval decisions are pushed back to the source system to update the record status. The integration scope depends on what APIs your source systems expose and is assessed during the project scoping.
