i run an HVAC and appliance repair service around Valencia and we have 6 technicians out in the field and generate around 45 to 50 work orders a day during peak season. up until now, we've been sending jobs to techs over WhatsApp and collecting paper service slips at the end of the day. but slips get lost, parts tracking slips through the cracks, and invoicing customers ends up taking up to three days, so the whole system has ground to a halt.
when I search online, I see a ton of free work order software. but every single one I look into either locks you out after 15 slips a month or doesnt let the tech capture photos and signatures on their phone in the field. is there a truly free solution that can handle 50 orders a day—either self-hosted on our own server or running in the browser—or are we inevitably going to have to switch to paid software?
