The HVAC invoice app built for peak season.

In a heat wave you are running calls back to back. PayRiven lets you speak an invoice between jobs and send it in under 30 seconds — so a busy week does not turn into a pile of unbilled work.

Speak it between calls

You say: “Invoice Delgado Residence — AC diagnostic $89, replaced dual run capacitor $145, 2 hours labor at $110, due on receipt” — PayRiven turns that into a finished, sendable invoice.

Made for how HVAC work actually gets billed

• Diagnostic, parts and labor on separate lines

  The three things every HVAC invoice gets questioned on are itemized clearly, which cuts down on billing disputes before they start.

• Keep up during peak season

  When you are running eight calls a day, a 30-second invoice is the difference between billing the same day and billing whenever the season slows down.

• Auto-Chaser follows up for you

  Reminders go out automatically at Day+1, Day+5 and Day+14 past due, so slow payers get chased without you scheduling it.

• Optional 1.5% late fee

  Apply a 1.5% late fee to overdue invoices automatically, so it is handled by the system rather than by an uncomfortable phone call. Enforceability depends on your contract and state law.

• Professional PDF with a payment link

  Homeowners can pay from the invoice itself instead of waiting until they are home with a checkbook.

• Encrypted and US-hosted

  Runs on US cloud infrastructure with enterprise-grade security, encrypted at rest and in transit.

Know what peak season is still owed

After forty calls in a fortnight, the question stops being what you billed and starts being what has actually landed. The Payment Reminders dashboard keeps outstanding, paid and overdue totals live, and puts an exact age on every invoice that has not been paid yet.

Snap the parts receipt, let the AI read it

Refrigerant, filters, capacitors and contactors add up fast across a season. Photograph the receipt — JPG, PNG or WEBP — and the AI pulls out the vendor, amount, tax rate, category and date automatically, so job costs stay accurate without you keying anything in between calls.

HVAC invoicing questions

• Can I bill a diagnostic fee and the repair on the same invoice?

  Yes. Say them both — for example "AC diagnostic $89, replaced dual run capacitor $145, 2 hours labor at $110" — and each becomes its own line item on the finished invoice.

• Does it handle maintenance agreements as well as one-off repairs?

  You can invoice any job you can describe out loud, including recurring maintenance visits. Each invoice is created from what you say, so the format follows the job rather than forcing you into a fixed template.

• How fast can I actually send an invoice?

  Under 30 seconds for a typical service call — speak the job, review what the AI produced, then send. The bottleneck is how long it takes you to describe the work, not how long the app takes.

• What happens when a customer does not pay on time?

  Auto-Chaser sends polite payment reminders automatically at Day+1, Day+5 and Day+14 after the invoice is due, with an optional 1.5% late fee.

• What does it cost?

  PayRiven is $9.99/month, or $79/year if you pay annually — about $6.58/month, saving roughly 34%. The 30-day free trial does not require a credit card, and all plans carry a 14-day money-back guarantee.

• How do I keep track of unpaid calls during a busy season?

  The Payment Reminders dashboard gives you a live view of outstanding, paid and overdue totals, and shows how many days past due each unpaid invoice is — or how long is left before it is due. Any invoice can be chased from that screen with pre-written reminder copy matched to its Auto-Chaser phase.

• Can PayRiven handle my parts receipts?

  Yes. Photograph a receipt or supplier invoice and upload it as a JPG, PNG or WEBP. The AI reads the vendor, amount, tax percentage, category and date off the image automatically, so expenses get captured without manual entry.
