How a tech entrepreneur turned an AI coworker into a full operating system for work and life. Then her firm did the same.

“I don't have to select the connectors and can have the AI within Slack without needing another app. The team can use it with ease in the same place together.”

Two Sides Accounting is a boutique, fully remote accounting firm based in Sydney's south. Natalie Lennon runs it with a team of four: a practice manager and three accountants. They manage a hundred and thirty-one client files on Xero, handle everything from weekly bookkeeping and BAS lodgements to tax planning and payroll, and Natalie co-hosts the Accountants After Hours podcast with six external collaborators.
Every morning started the same way. Open Outlook. Scan the inbox. Open the calendar. Manually categorise events. Open Karbon to check team work status. Open the podcast spreadsheet to see if deadlines were being hit. By 8am she'd burned an hour on pure triage before touching a single piece of client work.
Timesheets were the worst, not because they were hard, but because they didn't happen. "I didn't do it before as I kept forgetting," Lennon says. No visibility into chargeable ratios. No early warning when someone was spending five hours on a client that should take two. The podcast was its own universe: six collaborators, their own deadlines, their own spreadsheet tabs. And new client leads were being captured in Typeform at $56 USD per month, piped through Zapier, and still requiring manual data entry into two separate Google Sheets.
Viktor was installed on 20 May 2026. Natalie skipped the onboarding flow. Viktor introduced itself, read the workspace history, and proposed three workflow ideas within the hour. Seventeen minutes later, Natalie's first real task arrived: design a social media post about the Federal Budget. Not a test, a real task, for a real client audience, during one of the busiest policy weeks of the year.
Within week one, three integrations were live (Canva, Google Drive, YouTube) and the first scheduled task was running. By the end of week two, Outlook, Karbon, Xero, HubSpot, Buffer, and Mailchimp were all connected.
Lennon had been using ChatGPT and Claude before Viktor. She barely opens Claude now. The difference wasn't capability, it was where the work happened. Viktor lives inside Slack, pulls context from connected tools automatically, and runs recurring work without being asked. No separate app. No pasting data into a chat window every session.
Lennon arrived with a wish list. Most of the fifteen workflows were things she already knew the firm needed; Viktor suggested one or two on its own. She described what she wanted in Slack, in plain English, and Viktor built, tested, and scheduled each one. No configuration screens. No flowchart builders. No code.

Five more are paused, including Megan's daily brief, email draft replies, and monthly marketing dashboards, either superseded by better versions or waiting on integration improvements.
Beyond the scheduled tasks, Viktor handles ad-hoc work on demand: corporate structure diagrams, Xero health checks, TPAR preparation, end-of-year workpapers, LinkedIn posts via Buffer, email drafting in Outlook, website traffic analysis, and batch work item creation in Karbon.
“Being able to do bulk tasks in Karbon is an absolute game changer. Already saving quite a lot of time, but my practice manager estimates it will save hours and hours once our tax season kicks off.”

The firm manages a hundred and thirty-one client files on Xero, twenty-five already connected to Viktor, with the rest being rolled out. Viktor can pull trial balances, run health checks, or generate workpapers for any connected client directly, without Natalie logging into Xero. On top of the Xero connections: Karbon, two Outlook accounts, two Outlook calendars, Buffer, Canva, Google Drive, Gmail, Google Analytics, Google Docs, Granola, HubSpot, Instagram, LinkedIn, Mailchimp, Spotify, Wix, and YouTube.

For an accountant handing an AI employee the keys to 131 client files, the trust question comes first. Lennon checked Viktor's security credentials, then applied a practical test: if Xero and Microsoft were comfortable granting API access, she was too. Viktor has no access to Xero Payroll: tax file numbers, dates of birth, and other confidential employee data never leave Xero.
“I checked the security level, but I felt that if Xero and Microsoft were comfortable connecting, then I was also.”
- Natalie Lennon
Viktor started as Natalie's. Within the first week, it became the team's. Megan, the practice manager, got her own Outlook connection, calendar integration, and morning brief. The three accountants don't interact with Viktor directly yet, but their timesheets are reviewed weekly, their work appears in the Karbon brief, and they joined #workflow in June to see Monday overviews alongside the rest of the team.
“Megan is one of our older team members that has been a little sceptical of AI tools until now. This is the first AI tool she has been excited about.”
- Natalie Lennon
Natalie also set up dedicated Slack channels for key clients with uploaded meeting transcripts for context, plus private channels for her TS Academy mentoring clients.
At the bottom of the firm's rate card, eight hours of recovered time is worth $1,600 per week, roughly $6,900 per month in billable capacity. Viktor costs $200 per month. Even at the most conservative estimate, the return is more than thirty times the cost.
Typeform has been cancelled ($56 USD/month). Zapier is next, pending a Kajabi integration. Tax season hasn't started yet. The bulk Karbon workflows haven't hit peak volume. The real math comes in August.
Social media is the biggest gap. Viktor can draft posts and schedule them through Buffer, but the Buffer API won't accept video uploads from a link. For a firm that creates regular video content, that means social media scheduling still isn't fully automated.
Five scheduled tasks are paused, some superseded, some needing iteration. The lead form had a rough patch: after Viktor replaced Typeform, junk submissions increased. Filtering rules are still being tuned. Kajabi remains unconnected, keeping Zapier in the stack.
Twenty-eight days in. Fifteen workflows built, ten running. A hundred and thirty-one client files. An hour back every morning. More than $6,900 per month in recovered capacity for a $200 plan. Typeform cancelled. Timesheets reviewed for the first time.
It's not done. Tax season will be the real test. But the founder of a five-person accounting firm now starts her day reading a brief instead of building one.
