How Does DoPricer CPQ Work with HubSpot?

Overview

DoPricer CPQ is a HubSpot Marketplace App that sits alongside your HubSpot portal and automatically applies the correct price and discount to every new line item created in your Deals and Quotes. It does this in the background, without any action required from your sales reps — they add a product, save, wait a few seconds, press browser refresh, and the correct price is already there.

This article explains exactly how that integration works: how DoPricer connects to HubSpot, what it listens for, what it does when it detects a new line item, and what it leaves behind in your HubSpot data.

How DoPricer connects to HubSpot

DoPricer integrates with HubSpot using two standard HubSpot mechanisms: webhooks and the HubSpot API.

Webhooks

A webhook is an automatic notification that HubSpot sends to DoPricer whenever something happens in your portal. DoPricer listens for two webhook event types:

1. New line item created — the primary trigger. Fires whenever any new line item is created anywhere in your portal.

2. Line item price property updated — used exclusively by the Price Lock feature (see below).

HubSpot sends these webhooks to DoPricer's API endpoint automatically. There is no polling or scheduled checking — DoPricer reacts in real time as events occur.

HubSpot API

Once DoPricer receives a webhook, it uses the HubSpot API to fetch additional data it needs — the parent Deal or Quote, the associated Company, and the product from your product library. It then uses the API again to write the updated price and discount back to the line item.

Each new line item typically requires approximately 14 API calls to process fully. HubSpot enforces a rate limit of approximately 110 API calls per 10 seconds per portal, which means DoPricer can process approximately 7– 8 line items per second. On deals with many line items, there may be a brief delay before all prices are updated.

What DoPricer installs in your HubSpot portal

When DoPricer is installed, it creates a set of custom properties in your HubSpot portal. These properties are the mechanism through which DoPricer reads your pricing rules and records its decisions.

All properties are created in a HubSpot property group called "DoPricer", except for custom price list properties on the Product object, which are created in a group called "Price".

Properties created on the Company object

These are set by you (or your HubDo Support contact) to configure pricing rules for each buyer Company.

Property	Internal name	Type	Purpose
DoPricer Enabled	dopricer_enabled	Dropdown	On/Off switch for DoPricer at Company level. If Off or empty, DoPricer takes no pricing action for this Company.
Discount By Product Items	dopricer_discount_items	Text	Per-SKU discount rules. Format: `SKU=discount%` pairs separated by commas, e.g. `ABC123=10,ABC124=20`. Highest‑priority discount source.
Discount Default	dopricer_discount_default	Number	Fallback discount % applied when no SKU or category match is found.
DoPricer Pricelist	dopricer_pricelist	Dropdown (single-select)	Specifies which price list applies to this Company. One price list per Company at a time (see Multi-currency support below). Created by HubDo Support on request.
Product category discount properties	dopricer_discount_cat_[category]	Number (one per category)	One property per product category — holds the discount % this Company receives for products in that category. Created by HubDo Support when category discounts are configured.

Properties created on the Product object (product library)

These are set on individual products in your HubSpot product library.

Property (Label)	Internal name	Type	Purpose
DoPricer Discount Always Empty	dopricer_discount_never	Dropdown	If set to Yes on a product, no discount will ever be applied to line items for that product, regardless of Company-level discount settings. Commonly used for delivery charges, fees, etc.
DoPricer Discount Message	dopricer_discount_message	Text	When populated on a product in the library, DoPricer skips all pricing and discount evaluation for any line item created from that product.
Product Category	dopricer_product_category	Dropdown	Classifies the product into a category for category-based discounting. Created by HubDo Support when category discounts are configured.
Custom price list properties	custom_price_[name]_[currency]	Number (one per price list)	Holds the custom price for this product in a given price list and currency, e.g. `custom_price_wholesale_usd`. Created in the “Price” property group.

Properties created on the Line Item object

DoPricer writes to these properties on every line item it processes, recording exactly what it did and why.

Property (Label)	Internal name	Purpose
DoPricer Discount Message	dopricer_discount_message	Records the discount decision. If this property already contains a value when DoPricer checks a line item, DoPricer treats it as already processed and skips it, preventing duplicate processing.
DoPricer Price Message	dopricer_price_message	Records the price decision, including whether a custom price list or standard price was used.

What happens when a new line item is created

When DoPricer receives a webhook for a new line item, it follows this sequence:

Step 1 — Identify the parent object

DoPricer fetches the line item and determines what object it is associated with: a Deal, a Quote, or something else (an Order, Invoice, Subscription, or Custom Object).The line item is counted toward your subscription usage at this step, regardless of what DoPricer finds.

DoPricer receives a webhook for every new line item created in your portal — HubSpot does not filter by object type before sending. If the line item is not on a Deal or Quote, DoPricer records this and stops. No pricing or discount evaluation occurs.

Step 2 — Fetch the Deal or Quote

DoPricer fetches the Deal (or Quote) record to get two pieces of information:

The deal currency — critical for applying the correct price
The associated buyer Company

Step 3 — Check the Company

DoPricer fetches the Company record and checks the DoPricer Enabled property. If this is set to Off, or is empty, DoPricer writes "Company Off " to the line item's DoPricer Discount Message property and stops. The line item is still counted toward subscription usage.

Step 4 — Determine the price to apply

DoPricer checks whether a custom price list applies to this Company:

The Company record holds a DoPricer Pricelist property (a single-select dropdown). If a price list is set — for example, "Wholesale USD" — DoPricer fetches the product from your product library using the line item's SKU and reads the corresponding custom price property on that product (e.g. the "custom_price wholesale_usd" value).
If that property is populated, DoPricer replaces the line item's selling price with that value.
If the property is not populated for that product, the price is left unchanged.
Currency matching: DoPricer always checks that the custom price currency matches the Deal or Quote currency. If they don't match, DoPricer falls back to the standard HubSpot price for that currency and records this in the DoPricer Price Message property.

Step 5 — Determine the discount to apply

DoPricer checks for applicable discounts in strict priority order, stopping at the first match:

Priority	Discount type	Where it is set	How it works
1st	Per-product (SKU-based)	Discount By Product Items on the Company	DoPricer checks whether the line item’s SKU appears in the list. If found, that discount is applied.
2nd	Per-category	Product Category on the product + matching category discount property on the Company	DoPricer checks the product’s category, then looks for a matching discount property on the Company.
3rd	Default discount	Discount Default on the Company	Applied when no SKU or category match is found.
None	No discount	-	If all three are empty, no discount is applied.

Override — Discount Always Empty:

If the DoPricer Discount Always Empty property is set to Yes on the product in the product library, no discount is ever applied to line items for that product — regardless of Company-level settings.

Step 6 — Update the line item and record the outcome

DoPricer updates the line item with the determined price and/or discount. It then writes to two properties on the line item:

DoPricer Discount Message — records the discount decision. Exact values written by DoPricer:

Value	Meaning
Discount Always Empty	Product is marked as never discountable
Line Item Discount	A per-product SKU discount was applied
Category Discount	A product category discount was applied
Default Discount	The Company default discount was applied.
No Discount	No discount rule matched; none applied
Company Off	DoPricer is disabled for this Company

DoPricer Price Message — records the price decision. Example values:

Custom price 2257 applied from custom_price_wholesale_usd — a custom price list was applied

Standard price 2700 applied based on deal currency EUR — the deal currency didn't match the price list, so DoPricer fell back to the standard HubSpot price.

Once the DoPricer Discount Message property contains any value, DoPricer treats that line item as already processed and will not re-evaluate it — this prevents duplicate processing if the line item is detected again.

Step 7 — Count the line item

The line item is added to your portal's monthly tally, which determines your subscription charges for that month.

The browser refresh requirement

DoPricer updates HubSpot data in the background. The HubSpot UI does not automatically reflect those changes until the page is refreshed. Sales reps must press browser refresh to see DoPricer's applied prices.

Which HubSpot objects DoPricer supports

DoPricer processes line items associated with:

HubSpot Deals — always supported

HubSpot Quotes — supported, and can be toggled on or off per portal

DoPricer does not process line items on Orders, Invoices, Subscriptions, or Custom Objects. Even though it receives webhooks for line items created on those objects, it detects the association and takes no pricing action. Those line items are still counted toward subscription usage.

Whether DoPricer acts on Quotes is a per-portal setting, separate from the Company-level DoPricer Enabled toggle. Contact support@hubdo.com to change this.

Price Lock

Price Lock is a feature that monitors existing line items and re-applies DoPricer's price if it detects the price has been manually changed. It is triggered by the "line item price property updated" webhook — not the new line item webhook — so Price Lock activity does not count toward your subscription usage.

Object	Price Lock default
Quotes	On by default
Deals	Off by default

Price Lock is on by default for Quotes because HubSpot's Quote Builder auto-saves line item changes back to HubSpot every few seconds, without re-fetching the underlying data. Without Price Lock, a sales rep working in Quote Builder could accidentally overwrite DoPricer's correct prices. Price Lock silently restores them.

Price Lock settings are managed by HubDo. To change them, contact support@hubdo.com.

Multi-currency support

DoPricer is currency-aware throughout. Each custom price list property name ends in a 3-letter ISO currency code (e.g. "custom_price_wholesale_usd", "custom_price_wholesale_gbp" ), and DoPricer always matches the price list currency to the Deal or Quote currency before applying a price.

Each Company can have one active price list at a time. This is by design — if multiple price lists were set on the same Company simultaneously, DoPricer would have no reliable way to determine which one to apply.

If a customer buys in multiple currencies and needs different price lists for each, the solution is to create separate Company records in HubSpot — one per buying currency or entity. See How does DoPricer CPQ handle different currencies? for full guidance.
