Invoice, get paid and reach every quarter with the numbers done
Typical situations, with sample data. These are not real clients.
- In the morning
You finish a job and invoice
Pick the client, add the lines, see the total live and issue. Gap-free numbering, fingerprint and QR included.
- Mid-morning
A fuel receipt arrives
Upload the photo from your phone. The reader extracts it and warns you if the tax ID or the amounts don't add up.
- In the afternoon
An invoice is still unpaid
In Collections you see what is overdue, due this week and this month. The reminder comes pre-written, ready to review and send.
- End of quarter
How much is due?
Pick the quarter and see the draft of model 303 and 130 with your data. You review it and download it to file it yourself.
