Accounts payable today

Ten steps. Ten places to slip.

The work on one invoice takes minutes. It waits for days, and every hand-off is a place to lose money.

  1. Intake Lost in an inbox or a portal
  2. Keying Typos. Wrong vendor.
  3. Duplicates Paid twice
  4. Matching Paid for goods never received
  5. Coding Wrong job. Wrong GL.
  6. Approval Sits for days
  7. Vendor changes Bank fraud by email
  8. Pay run Late fees. Lost discounts.
  9. Month-end Bills nobody booked
  10. Vendor calls “Where is my money?”

Construction payables are messy is messy

  • Overbilled contracts. Paid past the subcontract
  • Missing waivers. Paid, no lien waiver
  • Retainage errors. Held wrong, released early
  • Late job cost. PM sees costs weeks late

NextChecks the AP inbox first thing every morning

01Intake

Collect pay apps and invoices

Pay apps, supplier invoices and delivery tickets arrive in five places. The agent checks each one every morning.

  • AP inbox: pay apps, invoices and the waivers attached to them
  • Subcontractor pay-app portal: new applications by project
  • Supplier portals: material invoices and monthly statements
  • Field photos of delivery tickets from the superintendent
  • Scanned mail from the office and the job trailer

Agent does it

02Read

Read the pay application

The agent reads the G702 and G703 line by line and re-adds the math before anything is entered.

  • Contract sum, change orders and contract sum to date
  • Each schedule of values line: previous, this period, to date
  • Stored materials, retainage and previous certificates
  • Current payment due, re-added from the lines
  • Any field that does not agree with Sage is shown to you

Agent does itYou confirm the one field that does not agree with Sage.

03Read

Vendor and duplicate check

Before entry, the agent confirms the vendor is set up and the same application has not been entered already.

  • Vendor is active in Sage with a W-9 on file
  • Remit-to address and 1099 type match the vendor file
  • Same application number and period already entered? It stops
  • A mailed copy of an emailed pay app is skipped

Hard stop

04Compliance

Check waivers, insurance and license

No sub is paid without current insurance and every lien waiver. The agent reads each document and tells you what is missing.

  • COI: general liability and workers' comp, with expiry dates
  • Conditional waiver for this draw, amount and through-date read
  • Unconditional waiver for the previous payment
  • Sub-tier waivers from the sub's suppliers
  • Contractor license is active

You decideYou decide what to do when a document is missing: hold the pay app or approve it and hold the payment.

05Match

Match to the subcontract

Every line of the pay app is compared with the schedule of values in Sage and with the PM's progress.

  • Scheduled values match the subcontract, line by line
  • Previous billing matches what Sage has already paid
  • Billed percent is not ahead of the PM's progress
  • Nothing is billed past its contract line
  • Lines that are not on the subcontract are set aside

Agent does it

06Match

Change orders: approved only

A change order is payable only after it is signed. The agent checks the log and holds anything still pending.

  • Each billed change order is looked up in the change order log
  • Approved and executed: payable on this draw
  • Pending or unpriced: left off, never paid on a promise
  • The sub is told what was left off and why

You decideYou decide: approve the contract work without the pending change order, or send the pay app back.

07Match

Hold retainage at the contract rate

Retainage is recalculated at the subcontract rate, held on its own line and tracked per subcontract.

  • Rate comes from the subcontract, not from the pay app
  • Held on its own line to 2150 Retainage payable
  • Running balance per subcontract, application by application
  • A sub that bills the wrong retainage is corrected and told
  • Released only on your sign-off, never by the agent

Agent does itRetainage release always waits for your sign-off.

08Match

Three-way match on materials

Material invoices are matched to the PO and to the delivery ticket the superintendent signed on site.

  • Reads the signed ticket, including handwritten notes
  • Quantity billed against quantity signed for on site
  • Unit price against the PO or the quote
  • Delivered to the right job, coded as the PO says
  • A shortage is short-paid only with your approval

Agent does itThe PM approves a short-pay when the site received less than was billed.

09Code

Costs with no PO

Rentals, fuel and small tools rarely have a PO. The agent checks them against your logs and codes them by your rules.

  • Rental on-rent and off-rent dates against the site rental log
  • Rate against the vendor's price sheet
  • Job named on the invoice, or found from the delivery address
  • Cost code picked by your written rule, with the reason shown
  • The PM confirms anything the rules do not cover

You decideThe PM confirms the cost code when there is no PO.

10Code

Code to job, cost code, cost type

Every line is coded the way your job cost report needs it: job, cost code, cost type and commitment line.

  • Job, extra, cost code and cost type on every line
  • Tied to the commitment line so committed cost comes down
  • Retainage on its own line to 2150
  • Sales and use tax handled by your rule for the job
  • Equipment and overhead go to the GL, not to a job

Agent does it

11Approve

Route to the right approver

The pay app goes to the PM first and to the project executive over the limit. Nobody is skipped and nobody is chased by hand.

  • Approver comes from your approval matrix: job, type and amount
  • PM approves on a phone, with the checks already done
  • Over the PM's limit, the project executive approves too
  • A reminder after one day, escalation after three
  • Every decision is recorded with the time and the reason

You decideThe PM approves. Over $25,000, the project executive approves as well.

12Post

Enter it in Sage 300 CRE

Once approved, the invoice is entered the same day, with the PDF attached, so job cost is never weeks behind.

  • Typed into Sage screens the way your AP clerk does it
  • Pay app PDF, waivers and the approval attached
  • Committed cost comes down, actual cost goes up, same day
  • Pay status set from the compliance and pay-when-paid checks
  • Batch total checked against the invoice before posting

Agent does it

13Pay

Pay-when-paid and the owner draw

Sub costs are rolled into the owner's pay application. A pay-when-paid sub is held until the owner's money is in.

  • Approved sub billing feeds the owner draw worksheet by division
  • Each sub invoice is tied to its owner draw
  • Pay-when-paid invoices stay on hold until the owner pays
  • When the deposit lands, the hold comes off and you are told

Agent does it

14Pay

Prepare the pay run. You release it.

The agent builds the pay run and stops. A person releases every payment, and anything missing a waiver stays out.

  • Selected by due date and pay-when-paid status
  • Joint checks prepared where an agreement is on file
  • Missing waiver or expired insurance: held, with the reason
  • Vendor bank details checked against the vendor file
  • The controller releases. The agent never moves money.

You decideThe controller reviews the run and holds the button to release it.

15Pay

Remittance, waivers and answers

Each sub gets a remittance and a request for the unconditional waiver. Payment questions are answered the same day from Sage.

  • Remittance shows what was paid, held and left off, and why
  • Unconditional waiver requested for the amount just paid
  • Waivers that come back are read and filed to the subcontract
  • "When will we be paid?" answered from the pay run and holds

Agent does it

16Close

Month-end: accruals and tie-outs

At month-end the agent lists what is owed but not billed, ties retainage and aging to the GL, and hands you the schedule.

  • Work in place not yet billed, by job, for the accrual entry
  • Retainage payable by subcontract tied to GL 2150
  • AP aging by job tied to GL 2000
  • Open commitments and unapproved change orders listed for the WIP
  • 1099 totals kept current for year-end

Agent does itThe controller reviews the schedule and posts the accrual.

17Close

The record of every invoice

Every invoice keeps its trail: where it came from, what was checked, who approved it, and a video of the agent's work.

  • Source: inbox, portal, scan or field photo
  • Each check and its result, with the screen it was done on
  • Who approved, when, and what they saw
  • What was held, left off or short-paid, and why
  • A daily sign-off of what is done and what is waiting

Agent does itYou sign off the day's run and see what is still waiting on a person.

You stay in control

It stops. It asks you.

Mismatch, missing document, over the limit, money about to move. One window with the evidence, and the decision is yours.

FAQ

Questions controllers ask us

Do we have to buy new software or connect anything?

No. The agent works in the software you already use, with the same screens, keyboard and mouse your team uses, under logins you give it. Nothing to replace and nothing to integrate.

How is the agent built?

You explain the job the way you'd train a new hire: talk or type, and hand over your SOP and a few real examples. Then it does a real one live while you watch and correct it. Your process is saved as a flowchart and a written procedure, and every run follows the version you approved.

Will it pay subs on its own?

No. It prepares the invoice and the pay run. A person releases every payment, retainage is only released by your team, and bank-detail changes always go through your call-back check.

Does it read AIA pay applications?

Yes. It reads the G702 summary and each G703 line, checks the math, and compares scheduled value, previous billings and this period against the subcontract and approved change orders in your ERP.

How does it handle lien waivers and insurance?

Before an invoice goes on a pay run it checks that the waiver your process requires is on file and that the COI has not expired. If either is missing it holds the payment and asks the sub for it.

Can we change the process later?

Any time. Add a step, change a rule, move an approval or drop one. Tell the agent what changed, review the new flowchart and save it as a new version.
