The Strategy
Alexandre Contador advises early-stage SaaS founders on go-to-market and runs the whole thing solo, which means the billable work competes directly with the admin. Their answer was not one big assistant but eleven small, specific Claude workflows, each aimed at a task that used to cost an evening. The set covers the entire operating rhythm of a one-person consultancy: a morning priorities brief, proposal generation, invoice and payment follow-up, content drafting and scheduling, lead qualification with auto-reply, meeting notes into CRM, a weekly revenue and pipeline report, client onboarding, tax and expense tracking, and an end-of-day shutdown routine. Nothing here needs custom infrastructure. The workflows reach into Gmail, Google Calendar, Notion, Slack, Canva, Supabase, web search and Figma — the tools they were already paying for — and the total monthly cost lands between €18 and €38 depending on what you already run. The economics are the sort a freelancer can check against their own week. Proposals dropped from two to three hours down to about five minutes of review, which they estimate at eight to ten hours recovered weekly on proposals alone. The expense-tracking workflow found €280 a month in forgotten subscriptions in its first week, and the payment follow-up recovered an overdue invoice that covered a year of the tooling.
How It Works
Inventory the recurring non-billable tasks that actually eat the week: proposals, invoicing, follow-ups, notes, onboarding, reporting.
Build one narrow workflow per task rather than a single general assistant, so each one can be tested and trusted on its own.
Connect the workflows to the tools already in use — Gmail, Google Calendar, Notion, Slack — instead of moving work into a new system.
Start the day with a priorities brief that assembles calendar, inbox and pipeline into one short read.
Turn call notes and job posts into proposals automatically, keeping the human step as review rather than authorship.
Automate invoice and payment follow-up on a schedule, since chasing money is the task most freelancers postpone.
Qualify inbound leads and send a first reply automatically so response time stops depending on whether you are at your desk.
Run an end-of-day routine that closes the loop: notes into CRM, tomorrow's priorities, nothing left in your head overnight.
Results
Alexandre Contador reports three to four hours a day previously spent on non-billable work, proposals reduced from two or three hours to about five minutes of review, roughly eight to ten hours recovered weekly on proposals alone, €280 a month in forgotten subscriptions found in the first week of expense tracking, and one recovered overdue invoice covering a year of tooling cost. Total running cost is put at €18 to €38 a month. All figures are self-reported and have not been independently verified.
Our Take
This is the least exotic entry in this batch and probably the most immediately useful one for a freelancer. There is no fleet, no orchestration layer, and no infrastructure to maintain — just eleven bounded workflows sitting on tools you already pay for. The strongest single idea is automating invoice and payment follow-up, because it is the task solo operators most reliably avoid and the only one on the list that directly returns cash. We would treat the proposal time savings as the honest headline and the revenue framing more carefully, since faster proposals only matter if the pipeline exists to send them to. Best suited to consultants, freelancers and one-person agencies who want the admin half of the job to stop expanding.
