The testing takes a day. The paperwork takes the week.

PATKeeper takes the file straight off your tester and turns it into organised clients, asset histories, branded certificates, a retest calendar and a live portal your customers can check themselves.

100,000 credits for your first month, so your whole back catalogue comes in free.

The PATKeeper test register, showing a client's assets with pass and fail results, filters and totals.
One client's whole register — every asset, every test, filtered how you like.
Who it's for

Built for the people doing the testing.

Written by a technical manager who was running 800 events a year off a spreadsheet, for anyone still doing the same.

🔌

Sole traders & small contractors

You do the testing, the certificates, the chasing and the invoicing. PATKeeper takes the middle two off your hands.

  • Certificates out the same day
  • Every client's history in one place
  • Nothing to install, works on the van laptop
🏛️

Venues, schools & estates teams

Thousands of assets, several buildings, and an inspector who wants proof. Know what's due before someone asks.

  • Retest calendar across every location
  • Asset histories going back years
  • Notes and photos that stay with the asset
🧰

Testing firms with crew

More than one engineer, more than one tester, and a pile of files at the end of the week.

  • Import from any tester or spreadsheet
  • Duplicate-safe — import the same file twice safely
  • Clients check their own records instead of ringing you
Why bother

The job doesn't end when the tester beeps.

Everything here exists because it was a Sunday-evening job first.

01 Get your evenings back

Upload the file, check the preview, generate the certificate. What used to be an evening of copy-and-paste is a few minutes.

02 Never miss a retest

Every client's next visit is worked out for you and laid out on a calendar. Drag a job to move it; the whole visit moves with it.

03 Stop fielding "can you send that again"

Each client gets a live link to their own records. They look it up themselves, and it's still right months later.

04 Prove it when it matters

Complete history for every asset, with the failures written out in plain English rather than a bare code.

05 Import the same file twice, safely

PATKeeper recognises what it already holds. Duplicates are skipped, flagged in the preview, and never cost you a credit.

06 Your data stays yours

Export back to CSV or a tester-readable file whenever you like — whole history or just the current state of the register.

What it does

Everything after the test, sorted.

Import

From any tester — or any spreadsheet

Megger .DB files go straight in. So do CSV and Excel exports from anything else, with a matching step that reads your column headings and works out where everything goes.

  • Sample rows from your own file, so you can see it's lined up right
  • Anything it can't place is left for you rather than guessed at
  • A preview showing exactly what's new before anything is saved
  • Manual entry wizard when you're working without a downloadable tester
The column matching step, showing spreadsheet columns beside sample data and the PATKeeper field each one will be imported as.
Your columns, your data, and where each one is going.
Schedule

A calendar that knows when everyone's due

Every asset you hold is placed on a calendar from its last test and the client's retest interval. See a year at a glance, a month in detail, or a running list of what's coming.

  • Whole visits, not individual assets — a four-day job reads as one job
  • Drag a job to a new date and the whole visit moves
  • Overdue, due-soon and scheduled colour-coded throughout
  • Set a retest interval per client — they're not all annual
The retest calendar in month view, with client jobs shown as bars spanning the days they are due.
Jobs, not a wall of individual assets.
Paperwork

Certificates that explain themselves

Branded with your logo and your client's. Failures written out in plain English, photos attached where you took them, and a QR code linking back to the live records.

  • Summary reports, certificate packs and asset registers
  • Your abbreviations translated for the reader, never in your data
  • QR code on the cover for clients who've got a printed copy
  • Save reports against the client so you can find them again

Client portal

Your clients, checking their own records

Send a link. They see their assets, test history and documents — live, read-only, with nothing to install and no password to forget.

  • Shows when their next test is due, and how long it usually takes
  • They can suggest a date; you confirm it and it lands in your calendar
  • Their own certificates and documents, always current
  • Revoke the link any time
The client portal showing a client's totals, when their next test is due, and a button to suggest a date.
What your client sees. No account required.

Tools for the person holding the tester

Scan the barcode on a sticker and the asset's full history opens. Leave a note for whoever tests it next — even for an asset that's never been tested.

  • Barcode scanning from your phone, on the same account
  • Notes and photos that stay with the asset
  • Notes that wait and attach themselves at the next import
  • Find unused asset numbers without scrolling a list
An asset's full test history with a technician's note and photo attached.
Every test that asset has ever had, in one place.
The only thing you pay for

One credit. One test record.

No per-client fees, no per-asset fees, no seat pricing. A credit is spent when a test record is saved — and nothing else costs anything.

300 credits

Importing 300 tests

A day's testing off your tester, straight in. Every record that lands in your account uses one credit.

Costs nothing

Duplicates you re-import

Import the same file twice and PATKeeper recognises what it already holds. Skipped records never use a credit.

Costs nothing

Everything after that

Certificates, reports, client portals, the calendar, asset histories, barcode scanning. Unlimited on every plan.

Questions

Frequently asked

What exactly is a test credit?

One credit covers one test record saved to your account. Import 300 tests from your tester and that's 300 credits. If you re-import a file you've already brought in, PATKeeper recognises the records it already holds and skips them — those cost nothing.

Which testers does it work with?

PATKeeper reads the .DB files Megger testers produce, and CSV or Excel exports from most other makes. If your file has its own column layout, the matching step lets you say which column is which. You can also enter tests by hand with a guided wizard.

What happens when I first sign up?

You get 100,000 credits for your first month, so you can bring your existing history across — years of spreadsheets and old tester files — without it eating into a monthly allowance. After the first month you're on your plan's normal monthly credits.

Do my clients need an account?

No. Each client gets a private link to a read-only portal showing their own assets, test history and documents. Nothing to install, no password, and it stays up to date after you've left site. You can revoke a link at any time.

Does it work on a phone or tablet?

Yes — it's a website, so there's nothing to install. Scanning an asset barcode uses your phone's camera, and your records are the same whichever device you're on.

Is my data locked into PATKeeper?

No. You can export back out to CSV or to a tester-readable .DB file whenever you like, choosing which clients and locations to include, and whether you want the full history or just the latest test for each asset.

Who's behind it?

PATKeeper is built by a working technical manager responsible for testing at a busy arts venue — around 800 events a year across several spaces. Every feature started as something that was taking too long to do by hand.
