Travel, per diem and cross-border payroll costed to the job that caused them
Your crew left Spokane at five for a job past Colville, and the truck, the fuel, the per diem and the lodging all went to overhead because there was nowhere else to put them. Next week half of them are in Post Falls, which means Idaho income tax withholding on hours Washington never asks about. Construction accounting in Spokane has to handle distance: mobilisation and travel costed to the job that caused them, payroll split by the state where the work happened, and sales tax at the job site rate across a dozen small Eastern Washington jurisdictions.
On the ground
Downtown Spokane, Washington
Spokane serves a rural catchment that reaches across Eastern Washington, North Idaho and into western Montana, so the jobs are spread out and the crews travel. That turns two ordinary things, getting there and crossing a state line, into accounting problems a generalist bookkeeper has no reason to have solved before.
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.
A job two hours out costs more than the same job in the Valley, and if travel sits in overhead your cost report cannot say by how much. We build job costing for Spokane contractors that puts windshield time, fuel, per diem, lodging and the equipment move onto the project that incurred them, so the far jobs stop being subsidised by the near ones.
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.

Washington has no income tax and Idaho does, so the state line is a live payroll issue for any Spokane contractor taking work around Post Falls, Coeur d'Alene or Sandpoint. We set payroll up so the work state travels with the hours from the timecard onward, which is the only way withholding, unemployment reporting and job cost all end up right.
Working a wide territory means working a lot of taxing districts. Washington sources construction to the job site, Idaho reverses who pays the tax entirely, and material bought in one state and used in the other creates an accrual nobody makes on their own. Our construction tax planning reads the contract and the map, not just the ledger.
Public work around Spokane comes from the county, the city, the school districts, WSDOT and the airport, and all of it holds money back. We produce a monthly work in progress schedule on percentage of completion and keep retainage as its own tracked balance rather than letting it hide inside receivables where nobody is chasing it.
Spokane builds hard for seven or eight months and then the ground freezes, so the year is really one production window and one cash window and they do not overlap. Our controller services and CFO services answer the questions that season creates: what crew you can carry, what a distant job actually returns, and when the line of credit gets drawn.
A general bookkeeper can record transactions. Construction accounting is a different job.

Spokane is the service center for a region far larger than the city itself. In town there is a substantial hospital and medical education cluster, Gonzaga and the Washington State University health sciences campus in the University District, aerospace and metals manufacturing, warehouse and distribution space stretching along the I-90 corridor, and a downtown and Riverfront Park that have been steadily rebuilt. Housing keeps growing as people leave the west side for a lower cost of living. That is a healthy local pipeline, and it is also only part of the work a Spokane contractor actually takes.
The rest of it is out of town. Food processing and agricultural facilities in the Palouse, mining-adjacent work in the Silver Valley, school and municipal jobs in Colville, Deer Park, Cheney and Pullman, and a steady flow of work over the line into Post Falls, Coeur d'Alene and Sandpoint. Spokane contractors travel because the catchment is rural and there is not always a local trade capable of the scope. A three hour round trip is a normal Tuesday here, which is simply not true of a contractor working inside the Puget Sound corridor.
Distance is where the money leaks. Fuel, crew truck hours, motel nights, per diem, and moving a machine on a lowboy are all real costs of a specific project, but they are the easiest costs in construction to dump into overhead because they do not arrive with a job number on them. Once they are in overhead, a blended rate spreads them across everything, and the job forty miles out looks as profitable as the one down the street. Contractors here usually know intuitively that some work is not paying, and they cannot prove which. Our guide to job costing in construction covers the mechanics, but the first move is simply giving travel somewhere to go.
Then there is the border, forty minutes east. Idaho has a state income tax and Washington does not, so the moment a crew works over there you have withholding, unemployment reporting and possibly workers compensation questions that a Washington-only payroll setup will never raise on its own. Add a short season that freezes shut in November and retainage that arrives long after the work did, and the year has a predictable cash shape that most Spokane contractors are managing by feel. It is measurable months ahead if the books are actually built for it, and you can see how that has played out for other contractors in our construction accounting case studies.
Per diem, lodging and mileage paid to a crew working away from home are deductible business costs, but only if the reimbursement runs through an accountable plan with time, place and business purpose substantiated, and the meals portion of per diem is subject to the usual limit on deducting business meals. Contractors who reimburse casually and code it to overhead lose the job-level visibility and weaken the documentation at the same time. Some Washington prevailing wage determinations also carry travel and subsistence provisions on top of the base rate, which have to be paid and reported, not absorbed.
Idaho imposes a state income tax and Washington does not, so a Spokane employer whose crews work in Idaho generally has to register with the Idaho State Tax Commission and withhold on the wages earned for work physically performed there. There is no reciprocity that makes this go away. The practical difficulty is that nothing in a Washington payroll file prompts the question, so the obligation is usually discovered late. Recording the work state on the timecard alongside the job and the hours is what makes correct withholding possible at all.
Unemployment insurance wages for a worker are reported to one state, not apportioned, and the state is determined by a defined sequence: where the work is localised, then the base of operations, then the place of direction and control, then where the worker lives. Workers compensation is a separate question and a sharper one, because Washington is a monopolistic state where coverage comes from the Labor and Industries fund and is priced per hour by risk class, while Idaho uses a private insurance market. Coverage for Idaho hours has to be confirmed rather than assumed.
Washington sources construction to where the work is performed, so the correct combined rate follows the job site and the Department of Revenue location code that goes with it. A contractor working out of Spokane can bill jobs in the City of Spokane, Spokane Valley, Liberty Lake, Airway Heights, Cheney, Millwood, Deer Park and unincorporated county inside a single month, each at its own rate. Idaho then inverts the model: a contractor improving real property there is generally the consumer of the materials, paying tax on purchase rather than charging tax on the contract.
Washington public works require prevailing wage rates set by Labor and Industries for the trade and county, a Statement of Intent to Pay Prevailing Wages approved before payment, certified payroll records, and an Affidavit of Wages Paid before final payment and retainage release. Spokane County has its own wage determination. Separately, federally funded work including construction at Fairchild Air Force Base falls under Davis-Bacon with federal wage determinations and weekly certified payroll on a different system entirely. Contractors who run both need one payroll process feeding two compliance regimes.
Washington requires contractors to register with the Department of Labor and Industries as a general or specialty contractor, carrying a surety bond and general liability coverage at statutory minimums, with electricians and plumbers licensed separately. Idaho maintains its own contractor registration requirement, so working across the line is not covered by your Washington registration. Registration fees, bond premiums and insurance for two jurisdictions are overhead costs that belong in your burden and your bid rather than in a miscellaneous expense account nobody reads.
Washington lien law under RCW 60.04 sets a short window to record a claim after you last furnish labor or materials, with an earlier notice requirement for parties who have no direct contract with the owner, and Idaho runs its own separate deadlines that are not the same. A contractor working both sides is running two calendars. We are not attorneys and we do not file notices. What we do is keep unpaid amounts organized by job, tier, state and date furnished so the deadlines run off real data and your attorney has the backup immediately.
We support contractors across the Inland Northwest, from site work and paving crews chasing a short season to mechanical and electrical shops running hospital and campus buildouts in town.
Running a Construction Company in Spokane?
Get Your Free AuditA fair question if you already have a bookkeeper in town and a CPA who does the return. Here is the honest answer.
Most Spokane contractors do not need new software. They need what they already pay for set up so the field can record the job, the work state and the cost code once, from a truck, without anyone in the office retyping it three days later.
Most QuickBooks files we inherit were configured for a business that sells products off a shelf. For a contractor working a wide territory that means no travel cost codes, one sales tax rate applied to every job regardless of where it was, payroll that cannot tell a Washington hour from an Idaho one, and retainage hiding inside receivables.
Is your QuickBooks file working against you?
When the crew is ninety miles away, a paper timecard that reaches the office on Friday is already too late to be accurate. We connect field and time tracking to the accounting so hours arrive carrying the job, the cost code, the risk class and the state they were worked in.
Entered once, in the field, already carrying the job and the state.
Once the systems are connected, reporting stops being a history lesson. These are the reports Inland Northwest contractors use to decide what to chase and what to leave alone:
If the day-to-day recording is the problem first, start with construction bookkeeping for contractors and add the reporting once the file can be trusted.
Generally yes, and this is the single most common miss we find in Spokane books. Idaho imposes a state income tax and Washington does not, so a Washington employer sending crews across the line picks up an Idaho withholding obligation on the wages earned for work physically performed in Idaho. That means registering with the Idaho State Tax Commission, withholding on those hours, and filing Idaho returns. Because Washington has no income tax at all, nothing in a Washington-only payroll setup ever prompts the question, and contractors often discover it years later with penalties attached. The fix is structural: the timecard has to record the work state alongside the job and the hours.
Travel belongs on the job that caused it, not in overhead. A Spokane contractor routinely runs crews to Colville, Pullman, Moses Lake or Sandpoint, and the fuel, the truck hours, the motel nights, the per diem and the lowboy move for a piece of equipment are all real costs of that specific project. Dumped into general overhead they disappear into a blended rate, so the close jobs quietly subsidise the far ones and nobody can tell which is which. We set up travel and mobilisation cost codes, run per diem through an accountable plan so the substantiation exists, and put mileage and equipment transport against the project. Bidding accuracy on distant work improves immediately.
The rate follows the job site address, not your office or your yard. Washington sources construction to the place the work is performed, and the Department of Revenue publishes a location code for every taxing district. Around Spokane that means the City of Spokane, Spokane Valley, Liberty Lake, Airway Heights, Cheney, Medical Lake, Millwood, Deer Park and unincorporated Spokane County are separate rates a contractor can hit inside one week. Defaulting every invoice to one rate means under-collecting in some jurisdictions and over-collecting in others at the same time. We capture the site address and location code once, when the job is created, so every progress billing off it picks up the right rate.
The two states treat a contractor in opposite ways, which is why border work catches people out. On custom construction in Washington the contractor is making a retail sale, so sales tax applies to the whole contract price including labor, and you collect it from the customer. Idaho generally treats a contractor improving real property as the final consumer of the materials, so you pay tax on the materials you buy and you do not charge sales tax on the contract itself. Running Idaho jobs through a Washington billing template therefore charges tax that should not be there, and buying material untaxed in one state for use in the other creates a use tax accrual almost nobody records.
Yes. Public works in Washington fall under RCW 39.12, which requires payment of prevailing wage rates set by Labor and Industries for the trade and the county, a Statement of Intent to Pay Prevailing Wages approved before you can be paid, certified payroll records covering the work, and an Affidavit of Wages Paid approved before final payment. Spokane County rates are their own determination and are not the King County numbers. City of Spokane street and utility work, Spokane Public Schools bond projects, county work, WSDOT highway contracts and Spokane International Airport projects all sit inside this. Every one of those filings comes out of payroll data, which is why we treat it as an accounting job.
One state gets all of the wages for a given worker, and there is a defined order for deciding which. The multi-state test used by the Washington Employment Security Department and by Idaho looks first at where the work is localised, then at the base of operations, then at the place from which the work is directed and controlled, and finally at the state where the employee lives. It is not a split by hours. A Spokane framer who spends most of the year on Washington jobs and occasional weeks in Idaho is normally reported entirely to Washington. Getting this wrong creates duplicate reporting in one state and a gap in the other.
Not automatically, and this is a genuine exposure rather than a paperwork detail. Washington is a monopolistic state, so your industrial insurance comes from the Labor and Industries state fund and premiums are assessed per hour worked in each risk class. Idaho runs a private insurance market instead. A Spokane contractor taking work across the line needs to confirm that coverage extends to those hours before the crew arrives, and the answer depends on how long and how regularly they are over there. From an accounting standpoint the hours have to be tracked by state as well as by risk class so both the L&I quarterly report and any Idaho policy audit read off the same records.
Yes. Federally funded construction around Spokane, including work at Fairchild Air Force Base, brings Davis-Bacon prevailing wage rates and weekly certified payroll reporting that run on federal rather than state determinations. Contractors who are comfortable with the Washington intent and affidavit process are often surprised that a federal job needs a different wage determination, a different report and a different retention regime, and that the two systems do not talk to each other. We keep federal and state compliance work coming out of the same payroll run so the labor cost in your job report agrees with whatever was filed, on either system.
The Spokane building season is genuinely short. Frozen ground and snow shut down earthwork, paving and exterior trades for months, wildfire smoke can cost outdoor days in late summer, and the result is a compressed production window with revenue concentrated in the middle of the year. The cash problem is the lag behind it: costs are incurred through the season, retainage releases and slow closeouts land afterwards, and payroll for a crew you want to keep runs through a quarter with very little coming in. We forecast that gap by month rather than by year, so the decision about the winter line of credit, the equipment purchase or the crew you carry is made in September rather than in January.
