Invoices clients can pay in two taps

Most late payments are not refusals. They are friction. A PDF invoice asks the client to open an attachment, find their card, and use a payment method you specified in a footnote. A SupaBook invoice is a link they can pay on their phone, with no account required.

What is included

• Professional invoices: line items, tax, notes, and due dates.
• Card payments: clients pay by card with no account required, powered by Stripe.
• Payment schedules: deposit now, balance later, so you are not waiting until delivery to see money.
• Payment plans: monthly installments from 2 to 12 payments for larger projects.
• Pay-in-full discount: incentivise upfront payment when cash flow matters more than total.
• Live status: Sent, Partial, Paid, and Overdue, tracked automatically.
• Client record: full payment history stays attached to the client alongside calls, proposals, and projects.

Deposits and payment schedules

For project work, a single invoice at the end is the slowest way to get paid. SupaBook lets you split an invoice so a deposit is due now and the balance is due on a set date, with automatic due dates and payment tracking on both halves.

For larger engagements you can offer a payment plan of 2 to 12 installments, which often closes work that would otherwise stall on price.

Who it is for

Invoice software matters most for businesses billing project work rather than a flat monthly fee. That includes photographers and videographers billing shoots and licensing, designers and agencies billing project milestones, consultants billing retainers and one-off engagements, wedding and event vendors collecting deposits well before the date, contractors billing staged work, and any freelancer who has spent a week chasing an unpaid PDF.

If you are quoting before you bill, proposal software handles the front half and flows selections straight into the invoice.

Invoice software FAQs

How do clients pay?

Clients click the invoice link, review it, and pay by card. No account and no PDF or email chain required.

Can I take a deposit up front?

Yes. Payment schedules let you collect a deposit now and the balance later, each with its own due date and tracking.

Can I offer a payment plan?

Yes. Monthly payment plans support 2 to 12 installments, and you can offer a pay-in-full discount alongside them.

Do I need to set up a payment processor?

Card payments are accepted through Stripe, so you do not need to build your own processor integration.

How do I know if an invoice is overdue?

Every invoice carries a live status of Sent, Partial, Paid, or Overdue, and due dates are tracked automatically.

Does payment history stay with the client?

Yes. Full payment history is tied to the client record, alongside their calls, proposals, and project activity.
