How an Accountant Can Process 3x More Invoices Per Day with Make, Mistral AI and Google Drive
Amina, independent accountant in Paris, now processes 45 invoices/hour instead of 15, saving 3 hours daily. Full guide with Make, Mistral AI and Google Drive.
The Independent Accountant's Paradox
Amina, independent accountant in Paris, spent 3 hours daily on manual data entry -- time stolen from advisory work. McKinsey (2024): accountants spend 42% of their time on entry tasks that could be 80% automated.
With Make.com + Mistral Large 2 + Google Drive, she went from 15 to 45 invoices/hour, reduced error rate by 80%, and recovered 3 hours daily.
The Full Technical Stack
Step 1: Receipt and storage - Make.com monitors Gmail and files attachments in the right Google Drive folder (per client, per month).
Step 2: Data extraction with Mistral Large 2 - Extracts supplier name, SIRET, date, invoice number, HT/TVA/TTC amounts, order reference, IBAN. 94% correct extraction rate on standard invoices.
Step 3: Integration into Google Sheets and Pennylane - Amina only validates lines flagged "uncertain" by Mistral Large 2.
Step 4: Automated weekly report - Every Friday: total invoices per client, collected/deductible VAT, duplicate alerts.
Measured Results
Invoices/hour: 15 to 45. Error rate: 3.2% to 0.6%. Daily entry time: 3h to 0.5h. Weekly advisory hours: 12h to 17h.
Bpifrance (2025): accountants who automated data entry increased revenue by 25% in 6 months.
Gartner (2024): 65% of accounting entry tasks will be automated by 2027.
