"Integrates with your CRM" can mean a logo on a page or a live two-way sync. This guide explains which fields should flow from the deal into the proposal, what should be written back, and how to compare tools on that basis.
CRM integration in proposal software means that the proposal tool and the CRM share the same deal record, so the seller never types a company name, contact or deal value twice, and the CRM always shows the current state of the proposal. That definition has two directions. Inbound: deal data flows into the proposal. Outbound: proposal events flow back to the deal. Many tools only do the first half, and some do neither beyond a link in a sidebar. When a vendor says "integrates with HubSpot", the useful follow-up question is "which fields, in which direction, and how often". This article uses Proposal Expert, an AI proposal and quote tool, as the example, and lists criteria you can apply to any product.
Five fields cover nearly every proposal: the deal name, the contact (name and email), the company, the pipeline stage and the deal amount. With those five in place, a seller can open a deal in the CRM and create a proposal in two clicks: choose a template, confirm the prefilled client details. Proposal Expert does this with HubSpot, Salesforce and Monday today, as a live two-way connection. The deal, contact, company, stage and amount arrive in the proposal, the client block and the pricing total are prefilled, and a later change to the contact in the CRM is reflected in the proposal until it is sent. Two details are worth checking with any vendor. Does the sync pull the contact from the deal association, or from a separate search the seller has to run? And does it treat the CRM as the source of truth for the company record, so the proposal does not create duplicates?
The outbound direction is where the value for sales management lives. At minimum, the proposal status (draft, sent, viewed, signed, declined) and the proposal value should be written back to the deal, so the pipeline report in the CRM is correct without anyone updating it by hand. Proposal Expert writes the proposal status and value back to the linked deal in HubSpot, Salesforce and Monday. Writeback of the value is opt-in per workspace, because some teams keep the CRM amount as a forecast and do not want it overwritten by a proposal total that includes optional items. Ask the same question of any tool: can you choose which fields are written back, and can you turn writeback off for a pipeline?
The honest status as of September 2026. 1. HubSpot: live, two-way, deal-to-proposal in two clicks, status and value written back. 2. Salesforce: live, two-way, same field set, connected through an OAuth app with PKCE. 3. Monday: live, two-way, same field set. 4. Pipedrive: the adapter is built and tested, activation is pending marketplace approval of the OAuth app, so it is not yet available to customers. 5. Zoho CRM, Microsoft Dynamics 365, Teamleader and Exact Online: coming, not yet available. If your CRM is in the last group, the practical alternative today is a webhook from the CRM or a manual import of client details, and you should plan on that rather than on a promised date. The integrations page shows the current list.
PandaDoc, Proposify and GetAccept all list HubSpot and Salesforce integrations, and so does Proposal Expert. The logo tells you very little. Use these six criteria and fill them in from the documentation of each vendor or from a trial, not from the sales deck. 1. Direction: inbound only, or two-way with writeback? 2. Fields: which of deal, contact, company, stage and amount are synced, and can you map custom fields? 3. Trigger: is the proposal created from inside the CRM, or does the seller start in the proposal tool and search for the deal? 4. Timing: real-time through webhooks, or a scheduled poll every few hours? 5. Plan gating: is the integration available on the plan you would actually buy? Several vendors reserve Salesforce for enterprise tiers, so check the plan page and not the integrations page. 6. Failure handling: what happens when a token expires or a field is missing? Do you get a notification, or does the sync stop silently? The comparison page on this site covers feature-by-feature detail, but these six questions decide whether an integration survives the first month.
Take a consulting firm with a five-stage pipeline in HubSpot as the example. 1. A deal reaches the "Proposal" stage. The seller opens the deal and clicks "Create proposal". Template chosen, client details prefilled: two clicks. 2. The AI draft fills the sections from the deal notes. The seller edits the scope and builds the pricing table from the product catalog. 3. The proposal is sent. The HubSpot deal shows the status "Sent" and the proposal value, without manual entry. 4. The client opens the proposal. Real-time tracking shows which sections were read, and the engagement score from 0 to 100 updates in Proposal Expert. A score above 70 within the first day is a good moment to call. 5. The client signs electronically. The deal shows "Signed", and the value on the deal matches the signed total. The measurable gain is not the two clicks. It is that the pipeline report is right at the start of the week without an hour of data entry.
It should not. A well-built integration reads the contact from the deal association and never creates a record without an explicit action. Proposal Expert reads deal, contact and company from the CRM and writes only status and value to the deal.
Check whether the tool allows one connection per workspace or several. Connecting two CRMs to one workspace creates two sources of truth for the same deal, so one CRM per workspace is the practical setup for nearly every team.
The Pipedrive adapter is built and tested. Activation depends on marketplace approval of the OAuth app, and there is no committed date. The integrations page shows the live status, and existing HubSpot, Salesforce and Monday connections are unaffected.
