What is an AI accounts receivable follow-up agent for engineering firms?
An AI accounts receivable follow-up agent for engineering firms helps project accountants connect client invoices to approved milestones, deliverable acceptance, contract schedules, reimbursable expense records and posted payments. It can surface overdue invoices, partial payments, retainage, disputed scope references and missing client approvals for the project manager or finance lead. For firms billing across multiple disciplines and offices, work can be routed by project, client and service line. The agent prepares concise follow-up drafts grounded in the firm’s documented terms. Staff verify work acceptance, expenses, contract conditions, invoice amounts and recipient before messaging a client or updating a ledger. It does not certify engineering work, interpret contracts, approve scope changes, determine liability or initiate collections.
Engineering receivables by project and deliverable
Track milestone invoices
Connect client invoices to project phases, approved schedules, deliverable acceptance and payment records.
Route retainage and scope questions
Surface contract references, client comments and payment applications for review by project finance and authorized managers.
Separate billing by discipline and office
Organize accounts by client, project, engineering discipline or office using the firm’s approved ownership rules.
Prepare evidence-based client follow-up
Draft a professional reminder that references the invoice and approved project context, with human review before sending.
Where it can help
A client has not paid a milestone invoice
Assemble the invoice, accepted deliverable reference, contract schedule and prior payment history for the project accountant.
A payment excludes retainage
Identify the retainage reference and relevant payment terms for authorized finance staff to check.
A client disputes reimbursable expenses
Link the invoice line to documented expense and approval references so the project owner can validate the record.
A scope change affects billing
Route the change request and related invoice to the project manager; staff confirm whether an approved amendment exists.

A step-by-step workflow your team can review before launch.
Define client portfolios and service lines

Map project billing records
Connect project identifiers to contracts, milestones, deliverables, invoices, expenses, retainage and posted payments.

Clear boundaries before launch
What it will not do
The agent organizes project receivables information and prepares drafts for staff review. It does not certify engineering work; approve deliverables, expenses, scope changes or contract amendments; interpret legal obligations; determine liability; release retainage; post payments or credits; initiate collections; or contact clients without authorization. Project managers and finance staff verify contract terms, milestone acceptance, expenses, amount and recipient before action. Integrations and access are separately scoped and approved.
How success is measured
Track milestone invoice-to-payment matching time, retainage items routed with contract references, expense disputes reviewed, missing client approvals surfaced, reminders approved before sending and outstanding project balances reconciled. Compare by discipline, client and project type against the firm’s baseline.
Frequently asked questions
What does an accounts receivable agent do for an engineering firm?
It connects client invoices to project milestones, deliverable references and payments, then routes exceptions and drafts staff-reviewed follow-up.
Can it track milestone billing and retainage?
A tailored workflow can connect invoices to approved schedules, retainage terms, payment applications and posted receipts.
Does it approve engineering deliverables or scope changes?

Can it validate reimbursable expenses?
It can link invoice references to documented expense approvals, but staff verify whether an expense is billable under the contract.
Will it contact clients automatically?
No. It prepares a draft; staff confirm the contract context, balance and recipient before sending.
Can multiple offices or engineering disciplines be included?
Yes. Billing queues can be configured by office, discipline, client or project type using approved ownership rules.
What does the $300/month starting price include?
Tranki solutions start at $300 USD/month. A tailored proposal defines scope and deliverables; integrations, usage, hosting and ongoing support may be scoped separately.
