A plant supervisor flags a critical spare part shortage at 9 AM Eastern. The requisition gets typed into a spreadsheet, emailed to a manager, forwarded to finance, sent back for a missing budget line, and finally signed off three days later. The vendor takes another four working days to ship. The line sits idle. Anyone who has run procurement inside a manufacturing business has seen some version of this script.
Manual purchase requisition approvals were never built for a factory floor that runs on tight margins, leaner inventories, and shorter delivery windows. That is the precise reason a growing number of manufacturers running Microsoft Dynamics 365 Business Central are moving requisition handling into a dedicated app inside their ERP. Here is what is changing, and what to look for before picking one.
The cost of manual approvals in a manufacturing setting
Email threads, paper forms, and side spreadsheets feel cheap because no one is invoicing for them. The real cost is the operational friction that builds up underneath, and in a manufacturing business, that friction shows up in three specific ways.
Production stoppages from approval lag
A maintenance part that needs same-day ordering sits in someone’s inbox while the team tracks down the approver on a plant tour. Multiply that across hundreds of small purchases a month, and uptime quietly takes a hit.
Maverick claims that the audits cannot trace
When approvals are routed informally, buyers raise POs without budget checks, vendors slip in without due diligence, and finance only catches the variance at month-end close. Compliance suffers, and so does the relationship with internal auditors.
Procurement teams are stuck on coordination work
Senior procurement staff who should be negotiating commercial terms end up chasing signatures. The capability is misused, and the supplier base never gets the attention it needs.
What a business central purchase requisition app does
A purchase requisition app for Dynamics 365 Business Central is an extension that runs inside the same ERP environment. The app captures requests in a structured format, routes them through configurable approval rules, validates against budget and inventory, and converts approved requests into purchase orders without rekeying anything.
All requests in one place
Anyone with access can raise a request. Items, fixed assets, services, and general ledger lines are all supported, with required fields enforced at entry.
Approval workflows that hold
Multi-level approvals are tied to spend thresholds, cost centers, project codes, and categories. The system enforces the chain rather than relying on memory.
Direct line into business central data
Approved requisitions become purchase orders automatically. Vendor records, item masters, and the chart of accounts stay consistent because the app shares the same data model.
The purchase requisition app for Dynamics 365 Business Central from Advaiya follows this pattern, using a peripheral automation approach that extends Business Central without modifying the core ERP.
What a Dynamics 365 purchase requisition workflow looks like once automated
Most manufacturers settle on the following sequence after a clean implementation.
- A requester raises a requisition inside Business Central with item, quantity, expected date, and cost center.
- The app validates inventory, budget, and standard pricing in real time.
- Approval routes are triggered based on amount, category, or department.
- Approvers receive a notification and act from a mobile view or Outlook.
- Approved requisitions convert to purchase orders, optionally through an RFQ step.
- The PO flows through receiving, three-way match, and payment with full audit history.
For teams that want a vendor comparison layer, an RFQ and quote comparer extends this same flow with structured supplier responses.
What to look for in purchase order approval software for manufacturing
Not every app on Microsoft AppSource handles the demands of a manufacturing procurement function. A few capabilities separate the serviceable ones from the genuinely useful ones.
Budget and inventory checks at the point of request
The app should validate against open budget and current stock before the approval starts, not after. Catching a missing budget allocation at the requestor stage saves three downstream emails.
Configurable, multi-level approvals
Approval chains should be tied to category, value, and project. Hard limits, soft warnings, and delegation during leave should all be available.
Integration with the wider procurement stack
Look at how the app handles RFQs, vendor comparisons, and short-close scenarios. A connected flow into the rest of the business process automation stack keeps the whole chain auditable.
Audit trail and reporting
Every approval, edit, and rejection should be timestamped and queryable, with procurement reports running inside Business Central rather than from Excel exports.
A partner with manufacturing implementation experience
The configuration choices matter more than the feature list. Pick a partner who has implemented this in a similar industry, not just demoed it.
An executive read on why this shift is happening now
The move away from manual approvals is not about saving time on signatures. Procurement is being asked to earn a seat at the planning table, and that is hard while the function is buried in routing work. According to Deloitte’s 2025 Global Chief Procurement Officer Survey, the most digitally mature procurement organizations now direct as much as 24% of their budgets to procurement technology, with a strong tilt toward AI.
For a manufacturing CFO, the question is no longer whether to automate requisitions. The deeper question is whether the existing investment in enterprise resource planning is delivering the operational discipline it was supposed to. A requisition app sitting inside Business Central is one of the cleanest, lowest-risk ways to close that gap, especially for manufacturers who want to keep the core ERP untouched while adding the workflow rigor their procurement teams need. Done well, it pays back in weeks, not years.
Ready to put procurement on a working footing?
If purchase approvals still live in inboxes, the cost is showing up somewhere, usually as production delays, audit findings, or supplier frustration. Before another quarter passes, a focused conversation about your procurement flow can surface the right next step, whether that is a requisition app, a wider business process automation review, or a full manufacturing digital transformation roadmap.

Frequently asked questions
A purchase requisition is an internal request to buy something. Within Dynamics 365 Business Central, the requisition is the structured input that precedes a purchase order, with details on item, quantity, budget code, and approver routing.
The standard product includes a requisition worksheet meant for planning and replenishment. Most manufacturers extend it with a dedicated purchase requisition app for multi-level approvals, validation, and audit trails.
A typical configuration takes four to eight weeks, depending on approval complexity, the number of cost centers, and integrations with other systems.
Most purchase requisition apps support general ledger postings, fixed-asset requests, and service requisitions in the same flow as item-based requests.
The app validates the requested amount against the open budget at the point of request and again at approval, with optional warnings and hard stops. Finance sees the commitment before the PO is raised, not after.
The benefits scale down well. Smaller manufacturers need fewer approval levels, but the audit trail, budget control, and direct connection to inventory and finance data inside Business Central still pay for themselves.
