Job costing, WIP, and the exemption certificate your material tax turns on
In Missouri you are the final consumer of the materials you install, so sales tax on them is your cost, not the owner's. Inside Springfield city limits that is 8.1 percent on the material half of a job. On work for the health systems, Missouri State University or Springfield Public Schools it can be zero, but only if the exempt entity issues a project exemption certificate and you hold it before you buy. Miss that and you bid the job exempt and pay the tax anyway. We make the certificate part of opening the job, not a question at year end.
On the ground
Historic Commercial Street, Springfield, Missouri
This is the service most Missouri contractors do not know they are missing. Whether a job is exempt is decided by your customer and documented before you buy, which means it is an accounting task with a deadline, not a tax return question in March. Done at job setup it is one form and one file. Done later it is a claim you may not win.
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.

Work inside a running hospital or an occupied campus building costs differently from a greenfield job, and ordinary job costing swallows the difference. Containment, after-hours shifts, temporary partitions, staged handovers and access windows are all real money, and they are the first costs to vanish into overhead where nobody can price them next time.
Missouri public work runs on the Annual Wage Order, and since 2018 a job can sit on either a true prevailing wage or the public works contracting minimum wage depending on how many hours were reported for that trade in that county. Two crews on one site can land on two different mechanisms, and payroll has to know which is which every week.
Long institutional contracts are where underbillings hide, and an underbilling is money you have already spent and not yet asked for. We prepare a monthly work in progress schedule comparing cost to date against the current estimate, calculate earned revenue on percentage of completion, and show over and underbilling by job while there is still time to do something about it.
A Springfield contractor with two hospital systems, a university and a school district in the customer list has a concentration problem hiding inside a good year. Our controller services and CFO services cover what you can carry, what happens when one owner pauses a capital program, and whether your balance sheet supports the bond you want to chase.
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.
This market swings between customers who can buy materials tax free and customers who cannot, often in the same week. Generic bookkeeping records both the same way and the difference disappears into cost of goods.
Springfield is the third largest city in Missouri and the commercial center of the Ozarks, and its employment base has an unusual shape for a city this size. The two largest employers in the region are health systems, CoxHealth and Mercy. Behind them sit Springfield Public Schools, Missouri State University with more than 26,000 students, Ozarks Technical Community College, City Utilities, the City of Springfield and Greene County.
That matters to a contractor for one reason. Almost every one of those owners is capable of handing you a project exemption certificate, and almost none of the private work is. The other half of this economy is thoroughly taxable: Bass Pro Shops and O'Reilly Auto Parts are headquartered here, Prime is one of the country's larger refrigerated carriers, and the I-44 corridor keeps adding distribution space. So the same crew can pour a school addition on Monday and a warehouse slab on Thursday under completely different material tax treatment.
The failure mode is predictable. A contractor who mostly works private has an estimating template with material tax baked in and leaves it there on an exempt job, which quietly overstates the bid. A contractor who mostly works institutional assumes the exemption travels and buys taxed material for a private job without ever pricing it. Neither one finds out from the financial statements, because both errors land in the same cost of goods line and never move a percentage anyone looks at.
There is a second thing worth naming. When a handful of owners drive most of the capital spending in a metro, backlog concentrates. A hospital system pausing a construction program or a university pushing a project to the next fiscal year is a routine event for them and a serious one for you. That risk is only visible if your books can tell you what share of backlog and receivables sit with a single owner, which is a reporting question rather than a bookkeeping one.
A general bookkeeper can record transactions. Construction accounting is a different job.

You Are the Final Consumer of the Material: The Missouri Department of Revenue contractor rule at 12 CSR 10-112.010 treats a contractor as the final user and consumer of the materials and supplies used in fulfilling a construction contract. Where title passes only after the material is attached to the property, which is the normal case, the contractor is taxed on its purchase. So the tax is a cost of the job, not something you collect. The Missouri state rate is 4.225 percent, Greene County adds 1.75 percent and the City of Springfield adds 2.125 percent, giving a combined 8.1 percent inside city limits, with special districts higher again.
Project Exemption Certificates Under Section 144.062 RSMo: When an exempt entity contracts to construct, repair or remodel its facilities, that entity furnishes the contractor an exemption certificate authorizing purchases of materials for the project on a tax-exempt basis. The Department of Revenue publishes Form 5060 for the purpose. The certificate must carry the entity name and address, its Missouri tax identification number, an authorized signature, the project location and description, a unique project identification number and the project dates, including the date the contract was entered into, which is the earliest date materials may be purchased exempt for that project.
Where the Liability Actually Sits: Section 144.062 also provides that an entity which issues exemption certificates without the authority to do so is liable for the tax owed on the materials. That is worth knowing, but it is thin comfort in practice. If no certificate was ever issued, or the supplier billed you tax because you had nothing to show, the money has already left your job. The certificate is a document you chase before the first purchase order, not a defense you assemble later.
Prevailing Wage: Amended in 2018, Not Repealed: Missouri still has a prevailing wage law. House Bill 1729 took effect on August 28, 2018 and exempted public works with an accepted bid or estimated cost of 75,000 dollars or less, and it created two rate types above that threshold. Where 1,000 or more reportable hours were worked in an occupational title in the locality, the Annual Wage Order carries a prevailing wage. Where fewer hours were reported, the rate is the public works contracting minimum wage, set at 120 percent of the average hourly wage in the locality. The Division of Labor Standards issues an order each year, and Annual Wage Order No. 33 became final on May 29, 2026.
Mechanics Lien Timing: Section 429.080 RSMo gives six months from the date you last furnished labor or material to file, and that clock runs from your last work rather than from project completion. Everyone other than the original contractor must give the owner ten days notice before filing, and the original contractor has a separate duty under Section 429.012 to serve a statutory disclosure notice with the contract or first invoice before taking payment. We are not attorneys and we do not file notices. We keep unpaid amounts organized by job, tier and date furnished so the deadline calendar runs off real data.
Licensing Is Local, With One State Exception: Missouri has no statewide general contractor license, so the requirement is set by the city or county you are working in. Electrical contracting is the exception, with a statewide license available. In Springfield, Building Development Services runs contractor licensing and trade certification, and categories including electrical, mechanical, plumbing and gas fitting have to show bond or insurance before a license is issued. Fees, bonds and renewal dates belong in the accounting by jurisdiction, because a lapsed license in one city stops a job in that city only, and nobody notices until it does.
A fair question if you already have a bookkeeper or a CPA who files the return. Here is the honest answer.
Contractors who were behind, off the bank, or heading into an audit. Same work, different trades.
Built From Scratch
"FinTruction set the accounts up properly first, then cleaned up everything I never entered."
Rescue + Monthly
"They built a custom chart of accounts around how a remodeling company actually runs."
Most Springfield contractors do not need new software. They need what they already pay for configured for construction, so the tax position on a job and the true margin on it are both visible without a second system.
Most QuickBooks files we inherit were configured for a business that sells products. For a contractor that means jobs are customers, cost codes do not exist, retainage hides inside receivables, and there is nothing anywhere in the file recording whether a job was bought exempt or taxed.
Is your QuickBooks file working against you?
If your project managers already track budgets, commitments and change orders in a construction platform, the office should not be typing it in again. We connect the field system to the accounting so the numbers agree and the month does not open with an argument about whose figure is right.
One set of numbers that the field and the office both believe.
Once the systems are connected, reporting stops being a history lesson. These are the reports Springfield contractors use to decide what to chase and what to walk away from:

Yes, on most private work. Missouri treats a contractor as the final user and consumer of the materials it incorporates into real property, so the tax lands on your purchase rather than on the owner. Where title to the material passes only once it is attached to the building, which is the ordinary case, the Department of Revenue rule is that the contractor is taxed on its purchase. That is why the material line in a Springfield bid is not the supplier quote. It is the quote plus roughly eight percent, and a bid that forgets it is short before the first delivery.
It is the document that turns the tax off, and it comes from your customer, not from you. Under Section 144.062 RSMo, when an exempt entity contracts to construct, repair or remodel its facilities, that entity furnishes an exemption certificate authorizing purchases of materials for the project on a tax-exempt basis. The Missouri Department of Revenue publishes Form 5060 for this. The certificate has to carry the entity name and address, its Missouri tax identification number, an authorized signature, the project location and description, a unique project number and the project dates. You present it to your supplier to buy exempt.
The test is whether the customer holds a Missouri sales and use tax exemption letter, not whether it feels like a charity. In practice that covers a lot of this market: the City of Springfield, Greene County, City Utilities, Springfield Public Schools, Missouri State University and Ozarks Technical Community College, and the not-for-profit health systems. It does not cover a private developer, a franchise buildout, a landlord improving leased space or a homeowner. Ask for the certificate and the exemption letter at contract signing rather than assuming from the customer name.
In the awkward middle. The certificate states the date the contract was entered into, and that date is the earliest date materials may be bought for the project on a tax-exempt basis, so the contract date is the anchor rather than the day the paperwork showed up. The practical problem is different: a supplier will not sell you exempt without the certificate in hand, so those early invoices come through taxed, and unwinding them afterwards is slower and less certain than getting it right on day one. We treat the certificate as a job-opening step, alongside the insurance certificate.
Yes, and Form 5060 has a subcontractor section for exactly that. The certificate authorizes purchases for the project, and the general contractor extends it to the subs and suppliers buying material for that project. Two things go wrong here. The first is that nobody extends it, so your mechanical sub quietly pays tax on the equipment and bills it back to you inside a lump sum. The second is that a sub keeps using it after the project ends. We track which jobs carry a certificate, who it was extended to, and when it expires.
The Missouri state rate is 4.225 percent. Greene County adds 1.75 percent, and the City of Springfield adds 2.125 percent, which puts the combined rate inside city limits at 8.1 percent. Special districts push some addresses above that, and a job in Nixa, Ozark, Republic or Branson sits on a different combination again. This is why material tax cannot be a single percentage in your estimating template. We record the rate by delivery location inside job cost so the bid and the ledger use the same number.
Missouri still has a prevailing wage law, and it was amended rather than repealed. House Bill 1729 took effect on August 28, 2018 and set an exemption for public works with an accepted bid or estimated cost of 75,000 dollars or less. Above that, the Division of Labor Standards publishes an Annual Wage Order for each county and occupational title, and the current one, Annual Wage Order No. 33, became final on May 29, 2026. Rates change with each order, so you cannot carry last year numbers forward into this year bid.
It is the second rate type House Bill 1729 created, and it catches people out. If 1,000 or more reportable hours were worked in that occupational title in that locality, the wage order carries a true prevailing wage. If fewer than 1,000 hours were reported, the rate becomes the public works contracting minimum wage, set at 120 percent of the average hourly wage in the locality. Outside the two big metros that second case is common, so on a Greene County job two trades on the same site can sit on two different rate mechanisms. Read the wage order per title rather than per job.
The core deadline is six months from the date you last furnished labor or material, under Section 429.080 RSMo, and it runs from your last work rather than from project completion. Everyone other than the original contractor also has to give the owner ten days notice before filing. The original contractor has a separate obligation under Section 429.012 to serve a statutory disclosure notice with the contract or the first invoice, before taking payment. We are not attorneys and we do not file notices. We keep unpaid amounts organized by job and by date furnished so your attorney is not reconstructing the timeline.
