Partner File Gateway

Spend less time chasing and checking partner files.

Give partners one controlled place to exchange recurring files. Automate routine handoffs, reduce manual handling costs, and keep access and activity under control.

Make every exchange cost less effort

Less manual work. Lower costs. More control.

Collecting files, explaining corrections, and checking what happened all take staff time. DTO Flow gives partners and your team a shared process that reduces that overhead.

Free your team from repetitive follow-up

Partners submit and collect files through one shared portal, with clear requirements and status updates. Your team spends less time chasing attachments, answering routine questions, and coordinating the next step.

Handle more exchanges with the same team

Reuse file requirements and automate routine handoffs to reduce the work behind each exchange. Recover time for higher-value work and reduce the need for extra administration as volumes grow.

Build your business case

What could less file handling save your team?

A few minutes saved on each exchange can add up to meaningful staff capacity. Compare the value of that time with the cost of DTO Flow.

Illustrative monthly example
Recurring exchanges
735 per month
Time saved per exchange
8 minutes
Staff cost, including overheads
€42 per hour
Staff time freed each month
98 hours
Value of staff time per month
€4,116

735 × 8 ÷ 60 = 98 hours; 98 × €42 = €4,116

Illustrative assumptions. Compare the value of time recovered with subscription, setup, and ongoing administration costs.

Solutions

For teams that need recurring partner file exchanges to run cleanly.

Partner IntakeGive every exchange a clear starting point

Set expected files, periods, partners, and due dates so everyone knows what comes next.

Validation and SecurityCheck files before they reach your systems

Set clear file requirements, check incoming submissions, and keep every submitted file safely archived.

Tracking and AutomationKeep the full exchange visible

Track every submission from arrival to acceptance, then make the accepted file available and signal when it is ready.

How it works

Put a repeatable process behind every partner file.

01

Define Recurring File Exchanges

Set up each recurring exchange as a feed with its cadence, expected files, partners, and handoff path. The whole exchange is visible before anyone starts chasing the next attachment. Use Subfeeds when several partners share the same setup but need separate tracking.

  • Monthly, weekly, or deadline-driven file schedules
  • Required and optional files listed up front
  • Partner access, progress, and handoff visible in one place

Centralize Partner Submissions

Give each partner one controlled place to submit recurring files instead of chasing attachments, shared-folder links, and status updates across email threads. In a partitioned feed, partners see the files and history of their assigned Subfeed.

  • Partner-facing upload and download portal
  • Status for each recurring exchange, with separate tracking per Subfeed
  • Original file archive for every submission

More Partners, Less Setup

Run the same recurring exchange with more partners, without repeating the setup work. Subfeeds keep each partner's files and history separate, so your team always knows where things stand.

  • One setup for partners with the same requirements
  • Separate partner access, files, and history
  • Every partner's progress in one view

See who changed a feed, uploaded or downloaded a submission, and what happened next. Each action stays connected to the same accountable exchange instead of disappearing across disconnected messages.

  • See who was responsible for each action
  • Feed changes, submissions, downloads, handoffs, and validation activity in one place
  • Clear timing, responsible people, and outcomes for each recorded action
