There are various upgrades you can purchase to make obtaining pokemon more fun and efficient.

Gives your party 1 exp for every interaction you make (more with Niet bonus!). Very useful, and you should get it as soon as you feel like you can save the GP for it, as it is a bit expensive for early on.

It's kind of obvious that you want to increase how many shelter adoptions you can do. Even just getting the Shelter Pass B will more than double how many adoptions you can make daily. This should be one of your first GP-based purchases.

Buy the scour slot and scour boost upgrades as soon as you can! This should be your second GP purchase after a bigger shelter pass. Seriously, this is the main way you'll get GP, summon items, early mega-stones, and totem pokemon, not to mention various sellable items for Credits. Set aside a group of pokemon, identify their preferred scour area, and switch them out when they hit 60% energy (higher energy = better items). Your pokemon can find anything from berries to evolution items, but the most important items are boxes. Boxes can contain GP, evolution items, form changing items, or summon items.

This will help a lot in getting the eggs you need for filling out the egg-dex. You'll want to check egg-groups for your pokemon, because you can breed different species as long as their egg-groups match. Spyglass - You want to get this as soon as possible. This lets you identify which eggs are which when breeding two different species. Matchup checker - Useful for knowing how likely it is you'll get an egg from a pair, and how many interactions you'll need to do. Pretty important. Exp booster - Upgrade as you feel like it. Useful for leveling up pairs to maximum efficiency, but not critical. Egg pass - Useful if you want to adopt extra eggs in a day, but check if there are other GP items that may be better to save up for first. Incense - Some baby eggs may pop up in the shelter, but a set of one of each incense isn't a bad goal to work toward. Advanced upgrades - These aren't necessarily critical for dexing. Purchase when you feel like it. Ditto - Ok, not really an "upgrade," but we all know that Ditto can breed with any other pokemon (as long as their egg group isn't "undiscovered"). Ditto's kind of hard to get a hold of, but not impossible. You'll get a Ditto Pass when you hit Champion Rank (420 unique eggs dexed, and 900 total dex entries). If you want a Ditto before that, Ditto eggs will *rarely* appear in the Lab. Keep refreshing those Lab eggs, and maybe you'll eventually find one!

You might be tempted to ignore the Wishforge badges, since they take dedicated hatching of the same type to gather the gems for upgrading. Wishforge badges, however, help you hatch eggs and level pokemon a lot faster, and are quite useful to level up! Thankfully, you'll be hatching a lot of pokemon anyway, and you'll probably start accumulating enough gems for the first few levels of Wishforge badges. Don't forget to check the Wishforge, trade in your gems, and upgrade your badges!

Probably your biggest Credit sink at the beginning. You'll want to hold on to Pokemon so you can evolve them, and to hold onto them, you'll need fields. Figure out a sorting scheme you like, and buy fields as you have the money for it. Fields can also be useful for happiness evolutions, as Pokemon will gain happiness from fields they have an affinity with. Some pokemon also have to be in a specific field type in order to evolve.

Seems kind of trivial at first, but making pokeblocks from berries can be a good source of credits, and joining weekly contests is a good GP income. Try to have a crop growing in the background when you can, to work on growing your garden size. Perfect Berries - Some pokemon require Affection (different from Happiness) to evolve. You can either grow them, or buy them from the Market.
