Contract-to-invoice automation with pricing and proration
The strategy we mapped
We structured the work around three decisions that shaped the engagement. First, we settled the data model upfront: which objects needed integration, which fields would sync, and how to handle pricing complexity (list price, customer price, unburdened cost, and burdened cost across contracts, line items, and invoices). This clarity prevented rework downstream.
Second, we sequenced the work to prioritize the TD SYNNEX integration path (contracts and invoices flowing through to QuickBooks), since that was the critical path to the November billing cycle. Third, we built the integrations iteratively: authenticate systems first, confirm basic data flow, then uncover and fix edge cases (proration logic, exclusions, pricing field ambiguity) as the team ran test invoices.
Throughout the project we uncovered operational friction: the team's previous workarounds (manual invoice edits, unclear field names, missing margin calculations) and discovered constraints in HubSpot (bulk approval limits, native field immutability). We adapted the scope in phases: early work locked down pricing semantics and exclusion logic, midway work tackled the NinjaOne webhook setup in parallel, and later work addressed automation blockers (bulk invoice send, approval workflow scaling, QuickBooks sync reliability) as they surfaced in demos.
The solutions we executed
We integrated TD SYNNEX (the client's Microsoft CSP distributor system) with HubSpot to sync contracts and agreement line items. The integration pulls subscription data into HubSpot as standard line items and contract line items, applying exclusion rules to filter out unwanted SKUs (such as storage fees). The system handles proration logic: when a subscription is added or changed mid-month, the integration creates prorated line items dated to the following month so they land on the correct invoice without manual date editing.
Pricing fields were mapped to distinguish list price (MSRP), customer price (from the Stellar catalog with applied discounts), unburdened cost, and burdened cost (cost plus a contractual burden percentage). The integration also computes margin fields (invoice-level and total contract margin) to support commission and financial reporting, and exposes cost data so the team can validate external calculations. Once contracts are approved, the system auto-generates draft invoices populated with these fields, defaults payment terms to Net 30, and can be sent to customers and automatically synced to QuickBooks Online with correct billing entity mapping.
We set up NinjaOne webhook authentication and event-based integration to sync IT support tickets into HubSpot as a new Ticket object. The webhook triggers on ticket creation and update events, and a separate historical import backfills existing tickets. The integration associates tickets to companies so that support activity is visible alongside contracts and customer records for complete account context.
We also configured the native QuickBooks Online integration to sync invoices and accounting data bi-directionally between HubSpot and QuickBooks. This ensures that approved invoices reflect correctly in the accounting system and that customer payment data flows back. The team worked through customer-to-billing-entity mapping challenges (cases where the billing account in QuickBooks differs from the customer contact in HubSpot) to ensure sync reliability and prevent failed sends.
Custom code automation was built for three workflows: auto-sending approved agreement invoices to both the customer and QuickBooks; compiling master service agreement data on contract records; and tracking time entries. Custom actions within HubSpot workflows wire these automations to execute when conditions are met, removing manual handoff steps and reducing operational overhead.
What changed after the engagement.
The client's contract and invoice operations now run through an integrated pipeline connecting their Microsoft CSP distributor system to HubSpot and QuickBooks. Contracts sync automatically with correct pricing fields (list, customer, and cost), exclusion rules filter unwanted SKUs, and prorated line items land on the correct monthly invoice without manual date editing. Once approved, draft invoices populate with margin data for commission reporting, auto-send to customers, and sync to QuickBooks with correct billing entity mapping.
IT support tickets from NinjaOne also sync into HubSpot as a Ticket object and associate to companies for complete account context. Custom automations handle invoice distribution, master service agreement compilation, and time entry tracking, eliminating manual handoff steps and reducing operational overhead.
