Review Tips
Small details that prevent delays.
A polished application helps the review move faster. Before you submit, check these common issues.
Match names exactly
Your business name should match across tax, banking, insurance, and application details.
Use readable scans
Files should be clear, complete, and not cropped. Avoid blurry phone photos when possible.
Show payout details
Bank letters or voided checks must show the information needed to verify payout setup.
Check contact email
Use an email you actively monitor so review updates and follow-up requests are not missed.
Do I need all five documents before I start?
Yes. Having the full verification packet ready helps you complete the application faster and reduces the chance of follow-up requests.
What file formats should I use?
Use PDF or JPG files. Each file should be clear, readable, complete, and uploaded in the correct step.
What happens if something does not match?
CaptainGreek may request more information or a replacement document. The most common issue is a mismatch between legal business name, address, EIN, bank information, or insurance details.
How long does review take?
Review can take up to 3 business days. You will receive an email update after review or if additional information is needed.
When do I choose my selling plan?
Selling plan selection happens after approval. Once approved, compare the available plans and choose the setup that fits your business.
