Why contractors lose money on paperwork and how to stop it

Every experienced master knows what it looks like: end of the day at the construction site, pockets full of material receipts, photos in WhatsApp and a promise to yourself that you'll "input it tomorrow". Tomorrow becomes a week, a week becomes the end of the month — and suddenly you can't reconstruct where 800 euros went.

This is not an organizational problem. This is a system problem.

1. Unrecorded expense = direct loss

Imagine a typical scenario: a contractor buys screws, glue and profile in three different stores on the way to the site. Total 340 €. Receipts end up in the car, one is lost, two are transferred to the wrong client in the calculation. At the end of the job, no one charged that expense to the customer.

340 euros less. For one morning round.

Multiply that by 20 sites per year and you get a number that hurts.

2. Quotes in Word that no one can track

Classic problem: you send a quote from Word or hand-written on A4. The client calls you a week later with a question about item number 7. You look for which file you sent, what was the version, did you even get confirmation.

No history. No trace. No control.

3. Waiting for payment — because no one types the IBAN manually

"I'll pay as soon as I get home." — and then they forget. Or they type the wrong figure. Or laziness prevented them.

Every day of waiting for payment is a day in which you finance the client from your own pocket.

The solution to your problems is here

Exactly for this problem we developed Shark Business — a business tool that works in the field, without internet, without expensive SaaS and without data that is not yours.

Three things it solves immediately:

• AI receipt scanning — you photograph a receipt from the field, the system automatically recognizes the amount, VAT and supplier and enters it into your Google sheet. No more manual entry.
• QR code on every quote — every quote automatically generates a HUB3 barcode. The client scans with a phone and pays directly from the banking app. No typing IBANs, no errors, no delays.
• Your data, your Google account — everything lives in your Google Sheets. No vendor lock-in, no "if you don't pay the subscription we delete everything".

Not for office workers. Built for the field.

Shark Business is a PWA app — you install it on your phone as a real app, it works without internet and synchronizes when you catch a signal. It's designed for people who are on site all day, not for those sitting at a desk.

Price? One-time 99 € for the START package. No monthly fees.
