You signed up for DocuSign three years ago to close one deal. You've used it twice this quarter. The renewal invoice just landed and it's £40 a month — or worse, you're still on the Personal plan and you just hit the five-envelope monthly cap on the morning you needed to send a contract out. This is the moment most people start hunting for an alternative. Below is the case for Flint — what we do differently, what we deliberately don't do, and how to decide whether to switch.
Why DocuSign earned its position
Let's not pretend DocuSign is the bad guy here. It became the default because it solved a real problem at exactly the right time, and twenty-plus years later the product is genuinely good at what it does. Three things in particular it nailed:
- An audit trail recipients trust on sight. The DocuSign certificate of completion is recognisable to anyone who's ever signed a commercial agreement. That instant familiarity has real value when the document needs to go in front of a lawyer or auditor.
- Multi-party orchestration that actually works. Sequential signing orders, conditional routing, reminders, delegation — DocuSign handles complex sign-off chains reliably. For a sales team running hundreds of envelopes a month, that infrastructure matters.
- Deep integration with the systems sales teams already use. Salesforce, HubSpot, Workday, dozens of others. Templated agreements that auto-populate from CRM records. If your job involves living inside that stack, DocuSign earns its seat.
If you're in that bucket — running structured signature programs, deeply integrated with enterprise tooling, sending envelopes by the hundred — DocuSign is the right answer. Keep it.
What Flint matches, and where
The headline: Flint produces electronic signatures with the same legal standing as DocuSign's. Both rely on the intent-based, audit-trailed e-signature model recognised under the ESIGN Act in the US, eIDAS in the EU, and the UK Electronic Communications Act. There is no legal hierarchy where DocuSign signatures outrank Flint signatures. A signed contract is a signed contract.
Concretely, here's what carries across:
- Audit trail. Timestamp (UTC plus signer-local time), email address, IP address, user-agent string, and a SHA-256 hash of the document captured at the moment of signing. Appended as a final page to the PDF and stored server-side as a tamper-evident record. The same evidential ingredients DocuSign records.
- Multi-party signing. Drop a signature box per recipient, type their email, and each gets a unique tokenised link that walks them through the signing flow. The links are single-use and tied to the recipient's email — passing the link sideways doesn't give a third party signing rights.
- Three ways to sign. Draw on a trackpad or touchscreen, type with a handwriting font, or upload a transparent PNG of an existing scanned signature. Recipients get the same three options when their link opens.
- Reminders and chase notifications. If a recipient hasn't signed after a few days, Flint sends a gentle nudge. You can re-send the link manually from the document dashboard at any time.
- Document storage. Signed PDFs land in your private Flint library alongside the audit trail. Search, re-download, share again.
How signing in Flint actually works
Two flows, depending on who needs to sign. If it's just you, the path is direct. If you need counter-signatures, you switch modes and Flint handles the routing.

The pricing argument, honestly
DocuSign's Personal plan starts around £10/month for five envelopes. The Standard plan jumps to roughly £35/month per user for unlimited sending. Real Estate, Business Pro, and Advanced Solutions tiers climb from there, often via a sales rep rather than self-service. The model rewards predictable, high-volume signing.
Flint Pro sits at a flat subscription that unlocks every tool on the site — sign, compress, merge, redact, edit, convert, password-protect, the lot — with no envelope cap, no per-signer charge, no premium upsell for the audit trail. If you spend thirty seconds a week looking at PDFs and your sending volume is sub-100 envelopes a month, the maths is straightforward.
Where DocuSign still wins
Trying to claim otherwise would be silly. Three areas where DocuSign is genuinely a better tool:
- Salesforce / HubSpot / Workday integrations. Flint doesn't plug into CRMs. If your contracts are generated from CRM templates and need to flow back into the opportunity record on completion, DocuSign's integration surface is unmatched. We don't pretend to compete here.
- Templating at scale. Reusable templates with conditional fields, role-based signer slots, and bulk envelope sends are core DocuSign functionality. Flint supports re-using documents, but not the full templating machinery a sales-ops function relies on.
- Qualified Electronic Signatures. If you specifically need an eIDAS QES with a certificate from a trust-service provider, DocuSign offers that tier and Flint doesn't. The vast majority of commercial documents don't require it — but a small slice do, and that slice stays with DocuSign or Adobe.
The wider alternatives landscape
Flint isn't the only DocuSign alternative. A quick orientation in case we're not the right fit:
HelloSign (now Dropbox Sign)
Cleanest competitor to DocuSign on user experience. Similar pricing, similar feature surface. If Dropbox is already central to your workflow, it's a natural choice. Pricing is also per-user/per-month though, with envelope caps on the lower tiers.
Adobe Sign
Pairs well with the rest of the Adobe Document Cloud. If your team is already on Acrobat Pro DC, Adobe Sign comes either bundled or at a steep discount. Strong in enterprise, similar pricing posture to DocuSign at the team tier.
PandaDoc
More than a signing tool — it's a quote/contract authoring platform with signing tacked on. Excellent if your bottleneck is actually drafting the proposal, not signing it. Overkill if all you need is a signature on a PDF someone else sent you.
Flint
Browser-based, no install, flat monthly pricing, no per-envelope billing, audit trail built in, every other PDF tool sitting alongside it. The sweet spot is the “I sign things regularly but I'm not running a sales floor” use case — solo operators, small teams, professional services.
The bit DocuSign doesn't do
DocuSign signs things. That's the product. If the document also needs to be compressed before email, merged with an amendment, redacted before circulating to a wider audience, or locked with a password, you're reaching for a different tool. Flint sits beside the signing flow:
- Compress PDF when the signed contract is too heavy for an email attachment.
- Merge PDF to combine signed counterparts and the original into one archive file.
- Redact PDF to strip confidential figures before sharing the contract with a wider audience.
- Password Protect PDF to encrypt the signed file before it leaves your inbox.
- Annotate PDF if a reviewer wants to mark up the draft before it's signed.
Switching: the practical bit
No data migration is required. Your DocuSign envelopes stay in DocuSign — fully-executed contracts remain valid records regardless of which platform produced them. To start new work in Flint, you just stop sending new envelopes through DocuSign and start sending them through Sign PDF. Cancel the DocuSign subscription at renewal once you're comfortable.
One caveat: if your existing recipients are conditioned to expect a DocuSign-branded email, they may pause when a Flint email lands instead. A one-line heads-up in your initial communication (“I'll send this via Flint, you'll get a signing link from noreply@flintpdf.com”) prevents the request landing in spam.
DocuSign alternative: frequently asked questions
Is a Flint signature as legally binding as a DocuSign one?
Yes. Both produce electronic signatures under the same legal frameworks (ESIGN Act, UETA, eIDAS, UK Electronic Communications Act). Neither produces certificate-based signatures unless you specifically pay for that tier in DocuSign's case. For almost every commercial document, the two are legally interchangeable.
Will my counterparties recognise it?
The signing experience is unambiguous — recipients open a tokenised link, see the document, sign in the browser. The finished PDF carries a clearly-labelled audit trail page. In a decade of working with electronic signatures we've not encountered a counterparty rejecting a properly-audited e-signature on grounds of branding.
Is there a free tier?
You can sign documents in your browser for free. Downloading the signed result and sending requests to others requires Flint Pro — a flat monthly subscription rather than per-envelope pricing. Recipients of your signature requests never need to pay anything.
Can I use Flint and DocuSign in parallel?
Of course. Many users keep DocuSign for high-volume sales contracts and use Flint for everything else (NDAs, supplier agreements, internal sign-offs, the occasional ad-hoc document). There's no lock-in either direction.
Does Flint support signing orders?
Yes. When sending a multi-party request, you can specify sequential signing — recipient B doesn't receive their link until recipient A has signed. Parallel signing (everyone gets the link at once) is the default.
How long are signed documents stored?
Indefinitely, while your Flint account is active. They sit in your document library with the audit trail attached. You can re-download or share them at any time.
What about EU eIDAS Qualified Electronic Signatures?
Flint doesn't issue QES — these require certificates from a trust-service provider on the EU Trusted List, which is a narrower offering. If your specific use case names QES (some public-sector procurement, certain regulated industries), you'll want a specialist provider. Standard contracts, proposals, NDAs, and offer letters don't require QES — the electronic signature Flint produces is legally sufficient.
Is there an API?
Not currently. If you need programmatic envelope creation as part of a back-end workflow, DocuSign or Adobe Sign are still the appropriate choices. Flint is browser-first.
