Job and invoice app for HVAC technicians
Every service call needs a record. Every replacement estimate needs to look professional. Logged keeps your job history per customer, works offline in attics with no signal, and sends estimates your customer accepts with one tap from their phone.
Why HVAC techs need a job log app
Seasonal callbacks need documentation
"I serviced this furnace 8 months ago — what did I do?" Without a job log you guess. Logged keeps every job per customer permanently — notes, photos, line items, the works. One tap shows you the full history of every visit.
Maintenance contracts need clean records
A residential service contract requires you to document each seasonal visit. Logged's job log with photos and signature on every visit gives you a clean paper trail — no chasing down paperwork or emailing yourself photos.
Big job estimates need to look professional
A $9,000 system replacement quote on a Word document loses to a clean PDF with photos of the existing equipment and clear line-item pricing. Logged's estimate is photo-embedded and sent as a web link the client reviews on their phone.
How Logged fits an HVAC tech's day
Full job history per customer, always on-device
Every job you create in Logged is stored locally and synced to the cloud. Tap any customer to see every service visit — notes, photos, what was replaced, what was billed, and whether it was paid. Works offline when you're pulling the record in an attic.
Photo capture → auto-attach to job → embed in PDF
Photograph the existing furnace, the filter, the refrigerant levels — one tap per photo. Every photo goes into the job record and embeds automatically in the invoice or estimate PDF. No extra steps.
Estimate link the customer accepts from their phone
Build the replacement estimate in Logged, tap Send. Your customer gets an email with a link — line items, photos of the current system, your pricing. They tap Accept and you get a push notification instantly.
