Back to top

Growing SMBs need to separate three records that are often collapsed into one spreadsheet row: a request to buy, an internal stock transfer or fulfillment request, and a purchase order sent to a supplier.

The distinction matters. A purchase requisition records what a team needs before Procurement commits spend. An internal purchase order coordinates goods between a branch and a warehouse or central buying location. A supplier purchase order is the commercial order sent outside the business.

LineNow supports all three operational paths without pretending to be an enterprise spend-governance suite.

Quick answer

Use a purchase requisition when an employee or location needs Procurement to review a request before fulfillment or supplier commitment. Use an internal purchase order when one business unit is actually ordering stock from another. Use a supplier purchase order when the buyer is ready to commit an order to an outside vendor.

In LineNow, requisitions are separate records with configurable approval rules. Approval can be required for every request, requests above an estimated-total threshold, requests with enough line items, or requests containing unpriced items. Owners can assign default approvers or requester-specific approvers. This is operational request control, not a sequential multi-level approval chain or a departmental budget ledger.

The requisition workflow

A practical LineNow requisition workflow looks like this:

  1. A requester records the needed item, quantity, need-by date, estimated price, and notes.
  2. LineNow evaluates the business unit's approval rules.

Read before ordering

A dense operator briefing for teams that need sharper buying, cleaner supplier follow-up, and fewer expensive surprises.

  • If approval is required, an eligible approver sends the request to Procurement or returns it to the requester with a reason.
  • Procurement reviews the approved request and decides how to fulfill each item.
  • Available goods can be issued from stock; missing goods can move into sourcing, an RFQ, or a supplier PO.
  • Receiving records what arrived and updates inventory.
  • Accounting receives the purchasing context while remaining in the finance system.
  • This is a good fit when:

    • many employees request spend
    • a buyer needs to review demand before contacting suppliers
    • approval should depend on request value, item count, or missing pricing
    • the stockroom may fulfill some items before Procurement buys the rest
    • the business wants an audit trail outside email and Excel

    If the company also needs live departmental budgets, cost-center enforcement, delegated approval queues, or sequential multi-level chains, it needs a broader spend-governance product alongside or instead of this operational workflow.

    The internal PO workflow

    An internal purchase order workflow looks like this:

    1. Store manager creates an order to the central warehouse or main buying location.
    2. Warehouse or central buyer approves, edits, or fulfills it.
    3. Warehouse consolidates demand from multiple stores.
    4. Buyer places external supplier POs only when needed.
    5. Supplier replies update the external PO.
    6. Warehouse receives goods.
    7. Store receives allocation.
    8. Accounting sees the final supplier bill and location-level allocation.

    This is a strong fit when:

    • locations regularly need product
    • a central warehouse or main store supplies branches
    • the same buyer controls supplier relationships
    • the business buys inventory, ingredients, or hard goods
    • store managers need a simple workflow
    • accounting needs cleaner location-level spend

    The internal PO is not pretending the warehouse is an outside vendor. It is using the PO as the shared operational record between branch, warehouse, buyer, receiver, and accounting.

    Why SMBs ask for requisitions

    SMBs usually ask for requisitions because they want four controls:

    Visibility. "I want to know what stores are asking for before they call suppliers."

    Approval. "I want a buyer or manager to review requests before spend is committed."

    Consolidation. "I want the warehouse to combine location demand into fewer supplier POs."

    Accounting traceability. "I want to know which location consumed the spend."

    Those are valid needs. They do require a distinct request record when Procurement must review the need before deciding how to fulfill it. They do not automatically require an enterprise procure-to-pay rollout.

    When internal POs are the right record

    Internal POs are usually better when the request is actually a replenishment order.

    Example:

    • Branch needs 10 cases from the warehouse.
    • Warehouse has 6 cases.
    • Warehouse fulfills 6 and adds 4 cases to supplier demand.
    • Central buyer places supplier PO.
    • Supplier short-ships 1 case.
    • Warehouse receives 3 cases.
    • Branch gets updated allocation.

    A requisition can capture the branch's original need, but the internal PO is the right fulfillment record once the warehouse agrees to supply it. The two should stay linked rather than being collapsed. The work after approval includes fulfillment, supplier changes, receiving, allocation, and upstream reconciliation before accounting sees the final supplier bill.

    When requisitions are the right record

    Use a requisition whenever the business needs to review a need before committing stock or supplier spend, including requests inside the normal inventory loop.

    Examples:

    • new equipment or replacement parts
    • PPE, tools, and facilities supplies
    • stockroom consumables and packaging
    • a new or unpriced physical item
    • replenishment that needs approval before sourcing
    • goods that Procurement may fulfill from stock or buy from a supplier

    Services, software, marketing spend, and other indirect purchases often need policy, budget, and contract controls more than stockroom fulfillment. LineNow can route operational approval based on a physical-goods request; it does not maintain enterprise budget ledgers or enforce contracts.

    The central warehouse pattern

    For multi-location operators, the central warehouse pattern is often the cleanest middle ground.

    Each store treats the warehouse as its approved source. The warehouse can:

    • confirm available inventory
    • adjust quantities
    • reject or backorder items
    • consolidate supplier demand
    • allocate costs
    • communicate expected arrival dates

    The outside supplier relationship stays centralized. Store managers get a simple workflow. Accounting gets a cleaner record.

    See Central Warehouse Procurement for Multi-Location Retail for the full model.

    How this changes supplier buying

    Without internal POs:

    • Store A calls Supplier 1.
    • Store B texts Supplier 1.
    • Store C emails Supplier 2.
    • Warehouse discovers demand later.
    • Accounting receives supplier invoices with unclear location context.

    With internal POs:

    • Store A, B, and C order from the warehouse.
    • Warehouse sees total demand.
    • Buyer places one supplier PO or fulfills from stock.
    • Supplier reply creates a reviewable order update.
    • Receiving confirms what arrived.
    • Accounting sees the final record.

    The supplier does not need to change. The buyer's workflow changes.

    What to track

    For internal POs, track:

    • requesting location
    • fulfilling location or warehouse
    • requested quantity
    • approved quantity
    • fulfilled quantity
    • backordered quantity
    • external supplier PO link where applicable
    • expected arrival
    • receiving status
    • internal markup or allocation, if used
    • final accounting treatment

    For external supplier POs, track:

    • supplier
    • line items
    • pack size
    • MOQ
    • supplier cost
    • supplier reply changes
    • receiving discrepancies
    • invoice documents
    • QuickBooks or Xero handoff status

    If you are still drafting supplier POs by hand, the Purchase Order Generator covers the external-PO fields above.

    The internal PO and external PO should be connected but not collapsed. One represents branch demand. The other represents supplier commitment. The living PO record is what keeps those states from drifting apart.

    The accounting implication

    Internal POs help accounting because they preserve intent and allocation.

    The accountant can see:

    • which branch requested product
    • which supplier created the cost
    • what the warehouse fulfilled
    • whether an internal markup applied
    • what should hit each location/class/category
    • why the vendor bill differs from the original supplier PO

    Finance determines the permitted allocation and legal-entity treatment. An internal markup within one company is not new group revenue; inventory valuation and intercompany accounting belong in the books. Location context in an internal PO does not prove that every allocation posts automatically.

    Where LineNow fits

    LineNow is a lightweight procurement management system for physical-goods teams moving requisitions, approvals, RFQs, quote comparison, supplier communication, purchase orders, receiving, GRNs, and basic inventory out of email and Excel.

    The practical setup:

    • requesters submit a distinct requisition with items, quantities, need-by dates, estimates, and notes
    • owners configure approval for every request or only requests triggered by estimated total, item count, or unpriced items
    • default approvers or requester-specific approvers send requests to Procurement or return them with a reason
    • Procurement can issue available inventory, source missing items, compare supplier quotes, and create supplier POs
    • supplier replies create reviewable order-state updates
    • receiving records discrepancies and updates inventory
    • accounting stays in QuickBooks, Xero, or another finance system, with future integration handled at the accounting boundary

    The Whitmans customer account reports less manual supplier back-and-forth after adopting the shared order workflow. Its reported before-and-after descriptions have measurement limits; use your own comparable order sample to measure review time and unresolved exceptions.

    For many SMBs, this is the right level of control: a real requisition and approval record tied to the buying workflow, without the cost and administration of sequential multi-level approvals, departmental budget ledgers, contract lifecycle management, or enterprise policy enforcement.
