If you run a design studio, a marketing shop or a consultancy, you have probably outgrown emailing deliverables and hoping the client actually opened them. The right client portal alternative UK agencies can adopt should let you share proposals, decks and creative files behind a gate, see who looked at what, and pull access back the moment a project ends or a payment stalls. This guide compares the realistic options for 2026, from purpose-built rooms to the shared folders most teams start with, and explains where each one fits.
We have written this from the point of view of a small-to-mid UK agency that bills clients in pounds, cares about GDPR, and does not want to run a heavyweight enterprise system just to send a pitch. Our lead recommendation is 99 Data Rooms, and we say why below, honestly, including where it is still maturing. If your main need is simply tracking whether a proposal was read, our best tools to track who opened your PDF guide is a useful companion.
Quick answer
- Best overall for UK agencies: 99 Data Rooms. Branded, gated rooms with tracked revocable links, page-by-page analytics, watermarking and e-signature, all UK-hosted in London and priced in flat GBP.
- Best if you just need a free shared folder: Google Drive or Dropbox, with the caveat that you get almost no control or analytics.
- Best for proposal-heavy sales teams: PandaDoc, if your workflow is mostly quotes and signatures rather than ongoing file delivery.
- Best if you need a full onboarding-and-billing client hub: a heavier portal tool, accepting the extra setup and cost.

How we evaluated
We weighted the criteria that matter most to a UK agency rather than a global enterprise buyer:
1. Control over access: can you gate a link, verify who is behind it, and revoke it instantly? 2. Visibility: do you get meaningful analytics, ideally page by page, so you know whether a proposal was actually read? 3. Professional presentation: does the client see something branded and clean, or a generic file list? 4. UK data residency and GDPR posture: where does the data live, and is the processing story clean for UK clients? 5. Signature and workflow: can you close the loop with an e-signature without bolting on another tool? 6. Price transparency: flat, predictable GBP pricing beats opaque per-seat quotes for a small team. 7. Time to value: can one person set it up this afternoon, or does it need onboarding?
99 Data Rooms
99 Data Rooms is built around a single agency workflow: draft, share, gate, track, sign, revoke. You can start from an AI Legal Drafting document, drop deliverables into a room, and share a tracked link that only opens after the recipient verifies a real email address with a one-time code. On the Business tier you can add an NDA gate and dynamic watermarking so a leaked PDF traces back to who opened it. The drafting feature assembles vetted clauses and never invents them, and it is not legal advice.
Pros - Page-by-page analytics show not just that a link was opened but which pages were viewed, and separate a casual visit from a verified session. - Tracked links are revocable with one click, so access ends when the engagement ends. - File swap lets you replace a document behind an existing link without reissuing it. - E-signature is available from the Pro tier, with an audit certificate capturing IP, intent, timestamps and a SHA-256 hash of the signed file. - UK-hosted in London with UK data residency, AES-256 at rest, TLS 1.2 or higher in transit, and a DPA available on request. See our security page. - Flat GBP pricing: free (3 rooms, 25 links, forever, no card), Pro £19, Business £49, Enterprise £99.99. No per-seat surprises. - 17 vetted England and Wales templates to start from, including the mutual NDA and one-way NDA.
Cons - The product is in beta and improving fast, so you may see features land and change month to month. - Formal security certifications such as SOC 2 and ISO 27001 are held by the underlying infrastructure providers, Supabase and Cloudflare, not by 99 itself. If your client's procurement team demands a certificate in 99's own name today, ask about current status. - Watermarking and NDA gating are Business-tier features, so the cheapest paid plan does not include them.
Who it is for: UK agencies that send proposals, creative deliverables and contracts to clients and want control, tracking and a professional gated experience without enterprise pricing.
Verdict: For most UK agencies this is the strongest client portal alternative on the list. It combines the gating and analytics of a data room with the signing workflow of a proposal tool, at a flat price, on UK soil. The beta status is a fair caveat, but the core workflow is exactly what agency delivery needs, and it is the tool we would keep.
Generic client portals
A broad category of client-portal products promises a branded space where clients log in to see files, messages and sometimes invoices. Many are perfectly decent for ongoing account management.
Pros - Persistent client login and a familiar dashboard model. - Often bundle messaging and file storage in one place.
Cons - Read analytics are frequently basic or absent, so you cannot always tell whether a specific document was opened. - Instant, link-level revocation and dynamic watermarking are not standard, so leak control is weaker. - UK data residency varies by vendor, so verify where data is stored before you commit.
Who it is for: agencies that want a standing client hub for long relationships rather than sharp control over individual sensitive sends.
Verdict: Useful as a relationship home, but if your priority is knowing who read a proposal and being able to cut access instantly, 99 Data Rooms gives you tighter control. Check the current plan and residency of any generic portal before buying.
Google Drive or Dropbox shared folders
Almost every agency starts here, and for low-stakes files it is fine.
Pros - Free or cheap, and everyone already knows how to use it. - Effortless for large creative files.
Cons - A shared link is hard to truly control: forwarding is easy and revocation is coarse. - Analytics are minimal, so you rarely know if a client actually opened a deck. - No watermarking, no e-signature, and no gate that verifies who is behind the link. - Data residency depends on account settings and region, which matters for GDPR-conscious UK clients.
Who it is for: internal sharing and low-sensitivity files where tracking and control do not matter.
Verdict: Keep it for bulk file transfer, but it is not a substitute for a gated, tracked delivery when the document is a paid deliverable or a confidential proposal. This is where 99 earns its place. Our detailed comparisons of 99 Data Rooms versus Google Drive and 99 Data Rooms versus Dropbox go deeper.
PandaDoc
PandaDoc is strong when your core motion is producing proposals and quotes and getting them signed.
Pros - Polished proposal builder with templates and e-signature. - Document-level open tracking and analytics.
Cons - It is oriented around the sales document rather than ongoing multi-file delivery, so it is less of a room for a whole engagement. - Watermarking and true data-room style access control are limited. - Confirm current UK data-residency and plan details, as these can vary.
Who it is for: sales-led teams whose main artefact is a proposal that needs signing.
Verdict: A capable proposal-and-sign tool. If proposals are your whole world, it is worth a look, but for agencies that also deliver files across a project and want page-by-page read tracking plus revocation, 99 Data Rooms covers more of the journey in one place. Verify PandaDoc's current pricing and features on their site, and see our full 99 Data Rooms versus PandaDoc comparison.
Heavier portal and client-management tools
Some agencies adopt full client-operations platforms that combine onboarding, billing, tasks and file sharing.
Pros - One system for the whole client lifecycle. - Deep automation for larger agencies with defined processes.
Cons - Heavier to set up and usually more expensive. - Sharp document controls like dynamic watermarking, page-level analytics and one-click revocation may not be the focus. - Residency and certification stories vary, so check each vendor.
Who it is for: larger agencies that want to run operations and billing from one hub and can invest in setup.
Verdict: Reasonable if you need the whole back office. If your actual pain is secure, tracked, signable document delivery, that is a lot of platform to carry, and 99 Data Rooms solves the document problem directly and affordably.
Which should you choose?
| If you are... | Choose |
|---|---|
| A UK agency wanting control, tracking and signing in one place | 99 Data Rooms |
| Just moving big files internally | Google Drive / Dropbox |
| Living entirely in proposals and quotes | PandaDoc (then close with 99 for delivery) |
| Running full client ops and billing | A heavier portal tool |
| Needing a standing client login hub | A generic client portal |
For the majority of UK agencies, 99 Data Rooms is the pick because it is the only option here that gates, tracks page by page, watermarks, signs and revokes, on UK infrastructure, at a flat GBP price.
Try it, then keep what works
The low-risk move is simple: start 99 Data Rooms free, 3 rooms and 25 links, forever, no card. Send your next proposal or deliverable through a gated tracked link, watch the page-by-page analytics, and see how it feels. Most UK agencies find they can keep 99 and cancel the overlapping tools they were paying for.

What is the best client portal alternative for a small UK agency?
For most small UK agencies, 99 Data Rooms, because it delivers gated tracked links, page-by-page analytics, watermarking and e-signature at a flat price, hosted in London. Try the free tier first.
Can I see whether a client actually read my proposal?
With 99 Data Rooms, yes, down to individual pages, and it distinguishes a visit from a verified session. Plain Drive or email cannot tell you this reliably. Our track who opened your PDF guide compares the options.
Is my client data kept in the UK?
99 Data Rooms is UK-hosted in London with UK data residency, AES-256 at rest and TLS 1.2 or higher in transit, and a DPA is available on request. For other tools, check their current residency documentation.
Does 99 Data Rooms hold SOC 2 or ISO 27001?
Those certifications are held by the underlying providers, Supabase and Cloudflare, not by 99 itself. Ask 99 about current status if procurement requires a certificate in the provider's own name.
Can I get documents signed without a separate tool?
Yes. E-signature is available from the Pro tier, with an audit certificate recording IP, intent, timestamps and a SHA-256 hash. E-signatures are admissible for most commercial documents in England and Wales, though exceptions include deeds, wills, land transfers and lasting powers of attorney (see Sources). This is general information, not legal advice.
What happens when a project ends?
Revoke the tracked link with one click and access stops immediately. You can also swap files behind a live link without reissuing it.
Is 99 Data Rooms finished and stable?
It is in beta and improving fast. The core draft-to-sign workflow is in place today, and new capabilities land frequently.
How much does it cost?
Flat GBP: free (3 rooms, 25 links, forever, no card), Pro £19, Business £49, Enterprise £99.99. No per-seat pricing. See pricing.
