Best All-in-One App for Electricians: Certificates and Invoices in One (UK 2026)
A 2026 comparison of all-in-one apps that do electrical certificates and invoicing together for UK electricians, so EICRs sit in the same tool as your quotes, invoices and payments.
Best All-in-One App for Electricians: Certificates and Invoices in One (UK 2026)
Plenty of apps do electrical certificates. Plenty do invoicing. Fewer do both well in one place, so an EICR you issue on site turns into an invoice without re-keying a thing. This guide compares the tools that put certificates and getting paid in the same app.
By Daniel Sedgwick, Founder of Checker and a former gas engineer
Ask most electricians where their admin time goes and the answer is rarely the testing. It is the shuffle around it: certificate in one app, quote in another, invoice in a third, and the customer’s details typed into all of them. A certificate only tool leaves that shuffle in place.
An all-in-one app is worth it when the certificate and the money live together. You complete an EICR on site, and the same tool raises the invoice against the same customer, chases it if it goes unpaid, and keeps the certificate on file for when the landlord or letting agent asks. The re-keying disappears, and so does the risk of a certificate that never gets billed.
The tools below all touch electrical certificates, but they differ on whether invoicing and payment are genuinely part of the same app or a separate concern. They are listed in display order, not ranked. For the certificate side in isolation, our guide to the best EICR and electrician software goes deeper.
Key takeaways
- The value of all-in-one for an electrician is that the certificate and the invoice share a customer and a job, so an EICR issued on site becomes an invoice with no re-keying.
- iCertifi is a strong certificate tool but has no native invoicing beyond a beta add on, so most users still run a separate billing tool alongside it.
- Checker puts native electrical certificates, invoicing, automated chasing and on site card payment in one app, works offline, and syncs to Xero, QuickBooks and Sage, from £10.99 per month plus VAT with no lock-in.
- Tradify offers certificates and strong invoicing together but has no offline mode, so it suits electricians whose sites reliably have a connection.

iCertifi
iCertifi is a certification first platform with purpose built templates, and certificates are its core strength. It works offline natively, which suits electricians whose main need is producing EICRs, EICs and Minor Works quickly on site.
Where it stops is the money side: there is no native invoicing beyond a beta add on, and accounting is limited to a beta of its own Mint Books tool. Pricing is per app rather than a single figure: the entry level Fire Safe app starts around £14.99 a month, while individual trade apps such as the GasCert gas app are around £25.99 a month. For sole traders focused mainly on certification it is capable; for running the whole business it usually needs a second tool alongside.
Checker
Checker is a compliance certificate platform that also runs the rest of the job, which is the point of an all-in-one. Electrical certificates sit alongside a job list, scheduling and a customer record, native invoicing, automated chasers and on site card payment, so an EICR you issue becomes an invoice against the same customer without re-keying, and gets chased automatically if it is not paid.
It is mobile first and works offline, syncing on reconnect, and it syncs two way with Xero, QuickBooks and Sage. Pricing starts from £10.99 a month plus VAT with no lock-in. For electricians who want certification, job management and getting paid in one app rather than three, it is built for exactly that. Our guide to job management software for UK electricians covers the wider workflow.
Tradify
Tradify pairs strong job and quote management with native electrical certificates, though certificates are gated to the Pro tier. Invoicing is strong, so certificates and billing do sit in one tool.
The catch for on site work is that Tradify has no offline mode, so it needs a connection to do its job. Pricing runs £34 to £44 per user per month in the UK. Best suited to firms with reliable site signal wanting job, quote and certificate management together.
Powered Now
Powered Now offers electrical templates covering EICR, EIC, MEIC and PAT on its Pro plan and above, with a strong quote to invoice focus and confirmed native offline working.
Accounting sync covers the common UK packages. Pricing sits at £28 to £40 per user per month, excluding VAT. A solid fit for sole traders who want reliable offline paperwork and fast document production.
Commusoft
Commusoft is a compliance trade platform built for scale, with certificates and invoicing both present and a dispatch focused workflow.
Commusoft documents a native true offline mode, giving field engineers access to job details, forms and asset histories with no connectivity, then syncing on reconnect. Plans are quote or demo only, designed for teams of six or more. A strong all-in-one for established multi engineer firms with contract work, heavier than a sole trader usually needs.
Joblogic
Joblogic brings certification modules and invoicing together within a platform built for multi engineer dispatch and larger commercial operations.
Joblogic states that its mobile app works both on and offline, with work automatically sent to the back office when signal returns. The headline price is £45 per user per month billed annually, with Premium and Enterprise tiers quote only. Best suited to larger, multi engineer commercial operations.
What to look for in an all-in-one
All-in-one is only worth it if the pieces genuinely join up. When you are shortlisting, the questions that separate a real all-in-one from a certificate app with billing bolted on are straightforward.
Shared customer and job
Does the certificate and the invoice attach to the same customer, so nothing is typed twice?
Native invoicing
Is invoicing built in, or a beta add on that still needs a separate accounting tool?
Works offline
Can you complete an EICR with no signal, or does the app stop until you reconnect?
Gets you paid
Can the app chase unpaid invoices and take payment, not just produce the document?
If you also carry out portable appliance testing, our guide to the best PAT testing software and apps covers that certificate specifically.

Frequently asked questions
What is the best all-in-one app for electricians in 2026?
The right choice depends on your size and how much you work in signal dead areas. Checker suits electricians who want native electrical certificates, invoicing, chasing and on site card payment in one offline capable app from £10.99 a month plus VAT. Tradify pairs certificates with strong invoicing but has no offline mode. Commusoft and Joblogic suit larger, multi engineer firms, while iCertifi is certificate first with no native invoicing.
Which apps do electrical certificates and invoicing in the same tool?
Checker, Tradify, Powered Now, Commusoft and Joblogic all keep electrical certificates and invoicing within one platform. iCertifi is the exception here: it is strong on certificates but has no native invoicing beyond a beta add on, so it usually needs a separate billing tool alongside it.
Can I turn an EICR into an invoice without typing it twice?
In a true all-in-one, yes. Because the certificate and the invoice attach to the same customer and job, completing an EICR in Checker lets you raise the invoice against that same record without re-keying the customer or the job details, and the app can chase the invoice automatically if it goes unpaid.
Do I need offline working as an electrician?
If you carry out inspections in basements, plant rooms, new builds without power or rural properties, offline working matters, because those are exactly the places signal disappears. Checker, Powered Now, Commusoft and Joblogic all confirm offline working with a sync on reconnect, while Tradify states it has no offline mode.
How much does an all-in-one electrician app cost?
Prices vary by model. Checker starts from £10.99 a month per sub-user plus VAT with no lock-in. Powered Now runs £28 to £40 per user per month excluding VAT, Tradify £34 to £44 per user per month, and Joblogic £45 per user per month billed annually. Commusoft is quote only and aimed at teams of six or more, and iCertifi is priced per app, from around £14.99 a month for the entry level Fire Safe app up to around £25.99 for individual trade apps such as GasCert.
