Build a Travel Agency Invoicing App with AI

Travel agency invoicing is two invoices per trip at least, a deposit and a balance, timed against what you owe suppliers. Describe your payment terms and Mythex builds an app that raises both, splits group trips per payer, records cancellations and shows what is outstanding, with PDFs you can send.

Who it's for

Agencies issuing invoices from a word processor template, tracking balances in a spreadsheet, and chasing a late payer days before a supplier deadline.

What you can build

A deposit invoice on booking and a balance invoice dated before supplier deadlines
One invoice per paying party on a group trip, with a group total
Service fees shown separately from supplier costs where you need that
Cancellation charge invoices linked to the original booking
A list of balances due this week and overdue
Printable PDF invoices with your branding

Time balances against supplier deadlines

If the hotel needs full payment eight weeks before arrival and your client pays on the last day you allowed, you have no room to chase. Store each supplier deadline on the trip and set the client balance date a week or two earlier automatically. The app then shows which balances are due soon, which are late, and which supplier payment depends on each one.

Balance date = earliest supplier deadline minus a buffer
Overdue list sorted by the supplier deadline at risk
Reminder emails through a service you connect

Group trips with several payers

A school group, a hen party or three families sharing a villa rarely pay as one. Create an invoice per paying traveller or household, all linked to the same trip, and show the group's total paid and outstanding on one screen. The group organiser sees who has paid without you forwarding emails.

Cancellations and amendments

When a client cancels or changes dates, raise the charge as its own invoice or credit note linked to the original booking, with the reason. Keeping the link means your records show the full history of a trip, which matters when an insurer or a client asks later what was charged and why.

Tax and payments

Tax on travel services varies by country and by how you sell, so tell Mythex which rates and lines apply and check the treatment with your accountant. For online payment, connect a payment provider on your own business account and ask for a pay-now link on each invoice.

A prompt to start from

Build an invoicing app for my travel agency. Each trip gets a deposit invoice when booked and a balance invoice due 14 days before the earliest supplier deadline on that trip. Group trips get one invoice per paying traveller linked to the trip, with a group paid and outstanding total. Add cancellation charge invoices linked to the original booking, PDF invoices with our logo, and a list of balances due this week and overdue.

Questions

Can each traveller in a group pay separately?

Yes. Ask for an invoice per paying traveller linked to the same trip, and the app shows the total paid and outstanding for the whole group.

Can it produce PDF invoices?

Yes. Mythex builds a printable invoice layout with your details, logo and numbering that you can download or attach to an email.

Can clients pay the deposit online?

Yes, by connecting a payment provider on your own business account. Mythex adds a pay-now link to each invoice that uses it.

Do I need to code?

No. You describe your terms and the app in plain language and change it by chatting.

Is there a free plan?

Yes. The Free plan needs no credit card and gives daily credits, enough to build and publish a first version. Pro is $25/month.
