Oneflow Review (2026)
By Daan Haket · Tested hands-on · written with an AI assistant · who does what
The entry is €250 a month on annual billing — €3,000 a year committed before you've sent your first contract — and the rest of the ladder lives in a sales conversation. If you only need documents signed, dedicated e-sign tools start at roughly a tenth of that.
sales and legal teams with real contract volume who want the full lifecycle — creating, negotiating, e-signing and archiving interactive contracts — in one platform with CRM integrations.
you just need signatures (a per-seat e-sign tool costs a fraction), or you cannot commit to annual billing at €250 a month.

Tested by our team on 24 October 2026 during the trial, without a card, without inviting a counterparty and without sending anything for signature: Daan created the account and our AI assistant ran the test in Daan's browser. We imported a clearly fictional one-page test PDF with a known document ID, amount and dates, checked the data settings, and requested a full account export.
How we tested
- Read the trial banner and user licence label
- Imported a PDF manually and attempted Mark as signed
- Inspected the data-management integration switches
- Requested Export account with PDF contracts enabled
- Compared the returned PDF text and spreadsheet metadata with the import
- Manual import is labelled 'Imported documents are for archiving only.' (up to 50 MB). Our PDF became an 'Imported draft' with its text converted into editable content, line for line. Term and parties have to be filled in by hand.
- 'Mark as signed' answered 'Missing signatory: To mark this contract as signed, at least one participant must be a signatory.' We added no signatory, so the document stayed a draft.
- In Admin > Data management of the new account, the switches for Customer.io and OpenAI were on (with a link to OpenAI's terms), and the email provider was set to 'Postmark (US)'.
Pricing (2026)
✓ Pricing re-verified 5 Oct 2026
| Plan | Price | What you get |
|---|---|---|
| Business | €50 per user per month, billed annually (from €250 per month) | Includes 5 seats, minimum 5 users, starts at €250/month |
| Enterprise | no published price | Starts at ten users, requires sales call |
Summarised from the pricing notes below; the notes carry the conditions.
Business is €50 per user per month, billed annually, for teams starting at five users, so €250 a month is the floor. Oneflow now states that floor itself rather than leaving it to be multiplied out: the page says the entry-level plan includes 5 seats and starts at €250 per month, billed annually. That is the whole public price list. Enterprise starts at ten users and goes through a sales call, and the trial runs 14 days without a card.
A free contract-template library is available without an account. Annual is not a discount option, it is the only option, and the page now says so in its own FAQ under “Why can you only pay on an annual basis?” — the answer cites long-term value, secure deployments and dedicated onboarding. Several features sit behind a ($) marker even on the plan that lists them, meaning a paid add-on rather than an unavailable feature: eID signature on Business, redirect-after-sign on Enterprise and, read 5 October 2026, the two Beta AI features, AI Review & Insights and AI Insights Premium, on both plans.
On 18 September the Enterprise card still listed AI review and AI insights without that marker. Plans change — always verify the live price on their site.
Category context: Sales & CRM. Across the 16 tools in this category that we researched with a public US-dollar price, the median entry price is $44 a month (lowest paid plan as listed, per seat where the vendor prices per seat). Compare pricing conditions in the Software Cost Atlas →
What the price did
We capture Oneflow’s own pricing page every month and keep the figures, so this is our record of the page — not a forecast, and not someone else’s summary.
Two dated readings of the full page, no movement on price. On 18 September and 5 October 2026 oneflow.com/pricing/ read Business at €50 per user per month billed annually from five users, a stated floor of €250 a month, Enterprise on quote from ten users, and annual billing as the only option. What moved was the AI line: in September the Enterprise card listed AI review and AI insights without an add-on marker, and on 5 October both Beta AI features carried the paid add-on marker on Business and Enterprise alike.

What buyers report about Oneflow
Hands-on: tested 2026-10-24Reported by buyers: GetApp, Software Advice and B2B Reviews, read August 2026
Themes from the buyer-review sites listed at the foot of this page, read in August 2026. We tested Oneflow ourselves on 2026-10-24, but one test is a narrow sample, so here is what other buyers report. We summarise it here because the complaints are usually the part a vendor page leaves out.
- • User-based tiered pricing instead of pay-per-envelope. For anyone who has been surprised by an envelope bill, that predictability is the reason to look. (Praise as read in August 2026; the per-user tiers reviewers quoted then have since given way to an annual-only plan with a five-seat minimum, see the price section.)
- • Quick to learn, and reviewers say the real-time collaboration on a contract in progress is what they would miss.
- • Notifications and signature placement both draw complaints, as does user management.
- • Little help with migrating existing contracts — plan that work yourself.
- • Billing questions are reported as slow to resolve.
- • Customisation runs out if your workflow is unusual.
When the paid plan is worth it
Oneflow's paid tier starts at €50/user/month billed annually with a 5-user minimum, so the entry cost floor is €250/month; there is no permanent free plan, only a 14-day trial with full platform access and no credit card required. Teams that only need core contract creation, e-signature, and lifecycle tracking — without AI-assisted contract review or single sign-on — can run through the trial and then stay on this Business plan without hitting real limits.
The push toward Enterprise (custom-quoted, 10-user minimum) is narrower than it looks. Account audit logging is already on Business, and single sign-on, SCIM, custom roles, user groups, shared templates and section rules all carry the paid add-on marker there rather than being withheld, buyable without changing plan. Read 5 October 2026, only one row is blank for Business: white labelling, itself a paid add-on on Enterprise. The Beta AI review features, listed on Enterprise without an add-on marker in September, are now a paid add-on on both plans, and two newer rows, a content library and personal API tokens, come included on Enterprise and as add-ons on Business.
What upgrading does not solve is that add-on column. eID signature, SMS signature, custom email domain, batch sending, limited users, organisational units and now AI contract review are paid extras on Enterprise as on Business. So heavy eID users keep paying extra regardless of plan, and a custom quote does not fold those meters in.
Our monthly capture read this vendor's pricing page in September 2026 and again in October 2026, and the amounts were the same both times, including €50 and €250 from the pricing above. We keep watching — the registry records what moves.
What we found running Oneflow ourselves
The first findings are at the top of this page. The rest:
- The account export ticks the Excel file, users and tags by default but leaves 'PDF contracts and attachments' unticked. The download link arrived by email within half a minute, and downloading requires logging in.
- Our original PDF came back rewritten by 'MuPDF 1.28.2': 932 instead of 754 bytes and not byte-identical, with the same text. The Excel export had 9 tabs; the amount and dates were #N/A because they existed only in the document text, not in Oneflow fields.
- The trial bar counted down 14 days on the day of sign-up, after which the account drops to the free version; no card was asked.
Claim vs. what we measured
We set a claim from Oneflow's own pages next to what we saw in our test, on the plan named. The status says whether the two describe the same thing and match; it is not a verdict on the product. Confirmations are listed too.

|---|---|---|---|
| "14 days with no charge"Source: oneflow.com, read 23 Oct 2026 | Measured 2026-10-24: On the day of sign-up the app showed 'Trial ends in 14 days.

No card was asked.Our test, 24 Oct 2026; Trial | ConfirmedSame quantity: trial length shown on day one. | You get 14 days without a card; afterwards the account drops to the free version rather than closing. |
Exit test: can you take your data out?
On 24 October 2026, in the trial account from this test, we requested a full account export including PDFs and compared what came back with the test PDF we had imported, whose SHA-256 hash we had recorded beforehand. We did not re-import anything. Test date: 24 Oct 2026. We describe the friction rather than score it; this is one run with synthetic records, not a verdict on Oneflow.

Most of our reviews are researched rather than run — how we review explains which is which, and why we do not pretend otherwise.
How to actually use Oneflow
Getting real value starts with creating a trial account, then generating an API token from the Marketplace inside the app; that token goes in the x-oneflow-api-token header on every request, alongside an x-oneflow-user-email header identifying the acting user. Before sending anything through the API, a template has to already exist inside the target workspace. Contract-creation calls need both a workspace_id and a template_id. The documented failure mode is a 404 stating the template must be in the target workspace — which is what teams hit when templates were built in one workspace and the API call points at a different workspace_id.
For no-code setups, third-party integrations such as Salesforce, Zapier, and Power Automate ask for that same API token plus the account email during configuration. In practice the blocker is workspace/template alignment, not account signup.
Where this section comes from: our research notes (118 words)
oneflow.com/pricing/ and developer.oneflow.com/docs/create-a-basic-contract, read 6 Aug 2026; pricing page and the full Business-versus-Enterprise comparison table re-read 2 September 2026, where a ($) marker in a plan column means a paid add-on on that plan and not an unavailable feature. Pricing page re-read 5 October 2026 (served HTML, plan cards and comparison table): €50/user/month annual from 5 users, "Our entry-level plan includes 5 seats and starts at €250 per month, billed annually", Enterprise custom from 10 users, 14-day trial without card, annual-only and freemium FAQ unchanged; AI Review & Insights (Beta) and AI Insights Premium (Beta) ($) on both plans, content library and personal access tokens ($) on Business and included on Enterprise, white labeling ($) on Enterprise only.
Oneflow vs Signeasy, side by side
Each column shows the vendor’s own published entry price, read on the date shown. Entry prices can cover different services or units, so check what each one buys. We do not average them into a score.
Both names above are affiliate links: we may earn a commission if you sign up, at no extra cost to you. Neither changes what this table says.
The natural comparison is Signeasy — Signeasy is the lightweight per-seat e-signing route from about $10 a month; Oneflow is the full contract-lifecycle platform at €250/month annual — pick by whether you manage contracts or just sign them.
Frequently asked questions
Can you export your data from Oneflow?
Exit check 2026-10-24; route excerpt: Admin > Data management > Export account …; came along (excerpts): An Excel file (contracts.xlsx) with 9 tabs: export info, documents (35 columns), participants, data fields, products, … / Our original PDF, with the same text content / A contract PDF generated by Oneflow for the document; lost (excerpts): A byte-identical original: the PDF came back rewritten by 'MuPDF 1.28.2' (932 instead of 754 bytes, different hash) / Amount, signing date and end date as data: they exist only in the document text, so the Excel shows #N/A for them; re-import: not tested.
Does Oneflow's trial require a credit card?
Sign-up check 2026-10-24: card not requested in this account; trial length confirmed: 14 days.
What is the real entry price?
€250 a month, billed annually — €3,000 committed before you send a contract. The rate is €50 per user per month and the Business plan starts at five users, and on 18 September and again on 5 October 2026 oneflow.com/pricing/ states the floor directly: the entry-level plan includes 5 seats and starts at €250 per month, billed annually. Enterprise begins at ten users and is quote-only. If you read the €50 and stopped there, the real number is five times what you were budgeting.
Can I pay monthly, or start smaller than five seats?
Neither, and Oneflow is unusually direct about the first one. Its pricing FAQ carries the question “Why can you only pay on an annual basis?” and answers it with long-term value, secure deployments and dedicated onboarding rather than offering an alternative (read 18 September and 5 October 2026). The seat floor is stated the same way: Business starts at five users, Enterprise at ten. A 14-day trial with no credit card is the only way to use the platform without the annual commitment.
Is there a free plan?
The page contradicts itself here, and it is worth getting the answer in writing before you plan around it. The plan cards on oneflow.com/pricing/ show exactly three things on 18 September and 5 October 2026 — a 14-day trial, Business and Enterprise — and no free tier. The FAQ on the same page asks “Does Oneflow offer a freemium plan?” and answers “Yes, Oneflow offers a freemium plan”, then talks only about starting with a trial. What is unambiguously free is the contract-template library, which needs no account.
Is this a hands-on review of Oneflow?
Yes. We tested Oneflow ourselves on 2026-10-24; the section above says what we tested, what we found and what we did not test, and where a figure comes from the vendor's own documentation instead. Most of our reviews are researched rather than run; we say which is which. We name what each tool is good and bad at, and we earn a commission only if you sign up, at no cost to you.
