Decide whether another staffing booking fits the client’s approved funding. Reconcile hours already worked, work already promised and the next request before releasing more assignments.
The client’s PO shows an unbilled balance, so a scheduler confirms another week. Later, the agency discovers that several workers have already consumed part of that balance—and other shifts were promised by a different account team.
A staffing purchase-order limit check answers a narrower question than “is the client within budget?” It establishes how much of a particular PO or line remains available for additional work after existing activity and commitments are accounted for. Run it before confirming extra hours, extending an assignment or adding another worker to a shared order.
This is a recommended operating process for staffing schedulers and account managers working with the client’s buyer and budget owner. It sits at Ready → Assign, then repeats during Manage as actual hours replace estimates. It does not calculate wages, determine contractual payment rights or replace the purchasing system.
Find the limit that actually governs the booking
Start with the approved PO, amendments and assignment terms—not an amount copied into a recruiter’s notes. Record the client entity, supplier, PO number, affected line, currency, validity dates, approved amount and which assignments may charge against it. Establish whether the restriction applies to money, hours, a line, the whole order or several limits together.
A general budget approval does not necessarily amend the purchase order. For example, Stanford’s purchase-order terms, Article 4, require prior written approval and an issued PO change order before exceeding the specified maximum cost. That is one organization’s contractual provision, not a rule for every staffing client. Have the authorized buyer establish what your actual terms require.
Use the staffing job-order intake checklist to establish the initial commercial record. This recurring check starts when that approved order is being used, not when the initial request is still incomplete.
Build a capacity bridge, not just an invoice balance
Name one coordinator for the affected PO or line. Billing supplies invoice activity, account managers identify unbilled work, schedulers supply existing future bookings, and the client’s authorized owner confirms the limit and any amendment. Give every input a source reference and refresh time.
The following worksheet is an operational estimate for deciding on new bookings. It is not a definition of “available budget” in any particular accounting or VMS product. First have finance map its reports to these buckets; otherwise a report that already includes commitments could cause them to be subtracted twice.
| Bucket | Include | Check before using it |
|---|---|---|
| A. Approved capacity | Current authorized amount for the exact scope, line and currency | Buyer confirms issued amendments, effective dates and restrictions |
| B. Invoiced activity | Invoice amounts consuming that capacity under the client’s rules | Billing reconciles statuses; apply only verified credits or reversals |
| C. Worked but not in B | Actual work already performed, including time awaiting review, estimated at the applicable bill terms | Link timesheets to invoice lines; isolate disputed or incomplete time |
| D. Confirmed future work | Unworked portions of bookings already released against the same capacity | Replace completed portions with actual activity; do not count them in both C and D |
| E. Other expected in-scope charges | Applicable expenses, fees or other expected charges not already included above | Confirm the PO’s treatment of taxes, expenses and fees; prevent duplication |
| F. Proposed new work | The request being decided, priced for its dates and expected billable components | Keep separate from confirmed work until released; disclose competing requests |
Estimated headroom before this request = A − B − C − D − E. Compare F with that headroom and any separate hour, date or line restrictions. A positive number is only one readiness check; it does not approve the booking by itself.
Count each piece of work once
Use assignment, work date, time-entry reference and invoice-line reference to match records. If a timesheet has been partly invoiced, put only its uninvoiced remainder in C. When a future shift is completed, move its exposure out of D and replace it with the observed work in C or B. Do not retain the full original forecast as well.
Submitted time still consumes estimated capacity even when a client reviewer has not responded. A missing clock-out or unknown bill rate is an unresolved input, not zero cost. Mark the affected amount and have the owner resolve it before relying on the result.
Use bill costs without confusing them with worker pay
A client PO generally needs the applicable client-facing charge basis, not simply the worker’s pay rate. Confirm the approved rate version, overtime billing treatment, shift premiums, dates and relevant expenses. If charges use multiple currencies or variable terms, finance must establish a consistent basis; a scheduler should not invent an exchange rate or assume every hour costs the same.
Keep the separate worker-week overtime booking check. Enough PO capacity does not establish that a worker’s combined assignments meet the employer’s scheduling and wage rules.
Work through a shared-order example
Illustrative example, not a customer result: A client has approved $20,000 for one staffing PO line. Assume one currency, fixed bill rates and no additional charges beyond the amounts shown. Billing and operations reconcile the following mutually exclusive amounts:
- Invoiced activity: $12,000.
- Worked but not yet invoiced: $2,400.
- Already-confirmed future shifts: $3,600.
- Other expected in-scope charges: $600.
The invoice-only view suggests $8,000 remains. The prospective booking view leaves $20,000 − $12,000 − $2,400 − $3,600 − $600 = $1,400 before new work.
A request for 40 additional hours at a $40 bill rate costs $1,600 on these assumptions. It exceeds that headroom by $200. The coordinator records the request as Awaiting commercial decision, rather than confirming it because the latest invoice balance looked sufficient.
The client might approve a documented increase, reduce the proposed work or decide not to proceed. The account manager cannot choose on the buyer’s behalf. If scope is reduced, confirm the revised hours and operational feasibility; do not quietly shorten an already-promised worker schedule.
Release one decision against one refreshed position
Use explicit states: Check required, Evidence incomplete, Awaiting client amendment, Ready for release, Released or Not proceeding. “Client said okay” is not a substitute for the evidence required by the actual purchasing arrangement.
- Coordinator reconciles. Record the A–F amounts, sources, unknowns and applicable limit. Show all assignments drawing on the same capacity, not just the requester’s team.
- Authorized owner decides. The account manager obtains the buyer’s decision and required issued documents. Keep any conditions visible.
- Scheduler refreshes before release. Check for new time, other bookings, rate changes or amendments since the review. Recalculate when the evidence changes.
- Record the commitment immediately. Add the approved new booking to future confirmed work and record who released which hours, dates and version. Notify the relevant client and agency owners through their agreed process.
Do not let two requests spend the same headroom
In the example, two schedulers might each propose a separate $800 booking. Each request appears to fit $1,400; together they cost $1,600. A shared snapshot alone does not prevent this collision.
Use the purchasing or scheduling system’s verified reservation control if one exists. Otherwise designate a single release owner for that PO line, maintain a common pending-request list and recheck the current commitments before each confirmation. Do not describe this manual procedure as an atomic system lock. If the team cannot establish which work has already been released, keep the next request unconfirmed while it reconciles the position.
When the limit is reached—or work has already happened
A low balance should trigger a decision early enough for the client’s real amendment lead time. Set any warning threshold under company policy using expected staffing burn and approval time; a percentage copied from another company is not a guarantee that action will finish before capacity runs out.
For new work, route the proposed continuation, reduced schedule or cancellation to authorized owners. State who will communicate any change, its effective time and any worker or client commitments requiring review. Do not turn a commercial hold into an unexplained absence on the rota.
For work already performed, preserve the actual hours and escalate the billing or funding exception separately. Do not delete time, move it to a fictitious assignment or mark it unworked to make the PO fit. The U.S. Department of Labor’s recordkeeping guidance describes accurate hours-and-pay records for covered nonexempt employees. The responsible payroll owner must address applicable wage obligations; this commercial capacity worksheet is not permission to defer them.
Send actual time through the staffing timesheet approval workflow while the account manager and buyer resolve the PO exception. Record the commercial decision, revised document and residual billing follow-up rather than declaring the case fixed when someone merely requests an increase.
Where Workhint fits
Workhint’s Workflow Engine describes role-based approval routing and requirements for details, files, notes or approvals before work progresses. Those building blocks are relevant to collecting the capacity worksheet and routing an exception to the appropriate reviewer.
The Staffing Managers solution describes allocation to shifts, clients and projects based on factors including rate, availability and manager review. That provides the staffing context for a pre-booking commercial review.
The calculation, record-matching and release procedure here are a proposed operating design to validate. These pages do not establish native PO-balance calculation, accounting synchronization, automatic spending enforcement or a reservation lock. Keep the purchasing system as the authority for approved capacity and test how any proposed workflow receives current evidence before relying on it.
FAQ
Is the unbilled PO balance available for another assignment?
Not necessarily. Work already performed but not invoiced, existing future bookings and other applicable charges may consume it. Reconcile those amounts without double counting and check the actual line, dates and terms.
Does a client manager’s email authorize a PO increase?
Only the applicable authority and purchasing rules can establish that. Obtain the required buyer decision and issued amendment; do not assume an informal message changes the order.
Can unused funding on another line cover this booking?
Do not assume it can. The buyer must establish whether reallocation is permitted and complete the required approval or amendment. Preserve the correct assignment and charging references.
What closes a capacity exception?
A recorded decision plus evidence of its execution: a verified amendment and refreshed booking release, an agreed reduced request, or a confirmed decision not to proceed. Keep any already-worked time and unresolved billing follow-up visible under named owners.
