Metal fabricators often run two kinds of work under one roof: structural and miscellaneous steel jobs billed in progress against a contract, and job shop orders for manufacturers billed per PO when the parts ship. Collections software for metal fabricators follows up on both without pulling estimators and shop managers into collections.
Abivo is collections software for metal fabricators: its AI agent, Kate, follows up on overdue progress billing, change order and job shop invoices by phone, text message and email, straight from your accounting system, and hands any dispute, back charge or judgment call to a person on your team with the full history attached.
Best for: structural and miscellaneous steel fabricators, sheet metal and custom fabrication shops, and job shops that work for general contractors, erectors and manufacturers on net terms or progress billing, and have more open invoices than the office can follow up on each week.
Is This Also Accounts Receivable Software for Fab Shops and Steel Fabricators?
Yes, for the part of accounts receivable that gets invoices paid. Your ERP or job costing system handles estimates, jobs, material, invoicing and cash application. Abivo connects to the accounting system and handles the follow-up on every overdue invoice, the step most fab shops still do by hand. It works the same way for fab shops, steel fabricators, sheet metal shops, welding and fabrication companies and contract job shops.
Why Is A/R So Hard for Metal Fabricators?
Progress billing follows someone else's calendar. On construction work, you bill a portion of the contract each period through the general contractor's pay application process. If your billing misses the cutoff, or the schedule of values is questioned, the invoice waits a full cycle.
Change orders happen faster than paperwork. A connection is redesigned or extra embeds are added, the shop does the work to keep the job moving, and the change order is signed later. Until it is approved, AP will not pay it.
Back charges come off your payment. A general contractor or erector may deduct for field fixes, cleanup or delays they attribute to your crew or your steel. The deduction arrives as a short payment, often with little explanation.
Retainage waits for the end of the job. A portion of each progress payment is held until the project closes out, which can be long after your steel is installed.
Job shop work has its own friction. Manufacturers buying parts on a PO pay through procurement, match the invoice to the PO and receiving, and hold anything that does not match. A rejected part or quantity difference holds the invoice.
What Should Collections Software Do for a Metal Fabricator?
Separate project billing from job shop billing. A progress invoice to a general contractor needs a different conversation than a parts invoice to a manufacturer's AP team.
Name the job, the PO and the billing period in every message, so the customer knows exactly what the invoice covers.
Surface unapproved change orders early, so your project manager can get the signature while the work is still fresh.
Capture the reason for every back charge and short payment, and route it to the person who ran the job.
Keep retainage visible, so closed jobs do not leave money sitting in aging for months.
Sync with your accounting system and log every call, message and promise to pay.
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 |
|---|---|---|---|
Progress billing on a structural or miscellaneous steel job | Large | Missed pay application cutoff, schedule of values questioned, waiting on the owner | 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 | Change not yet approved, price questioned after the work was done | Names the job and the change order, hands pricing and scope disputes to your team |
Retainage | Mid to large | Project not closed out, punch list or paperwork still open | Asks what the customer still needs to release it, logs the answer, routes closeout items to the project lead |
Job shop production order on a PO | Small to mid, frequent | PO or receiving mismatch, rejected parts, sent to the wrong contact | Asks for the PO number, confirms the invoice was received and matched, routes quality questions to the shop |
Small repair, one-off or walk-in job | Small | Customer has no AP process, contact out of date | Steady polite contact by email, text and phone, with a payment link on every message |
Progress and retainage rows hold the dollars, job shop and small job rows hold the count, and change orders and back charges are where margin leaks.
How Does Autonomous Follow-Up Work on Project and Job Shop 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 job is 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 job shop account:
Day 1 overdue: a friendly email with the invoice, the PO number and a payment link.
Day 7: a text message or email to the payables contact, listing every open invoice on the account.
Day 14: a polite phone call to confirm the invoices were received and matched, 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 quality question, a back charge or a request to speak with someone goes straight to your team.
For progress billing, the cadence follows the pay application cycle. The first contact confirms the invoice made it into the current cycle, the follow-up tracks when the general contractor expects to pay, and anything about scope, back charges or retainage goes to the project manager.
How Do You Handle Change Orders, Back Charges and Rejected Parts?
Three situations cause most of the friction for metal fabricators.
"That change was never approved." Change order disputes belong to the project manager who agreed the work in the field. Software should capture the objection, the job and the change order reference, and hand it over at once.
"We back charged you for the field fix." A back charge is a deduction. The useful step is to log the amount the customer says it took and the reason, and route it to whoever ran the job, so your team can accept it or push back with the facts. Our guide to customer deductions and short payments covers how to track these so they stop repeating.
"Those parts were out of tolerance." On job shop work, a quality rejection holds the invoice. The claim belongs to your shop or quality lead. The software should log it, pass it on, and keep following up on any invoices the rejection does not affect.
What About Teams With Three or More People in Collections?
Larger fabricators usually have an AR team. It spends their week on pay applications, change order pricing and retainage for the biggest jobs, and the steady flow of small job shop and repair invoices waits.
An AI agent changes the split. Kate covers every overdue account on a weekly cadence, small accounts included, and your team spends its time on the work that needs judgment: pay applications, change orders, back charges, retainage and key general contractor and manufacturing relationships. The team does not get smaller. Its coverage gets complete.
What About QuickBooks, Sage Intacct and the Rest of Your Stack?
Many fabricators run estimating, job costing and shop scheduling in an ERP or construction accounting system. 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 Metal Fabricator Expect?
Results depend on how old your overdue invoices are, how much of the ledger is tied up in progress billing and retainage, and how many job shop 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 fabricator, but it shared the pattern that matters here: many smaller invoices to business customers alongside larger project work. 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. Job shop and small job invoices should fall first.
Unapproved change orders. How many invoices stall because the approval was never signed.
Back charges by reason. Field fixes, delays and cleanup, each counted, so you can fix the cause.
Retainage on closed jobs, with what the customer still needs to release it.
Promises kept. Of the customers who gave a payment date, how many paid by it.
