Money and decisions6 minOwn delivery app or iFood: when to build yours
An own delivery app pays off when you already have repeat customers and marketplace commission is eating your margin: on iFood it runs 12% to 23% per order, plus 3.2% when payment goes through the app. If you still need to be discovered, the marketplace is still your storefront. The most common path is to use both: iFood brings new customers and your own app keeps the ones who order again.

A software development contract needs to state what will be delivered, by what date, at what price, and how acceptance is measured. It also needs to make clear that the code, files, and accounts are yours, how scope changes work, the warranty after delivery, the data protection rules, and how to exit the contract with everything in hand.

A website's monthly maintenance cost depends on three things: the platform it was built on, how many plugins and integrations it uses, and what needs updating during the year. Add the fixed bills, like hosting and domain, to the hours of work to update, back up, and fix. Ask for that amount in writing, with what's included and what's not.
