Managed file transfer for small business: pricing compared

The short version

• Managed file transfer is priced on three dials: per user or per credential, per gigabyte of storage or transfer, and the minimum monthly ticket. Small teams get hurt by the first and the third, not the second.
• Verified October 2026 entry prices: Couchdrop Link at $50 per month for one user and 10 GB of monthly data, SFTP To Go Launch at $150 per month for 20 credentials and 100 GiB, Files.com Starter at $199 per month for 10 full users.
• For a five-partner exchange holding 100 GB, that is $150 to $199 per month on the commercial services. The same workload on managed SFTPGo hosting at DANIAN is about €44 per month, with unlimited users.
• The engine underneath does not have to be proprietary. SFTPGo, the open-source transfer server, covers the protocols and storage backends; the choice is only who runs it. Our full cost comparison of running SFTPGo prices every path.

What you are actually paying for

Every managed file transfer bill is assembled from the same three components. Understanding them is the whole game, because vendors weight them differently and your workload decides which weighting punishes you.

The first dial is the headcount fee. Some services bill per user, some per credential (an SFTP login is a credential even when a human never sees it), some per connection. Five partners dropping files into five folders is five of something, and the fee lands whether those accounts move one file or ten thousand.

The second dial is the data meter: included gigabytes of storage and monthly transfer, with tier upgrades or overage rates beyond them. This dial is fair by nature; data has a cost, and metering it honestly is reasonable.

The third dial is the minimum ticket: the price of the cheapest plan that can legally face the internet with your logo on it. This dial is what quietly excludes small teams from the market, because a $150 floor is a real budget line for a five-person shop and pocket change for a corporation.

The market, priced (October 2026)

These are the displayed prices on each vendor's own pricing page, verified in the same week this article was published. Prices move; check the sources at the bottom before you sign anything.

Read the Couchdrop line carefully, because it is the purest example of the headcount dial in the market: fifty dollars a month buys exactly one SFTP user and ten gigabytes. The moment a second partner needs a login, you are in contact-sales territory with no published price.

The math for a real small-business workload

Two scenarios, run honestly. Scenario A: a five-partner file exchange holding 100 GB, moving under 200 GB a month. Scenario B: the same exchange grown to 500 GB stored and 500 GB a month.

At the small workload the flat-price lane is a quarter of the commercial ticket. At half a terabyte the gap narrows on storage (metered gigabytes are gigabytes) but the DANIAN column still carries unlimited users, while the $325 Scale plan is anchored to 50 credentials and the $199 Starter to 10 users. Add three more partners mid-year and the commercial columns move; the flat column does not.

Where each model breaks

SFTP To Go's model breaks on storage and bandwidth walls: the tier jump from Launch to Scale is more than double the bill, and the caps are hard limits, not soft ones. Couchdrop's model breaks on the second user: Link is a one-connection product by design, and everything above it is unlisted pricing, which for a small business usually means the quote starts high. Files.com's model breaks on headcount: it is a full enterprise platform priced per full user, and paying for a suite when you need an SFTP drop zone is buying a truck to carry a letter.

The metered flat-price model breaks differently, and honestly: if you hold multiple terabytes, per-GB storage metering catches up with tier pricing, and at some scale the commercial platforms bundle enough storage that the arithmetic flips. Below roughly a terabyte, it does not. The break-even is knowable, published, and driven by your data volume rather than your team size.

The engine question: proprietary versus open source

None of this is about transfer technology. SFTP, FTPS, and the web client experience are table stakes, and the strongest open-source transfer server, SFTPGo, delivers the full protocol set, cloud storage backends, a web admin, and an API with no license fee at all. We profiled it in full: open-source SFTP servers in 2026.

The commercial services above are, at their core, somebody else running an engine and charging by their three dials. The managed-SFTPGo lane runs the same class of engine as a managed service: your instance, your data, your users, in your choice of 21 datacenter regions, at a flat €9 a month plus metered storage. If your requirement is partner and supplier exchange rather than enterprise EDI choreography, it is the same job at a different price structure.

Operational questions, from setting up partner drop zones to migrating from an existing SFTP server, are answered step by step in the knowledge base.

Who should pick what

Pick Files.com if you genuinely need an enterprise file platform: compliance bundles, deep integrations, a vendor suite behind it, and the budget to match. Pick SFTP To Go if you live in a SaaS ecosystem and want SFTP-as-a-service with hard, predictable caps. Pick Couchdrop Link for exactly what it is: a single connection, cheap, no more. Pick the managed-SFTPGo lane if your problem is partners and suppliers exchanging files with your business, you want the pricing to scale with data rather than people, and you want a human to answer when something breaks. The managed SFTPGo hosting page starts a 7-day trial without a card.

Frequently asked questions

How much does managed file transfer cost?
Commercial entry tickets verified in October 2026: Couchdrop Link $50/mo for one user and 10 GB of monthly data, SFTP To Go Launch $150/mo for 20 credentials and 100 GiB, Files.com Starter $199/mo for 10 full users. A managed open-source alternative exists at €9/mo flat with unlimited users and metered storage beyond 30 included GB.

Why is managed file transfer so expensive for small teams?
Because the pricing model was built for enterprises. Per-user and per-credential fees scale with your partner count, and minimum tickets of $150 to $199 assume a corporate budget. A small team with five partners pays the same floor as a hundred-person department, which is why flat-price models with data metering fit smaller workloads better.

What is per-credential SFTP pricing?
Billing by login rather than by person. A credential is one SFTP or FTPS login, whether it belongs to a human partner or an automated integration. SFTP To Go's Launch plan, for example, includes 20 credentials; needing a 21st moves you to the next tier.

How much does SFTP To Go cost?
Verified October 2026: Launch at $150 per month (or $1,800 per year) with 20 credentials, 100 GiB storage, and 200 GiB monthly bandwidth; Scale at $325 per month with 50 credentials and 500 GiB each of storage and bandwidth; Enterprise is custom-priced.

How much does Couchdrop cost?
The published plan is Link at $50 per month, covering one SFTP or FTP user, one mailbox, and up to 10 GB of data per month. The Essentials, Business, and Enterprise tiers above it are contact-sales with no public pricing.

How much does Files.com cost?
Starter is $199 per month, or $2,099 per year, with 10 full users and 50 system users included; additional users are billed individually. Higher tiers add compliance and enterprise capabilities at increasing price points.

Is there a flat-rate managed file transfer service?
Yes. Managed SFTPGo hosting on DANIAN is €9 per month flat per instance with unlimited users, 30 GB of storage and 1 TB of bandwidth included, and transparent metering (€0.50 per GB storage, €0.03 per GB bandwidth) beyond the included amounts. Backups, updates, monitoring, and support are included.

What counts as a user in file transfer pricing?
It depends on the vendor, and the differences matter: some count human administrators, some count every SFTP login, some count partner accounts, and Files.com distinguishes full users from system users. Read the definition before comparing prices, because two services at the same dollar figure can bill very different populations.

Do managed SFTP services charge for bandwidth?
Most include a monthly transfer allowance and charge or force a tier upgrade beyond it. SFTP To Go's Launch includes 200 GiB of monthly bandwidth with its 100 GiB of storage; the DANIAN plan includes 1 TB of monthly bandwidth with bandwidth beyond it at €0.03 per GB.

What happens when I exceed the included storage?
On the commercial plans you typically hit a hard cap and must upgrade the tier. On the DANIAN managed plan there is no wall: storage beyond the included 30 GB is metered at €0.50 per GB on the same invoice, so a slow month and a big month price themselves without a plan change.

Can I get managed file transfer with unlimited users?
Yes. The DANIAN managed SFTPGo plan bills per instance, not per person: five users or fifty pay the same €9 base. Most commercial services bill per user or per credential, which is exactly the dial that grows your bill as you add partners.

Is open-source file transfer software production-ready?
The leading open-source transfer server, SFTPGo, serves SFTP, FTPS, WebDAV, and HTTPS from one process with cloud storage backends, a web admin, and an API, and has been maintained since 2019 by a member of the Go team. Production readiness is a function of operations, not license: either you run it, or a managed provider does.

How do I move off a per-user SFTP service?
The mechanics are simple: recreate users and folders on the new server, move the data, and repoint partners to the new host, ideally one partner at a time. A step-by-step migration guide, including legacy FTP moves, is in the SFTPGo knowledge base, and managed-plan support assists with migrations.

What should a five-partner file exchange cost?
With 100 GB of stored data, the honest verified range is $150 to $199 per month on the commercial per-user services versus roughly €44 per month on flat-price managed SFTPGo with unlimited users. Under a terabyte of data, pricing that scales with data rather than headcount wins on arithmetic.

Are per-GB storage fees a bad thing?
No, and that is the honest part of the market: data has a real cost, and metering it is fair pricing. The fees that punish small teams are per-user charges and high minimum tickets, because those scale with your partner count and your existence rather than your usage.
