Postcalc: Stop Guessing Whether Your Projects Made Money

Posted: 2026 | Category: Post-Calculation

The Question Nobody Can Answer

Ask any construction or carpentry boss a simple question: “Did the Vandenbroucke project make money?”

Watch what happens. A pause. A shrug. “I think so? The invoice was bigger than the materials.” Then a promise to “check the numbers later” - which means opening four different Excel exports, copying labor hours from one, material costs from another, and trying to remember how many hours the team actually spent on site.

Later never comes. The next project starts. The question stays unanswered.

Here is the uncomfortable truth: most project-based businesses don’t know which projects make money and which quietly bleed it. They know the company is profitable overall, because the bank account isn’t empty. But which jobs carried the others? Which client always costs more than they pay? Which type of work should they stop quoting altogether? Nobody knows. They’re flying blind on averages.

The Excel Graveyard

The data exists. That’s the frustrating part. It’s all sitting in exports from your business management software - OneTwo, Geodynamics, Exact Online - waiting to be connected.

But connecting it is brutal:

  • Labor hours live in one export, booked per worker per day
  • Material and purchase costs live in another
  • The sales total lives in your invoicing
  • None of them agree on project codes, date formats, or naming

So the post-calculation - the nacalculatie every accountant tells you to do - gets done for maybe the three biggest projects a year, by hand, weeks too late to change anything. For everything else, you guess.

Welcome to the Excel graveyard - where the answer to “are we profitable on this?” is buried under three incompatible spreadsheets nobody has time to reconcile.

How We Glued It Shut

Postcalc takes the Excel exports you already produce and turns them into a clear, per-project profit picture. No new data entry. No replacing your existing systems. You export, you upload, you see the truth.

Here’s how it works:

Step 1: Upload your exports. Drop in the Excel files from OneTwo, Geodynamics, or Exact Online. Labor, purchases, sales - whatever your system produces.

Step 2: Postcalc reconciles them. The platform parses every file, matches rows to the right project, and stitches labor, materials, and revenue together. It normalizes the mismatched project codes and date formats so the numbers finally line up.

Step 3: True margins appear. Every project gets a real profit-and-loss: revenue, labor cost, material cost, the actual margin in euros and in percent. Sorted worst to best, so the bleeders surface first.

Step 4: Anomalies get flagged. Postcalc watches for the things that quietly destroy margin - a worker booked 200 hours to a project that quoted 80, a purchase with no matching project, a job invoiced below its own cost. It surfaces them instead of letting them hide in the average.

Step 5: You decide with numbers. Which work to quote higher. Which clients to fire. Which crews are efficient. Which project types to stop taking. Real decisions, backed by your own data.

The post-calculation you kept meaning to do is now done for every project, automatically.

The Good Stuff

Reads What Your Systems Already Export

  • Native parsing for OneTwo, Geodynamics, and Exact Online exports
  • No integration project, no IT department, no replacing your tools
  • Drag, drop, done - works with the files you already generate

True Per-Project Profit

  • Real profit-and-loss for every single project, not just the big ones
  • Revenue, labor, purchases, and margin in euros and percent
  • Sorted by margin so the money-losers can’t hide
  • Drill into any project down to the individual labor booking

Labor Cost Where It Actually Went

  • Hours and cost broken down per worker, per project, per day
  • See which crews run efficient and which jobs always overrun
  • Compare quoted hours against actual hours, instantly

Anomaly and Data-Quality Detection

  • Flags projects invoiced below cost
  • Catches purchases and hours with no matching project
  • Surfaces booking errors before they poison your averages
  • Tells you when an export is incomplete instead of failing silently

Multi-Workspace by Design

  • Separate, isolated workspaces for each company or entity
  • Role-based access for owners, office staff, and bookkeepers
  • All your project history in one searchable place

Who This Unsticks

Carpentry and Interior Builders

You quote on experience and a gut feel for the hours. Postcalc tells you whether that gut feel is right:

  • See the real margin on every custom job, not a yearly average
  • Find out which type of work (kitchens? built-ins? shopfitting?) actually pays
  • Catch the projects where labor quietly doubled the quote
  • Quote the next one with real numbers behind you

Construction Companies

Multiple sites, multiple crews, costs landing from everywhere. Postcalc brings it together:

  • Per-site profitability the moment the exports are in
  • Labor productivity per crew and per project
  • Early warning on jobs heading underwater while you can still act

Owners Who Are Tired of Guessing

You don’t want another dashboard to babysit. You want one honest answer per project:

  • Did this make money? Yes or no, and by how much
  • No new data entry, no consultants, no six-month rollout
  • The nacalculatie you always meant to do, finally automatic

The Numbers

  • Minutes, not days to turn raw exports into per-project profit
  • Every project analyzed, not just the handful you have time for
  • 3 systems supported out of the box - OneTwo, Geodynamics, Exact Online
  • Zero new data entry - it uses the exports you already make

Built With De Laere Decor

Postcalc wasn’t dreamed up in a boardroom. It was built alongside De Laere Decor in Wevelgem - an interior-building and custom-furniture company with 40 years of total projects behind them, a workshop full of machinery, and the same problem every project-based business has: plenty of revenue, but no clear view of which projects actually carried it.

They had the data. It just lived in exports that never talked to each other. We built Postcalc to make those exports answer one question - did this project make money? - for every project, not just the big ones.

That’s the test for everything we build: does it work on a real workshop floor, for a real business, with the messy real-world data they actually have? Postcalc does.

What Makes This Different?

There is plenty of ERP software that promises post-calculation. It also promises a six-figure rollout, a year of implementation, and replacing every tool you own.

Postcalc is different because it starts from what you already have - the Excel exports your current systems already spit out. No migration. No rip-and-replace. No “let’s schedule a discovery workshop.”

  • No new data entry
  • No replacing OneTwo, Geodynamics, or Exact Online
  • No enterprise sales cycle
  • Just upload, reconcile, and finally see the truth

We built this because we watched a real company guess at its own profitability while sitting on all the data needed to know for sure. That was painful to watch. So we fixed it.

Get Started

Still telling yourself you’ll “check the numbers later”? Still finding out a project lost money months after you could have done anything about it?

Stop guessing.

Visit postcalc.glue.blue, upload last month’s exports, and watch your projects sort themselves from worst margin to best. The ones that surprise you are exactly the ones you needed to see.

Your projects already told you whether they made money. Postcalc just lets you read the answer.

Postcalc is built by glue.blue - we stick solutions to problems. Permanently.
