Paint it black.

Modules

One system. Every part of the floor.

Blackdoor isn't just a register — it's the modules a full-service restaurant or hotel actually runs on, all synced through the same offline-first core. See every module in depth →

Tables & Floor Plan

Visual floor layout, table status, and split or merged checks in one view.

Reservations

Bookings, waitlists and table holds that stay in sync with the floor.

Kitchen Display

Tickets route straight to the kitchen screen the moment an order fires.

Payments & Split Checks

Card, cash and split-tender checkout, with fast void and refund flows.

Catalog, Pricing & Promotions

Menus, price lists and time-based promotions, managed per branch.

Customers & Loyalty

Guest profiles, visit history and points that follow the customer anywhere.

Gift Cards

Issue, reload and redeem gift cards across every device on the floor.

Staff, Roles & Shifts

Clock-in, shift schedules and role-based permissions, down to the action.

Hotel Room Charges

Post a check straight to a guest's room folio at checkout.

Multi-Branch & Franchise

Franchisee data stays isolated; franchisors see roll-up reporting across branches.

Inventory & Procurement

Stock counts and purchase orders tied to what's actually selling.

Fiscal Invoicing & Tax

Compliant invoices and tax rules that adapt to where you operate.

Why teams switch to Blackdoor

Never lose a sale

Internet outage, router reboot, dead wifi — orders keep flowing. Every device persists locally and syncs the moment a connection appears.

Every device, one truth

Waiters, the bar, the kitchen display, the front desk — every screen sees the same table and the same order in real time, no cloud round-trip.

Built for real service

Tables, tabs, room charges, split checks — the workflows your floor actually runs, not a generic checkout bolted onto a tablet.

How the sync works

01 — One device leads

Any tablet or terminal on-site can become the master — no special hardware required.

02 — Every device joins

Waiter tablets, the kitchen display, the front desk — all connect over your own local network.

03 — Everything syncs instantly

Orders, tables and payments update everywhere in real time — network or no network.
