Email attachments
Attachments are easy to send, but the accepted version, responsible person, due period, and correction thread quickly become hard to reconstruct.
Controlled supplier file intake

Replace the follow-up loop
Stop rebuilding supplier submission status from three different places.
Moving a file is only one part of supplier intake. Operations teams still need to know what was due, what arrived, what failed, and which attempt can move forward.
Ad hoc shared folders
A folder can hold files, but it does not explain what the supplier owes, whether the submission passed, or which replacement is current.
Manual tracking sheets
Separate spreadsheets and message reminders duplicate status by hand and drift away from the files and events they are meant to describe.
DTO Flow connects access, expectations, status, feedback, retained files, and handoff around the same supplier exchange.
Incoming supplier workflow
A visible path from supplier invitation to accepted submission.
The portal gives each recurring supplier exchange a defined owner, period, expected files, status, and retained history.
Define what should arrive
Create one incoming feed for the recurring supplier exchange, including its cadence, expected files, and acceptance behavior.
Give the supplier secure access
Invite the supplier contact and give them secure access to the exchange and actions intended for them.
Open the relevant period
The supplier opens the current or selected business period and sees which required and optional files belong to that exchange.
Submit with confidence
The supplier submits the expected files through a clear, secure path, with automation available when the exchange grows.
Keep every submitted version
Keep every submitted file connected to its supplier, exchange, period, and correction history.
Return status and correction feedback
Show processing or acceptance status. When agreed validation fails, return clear findings and let the supplier submit a corrected attempt.
Accept and move forward
The accepted file becomes current for the period and available for authorized download or API retrieval.
One exchange, two useful views
Make the next action obvious to the supplier and visible to your team.
The supplier gets a focused task list. The receiving team gets the operational context needed to manage the recurring process.
For invited suppliers
A simple place to finish the job
- Only feeds and actions assigned to the invited supplier
- Expected required and optional files for the relevant period
- Understandable status and clear validation feedback
- A clear path to correct and submit a new attempt
- Files published for download when outgoing access is granted
For operations teams
Control without inbox archaeology
- What is due, missing, late, or awaiting a supplier action
- Processing, correction, and acceptance status without chasing the sender
- The current accepted submission for each period
- Earlier attempts, replacements, and validation results kept together
- Attributed submission, notification, download, and status activity
A controlled two-way portal
Use the same accountable access model when files move back to partners.
When the same relationship also needs files from your team, an outgoing feed can make those files available through the assigned partner portal.
Publish for the period
Publish the approved file for the right period and make it available to the assigned partner in one clear place.
Notify the right partner
The right partner contacts receive a private notification when their file is ready.
Share with confidence
The assigned partner signs in and securely downloads the right file, while your team keeps a clear record of the exchange.
Original file archive
Know which file arrived, who sent it, and what replaced it.
Keep the complete story around every recurring exchange, with the current accepted file and every earlier correction easy to understand.
Every submitted attempt is retained
DTO Flow keeps each submitted file unchanged, while every later correction remains a distinct part of the exchange history.
Business context stays attached
Every file stays connected to the right supplier, exchange, period, and submission, so its business context remains easy to find.
A dependable file record
Clear file details help your team identify exactly what arrived and which submission is current.
Corrections keep their history
A later accepted submission becomes current for the period without deleting the attempts that came before it.
Optional spreadsheet validation
Turn supplier spreadsheets into dependable business inputs.
Keep complete supplier file packages together and add detailed spreadsheet checks wherever reliable data is essential to the next process.
- Apply validation where it creates the most value for your team
- Detailed checks cover the Excel and CSV tables your process relies on
- Agreed rules produce consistent, explainable acceptance decisions
- Suppliers receive clear locations, examples, and a practical correction action
Best fit
Built for recurring supplier exchanges with clear ownership.
The portal is strongest when a file exchange repeats, ownership is clear, and both organizations need one dependable record of what happened.
- The same supplier file is due every week, month, quarter, or business period
- A known supplier or partner is accountable for each incoming feed
- The receiving team can define the expected files, period, and acceptance path
- Some partners also need controlled access to files your team publishes for download
Common questions
What buyers ask before moving supplier files out of email.
How do suppliers get access?
Suppliers enter by invitation, sign in, and receive access to their assigned feeds. Every submission stays connected to an accountable recurring exchange.
How is each supplier's access kept separate?
Each partner user sees only the feeds and actions connected to their invitation, keeping every supplier relationship separate and private.
What happens when a supplier needs to correct a file?
The supplier sees clear feedback, corrects the file, and submits a new attempt. The earlier file and result stay attached to the period history.
Does every supplier file need spreadsheet validation?
Use detailed checks for the structured Excel and CSV data that matters, while keeping the supplier's complete file package together in the same controlled submission.
Can suppliers also receive files through the portal?
Yes. For an outgoing exchange, your team publishes the file, assigned partners are notified, and their authorized access stays connected to the exchange history.
A clearer supplier process
Give suppliers one reliable place to send what your team needs.
Start with one recurring supplier file, define what is expected, and replace the next email chase with a visible submission workflow.
