Electrical, plumbing and HVAC supply houses run two businesses through the same door: counter sales, where a contractor grabs fittings, wire or a condenser motor at seven in the morning and signs a charge ticket, and account sales, where the same contractor buys a full job package on a quote and pays when the job pays. Collections software for supply houses keeps both kinds of balance current without turning counter staff into collectors.
Abivo is collections software for supply houses: its AI agent, Kate, follows up on overdue contractor charge accounts, job accounts and counter tickets by phone, text message and email, straight from your accounting system, and hands any dispute, return question or judgment call to a person on your team with the full history attached.
Best for: electrical wholesalers, plumbing supply houses, HVAC distributors and hydronics and waterworks suppliers that sell to contractors, builders, property managers and facility teams on charge accounts, often across several branches, and have more open accounts than the credit desk can call.
Is This Also Accounts Receivable Software for Electrical Wholesalers, Plumbing Supply and HVAC Distributors?
Yes, for the part of accounts receivable that gets invoices paid. Your distribution ERP handles quotes, pricing, counter tickets, invoicing, statements and cash application. Abivo connects to the accounting system and handles the follow-up on every overdue invoice, the step most supply houses still leave to a credit manager with a phone list. It works the same way for electrical wholesalers, plumbing supply houses, HVAC distributors and trade supply companies.
Why Is A/R So Hard for Supply Houses?
Counter tickets multiply faster than anyone can track. A contractor's crew might stop at the counter several times a week, and each stop is a charge ticket signed by a tech or apprentice, often with no PO.
Contractors pay from the statement, not the invoice. Many trade customers wait for the monthly statement, then pay what they recognize and skip what they do not. A ticket signed by a helper the office has never heard of is the one that gets skipped.
Job accounts move on someone else's schedule. A switchgear package, a plumbing rough-in or a rooftop unit replacement is billed to a job account tied to a project. The contractor pays when the builder or owner pays, and the balance drifts while the main account looks fine.
Seasons stretch the ledger. HVAC distributors carry heavy equipment balances into peak season. When everyone is busy installing, nobody reconciles statements.
Returns and credits blur the balance. Contractors over-order and bring back the rest. If a return is credited late, the contractor sees a paid invoice and you see an open one.
What Should Collections Software Do for a Supply House?
Treat counter and account sales differently. A small counter ticket needs a quick, friendly nudge and a payment link. A job account needs a conversation about the project and the payment date.
Work from the statement the contractor actually sees, and confirm every open ticket on the account in one contact rather than a string of separate reminders.
Name the job on every job account message, so the contractor knows exactly which project the balance belongs to.
Ask for the PO number on tickets that went out without one.
Capture the reason for every short payment, then route pricing, returns and branch questions to the right person.
Sync with your accounting system and log every call, message and promise to pay, so branches and the credit desk 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 |
|---|---|---|---|
Counter charge ticket | Small, frequent | Signed by a tech or helper, no PO, office does not recognize it on the statement | Confirms the payables contact, names the branch and the date, asks for the PO number, offers a payment link |
Delivered order to a contractor's shop or job site | Small to mid | Delivered to site, receiving slip never reached the office | Confirms the delivery was received, asks for a payment date, routes delivery questions to the branch |
Job account or project package | Large | Contractor waiting on the builder, owner or general contractor | Confirms the job and the payer, asks when the upstream payment is expected, logs the date and calls back on it |
Special order or equipment invoice | Mid to large | Wrong model questioned after delivery, start-up or warranty paperwork pending | Logs the objection and hands it to the branch or inside sales person who quoted it |
Short paid statement or open return | Small | Return not yet credited, price differs from the quote, ticket not recognized | Asks why the balance was left open, captures the reason, routes it to returns, pricing or the branch |
Counter and delivery rows hold the count, job account and equipment rows hold the dollars, and short pays are where margin leaks.
How Does Autonomous Follow-Up Work on Contractor Charge Accounts?
An autonomous agent does the follow-up itself. Kate calls the contractor's office manager or payables contact, says she is calling on behalf of your supply house, confirms the open invoices on the account, answers routine questions such as "which branch was that" or "who signed for this ticket", 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 contractor account might look like this, and it can start earlier or run more often for the accounts that need it:
Day 1 overdue: a friendly email with the open invoices, the branch, any PO numbers and a payment link.
Day 7: a text message or email to the office contact, listing every open ticket on the account.
Day 14: a polite phone call to walk through the statement 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 return question, a pricing dispute or a request to speak with someone goes straight to your team.
Job accounts run on their own track: Kate names the job, asks when the contractor expects to be paid on it, and follows up on that date. Credit decisions stay with your credit manager.
How Do You Handle Returns, Pricing Disputes and Unrecognized Tickets?
Three situations cause most of the friction for supply houses.
"We brought that back." An open return is the most common reason a contractor short pays. The follow-up should log the reply, note which branch took the return, and send it to whoever processes credits, rather than calling again about the same ticket. Our guide to customer deductions and short payments covers how to track these so they stop repeating.
"That is not the price we were quoted." Pricing disputes belong to the sales person who wrote the quote. Software should capture the ticket, the expected price and the quote reference, and route it to that person.
"Nobody here bought that." An unrecognized counter ticket usually means a helper signed for it. The useful step is to name the date, branch and signer, and ask the office to check with the crew. If it is still disputed, a person on your team decides.
What About Teams With Three or More People in Collections?
Larger supply houses usually have a central credit department supporting many branches. It spends its week on the biggest contractor and builder accounts, job account reviews and returns research, and small trade accounts wait for the next statement.
An AI agent changes the split. Kate covers every overdue account on a weekly cadence, small contractors included, and your credit team spends its time on the work that needs judgment: credit limits, holds, job account reviews, pricing disputes and key builder relationships. The team does not get smaller. Its coverage gets complete.
What About QuickBooks, NetSuite and the Rest of Your Stack?
Most supply houses run counter sales, pricing and statements in a distribution ERP. 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 ERP. Details are on the product page.
What Results Should a Supply House Expect?
Results depend on how old your overdue invoices are, how much of the ledger sits in job accounts, and how many contractor accounts have a working office 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 supply house, but it shared the pattern that matters here: a high count of small invoices to trade and business customers, alongside a few large balances. 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 account type. Counter and small contractor accounts should fall first.
Job account balances past their expected payment date. Each one tied to a named job and a logged date.
Open returns and short pays by reason, so branches can fix the cause.
PO capture at the counter.
Promises kept. Of the contractors who gave a payment date, how many paid by it.
Practical Takeaways for Supply Houses
Count open tickets, not problem accounts. A busy counter creates more invoices than a credit desk can chase.
Ask for a PO or job name at the counter, every time.
Keep job accounts visible on their own, with the job named in every follow-up.
Credit returns quickly so the statement matches what the contractor believes.
Ask any vendor how it handles counter volume and job accounts, and ask to hear real calls.

How can a supply house get paid faster?
Capture a PO or job name on every counter ticket, invoice the day material leaves the branch, credit returns promptly, send invoices to the contractor's office rather than the person who signed, include a payment link, and follow up on every overdue invoice every week. Abivo automates that follow-up so it happens even in peak season.
Does it work for electrical wholesalers and HVAC distributors with many branches?
Yes. Kate follows up on every overdue account across branches, and each dispute goes to the branch or person who owns that customer.
Can it follow up on contractor job accounts?
Yes. Kate names the job in every message, asks when the contractor expects to be paid on it, and logs the date so your team can see where each job account stands.
Is collections software the same as accounts receivable software?
Collections software is the part of accounts receivable software that gets overdue invoices paid. Abivo focuses on that part and connects to the accounting system that handles the rest.
