What this role should do

Track billed work, retained amounts, approvals, and release conditions so AP can prepare the record while an authorized employee decides what is payable.

A practical example

Start with a working record that another reviewer can follow without opening a private inbox. For an invoice where part of the billed amount is withheld until a contract condition is met, keep the contract terms, invoice, schedule of values, prior certificates, approvals, receipts, and payment history together by stable identifiers. A contractor bills $50,000 for approved work and shows $5,000 as retainage. The reviewer needs the gross work, current retention, prior retention, tax treatment, and cumulative totals, not just a net $45,000 payable line. If an email introduces a new link, contact, or payment instruction, stop and use the company security and verification route. Do not authenticate the request with details taken from the same message.

This step is preparation, not approval. The specialist can collect and compare the contract terms, invoice, schedule of values, prior certificates, approvals, receipts, and payment history, while the project, contract, or finance owner answers the question that changes money, accounting, access, or supplier data. Before work begins, agree on the authoritative source, the fields the specialist may prepare, the stop conditions, and the employee who can clear each exception. Link the written rule from the queue rather than asking the processor to remember it. For quality review, sample one ordinary item and one exception. Check whether a second reviewer can reproduce the comparison and identify the decision owner.

Capture gross, retained, and net amounts

Use the source record even when the queue is busy. For an invoice where part of the billed amount is withheld until a contract condition is met, a familiar supplier name or expected amount is not enough to fill a missing field. Record the invoice exactly as issued, including the gross billed amount, current retainage, prior retainage, taxes, credits, and requested net amount. The components should add back to the supplier total. This record is also useful when the item returns weeks later. Dates, versions, and identifiers prevent the next person from rebuilding the history from memory.

Write the exception in plain terms: what the source says, what the other record says, the amount or item affected, and who must respond. Keep the earlier value after a correction. Do not post only the net figure if that would hide the retained obligation or distort project reporting. Route the proposed accounting treatment to the employee who owns it. The handoff should include a current state, a named next owner, and a review date. If a source is missing, say so instead of borrowing a value from a prior transaction.

Tie the calculation to contract evidence

Write the exception in plain terms: what the source says, what the other record says, the amount or item affected, and who must respond. Keep the earlier value after a correction. Link the clause, approved schedule, or other controlled instruction that states how retention works. Record the version and effective date because project terms can change. The handoff should include a current state, a named next owner, and a review date. If a source is missing, say so instead of borrowing a value from a prior transaction.

Close the step from controlled evidence. A message saying the issue is handled should point to the approved decision or system result before the status changes. A familiar percentage from an earlier invoice is a comparison, not authority. Show any difference between the current calculation and the documented rule. Access should follow least privilege: give the support role only the systems and actions needed for this task. Approval and payment release stay with authorized company employees.

Check cumulative values

Close the step from controlled evidence. A message saying the issue is handled should point to the approved decision or system result before the status changes. Prepare a simple rollforward of work billed, retainage withheld, retainage released, payments, and open balances. Compare it with prior approved applications and the supplier statement. Access should follow least privilege: give the support role only the systems and actions needed for this task. Approval and payment release stay with authorized company employees.

Start with a working record that another reviewer can follow without opening a private inbox. For an invoice where part of the billed amount is withheld until a contract condition is met, keep the contract terms, invoice, schedule of values, prior certificates, approvals, receipts, and payment history together by stable identifiers. Keep each source separate when totals disagree. The AP specialist should identify the break, not force the records to match by editing an earlier amount. If an email introduces a new link, contact, or payment instruction, stop and use the company security and verification route. Do not authenticate the request with details taken from the same message.

Treat release as a new decision

Start with a working record that another reviewer can follow without opening a private inbox. For an invoice where part of the billed amount is withheld until a contract condition is met, keep the contract terms, invoice, schedule of values, prior certificates, approvals, receipts, and payment history together by stable identifiers. A request to release retainage needs its own evidence and approval. Capture the amount, project or milestone, requested date, and source of the release request. If an email introduces a new link, contact, or payment instruction, stop and use the company security and verification route. Do not authenticate the request with details taken from the same message.

This step is preparation, not approval. The specialist can collect and compare the contract terms, invoice, schedule of values, prior certificates, approvals, receipts, and payment history, while the project, contract, or finance owner answers the question that changes money, accounting, access, or supplier data. Completion language, lien documents, tax questions, and contract interpretation belong with the designated company owner. AP can index the documents and state what is missing. For quality review, sample one ordinary item and one exception. Check whether a second reviewer can reproduce the comparison and identify the decision owner.

Leave a reviewable trail

This step is preparation, not approval. The specialist can collect and compare the contract terms, invoice, schedule of values, prior certificates, approvals, receipts, and payment history, while the project, contract, or finance owner answers the question that changes money, accounting, access, or supplier data. Record who approved the invoice, who authorized any release, and which system transactions followed. Preserve rejected and corrected versions with their timestamps. For quality review, sample one ordinary item and one exception. Check whether a second reviewer can reproduce the comparison and identify the decision owner.

Use the source record even when the queue is busy. For an invoice where part of the billed amount is withheld until a contract condition is met, a familiar supplier name or expected amount is not enough to fill a missing field. Before closing, confirm that the outstanding retainage in the register agrees with the approved records. Put unresolved differences back with a named owner and date. This record is also useful when the item returns weeks later. Dates, versions, and identifiers prevent the next person from rebuilding the history from memory.

Put the routine into service

Write the exception in plain terms: what the source says, what the other record says, the amount or item affected, and who must respond. Keep the earlier value after a correction. Begin with a small sample from the actual queue. Review the packet with the project, contract, or finance owner, correct unclear labels, and confirm that the escalation reaches someone who can answer. Add volume only after the record works for both routine items and exceptions. The handoff should include a current state, a named next owner, and a review date. If a source is missing, say so instead of borrowing a value from a prior transaction.

Close the step from controlled evidence. A message saying the issue is handled should point to the approved decision or system result before the status changes. For related implementation detail, use the invoice data capture service page to define the task boundary and the contact page to discuss a Philippines-based support role. Those pages help turn this control into a scoped handoff rather than a broad promise to handle AP. Access should follow least privilege: give the support role only the systems and actions needed for this task. Approval and payment release stay with authorized company employees.

Continue with invoice data capture and the contact and scoping page.
