HOW IT WORKS

Repeated values cost once: We count unique values for each selected check. Blanks and values we cannot recognize stay out of the bill. Your rows stay in the file.
Exact price up front: Choose the checks you need and see the total before you pay.
Unfinished checks refunded: If a paid run stops short, the unfinished share comes back to you.
Results available for 30 days: Return through the same link to download again, for 30 days from upload.
