Recurring revenue shouldn't live in a separate billing app. If you charge a customer the same amount on a schedule — monthly maintenance, monitoring, lawn care, a service plan — Knockio runs that subscription inside the same system that already holds the lead, the accepted estimate, the invoices, and the payments. You set the schedule once, and Knockio creates a real invoice every billing cycle, ready to collect the same way you collect every other job. Nobody re-enters the customer, and nobody has to remember to send the bill.
Schedule a DemoSubscription billing software automates the repeating part of getting paid: instead of writing a new invoice every month, you create one subscription — the agreement and the billing schedule — and it generates an invoice on its own each cycle. In Knockio the subscription answers "how often do I bill this customer, and for how much," while each invoice it creates is a real invoice your team sends and collects like any other. A subscription can belong to a lead directly or come from an accepted estimate, and it keeps recurring charges cleanly separate from one-time work.
Create a subscription directly on a lead or from an accepted estimate
Create a subscription directly on a lead, like monthly roof maintenance for a homeowner, or spin one up from an estimate the customer already accepted — so recurring work becomes recurring billing without building a new record.
Create a subscription directly on a lead, like monthly roof maintenance for a homeowner, or spin one up from an estimate the customer already accepted — so recurring work becomes recurring billing without building a new record.
When a subscription comes from an estimate, Knockio pulls in only the recurring line items. A one-time install keeps its own normal invoice, so recurring and one-time charges never blur together.
Choose the products, price, billing frequency, and start date, plus an optional number of billing cycles or an end date, and Knockio handles every bill after that.
A new subscription starts as a draft, so it isn't charging anyone while you build it.
Confirm the products, prices, how often it bills, and when it starts before a single invoice goes out.
Activate it and Knockio starts billing on the date you choose.
When a billing date arrives, Knockio creates that period's invoice on its own — no one has to remember to send it.
Every invoice arrives ready to send and collect, moving through the same payment process as any other Knockio invoice.
Each invoice uses the subscription's pricing and bills the lead's current main contact. Change that contact later and only future invoices update — past invoices stay exactly as they were sent.
Pause billing for a seasonal gap or a customer vacation, with an optional reason, then resume and pick the next billing date when you're ready. The agreement stays intact.
If an invoice goes overdue the subscription pauses new billing until it's paid, then picks up right where it left off — so a customer can't quietly keep racking up bills, and you don't lose your place in the schedule.
Cancel any time and the invoices you've already sent stay collectible, or let a subscription finish on its own when it reaches the number of payments you set or its end date.

A subscription in Knockio isn't a billing tool bolted onto the side of your operation. It's tied to the same lead, estimate, invoice, and payment records your team already works, so recurring revenue runs on the pipeline you use for everything else — from a door-knocked customer to a paid monthly invoice, with nothing re-entered along the way.
Because the subscription lives on the lead or accepted estimate, the customer, the schedule, and every invoice sit on one record, so there's no separate billing app to reconcile and nothing to re-type.
When a subscription invoice goes overdue it moves to Past Due and pauses new billing, so an unpaid customer can't quietly keep stacking up invoices — and billing resumes right where it left off once they pay.
Pause a subscription through the off-season and resume it when work picks back up, so a seasonal customer stays on the books without being billed for months they aren't being served.
