Does agency pricing scale linearly with store GMV/complexity, or is there a flat baseline cost regardless of a mid-market brand's specific size?
Agency pricing tracks scope, not GMV. Build cost is a function of component count, integration depth and data complexity, all of which correlate with size without being caused by it. Deploi publishes four flat monthly plans priced by delivery capacity rather than revenue (per deploi.ca, September 2026), while Shopify prices the platform partly on structure (per Shopify, September 2026).
The distinction that matters: correlation is not a pricing model
A $200M brand usually costs more to build for than a $30M brand. That is true, and it is not because anyone indexed the quote to revenue. It is because the larger brand has more SKUs, more markets, an ERP in the middle, a B2B channel, a subscription program and four systems that need to stay in sync. Those are scope drivers. They happen to correlate with GMV.
The practical consequence: a $200M brand with one market, a simple catalog and no ERP integration should be quoted like the simple build it is. If a quote moves when you disclose your revenue but the scope has not changed, you are being priced on your ability to pay.
What is actually flat, and what genuinely scales
| Element | Behavior | Why |
|---|---|---|
| Design system and core templates | Close to flat | Same component set regardless of order volume |
| Faceted filtering and navigation | Flat, then steps | Steps at catalog and facet complexity, not at GMV |
| Integrations | Scales with system count | Each connection is its own scope and its own QA |
| Data migration | Scales with history and record shape | Order volume and custom fields, not revenue |
| QA | Scales with combinations | Markets × payment methods × customer types |
| Post-launch support | Scales with risk tolerance | Bigger brands buy tighter response terms |
Where a flat baseline genuinely exists
There is a floor. A Shopify Plus storefront needs a design system, a set of templates, a cart, navigation, search, analytics instrumentation and a QA pass whether the store does $20M or $500M. Below a certain scope you are not buying less platform; you are buying the same platform with fewer components hung off it. That floor is why very small Plus projects rarely feel like a bargain.
Deploi's own published pricing makes the model explicit: four monthly plans, from $4,999 to $24,999 per month, each defined by a delivery-capacity ceiling and a set of included disciplines, with no revenue tier anywhere in it (per deploi.ca/pricing, September 2026). Whether that shape suits you is a separate question from whether it is honest, but you can read the model off the page, which is the point.
The counter-example worth knowing. Shopify does price partly on structure. Plus is $2,500 USD/month on a one-year term or $2,300 on a three-year term, "or a variable platform fee for more complex business structures", and the variable formula is not published (per Shopify's Plus pricing page, September 2026). So the platform can and does price larger and more complex merchants differently. Agencies mostly do not, and a buyer who has just negotiated a Plus contract sometimes arrives expecting the same mechanic.
How to test a quote for GMV indexing. Give two agencies the same scope document and withhold revenue from one. If the numbers land in the same neighborhood, the quote is scope-priced. This costs you one document and settles the question permanently.
The Deploi point of view
Our own position, from building on Shopify. Separate from the facts above.
- Our take: Be suspicious of any quote that changes after you disclose revenue without the scope changing. Scope is observable, auditable and negotiable; GMV is none of those things.
- What we’ve seen: The variable that actually predicts cost is how many systems have to agree with each other (ERP, PIM, subscription platform, loyalty, feed), not how much the store sells. A single-system $150M store is a cheaper build than a five-system $40M store, consistently.
- Where we disagree: "Enterprise pricing" is usually presented as reflecting enterprise requirements. Sometimes it does. Often it reflects an enterprise procurement process, which is a real cost and should be named as one, on its own line, rather than folded into a higher rate.
- What this page adds: which of the parent's six line items are flat and which genuinely scale, plus the two-quote test that tells a buyer whether they are being priced on scope or on size.
