Briefs, quotes, projects, invoices, and a client portal your clients will actually use. Built for service businesses in the UK.
Sound familiar?
Clients describe projects across 6 different email threads, a voice message, and a PDF from 2022. Nothing is in one place.
You build quotes in a spreadsheet, email them, then manually update three times when the scope changes. No paper trail.
Clients message you every few days for updates because there's nowhere for them to see progress. You end up being the project tracker.
There's a better way.
No onboarding call required. Set up your business, invite your team, and start managing projects the same day.
Share your branded brief link. Clients fill in their project details — no account needed.
Create a professional quote with line items, VAT, and deposit terms. Send it in one click.
Upload deliverables to the client portal. They review, leave feedback, and sign off — without endless back-and-forth.
Send a polished invoice with your payment details or a payment link. Track what's paid and what isn't.
Every service business hits this wall. The tools that got you started can't keep up. Client details live in five places, invoices get lost, and your team coordinates through a chat group that's 3,000 messages deep.
Your clients see progress, approve work, and sign off — without the usual back-and-forth. Branded with your logo and colours.
Professional quotes with VAT, deposits, and payment terms. Send invoices that get paid. Track everything in one place.
Invite your team. Bring in freelancers on specific projects. Everyone sees what they need, nothing more.
Share your portal link on social media, in your email signature, or on your website. Clients submit briefs, approve quotes, review deliverables, and pay — all in one place. One link instead of five scattered tools.
One link for Instagram, TikTok, LinkedIn, or anywhere you promote your services. Clients click once and land on your branded portal.
Add a "Work With Me" or "Submit a Brief" button to your website — just link it to your Kestern portal. Works on any website. Just paste your link.
Put your portal link in every email. Every new contact can submit a brief, get a quote, and pay — without you lifting a finger.
Your clients don't need an account. Each project gets its own private, secure link. They click once and they're in — no passwords, no friction.
Replace the 5 tools you're juggling with one link.
Send clients to your Kestern portal — one link where they can submit a brief, see quotes, track progress, approve deliverables, and pay. That's it.
Simple plans that scale with you. Cancel anytime. No setup fees.
Perfect for solo operators just getting started. Everything you need to look professional from day one.
For growing teams managing multiple clients and projects at once. Bring your crew in and keep everyone aligned.
For established businesses that need the full Kestern experience — team, collaboration, and the ability to work with partner businesses.
For agencies scaling up — unlimited clients, white-label portals, sub-contracting workflows, and full API access.
