Create bids in minutes — AI calculates quantities and prices for you

You're a small contractor and your time is limited. Massoi reads the blueprints, calculates quantities, and produces a professional bid — you focus on building.

Do you recognize these problems?

A small contractor's daily life is hectic. Bid calculation shouldn't take all evening.

Creating a bid takes hours

You measure by hand, calculate in Excel, check for errors. Evening after evening goes by with no time for anything else.

Calculation errors eat your margin

One forgotten line item or wrong multiplier and the bid is too low. You win the contract but lose money.

Bids don't look professional

Excel-made bids vary in quality. The client receives an unclear spreadsheet PDF.

Massoi solves these for you

AI does the heavy lifting. You review and send.

Upload a blueprint — AI identifies structures and calculates square meters, linear meters, and quantities.

Select unit prices from the built-in price list or use your own prices.

Frequently asked questions about bid calculation

What is bid calculation?

Bid calculation is the process where a contractor estimates the costs of a construction project and prepares a bid for the client. It includes quantity takeoff (calculating material quantities from blueprints), pricing (materials, labor, subcontracting), and adding margin and risk reserves. Bid calculation is a construction company's most important process — its accuracy determines the profitability of the contract.

Reverse charge VAT in bid calculation — how does it work?

Reverse charge VAT means that the buyer of construction services (main contractor) remits the VAT on behalf of the seller (subcontractor). In practice, the subcontractor invoices without VAT and the main contractor handles the tax payment. Reverse charge VAT applies to construction services when the buyer is a business that sells construction services. In bid calculation, this means subcontractor bids are VAT 0% and tax is only added to the end customer's invoice.

How does AI speed up bid calculation?

AI automates the slowest phase of bid calculation: quantity takeoff. Traditionally, calculating material quantities from blueprints takes 4–8 hours per project. AI reads the blueprint, identifies structures, and calculates quantities in minutes. The estimator only needs to handle pricing and bid review.
