addy will provide you with a package of documents and materials that you can hand to your lawyer for entering into the minute book to officialize the transactions.
Closing an issuance will allow you to countersign and therefore accept the subscription agreements, meaning you will therefore have an obligation to issue the securities under this offering.
You'll see a summary of the accredited and crowdfunded subscriptions prior to reviewing and countersigning the package of documents. 
The first documents that you will be provided with are software generated directors consent resolutions, which, among other things, once signed, issue the securities for which subscriptions were accepted.
You will find the DCR to issue the units or shares in the addy Data Room (Data Room > Legal > Directors' Consent Resolutions And Shareholders' Consent Resolutions). This is also where you will find the CSR (Data Room > Legal > Corporate Registry Forms):
Once the securities for which subscriptions were accepted have been issued, the platform will generate electronic security certificates to each applicable subscriber and the securities ledger will be updated to reflect the issuance.
To find your Subscription Agreements, head to the addy Data Room's Real Estate tab (Data Room > Real Estate > Legal):
Your signature as an authorized signatory will be electronically placed on each selected subscription agreement, thereby accepting the subscription to the securities subscribed to therein.
Your subscribers will be notified of the acceptance of the subscription.
