Plumbing contractors usually outgrow QuickBooks as soon as you need reporting to track more than a small team. If you cannot see what a job is costing during rough-in, or run a profit and loss by project, location, or item, that is the real signal it is time to look at Sage Intacct Construction.
We move plumbing contractors between these two systems. Brady Curtis, Tina Rehberg, and Troy Guevara explain what to compare, and what the move actually involves.
What QuickBooks does well—and where it falls short
QuickBooks is good at recording transactions. It can tell you which expense account received a check or invoice. Construction job costing requires more detail: which job incurred the cost, which cost code applies, and what type of cost it was.
The timing of that information determines how useful it is.
If a contractor cannot see job costs until the project is complete, or until someone builds a separate report, the accounting records may be accurate but the business insight arrives too late. The project manager can explain what happened but no longer has an opportunity to change it.
A construction accounting system should answer questions such as:
- How do actual costs compare with the budget today?
- What does project profitability look like right now?
- Is labor productivity tracking according to plan?
- Where should the team adjust before the next phase begins?
Sage Intacct Construction provides that job-level structure. Your team can review budgets and project profitability daily, then revise forecasts as the work changes. You know where the job stands at the end of each day rather than learning next week how last week went.
This visibility is especially important when managing labor.
I can build a school. I know how many brick it takes, I know how much concrete it's going to take. If something's out of whack on any of that, I get a change order, so I'm compensated. But I can't control my labor. I literally have to guess what it costs me to lay every brick and pour every yard of concrete. It's an educated guess, but it's a guess. If I can't control that number I'm going to lose money, and if I control that number I make money.
Troy Guevara · Construction TechnologistMaterials can often be tied to quantities, purchase orders, and change orders. Labor is less forgiving. Once your team has spent the hours, the project manager cannot get them back.
Why plumbing contractors outgrow bookkeeping systems
Plumbing contractors face a particular version of this problem because they remain involved throughout long stretches of a project.
Underground plumbing can begin soon after the footings are installed. Rough-in follows, while toilets, faucets, and other fixtures may not be installed until near the end of the project. Unlike a trade that completes one concentrated phase and leaves, a plumbing contractor can remain exposed to the project's performance for most of its schedule.
Mechanical, electrical, HVAC, and plumbing contractors face similar accounting and operational demands, even though the trades themselves are different.
Spending a long time on a job creates more opportunities for small problems to add up. A few extra labor hours during rough-in may not seem serious on their own. Repeated across crews, floors, and weeks, they can materially change project profitability.
They do their rough-in, and if they don't compare their numbers immediately they may not get that information until they're done with the rough-in, and then they're going 'oh crap, now we've got to catch up.'
Troy Guevara · Construction TechnologistAt that point, catching up may not be realistic. The team needs current project-level information while the phase is still underway.
Material risk also varies across plumbing work. Raw materials such as PVC carry less financial risk than fixtures, where cost and availability create real pressure. If material costs rise after the contract price has been set, labor is the only place left to make the job back. That is why current labor data matters.
Your accounting design should also reflect how the company earns revenue. A service-only plumber, a construction-only plumber, and a contractor running both sides of the business have different reporting needs. Make sure your implementation partner understands that operating model before discussing software features.
The reporting test for QuickBooks
Here is a practical test you can run this week: try to produce profit and loss statements by customer, location, project, and item.
I'd ask them to run a P&L by different dimensions (Customer, Location, Project, Item for example). It can't be done in QuickBooks because it doesn't have a dimensional chart of accounts.
Brady Curtis · ERP AdvisorThis structural difference separates bookkeeping from construction accounting.
In Sage Intacct Construction, each job is tracked as a dimension at the general ledger level. Transactions can also include dimensions such as location, cost code, cost type, project ID, customer, vendor, and item. These dimensions allow you to analyze the same transactions from different angles without forcing every reporting requirement into the chart of accounts.
Dimensions, again, are the core hurdle. In QuickBooks they understand customers and vendors — and those are dimensions in Intacct too — but the expansion is the new part: locations, cost codes, cost types, project IDs. A lot of QuickBooks clients don't use projects at all, so the shift we're guiding them through is going from seeing accounting only at the general-ledger level to seeing it at the project and cost-code/cost-type level.
Tina Rehberg · Senior Sage Intacct ConsultantDimensions matter because reporting requirements change over time. A bonding company may need one view, while a bank requests another. A new state requirement or private equity owner may require an entirely different format.
Without dimensional reporting, every new request can become another spreadsheet exercise. Someone exports the data, reorganizes it, checks the formulas, and repeats the process the following month.
With dimensions, your accounting system can present the same underlying transactions in the format each audience needs.
They don't have good reporting, they don't have real-time reporting. They need reporting for their bonding company, for their bank. They spend all this time building these reports. In Intacct I do it once, it's done.
Troy Guevara · Construction TechnologistSigns your plumbing company has outgrown QuickBooks
The clearest signs usually appear in your team's daily work before they show up in a revenue figure.
WIP reporting, retainage, and change orders are common examples. They are normal parts of construction, but they require more than recording that a job occurred and a payment arrived.
QuickBooks can often be stretched to support these needs. The question is what that stretch costs.
The annual software cost may be low, but hidden costs can accumulate in other areas:
- More time spent building and checking spreadsheets
- More year-end work for CPAs and outside accounting firms
- Manual data transfers between systems
- Repeated effort to produce consolidated or specialized reports
- Delays between project activity and management visibility
Other signs include:
Multiple legal entities. Separate QuickBooks files make it cumbersome to move between entities, and consolidated reporting often depends on Excel.
Growing transaction volume. As transaction volume increases, system performance can become an issue and teams may need to remove historical data.
More integration requirements. QuickBooks does not offer the same web services API for real-time integrations, so teams may become more dependent on manual imports.
A greater need for workflow and automation. Manual tasks become more difficult to manage as the company adds employees, entities, projects, and approval requirements.
Broader ERP requirements. As operations become more complex, contractors often add standalone applications or custom connections around QuickBooks.
QuickBooks has not failed in these situations. Your company is now asking the accounting system to do work it was not designed to handle.
What the move looks like for a plumbing contractor
Moving from QuickBooks to Sage Intacct Construction involves more than recreating the same setup in a larger system. Your company is moving from general-ledger-centered bookkeeping to a dimensional construction accounting model.
For that reason, the transition is usually more involved than a migration between two Sage products.
It's a much bigger jump. A Sage client already has the mindset and structure we need — multi-entity, dimension-based, organized around GL prefixes and sub-accounts. QuickBooks clients don't come in that way. Audra puts it well: Sage is the family, and each Sage product just speaks a slightly different dialect — Sage 100 to Sage 300 to Intacct is like the West Coast to the East Coast, a minor language barrier. QuickBooks is a different country. So when a QuickBooks client comes over, it takes more time and more training than a move inside the Sage family. Either way our team can adapt and migrate them properly — it's just a question of how much translation is involved.
Tina Rehberg · Senior Sage Intacct ConsultantYour implementation partner should learn how your company works today, understand how you track projects, and translate that operating model into dimensions, cost codes, cost types, projects, and reporting structures.
Inventory can add another layer of complexity for plumbing contractors. A company that tracks detailed item IDs and part numbers needs more planning than one that uses a broad cost-code structure.
Ackerman, a plumbing client, came over from QuickBooks. They were more complex than a typical Sage-to-Sage move because they brought in a lot of inventory with very strict inventory information — item IDs, part numbers, the works. Compare that to a client like Interstate Mechanical & Core, who was very general with cost-code structure and didn't carry all that item detail. So Ackerman took longer to implement, both because of the inventory complexity and because they were coming from QuickBooks rather than a Sage product. The lesson is that "QuickBooks migration" isn't one thing — inventory-heavy contractors carry extra structure that has to be modeled carefully on the way in.
Tina Rehberg · Senior Sage Intacct ConsultantThat is why your choice of implementation partner matters.
Look for a partner with specific Sage Intacct Construction experience, not just general Sage Intacct experience. The partner should also work regularly with construction companies. Sage Intacct Construction is designed around the financial and operational requirements of contractors, so construction knowledge is essential.
Sage Intacct's open API also supports integrations with third-party applications used in construction and the trades. Your field, estimating, and service applications can feed the accounting system instead of requiring someone to reenter the same information.
A good implementation should not reproduce every old process in a new system. Some processes should change. That is where much of the return comes from: eliminating duplicate entry, spreadsheet work, reporting delays, and other workarounds that accumulated while the company grew.
The deciding question: Can you see project profitability?
QuickBooks deserves credit for helping many plumbing contractors build their companies. Outgrowing it does not mean it was the wrong system when the company started. It means the business and its accounting needs have become more complex.
The deciding question is simple: Can you and your project team see project profitability while the job is still in progress?
If you cannot run a P&L by project, location, or item—or compare labor and fixture costs with the budget during rough-in—you have identified a visibility gap.
QuickBooks records what happened. Sage Intacct Construction gives your team current job information while there is still time to act.
