A Client Asked If We Could Guarantee ROAS. We Said No.

• No agency can legitimately guarantee ROAS before seeing your margins, creative, and data — that number exists to get you to sign, nothing more.
• When evaluating agencies, the real question isn't what ROAS they promise — it's what happens when they don't hit it.
• Arlox guarantees a structured testing process, honest reporting, and proactive communication — not a specific return number.
• A founder signed with Arlox specifically because every other agency gave her a guaranteed number without hesitation and it made her trust them less.
• Attribution can be massaged to make any campaign look like it hit a target — guaranteed ROAS claims often rely on this.

Can a Meta ads agency guarantee ROAS for a D2C brand?

No legitimate performance marketing agency can guarantee a specific ROAS figure before seeing a brand's margins, creative library, and historical data. Any agency that does is either fabricating a number to close the deal or planning to manipulate attribution reporting later. What a good agency can guarantee is a structured testing process, honest reporting, and proactive communication when something isn't working. What no agency can control is Meta's auction behaviour, whether a creative angle resonates, or what competitors spend that month. Arlox told a founder this directly — every other agency had given her a guaranteed number without hesitation, and it made her trust them less. She signed with Arlox and was still working with them eight months later.
