RetailerBoost vs Bidnamic AdSpend
Both of us fund your Google Shopping ads and bill a share of the sales. What differs is what counts as a sale we generated, how long it takes to switch on, and how much of your revenue you hand over.
The four differences that matter
Everything else on this page is detail. These are the four things that change what you actually pay and when you actually start.
We bill only when the order lands within a day of our click. Bidnamic bills on a 30-day last-click window, so a shopper who clicks once and buys three weeks later still costs you a share.
Install our app, set your rate and cap, connect Merchant Center. Bidnamic AdSpend is configured by their team after an email exchange and a collaborator invite.
You install ours yourself from the Shopify App Store. Theirs is, in their words, "a private, invitation-only app for selected stores" ahead of a future App Store release.
One rate, published, changeable in the dashboard. Bidnamic recommends a share from a margin calculator, limited to a 15% to 30% band, changeable once a month by email.
A 30-day window is a very comfortable place to send an invoice from
Bidnamic's own FAQ puts it plainly: "Attribution works on a last click, 30-day window: Bidnamic must be the last paid click before the order, within 30 days."
Thirty days is the default across paid search and affiliate, so nobody can call it unusual. It is also the single most generous setting available to the party doing the billing. A shopper clicks a Shopping ad on the 1st, browses, leaves, remembers your brand three weeks later, comes back directly and buys on the 27th. That is an order you were very likely getting anyway. On a 30-day window it is a commissionable order.
Our window is 24 hours. The click and the purchase have to belong to the same shopping trip. It is a deliberately hard test, and it costs us real money: every order that a 30-day window would bill you for and ours does not is revenue we walk away from. What you get in exchange is a bill that moves with the sales the advertising actually caused.
It compounds with the rate
This is the part that gets missed. A 30-day window does not just change which orders get billed, it increases how many orders get billed on exactly the same traffic. So the gap between our 12% and their 15% to 30% is not simply three to eighteen points of revenue. It is that wider spread, applied to a bigger pile of attributed orders.
Five minutes, or one to two weeks
Both routes need access to Google Merchant Center, so that part is even. Everything before it is not.

Nobody here is new to this
Funded Google Shopping is a young category, and every vendor in it will tell you about their track record. Here is ours.
We did not arrive at funded ad spend from the outside
Our founding team spent a decade building Europe’s largest Google Comparison Shopping Service, running Google Shopping on a pure cost-per-sale basis at a scale very few operators have worked at. Performance-funded Shopping is not a new product line for us. It is the only thing we have ever done.
Risking our own capital is the old job, not the new one
A CSS on cost-per-sale carries the ad spend and gets paid only when a sale lands. That is the same balance sheet risk RetailerBoost takes on every campaign, run across 35,000+ retailers before RetailerBoost existed. Nobody on this page is learning that model live.
The platform is the product
A Y Combinator alumnus and an exited ecommerce founder built the platform: automated bidding, a public Shopify app, three billing rails and a self-serve signup that takes five minutes. That is why you can be set up in an afternoon rather than over one to two weeks.
What the rate costs you
The same $100,000 of attributed Google Shopping revenue, at each rate on the table.
And remember the attributed revenue figure itself is not fixed. On a 30-day window, more orders qualify as attributed than on a 24-hour one, so the same traffic produces a bigger number to apply the rate to.
These numbers are an illustration of commission arithmetic on a round figure, not a forecast of what either service will generate for your store. Actual revenue, attributed order volume and the right commission rate depend on your margins, catalog, category competition and return rate. Model your own numbers with our commission calculator before making a decision.
Bidnamic is the more traditional choice
It is an agency relationship with the funding attached. That suits some retailers, and if the following all sound like you, it may suit yours.
- You want a named account team to meet with, and you are happy for that overhead to come out of the revenue share.
- A one to two week onboarding, run over email, is not a problem for you.
- You are on Shopify, you expect to stay on Shopify, and one billing route is all you need.
- A 30-day attribution window at a 15% to 30% share reads as reasonable to you once you have modeled it.
Pick RetailerBoost if
- You only want to pay for orders that happened within a day of the click, not within a month of it.
- You want to be set up this afternoon, without a demo call or an eligibility queue.
- A published, fixed 12% beats a negotiated 15% to 30%.
- You would rather install a public app than hand over a collaborator seat with theme code access and your product cost prices.
- You are not on Shopify, or you want to choose your billing rail: Shopify usage billing, Stripe, or commission through your existing affiliate network.
- You want the operators who built Europe's largest Google Shopping CSS running your campaigns.
