A purchase order can be approved without creating the maintenance record, fixed-asset entry, or link back to the request that justified it.
Asset-intensive purchases need context from the start: who requested them, what work they support, and whether they become fixed assets. 4Site carries requisition, approval, purchase order, and receiving. Optima takes the fixed-asset record when capitalization applies.

A clean purchase order can still leave equipment untracked when it arrives. The buyer raises the requisition in 4Site, the approver reviews it, and receiving is recorded against the order. Optima captures fixed-asset details once finance capitalizes the asset. Together they tie the buy to the asset, without making procurement and fixed-asset accounting the same job.
Requisitions, approvals, purchase orders, and receiving tied to the work that triggered the buy.
Fixed-asset detail for received equipment when finance capitalizes it, with value, depreciation, and purchase history attached.
The purchase may reach the ledger before the asset record exists. 4Site supports the purchasing record around it. Add Optima when received equipment becomes a capitalized asset.

Procurement starts before an asset exists. Accounting sees the cost. Operations may not see the purchase tied to the work. Maintenance may not see equipment added to a schedule. Finance may not see when received equipment becomes a fixed asset. The result is a purchase with no record ready.
