INNERGY ERP vs. Homegrown Solutions
The spreadsheet was free.
The workflow isn't.
Excel, QuickBooks, CAD, MS Project, and email got your shop this far. We respect that. But a stack of disconnected workbooks can't tell you which jobs are making money while you can still do something about it. One connected system built for the trade can.
What "free" actually costs
The license came bundled with Office. The re-keying, the version chasing, and the margin you discover after the job ships did not. Here's what the research says about running a business on spreadsheets.
of working spreadsheets contain at least one error. Excel never flags a broken formula for you.
average cost of a single significant spreadsheet error: missed orders, expedited freight, blown margin.
per week the average operations employee spends finding and fixing spreadsheet errors. That time scales with your business.

A dozen disconnected tools, or one connected system
The homegrown stack isn't one tool. It's estimating workbooks, job-cost trackers, PO logs, and schedules glued to QuickBooks, CAD, and email, with your team as the integration layer. Here's how that compares, handoff by handoff.
Homegrown stack · Estimate to job
The winning estimate gets re-typed into the schedule, the PO log, and accounting. Every handoff is another chance for a defect.
INNERGY ERP
The estimate flows into the job, the schedule, purchasing, and the floor. No export, no re-import, no reconciling.
Homegrown stack · Job costing
Actuals aren't captured against the estimate, so margin problems surface after the job ships. Too late to act.
INNERGY ERP
Real-time job costing shows actual vs. estimated margin per job and per work order while the job is still running.
Homegrown stack · Version control
Nobody is sure which copy is current, and two people can't safely work the same numbers.
INNERGY ERP
One source of truth. When something changes, everyone sees it, from the front office to the shop floor.
Homegrown stack · Visibility
RFIs, parked estimates, and unreleased POs live in inboxes and island workbooks. The office work that makes or loses your profit stays invisible.
INNERGY ERP
Office inventory is visible on one screen, so you can see where work is stuck and move the right job to the floor on time.
Homegrown stack · Scale
The spreadsheet stack that worked at $2M quietly bleeds time and margin at $6M. And it breaks entirely when the person who built it leaves.
INNERGY ERP
Your institutional knowledge lives in a system the whole team can see, built to grow from your first million to your next ten.
Woodworking isn't general. Your software shouldn't be either.
Spreadsheets and generic ERPs share the same flaw: they assume every job looks like the last one. Custom millwork doesn't work that way. Every project is a one-off blend of dimensions, finishes, materials, and timelines, and general tools choke on change orders and custom pricing.
INNERGY was built by people who have run shops, for the way the best shops actually operate: estimating, project management, scheduling, purchasing, shop floor, and job costing in one place.
Why profit hides upstream
In this business, profitability is made prior to the sawdust.
The money is won or lost upstream of the saw, in estimating, project management, and engineering. Homegrown stacks keep that office work invisible, so problems only show up once they reach the floor. INNERGY makes the upstream work visible while you can still act on it.
Straight from shops that made the switch
These teams ran on homegrown tools first. Here's what changed, in their words.
Case Study · Taber Company
From Word and Excel to $44M
Taber Company started on simple tools and hit the ceiling as it grew: job costing gaps, untracked materials, no forecasting. With INNERGY, Taber now tracks project profitability hourly and scaled to $44M with higher margins.
“I have no idea how we managed without INNERGY. It has transformed every aspect of our business.”
