CPA Media Buying for Ecommerce and Food Delivery in Mexico

In Mexico a cash voucher registers as a conversion the moment it is generated, and between 35 and 50 percent of those vouchers are never paid at the counter. If your CPA postback fires on generation, you are paying partners for cash that never arrived. Moving the event to settlement is the first thing we change, and on a typical food delivery or DTC account it removes 20 to 30 percent of the payable conversion count in week one. The postback is the whole job: Before we buy anything we rebuild the server-to-server conversion flow: one event per payable outcome, fired from your backend after settlement, carrying order value, payment method and a stable order ID. Conekta, Mercado Pago and dLocal webhooks are the trigger, not the client-side pixel. Cash on delivery gets its own event fired on courier confirmation. Where mobile is in scope we wire the same logic through AppsFlyer or Adjust against a validated purchase event rather than a registration. An advertiser unwilling to change the postback should not hire us to buy CPA, because everything downstream is measured on it. Where we buy: Direct partner deals first — cashback and comparison properties with real Mexican traffic, WhatsApp community operators, food and drink creators on a hybrid of flat fee and CPA. Networks second, and only ones that disclose sub-source at ID level: Admitad LatAm, Rakuten Advertising's regional desks, and self-hosted programs where we can see the raw log. We do not buy blind from a network reporting rolled-up sub-IDs. Fraud, and what we actually check: Click-to-conversion time distributions, IP-to-payment-geography mismatch, and the ratio of new-device to returning-device conversions per sub-ID, run weekly in 24metrics or Anura against rules tuned to the account rather than the vendor default. The check that catches the most here is simpler: voucher-generated to voucher-paid rate, by sub-source. Real traffic pays vouchers at 55 to 70 percent. A sub-source at 95 percent is stuffing cookies onto buyers who already paid, one at 8 percent is buying bot form fills, and both come off in the same week. What we will not buy: Incentivised traffic on a food or retail account, in any packaging. Search on your own trademarks — written into every insertion order as immediate termination, not a warning. Pop, toolbar and browser extension inventory. Any placement we cannot open on a live URL and look at ourselves. And we do not accept a CPA target handed down without the contribution margin behind it; if you cannot say what an order is worth net of discount and delivery, we cannot say what to pay for one. Not for you if: You need spend committed inside a week. Our launches run four to six weeks of tracking work before meaningful volume, and we will lose the engagement rather than buy against a postback we do not trust. Also not for advertisers whose unit economics only work below roughly eight dollars per acquisition — that is buying on price, and there are shops that will do it cheaper than we will. How the money moves: Our fee is flat and invoiced separately from media. Partner payouts run through your own platform account, so you hold the funds and the ledger throughout and can end the engagement without a migration. We hold the terms, the sub-source rules and the weekly evidence behind every cut we make.
