HVAC software built around the work

Get from finished work to paid without breaking the workflow.

OtisOS connects invoicing and payment status to the customer and service record, with integrated Helcim processing for secure card checkout and lower-cost ACH options.

Built into OtisOS

One more part of the workflow, not another disconnected app.

Integrated checkout

Move from an OtisOS invoice into secure Helcim checkout while keeping the payment tied to the work.

Transparent pricing model

Helcim passes through interchange/network costs and adds a published processing margin rather than hiding everything inside one flat percentage.

Automatic volume discounts

Helcim reduces its published processing margin as rolling card volume reaches higher tiers.

ACH for larger invoices

Bank payments can provide a lower-cost option for high-dollar HVAC invoices. Current U.S. Helcim ACH pricing is 0.5% + 25¢ with a $6 cap for transactions under $25,000, subject to Helcim's terms.
