If you had ran into me, I might have been able to help
Generally, Merchants tend to pump Str first with Dex and Agi/Vit usually following very close unless you are going for a Pure forger/potter build which I do not recommend for a non-trans job. Str obviously increases your damage while Dex is a major stat once you become either of the second jobs as it is factored-in in forging or brewing as well as slightly increasing your damage and ASPD and decreasing your skill delay. Moderate Agi is good for building up some ASPD and Flee that should allow you to dodge some monsters' attacks while Vit will give you much needed HP, HP regen as well as increase the heal given by potions which, as a Merchant, you will rely heavily upon at later levels. Luk isn't needed as much as the others and can safely be kept at a maximum of 10 without actually affecting you that much (Note though that Luk is also one of the major factors of forging and brewing alongside Dex but due to the latter's better benefits, it is generally chosen over Luk). Lastly, Int isn't really that important as your skills tend to have low SP cost although getting it to a decent level might help you when you start spamming some of your 2nd job skills. Note that additional Int only shines in Forger or Potter builds which I said I don't really recommend for non-trans.
Some important things to remember:
Str is generally more useful at increments of 10, Dex and Vit at increments of 5, Int at increments of 6, and Luk at increments of 5
Example build for an Alche:
STR-85+5
AGI-74+6
VIT-47+3
INT-17+7
DEX-51+9
LUK-2
A build that can battle as well as enjoy decent brewing percentage. Of course it's all just personal preference and is very much open to criticism and change.
It's all up to you whether you want to become an Alch or BSmith, both have their pros and cons. Sorry for the wall of text and for being a little too vague in some parts but I hoped it helped.
