Telecom and low-voltage contractors bill in three different rhythms at once: progress invoices on cabling and security projects, a steady run of small service tickets for moves, adds and changes, and recurring charges for monitoring or support. Collections software for telecom and low-voltage contractors keeps all three moving without pulling project managers off the job.
Abivo is collections software for telecom and low-voltage contractors: its AI agent, Kate, follows up on overdue project, change order and service invoices by phone, text message and email, straight from your accounting system, and hands any dispute or judgment call to a person on your team with the full history attached.
Best for: structured cabling, low voltage, telecom installers, fiber contractors, security and access control integrators and audio visual installers that work as subcontractors to general and electrical contractors, or directly for building owners, property managers and IT departments, on net terms.
Is This Also Accounts Receivable Software for Structured Cabling, Low Voltage and Telecom Installer Companies?
Yes, for the part of accounts receivable that gets invoices paid. Your accounting or job costing system handles estimates, billing, job cost and cash application. Abivo connects to the accounting system and handles the follow-up on every overdue invoice, the step most low-voltage shops still do by hand. It works the same way for structured cabling contractors, telecom installers, low-voltage integrators and security and AV companies.
Why Is A/R So Hard for Telecom and Low-Voltage Contractors?
You are often a sub to a sub. On new construction, a cabling or security contractor may bill the electrical contractor, who bills the general contractor, who bills the owner. Your invoice waits on every pay application above it.
Project billing and service billing pull in opposite directions. A large building project produces a few big progress invoices with retainage and change orders attached. The service side produces dozens of small tickets for a new drop, a dead port, a camera swap or a badge reader that stopped working. The service tickets pile up.
Change orders are agreed in the field. An IT manager asks for more drops on a walkthrough, the crew installs them, and the change order is signed later, or never. When the invoice arrives, accounts payable has no approval on file and parks it.
Closeout paperwork drives the final payment. Final invoices and retainage often wait on test results, as-built drawings, labeling schedules or a punch list sign-off. If the paperwork is late, the money is late.
The requester is not the payer. Service work is requested by a facilities lead, an IT administrator or a property manager. Payment comes from a corporate AP team or a management company that needs a PO number and a site name before it will pay.
What Should Collections Software Do for a Low-Voltage Contractor?
Work the service tickets, not only the projects. Small move, add and change invoices are where the invoice count lives, and they age quietly.
Lead with the PO and the site. Property managers and corporate AP teams pay by PO number and building, so those belong in the first reminder.
Separate project billing from service billing. A progress invoice to a general contractor needs a different conversation than a service ticket to an IT department.
Surface change order approval problems early, so the person who sold the work can get the signature while the customer still remembers asking for it.
Follow recurring charges for monitoring or support agreements, so a lapsed payment is caught early.
Sync with your accounting system and log every call, message and promise to pay, so the office and project managers see the same history.
Which Invoices Should the Software Chase First?
Chase by invoice type, because each type stalls for a different reason.
Invoice type | Typical size | Why it stalls | What good follow-up does |
|---|---|---|---|
Move, add and change service ticket | Small, frequent | Requested by IT or facilities, sent to the wrong inbox, no PO on file | Confirms the payables contact, asks for the PO number, offers a payment link |
Project progress invoice to a general or electrical contractor | Large | Waiting on the upstream pay application, missing schedule of values detail | Confirms the invoice is in the current pay cycle, asks for a payment date, routes billing questions to your project manager |
Change order invoice | Mid | Approval never signed, scope questioned after the fact | Names the job and the change order, hands any scope dispute to your team |
Final invoice and retainage | Mid to large | Closeout documents, punch list or owner acceptance still open | Asks what the customer still needs, logs the answer, routes paperwork requests to the project lead |
Recurring monitoring or support charge | Small, monthly | Card or contact changed, building sold, nobody owns the bill | Reaches the current payer early, confirms the account is still active, sends a payment link |
Service and recurring rows hold the count, project and retainage rows hold the dollars, and change orders are where margin leaks.
How Does Autonomous Follow-Up Work on Project and Service Accounts?
An autonomous agent does the follow-up itself. Kate calls the customer's payables contact, says she is calling on behalf of your company, confirms the open invoices, answers routine questions such as "which building was this for" or "can you resend it with the PO number", and agrees on a payment date within the rules you set. We walk through a full call in how an AI agent calls customers about overdue invoices.
A typical cadence on an overdue service account:
Day 1 overdue: a friendly email with the invoice, the site, the PO number and a payment link.
Day 7: a text message or email to the payables contact, listing every open ticket on the account.
Day 14: a polite phone call to confirm the invoices were received and ask for a payment date.
Day 21 onward: calls and emails on a steady rhythm, each one logged in the account history.
At any point: a scope dispute, a change order question or a request to speak with someone goes straight to your team.
For project invoices to general and electrical contractors, the first contact confirms the invoice made it into the current pay cycle, the follow-up tracks that cycle, and anything about scope, retainage or closeout goes to the project manager.
How Do You Handle Change Order Disputes, Pay-When-Paid Delays and Missing Paperwork?
Three situations cause most of the friction for low-voltage contractors.
"We never approved those extra drops." A disputed change order is a conversation between your project manager and the customer, often with photos and a walkthrough record. Software should capture the objection and the PO and hand it to that person at once.
"We have not been paid by the owner yet." On subcontract work this is common. The useful follow-up is to ask when the upstream payment is expected, log that date, and call back on it, so the invoice does not drift for months without a single conversation.
"We are waiting on your closeout package." When the customer needs test results, as-builts or a punch list sign-off, the follow-up should record exactly what is missing and route it to the project lead. Our guide to construction, engineering and field services covers more of the project side.
What About Teams With Three or More People in Collections?
Larger low-voltage contractors often have an accounts receivable team. They spend their week on large project balances, pay applications and retainage, and the long tail of small service tickets waits.
An AI agent changes the split. Kate covers every overdue account on a weekly cadence, small service customers included, and your team spends its time on the work that needs judgment: pay applications, change order disputes, retainage, closeout and key general contractor relationships. The team does not get smaller. Its coverage gets complete.
What About QuickBooks, Sage Intacct and the Rest of Your Stack?
Many low-voltage contractors run estimating, job costing and dispatch in separate tools. Abivo connects to the accounting system: Kate reads open invoices and aging, follows up, and writes the outcomes back, so your books stay the source of truth. Integrations include QuickBooks, Xero, NetSuite, Sage Intacct, Microsoft Dynamics 365 Business Central and Chargebee, and a CSV upload covers anything else, including open invoice exports from your job costing or service management system. Details are on the product page.
What Results Should a Low-Voltage Contractor Expect?
Results depend on how old your overdue invoices are, how much of the ledger is tied up in subcontract pay cycles, and how many service customers have a working payables contact on file.
The closest proof is in service companies. OFS Group, a fire safety and appliance repair service company, put its overdue ledger in front of Kate and collected $842,518 in four months, with DSO down by more than 30 days. OFS is not a telecom or low-voltage contractor, but it shared the pattern that matters here: many small service invoices to business customers alongside larger project work. You can read how a close neighbor handles it in our guide to collections software for fire protection companies. We would still rather play you real call recordings than promise a number for your ledger.
What Should You Measure After Switching?
Share of invoices over 60 days, by billing type. Service tickets and recurring charges should fall first.
Unapproved change orders. How many invoices stall because the approval was never signed.
Retainage waiting on closeout. Each open balance, with the document or sign-off it is waiting on.
PO and site capture on service tickets.
Promises kept. Of the customers who gave a payment date, how many paid by it.
Practical Takeaways for Telecom and Low-Voltage Contractors
