Job coding, exempt material splits, and a close that beats the billing cutoff
Nobody in Columbus warned you that a data center job would triple the paperwork. Every material invoice now has to be split, because the owner's exemption certificate covers what goes into the data center and nothing else, while your blades, fuel and rented equipment stay taxable. The general contractor wants the pay application, the lien waivers and the subcontractor compliance packet on the same date every month, and missing it costs you thirty days of cash. At that point the books stop being a monthly chore and become the thing that gets you paid. We code it the week it lands.
On the ground
Downtown Columbus, Ohio from the Scioto Mile
A general bookkeeper can categorize a bank feed. What they cannot do is answer the questions a central Ohio contractor faces on every invoice: which job is this, is this material exempt on that job, and does paying this bill start or stop a statutory clock.
They didn’t just record transactions and call it a day. They built a custom chart of accounts around how a remodeling company actually runs, did a full catch-up on years of bookkeeping inside QuickBooks Online, and now stay on top of my monthly bookkeeping and payroll. Every step, they broke it down in simple terms instead of burying me in accountant talk.
FinTruction rebuilt the whole thing from the ground up, with real job costing, work in progress, and retainage. They didn’t just hand me reports and disappear; they walked me through my numbers until I understood them.
Sahil and his team handle the bookkeeping and job costing for my painting business. They cleaned up my books and set up integrations that give me accurate, timely job costing with solid weekly data. Reliable, detailed, and genuinely invested in getting the numbers right.
FinTruction is the only bookkeeping team we’ve found that truly understands construction accounting and WIP reporting. They aligned our income and costs across 21 jobs and gave us full, monthly transparency. Fast, accurate, and an indispensable partner.
When I came to FinTruction I had no financial structure. No job costing, no WIP tracking, books behind. They did a full cleanup and rebuilt job costing and WIP tracking in QuickBooks. Now I know what’s billed, what’s owed, and where every job stands.
A couple of minutes from a contractor we support, sharing what working with FinTruction has been like and what changed once their numbers finally made sense.
On a central Ohio campus job the sales tax decision happens at the supplier, hundreds of times a month, and it is not the same decision on every job. We record the exemption position against the job when it opens, then apply it at the bill so the exempt share, the taxable share and the accrual are all right the first time.
Every construction platform claims to have a "QuickBooks integration." Most break the moment your books need to be accurate. Sales tax mismaps, retainage disappears, change orders create duplicates, and job costing reports stop matching project reality. We fix the integration so your software, your books, and your job‑level numbers all tell the same story.

Campus owners and their general contractors pay on a calendar, and the calendar does not move for you. We treat the billing package as a process with a due date rather than a document somebody produces on the last afternoon, so the pay application goes in complete and the money arrives in the cycle you planned for.
Enrolled work on a controlled insurance program carries a different burden rate from your private work, and in Ohio the workers compensation piece never joins the wrap. We keep the payroll records that both the state fund and the program administrator expect, and make sure they reconcile to the labor sitting in job cost.
Ohio gives your subcontractors a statutory right to be paid quickly once you have been paid, with interest attached if you are late. That turns accounts payable into a dated process rather than a pile. We record when money arrived, what it covered, and when it went back out, so the ten day clock is something you manage rather than something you argue about.
If you are months behind, this is where we start. We rebuild from the last month that genuinely reconciles, put the tax treatment and the job coding right as we go, and then hold the file on a fixed cycle so a request from a general contractor, a surety or your CPA is a download instead of a week of archaeology.
A general bookkeeper can record transactions. Construction accounting is a different job.

Central Ohio did not just get busier, it changed shape. Licking County now holds more hyperscale data center campuses than anywhere else in the state, with Google, Meta, Amazon, QTS and Microsoft sites operating or under construction around New Albany, Johnstown, Heath and Hebron, and Amazon Web Services alone has committed billions of dollars across the region. Intel, the project everyone planned around, has pushed its New Albany fabs toward the end of the decade with the first module targeted for completion around 2030. A lot of Columbus contractors staffed for one curve and are being paid by a different one.
The financial consequence is that a two-truck company can find itself working as somebody's tier-two subcontractor on a campus with an owner big enough to have its own tax agreement with the state. That is a different administrative animal from a strip mall build-out. The billing runs on a fixed monthly cycle with a continuation sheet, waivers up and down the tier and insurance certificates that expire at the worst possible moment. The materials may be exempt from Ohio sales tax, partly exempt, or not exempt at all depending on the owner's agreement. And your consumables are taxable either way.
None of that is hard once. It is hard four hundred times a month, next to a residential remodel in Clintonville and a tenant fit-out downtown that follow completely different rules. That is where books slip. The office that could keep up when everything was a lump sum private job cannot keep up when half the invoices need a tax decision, a job code and a waiver attached to them before anyone is paid.
Meanwhile the steady work continues underneath the headlines. Ohio State keeps a construction program running more or less permanently, the hospital systems keep expanding, and Franklin County suburbs keep adding schools, roads and housing. That mix is healthy, but it means one company is running exempt campus work, prevailing wage public work and ordinary private work at the same time. We do the catch-up, fix the coding so those three streams never touch, and hold the file current. You can see the same approach applied elsewhere in our construction accounting case studies.
Ohio Revised Code 122.175 allows an agreement that exempts computer data center equipment from sales and use tax, and the administrative rule defining that equipment reaches building and construction materials sold to construction contractors for incorporation into the data center, including things that would otherwise be treated as business fixtures. It expressly does not reach tools and equipment consumed by the contractor. The exemption is claimed with a construction contract exemption certificate, form STEC CC. The contractee signs it, one certificate can go to the prime, the prime supplies copies to its subcontractors, and each contractor or subcontractor signs the copy it hands to its own vendors while retaining a copy in its records. Everything in that sentence is a bookkeeping obligation, because the file is what proves the purchase was properly exempt.
Under the same statute the Ohio Tax Credit Authority may exempt data center equipment completely or partially, with the percentage and the term written into the individual agreement, and eligibility rests on a capital investment of at least 100 million dollars at the site over three consecutive calendar years plus annual compensation of at least 1.5 million dollars at the site. Practically, that means the campus you are on this year and the campus you are on next year may not carry the same rate, and where the exemption is partial you owe tax on the balance of the incorporated material. That calculation is only reliable if the exemption percentage lives on the job record and the entry process uses it.
When an upper tier receives payment covering a lower tier's work, it generally has ten days to pay that subcontractor or material supplier, and interest accrues at 18 percent per year from the eleventh day absent a valid defense, with attorney fees possible if a claim is pursued. It cascades, so the same rule governs what you owe your subs and what your general contractor owes you. Neither side of that can be managed from memory. What makes it workable is capturing the date each payment was received and what it covered at the moment it lands, so the ten day window is visible in the payables queue rather than discovered in a demand letter.
Large central Ohio campuses often run a controlled insurance program, where the owner or the construction manager buys general liability and excess coverage for the enrolled work and you are expected to strip your own cost for that out of the bid, with the credit deducted from your contract value. That alone changes your burden rate on enrolled jobs. The part that catches out-of-state advice is workers compensation: Ohio is a monopolistic state, coverage is written by the Ohio Bureau of Workers Compensation rather than a private carrier, and it cannot be folded into a wrap. So enrolled payroll gets reported to the program administrator while the same payroll is still reported to BWC by manual classification, and the two have to agree when either one audits.
Franklin County work still includes schools, roads, county and municipal projects, and Ohio prevailing wage under Chapter 4115 is administered by the Ohio Department of Commerce. The thresholds for a public improvement are more than 250,000 dollars for new building construction and more than 75,000 dollars for reconstruction, alteration, repair, remodeling, renovation or painting, with lower road and bridge figures that are adjusted periodically. Above threshold the determined rate for the classification plus fringes applies and certified payroll goes to the public authority. The bookkeeping requirement is simply that the hours and classifications you file match the labor dollars sitting in job cost, because that is the comparison an audit makes first.
Ohio's Commercial Activity Tax is measured on taxable gross receipts rather than profit, and the annual exclusion is 6 million dollars for 2025 and later, with the annual minimum tax abolished and remaining taxpayers filing quarterly. One campus contract can move a Columbus contractor across that line in a single year while the margin stays exactly where it was, and progress payments, approved change orders and released retainage all count toward the measure. Keeping Ohio-sitused receipts identifiable in the file through the year is what turns that into a decision you make in June instead of a surprise you find in the spring.
We handle day-to-day books for contractors across Franklin, Licking and Delaware counties, from electrical and controls crews on a New Albany campus to remodelers working the older streets inside the outerbelt.

Most Columbus contractors do not need another platform. They need the file they already own configured so a material bill, a payroll run and a pay application each land in the right place the first time.
The files we inherit in central Ohio were almost always configured for a company that sells products. Jobs sit as customers, cost codes do not exist, every material supplier is coded to one expense account whether the job was exempt or not, and retainage is buried inside receivables. We rebuild it, then keep it that way.
Is your QuickBooks file the reason nobody trusts the numbers?
If your project managers already log commitments, time and change orders in a construction platform, the office should not be typing it again. We connect the field system to the accounting file so entry happens once and the two sides agree at close.
One set of numbers the field and the office both believe.
Clean coding is not the point by itself. The point is a short list of reports you can run a Columbus construction company on, delivered on the same date every month:
When you want work in progress schedules and bonding-ready statements built on top of these books, that is our construction accounting service for Columbus contractors.
Possibly not, but only if the paperwork exists before you buy. Ohio can exempt an eligible computer data center under Revised Code 122.175, and the rule that defines qualifying equipment reaches building and construction materials sold to construction contractors for incorporation into that data center, including items that would otherwise be treated as business fixtures. The exemption is claimed with a construction contract exemption certificate, form STEC CC. The owner signs it, the prime passes copies down, and each contractor and subcontractor signs its own copy for its own vendors and keeps it on file. No certificate at the counter means you paid the tax, and getting it refunded later is a project of its own.
Under Revised Code 122.175 the Ohio Tax Credit Authority may exempt data center equipment completely or partially, and the percentage and the term sit in the agreement with that specific owner. So one central Ohio campus may be fully exempt while the next one down the road is at a lower rate, and the taxable share of every incorporated material invoice has to be calculated and remitted. That is not a year-end adjustment. It is a coding rule that belongs on the vendor bill, with the exemption percentage recorded against the job so anyone entering an invoice applies the same number.
The exemption follows what goes into the data center, not what goes into your truck. The Ohio rule that defines computer data center equipment specifically excludes tools and equipment consumed by the contractor, so blades, bits, form lumber that does not stay, fuel, consumables and your rented equipment remain taxable purchases even on an exempt job. That single distinction is why exempt jobs produce more coding work rather than less. We set the cost codes up so consumables and rentals sort themselves away from incorporated material at entry instead of being untangled in a Department of Taxation review.
It usually is the fix. On the big central Ohio campuses the billing cycle is not negotiable: the schedule of values, the continuation sheet, conditional waivers from you, unconditional waivers covering the last payment, waivers from every one of your own subs, updated insurance certificates and, where public money is involved, certified payroll. Miss the window by a day and the money moves to the next cycle, which is thirty days of payroll you fund yourself. We work backward from the cutoff date, hold the compliance documents as a live checklist rather than a scramble, and have the billing ready before the deadline instead of on it.
It is. Ohio Revised Code 4113.61 requires an upper tier to pay a subcontractor or material supplier for work covered by a payment it received within ten days of receiving it, and interest runs at 18 percent per year from the eleventh day where there is no valid defense. Attorney fees can follow if it drags on. The obligation cascades down the tiers, so it applies to you as a payer and protects you as a payee. What makes it manageable is a record of the date each owner or GC payment actually landed and the date each sub was paid, captured when it happens rather than reconstructed from a bank feed months later.
Two things, and the second one catches Ohio contractors out. First, a controlled insurance program means the sponsor carries the general liability and excess coverage for enrolled work, so your bid is expected to exclude your own cost for that and the credit is deducted from your contract value. You have to be able to show the insurance cost you took out, which means the burden rate on that job differs from your other jobs. Second, workers compensation cannot ride the wrap here. Ohio is a monopolistic state, coverage comes from the Ohio Bureau of Workers Compensation, and a private program cannot write it. So you keep reporting payroll by manual classification to BWC while also reporting enrolled payroll to the wrap administrator, and the two sets of numbers have to agree.
Intel has moved its New Albany schedule out to the end of the decade, with the first module now targeted for completion around 2030. Plenty of contractors here staffed up for a curve that has flattened, while the data center campuses kept building. The bookkeeping answer is concentration reporting: backlog, receivables and retainage grouped by customer and by campus, refreshed monthly, so you can see what share of your money sits behind one owner. That is a five-minute report if the jobs are coded properly and an afternoon of guessing if they are not.
We start at the last month that genuinely reconciles and rebuild forward, because a compliance request is only as good as the underlying file. That means bank, card and line of credit activity brought current, transactions recoded to the correct job and cost code, exempt and taxable material purchases separated by job, retainage moved out of ordinary receivables, and subcontractor payments tied back to the waivers that were signed. Most contractors who are six to twelve months behind are current in three to five weeks. After that we hold the file on a fixed monthly cycle so a request for records is a download rather than a shutdown.
We keep the books for contractors across Franklin, Licking, Delaware, Fairfield, Union, Madison and Pickaway counties, including Columbus, New Albany, Dublin, Westerville, Hilliard, Grove City, Gahanna, Reynoldsburg, Powell, Johnstown, Heath, Newark, Pataskala and Lancaster. That spread matters here because the campus work and the neighborhood work are often the same crew in the same week. Our bookkeeping is fully remote, so you get construction-specific coding and a real monthly close without paying toward an office and without anyone driving to your trailer.
Start with the free Audit. Send access to your current file and your last set of statements and we will tell you what is miscoded, how far behind you actually are, and whether your exempt material purchases are documented well enough to survive a look. No charge and no obligation for that. Ongoing work is a flat monthly fee based on transaction volume, active jobs, payroll complexity and how much of your work runs under exemption certificates or a wrap-up program, so asking a question does not start a clock. Catch-up is quoted once and separately. Sahil Ahmad, CPA reviews the work.
