て・ なくてすみませんsorry for…; sorry I didn't…
What you are sorry about goes in the て-form, and すみません comes after it: "sorry I'm late". For something you didn't do, the て-form is なくて: "sorry I didn't call".
didn't
I'm sorry I didn't get in touch yesterday.
Something you did
Verb in the て-form + すみません
遅れる → 遅れてすみません.
Something you didn't do
Verb: ない → なくて + すみません
連絡しない → 連絡しなくてすみません. "Sorry I can't" is 行けなくて, 手伝えなくて.

Not から or ので
What you are sorry about takes the て-form, not から or ので. English "sorry that…" and "sorry because…" make them look right.
Not said: 遅れたから、
(Sorry I'm late.)
遅れてすみません.
すみません or すみませんでした?
As you arrive, or while the trouble is still going on, it is usually すみません.
With an adjective
An adjective goes in front the same way: くて for an い-adjective, で after a な-adjective.
Sorry about my messy handwriting.
I'm sorry my Japanese is so poor.
With friends, and at work
The first half stays as it is. Only the apology changes.
to a customer

Close neighbours
Thanks are built the same way. The favor is the other person's doing, so it needs てくれて.
Thanks for telling me.
The same two forms with other feelings: what made you glad, sad or worried goes in front.
I was lonely because I couldn't see my friend.
ないでN4
A verb's other negative て-form, for "without doing". An apology normally takes なくて.

More detail
Not the "sorry" of sympathy
すみません is for what you did, or someone on your side did. When English says "I'm sorry" about another person's bad news, Japanese says something else, such as 大変でしたね.
I lost my wallet yesterday.
That must have been awful.
