Ventilation quoting, costing and order management
In productionFrom sheet-metal development to the quote, on one platform.
A multi-tenant platform for ventilation manufacturers that calculates sheet development and cost for 25 part types, lets the customer enter the dimensions themselves, and produces a branded PDF quote that can be pushed to Paraşüt.
How it works today
Quotes are rebuilt in Excel every time. Sheet development, waste allowance, labour and margin change with whoever prepares the quote, so the same job can end up with two different prices. The customer describes the dimensions over the phone; when they are written down wrong, the manufacturing error comes back as cost. The quote PDF is formatted by hand, and the invoice is issued in a completely different program.
What the product does
A calculation engine that goes from a part's geometry to its sheet development, cut area, waste and weight, then through flange, gasket, bolts, insulation, paint and labour to the total cost. The customer enters their own dimensions on a company-specific address, the request lands in the dashboard, and the quote lines are adjusted and issued as a PDF on your letterhead.
How it differs from running on Excel
This product's competitor is not other software — it is the spreadsheets on the workshop desk. Here is exactly where they differ:
| On Excel, by hand | With HVAC Pro Suite | |
|---|---|---|
| Sheet development | A separate formula per part; it breaks as the file is copied, and nobody knows who added which allowance. | 25 part types inside the product; seam, elbow gore and damper allowances are named constants, tested in every release. |
| Price consistency | Whoever prepares the quote uses their own sheet, so the same job gets two different prices. | One material and labour list; the price comes out the same whoever prepares the quote. |
| Taking dimensions | The customer describes them on the phone, someone writes them down, and the error surfaces in production. | The customer enters the dimensions themselves, guided by the part's photograph and markers, and it stays on record. |
| Quote output | A document formatted by hand every time. | A branded PDF: logo, tax identity, IBAN, VAT rate and validity date come through automatically. |
| Getting to the invoice | The quote lives in one place and the invoice in a different program; lines get retyped. | An approved quote goes to Paraşüt as a sales offer in one click, with lines in m² and metres. |
| Finding past work | Version tracking by filename; finding last year's quote is a job in itself. | Every quote is stored, searchable by customer name and phone, and paginated. |
| Permissions | Anyone who opens the file can change the cost and the margin. | Material cost and profit rate stay with managers; staff run the daily work. |

Modules
Calculation engine
25 rectangular and round part types. For each part: sheet development (net area), cut area and waste, weight; then flange, gasket, bolts, insulation, paint and labour. Fabrication allowances such as seam width, elbow gore allowance and damper blade edge allowance are named constants inside the product, so they never quietly disappear from a quote.
HOW WE START
Four steps from a demo request to production use.
-
Demo request
Fill in the form or write to us directly. Tell us the size of your business and how you work today.
-
Live walkthrough
We show the product over a screen share, on data resembling yours. This is where the questions get asked.
-
Trial account
An account is opened for your business. You enter your own materials, prices and rooms and run one real job end to end.
-
Go live
If you decide to proceed, the account moves to the full version, your existing data is migrated and your users are set up.
Connections
What buyers ask before they decide.
Could my data get mixed up with another company's?
No. Every company's data is separated by its own identifier in the database; this isolation is verified by automated tests in every release.
Can I migrate my existing material and price lists?
Tabular material and price lists can be migrated. Show us the file you have and we will scope the migration together; this is not an automatic Excel import feature.
How many users can I add?
The trial account allows up to 2 users. On the Pro plan the number of users is not limited.
Do my company details and logo appear on the quote?
Yes. The quote PDF carries your logo, your tax identity and your IBAN.
What happens when the trial ends, is my data deleted?
Your account becomes inactive; your data is not deleted automatically. If you decide to continue, we move the account to the full version.
The part type I use is not on the list, can it be added?
If you need something beyond the 25 ready-made part types, we talk to you through our custom software line; that is a development request, not an automatic feature.
From sheet-metal development to the quote, on one platform.
Quote preparation gets faster, price inconsistency between quotes disappears, and responsibility for a wrong dimension becomes clear — the customer entered it themselves, and it is on record.
