“We implement NetSuite for a living, and we trust Hundred MS with our own accounting. That says enough.”Jon Bourke, CEO of Encompass Digital, a NetSuite solution provider
The people who handed us their books, under their own names.
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.
Tuan PhamCFO, Case-Mate
Accounting · Financial modeling · NetSuiteWhen Hundred came along, our books were a year behind and our NetSuite was improperly implemented. They fixed both. Now we have a monthly close and better ERP operations.
Michael JeromeCEO & Co-Founder, VuPromo
NetSuite implementation · Catch-up close · ReportingHundred MS elevated our month-end close game by implementing AI into all our financial operations, super seamlessly. I was skeptical in the beginning. Now we have a faster close, cleaner books and schedules. Super happy about that.

The questions people ask before they trust anyone with their numbers. If yours is not here, ask me directly.
Yes. The AI works inside your own systems with read-only access. It never sees a password: a person logs in, the AI reads. It cannot move money, post to your ledger or send anything outside. Every sensitive step needs a human.
Sometimes, like any tool. That is why nothing ships on the AI’s word alone. Every number must tie to a source document, every schedule must reconcile to the live ledger, and a senior accountant checks the result. When something slips through, it becomes a written rule so it does not happen twice.
We replace hours, not people. The mechanical work (pulling data, matching, tying out, drafting) goes to the AI. Judgment, policy and accountability stay with people. If you would rather keep everything in-house, we set the same system up inside your team and train them to run it.
A person, always. Every entry is reviewed and posted by a senior accountant, and every report goes out under our name. You know exactly who to call.
Within 10 business days of month-end. We guarantee that from your third month with us; the first two are cleanup and setup. Most clients get there sooner.
Yes. Cleanup and catch-up is where many of our clients start. One came to us a full year behind, with a NetSuite that had been set up wrong, and now closes every month. We rebuild the books period by period, reconcile every balance to a source document, and then move you onto a monthly close by business day 10, guaranteed from your third month.
No. We work in the system you already have: NetSuite, QuickBooks Online, Sage or Xero. If a move to NetSuite would genuinely pay for itself, we will tell you and show the numbers. If it would not, we will tell you that too.
Both. We implement NetSuite, migrate to it from QuickBooks, Sage and other systems, and run the day-to-day accounting inside it. 9 of our people are NetSuite-trained and 2 are NetSuite-certified. We are an independent firm, so we set the system up around how you work, with no over-building and no under-building.
A fraction of what the small team this work normally needs would cost. The exact price depends on your systems and volume. You can work with us on a project, monthly or hourly, and the discovery call ends with a written quote.
Hundred MS LLC is a US company in St. Petersburg, Florida, with a European entity in Frankfurt. Most of our clients are US companies and we work on US hours.
Practical how-tos, checked by the people who do the work. No sign-up, no sales pitch.
