How Partial Payments Work

A partial payment is exactly what it sounds like: a customer pays part of what's owed on an invoice, and the remaining balance stays open until it's paid in full. It's common on larger jobs where a customer pays a deposit, then a progress amount, then a final balance — all against the same invoice.

The payment schedule is what makes it work

Rather than sending three separate invoices, one invoice can carry a built-in payment schedule: a deposit due at signing, a progress payment due partway through the job, and a final balance due at completion. The customer's payment page shows what's currently due, while still allowing them to pay the full remaining balance early if they'd rather.

Balance tracking has to be automatic

The moment a partial payment posts — through Stripe or recorded manually — the invoice's remaining balance, payment schedule status, and accounts receivable aging all need to reflect it immediately. Without that, it's easy to lose track of exactly how much is still outstanding on a partially paid invoice.

Partial payments vs. milestone invoicing

Partial payments on one invoice and milestone invoicing (separate invoices per phase) solve a similar problem in different ways. One invoice with a schedule is simpler to manage for jobs with a short timeline; separate milestone invoices make more sense when phases are weeks or months apart and each needs its own tracking and due date.

KinetiqBilling supports both — a single flexible invoice with a payment schedule, or fully separate milestone invoices generated from an accepted quote — so the billing structure can match how the job actually unfolds.
