Most lash tech software gets judged in its first month, usually the first time a full set does not show. A booking app for lash techs should make your policy easy to agree to before the client lies down: a deposit, a signed form and, if you use one, a card on file. KadePay keeps those steps together, and payment never happens inside the booking request itself.
A lash extension deposit works best when it is the same every time. Send a fixed link when you confirm the request, and on Team or Pro use a vanishing bill so an unpaid hold expires. Put the eyelash extension consent form and your lash patch test questions in one short form, so returning clients are not signing the same page at every visit.
Fills keep a lash business steady. A written lash fill policy, with two or three weeks between visits and a foreign fill price for clients coming from another artist, sets expectations early. Fill packs or a lash membership reward the clients who stay on schedule, and your lash aftercare can sit in the receipt text of your payment links so every client leaves with the same instructions.
