On the Go Quoting and Invoicing in 2026: 6 Software Picks for Small UK Trades Businesses
Earning money in the trades happens on site rather than at a desk. Throughout the day, joiners, plumbers, decorators and electricians travel from one job to the next, and the evening is then spent writing quotes, sending invoices and finding receipts collected in the van door. Hours lost to paperwork are hours not spent working or resting. Invoices sent out late also tend to get paid late.
The good news is that most of that admin can now be done from a phone, whether you are between jobs or still on the customer's driveway. The six software picks covered here help small UK trades businesses quote, invoice and get paid on the go.
1. Sage Accounting: Phone-Friendly Quotes, Invoices and Payments
Sage Accounting gives you the ability to create professional quotes and invoices that include your logo and details, and to send them by email from your computer or phone. A few clicks turn an accepted quote into an invoice once the job is done, avoiding retyping so nothing gets missed.
Automated reminders take care of chasing slow payers, and you can see what you are owed at a glance. Through GoCardless and Stripe, customers can pay online, and with automatic bank reconciliation, payments are matched to invoices without you ticking off statements for an evening. For VAT registered users, Sage Accounting calculates and submits VAT returns and keeps you Making Tax Digital ready, so the quarterly return is a quick check, no longer a weekend job.
2. WhatsApp Business: Tidy Customer Messages
A phone call is less appealing to most customers than a quick message, and plenty of them already message tradespeople on WhatsApp. WhatsApp Business divides work chats from personal ones and adds tools such as a business profile, quick replies for common questions and automatic away messages while you are working on a job.
Nothing gets forgotten when labels tag each chat by stage, for example new enquiry, quote sent or awaiting payment. You get a simple way to appear more professional, and there is no new system to learn.
3. Quartix: Vehicle Tracking and Mileage Reports
Vans are a significant cost to trades businesses, as well as serving as their office. Quartix is a UK vehicle tracking system. It records where each van travelled, and when, and produces journey histories and mileage reports so no one has to fill in a logbook.
Separating private use from business use is made easier by accurate mileage records, and journey histories can settle questions about when you arrived at or left a job. If you run more than one van, live tracking also helps you send the nearest person to an urgent call out.
4. PayPal Point of Sale (Formerly Zettle): Card and Contactless at the Door
A wait of days for a bank transfer slows your cash flow, and plenty of customers have stopped keeping cash in the house. A compact card reader from PayPal Point of Sale pairs with your phone, allowing customers to pay by card or contactless the moment a job is finished.
When a job is larger or a deposit is needed, payment links let you take a card payment remotely, by email or by text. Payment on the spot cuts the number of invoices you need to chase and gives you a clearer picture of what has actually come in.
5. MyBuilder: A Source of New Local Work
Relying only on word of mouth can leave gaps in the diary, and for many trades businesses quiet weeks are a fact of life. MyBuilder is a UK platform where homeowners post jobs and local tradespeople can express interest, and feedback from previous customers appears on your profile.
Over time, a growing body of positive feedback helps you win work from people who have never met you. Deciding which jobs to respond to also lets you fill quieter weeks with work that fits your skills and location.
6. CompanyCam: Job Photos With Notes Attached
Before and after photos make great material for your website and social media. They also protect you should a customer dispute the work later. CompanyCam is a photo documentation app that automatically organises photos by job and location, complete with notes and time stamps.
You get a dedicated record for every job rather than hundreds of unlabelled pictures in a camera roll, and it can be shared with suppliers, customers or a colleague in a couple of taps. The quotes and invoices you send are backed by clear evidence of what was done, and when.
What a Connected Setup Means for Your Working Day
Consider how a connected setup changes an ordinary working day.
8am: WhatsApp Business receives a new enquiry while you are loading the van, and you tell the customer when you can visit with a quick reply.
11am: You price a job on site, and the quote leaves your phone before you leave the driveway.
2pm: When the repair is done, you take before and after photos, turn the accepted quote into an invoice and collect a card payment on the doorstep.
5pm: The day's mileage is logged by your van tracker already, while your integrated online payments have flowed into your accounts.
7pm: Paperwork no longer fills the evening. It is yours.
FAQs
Is it possible to turn a quote into an invoice after finishing the job?
Yes. An accepted quote can be converted into an invoice in a click in Sage Accounting. The details agreed with the customer then carry straight through, with nothing to retype.
How can I let customers pay immediately?
On the spot, customers can pay by card or contactless using a portable card reader, while payment links suit deposits or remote payments. Sage Accounting also supports online payments for invoices through GoCardless and Stripe, so payment can be made as soon as the invoice arrives.
What is a good system for organising photos from each job?
Pick an app that files photos by job automatically instead of keeping them in your camera roll. With a short note added to each photo, the right picture is far easier to find when a customer has a question months later.
Is it a good idea to keep customer messages on a separate number?
It helps. With WhatsApp Business on a separate number from your personal account, work chats are kept in one place, and switching off at the end of the day is easier.
