Plumber booking system that turns callouts into repeat customers
Plumbing is full of one-off jobs that should have been the start of a relationship. Bookso is the booking system that helps you turn each callout into a customer who books you again next year.
Free for your first 5 customers. No card required.
Your customer list
Every customer in one place.
Auto-scheduled reminders
Service due? We send the nudge.
They tap, you book
Customers book themselves in 30 seconds.
Every time you finish a job, you add the customer to Bookso and pick when you would like to see them again. That might be a 12-month annual check on a hot water cylinder, a 6-monthly tap and seal inspection, or a yearly outside tap and stopcock check before winter. Bookso schedules the next reminder automatically and sends a booking link from your business name on the due date.
Because reminders go out by email with a one-tap booking link, customers do not need to ring up to rebook. They pick a slot from the times you have set as available and the job lands in your pipeline. You can pre-fill the job type, address and price so there are no surprises on the day.
Bookso also helps you offer a simple annual plumbing check-up service. Add it as a job type, set the interval to 12 months, and every customer you add becomes a candidate for a yearly visit. You decide who to invite. It is a low-pressure way to fill quieter weeks without door-knocking or paid ads.
There is no contract and no setup fee. Your first 5 customers are free so you can try it on a handful of regulars before moving everyone across. Paid plans start at £14.99/month with unlimited customers and branded reminders.
The problem
You finish the job, take payment, and drive off. That's usually the last time that customer ever hears from you. Twelve months later their kitchen tap starts dripping or their cylinder makes an odd noise, and they don't ring you - they Google 'plumber near me' and hand the job to a total stranger who happens to be top of the list that morning.
It's not that the customer didn't like you. It's that you never gave them a reason to remember your name at the exact moment they needed a plumber again. Repeat work is where the money is in plumbing - annual cylinder services, landlord maintenance visits, powerflush follow-ups, seasonal outside-tap checks - and most self-employed plumbers are quietly losing all of it to whoever's got a better Google ranking in 2026.
The fix isn't more marketing. It's remembering to speak to the customers you've already got, at the right moment, without spending your Sunday evening scrolling through invoices and typing texts.
How Bookso works for plumbers
When you finish a job, you log the customer in Bookso and pick when you'd like to see them again. Annual plumbing check-up? Set it to 12 months. Unvented hot water cylinder service? 12 months by G3 recommendation. Powerflush follow-up to check the system's still running clean? 6 or 12 months, your call. Landlord maintenance visit on a rental? Whatever cycle the landlord's agreed. That's the whole setup - a customer and an interval.
About a month before the job's due, Bookso emails the customer from your business name with a one-tap booking link. They pick a slot from your availability, the job lands in your diary as a confirmed booking, and you get a notification. No back-and-forth about dates, no voicemails, no 'I'll get back to you.'
If they don't tap the link within a few days, Bookso sends an automatic chaser. If they still don't book, one SMS follow-up goes out on the paid plans. After that Bookso stops - the customer stays visible in your pipeline so you can phone them yourself or leave them for now. You're in charge, but the nagging isn't your job any more.
The important bit: Bookso is a booking system, not just a reminder tool. Most reminder software fires an email and calls it done. The customer still has to ring you, which most won't. Bookso closes the loop so a reminder actually becomes a confirmed booking in your diary.
The unvented cylinder opportunity
Most homeowners with an unvented hot water cylinder have no idea it's supposed to be serviced every 12 months. They were told at installation, forgot within a week, and haven't thought about it since. Meanwhile the manufacturer's warranty quietly requires annual servicing to stay valid - and the expansion vessel, T&P valve and tundish absolutely do need eyes on them once a year, G3 or not.
This is one of the biggest under-worked repeat jobs in domestic plumbing. The plumber who installed the cylinder is normally the one who should service it, but almost nobody rings back for it because nobody reminds them. If you're the plumber who does remind them - politely, with a booking link, from an email that says your name - you own that job for the life of the cylinder. That's 10 to 15 years of annual work per customer, on a job that takes an hour or so and pays well.
Bookso lets you set unvented cylinder service as its own job type with a 12-month interval and its own price. Every customer you've fitted a cylinder for goes on the list automatically. You don't have to remember any of them - the software does.
Why plumbers switch from bigger job-management apps
Full job-management suites like Commusoft, Powered Now, Fergus and Tradify do a lot: quoting, invoicing, timesheets, parts, engineer scheduling. They're capable pieces of kit, and they cost roughly £30 to £70 per user per month once you're on a real tier. They also take a weekend to set up properly.
Bookso doesn't try to run your whole business. It does one thing: get the customers you've already got to book you again, automatically. Setup is about 5 minutes - add a customer, pick an interval, done. Pro is £14.99/month for unlimited customers, Business is £44.99/month if you take on a mate or an apprentice.
Plenty of plumbers keep their existing invoicing tool or their spreadsheet and just add Bookso alongside it for the rebooking loop, which the bigger suites don't do well. You don't have to move anything.
Works alongside your existing tools. Already using Powered Now, Commusoft, Fergus, Tradify, QuickBooks or a spreadsheet for your invoicing? Keep them. Bookso is designed to sit alongside your existing tools rather than replace them - it handles the customer-side rebooking loop so your invoicing setup can stay exactly as it is.
Frequently asked questions
What plumbing jobs repeat every year?
More than most plumbers realise. Unvented hot water cylinder services (12 months, needed to keep manufacturer warranties valid), annual plumbing check-ups, landlord maintenance visits, powerflush follow-ups, water softener servicing, outside tap and stopcock checks before winter, and seasonal boiler-adjacent plumbing work. Bookso lets you set each job type to its own interval and reminds the customer automatically when it's due.
Can it remind landlords about annual maintenance?
Yes. Each rental property is tracked as its own customer record with its own maintenance schedule. Bookso sends the landlord a reminder from your business name before each visit is due, with a one-tap booking link showing your availability. Portfolio landlords with several rentals get one reminder per property, staggered through the year, so renewals don't all pile up in the same week.
How do reminder texts and emails work?
When the job is due, Bookso emails the customer from your business name with a one-tap booking link. They pick a slot from your availability and the job lands in your diary as a confirmed booking. If they don't respond after a few days, an automatic email chaser goes out, and on the paid plans one SMS follow-up. There's no app for the customer to install - it all works from any phone or laptop.
What if the customer ignores the reminder?
Bookso sends one automatic email chaser after a few days, and on the Pro or Business plan one SMS follow-up if they still haven't booked. After that Bookso stops - the customer stays visible in your pipeline so you can phone them yourself or leave them. Bookso will never keep spamming a customer who's clearly not interested.
How much does it cost for a plumber?
Your first 5 customers are free forever, no card required. Pro is £14.99/month (or £149/year, which is 2 months free) for unlimited customers, email and SMS reminders, chasers and CSV import. Business is £44.99/month (£449/year) and adds team members plus more SMS credits. No setup fee, no contract, cancel from settings whenever you like.
Do I have to move my invoicing over to Bookso?
No. Bookso doesn't do invoicing and doesn't try to. Keep whatever you already use - Powered Now, Fergus, Commusoft, QuickBooks, a spreadsheet, a paper invoice book - and use Bookso only for the customer-side rebooking loop. Most plumbers on Bookso keep their existing invoicing tool exactly as it was.
