Bank to bank is best. Let your BDO bank know ahead of time, with supporting documents, that you'll be receiving a remittance of that amount. Ask your German bank to do a SWIFT transfer, and remember to type the receiving account holder's name exactly as it appears on the account to avoid delays. If all goes well it takes 2-3 days.

I've used Wise for a long time with no issues. I've sent up to ₱1 million to BDO accounts. In my experience the problem isn't Wise, it's the receiving bank - BDO sometimes rejects it. For big amounts, it's worth having the recipient see their BDO account manager and let them know a large sum is coming. I believe they do anti-money-laundering checks and ask for proof of the source of funds, passport copies and so on.

Don't post here how much you're sending

Please make sure the recipient's bank can receive this amount, because some banks in the Philippines won't accept large transfers directly. That happened with my sister's bank, they only take money through remittance services. It's best to notify both banks in advance and confirm the transfer can be received. That way you avoid delays, holds or other problems.

For our house build, I moved the big sum into a Wise PHP account and then moved smaller amounts into BDO each week to withdraw for wages or transfer to suppliers. If you need the money for a single purchase, like a car, I did a bank-to-bank transfer, which takes time and can get blocked at random. The real issue, though, is getting it out of the PH bank account - when I bought my car they wanted to see the bill of sale and registration before letting me have my own money - and then it still needed extra approval from head office because it was over 500k in one day - took about 4 hours in the bank even though I was just transferring bank to bank to the seller, not cash…. PH bank tellers don't seem to have the authority to even blow their own noses, so be ready for delays and hoops to jump through.
