Hotel Invoicing App: Folios, Split Billing, Events and City Tax

Hotel billing goes wrong at the split: the company agreed to pay the room and breakfast, not the bar. Tell Mythex how your hotel charges and it builds an invoicing app with folios, charges assigned to the right payer, event deposits and a paid and overdue list.

Who it's for

Hotels that rebuild company invoices in a document after checkout, chase event balances by email and argue with accounts departments over extras that were never agreed.

What you can build

Folios listing room nights, restaurant, bar and extras by date
Charges assigned to the company or the guest at booking
Two invoices from one stay when payers differ
Event invoices with deposit, final numbers and balance date
City or tourist tax on its own line
Paid, unpaid and overdue lists for accounts

Decide who pays at booking, not at checkout

Record the billing arrangement when the room is booked: company pays room and breakfast, guest pays everything else. Put it on the confirmation. When charges land on the folio they go to the right payer automatically, and the guest is not surprised at the desk.

Event invoices in stages

Weddings and conferences bill in steps: a deposit to confirm, an interim payment, and a final invoice once head counts are fixed. Give each event a schedule of payments with due dates, and the final invoice uses the confirmed numbers, not the original estimate.

Deposit on contract
Interim payment date
Final invoice from confirmed numbers

Taxes and accounts

City or tourist tax goes on its own line per guest per night where it applies. Rates and rules differ by location, so confirm them locally. Corporate accounts on credit get monthly statements and overdue reminders.

Mistakes to avoid

Do not edit an issued invoice; issue a credit note. Do not mix event deposits with room revenue in reports. And keep card details with your payment provider, never in the invoicing app.

A prompt to start from

Build an invoicing app for my hotel. Each stay has a folio with room nights, restaurant, bar and extras by date. Each charge is assigned to the company or the guest, producing separate invoices. Add city tax per guest per night, event invoices with deposit, interim and final payments, monthly statements for corporate accounts and an overdue list.

Questions

Can one stay be billed to two different payers?

Yes. Charges can be assigned to the company or the guest, producing two invoices from one stay.

Can invoices be sent as PDFs?

Yes. Ask for a PDF download. Emailing invoices automatically needs an email service you connect with your own account.

Can guests pay an invoice online?

Yes, with a pay link from a payment provider such as Stripe that you connect yourself.

Do I need to code?

No. You describe how you charge and adjust it by chatting.

Is it free to try?

Yes, the Free plan needs no card. Pro is $25 a month for a custom domain, code editing, export and more credits.
