Questions plumbers ask us

Do plumbers charge sales tax on labor?

It depends on the state. In states like Texas and California, repair labor on real property is generally not taxable, but materials are. Influx Theory lets you tag lines as taxable or non-taxable individually.

How do I invoice for emergency call-outs?

Add a flat dispatch fee as a separate line item before labor hours. That makes the surcharge obvious to the customer and easier to defend if questioned.

Can I take payment in the truck?

Yes. Every Influx Theory invoice has a tap-to-pay link that opens on the customer's phone — they pay by card or Apple Pay before you leave the job.
