Invoice app builder

An invoice app that gets you paid.

Send the invoice, take the card, and see who has paid and who still owes in one list. The money lands in your own Stripe, never with us.

What does an invoice app need?

Everything it needs, already working.

The invoice goes out, the card goes through and you hear about it the moment it does. All of it works from the first version, built from parts every app shares.

Questions

Invoice apps,
answered.

01Can I make my own invoice app without code?Yes
Yes. Describe how you bill in one sentence and plan it free. The first version is usually ready in under half an hour, and you never touch code.
02How do clients pay an invoice?By card
By card, on a Stripe checkout page, for the fee you set in the app. The money goes straight into your own Stripe account, and Lynqly never holds it.
03Will it chase unpaid invoices for me?Not on its own
Not on its own. Each client gets an email when a new invoice is ready, you get one when a card goes through, and you mark each invoice paid in your Admin, so you always see who still owes.
04Is there a fee per client or per invoice?No
No. There’s no seat fee and no per-invoice fee. Our fee is 1% or less of each payment, and nothing when nothing gets paid.
05Who can see my clients’ invoices?Only who you choose
Every collection is private until you say otherwise. Set it so each client sees only their own invoices, and you see all of them.
06Can I export my invoices and client list?Yes
Yes, on every plan. Export your pages, your data and your members’ logins as a project that runs on any server with Node and Postgres. The engine is Fair Source, and every release becomes MIT two years after it ships.

Send the invoice. Get paid by card.
