How to grow your payments app with septic tank emptiers

By SendPay Business · 29 September 2026 · 2 min read

Wherever homes and businesses are not on the sewer, septic tanks and pit toilets need emptying every so often. Emptiers with vacuum trucks, sometimes called exhausters, serve homes, schools, hotels, farms and building sites. Jobs are booked by phone, often at short notice, and paid on the day, mostly in cash, and emptiers also pay fees at the treatment site. A payments app that takes a deposit when a job is booked, lets customers pay by phone when the truck is done and lets owners pay drivers and site fees can win these firms, and every customer who pays sees your app.

Talk to septic tank emptiers

Ask local septic tank emptiers:

How do customers book and pay for a job today?
How often does a customer not have the money ready when the truck arrives?
Do schools, hotels or estates book you regularly?
How do you pay drivers and dumping or treatment fees?

Take a deposit when a job is booked

Sending a payment link for a deposit when a job is booked confirms it and cuts wasted trips.

Get paid when the job is done

Letting customers pay by phone as soon as the tank is emptied means the driver carries no cash and moves on to the next job.

Grow through regular customers

Schools, hotels, estates and farms need emptying again and again. When they pay through your app each time, it becomes part of how they run.
