Contract automation grows up: admin permission maps, 2FA, and forms that do their own arithmetic.
Contractbook released a batch of six changes on a single day covering three areas at once. Administration gets a company-wide Spaces access page answering who can reach which space and with what permission, plus OTP two-factor authentication at login. Contract creation gets calculation fields in forms that compute totals and pro-rated amounts and insert them into the document automatically. The AI side gets a new extraction model and a dedicated place to manage AI upload contract types, with built-in defaults now editable per company.
Double is turning its accounting assistant into the way the work gets done
Double ships weekly, and nearly every release extends Ask Double rather than the surrounding application. In the last two months it has learned to build workpapers by reconciling accounts against supporting documents, import accruals, create and manage client metrics through the MCP and API, take voice input, and — in private beta — reach into Slack, Notion, and HubSpot. The non-assistant work fills in what firms need to trust that: role-based restrictions on editing client properties, and check transactions in AI Transactions.
Contractbook released a batch of six changes on a single day covering three areas at once.

The AI side gets a new extraction model and a dedicated place to manage AI upload contract types, with built-in defaults now editable per company.
The pattern is a product being fitted for larger customers: the access-visibility page is gated to Accelerate and Enterprise plans, group-level company permissions landed earlier in the year, and 2FA closes the obvious procurement objection. Meanwhile the AI features are moving from fixed behaviour toward configurable behaviour — extraction types are now a company's own list rather than the vendor's. Calculations remove the last common reason to edit a generated .docx by hand.
The admin thread points toward more permission surface — audit trails or per-space delegation would follow naturally from a page that already explains where each permission comes from. Nothing in these entries indicates how much extraction accuracy actually improved.

The non-assistant work fills in what firms need to trust that: role-based restrictions on editing client properties, and check transactions in AI Transactions.
The assistant is moving from answering questions to performing the billable work — tie-out, accrual setup, metric standardization across a whole book of clients. Each release pairs that with an access or permissions control, which is the pattern of a vendor that knows the objection is liability rather than capability. The accounting engine itself keeps advancing underneath, most recently with prepaid contracts paid in installments.
Given the review-and-signoff question these features raise, the likely next step is an approval or audit trail around what Ask Double produces rather than another task it can perform.
