Phone (display)iHuman-readable version of the phone number shown in the booking form and emails. E.g. 01934 644 427.

Email displayiContact email shown to customers in the booking form and emails. Also used as the Reply-To address on all outbound customer emails — so customer replies go to your business address rather than the sending Gmail. If left blank, replies default to the sending address.

Notification emailsiBCC recipients for every confirmation email. Enter one or more comma-separated email addresses — e.g. your workshop inbox and a manager. They receive a copy of each booking confirmation without the customer seeing them in the To field.

Branding

Brand colouriPrimary brand colour — used for buttons, selected states, highlights, and key UI elements throughout the booking form. Choose a colour that matches your brand.

Background colouriPage background colour for the booking form. Dark themes use near-black (e.g. #111111); light themes use near-white.

Surface colouriColour for cards, modals, and elevated surfaces. Should be slightly lighter than the background to create visual depth.

Muted text colouriSecondary / hint text colour — used for labels, placeholders, and supporting information. Should be a softer version of the text colour (e.g. #888888 on dark, #555555 on light).

Theme presetiQuickly apply a pre-built colour scheme. Selecting a preset overwrites the colour fields above — you can then adjust individual colours after applying.

Schedule

Opening hour (24h)iFirst available booking slot of the day. E.g. 9 = slots start at 09:00.

Closing hour (24h)iNo booking slot can end after this hour. E.g. 17 = last slot must finish by 17:00.

Allow same-day bookingiWhen off, today's date is never available — the earliest selectable date is tomorrow. Use with "Min hours ahead" for finer control.

Min hours aheadiMinimum lead time before a slot can be booked. E.g. 4 = slots within the next 4 hours are hidden. 0 = no minimum. Works in combination with same-day booking.

Slot intervaliHow frequently booking slots appear. Hourly = 09:00, 10:00, 11:00. Half-hourly = 09:00, 09:30, 10:00, 10:30. Choose based on your typical service duration.

Pricing

Deposit amountiGlobal holding deposit charged at checkout. Deducted from the final invoice on the day. Individual services can override this in the Services tab.

Invoice prefixiThe prefix before the invoice number — e.g. INV, MET, your business initials. Combined with the number to produce e.g. INV-00001.

Next invoice numberiThe next auto-generated invoice number. Change this to align with your existing numbering — e.g. set to 501 if your last manual invoice was 500. Numbers increment automatically after each invoice.

Zero paddingiHow many digits the number portion should be padded to. 5 = INV-00001, 4 = INV-0001, 3 = INV-001.

Payment termsiShown on the invoice under the totals — e.g. "Balance due on completion of work" or "Payment due within 14 days".

Invoice footer noteiOptional text at the bottom of every invoice — e.g. bank details for BACS payment, thank you message, or legal disclaimer.

Booking messages

Expired MOT/Tax acknowledgementiWhen enabled, customers booking via DVLA VRN lookup are shown a mandatory acknowledgement checkbox if their MOT or Vehicle Tax is expired or not valid. They must confirm they will arrange legal transportation and acknowledge the vehicle may not be test-driven on public highway.

Business policyiYour combined business policy shown as a collapsible "[Business Name] Policy Agreement" checkbox on the payment step. Can include cancellation terms, T&Cs, and any emissions disclaimer. Customer must expand and agree before paying. Leave blank to hide.

Arrival noteiShort instruction shown at the bottom of confirmation emails and the booking summary. E.g. "Please arrive 5 minutes early. Call us if you are running late."

Confirmation email introiOpening paragraph in the confirmation email sent to the customer after payment. E.g. "Your booking has been confirmed. We look forward to seeing you."

Show invoice address fieldiWhen enabled, the booking form shows an Invoice Address field where customers can enter a billing or correspondence address. This address appears on invoices and confirmation emails. Disable if you do not need to collect an address from customers.

Require invoice addressiWhen on, the invoice address field is mandatory — the customer cannot proceed without entering it. When off, the field is shown but optional. Only relevant when "Show invoice address field" is enabled.

Collect business details on booking formiWhen enabled, the booking form shows an optional "Business Details" section where customers can enter their Business Name, VAT Number and PO Number. All fields are optional — customers can leave them blank. Useful for B2B customers who need these details on invoices.

Mobile service mode

Mobile modeiEnable for mobile/van-based services where you travel to the customer. The booking form will collect the customer's address, and the system uses the Google Routes API to check travel feasibility between jobs and create travel-block calendar events.

Show travel estimateiWhen on, shows the estimated drive time and distance from your base to the customer on the booking confirmation.

Work start timeiThe time you leave your base at the start of the day. Used to check whether you can feasibly travel to the first customer in time. E.g. if set to 08:00 and the drive takes 45 min, the earliest slot offered will be 08:45.

Max coverage (miles)iMaximum driving distance you'll travel from your base to a customer. Bookings outside this radius are blocked. 0 = no limit.

Blocked dates

Specific dates that are completely unavailable — e.g. bank holidays, shutdowns.

No dates blocked

Calendar block keyword

If any Google Calendar event title contains this keyword, all booking slots for that entire day are hidden from customers. Leave blank to disable.

Block keywordiCase-insensitive. If a calendar event title contains this text, all slots for that day are removed from the booking form. Useful for holidays, training days, or custom closures — just add the keyword to a Google Calendar event.

Example keyword: [BLOCK]
Example event title: "Staff Training [BLOCK]"

Google Calendar (fallback / single-staff)

Used when no calendars or staff are assigned to a service. If you use the Calendars & Staff tab to assign them to services, each one's own calendar ID is used instead.

Calendar IDiFound in Google Calendar → Settings → your calendar → "Integrate calendar" section. Looks like abc123@group.calendar.google.com or your Gmail address for the primary calendar.

Share this calendar with the Cloud Functions service account email (shown in Firebase Console → Project Settings → Service accounts) and grant it "Make changes to events" permission.

Custom email sender (optional — most tenants leave this blank)

You do not need to fill this in. METBooker sends all customer emails automatically using the shared bookings@metbooker.com address. Customer replies are routed to your Email display address set in Contact.
Only fill in these fields if you want emails to come from your own Gmail address — this requires your own Gmail account with 2-Step Verification and an App Password.

Gmail address (sender)iThe Gmail address confirmation emails are sent from. Must be a Gmail or Google Workspace address with 2-Step Verification enabled so you can create an App Password.

Gmail app passwordiNot your Google account password — this is a 16-character app-specific password.

How to create one:
1. Go to your Google Account → Security
2. Enable 2-Step Verification (required)
3. Search for "App passwords"
4. Create a new app password for "Mail"

Leave blank to keep the existing password.

Loading…

In Stripe Dashboard → Developers → Webhooks, click Add endpoint, paste the URL above, and subscribe to: checkout.session.completed. Copy the Signing secret (starts with whsec_) into the field below.

Stripe webhook secretiGenerated by Stripe when you create a webhook endpoint. Starts with whsec_.

Stripe deposit price ID (Stripe only — optional)iOptional Stripe Price ID (starts with price_) for the deposit product. If set, Stripe uses this fixed price instead of creating an ad-hoc price. Global default — individual services can override it in the Services tab.

Allow customers to pay in full at checkoutiWhen enabled, the booking form shows two options on the payment step: "Pay deposit" (the usual amount) and "Pay in full" (the total invoice amount). If the customer pays in full, no balance is due on the day. Works with all payment providers.

Accepted payment methodsiTick every payment method you accept. These are shown on the checkout page and booking confirmation so customers know what to bring / how to pay the balance on the day.

Visa Mastercard Amex Maestro Apple Pay Google Pay Cash Bank Transfer

Google Tag Manager / Analytics

Track your booking funnel in Google Analytics 4. METBooker fires a booking_completed event when a customer pays — use it for conversion tracking, remarketing audiences, and GA4 funnel reports.

GTM Container: not set GA4 ID: not set Server-side GA4: not set

Booking form GTM IDiGTM container for the booking form. Format: GTM-XXXXXXX. This is the container you download and import using the button below. The booking form and confirmation page both load this container.

Website GTM ID (reference)iYour main website's GTM container ID — stored here for reference only. METBooker does not load this container directly. Format: GTM-YYYYYYY.

GA4 Measurement IDiYour GA4 property Measurement ID. Format: G-XXXXXXXXXX. Found in GA4 → Admin → Data streams → select stream → Measurement ID. Used by the GTM container to send events to your GA4 property.

GA4 API SecretiEnables a second, server-side booking_completed event sent directly from METBooker's Cloud Function after payment is confirmed — more reliable than client-side GTM because it fires even if the customer closes their browser early.

Create one in GA4 → Admin → Data streams → select stream → Measurement Protocol → Create API secret. Leave blank to disable.

How to connect GA4 — 5 steps

1

Create a GTM container for the booking form
Go to tagmanager.google.com and create a new Web container (or use an existing one). Copy the Container ID (format: GTM-XXXXXXX) and paste it into Booking form GTM ID above.

2

Enter your GA4 Measurement ID
In GA4 go to Admin → Data streams → your stream → Measurement ID. It starts with G-. Paste it into the GA4 Measurement ID field above.

3

Save settings, then download the pre-built GTM setup
Click Save settings first so your GA4 Measurement ID is stored. Then click Download Booking Form GTM Container below — this generates a ready-to-import JSON file with all tags pre-configured.

4

Import the JSON into your GTM container
In GTM go to Admin → Import Container → select file → choose the downloaded JSON → select Existing workspace → Merge → Rename conflicting tags → click Confirm. Then click Submit to publish.

5

(Strongly recommended) Add server-side tracking
In GA4 go to Admin → Data streams → your stream → Measurement Protocol → Create API secret. Copy the secret and paste it into GA4 API Secret above. This fires a backup booking_completed event from the server — it works even if the customer closes their browser before the confirmation page loads.

What gets tracked The booking_completed event fires on the confirmation page after payment succeeds. It includes:
service_name · booking_value (deposit paid) · currency · payment_type (deposit / full)

Two methods run in parallel:
Client-side (GTM): fires from the confirmation page via the booking form GTM container. Relies on the customer's browser loading the confirmation page.
Server-side (GA4 API Secret): fires from METBooker's Cloud Function immediately after payment is confirmed. More reliable — works even if the browser closes early. Requires the GA4 API Secret field to be set.

Advanced

Priority booking codeiSecret code that unlocks a hidden fast-track booking mode for priority customers (e.g. fleet clients). Share the code privately — customers enter it on the booking form to access priority slots.
