Help & frequently asked questions

Subscribe to AtlanticM&A Cloud Migration on the AWS Marketplace listing. AWS handles billing for the Cloud Migration product — your AWS bill will show the line item.

After subscribing, AWS redirects you to a registration page on atlanticma.ai. Sign in with your existing AtlanticM&A account (and we'll attach the subscription), or create a new account (and we'll provision a free Independent workspace alongside the Cloud Migration tools).

Every AWS Marketplace customer gets a free AtlanticM&A Independent workspace alongside their Cloud Migration subscription: 1 user, 1 project on the M&A integration side. There's no separate fee for it; it's included so you have somewhere to run the engagement from.

Need more capacity? Move to the Independent, Firm or Enterprise plan for your M&A integration work. Independent and Firm are billed separately from your AWS subscription; Enterprise can be bought through AWS Marketplace or by invoice.

Registration tokens are valid for approximately 1 hour after AWS issues them. If yours has expired, the page will say so — to recover:

1. Return to the AWS Marketplace AtlanticM&A listing.
2. Click 'Set up your account' — AWS will issue a fresh token and redirect you back.
3. If it still fails, email support@atlanticma.ai with your AWS account ID. We can link the subscription manually.

Yes. After subscribing on AWS, the registration page detects you're signed in and offers a one-click 'Link AWS subscription to your tenant' button. The link is one-time and idempotent — clicking again does nothing.

If you have multiple AtlanticM&A tenants, sign in to the one you want to attach the subscription to first, then complete the registration flow.

Cancel through AWS Marketplace — go to your AWS Marketplace subscriptions page and cancel there. AWS notifies us, and we revoke the Cloud Migration tools immediately.

Your AtlanticM&A workspace remains — only the Cloud Migration features (MRA, TCO, funding bundler) lock when the AWS subscription ends. The free Independent baseline you received at sign-up remains active indefinitely.

Most likely the registration step was never completed. Two options:

1. Re-run the registration flow from the AWS Marketplace listing (your AWS subscription stays active; this simply re-attaches it).
2. Or email support@atlanticma.ai with your AWS account ID and the email address on your AtlanticM&A tenant. We can link them manually.

For Enterprise, yes: Enterprise plans for M&A integration can be bought through AWS Marketplace or by invoice, so talk to us. Independent and Firm plans are billed from inside the app, separately from your AWS subscription. Both run side by side: you can have an AWS Cloud Migration subscription and a Firm plan on the same tenant.
