Purchase Requisition Approval Routing
Approving a purchase requisition should involve knowing whether the department actually has budget remaining for that spend category, but approvers routinely make this call without real visibility into current budget position — checking a spreadsheet that's weeks out of date, or simply trusting that if the requester submitted it, it's probably fine. This means departments can and do overspend their budget through a series of individually-approved requisitions that nobody connected to the cumulative total, and this usually only surfaces as a problem at month-end when actuals come in over budget and nobody can point to the specific decision that caused it.

How the automation works
We connect requisition routing directly to live budget data, so every requisition presented to an approver shows real-time remaining budget for that cost centre and category, not a stale reference number — making the approval decision genuinely informed rather than a formality. Requisitions that would push a department over its remaining budget are flagged explicitly rather than silently approved, giving the approver a clear choice to approve with awareness of the overage, redirect the requester, or decline, instead of finding out at month-end that a string of individually reasonable approvals added up to a real problem.
Process flow
- 01
Requisition submitted trigger
A submitted purchase requisition enters the approval workflow automatically, checked against live budget data before routing.
- 02
Check real-time budget availability ai
Current remaining budget for the relevant cost centre and category is checked, including the cumulative effect of other pending, not-yet-invoiced requisitions.
- 03
Determine approval tier ai
The requisition is routed to the correct approver based on amount and category, per your approval matrix, exactly as it would be without the budget check.
- 04
Present with budget context output
The approver sees the requisition alongside real-time remaining budget, with any projected overage clearly flagged rather than left for the approver to calculate themselves.
- 05
Approve, redirect or decline output
The approver makes an informed decision — approve, ask the requester to adjust, or decline — with full budget context, rather than approving blind.

Where this goes wrong if you get it wrong
- Checking only the current spent-to-date total against budget misses requisitions and purchase orders already approved but not yet invoiced — a department can look well within budget on paper while having already committed to spend that will push them over once those invoices land, and the check needs to include this pending commitment, not just historical actuals.
- A budget check that blocks every over-budget requisition automatically removes legitimate approver discretion for justified exceptions (a genuinely necessary emergency purchase) — the system's role is surfacing accurate budget context, not making the approval decision itself, and approvers need a clear, fast path to approve with awareness when that's the right call.
- Budget figures that update only monthly or on a lag give a false sense of real-time accuracy if presented without a timestamp — approvers need to know exactly how current the budget figure they're looking at actually is, especially in a fast-moving spend category where the number could meaningfully change within days.
- Multi-year or multi-phase projects with budget spread across periods need requisition approval to check against the correct period's allocation, not the full project budget as if it were all available immediately — a naive total-budget check can either block a legitimate current-period purchase or allow overspend against a future period's allocation.
Frequently asked questions
How is this different from our existing requisition approval workflow?
The core addition is real-time budget context — approvers see current remaining budget, including pending commitments, directly alongside the requisition, rather than approving based on the requisition details alone without visibility into whether the department can actually afford it.
Does this automatically block over-budget requisitions?
No, it flags the projected overage clearly so the approver can make an informed decision — approve with awareness, redirect, or decline — since legitimate business reasons for an occasional justified exception need to remain the approver's call, not an automatic block.
How does this account for spend that's already committed but not yet invoiced?
The budget check includes pending, approved-but-not-yet-invoiced requisitions and purchase orders, not just historical actuals, so the picture reflects true remaining budget rather than an optimistic view based only on what's been paid so far.
Can this work with budgets that span multiple periods or project phases?
Yes, it checks against the correct period or phase allocation rather than treating a multi-year project's total budget as fully available in the current period, which prevents both incorrectly blocking legitimate current spend and incorrectly allowing overspend against a future allocation.
