Integrations
I plug into the 9,000+ tools you already use.
Your accounts, your card payments, your calendar, your WhatsApp and your reviews, all connected. I keep them in sync in the background, so nothing gets typed twice and nothing drifts apart.
No card needed. Unlimited for 14 days. Cancel any time.
Your books keep themselves
Raise an invoice in Mucka and it lands in your accounts on its own. Payments and contacts sync the same way, and I pull your existing clients across in one tap when you join.
Xero Two-way sync for invoices, payments and contacts, plus one-tap import of your existing clients. 
QuickBooks Invoices, payments and contacts flow straight into QuickBooks. Bring your client list across in a tap. 
FreeAgent Full sales sync with FreeAgent, live for everyone. Import your existing book in one tap. 
Sage Two-way sync for invoices, payments and customers, with your existing Sage book imported in one tap. Getting paid stops being a chase
Card or bank transfer on the invoice, a QR code at the door, and Direct Debit for the customers on a service plan. Take cards through Stripe or the SumUp account you already have, and bank payments through GoCardless. The money settles into your own account rather than passing through me, and every payment records itself against the invoice and goes out to your accounts.
Stripe A Pay button on every invoice, and a QR code at the door. Card, Apple Pay and Google Pay. 
SumUp Already take cards with SumUp? The Pay button on your invoices sends the money into your SumUp account. 
GoCardless A Pay by bank transfer button on every invoice, capped at £4, and Direct Debit for your service plans. 
Coming soon Apple Tap to Pay Hold the customer’s card or phone against your iPhone and take the payment. No reader to buy. Already running on something else?
You do not always have to rip it out. I plug into JobLogic and sit on top of it. If you are on Commusoft, Gas Engineer Software, Tradify, Payaca, Gas App or Powered Now there is a purpose-built importer waiting, and if you are on anything else, ask your old provider for your data and I will get it in here tidy. What comes across depends on what your old system will export, so talk to me before you cancel.
JobLogic Keep JobLogic as your system of record and let me sit on top of it. 
Moving from Commusoft A purpose-built importer, not a spreadsheet of contacts. Moving from Gas Engineer Software Your certificates come across with their signed PDFs. Moving from Payaca Every customer, and what each job was quoted, invoiced and paid. Moving from Tradify Every customer and every site they own, tidied on the way in. Moving from Gas App I read your invoices and quotes and build your customer book from them. Moving from Powered Now Every customer, everyone on their record, and every address as its own property. Moving from anything else Request your data from your old provider and I will get it in here tidy. In step with the rest of your day
The diary, the chat and the reviews you already live in. I connect to them so the schedule stays true and nothing needs chasing by hand.
Google Calendar Two-way sync. Your events block out the Schedule, your Mucka jobs appear in Google Calendar. 
Outlook Calendar The same two-way sync for Outlook and Microsoft 365, with clash detection built in. 
Apple Calendar Your Mucka jobs in the Calendar app on your iPhone, iPad or Mac, kept up to date. 
WhatsApp Two-way messaging with your engineers, and confirmations, quotes and invoices to your customers from your own number. 
Google Reviews I watch your Google Business Profile, pull in new reviews and post your replies back to Google. Your marketing finds out when the job is done
If your leads and follow-ups run in Go High Level, or an agency runs it for you, connect it to me. New leads and bookings come into Mucka without anyone retyping them, and I tell Go High Level when a job is done or an invoice is paid, so your review requests start on their own.
9,000+ more apps, through Zapier
Your website form, your Facebook leads, your Google Sheet, your Gmail. Through Zapier, work comes into me from the apps you already use, and I can use those apps for you, asking first whenever you want me to. And if you already use ChatGPT or Claude, you can add me there and ask about your work.
