Reconcile and conciliate overlap in restoring agreement between people -- but "reconcile" carries a second, completely unrelated business sense that "conciliate" never does.
"Conciliate" means actively, diplomatically bringing a hostile or resistant party into genuine agreement. "Reconcile" can mean the same thing between people, but it also names a routine financial process: matching two sets of records and explaining any differences. That second sense has nothing to do with people or diplomacy at all.
Conciliate: always interpersonal
Conciliate is never about numbers or records. It's always about a person, group, or dispute being brought to agreement.
"She conciliated the two department heads after months of disagreement over the roadmap."
Reconcile: two senses, one word
Reconcile can describe the same interpersonal work...
"They finally reconciled after a year of tension between the teams."

"Finance reconciled the vendor invoices against the purchase orders and found a $4,000 discrepancy."
That second sentence has nothing to do with hostility, distrust, or agreement between people. It's a matching-and-verifying task.
The test
Ask what's being matched or resolved: is it two sets of records that need to agree on paper (reconcile, financial sense), or a hostile or distrustful party that needs to be brought into genuine agreement (conciliate, or reconcile in its interpersonal sense)? "Conciliate" is never correct for the financial sense -- you cannot "conciliate the accounts."
Wrong: "Finance conciliated the vendor invoices against the purchase orders." Right: "Finance reconciled the vendor invoices against the purchase orders."
The rule
If the sentence is about verifying that records match, only "reconcile" works. If it's about the active, diplomatic effort to bring a resistant party or two opposing parties to agreement, either word can describe it -- "conciliate" is the more precise, skill-crediting choice, while "reconcile" leans slightly more toward the state of being at peace again, without necessarily naming the diplomatic effort behind it.
Practice scenarios
Practice choosing between conciliate and reconcile in situations like:
- describing a finance team matching invoices to purchase orders
- describing a manager bringing two hostile teams to agreement
- correcting a sentence that misuses "conciliate" for an accounting task
- writing a report that needs the right word for each context
Useful practice phrases:
- "Finance reconciled the accounts and flagged a small discrepancy."
- "She conciliated the two teams after a long-running disagreement."
- "They've since reconciled, though it took real effort to get there."
Records get reconciled. People get conciliated -- or reconciled. Only one of those words ever touches a spreadsheet.
