The job
Replace the WhatsApp folder
A site manager should be able to answer “can they start Monday?” without scrolling a chat. SubbiePack is that list, plus the files behind it. Walk through it once; the app is where the work happens.
-
Create a firm account
Company name, work email, password. No OAuth in version one. One firm per login to start. Your subcontractors are not shown to anyone else. Sign up lives on the app, not this website.
-
Pay for the firm, then add people
One plan: £29 a month. Without a subscription you cannot add subcontractors. Status changes only when Stripe’s webhook says so — a success page does not mark you paid.
Then add the people on the job: name, trade and phone. Work email is optional. Archive someone when they leave; do not mix firms.
-
Put the current file on each one
Public liability, CSCS and RAMS are required to be in date. Employers’ liability is optional — not every sole trader has it. Each file needs an expiry (DD/MM/YYYY). PDF or photo. One current file per type.
-
Read the list before they arrive
The paid homepage is who can go on site. Blocked (expired or missing required files). Expiring within your reminder window. In date. Mobile list. Tap through to the subbie and the file.

Ask them for the file, if you still do not have it
Send a single-use link that lasts 7 days, for one subbie and one document type. They open it on a phone, upload, type the expiry. They do not need an account. You see waiting versus uploaded.

Northside Contracts asked M. Osei Groundworks to send this file from a phone. No account needed.

Reminders go to the firm, not the chat
Email the firm at 30, 14 and 7 days, and on the day a file expires. Set those windows in settings. Every reminder is logged. Copy is plain UK — no “certificate invalid”. There is no WhatsApp send in version one.
-
Optional sites, and a ZIP pack if you need to send files on
A site is a name plus an optional address line. Assign subbies. See who can start on that job (all required files in date) versus who cannot. Download a ZIP of current in-date files for sending on. The pack is not a certificate.

Extra office login, then take your data with you
The owner can invite one office or site manager by email. Same data, no extra billing. The owner can revoke.
GDPR: export the firm (JSON/ZIP) or delete the firm and all files, from the app. We keep name, trade, phone, optional work email, and the files you choose. Not National Insurance numbers, dates of birth or home addresses.
Dates are the ones you type. Files are the ones you upload. SubbiePack does not check CSCS with CITB, talk to insurers, or say a document is genuine.
