Quote to order: what changes when most of your revenue starts as a quote instead of a checkout

Quote to orderQuote to order is the process where a buyer asks for a price, a person or a system prepares a quote, and the accepted quote becomes an order. In much of B2B it is the normal way to buy, not an exception. is the normal way a large part of B2B buys, and it looks nothing like a checkout. A buyer sends a list of items and quantities, often as a spreadsheet or a photograph of a parts list. Someone prices it, checks availability, adds freight, and sends back a document with a validity date on it. The buyer takes that document into their own approval process. Weeks later, a purchase order arrives referencing the quote number, and the quote becomes an order.

Five things happen in that sequence that a consumer checkout never has to handle. The price is not known when the buyer starts. A human is allowed to change it. The document expires. The buyer needs a reference number that survives into their purchase order. And the order arrives through a different door from the one the quote left by.

The reason this decides a platform choice is arithmetic. If 70 per cent of your revenue starts as a quote, then a platform that treats quoting as a bolt-on has bolted on 70 per cent of your business. If 5 per cent starts as a quote, a contact form and an inbox is a perfectly respectable answer and you should not pay for anything cleverer.

Shopify B2B has no buyer-initiated quote object, checked against Shopify’s own documentation on 20 August 2026. Shopify’s overview of B2B features lists companies and customers, payment terms, deposits, catalogues, volume pricing and quantity rules, vaulted cards, draft orders, partial payments, reorders and purchase order numbers. Quotes are not on that list.

What Shopify offers instead is the draft order. A merchant builds a draft order in the admin, assigns the B2B customer and company location, and Shopify then applies "the prices, payment terms, and checkout options" for that company automatically. The merchant sends it to the buyer as an invoice, and the buyer pays it. That is a merchant-authored quote delivered as a payable document, and for a lot of sellers it is genuinely enough.

What it is not is a request. The buyer cannot start it from the storefront, there is no counter-offer loop, and the draft order has no concept of a quote that expires unaccepted and then reports as lost business. If your sales managers ask "what is our quote win rate", the draft order will not tell them.

There is a related setting that is often mistaken for quoting and is worth separating out. A Shopify company location can be set to checkout to draft, which Shopify describes as meaning "all orders for the company location are submitted as drafts". That is merchant-side review before an order is accepted. It is not the buyer’s own organisation approving a purchase, and it is not a negotiation.

Three of the platforms Celeste scores carry quoting as a first-class object rather than as a repurposed order. All three were checked against vendor documentation on 20 August 2026.

BigCommerce B2B Edition treats sales quotes as a named feature, describing them as a way to "offer personalized deals with customized products and negotiated pricing", and its Buyer Portal lists "requesting sales quotes" as one of the workflows a company user handles for themselves. There is a Quote REST API in the B2B Edition API surface, which matters because it means a quote is an object your integration can read and write rather than a screen a person has to visit.

Shopware B2B Components ships a quote management module. Shopware documents the buyer starting it: partners "can initiate a quote request based on the contents of their cart". The merchant reviews the quote in the administration and "can also apply discounts to individual product items", and then "Partners are free to accept or decline the offer", after which "The system then automatically generates an order based on the accepted quote". That is a genuine loop, though Shopware’s own description stops at accept or decline rather than describing repeated counter-offers.

Drupal Commerce has no quote module in core. That is not a gap so much as a consequence of what it is: an open framework where a quote entity is something you model. It belongs on the shortlist when your quoting rules are specific enough that nobody’s product will fit them, and off it when you were hoping to configure rather than build.

Acumatica already has a sales quote document, and it is where your inside sales team quotes today. Acumatica’s own Shopify B2B connector datasheet, dated 23 September 2025, lists "Create Quotes from Shopify Draft Orders" and describes "importing Shopify draft orders as sales quotes". So the outbound leg exists as a shipped feature, not as a customization.

The hard part is the return leg, and it is the same hard part on every platform. A quote lives in the ERP because that is where availability, cost, margin approval and the customer’s credit position are. A buyer, once quoted, wants to accept online. That means the ERP has to push the priced quote back out to the storefront in a form the buyer can act on, hold the two copies in step while a rep edits lines, and then make sure that acceptance creates exactly one sales order rather than two.

Three specific things go wrong often enough to design for. The quote is edited in the ERP after it was published, and the storefront shows the old numbers. The buyer accepts, and a separate purchase order arrives by email for the same quote, producing a duplicate. The quote expires while it sits in the buyer’s approval queue, and nobody has decided whether an expired quote should still be acceptable at the old price. Write down your answer to the third one before you build anything, because it is a commercial decision, not a technical one.

None of this is exotic, and none of it is included in a platform licence. Budget the round trip as integration work with a defined owner, whether that owner is a native connectorA native connector is integration software published by the ERP or platform vendor themselves, configured rather than built. Acumatica ships native connectors for Shopify and BigCommerce. you have proven or middlewareMiddleware is a layer of software that sits between the ERP and the storefront, translating and enforcing rules that neither system holds on its own. It can be a hosted integration platform or a custom service. you are commissioning.

Teams underestimate this part and it is where quote-to-order projects actually stall. Moving quoting online is a change to how your sales team spends its day, and if you do not plan for that, the storefront gets ignored by the people whose numbers depend on it.

The list below is what we would put on a readiness checklist. If you cannot answer four of the six, the platform decision is not your first problem.
