What to change
Ask your supplier to distinguish file-selection and transfer states accurately, with a clear way to recover if the receiving service does not accept the attachment.
A worked example
Illustrative example
A selected document shows Uploading until transfer completes, then Ready. A failure leaves a clear retry or remove route instead of an ambiguous filename.


Why this matters to your practice
A filename appearing on screen does not necessarily mean its contents have reached the website. Visitors need to distinguish chosen, uploading, ready and failed. Ask your supplier to demonstrate those stages on a slower test connection. Agree when the person may continue and what happens if transfer fails. Your team should judge whether the wording describes the real outcome, rather than relying on a progress bar that looks finished before the receiving system has accepted the file.
A practical review example
A file name may appear immediately even though its contents are still transferring. Ask your supplier to use a larger harmless test file on a slower connection and demonstrate the changing state. Then simulate failure and review the offered retry or removal. The final Ready message should correspond to the agreed acceptance signal, not merely a progress bar reaching its end. A visitor needs to know whether continuing will include the intended attachment, while spoken feedback should communicate meaningful changes without announcing every tiny movement.
How to check the result
Accept when visitors can tell whether an attachment is actually ready and submission behaviour matches that state.
A mistake to avoid
A progress bar reaching its end may describe bytes sent without confirming the server accepted the file, so define the completion signal carefully.
