ERP for Approval Workflows

Symptoms: when approvals are slowing you down or not controlling anything

Approval problems come in two opposite forms, and many businesses have both at once. The signs that you need a proper ERP approval workflow include:

• No record of who approved what. Approvals live in email and chat, and audits mean searching inboxes.
• Requests wait days for one person. A director is traveling, and purchases, payments or discounts stop.
• Too many approvals for small things. Routine requests go through several levels, so people split orders or skip the process.
• Approvals happen after the fact. Goods are ordered, discounts given or payments made, then approval is requested to tidy up the paperwork.
• Different rules in different places. One department needs approval above a certain value, another never asks.
• Nobody can see what is pending. Requesters chase approvers by phone because the system shows nothing.
• Audit findings repeat. The same control weaknesses are reported every year.

These patterns are common across construction, healthcare, real estate and any business where many people commit spend or make customer-facing decisions on the company's behalf.

Root-cause checklist

Before configuring any workflow, I check the foundations:

• Is there a written delegation of authority? Without one, the workflow has no rules to follow.
• Is the policy proportionate to risk? Heavy approval for low-value, routine spend creates workarounds.
• Is the approval point in the right place? Approving an invoice after goods are received controls less than approving the request before the order.
• Are roles defined independently of people? Workflows tied to named individuals break when someone leaves or changes role.
• Is there cover for absence? Without delegation rules, approvals stop when people are away.
• Do approvers have the context to decide? If they must open three systems to understand a request, they delay it.
• Does the system support the routing you need? Some tools handle only one approval level or one condition.

Most of these are governance questions for management and finance. I work through them using process mapping of each approval flow, which often shows that several approvals can be removed and one or two important ones moved earlier in the process.

Solution options

Fixing approvals can involve policy, configuration or new tools:

Approvals usually sit inside bigger processes. Purchase approvals are part of procurement automation, invoice and payment approvals part of finance automation. Designing the approval in context avoids building a control that sits in the wrong place. Where approvals connect to other automations, such as notifications or document capture, I plan them as part of business automation, and record the rules in the ERP solution design.

Platform fit for approval workflows

Approval capabilities differ between platforms mainly in routing flexibility, the documents they can apply to and how approvals are given:

• Odoo offers approval thresholds on purchases and other documents, an approvals app for general requests and configurable rules, with deeper routing possible through customization.
• ERPNext has a configurable workflow engine that can apply states, roles and conditions to most document types, which suits businesses with varied approval needs.
• Dynamics 365 Business Central includes approval workflows for purchases, sales, payments and master data, and can be extended with Microsoft's broader workflow tools.
• Zoho Books supports approvals on transactions for smaller teams, and Zoho Creator can model multi-level, cross-app approval flows where standard settings are not enough.

For any platform, I test with your real approval matrix: a routine request under the threshold, a high-value request needing several levels, a request while the approver is away, and a rejection with resubmission. Those four scenarios reveal most limitations quickly, before you commit to a design.

Cost drivers and a phased timeline

The effort behind an ERP approval workflow depends on:

• Number of documents under approval. Purchases only is simpler than purchases, invoices, payments, discounts, expenses and master data changes.
• Routing complexity. Rules by amount alone are simple; rules by amount, entity, project, category and customer need careful design and testing.
• Cross-system approvals. Approvals that touch several systems need integration or a separate workflow layer.
• Delegation and escalation rules, including holiday cover and reminders.
• Mobile and email approval requirements.
• Change management. New controls change habits, especially for senior people used to approving informally.

The timeline usually moves in phases. First, inventory all approvals in use, formal and informal. Second, agree a proportionate delegation of authority with management and finance. Third, configure the highest-value workflows first, usually purchases and payments, and test with real scenarios. Fourth, pilot with one department and review approval times and bottlenecks. Finally, extend to other documents and tune thresholds once real volumes are visible. Starting with too many workflows at once is the most common reason approval projects stall.

Next steps

Good approval workflows start with an honest look at how decisions are actually approved today, including the informal routes that bypass policy. Those routes usually exist for a reason, and the new design has to address it.

To start, I usually ask for:

• Your current delegation of authority or approval policy, if one exists
• A list of documents that need approval, formally or in practice
• Recent examples of approvals that were slow, skipped or disputed
• Any audit findings related to approvals or controls

From that, I recommend a proportionate approval matrix, which workflows to automate first and whether your current system can support them. If new tooling is needed, the approval scenarios become part of your requirements and every vendor demo.

As an independent consultant, I am not selling a workflow tool, so I can recommend fewer approvals where that is the right answer. Business first, technology second. Contact me to review your approval workflows.
