Berlvis Credentials vs MailMergic

Berlvis Credentials is a web tool for generating batches of ID cards and certificates from recipient data and spreadsheet templates. Users can map Excel or CSV columns to template fields, then create CR80 card designs or A4 certificates. Outputs include 300 DPI PDF print sheets and PNG exports. QR codes can be linked to recipient records; paid plans add bulk QR signing, while independent verification is not generally available and the current beta centers on bulk issuance. The maker says template definitions are saved to the cloud, but uploaded photos and spreadsheets stay on the user's machine and are not persisted. For runs above a few thousand rows, its playbook advises splitting work into batches of 2,000–3,000 to keep browser memory predictable. The product is available in beta. The free plan provides Studio access with watermarked exports. ID Cards costs 5,000 NGN a month, and All Access costs 50,000 NGN a year; All Access adds certificates, bulk QR signing, brand kits, team templates, and priority support.

MailMergic turns spreadsheet data into personalized certificates, transcripts, diplomas, and other documents that can be downloaded or emailed. For education workflows, users can upload PDF or Word templates and bring in student records from Excel, CSV, or Google Sheets. The service produces a separate PDF for each student and says it can process thousands of rows in one run. Before generation, its AI checks merge data for missing values, formatting problems, and mismatches. Users can email documents to spreadsheet recipients and monitor delivery, opens, and bounces in a dashboard. Student information systems can provide CSV or Excel exports without an API connection; Pro and Enterprise also list Zapier and a public REST API. The online service says it encrypts data in transit and at rest, hosts it in the EU, and uses access controls. Its free plan allows 25 documents per month for one user, with watermarks. Pro is $39 a year, billed yearly; Enterprise is $66 a year, billed yearly. An offline app is $107 a year, billed annually, for macOS and Windows.
