We started Hundred MS to give finance teams crazy good service.

Hundred MS is a team of accountants, NetSuite specialists and fractional CFOs. We started in 2019 and have never had a sales team. Almost every client came because another client told them to call us.

From the ledger up: how an accounting team became a CFO team.

We earned every step by doing the one before it well. That is why our advice comes from inside the numbers, not from above them.

Small steps, big progress. That is how we built Hundred.

We started Hundred in 2019 to give finance teams service so good that they tell their friends. They did. With no sales team, we grew into 17 accountants, NetSuite specialists and CFOs who have served 43 companies. 26 of them are still with us.

I climb mountains, and they teach the same things this work does.

Small steps, big progress.We fix one process at a time. Month after month it adds up.
Patience.We never rush a close or a migration. Done right beats done fast.
Persistence.We stay on a problem until the number ties.

If a number in your business bothers you, bring it to us. We will tell you honestly whether we can help.

How we work: six principles behind our accounting and NetSuite service.

Most consulting firms sell hours. We solve problems.

How we think

We challenge the brief.: What you ask for is not always what you need. We ask why first.
We fix the process, not just the problem.: Every issue is a chance to remove a manual step.

How we treat you

We protect your interests, not ours.: No padded invoices, no over-building, no pointless work.
We become part of your team.: Never outsiders. Your people keep their jobs and get a better process.

What we promise

We never over-promise.: If something cannot be done, we say so early.
Your data stays yours.: The AI gets read-only access and never a password. People make every change.

“Hundred is like family to us. The relationship we built together doesn’t even feel like we are two separate companies, and that is because they are trustworthy.”

A team that hikes together keeps your books together.

We hike, we travel, and we have dinner together more often than most families.

It matters to you for one reason: people who like working together stay. When your accountant does not change every year, nobody has to relearn your business.
