Can each project have its own route?

Yes. Use a separate number per project, or route by known contact. Keep one public number for new enquiries.

Can subbies call the same number as customers?

Yes. Line recognises known numbers and sends them to the right project contact.

Can it take quote details?

Yes. Molly asks your intake questions and logs the answers. Your estimator prices it.

Can office and site see the same messages?

Yes. Everyone with access sees the same threads, notes, and assignments.

Can the whole team use one number?

Yes. Everyone gets their own login and calls or texts from the business number on their own phone. The shared inbox shows who's handling what.

How much does Line cost for builders?

Plans start at £4 a month with a UK number included. Calls, texts, and Molly's minutes are charged per use. No setup fee and no minimum term.

What does Line do for builders?: A shared number and inbox for quote enquiries, live projects, suppliers, and subcontractors. Each call goes to the person who owns it.
Can I keep my current number?: Yes. Port your UK number to Line, or start with a new one today and port later. Either way it works on the phone you already have.
What happens when I miss a call?: The caller gets a text asking whether it's a new job or an existing project, and for the postcode or site. You call back knowing which.

Give every call an owner

The site manager shouldn't field sales calls. The office shouldn't hold up an access change. Route by who's calling and why.

Qualify new work properly

Location, project type, whether there are drawings, and when they want to start. All before the first site visit.

Recognise the live projects

Clients, architects, suppliers, and subbies go through to the right person with the thread attached.

One number on the hoarding

Office and site call from the business number. Nobody's personal mobile ends up on a site board.

Set up in an afternoon

No engineer, no hardware, no contract. Three steps from sign-up to your first call.

1
Get a number
Choose a UK mobile or local number, or bring the one that's already on your van and your website.
2
Tell Line who handles what
New enquiries to estimating. Known contacts to the project owner. Suppliers to site.
3
Set what happens when you can't answer
Missed calls get a text asking for the project or the postcode. After hours, Molly or voicemail.

Builder call ownership

The project stage decides who gets the call.

When this happens	Line does this	So you get
New extension enquiry	Collects postcode, scope, design stage, and timing.	A structured lead for estimating.
Supplier calls about a delivery	Recognises the number and routes to the site contact.	The office doesn't relay time-critical detail.
Client texts an access change	Notifies the project owner in the shared thread.	The update survives the shift change.
